Bugger - that was a breakdown in my packaging process :(
pywin32.version.txt still has 210.9 in it, but you certainly have build 211
there.  My apologies - you can edit this .txt file if it worries you.

I was able to resolve this. The file application was interacting with resided
on a network share. Once I copied it to a local volume I was able to
manipulate the string without a problem.

Hi Mark

You are of course correct, I should have said I am developing on a 64 bit
machine.

Spotted that and thanks for the setup  tip, I also spotted there is a 2.6 64
bit build this seemed to install ok with python 2.6 ok, so I will probably
just use that. What compiler was used for this package?

Point duly noted, I will examine 2.6 instead then and see how it goes. SO
long as I can get all the tests running without any problems then I will be
happy, and by the time we deploy it looks like 2.6 should be pretty much
ready.

Thanks again,

Hi!

Since release 211, I have dozens & dozens messages, like this:

pythoncom warning: PyVARDESC ctor has unknown varkind (3) - returning None

Hello,
I've passed some time reading the MS coding guide for Vista 
http://msdn.microsoft.com/en-us/library/bb756973.aspx

It explains that an app requiring administrator rights (modify HKLM, 
write in C:\Windows\, etc.) will always return "Access denied" or ask 
the user for UAC if it's launched with the appropriate manifest or with 
"runas".
You can personalize the UAC prompt by a short description of your 
program and an icon.

In short, if your user app does something like that, rewrite it using a 
service.

Subject: [python-win32] adodbapi SQL access micro how-to (pywin32 build 211)
Message-ID: <b7eb4a700806021504p593e13f3y976c3efc24e51a1@mail.gmail.com>

I've just had a success story with the adodbapi now included in build 211,
and thought it would be a good idea to let everyone know how to do it.

My application ran a very gnarly SQL script against master..sysprocesses to
identify blocked SQL requests. It tended to crash python when the MSSQL
server was running badly, which was, of course, when I needed it most.  It
happened again today.

I replaced:
import dbi, odbc
conn = odbc.odbc("Oasis Data/oareport/xxxxx")

with:
import adodbapi
conn = adodbapi.connect("DSN=Oasis Data; Uid=oareport; Pwd=xxxxx")

and presto! the script runs with no errors and no other changes.
<http://www.connectionstrings.com>
A working example of creating and connecting to a Microsoft Access type
(a.k.a. "jet") database can be found in
Lib/site-packages/adodbapi/tests/adodbapitestconfig.py. There are also
MSSQL, mysql, and AS400 examples in that file.

Connection string examples for many other situations can be found at

Hello Tim,

Thank you for your reply. I tried to use the setPath method and no luck:

In [26]: item.setPath('')
---------------------------------------------------------------------------
exceptions.AttributeError                            Traceback (most recent call last)

    453                 if args is None:
--> 454                         raise AttributeError, "'%s' object has no attribute '%s'" % (repr(self), attr)
    455                 return self._ApplyTypes_(*args)
    456

AttributeError: '<win32com.gen_py.Expression Media 1.0 Type Library.IMediaItem instance at 0x20535736>' object has no attribute 'setPath'

I did dir(item) and there were no set/get methods, just the ones provided by the application's COM. The item.Path attribute appears to just be a unicode string.

-2147467259 is 80004005, which is the rather unhelpful E_FAIL.

Sometimes, when it is mapping a settable/gettable property, the Python COM mapper creates a separate method for setting.  You might try:
    item.setPath( "" )

Subject: [python-win32] USB CDC-class support with win32file,
	exception processing issues
Message-ID: <ed16a6df0806021530p46d7ae2cs15c074ffd0e69ada@mail.gmail.com>

When USB communication device class devices are installed in Windows
they appear as COMxxx ports, just like legacy serial ports. They are
different in that many RS-232 device parameters don't apply (such as
baud rate, handshaking, etc). Also, since they are USB devices they
may be suspended while remaining connected (as when the computer goes
into sleep mode), or may be unplugged at any time.

I am creating a simple Python communications library to support
USB-CDC devices, ignoring the unused legacy features but adding
suspend and disconnect support. I have found some problems with
exception processing that is making this problematic.

win32file.WriteFile works well. If the device is suspended I get
pywintypes.error (31, 'WriteFile', 'A device attached to the system is
not functioning.'). If the device is unplugged I get pywintypes.error
(1167, 'WriteFile', 'The device is not connected.').

I can find out if there are any characters in the input buffer using
win32file.ClearCommError. Its exception reporting half-way works. If
the device is suspended I get pywintypes.error (31, 'ClearCommError',
'A device attached to the system is not functioning.'). But if the
device is unplugged I get no error reported at all.

win32file.ReadFile provides neither of these errors. Either suspended
or unplugged just causes ReadFile to hang. I can get ReadFile to
return if I set a timeout, but no error is reported so I don't know if
it returned because the device hasn't sent the data yet, or because
the device is suspended or disconnected.

Is there some way to get ReadFile to report errors 31 and 1167 like
WriteFile does? Or is there some other way to determine port status as
"attached but not functioning" or "not connected"?

Thanks for the help!

Seeing as nothing has caught fire in the few days since I made the release,
I updated the SF page to point at build 211 - it does still have a note that
b210 is the "most recent stable version", so I think it's a good compromise
:)

 

Cheers,

Given there have been a large number of changes since the last release, I

this release has been extensively tested recently, so I don't anticipate any

Now that you mention it, my power supply flamed out.
If I determine it was due to build 211, I'll file a bug report. ;)

It happens as part of the makepy generation process, apparently when
processing the "default" value for params.  In b210 and earlier, when
pythoncom saw a VARDESC it didn't understand, it silently returned None, but
in b211, as you see, it generates a warning as it implies there is something
pywin32 needs to fix (the *bad* think about such warnings is that there is
nothing the person seeing the warning can do to resolve it other than ask
about it, as you have done)
 
It appears we are hitting a VARKIND of VAR_DISPATCH.  Does it happen for you
on any typelibs I'm likely to have installed?  Any idea what in your
typelibs could cause this, so I can repro it in the test suite?

Cheers,

Mark.

I'm afraid I don't have many insights.  Using overlapped IO may solve your
problem of not knowing if an error occurred or not, but I don't think it
will solve your general problem.  One thing that might be worth looking at
are "device notifications", which may be able to inform you of the removal -
see win32\Demos\win32gui_devicenotify.py in build 211 for an example (I
think that only will see mass-storage devices, but if you dig around MSDN
you may have luck)

Cheers,

Subject: [python-win32] Service does not start at windows boot but at user's
	login
Message-ID: <48468A9B.8010401@linbox.com>

Good morning,

I'm currently building an application which involves two different 
processes : one is a service and the other one is a simple client.
My client starts at user's login and the service should start at windows 
boot. I say 'should' because it seems that the service
actually starts at user's login too : I put logs in the event log and I 
noticed that the service starts almost 7 to 10 seconds after
the client, which is not what is expected. Service's properties are : 
run automatically on System account, no dependencies.
The code of my service is based on the one found in the book : Oreilly, 
Python Programming on Win32, at chapter 18.6 :
Sample Service Written in Python.


Furthermore, my two processes communicate through a named pipe, and the 
problem aforementioned involves that the communication
is not possible : indeed, the service, who should start before the 
client, creates the pipe and waits for a client connection. Client has just
to open  the pipe to connect. But obviously if the client starts before 
the service, an error occurs because no pipe is created so far.

I did a lot of searches to solve this problem, but haven't found any 
issue yet.
I first thought that  the problem came from pythonservice.exe, which 
hosts my service : it may take longer time
to load than common other windows services. That's why I converted my 
service into a .exe thanks to py2exe. Then the path in service's
properties has changed to this executable. But the problem remains : 
service still starts after client.
However, the problem only occurs at first user's login after machine's 
boot : if he disconnects and somebody connects after, without reboot, 
the service is
still running, which is normal.

That's why I would ask if anyone  has an idea for solving this problem.
Thank you in advance for your answers.

XP and Vista both pull a few tricks to get you logged on before all services
have started - there are no guarantees that all services will be started
before any user programs.  It's probably best to just have your client deal
with the situation (either by blindly, but smartly, retrying, or by querying
the service status and waiting until it is reporting it is started.)

Sadly I don't have that installed :(  I think I forgot to select that option
when installing Outlook 2007.  EnsureDispatch("Outlook.Application") doesn't
show the problem for me either - so I guess I'll see about installing MAPI
support tomorrow.

In the meantime, any other takers? :)

I run Windows 2003 Server with automatic logon. It seems to me that some 
services are started after the logon. I base this on noting that I get 
the Some Services Did Not Start alert many seconds after my desktop has 
appeared.

Could the client repeatedly try connecting with some reasonable delay 
between connection attempts?

Thank you for feedback.

I have already solved the problem of the connection of the client after 
the service : the client waits until the server has started.
It works by putting a delay between each connection attempt, but I 
prefered play with exception returned when the pipe isn't
opened yet : I wait until this exception occur : when the pipe has just 
opened, my client works. If I put a delay,
I have chances not to see the opening of the pipe when it just occurs.

