You'd hit the same limits with 1gb of physical RAM, as long as you had a large enough swap file. There are two limits on an individual application, the amount of swap space, and the amount of address space. Swap space management depends on which "windows 32 OS" you're running, and how you have it configured. I will have to assume you mean one of Windows XP, Windows Vista, or Windows 7. And that swap space is shared among all the applications currently running. But I expect you're bumping into a virtual address space limitation. Even if you could have a 50gb swapfile, that would raise the number of large applications you could run (very slowly), but not the size of any one application. Your address space is 32 bits, or 4 gigabytes. Every pointer in your program, or in the system has to point to a unique place, so there are only 4 gigabytes of virtual space. By default Windows reserves the upper half of that for system DLL's, device stuff, and working space. It also reserves the bottom meg or so for mostly historical reasons, and to catch null pointer errors. So you only get 2gig of space for each process. Two ways of extending that. There's something called PAE (and AWE ), which allows you to read and write things "above" 4gb, but I don't know anything about how it may be accessible from Python. Certainly you couldn't store ordinary python objects there. Think of it as a (probably) fast disk partition with special read/write methods. But the one you might want is a boot.ini option that tells the OS to only reserve 1gb for itself, and leave 3gb for user space. But there are tradeoffs, including the need to modify an application's executable to take advantage of it. And the whole system may run substantially slower, even when your're extended app isn't running. See links: http://www.microsoft.com/whdc/system/platform/server/PAE/PAEmem.mspx http://blogs.technet.com/askperf/archive/2007/03/23/memory-management-demystifying-3gb.aspx Bottom line? If you really need more than 2gig of user space, probably you should go to a 64 bit OS.

OK; just tried it and I see what you mean. In my case, I'm using one of those card readers with four different-sized slots. It "pre-registers" as four drives so you don't get any further device change events. (I assume this is comparable to what you're doing...) All I can suggest is that you watch the Win32_DiskDrive instances with an InterfaceType of "USB" for a modification event and check whether the MediaLoaded has changed. Something like this:


import wmi

c = wmi.WMI ()
watcher = c.Win32_DiskDrive.watch_for (InterfaceType="USB")

while True:
   try:
     disk = watcher (timeout_ms=10000)
     print disk
   except wmi.x_wmi_timed_out:
     pass

If you know which device id will always be firing (eg the only slot I can use is PHYSICALDEVICE3 then you can build that into the query. > There's an interesting document attached which shows some potential >C++ code; but I'm in a little out of my depth here - "help"! About half of that is basically the code I posted here: http://local.timgolden.me.uk/python/win32_how_do_i/detect-device-insertion.html The other half deals with the case where you want to use this sort of technique but where you're in a service or otherwise don't have a top-level window. If the WMI stuff doesn't work for you and you need this kind of thing (and don't have/want a top-level window) then we can try to run something up on the basis of the article.

This saves work on each installed PC, and also avoids needing to have the typelibs included on each target PC (the usually will be available, but depending on a number of things, may not be) * Tell py2exe to avoid including anything in the win32com\gen_py folder. If no such folder exists as win32com initializes, it will use a folder under %TEMP% for this purpose - but if it does exist - even inside a read-only .zip file or in a read-only directory - it blindly tries to use it. As you are seeing, this will fail for stuff installed under "Program Files" - you need elevated permissions to write there. The first is the best general option - you don't have to rely on writing anything anywhere to achieve something which works (but it isn't clear you are using py2exe - so while that specific advice may not be applicable, the general idea is (ie, ship with a pre-populated win32com\gen_py folder) HTH, Mark From mail at timgolden.me.uk Sun Feb 14 10:41:01 2010 From: mail at timgolden.me.uk (Tim Golden) Date: Sun, 14 Feb 2010 09:41:01 +0000 Subject: [python-win32] USB Insertion Extrinsic Event exists?

We've kind of tried before and: not really. There's nothing to stop them going on the Python Wiki. For some reason I rarely go there myself, but I imagine people do, and at least it's Googleable under "site:python.org". I tend to put things on my own site (timgolden.me.uk/python) or to post them to my blog. Having seen the stuff you've been doing, I'd be very keen to see a write-up and examples. I'm perfectly happy to chuck them up on my site if you find no better place, but it's a manually-maintained set of static HTML so perhaps not the best... Wherever you end up putting them, I'm certainly ready to add a link to my "How-Do-I?" series to point there. Or start something new and see if it flies.

