I'm unable to find documentation about any COM restrictions imposed on
LocalService and NetworkService.

Nonetheless, how can any such COM restrictions be avoided? For example, with
CoInitializeSecurity().

Subject: [python-win32] Automating Systray Icons
Message-ID: <CAL0E0u6B67i5KDHhceOGwHae4F7O=K9K5RyEizr=+DwRv0Fahg@mail.gmail.com>

Hi All,

I am automating an application in windows using python.

After installation i need to check if the applications icon has appeared in
Taskbar or not. If yes i need to right click the application.

I had been using pywinauto for the same but could not get the job done till
now.

I did the following,

app=pywinauto.application.Application()
hand=pywinauto.findwindows.find_windows(class='Shell_TrayWnd', title=u'')

When i use the handler, get the window and do a right click i am able to
click only in the taskbar and not icons. That maybe because i did not
recognise the icon yet.

Can you guide me how to do the same using pywinauto or pywin32?

Regards,
Krishnan

The issue here is not XP versus Win 7.  The issue here is the Explorer
folder settings.  On your XP system, the user has selected the option to
show the file extensions.  On your Win 7 system, the user has NOT
selected that option.  You're using the GetDisplayNameOf API, which
returns to you the file name exactly as it would be displayed in
Explorer.  When that option is off, the filename "t.txt" would be
displayed as "t", so that's the key you are storing in
name_to_item_mapping.  The key "t.txt" is not found, as the error says.

What you're doing here is a little bit dangerous, because "t.xls" and
"t.txt" and "t.exe" will all return the same value from
GetDisplayNameOf.  You won't get a one-to-one assignment.  Since you
haven't explained what you actually expect this code to do, there's no
way for us to make a suggestion on a better method.

Hi Mark and friends,

for a customer, I had to build pywin32 with VS2010, and when it finally
worked after some changes from https://wiki.python.org/moin/VS2010,
I still could not run

     import win32con

I tried to find out why, to no success. I examined some older 
installation logs
on my machine, and the installation of win32/lib was in fact done correctly.

With the recent setuptools (tested with 1.2.1 and 1.3.2), the 'py_modules'
entry of setup.py seems to be ignored.

After pulling hair until I became almost bald, I ended up with the following
patch to pywin32 version 217 (218 does not work for me, missing files):

Here is the patch if it makes sense to submit it here:

Hi Christian,
   I'm a little reluctant to apply this patch as it stands - we rely on 
setuptools doing the right thing for *all* "library" modules - eg, if we 
need win32/lib/*.py, we presumably would need all other .py files not 
listed here - eg, the entire win32com package, etc.

However, if you can't narrow this down any further, please upload it to 
sourceforge, and I'll see if I can reproduce it next time I make a build.

Cheers,

Mark

Hi Mark,

Yes, I understand very well, knowing the patching dance so much more
than I'd like to...

In fact, 'win32/lib' is a folder, actually the only one which is not also a
package, and exactly this one does not show up in the install logs.

I have the impression that setuptools changed policy about 'py_modules',
if 'packages' is given, too. So I think 'win32/lib' is the only problem 
here, because
it is the only thing that is not a package.

Will try to narrow this down after I am out of my urgent pressure.

What makes me nervous is that nobody else complained so far. Maybe it 
was never
built again for a long time? There are the pre-built installers, but it 
happened to me
that a VS2010 build was needed, and that caused all the grief ...

thanks for your very quick answer -- later - Chris

That makes sense - although it probably also means that .pyc files etc 
may not generated.  I wonder if it might be better to see if we can 
trick setuptools such that we add a dummy package so at least everything 
special it does for packages is also done for these files?

Or maybe we should reach out to setuptools - it might simply be an 
accidentally introduced bug.

Message-ID: <CAJd+stvU7thboNSLK0G8MLf78quv-PohiaOOnYBhmimuYDH+-Q@mail.gmail.com>

Hi,

I am getting the below error while executing the script on one of the
application server.

*WindowsError: [Error 32] The process cannot access the file because it is
being used by another process*

Script used to delete the files from the server.

I had used os.remove(file) and tried with os.unlink(file). But it is giving
me the same error.

Is there any way i can skip the files which can not be deleted and script
proceed further to delete other files or it delete the files forcely
without giving this error.

I know the process which was using the files but i cannot stop that service
because it will impact the application.

Please suggest.

Thanks
Manu Agarwal

Certainly: just catch that particular exception within the loop and
continue.

(FYI os.remove & os.unlink are the same function under the covers)

Hi ,

I caught the Exception using this code:

               try:
                  print(file)
                  os.remove(file)
                  continue
               except WindowsError as e:
                  print e
But i am still not able to delete the files it only caught the exception in
the file and then the script terminates.

Please let me know how can i proceed with the rest of the file to delete.

Thanks
Manu

If the file is in use, you won't be able to delete it. The best you can
do is skip it, log it, perhaps retry or add it to a queue to revisit
later. If some other process is holding it open, there's nothing you can
do -- short of killing that process -- to delete the file out from under it.

In your code above, the "continue" is doing nothing. If you were to put
the "continue" inside your except handler, the loop could carry on, eg.