But the big problem is that my service has to alter some registry keys 
in HKLM hive, and these changes have to be done after any user login : 
indeed,
 I would like to set these keys at windows boot in order that when 
anyone logs in, the changes take effect. If the changes are done at 
user's login,
(which is the case because the service starts after the client) then 
they will only be effective when the user reboots, so the user has to 
reboot and
it's not what I want : I want to put changes at windows boot so that 
when a user logs in, changes are validated and he doesn't have to reboot.

I use a Vmware Server Console with Windows XP Service pack 2 on it. I 
noticed some time synchronization problems as my clock was very quick :
one minute in the reality almost equals to 3 on the machine. It could 
have an influence on the boot of my programs. I solved this problem with 
Vmware tools,
so I could synchronize clock with my host operating system, but it 
changes nothing to the main problem...

You need the SetSystemPowerState [1] function from kernel32. 
(And your process will need to enable SeShutdown as well).

<code>
import ctypes
import win32api
import win32security

#
# Enable the SeShutdown privilege (which must be present in your
# token in the first place)
#
priv_flags = win32security.TOKEN_ADJUST_PRIVILEGES | win32security.TOKEN_QUERY
hToken = win32security.OpenProcessToken (
 win32api.GetCurrentProcess (),
 priv_flags
)
priv_id = win32security.LookupPrivilegeValue (
   None, 
   win32security.SE_SHUTDOWN_NAME
)
old_privs = win32security.AdjustTokenPrivileges (
 hToken,
 0,
 [(privilege_id, win32security.SE_PRIVILEGE_ENABLED)]
)

#

Not really my area of expertise, but might it be possible to use
one of the RunOnce keys in your circumstances?

Subject: [python-win32] Autocad automation via COM
Message-ID: <3d26fb440806050344w3dbb9791r1c185c0f684dbdbc@mail.gmail.com>

Hello,
I'm new in this mailing list.
I'd like to discuss this problem with pywin32 and autocad:
autocad awaiting parameters to functions as variants, but in fact, it
must be for example array of doubles x,y,z.
The problem and some fix by patching build.py script is described
here: http://www.mail-archive.com/python-win32 at python.org/msg01445.html

Descibed fix (by AutocadTranslateMap) works fine, except in one (or
two) situations:
Autocad ActiveViewport.SnapBasePoint property awaiting 2-element array
of doubles x,y (unlike many other functions awaiting 3-element array
of doubles x,y,z).
In this situation it fails and autocad raises error about wrong
parameter. If you print ActiveViewport.SnapBasePoint you will get
(0.0,0.0).

In Dan Glassman's fix
(http://www.mail-archive.com/python-win32 at python.org/msg01445.html) in
AutocadTranslateMap you can see snapbasepoint parameter here with 8197
type, which I think is array of doubles.

I don't understand COM, I'm not programmer, I'm only user, so please,
can somebody help me with this problem? I can send patched build.py
(patched as described in
http://www.mail-archive.com/python-win32 at python.org/msg01445.html) and
I can send gencache file
gen_py/EE2303F2-4EF6-42F6-92AB-4241221FF278x0x2x5.py where you can see
defined "SnapBasePoint": ((13, LCID, 4, 0),()),... and in other places
(I don't fully understand what it means).

Thank you very much for any information / help.

My client starts at user's login. This is made by putting a value in the 
Run key of HKLM hive. My Service is configured to start
automatically at windows boot. For a program whose path is set in a 
RunOnce key, it obviously only starts once, but it's still at user's 
login and not
at windows boot.
I am still working on that problem, I'll post as soon as I get news.

Thanks,

Subject: [python-win32] event Makepy question
Message-ID: <004b01c8c729$bfc73830$0a01a8c0@bureauserge>

Hi, 

 To develop a interface to a COM library under Boa Constructor and WxPython, Python 2.5, I had to use the makepy utility to generate the classes file.

 I show you a part of this file:

 from win32com.client import CoClassBaseClass
# This CoClass is known by the name 'PcommServer.PmacDevice.1'
class PmacDevice(CoClassBaseClass): # A CoClass
 # PmacDevice Class
 CLSID = IID('{B544D2BD-354C-456E-9E88-20F71625E7DF}')
 coclass_sources = [
  _IPmacDeviceEvents,
 ]
 default_source = _IPmacDeviceEvents
 coclass_interfaces = [
  IPmacDevice,
 ]
 default_interface = IPmacDevice

I can call PmacDevice() class and everything works well to communicate with the card. There is events managed in the library and I don't know how to use them? There is nothing in the file concerning this class.

 Do you have a example or tutorial ?

 Thanks a lot.

 Serge Gauthier

You need the SetSystemPowerState [1] function from kernel32. 
(And your process will need to enable SeShutdown as well).

<code>
import ctypes
import win32api
import win32security

#
# Enable the SeShutdown privilege (which must be present in your

#
priv_flags = win32security.TOKEN_ADJUST_PRIVILEGES |

 win32api.GetCurrentProcess (),
 priv_flags
)
priv_id = win32security.LookupPrivilegeValue (
   None, 
   win32security.SE_SHUTDOWN_NAME
)
old_privs = win32security.AdjustTokenPrivileges (
 hToken,
 0,
 [(privilege_id, win32security.SE_PRIVILEGE_ENABLED)]
)

#

To complete this, the application is launched at logon (via Userinit 
registry key). It rewrites paths to StartMenu and Desktop according to 
the type of logon (Domain or Local).
Actually it only rewrites when it is a local session and user IsAnAdmin. 
The application as to re-run itself using ShellExecute so it has to know 
if it already runs elevated or not.

To do this I must use :
GetTokenInformation(
                     hToken,
                     TokenElevationType
		    )

Unfortunately win32security.TokenElevationType (18) is not available. 
And GetTokenInformation(hToken, 18) returns
 >>> win32security.GetTokenInformation(hToken, 18)
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
pywintypes.error: (87, 'GetTokenInformation - size call', 'The parameter 
is incorrect')


Is it possible to do this using ctypes ? How ?

I'm not running Vista, so I can only go so far with this, but
with the latest pywin32 v211, this works:

<code>
import win32api
import win32security

hToken = win32security.OpenProcessToken (
   win32api.GetCurrentProcess (),
   win32security.TOKEN_QUERY
)
print win32security.GetTokenInformation (
   hToken,
   win32security.TokenType
)

print win32security.TokenElevationType

</code>

That last bit is in there just to show that the
constant is available, even if my XP box can't
make use of it. Assuming that there may be some
kind of bug in the pywin32 code, that last call
could be done in ctypes like this:

<code>
import ctypes
from ctypes.wintypes import HANDLE
import win32api
import win32security

hToken = win32security.OpenProcessToken (
   win32api.GetCurrentProcess (),
   win32security.TOKEN_QUERY
)

token_information = ctypes.c_uint (0)
return_length = ctypes.c_uint (0)

GetTokenInformation = ctypes.windll.advapi32.GetTokenInformation
GetTokenInformation (
   HANDLE (int (hToken)),
   win32security.TokenType,
   ctypes.byref (token_information),
   ctypes.sizeof (token_information),
   ctypes.byref (return_length)
)

print token_information
#
# Should print 1, representing primary token
#
</code>

[
BTW I consider it a testimony to the developers and
maintainers of the pywin32 and ctypes extensions that:
(a) this code works at all
(b) it worked first time even though I'd typed it
up directly in an email
(c) it remains remarkably readable, in spite of calling
the Windows API directly.

What about:

>>> from win32com.shell import shell
>>> shell.IsUserAnAdmin()
True

?  See the docs though, to ensure you correctly handle the win2k etc cases
(and it requires build 211)

Alterntively, it seems to me that you can maybe *assume* you are not
elevated first time you are run, and always attempt to re-execute yourself.
For example:

%python -c "import win32api;win32api.ShellExecute(0, 'runas', 'notepad.exe',
None, '', 1)"

If run from a normal command prompt, it will prompt for elevation - but if
the command prompt is already elevated, it silently opens notepad.  So, you
could try something like:

* Arrange for 'myprogram.exe' to be started.
* myprogram.exe checks for a '-no-elevate' command line - if not there, it
just re-executes itself, but *with* the '-no-elevate' param. 

Although this will always execute your program twice, it will only prompt
for elevation when necessary.  As you imply that the most common case is
likely to *not* be elevated in the first instance, the net result is the
same.

Cheers,

Mark

Message-ID: <484BC6C2.5010405@eccam.com>

Hello all,
I'm trying to embed IE to a GTK app and control IE behavior via the  
DWebBrowserEvents2 interface.
Embedding works, events  like OnBeforeNavigate2 or OnNewWindow2 are 
comming  fine but when I try to return (from the callback) a Cancel 
value which suppose stop IE from next page loading or new explorer 
window creation, the program either crashes or doesn't prevent IE from  
moving to next page or opening a new window.

Any idea how I could approach this problem?

Bellow are details and code snippets.

