Re: [Python.NET] System.InvalidOperationException: Handle is notinitialized

25 Apr 2009

      Maksim,
Thanks for you reply. Yes, I have tried that and it also crashes (without
spitting out any errors) when I do that as well.
output:

-------------Start copy from console--------------
...
...
...
import clr
s = System.String("some string")
H:\>
-------------End copy from console--------------

I think the problem has to do with the fact that python.net is optimized for
python2.5, but I am trying to use it with 2.6. Is anyone using
python.netwith Python 2.6. If so, can you email me any changes you
made to the
python.net code before compiling, and a precompiled dll to check against?

thanks,
-Ethan

Ethan,
    I believe [] syntax is meant for generics.  To create string s =
System.String(“some string”) should work.

If I try s = String("a") without the [str], it doesn't even give an error,
it just quits.
I spent a few minutes looking through the archives before posting, but I
did not search exhaustively, so if this is a redundant post, I apologize.
thanks,
