I have been using PythonWin2.4.1 (#65, Jun 20 2005, 17:01:55) [MSC v.1310 32 bit (Intel)] on win32 for nearly one year. Yesterday I added Python for .Net (Python 2.3.4 #53 May 25 2004). Now some of my old code (originally written some years ago on a Unix platform and which worked unmodified with PythonWin) does not work. Here are two illustrations:

1. No module named _sre
2. from os.path import (curdir,
                                    ^
SyntaxError: invalid syntax

Please advise.

Subject: [Python.NET] Locking Issues
Message-ID: <44E306F6.9080307@statictype.org>

Hi,

I've got some code in C# that embeds python as an interpreter using 
Python.NET.
This code executes various python scripts to calculate values and 
returns. I'm calling AcquireLock() and ReleaseLock() before and after 
each use of the PythonEngine. The code works flawlessly in a WinForms 
test app. But if I try to run the code from an ASP.NET web application 
or a web service, sometimes, the call to AcquireLock waits 
indefinitiely. Stepping through a debugger shows that first time I call 
it, it works, and then ReleaseLock() also works. But then a second call 
to AcquireLock hangs. This problem is only there if I execute the code 
from a web application.
Is this a known issue?
Is there any work-around for it?

If its a bug in the Python.NET code, then maybe I can look at possibly 
fixing it.
Or could it be a fundamental problem with the Python interpreter itself?

Thanks,
Haran

Subject: [Python.NET] Installation on existing Python2.4
Message-ID: <20060819184451.54503.qmail@web35405.mail.mud.yahoo.com>

I want to run Python.Net from within my existing Python 2.4 environment. 
I installed with pythonnet-1.0-rc2-py2.3-clr1.1.exe 
I chose to add .NET awareness to my existing Python environment at installation. (Not quite certain what that really means.) 
I was already running Python 2.4.3 (#69, March 29 2006, ... 
I had previously installed the following .NET packages from Microsoft: 
    Microsoft .NET Framework 1.0 				Hotfix (KB887998) 
    Microsoft .NET Framework 1.1 
    Microsoft .NET Framework 1.1 				Hotfix (KB886903) 
    Microsoft .NET Framework 3.0 
    Microsoft .NET Framework 2.0 
    Security Update for Microsoft 				.NET Framework 2.0 (KB917283) 
    Microsoft .NET Framework 2.0 				SDK - ENU 
 			 		 	   
 Python 2.4 is installed at c:\python24
Python.Net is installed at c:\Program Files\PythonNet

I can run the "Python for .NET" console
I can execute the demo programs using the Python 2.3.4 that the Python.Net installer provided.

I copied CLR.dll and Python.Runtime.dll to c:\python24, but 

    >>> import CLR

results in 

    An unhandled exception of type 'System.DllNotFoundException' occurred in Python.Runtime.dll

    Additional information: Unable to load DLL 'python23': The specified module could not be found. (Exception from HRESULT: 0x8007007E)

as reported by the Microsoft CLR debugger.

In Python 2.4 my path is:
    C:\WINDOWS\system32\python24.zip
    C:\Python24
    C:\Python24\DLLs
    C:\Python24\lib
    C:\Python24\lib\plat-win
    C:\Python24\lib\lib-tk
    C:\Python24\lib\site-packages
    C:\Python24\lib\site-packages\win32
    C:\Python24\lib\site-packages\win32\lib
    C:\Python24\lib\site-packages\Pythonwin

I copied CLR.dll and Python.Runtime.dll to c:\python24\DLLs and renamed CLR.dll to clr.dll.
I then get the following:

    >>> import clr
    Traceback (most recent call last):
      File "<stdin>", line 1, in ?
    ImportError: dynamic module does not define init function (initclr)
    >>>

Can anyone tell me what I should try next?

Before you continue, consider to install version built for Python 2.4

That worked. Thanks.

I hadn't seen the 2.4 version when I downloaded via SourceForge. There the "Latest File Releases" section is showing the 2.3 release. When I clicked the "Download" button in that section I was only presented with download options for the 2.3 release. The 2.4 release is further down on the first page, but it was off my screen and I did not scroll down far enough, not knowing it was down there.

Thanks again.

Hello, new to this mailing list & PythonNet, so forgive me for asking
questions others may have already asked. 

I am using 1.0-rc2 downloaded from sourceforge, which as I understand
only supports .NET 1.1, however having built a simple assembly in .NET
2.0, I didn't have may issues using it.  

Is it safe to use this release with .NET 2.0( provided I don't need
access to features introduced in 2.0 )

Hi Maksim ? it is safe to use it, you just won?t have access to 2.0-only
features like generics, etc.

The latest in svn mostly supports generics and a number of other 2.0-isms,
but I haven?t had any time to make a release or do much on it lately.

Subject: [Python.NET] Loading "System.Data" assembley
Message-ID: <8674D71026D5C848831DB7CA34B1C75803CFF7@fds1wmail01.funddevelopmentservices.com>

Calling Assembly.LoadWithPartialName( 'System.Data' ) seem to be
silently failing and not making System.Data namespace available.
However, loading another assembly which in turns loads system.data seems
to work.  Has anyone seen this before?  Also tried loading with full
name.

		See Example Below:
		Fails
		#Assembly.LoadWithPartialName( 'DevExpress.Utils.v6.2' )
		Assembly.LoadWithPartialName( 'System.Data' )
		from CLR.System.Data import DataSet

		Works
		Assembly.LoadWithPartialName( 'DevExpress.Utils.v6.2' )
		#Assembly.LoadWithPartialName( 'System.Data' )
		from CLR.System.Data import DataSet