Thanks a lot,

If this is being used in a control, you probably need one extra "out" param
used by the control window framework in pythonwin.  In my code, I've been
unable to effectively cancel the OnBeforeNavigate2 event though, but I don't
think its related to pywin32.  I could get the OnNewWindow3 event to cancel
though, with code like:

    def OnNewWindow3(self, ppDisp, Cancel, dwFlags, bstrUrlContext,
bstrUrl):
        #print "NewWindow", `bstrUrlContext`, `bstrUrl`
        if i_want_to_cancel_it:
            # cancel the event
            return 0, None, True

That first out param is the extra one I referred to above, and I can't
recall what the 2nd out param is but the 3rd is 'Cancel'

Hope this helps,

Mark

I encounter a problem when trying to install it. I get prompted by a 
secure window (a window with some keys icons) asking me if I want to run 
it with my account with(out) security against virus or with another account.
None of the 3 possibilities works for me. Any idea ?

Actually it works with XP SP2 but not with XP without SP.

Message-ID: <99a8d4630806090302t33a8a369sb7a69ef94b4af4e3@mail.gmail.com>

Hi all,

I am using the webbrowser control (internet explorer) as display
component in a project. Unfortunately the Tab and Enter keys do not
work, i.e. it is impossible to switch between input fields of the
displayed html-page and it is impossible to enter a newline in an
input field.

Can anyone help?

Message-ID: <00bb01c8ca2c$cc835530$0a01a8c0@bureauserge>

Hi, 

 To develop a interface to a COM library under Boa Constructor and WxPython, Python 2.5, I had to use the makepy utility to generate the classes file.

 I show you a part of this file:

class _IPmacDeviceEvents:
 """_IPmacDeviceEvents Interface"""
 CLSID = CLSID_Sink = IID('{D1C5C7C8-5E0C-495E-9AAF-85B146DA5F13}')
 coclass_clsid = IID('{B544D2BD-354C-456E-9E88-20F71625E7DF}')
 _public_methods_ = [] # For COM Server support
 _dispid_to_func_ = {
          5 : "OnUnsolicited",
          3 : "OnError",
          4 : "OnInterrupt",
          2 : "OnProgress",
          1 : "OnMessage",
          6 : "OnDataReady",
  }

 def __init__(self, oobj = None):
  if oobj is None:
   self._olecp = None
  else:
   import win32com.server.util
   from win32com.server.policy import EventHandlerPolicy
   cpc=oobj._oleobj_.QueryInterface(pythoncom.IID_IConnectionPointContainer)
   cp=cpc.FindConnectionPoint(self.CLSID_Sink)
   cookie=cp.Advise(win32com.server.util.wrap(self, usePolicy=EventHandlerPolicy))
   self._olecp,self._olecp_cookie = cp,cookie
 def __del__(self):
  try:
   self.close()
  except pythoncom.com_error:
   pass
 def close(self):
  if self._olecp is not None:
   cp,cookie,self._olecp,self._olecp_cookie = self._olecp,self._olecp_cookie,None,None
   cp.Unadvise(cookie)
 def _query_interface_(self, iid):
  import win32com.server.util
  if iid==self.CLSID_Sink: return win32com.server.util.wrap(self)

 # Event Handlers
 # If you create handlers, they should have the following prototypes:
# def OnUnsolicited(self, Device=defaultNamedNotOptArg, Msg=defaultNamedNotOptArg):
#  """method Unsolicited"""
# def OnError(self, Device=defaultNamedNotOptArg, FileName=defaultNamedNotOptArg, ErrorID=defaultNamedNotOptArg, LineNum=defaultNamedNotOptArg
#   , Line=defaultNamedNotOptArg):
#  """method Error"""
# def OnInterrupt(self, Device=defaultNamedNotOptArg, lLevel=defaultNamedNotOptArg):
#  """method Interrupt"""
# def OnProgress(self, Device=defaultNamedNotOptArg, dwPercent=defaultNamedNotOptArg):
#  """method Progress"""
# def OnMessage(self, Device=defaultNamedNotOptArg, Msg=defaultNamedNotOptArg, bNewLine=defaultNamedNotOptArg):
#  """method Message"""
# def OnDataReady(self, Device=defaultNamedNotOptArg):
#  """method DataReady"""
;
;
;
from win32com.client import CoClassBaseClass
# This CoClass is known by the name 'PcommServer.PmacDevice.1'
class PmacDevice(CoClassBaseClass): # A CoClass
 # PmacDevice Class
 CLSID = IID('{B544D2BD-354C-456E-9E88-20F71625E7DF}')
 coclass_sources = [
  _IPmacDeviceEvents,
 ]
 default_source = _IPmacDeviceEvents
 coclass_interfaces = [
  IPmacDevice,
 ]
 default_interface = IPmacDevice

I can call PmacDevice() class without problem and everything works well to communicate with the card. 
How to use the events managed in the library ?

 Do you have a example or tutorial ?

 Thanks a lot.

There's also at least one non-pywin32 solution that I keep hearing about 
called the PAMIE project. You might find it helpful:

http://pamie.sourceforge.net/

If nothing else, the source from the project might give you some ideas 
on how to approach the problem.

Message-ID: <484D33C2.7080909@linbox.com>

Good morning everyone,

I may have found an issue for my problem : I've made the service RpcSs 
(Remote Procedure Call SubSystem)
dependent from my own service. Thus, RpcSs will only start when my own 
service has started.
It seems to work. A drawback is that if I want to stop my service before 
shutdown , all dependant services
will stop also, and some of them do not stop properly. Indeed, RpcSs has 
a lot of services depending of it.
But it's already a solution.

I hope this could help other people.

I suppose that the user's program throws an exception if the service 
isn't started yet.

I propose this :

while True:
  try:
	do_what_fails_if_service_isn_t_started
	break
  except:
	time.sleep(0.5)

I've this problem when using wipfw and twisted's reactor.

When you say none of the possibilities work, how exactly do they fail?

I'm sure I could extend the OS check to only attempt elevation on XP with
SP1, but it would be nice to have a better understanding of the failure
before doing that (eg, while testing this, I found Win2k also seems to
support the 'runas' ShellExecute API - but it behaves slightly differently,
and IsUserAnAdmin() isn't available.  So if it (basically) works on Win2k,
I'd be surprised it fails worse on XP without SP1.

Cheers,

Mark

Another drawback is that if your service fails for any reason, a fairly
important part of Windows will also fail to work.  The RPCSS service isn't
*really* dependent on your service; abusing service dependencies for this
reason is (IMO) courting much bigger problems.

Cheers,

Mark

You might want to re-post this to the wxPython user's group just in case 
you're missing a wx method. I use wxPython extensively, but I'm not 
familiar with that particular widget. The link to the mail list is below:

http://wxpython.org/maillist.php

Also, there's the PAMIE project which you may or may not find useful: 
http://pamie.sourceforge.net/

I personally have used the SendKeys module to automate IE, however it's 
rather like black magic and kind of sucks:

Then you use win32com.client.DispatchWithEvents to create

This turned out to be a wxpython specific problem and not a IE problem
as I thought. The solution is to use the IE widget of wx
(wx.lib.iewin.IEHtmlWindow).
Thanks for the help,

PAMIE is quite impressive, I should have known it before.

I totally agree with you. I have found another dependency to use : 
Themes, which is less heavy than RPCSS.
This works, but it does not make exactly what I want. Indeed, I would 
like to set some values in a HKLM subkey
at windows boot, in order that changes are effective as soon as a user 
logs in after boot sequence. In my case,
registry values are well written, but changes aren't effective yet... So 
user needs to reboot.
I tried to use the FlushKey() method from _winreg module in order to 
immediately write changes to registry.
Changes are written, but not effective. I thought that user's login 
refreshed the registry, and then changes could
have taken effect, but it seems not to be really the case.
Is there any other Python _winreg method that could force registry 
changes to become effective as soon as
changes are written into the registry ?

SP

This is not a PyWin32 question.  You need to find a Maya mailing list.  
There appear to be a lot of good resources on Google.

A few minutes with Google seems to show that the "pySource" command in 
MEL executes a Python file, or you can execute short snippet     by saying:
    py "print 'Hello!' "

Plus, it is simply not an acceptable practice for you to change some 
other service's dependencies.

Why?  What are you really trying to do here?  What you're describing 
sounds like a perfect vector for malware and trojan horses.

You can certainly have a domain login script that gets executed very 
early in the login sequence.  That's how most corporate environments 
enforce their IT policies.

Which registry entries are you changing?  Perhaps there is another way.

This is just not the right question.  Any changes take effect 
immediately, but if some other process has already read the value, 
there's nothing you can do, unless there's a way to notify the other 
process to re-read its settings.

Howdy,

Mark, I vaguely recall a brief chat we had at PyCon where you said you'd hooked NTLM into, um, some sort of web-enabled Python environment ;-)  I can't remember the details (hope you can!), but I'm interested in whatever you came up with.  Currently, if I want to 'seamlessly' get a user's Windows domain login credentials, I set up httpd with mod_auth_sspi then redirect/proxy to a Python web-aware program (i.e. something on Twisted).

Would be nice to hook the NTLM stuff directly into the Python request/response http level, if possible.

