Re: [Python.NET] Accessing Public Functions in Module

18 Dec 2007

      Thanks.  I downloaded a reflector from:
http://www.aisto.com/roeder/dotnet/

By using that I could see that the module in question was declared 
friend (default, if not specified.. I guess), not public.  I made it 
public and can now access the functions within it.

So the compiler didn't mangle anything, it was just me not knowing what 
I was doing :).  But your idea worked anyway.

Thanks again.

Most likely the vb.net compiler does some shenanigans and places this
(in the IL) in a place that might not be obvious (like a generated class).
If you use reflector on the assembly you can probably discover what its
real name is and try to import that from python.

Can you access these same functions in C#? Maybe what you have to
    do is write a wrapper library for your VB.NET library in C#, and
    have Python access the library through the the wrapper.

We have an application that was developed in Visual Basic, and

        like to use Python for .NET to extend it.  I've played around
        with it a
        bit, and everything works fine if it is within a class in the
        .Net assembly.
However, there are a number of components that exist as public
        functions
        within a module.  I cannot seem to access them from Python for
        .NET.
My latest session is shown below, where I try to import and
        use the
        function, "NonQuery" within the module, "SQL_Module" to no avail.
Thanks for any help, and thanks for this wonderful piece of
        software.  I
        can't wait to start programming some things with this instead
        of Visual
        Basic.
