Could anyone give some pointers on getting Python.NET running on Mono
(Linux)?  Any help would be appreciated.

Hello,

I'm trying to figure out how can I use Python.NET, and I'm having weird
problems:

This run ok:

<script language="C#" runat="server">
void Page_Load(Object sender, EventArgs e) {

  PythonEngine.Initialize();
    
     PyObject p = PythonEngine.ImportModule("sys");
     PyObject c = p.GetAttr("path");
     

     string s = c.ToString();
     Response.Write(s);

     
     PythonEngine.Finalize();
}

</script>

It outputs:
['D:\\testsite\\bin\\python23.zip', '.\\DLLs', '.\\lib',
'.\\lib\\plat-win', '.\\lib\\lib-tk',
'\\\\?\\C:\\WINDOWS\\Microsoft.NET\\Framework\\v1.1.4322']

But when I'm trying to run the script foo.py which is located under the
above '\lib' I'm getting "Exception of type
Python.Runtime.PythonException was thrown." at the line:

PyObject p = PythonEngine.ImportModule("foo");

How can I learn more about the exception cause?

Thank you,

Hi Laurian,

Try removing the call to PythonEngine.Finalize(). That should 
_only_ be called when you are truly finished with the Python 
interpreter (to clean up and free resources, etc.) That method 
tears down the Python runtime environment and after it is called 
you can't use Python anymore from any thread in the process.

Hi Matthew - 

Last time I tried, I couldn't get it working on mono due to some 
missing bits in the mono reflection and interop layers (both of 
which Python.NET exercises pretty extensively).

That was probably 6 months ago though, so hopefully the situation 
is better now. I'd be interested to hear if anyone on the list 
has tried running under mono recently, and what the results were...

I'll certainly give it a shot when I get home.

The issue was with sys.path which when called from aspx, and not from an
exe was relative (.\lib, instead of d:\testsite\bin\lib) so I have to
set it like this before importing my module:

PyObject sys = PythonEngine.ImportModule("sys");
     PyObject path = sys.GetAttr("path");
     PyObject append = path.GetAttr("append");
     PyObject[] a = new PyObject[1];
     a[0] = new PyString("d:\\testsite\\bin\\lib");
     append.Invoke(a);
     Response.Write(path.ToString());

Another issue, if I tear down the python runtime environment (not by
several finalize(), but by recurrent errors) how can I restore it
without restarting my application (in ASP.NET it seems I have to restart
the WWW Publishing service for this)

Thank you,

Subject: [Python.NET] Calling DLL functions?
Message-ID: <40A655E5.1050500@email.unc.edu>

Hi,

Is it possible to call function in DLLs using Python for .NET? The 
reason why I ask is that I'm working with Accessibility assembly. This 
assembly defines the classes and interfaces for the Microsoft Active 
Accessibility library which allows a program to inspect the interface 
object model of other programs at runtime. However, the functions for 
performing the actual inspection are located in oleacc.dll. These 
functions return instances of the objects defined in the assembly.

I'm pretty new to .NET programming so I might not be explaining this 
very well. Any help would be greatly appreciated.

Thanks,
Pete

Knowing what little I know of Python for .NET I would say that you might 
want to look into ctypes.  I have used it very successfully to do call 
arbitrary functions in DLLs.  See 
http://starship.python.net/crew/theller/ctypes/ for more information.

Just to clarify - is oleacc.dll an unmanaged (native) dll or a 
managed (.NET) dll?

Hello!

PythonDotNet is very imporessive.
I was very excited seeing it working with .Net classes.

My question is that how I can import classes(namespaces) that I made in C#.
In C#, I give a compile option for the dll that I created.
How can I do it with Python?

Thanks.

Hi Sam - generally, if you have created an assembly named 'A.B.dll', and the
name of the assembly matches the namespaces it contains ('A', 'A.B'), then
you
should just be able to do:

from A.B import SomeClass


...after making sure that A.B.dll is on the python path.

Hope this helps - the readme.txt that comes with Python for .NET goes into a
bit
more detail, if you haven't seen that already.