Check out win32\demos\security\sspi - there you should find enough info to
get you started, including a *client* that uses NTLM to authenticate with a
server (which means in practice, you probably need to configure IIS for NTLM
auth to test this)

The issue with integrating it into httplib or similar is that the
authentication process is quite different than http basic auth.  In summary,
NTLM is a multi-step challenge/response system - ie, you end up taking a
number of requests, often 3, to get a "secure" channel.  Further, it is the
channel itself which is secured - eg, the socket.  Once the socket is
closed, you must re-authenticate from scratch again - the info you
negotiated in your first connection is no longer any use.

The only way I could find to integrate this with a httplib style class was
to implement an "onrequest callback" - a hook that the connection class
would call with the raw headers etc, and a way for that callback to modifiy
the request headers and tell the class to retry the operation with the new
headers.  At some stage, the callback will hopefully return a result
indicating auth is complete, so no further retries are necessary and comms
can continue without further worrying about auth until the socket closes.
Further, it then had to associate the authentication token with the socket
itself.

Hope this helps - check out the sspi demos and let me know if you have any
questions (the server side of the authentication dance is almost identical
to the client side, as you will see)

Cheers,

Mark

Subject: [python-win32] Embedding python in a win32 dll and a wx thread
Message-ID: <48508678.39e9220a.4757.ffff9d43@mx.google.com>

Hello everyone

 

It's a big post but I think it's an interesting problem and the result may
become a good recipe for embedding python in many applications in windows.

 

I'm on winxp sp2 using python 2.4 unicode, wxpython 2.8.7 unicode and
vs2003...

 

I'm embedding python in a non opensource financial application which only
lets me to import a dll in scripts which it calls experts. These experts
have three functions: 

 

1-init: which is called when you attach your expert to a chart. 

2-start: which is called whenever a new price (quote) is received.

3-deinit: which is called when you remove your expert from a chart.

 

For embedding python I thought of these 3 steps:

 

-In 'init' I call initpython and startshell from my dll which initializes
python[2], imports wx and starts a shell[3].

 

- In 'start' I send data to python for computation! (not relevant for now)

 

- In 'deinit' I exit wx app[4] and finalize python[5].

 

Everything works fine for the first time (python initialize/shell start/
shell terminate/ python finalize) But after a while I realized that I need
to reinitialize python and start all over again. 

 

The problem is that I have no control over loading and unloading my dll
Which means that the dll stays attached to the application process after
detaching from a chart and somehow it becomes the source of evil the second
time I try to attach it to a chart and I get this traceback[1] in the
pystartshell function when I try to create the wx app. 

 

Whats the problem? If as the traceback says I'm not in main thread why it
works the first time?

The application manual says it detaches the dll from the process when the
expert is removed from a chart. And I check the dllmain detach case and it
was true!!!

Is it the problem of some thread remaining active after finalizing python
(or dllmain detach)? 

How can I know if a thread remains alive after dllmain detach?

Is it usefull to fully unload the dll and the dlls the python loads when I
import wx from memory with win32 api freelibray? I tried it[6] without and
change in results, is it any other way to do it?

 

Any suggestion is welcomed, I'm a newbie, please criticize! I will be the
most grateful person on earth if you guide me!

 

Best regards,

Mani

 

Ps: I tried to attach a 5kb zip file containing the dll source and a mocking
application that produces the same error but I got mail delivery failure. If
you are the angle who is going to help me ;) let me know and I will send you
the source codes via email.

Sadly, Python dies in a number of creative ways with multiple init/finalize
cycles.  I'd suggest simply not even trying to unload Python - just keep a
flag for yourself.  This means it might be almost impossible to ever call
Py_Finalize (calling from your DllMain as you are unloaded is unlikely to be
reliable either) - Windows will cope - but exit hooks and finalizers for
objects which are still alive will not run.  If it is any consolation,
Python is also never finalized when a win32com object causes Python to be
loaded into a process either...

Cheers,

Mark

Message-ID: <1213563888.10852.1258579857@webmail.messagingengine.com>

Wondered if Python could solve this problem:

I have laptop with XP. To adjust screen contrast I hit FN key then F11.
It does not work well - I end up with too little/much contrast - the key
combo does not provide the granularity/fine adjustment I want. There's
no 0-100 bar graph as well. It's probably tied with the ACPI - Advanced
Configuration and Power Interface too which I know very little about -
If I reset the BIOS to defaults, monitor settings seem to go back to
normal.

What I thought of doing was somehow programatically recreate one (1)
FN-F11 keystoke message and see what effect it has. 

Probably complicating the problem is that pressing FN-F11 one rasies
contrast and then pressing it again lowers contrast...

Are there some doable Python methods for this? I'm not a guru but link
me and I'd give it a try.

Thanks,
Lee G.

Message-ID: <f68d89470806160251j3a7897day698edad1af9a5742@mail.gmail.com>

Hello folks,

At work I have to use an MS Access database. Actually it's two
databases (or .mdb files, anyway): One is the "master" file that
contains all the relevant data in tables, and the other one seems to
act a s a "GUI client" which connects to the first one.

Anyway, I have to go through dozens of data records each day, but for
most of them whatever it is I'm having to do could be easily automated
by a script, and that's what I'm trying to do.

Tthe "master" DB resides on a networked drive, and I made a
local copy to test out my script. When this was finished I pointed the
script at the real master, but got the error message below.

According to a password recovery tool I found on the Net

As a workaround you can make a local access database, use link tables
to connect to the remote database, then point your script to your
local database which will then indirectly work on the remote database.

This is, in general, not possible.  The Fn keystrokes are trapped and 
handled by the BIOS.  When one of them does something that a Windows 
driver needs to know about, the BIOS fires some kind of event (like an 
ACPI event).  The Fn keys themselves never get to Windows.  There is no 
"Fn" key in the standard virtual key set, so there is no way for you to 
simulate one.

I suppose that you use "runas" in order to get run in real administrator 
mode.

There are several ways to get an installer run automatically in real 
admin mode :

#1 : the name of the .exe must contain "setup" or "install" keyword. 
This make the UAC detect it as an installer and asks the user for a 
elevation confirmation.

#2 : the .exe must have a manifest that contains :
"""
... (I use the "python.exe.manifest" in which I add the following)
<trustInfo xmlns="urn:schemas-microsoft-com:asm.v3">
  <security>
   <requestedPrivileges>
    <requestedExecutionLevel
     level="requireAdministrator"
     uiAccess="false"/>
   </requestedPrivileges>
  </security>
</trustInfo>
"""


I've put the manifest directly in the .exe using py2exe and :
'other_resources': [(24, 1, mymanifest)],
"24" is where the manifest should be.


#3 Maybe someone could complete here ...?


Hope this helps.

"runas" can actually refer to a couple of things.  One is in the manifest
that you refer to, but another alternative is for your executable to use
ShellExecute, with a verb of "runas" to re-execute itself.

I'm not sure this will work (and I'm not sure if you are saying it does or
doesn't work).  To check it works, you should use the 'mt.exe' tool that
comes with the MSVC compilers and Platform SDKs to check it can extract a
manifest, and it is as you expect.

Yet another alternative is to use mt.exe *after* py2exe has run to embed the
manifest in the final executable.

Note however that it is rare you need the py2exe created executable to run
as administrator - it is the *installer* for the py2exe program that
generally needs this.

> #3 Maybe someone could complete here ...?

Hope the above help.

Mark

Actually this works fine, it was only an idea that you can use to make 
pywin32 installable on XP without service pack :
* on XP it will have the classic behaviour (like with pywin32-210)
* on Vista, user will be prompted for an elevation

I suppose that you don't use py2exe but maybe you can add an embedded 
manifest in your installer.

Is there any attribute in some module I could check to make sure that 
the imported module corresponds to this build? I can't find some sort of 
"global" pywin32 module with this information.

I'm writting safety checks for our build process that verify that the 
installed/imported module of all external software matches an expected 
version string. Example:

   import sys
   if sys.version_info != EXPECTED_PYTHON_VERSION:
     raise Some_error_class

Apart from the fact I screwed up the version number with build 211, there is
a pywin32.version.txt file in the site-packages directory (use distutils to
find that path).  Alternatively, use the win32api file version functions to
get the version numbers from any of the .dll/.pyd/.exe files.

FWIW, here is how Pythonwin's Help->About menu does it:

		# Get the build number - written by installers.
		# For distutils build, read pywin32.version.txt
		import distutils.sysconfig
		site_packages =
distutils.sysconfig.get_python_lib(plat_specific=1)
		try:
			build_no = open(os.path.join(site_packages,
"pywin32.version.txt")).read().strip()
			ver = "pywin32 build %s" % build_no
		except EnvironmentError:
			ver = None
		if ver is None:
			# See if we are Part of Active Python
			ver =
_GetRegistryValue("SOFTWARE\\ActiveState\\ActivePython", "CurrentVersion")
			if ver is not None:
				ver = "ActivePython build %s" % (ver,)
		if ver is None:
			ver = ""

HTH,

Mark

AFAIK, Roger has looked into this a little, and some of his efforts towards
making the win32 modules natively Unicode are an effort towards this - but
I'm not aware of any serious work on this as yet.

