Subject: [Python.NET] embed Python in C#
Message-ID: <SNT101-DS10B2577BFC58D9A034B297C49B0@phx.gbl>

Hello all,

After following some examples around the web, and some discussions in the mail list,
I came into the following snippet to call a function defined in a Python script into a C# host app,
as seen at ?http://mail.python.org/pipermail/pythondotnet/2007-June/000620.html?:

//
public static void MethodThatCallsPython()
        {
            // have to acquire the GIL to safely call back into Python!!
            IntPtr state = PythonEngine.AcquireLock();

            PythonEngine.RunSimpleString("print 'hello'");

            // done using python for now, so release the GIL...
            PythonEngine.ReleaseLock(state);
        }
//

Although it looks quite simple, VS2010 this throws an exception at the very first line of code:
?Attempted to read or write protected memory. This is often an indication that other memory is corrupt.?

My machine runs Windows 7 64-bit, and as I read somewhere else, 64 bit OS may be a matter of concern.
Does anyone know how to overcome this annoying situation??

Thank you for any help provided!

Python for .NET has a huge amount of carnal knowledge about the in-memory
layouts of python objects etc., and I don?t know that anyone has tried to
port 
it run with 64-bit :(

Subject: [Python.NET] This assembly is built by a runtime newer than t he
	currently loaded runtime
Message-ID: <loom.20100817T100716-403@post.gmane.org>

I needed to access .NET dlls compiled for .NET4 and ran into the error:

System.BadImageFormatException: This assembly is built by a runtime newer than t
he currently loaded runtime and cannot be loaded. (Exception from HRESULT: 0x801
3101B)

So I attempted to recompile PythonDotNET for .NET4. In VS2010 I changed all the
project targets to be .NET4 and it compiled fine with only a couple of errors
about System.Security.Permissions.SecurityAction.RequestMinimum being obsolete.
Unfortunately when I tried to import clr I got the following error:

SystemError: dynamic module not initialized properly

Looking further into it I found that in buildclrmodule.bat lines 33 & 66
referenced the .NET2 idalsm.exe:

%windir%\Microsoft.NET\Framework\v2.0.50727\ilasm /nologo /quiet /dll
%ILASM_EXTRA_ARGS% /include=%INCLUDE_PATH% /output=%OUTPUT_PATH% %INPUT_PATH%

I changed this to reference the .NET4 version:

%windir%\Microsoft.NET\Framework\v4.0.30319\ilasm /nologo /quiet /dll
%ILASM_EXTRA_ARGS% /include=%INCLUDE_PATH% /output=%OUTPUT_PATH% %INPUT_PATH%

...and everything works perfectly!

HTH,
Dave

NB: Apologies if this appears twice - I sent it from a different account
previously and don't think it made it through.

This afternoon I uninstalled Visual Studio 2010 from my laptop and
re-installed Visual Studio 2008, then rebuilt "Brandon.dll", in the
hopes that 2010 was simply too recent a version of Studio to be using
with the c:\python26 from the python.org page.  Sadly, I was wrong; I
still get the above error when trying to import the DLL.

Summary: Add info parameter to the this.Bind() call

Initial Comment:
I've added the info parameter to the call to the Binding binding = this.Bind(inst, args, kw, info) call to take advantage of Bind()'s ability to use a single MethodBase (CI or MI).
