Loading "System.Data" assembley
by Maksim Kozyarchuk 31 আগস্ট, 2006

31 আগস্ট, 2006

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 Maksim

Re: [Python.NET] Installation on existing Python2.4

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.

Installation on existing Python2.4
by Steve Dewey 19 আগস্ট, 2006

19 আগস্ট, 2006

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?

Locking Issues
by Haran Shivanan 16 আগস্ট, 2006

16 আগস্ট, 2006

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

no module name _sre

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.