There will obviously be 2 sides to this - the .py code and the .cpp code -
running the .py code through 2to3 might be an interesting exercise, and
expose 10 year old code screaming for a cleanup which can be done
independently.  This might mean we might need to get a little more brutal
about which Python versions we support moving forward - eg, is 2.3 and
earlier support still necessary if it costs pain for this transition?  But
in case you can't tell, I personally haven't looked at this at all ;)

Cheers,

Mark

I vote FOR dropping 2.3 and earlier support and moving to 2.6 / 3.0 syntax
as soon as possible.

My reasons for this are selfish... adodbapi is already restricted to 2.3 and
later, since it uses decimal numbers to return SQL data from some numeric
columns. ;-)

Archives of older releases of pywin are kept on sourceforge for those
precious few who are locked into an older python version.


Onward and upward, I say!

Building for Python 3 is going to take a lot of work.  There are many
incompatible changes to the C api (and I'm not even sure they're
guaranteed not to change again before the next release).
The basic layout of python objects has been revised, which will
make it very difficult to continue to build from the same sources,
as can be done now for 2.2-2.6.  Also, the buffer interface has
changed drastically, and Pywin32 makes extensive use of buffers.

As things stand right now, upward is a steep climb.
Dropping 2.3 doesn't really gain us much while we're still
supporting 2.5, which is still the most recent stable release.
Python 2.6 may be useful for transitioning the python code
toward 3.0, but it doesn't help with the C++ sources.

Subject: [python-win32] Embedded Python & win32api
Message-ID: <20080620140132.97380@gmx.net>

Hello everyone,

I'm getting crasy about embedding python-win32 in a c++ application.

PyRun_SimpleString("import win32api") failes with the error message: 

ImportError: No module named win32api.

Every thing works fine if i use the PythonShell.
The problem is not! related to the actual sys.path.

I found the problem x-times on the net but never a solution that works.

If somebody has a solution, thanks in advance!!

Best Regards,
Thorsten

Subject: [python-win32] Capturing a Python script's Task Manager statistics
Message-ID: <1213973865.18018.1259503939@webmail.messagingengine.com>

Anyone know of a way to have a Python script capture its own Task
Manager statistics?

I have a long running Python script whose CPU, memory, disk i/o, and
network traffic I would like to monitor.

An alternative more generic approach would be to run an 'observer'
script that would monitor all Task Manager statistics so I could watch
multiple scripts.

Motivation: I would like to track this script's resource requirements
and if the script detects its exceeding some pre-defined resource limits
for a certain amount of time, to send out an alert.

Any suggestions (or recommendation on a 3rd party that does the same)
appreciated.

Thank you,
Malcolm

Suggestion: Convert it to a service and then you can get at the statistics by 
hooking the Windows Performance Monitor.  Great description of how you would do 
this in "Python Programming on Win32" book.

This is the kind of thing which WMI was probably designed for.
Zenoss [1] uses it, for example, and I have had correspondence
with several people who used my wmi module [2] for this sort of
thing.

One caveat: WMI is basically a uniform layer over the more complex
API. It's *not* the fastest thing on earth and less so when filtered through
a Python wrapper round a Dispatch-based wrapper round the WMI
COM interface. YMMV.

There *are* specific performance classes [3] but often you'll just want to 
watch the attributes for the Win32_Process [4] class (possibly specifying by 
process_id). You can either poll, or you can use the WMI event model.[5][6]

Humph!
For the information of you children, I learned to program in FORTRAN II. My
first hands-on computer was a PDP-8 with 4096 12-bit words of core memory.
It took 15 minutes to boot EDUBASIC into that 4K, since it carried only a
110 baud punched paper tape reader (on a real Teletype brand TTY) for
storage media. If you ever wondered why BASIC was such a stupid language
look what it ran on. Still, it was wonderful to have 5 1/2 digits of
floating point in those days before the scientific pocket calculator was
invented. A great deal of homework was done with interactive mode console
operation, using something like:
LET R = 1.234E-5
PRINT 3.14159 * R * R
(Thanks, Guido, for putting that handy capability into python. I've missed
it over the years.)

But I digress...
Just know that it was a _really_ancient_ geek who said "onward."

Hi!

"children" me?   Thank you !   :o))))))))))))))))))))))))))))))))))

I had started, also, with FORTRAN. On a ICL, with perforated cards.
Then: GAP, XTran, APL, Basic (on Alcyane, very before MS, Apple & Cie).
Then: Texas-instrument, PET (Commodore), TRS-80 (Tandy), Sirius (& Victor), 
IBM, T1100 (Toshiba, the fisrt true laptop), etc. etc.

But, it was at the previous millenium. The future is P3K.

Try setting the "verbose" flag (I can't recall how to spell that via the C
API) and you should end up with info about the paths being searched - that
will help to determine if it is a simple sys.path issue.  If that seems
correct, try starting with 'import pywintypes' - win32api depends on
pywintypesxx.dll - but in general, failure to locate the missing DLL will
result in an error dialog before the import error, and as you didn't mention
that, I'm guessing you didn't see it.

Any serious embedding will want a debug version of Python and pywin32
anyway, so the other alternative is to trace through the execution in a
debug build - eg, set a break-point at an approproate place inside the
import machinery.  You will need to build python and pywin32 from source to
do that, but its not that hard once you have the compiler installed.

Good luck,

Mark

--snip--

I had the same issue.  Here is the sequence I evolved from both 2.2 and 2.5
implementations (and working in production code although this code IS
just at part of the stuff):


// some tables I use
char *plines[]=
{
    "import sys\n",
    "",
    "@",
    "@\\dlls",
    "@\\libs",
    "@\\win32\\lib",
    "@\\win32",
//  my special stuff was here - notably my DebugWin to catch 
// stdout/stderr and pop them up in a tk window
    NULL
};

// a utility function
char *
doubleup(char *input)
{
    static char ans[MAX_PATH];
    char *a = ans;

    while (*input)
	{
	if (*input == '\\')
	    *a++ = '\\';
	*a++ = *input++;
        if (a >= &ans[MAX_PATH-1])
	    break;
	}
    *a++=0;	// ensure 0 termination
    return ans;
}


// the fragment from my main where I set things up
// please note..... not every variable is defined in this fragment!!


	p=getenv("PATH");
	if (!p)
	{
		MessageBox(GetDesktopWindow(),
                              "No PATH found!!!","***** Failure",MB_OK);

	}
	if (strlen(p) >= sizeof(lpath))
	{
		MessageBox(GetDesktopWindow(),"PATH too 
long","*****Failure",MB_OK);
		exit(4);
	}
	strncpy(lpath,"PATH=",sizeof(lpath));

	strncpy(local,StartupDir,sizeof(local));
	_strupr(local);
	if (!strstr(ulpath,local))
	{
		i |= 2;
	}
	// make sure I come first in paths- 
            // otherwise stupid Windoze can't find some DLLs if the are included
	// by other DLLs since the search path is DIFFERENT than that used by 
            //the first inclusion (usually)

	if (i)
	{
	    ulpath[0]=0;
	    if (i & 2)

	    if (i & 1)
	    { // put my local Python dirs at the the beginning of the path!!!!
	    	
strncat(ulpath,"mylocalpath\\Python25;mylocalpath\\Python25\\DLLs;",
                             sizeof(ulpath));
	    }
 	    strncat(ulpath,lpath,sizeof(ulpath));

	    _putenv(lpath);
	}
		
	_putenv("PYTHONHOME=mylocalpath\\Python25");
        _putenv("PYTHONPATH="); // remove from environment - it never worked 
correctly

//using TCL???
	_putenv("TCL_LIBRARY=mylocalpath\\python25\\tcl\\tcl8.4");

IBM 650 anyone? Punched card i/o. 2000 word drum memory ( each word = 10 
decimal digits).
First language: machine language.
Then assembler and a precursor of Basic called Classmate.
PL/I
Then the first breath of fresh air: APL. A lot like Python in that it 
made programming a LOT easier.
On and on ...
Now Python.
Still longing for a way to integrate some aspects of APL into Python.

Numpy is nice, but can't touch APL... 
...of course, it wasn't a challenge to write an obfuscated one-liner in
APL - it was standard practice!

Subject: [python-win32] Querying the VNC Service fails sometimes
Message-ID: <485FB27C.4050405@co.marshall.ia.us>

Hi,

In one of my login scripts for work, I run a query to see if the VNC 
service is running using the win32serviceutil module. The code for that 
I am using looks something like this:

<code>
import win32serviceutil
serviceState = win32serviceutil.QueryServiceStatus('VNC Server')[1]
</code>

This works in 99.99% of cases. However, I have on user that keeps 
getting the following traceback:

Traceback (most recent call last):
  File "\\ourServer\pathName\PostLogon.py", line 207, in ?
    serviceState = win32serviceutil.QueryServiceStatus('VNC Server')[1]
  File "\\ourServer\pathName\Python24\lib\site-packages\win32\lib\win32serviceutil.py", line 479, in QueryServiceStatus
    hs = SmartOpenService(hscm, serviceName, win32service.SERVICE_QUERY_STATUS)
  File "\\ourServer\pathName\Python24\lib\site-packages\win32\lib\win32serviceutil.py", line 81, in SmartOpenService
    name = _GetServiceShortName(name)
  File "\\ourServer\pathName\Python24\lib\site-packages\win32\lib\win32serviceutil.py", line 62, in _GetServiceShortName
    skey = win32api.RegOpenKey(hkey, svc, 0, access)
error: (2, 'RegOpenKeyEx', 'The system cannot find the file specified.')