Well I've given it a go and, naturally, it works ok. Except... As documented(ish) (look under Remarks): http://msdn.microsoft.com/en-us/library/aa363431%28VS.85%29.aspx It'll only handle DBT_DEVTYP_DEVICEINTERFACE or DBT_DEVTYP_HANDLE That wouldn't matter too much since the device interface event returns the name of the volume, which one can use to good effect. Except... The pywin32gui_struct library which parses the stuff coming back from the events assumes that the string is NUL-terminated. But it's a UTF16 Unicode string so it's "nul-terminated" after the first byte. I'll raise this as a bug on the pywin32 tracker, but meanwhile I'll try to get an example which works around it by parsing the header manually, as per the windows message example. Or I could monkey-patch the win32gui_struct module. Might be easier.

Yes, it's possible to create an object in your C code, then add attributes to it one by one to match your structure, but the code to do so is rather tedious. In my opinion -- and it is only my opinion! -- you're better off using a Python wrapper to create and populate the object. Have you encountered the "swig" library? Swig can read C header files, and generate C and Python code that exposes the structures and function calls to Python. If you need to do this a lot, it might be worthwhile to learn about it. It is a difficult tool to learn, but once you get it, it's incredibly handy. Much of PyWin32 is automatically generated by swig (with careful tweaking). http://www.swig.org/Doc1.3/Python.html -- Tim Roberts, timr at probo.com Providenza & Boekelheide, Inc.

The behaviour is: 1. On Windows 2000 and XP, function works as expected, returning with a 0 errorcode as soon as the dial-up connection is made. 2. On Windows Vista and an un-updated copy of Windows 7RC1, the connection is made (as can be seen on the flashing LEDs on my modem and the ipconfig command), but the Windows API takes almost 40 seconds to realise this, which only then returns a 0 errorcode. 3. On that same Windows 7RC1, after running an update, as well as on a full Windows 7 installation, the connection is made (again according to the flashing LEDs on the modem and the ipconfig command), but after 60 seconds win32ras.Dial() still hasn't returned. If I send a win32ras.HangUp(), Dial returns with error 621, which is to be expected if you interrupt a Dial command. Has anybody else experienced something similar? Or does anybody use win32ras.Dial under Windows 7 without issues? Is there any known bug related to this?

Well, at the risk of being flippant, it seems to me that the right thing to do is to change the default printer to print to PDF. By hand. Assuming you have Acrobat installed, go into Settings, Printers and Faxes, right-click on Adobe PDF and select "Set as Default Printer". It would be very unfriendly for you to have your script change the default printer. Users do not expect that. -- Tim Roberts, timr at probo.com Providenza & Boekelheide, Inc.

You can do it when you add the column using LVM_INSERTCOLUMN, or you can do it afterwards by sending LVM_SETCOLUMN. You set the "fmt" member of the LVCOLUMN structure to LVCFMT_RIGHT or LVCFMT_CENTER. Be sure to set LVC_FMT in the "mask" member to indicate that you're changing the format. If you use LVM_SETCOLUMN, you should probably do an LVM_GETCOLUMN first, then modify the current settings. The leftmost column is ALWAYS left-justified. This cannot be changed.

I tried TK: limited. I tried wx: I let down, because several conflict's versions, and it is very complicated. Actually, I use Autoit like GUI, and Python's functions linked to UIobject and events (via COM) ; run OK, but not pythonic. Also I use IE like GUI, with PLUIE (http://ponx.org/ponx/guiescreens.htm) ; but it is not very fast. I think than a pure pywin32 is a good way to explore. Have a nice day.

The services load C++ DLLs, for example snap.pyd, to do some of the work. All working fine until a customer installed pywin32 build 214 then some of the services don't load, because some of the DLLs load others do not :( The error I get in the Windows Event Viewer looks like this Python could not import the service's module Traceback (most recent call last): ... import snap ImportError: DLL load failed: Invalid access to memory location. %2: %3 The DLLs load fine in PythonWin and if the .py file which includes the import is run from the command line. The .py file only fails if run by PythonService.exe. If there is someone out there who can say "yes that's because you have not done .... " that would be wonderful. Otherwise is there a list of the changes from build 212 which could break existing applications so that I can work out what I've got to change ? I hope this has all made some sense Thanks Tim. ------------------------------ Python Automation Question DISCLAIMER: This e-mail, and any attachments thereto, is intended only for use by the addressee(s) named herein and may contain legally privileged and/or confidential information.

You can do it when you add the column using LVM_INSERTCOLUMN, or you can do it afterwards by sending LVM_SETCOLUMN. You set the "fmt" member of the LVCOLUMN structure to LVCFMT_RIGHT or LVCFMT_CENTER. Be sure to set LVC_FMT in the "mask" member to indicate that you're changing the format. If you use LVM_SETCOLUMN, you should probably do an LVM_GETCOLUMN first, then modify the current settings. The leftmost column is ALWAYS left-justified. This cannot be changed.