<code>
import os, glob

for file in glob.glob("c:/temp/*.txt"):
    try:
        os.remove(file)
    except WindowsError as exc:
        print("Could not delete %s because %s" % (file, exc))
        continue
    else:
        print("Deleted %s" % file)

</code>

Yes, there can be a better patch. On the other hand, nowadays there is 
no need
to precompile. If people use it in py2exe or pyinstaller, it will get 
compiled, anyway.
It might be interesting for system-wide installs. But again, most people 
use virtualenv...

Anyway, a minor point for me if you have a better way to trick setuptools.
I agree that this should be discussed with the distutils people. Not 
sure if I
should do that. They broke your project, but nobody cares because the 
builds are there :-)

Please let me know how you will do it. Actually I have one or two other 
things
to dicuss with you...

cheers & thanks -- chris

Sorry for the delay in replying, had a few more important crises to solve.

To summarize, I have a program running under Windows XP, which launches a
process
via os.spawnv(). When the user wants to exit the program they press Ctrl-C.
The program terminates the process via  win32process.TerminateProcess().
Everything is normal.

Running under Windows 7, (using the same version of Python), an exception
is raised when
win32process.TerminateProcess() is called. I know know the reason why


Yes Tim, you're right about this. The external process I was trying to
terminate
with win32process.TerminateProcess() has already been terminated (when
running under Windows 7)

I wrote a short program which duplicated my application and the external
process,
to investigate this issue.

The application launches a process. The process does nothing but count
from 0- infinity.
The count is displayed on the screen 1 second apart.

The application sits in a while loop waiting for Ctrl-C to be pressed.
When I press Ctrl-C, using Windows 7 Task Manager I can see one of the two
python processes
terminate. Print statements in my code tells me it's the external process
which is displaying a count every 1 second.

The things I don't understand are:

1. Under Windows XP, the Ctrl-C does not terminate the process, and
win32process.TerminateProcess() must be called.

2. Under Windows 7, Ctrl-C DOES terminate the process, and win32process.
TerminateProcess()
should not be called.

3. How (and why) does the Ctrl-C get propagated to the process, and why
does it terminate the process, when the process is running in a separate
address space?

Thanks

This is a quick answer to say: unfortunately, Ctrl-C propagation on
Windows within Python itself and between processes in general is a small
nightmare! This is only complicated by the fact that you're using the
CRT spawn which does things under-the-covers to attempt to simulate
Posix semantics -- making it harder to reason about without pretty much
stepping through the code.

Hopefully someone else has (a) more time right now and/or (b) more
knowledge at their fingertips to give you a better answer. If no-one
else comes back I'll try to dig up more information. Ultimately, though,
the answer might be: you'll just have to cope with it!

Message-ID: <CAPbBz_9MrAeNJytGStM-eJC1JYufqOOjf7p5XmdN9BjuEccD1A@mail.gmail.com>

I have a rough service application template [1] that I am using for
multiple projects.  These projects all log to a directory using a date
based logger that is running in a dedicated thread with a queue.  This
allows multithreaded services to properly log and not retain multiple file
handles to the log file.

Every couple days the log rollover fails.  When the logging fails the
current log file is no longer present, and no future log messages are
retained.

Is anyone using the date based logger with Python services in a model
similar to this, or has figured out how to get around this issue?

How is the rollover done?  Close, Rename, Reopen?  Is the log stored on
a network share?  There can be unexpected latencies when doing file
system operations across a network share.  You might consider
eliminating a rename, so that you just close the current log file and
open a new one with the date embedded in the name.

I had a quick peek at the CRT spawn source code, and can't explain why 
it behaves differently on winxp vs 7.  The only thing I can see that 
would explain it is if the second process isn't attached to the console, 
but I can't see why that would be different in the 2 environments either...

As subject line says - current example .xml file is tracks.xml, and sound clips are in /sounds subdirectory, and it uses sound_lib to handle playback:

Are you looking for critique?

With the one exception of blStop in OnEvent, none of your "global"
directives are necessary.  As an overgeneralization, global variables
are bad.  That "lbc.py" module encourages you to think of your
application in a rather non-Pythonic (non-wx) way, in my opinion. 
Usually, almost your whole app would be member functions within a class
derived from wx.Dialog.

Critique is good, and will check out referral to global variable definitions, etc.

Was actually using this initially as looking into processing XML file parsing, initially, and then just played with it, and, I generally just use the LBC module since it's the simplest/easiest way for me to generate layout quickly and easily, but, know should look into wx itself in more detail/depth.

Stay well

Oh yes, and considered class implementation, but, haven't bothered as of yet, since, like said, this was actually more of a form of testing/trying out XML parsing to start off with.

Also, presume with regards to global keyword usage, while it may not always be required/necessary, unless you want to be 100% sure referral to something like that blStop, sort of boolean switch variable is definitely referring to correct object/element, I was maybe also just being careful, but, will have a look around for a bit more documentation regarding this side of it - sorry, but, python is also sort of like my secondary platform, so am definitely not perfect in my workings with it as such...<smile>...and, things like the blStop switch variable are generally the type of thing would try use if was running something like the playback routines in another, background thread process, or something, instead of how this one is currently operating.

Stay well