I used regmon to try and figure out what part of the Registry my code looks at and it appears to be looking for the "DisplayName" value in HKLM\SYSTEM\CurrentControlSet\Services\winvnc

I cannot see a difference in this user's registry versus my own, which does not have this issue. However, I can duplicate the error by connecting to the user's PC's registry using the _winreg module and querying the "DisplayName" value, like this:

QueryValue(key, 'DisplayName')

Which give me this traceback:

Traceback (most recent call last):
  File "<pyshell#14>", line 1, in <module>
    QueryValue(key, 'DisplayName')
WindowsError: [Error 2] The system cannot find the file specified

But if I use use _winreg's EnumValue, I get this:

>>> EnumValue(key, 4)
('DisplayName', u'VNC Server', 1)

What the!? Does anyone have any suggestions? Maybe a better way to get the information? I only need to know if the service is running or not, and if not, to start it.

Thanks!

Well I've no idea if this suggestion will actually work
round whatever the issue is but...

... you can use WMI to query service info. (You knew I
was going to say that, didn't you?)

Example you can modify:

I forgot to mention that we use Windows XP, Python 2.4 and PyWin32 
version 210.

You might want to try build 211.  It uses the API function
GetServiceKeyName instead of manually enumerating the
registry.

However, it sounds like you could have a corrupt registry key.
Try reinstalling the service and see if that helps.

Also check the permissions on the problem users registry.  I would expect
that to cause a different error, but it might be worth checking.

I knew you'd have some idea...you almost always do...I may try build 211 
first since WMI always tends to slow my login scripts down 
significantly. Other than that, WMI is a very cool tool.

Thanks. I'll read up on it and see if I can get it to work on my 
development machine. That way I'll have it for backup if the 211 idea 
falls through.

I keep forgetting that registry keys can get corrupt. I'll try that if 
the 211 idea doesn't work and then I'll give the WMI solution of 
Golden's a go.

Hi! 

Can you try to wrap command-line SC?

Example of command-line : 
    sc query winvnc

Example of wrap:
    def clwrap(commande, cdir='.'):
        import os
        if cdir!='.':    os.chdir(cdir)
        a = os.popen(commande)
        return a.read()

    print clwrap('sc query winsvc')

Good point. Certainly while I do often recommend my wmi
module for things, it is a (Python) layer over a (Python/C)
layer  over an API layer. And none of that's going to make
it any faster.

Most users are local admins. And it's just been happening for the last 
couple of weeks, so it's likely what Roger said: a corrupt registry 
entry. I tried upgrading to 211 last night and am waiting for that user 
to login again. For some reason, after upgrading to 211, I am getting an 
import error on my wx module. Are these tied together in some weird way?

Hi,

I'm trying to connect to database from ASP. I reduced my source to the
following snippet:

<%@ LANGUAGE = Python%>

<%

import sys

for s in sys.path:
    Response.Write(s)
    Response.Write("<br>")

import cx_Oracle

%>
</body>
</html>

After invoking the asp page I get the following result:

Not that I can think of, and build 211 didn't add any funky new import
tricks or anything.  However, build 211 is packing the MFC DLL now, so
*that* could be related - try removing the MFC that is installed in the
site-packages\pythonwin directory.  What does the import error say?

Cheers,

Mark

Subject: [python-win32] FireEvent : comtypes work but win32com fails, why?
Message-ID: <6f80c1520806242158o68df55d4n9cc2f21569bd2dc0@mail.gmail.com>

IE's FireEvent works with a single argument, for example,
FireEvent("onKeyUp"). However, it doesn't work with two arguments :
FireEvent("onKeyUp",event).

But It works without a problem with comtypes.

See the following example to reproduce and compare:


file: c:/temp/javascripttest/onkeyup.html

<html>
<head>
<title>onkeyup</title>
<script language="javascript">
function showmeevent() {
  document.getElementById("here").innerHTML+="[+] "+event.keyCode +"<br/>";
  document.lastKeyCode=event.keyCode;
}
</script>
</head>
</html>
<input id="inp" onkeyup="showmeevent()"/>
<div id="here"></div>
</body>
<body>


Python 2.5.2 (r252:60911, Feb 21 2008, 13:11:45) [MSC v.1310 32 bit (Intel)] on
win32
Type "help", "copyright", "credits" or "license" for more information.
>>> from win32com.client import DispatchEx
>>> ie=DispatchEx('InternetExplorer.Application')
>>> ie.Visible=True
>>> ie.Visible=False
>>> ie.Navigate('c:/temp/javascripttest/onkeyup.html')
>>> ie.Visible=True
>>> e=ie.Document.CreateEventObject()
>>> e.keyCode=65
>>> ie.Document.all.inp.FireEvent("onkeyup",e)
True
>>> ie.Document.lastKeyCode
0

On the html document displayed on the browser I see "0" is appended.
The event object that I created with new keyCode didn't get passed.

Now with comtypes:

>>> from comtypes.client import CreateObject
>>> ie2=CreateObject("InternetExplorer.Application")
>>> ie2.Visible=True
>>> ie2.Navigate('c:/temp/javascripttest/onkeyup.html')
0
>>> e2=ie2.Document.CreateEventObject()
>>> e2.keyCode=65
>>> ie2.Document.all.inp.FireEvent("onkeyup",e2)
True
>>> ie2.Document.lastKeyCode
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Python25\Lib\site-packages\comtypes\__init__.py", line 216, in __geta
ttr__
    raise AttributeError(name)
AttributeError: lastKeyCode

Accessing lastKeyCode from ie2.Document wasn't possible but the event
obejct is passed successfully -- I see 65 appended to the document.


In summary, there are one big problem and one minor problem. The first
is about pywin32's inability to pass FireEvent's second argument. The
second is about comtypes inability to access Document's attributes.

The minor problem is solvable with:

comtypes.client.dynamic.Dispatch(ie2.Document).lastKeyCode

even though I am not sure if this is the right way.

I can't explain that :(  I've stepped through the code, and it seems we are
passing a VT_VARIANT containing a VT_BYREF|VT_DISPATCH.  I'm afraid I'm not
familiar enough with comtypes to know how it is passing that param.

Cheers,

Mark

I still don't know what caused the error exactly, but I got it fixed by 
deleting the wx install and reinstalling it. I did the same with ctypes 
as it was giving me version mis-match issues.

I don't know why I was so absent-minded yesterday. But for completeness, 
here's the traceback:

Traceback (most recent call last):
  File "\\path\to\my\scripts\Utilities\SoScripts.py", line 105, in ?
    import printer_dlg
  File "\\path\to\my\scripts\printer_dlg.py", line 12, in ?
    import wx
ImportError: No module named wx


Thanks for all the tips, guys.

I think that comtypes passes a VT_DISPATCH type in the DISPPARAMS VARIANTARG field.

I would guess that dynamically added attributes can only be accessed via
the IDispatchEx interface. Does anybody know if it is possible to access these
attributes with DispInvoke calls?

comtypes does not (yet?) support IDispatchEx.

That is what I suspected - pywin32 is adding an extra level of indirection.
When pywin32 sees VT_VARIANT, it takes it literally - it supplies a variant
of type VT_VARIANT (ie, the variant itself holds a variant), and that
"child" variant is what holds the real value.  If I understand what you are
saying, comtypes just supplies the variant with the real type directly in
place (ie, a variant with a 'vartype' of VT_VARIANT isn't ever returned by
comtypes).  Is that correct?  If so, I guess I should give that a whirl and
hope nothing else in the test suite breaks ;)

Thanks,

Mark

I do not know where you see the VT_VARIANT.

Here is the IDL defn:

            [id(0x80010452)]
            VARIANT_BOOL FireEvent(
                            [in] BSTR bstrEventName, 
                            [in, optional] VARIANT* pvarEventObject);

and the comtypes wrapper snippet:
    DISPMETHOD([dispid(-2147417006)], VARIANT_BOOL, 'FireEvent',
               ( ['in'], BSTR, 'bstrEventName' ),
               ( ['in', 'optional'], POINTER(VARIANT), 'pvarEventObject' )),

> If I understand what you are
> saying, comtypes just supplies the variant with the real type directly in

Since the is a pure dispinterface, comtypes uses Invoke to call the method,
without doing any parameter conversions - it directly packs the supplied parameters
into the DISPPARAMS rgvarg array.  The 'e2' parameter in the OP's code is a
IHTMLEventObj COM pointer which is derived from IDispatch, so comtypes makes a
VT_DISPATCH variant typecode.

Thats what test suites are for...

Thomas

PS: Do you know the answer to the question that I posted in the other reply to this
thread (short version: does pywin32 use IDispatchEx)?