I tried TK: limited. I tried wx: I let down, because several conflict's versions, and it is very complicated. Actually, I use Autoit like GUI, and Python's functions linked to UIobject and events (via COM) ; run OK, but not pythonic. Also I use IE like GUI, with PLUIE (http://ponx.org/ponx/guiescreens.htm) ; but it is not very fast. I think than a pure pywin32 is a good way to explore. Have a nice day.

At logon event the service reads a configuration stored on the PDC and get some rules to apply depending on : * the computer name * the user name and/or groups I don't know what details I could give about what to do with.

I don't see anything immediately wrong with this. The doc says that that the bitmap must not be selected into a DC at the time of the call, but the sample application doesn't follow that, and when I selected hbmOld back into memDC it didn't change anything. FWIW, you can replace venster.gdi.GetDIBits with ctypes.windll.gdi32.GetDIBits with the same results and use one less module. There are a couple of alternatives. After you do the BitBlt, you can call GetBitmapBits to make a copy of the bits. That's quicker than GetDIBits, and as long as you're running true color (which everyone is today), it's the same end result. Alternatively, you can call GetObject on the hbm, which returns a BITMAP structure. The bmBits member contains a pointer to the bits (which you'd still have to copy). -- Tim Roberts, timr at probo.com Providenza & Boekelheide, Inc.

I'm wondering why would you expect that. Python doesn't know anything about specific window messages. A window message consists of a handle, a message number, and two integers. The interpretation of those two integers is entirely dependent on the message number. The wrapper just hands them off to you for interpretation. > ...but > print lParam > returns values like "1236036" (the type is "int"). > That looks like a memory address to me, Yes, that's 0x12DC44, which is in the heap. > but I am not sure.

Thanks! This also works. I am now using the following solution

extr = '@' + 'l'*wParam
bytes = struct.calcsize(extr)
parts = win32gui.PyGetMemory(lParam, bytes)
parts = list(struct.unpack(extr, parts))

Thanks. This works! I was experimenting with ctypes before, but using 
different methods (the from_address function) and that resulted in 
crashes. But your solution works.

Message-ID: <3d26fb441002260616n6f592823xcb8c91e591dacc45@mail.gmail.com>

Hi,
I'm trying to process large amount of autocad drawings by python
script using DWGDirect library (but I think I already saw the same
problem with original autocad automation with python). I'm trying to
explode the block in drawing and this action leads to delete the
original block from drawing. But the block object is still linked with
python object:
block = oDoc.ModelSpace.InsertBlock(....)
block.Explode() #this operation exploding the block to its elements
and removes the block from drawing
->Win32 exception occurred releasing IUnknown xxxx...

I think it is not possible to change the way how the Explode()
function work. Unfortunately, this exception frequently end by python
crash and I cannot catch the exception by try...except.
So, Is there any possibility to avoid this exception, or catch the exception?

Thank you

Message-ID: <4B87E71F.2010007@co.marshall.ia.us>

Hi,

I have been tasked with trying to find a way to query the peak commit 
charge of our various workstations. It would be great if I could do it 
remotely, but logging is also a possibility. Unfortunately, my Google 
skills have failed me as I can't find anyone else who is doing this 
publicly. Do you guys have any hints for how best to approach this task?

Here's the use case: We are using Sun Ray virtual desktops and are 
trying to figure out how much RAM each VM is using. We are trying to 
decide if we can shrink the allocated amount of RAM of if we should just 
upgrade the servers.

Thanks,

- Mike

There is simply no mechanism in Windows to provide this information.  It
requires either API hooking or a file system filter driver, both of
which are well beyond the scope of this mailing list.

We're using ReadDirectoryChangesW to catch changes; I have no idea
whether that would give the info you want.

Deleting the object and object instances allow the other applications to

No, I think you have your answer.  You will have to delete the objects
after every access.  I would call this a design flaw in the COM object,
but at least you have a solution.

Maybe look into the win32pdh/win32pdhutil modules?

'Fraid not; I assume that that is the "Tim Golden's script"
the OP is referring to, but that only handles *updates* no
opens/reads. As Tim R points out, there's really no way to
do this in Windows without dropping down to the device-driver
kind of level.

You can use the file's SACL to create an audit record in the event log
whenever the file is accessed.
\win32\Demos\security\set_file_audit.py has some sample code
for SACL's.

Subject: [python-win32] Catch system level events in python
Message-ID: <201002281507.05287.jan@janschneider.net>

Hi,

i am developing a windows service using python-win32.
Now I am searching for a possibility to get a notification when a user is 
trying to shutdown the system.
In certain cases I need to cancel this shutdown,
Does anyone knows how this could be done?

Is it possible to catch system level events in python like in other 
programming languages as for example C#:
http://mail.python.org/pipermail/python-win32/2008-January/006645.html

Thanks,
Jan