Yeah - when win32com gets the type info, it is told the variable is a
"VT_BYREF|VT_VARIANT - eg:

	def FireEvent(self, bstrEventName=defaultNamedNotOptArg,
pvarEventObject=defaultNamedOptArg):
		return self._oleobj_.InvokeTypes(-2147417006, LCID, 1, (11,
0), ((8, 1), (16396, 17)),bstrEventName
			, pvarEventObject)

16396, 17 == (VT_BYREF|VT_VARIANT, PARAMFLAG_FOPT|PARAMFLAG_FIN)

so pythoncom's type converter sees this type tuple, and tries to create a
variant with the exact type specified.  It would seem I must treat
VT_VARIANT as a special case (the returned vartype in that case can be
anything and is driven by the type of the param)

I'm more worried that the change will break something that some obscure
program relies on (ie, I hope the test suite shows the change is backwards
compatible)

It doesn't in win32com.client (ie, not when calling objects, as in this
example).  win32com.server does IDispatchEx though (mainly as IE itself is
one of the only IDispatchEx users around.  IDispatchEx was desgined for
ActiveScripting to offer javascript style semantics to an IDispatch-ish
interface.

It's not necessary to do both the PyThreadState stuff *and* the PyGILState
stuff - just remove all the lines I quoted, except for the last, from both
callbacks and things should improve.

What roundabouts would you recommend to make FireEvent work with
pywin32 module? My clients are mostly installed with pywin32, and
switching to comtypes is a risk now.

Subject: [python-win32] How Do You Make Your Speech or SAPI 5 Voices
	Portable?
Message-ID: <001d01c8d785$25b4b080$0301a8c0@brucetower>


Hi!

    I am a visually impaired programmer and just joined the Win32 list to
possibly learn how to make my own screen reader, thus have to learn the in's
and out's of windows. I am sending, attached, a simple version of my voice
package and 2 different test modules. Have not learned all the list
comprehension approaches, but may do so in just this simple package. For it
would come in handy in the Create method at the end of the module.

    I am asking if anyone has played with or used the built in SAPI 5
Microsoft voices and tts engine and or tried to make the voices portable so
they are not required to be installed by the user?

    I also have the eSpeak voices in and they also did not get compiled into
the py2exe package.

    I found out when sending the test to a friend the voices were not there
except the built in voices on there machine. It would be nice to bundle them
into a package so as not to have that person hunt them down. Granted they
could be placed on a CD or a web site for download, but I have not gotten
that far yet and would be nice to do it all in one.

    You can test my module and see if you like it or can use it. The only
one I have not tested yet is the bookmark method. Have not had a need for it
yet, but will soon test it. The Voice2.py is a wxpython module test and
allows you to adjust the Volume, Rate, and Pitch of the voice or voices
installed.

NOTE:
    If you do make an executable you may also after compiling the Voice2.py
get an error if you do not
have MSVcp71.dll, mfc71.dll, and gdiplus.dll copied into your setup.py file.
In other words a copy command to
copy the dll's from your system32 folder. For if you do not, some computers
it
is run on will fail if they do not have those dll's installed. It would
appear
that they are not automatically copied.

    I am assuming that most of you probably have all the C dll's and such
and may not need the note, but those who do not will need the dll's.

#FORCE THE NEEDED DLL'S OR COMMENT THEM OUT!
shutil.copy("c:/windows/system32/msvcp71.dll", os.path.join(os.getcwd(),
"dist",
"msvcp71.dll"))
shutil.copy("c:/windows/system32/msvcp71.dll", os.path.join(os.getcwd(),
"dist",
"mfc71.dll"))
shutil.copy("c:/windows/system32/msvcp71.dll", os.path.join(os.getcwd(),
"dist",
"gdiplus.dll"))

    I hope someone has tried to make a portable voice package, but knowing
that more than 95% of programmers are sighted a may have to search a lot.
But if anyone knows how please let me know.

        Bruce

These DLLs should have been loaded on every Windows XP by Windows 
Update, so anyone with a recent system should have them.

However, that short snippet has a couple of problems.  First, you assume 
that everyone's Windows directory is called "c:/windows".  Second, you 
are copying all three files to the same destination name.  Instead, do 
something like this:

    dest = os.path.join( os.environ['WINDIR'], 'system32' )
    for dll in ("msvcp71.dll", "mfc71.dll", "gdiplus.dll"):
        if not os.path.isfile( os.path.join( dest, dll ) ):
            shutil.copy( os.path.join( dest, dll ), os.path.join( 
'dist', dll ) )

You may think this is nitpicking, and you're probably right, but once 
you start trying to release code into the wild, you have to start 
thinking about the issues you encounter in the strange and magical world 
of the average user.

However, that short snippet has a couple of problems.  First, you assume
that everyone's Windows directory is called "c:/windows".  Second, you
are copying all three files to the same destination name.  Instead, do
something like this:

    dest = os.path.join( os.environ['WINDIR'], 'system32' )
    for dll in ("msvcp71.dll", "mfc71.dll", "gdiplus.dll"):
        if not os.path.isfile( os.path.join( dest, dll ) ):
            shutil.copy( os.path.join( dest, dll ), os.path.join(
'dist', dll ) )

You may think this is nitpicking, and you're probably right, but once
you start trying to release code into the wild, you have to start
thinking about the issues you encounter in the strange and magical world
of the average user.

Hi Tim,

    Thanks for the info, but I was just placing an example. Also, I am
limited to the SP1 for my screen reader program will not work on any later
versions, thus no updates. But I had those dll's from loading other software
and not getting updates. In the end, it was just an example.

    Yes, I am new to this and that example is a good one, but I noticed that
my computer did in fact have the dll, and was not loaded, so why? Well,
py2exe had to be forced to loaded them into the directory from mine, thus my
directory path is that path and was my example

NOW:

    The real issue was my desire to find out how voices from my computer can
be loaded and sent along with my package. So I would need your expertise on
that, for you gave a nice example for the search path, now I would need to
know how py2exe can be told to load voice engines and zip them up with the
program and function at the user end. I have been told about a GUI2EXE but
when downloading that it says it is corrupted. INNO was mentioned as well,
so how would a person package into the final exe to also run the voices if
the other users  computer does not have any tts engine installed?

        Bruce

Hmmm, yes, I responded without fully realizing what you were doing.  You 
should be able to get py2exe to load those DLLs from their original 
locations, as long as it can figure out you need them.

Well, with py2exe, you can certainly load additional files into your 
zip.  In your "setup.py" file, one of the parameters to the setup() 
function is "data_files", which is a list of files to be packed into the 
zip.  Perhaps you could add a quick check at the beginning of your 
script that checks for the presence of a speech engine, and runs the 
installer if it isn't there.

http://sourceforge.net/project/showfiles.php?group_id=65529&package_id=74248

Hi Tony,

    Thanks, but I had used that first. My methods are simple, and essentially identical, but I added the pitch method, for he did not include it. Do not know why, did not ask him, but I am using the SAPI 5 and do a check to see if it is loaded onto the machine. Yet doing that check I do not do anything if the False comes back. 

    I have not added other methods to it, at least not in my test samples. 

    But, the question of most importance is how to have my py2exe also include the wrapper for installing a speech engine if none exist on the destination computer. Which would mean as tim had mentioned, have it pop up an install, which would mean have them go to a link, or have the install in the data folder or as is and run the install. But that means porting in up to 35 megs or more to run the SAPI 5. 
    But having said that from XP on in windows machines the SAPI 5 is installed, but is Vista compatible? For I have heard so many nightmarish stories about Vista, there is no guarantee.

    Anyway, in response to your suggestion, I have pyTTS on my machine, studied there methods, took a look at what the SAPI has and decided to write my own, learn it, and expand on it. To allow a simple speech method for anyone to use. It is not written in C and relies only on SAPI 5 engine methods, along with XML commands.

    In other words a simple speech to plug into anyones program/game.

    So, the engine part may not be an issue except for older machines, I am interested in porting voices only. The eSpeak install is a small install, as is the extra SAPI 5 voices, Mike and Mary are.

    I do no that the NVDA project exists, but when asking them how they do it I was told to learn it on my own.

    In the NVDA project it appears they install up to 4 voice engines, including eSpeak and SAPI, and was wondering how they did it.

    Anyway, I will just keep on asking until I stumble onto the way by accident. Which is what I did when searching for the stream file to use for the save and read of .wav files. It took over 30 searches to find it. I had to just get the search parms exact before finding the needed  format for the file stream in comtypes.

    Now that I found out how that is installed, now I may have found the one Microsoft variable that eluded me when looking at there sapi help. Which means I might be able to write all the commands inside the com types, but have not bothered to yet.

    The pyTTS does not allow you to use a simple name for voices, but eSpeak is as long as Microsoft. But I list the voices in my test sapi file. And when using them I search for the space in the name and default to -1 if not found, but in both cases add one to start at the proper position.

    Time to get moving on, this response is getting too long.

        Bruce

What you probably need is to create an installer for your py2exe project, using something like Inno, NSIS or WiX.  This installer could then include the setup file for the speech engine and ask it to silently install.  Exactly how that would be done depends on the installer you choose and how the speech engine redistributable is package.

Then, your py2exe application can just assume it is there, safe in the knowledge that the installer took care of things.

I hope that answers the question you were asking :)

Cheers,

Mark

Hi Mark,

    It almost does, for I have to look into how the speech setup is handled.
I have a version of INNO installed but have not used it yet. I also have the
SAPI 5 add voices and the eSpeak install, but not SAPI 4 and any other free
source. Will have to look up the description on how to use INNO.

    Since the py2exe was not including the DLL's when doing my setup, I
first had to find out why then get a proper way to include them, which is
what other projects also found out.
    Tim gave me the pointer to the system folder, but gave the reverse
description for the receiving end and not the py2exe end so this is what I
did for the DLL's for the py2exe setup.py includes:
sys_src = os.path.join( os.environ['WINDIR'], 'system32' )
for dll in ("msvcp71.dll", "mfc71.dll", "gdiplus.dll"):
    if not os.path.isfile( os.path.join( dist_dir, dll ) ):
        shutil.copy( os.path.join( sys_src, dll ), os.path.join( dist_dir,
dll ) )

    It works fine now, now on to figuring out the INNO and hope it is screen
reader friendly on windows. Text versions is always the best, I mean text
screen and not graphical screen.

    Thanks,

        Bruce

Welcome to the wonderful world of COM and threading. Basically,
the IWebBrowser2 object which is behind the InternetExplorer
control cannot be passed as such between threads. To pass it
between threads you need to marshal it and pass the resulting 
istream to the other thread which will then unmarshal it again.

There's some sample code below which does this, but you might
want to consider another approach, depending on what your app
is trying to do, such as creating an IE object per thread and/or
passing native Python objects between threads with Queues etc.

TJG

<code>
import os, sys
import threading
import time

import pythoncom
import win32com.client

class Work (threading.Thread):
  
  def __init__ (self, marshalled_ie):
    threading.Thread.__init__ (self)
    self.marshalled_ie = marshalled_ie
  
  def run (self):
    pythoncom.CoInitialize ()
    ie = win32com.client.Dispatch (
      pythoncom.CoGetInterfaceAndReleaseStream (
        self.marshalled_ie, 
        pythoncom.IID_IDispatch
      )
    )
    print "Threaded LocationURL:", ie.LocationURL
    pythoncom.CoUninitialize ()

ie = win32com.client.Dispatch ("InternetExplorer.Application")
ie.Visible = 1
ie.Navigate ("http://python.org")
while ie.Busy: 
  time.sleep (1)
print "LocationURL:", ie.LocationURL

marshalled_ie = pythoncom.CoMarshalInterThreadInterfaceInStream (
  pythoncom.IID_IDispatch, ie

You need the IP Helpers API

http://msdn.microsoft.com/en-us/library/ms886687.aspx

I'm afraid I've never used it, though, so you'll have
to scout around for examples.

New to the pywin32 user list

I've read a couple of articles stating that IE doesn't register with the
ROT.  It was geared toward IE4, but I am not sure if I am running into this
or if I am not doing something right.  I question my syntax because I was
certain it worked once.  Both CreateObject and GetActiveObject take 'progid'
which can be a clsid, or the string representation of the application's
clsid eg. InternetExplorer.Application..

here is what i am trying on xp sp2 ie6-7

from comtypes.client import GetActiveObject, CreateObject

ie = CreateObject('InternetExplorer.Application')

ie.Visible

False

ie.Visible = True

ie.Navigate('http://google.com')
0

(Seems good at this point)

newIe = GetActiveObject('InternetExplorer.Application')

'exception in blah blah'

Windows Error: ( Operation Unavailable )


The same results if I use the seemingly good ie.__clsid

I've also tried passing ie._iid_ and str(ie.__clsid) and str(ie._iid_)

Is this all the same problem with IE not registering with ROT?

Thanks,

Aaron

In short, everything I've come across -- even quite recently --
regarding IE suggests that it still doesn't register itself
with the ROT. You either have to do the EnumWindow / FindWindow
dance and then send keystrokes etc., or pursue one of the
slightly esoteric solutions posted about which involve creating
COM objects to act as proxies for browser sessions. Never done it,
I'm afraid, but it doesn't look any less ugly than any other
COM-based solution I've seen.

Might be worth seeing if the developers behind PAMIE [1] have
already undergone this particular pain.

Hi,

Yup ip helpers the way, but alternatively if u want a simple routine, u 
can launch the netstat -a -b after u createprocess with the appropriate 
flags and pipe the information
to ur buffer, then just parse the buffer and get the information, all 
these can be done without seeing an ugly cmd console popping out. I have 
the whole code in win32 C++ though, maybe there is an equivalent python 
code around.

Marcus.

A loop like the following works for me:

        hr = winerror.ERROR_MORE_DATA
        got = []
        while hr == winerror.ERROR_MORE_DATA:
            hr, data = ReadFile(hPipe, 256)
            got.append(data)
        data = ''.join(got)

I can also make code like the MSDN example work:

            hr, data = ReadFile(hPipe, 256)
            if hr == winerror.ERROR_MORE_DATA:
                t,t,remains = PeekNamedPipe(hPipe,0)
                print "remains is", remains
                hr,d2 = ReadFile(hPipe, remains)
                data = data + d2

But that will cause the second ReadFile to read the rest of the message
regardless of the size.  It should be fairly easy to modify that to a loop,
but I'm not sure what PeekNamedPipe offers in this case (ie, just doing
blocking reads should be fine in this case, as you generally can't start
processing until the entire message is received anyway)

If you keep having problems making it work, please attach your complete
modified test code so we can run it and check it out.

Cheers,

Mark

FWIW, the "COM Browser" in pythonwin enumerates the ROT (and yeah, IE

Hi!

Not a question. Only a little note...  (for readers without Sunday activity)


In (pure) Python, consider this code:
    def ftest():
        vret=(111,222,333)
        return(vret)

    print ftest()     #give:  (111, 222, 333)


In (COM) Python, the same method of the class of a dynamic-COM-server give 
other return:
    def ftest():
        vret=(111,222,333)
        return(vret)

    pv = win32com.client.Dispatch('.......
    print pv.ftest()     #give:  111



In (pure) Python, this code:
    def ftest():
        vret=(111,222,333)
        return(vret,)   #note the comma!

    print ftest()     #give:  ((111, 222, 333),)


In (COM) Python, the same method of the class of a dynamic-COM-server give 
other return:
    def ftest():
        vret=(111,222,333)
        return(vret,)  #note the comma!

    pv = win32com.client.Dispatch('.......
    print pv.ftest()     #give:  (111, 222, 333)


Another detail:
    def ftest():
        vret=[111,222,333]  #list in the place of tuple
        return(vret)

    pv = win32com.client.Dispatch('.......
    print pv.ftest()     #give:  (111, 222, 333)


And, to finish: in COM,  return(vret) & return(vret,)  give the same result.



I wish you marvellous Sunday, with sun, bathe and aperitif.

Misunderstanding about return values:

 >    def ftest():
 >        vret=(111,222,333)
 >        return(vret)


This is the same as: return vret because the outer () are discarded as they are 
superfluous.  You could write return ((((vret)))) and it would do the same 
thing.  It still gets intrepreted as return tuple(111,222,333).

COM obviously treats things differently.

If you have a tuple and want to return it, just return it:  return vret

If you want to wrap objects in a tuple to return it, I would recommend using the 
build in tuple() command as the parenthesis can be confusing:  return 
tuple(111,222,333).

The reason return (vret,) works is because it is the same as: return 
tuple(tuple(111,222,333) (the trailing comma is the key here and is what tells 
python you mean a tuple instead of the "normal" parenthesis meaning.

May seem inconsistent, but I don't believe it really is.

Message-ID: <159697800806300139s117e2449q910afdd64059edcf@mail.gmail.com>

Hey guys,

I am in the process of trying to setup a Python HTTPServer as a Windows Service.

I have a set of scripts that run the web server and a wrapper batch
file, they both work fine when I run them manually.

I used the process outlined at
http://agiletesting.blogspot.com/2005/09/running-python-script-as-windows.html
to setup a Service and added the correct values to the registry.

When I start the service it appears to work but the web server isn't running.

Can anyone offer any further information/advice?

Many thanks
Luke Stedman

Ignore me...have identified the problem....

In the listings given it says that a one of the values under the
Parameter key for the registry entry for the service should be
"AppDir", it should actually be "AppDirectory".

Following on from this, can anyone advise me on solution to
stopping/killing the web server when it is stopped in the service
window?

Cheers
Luke

But maybe those APIs are available in pywin32 ?

Excellent find.
Hmm..i think we might have enough new win32 recipes and content to 
warrant a new book on Python for Windows programming.
The last book was like ...8 years ago? (well ya i know this topic have 
pop-up way too many times)

I'm struggling (in both senses) to find the time to fill in my
new Python-on-Windows site. I'll definitely have a space for
this kind of thing, even if its only a link to a useful recipe.

Well, regardless of his typos, there is clearly at least ONE 
inconsistency here, in that returning a tuple behaves differently in the 
COM and non-COM cases.  Returning a scalar or a list works the same in 
both cases.

I don't know whether that's a well-documented side effect of some other 
process, or if it is a bug, but it is inconsistent.
