I use the "DirectX 9.0 SDK Update (Summer 2003)" documentation.

This C# sample is very close to my code. It use the same constructor.

Is there any way to view the constructor signature with python ?

Not currently, though I've put it on the todo list (I think I can have SomeClass.__doc__ display constructor info). Your code _looks_ right, which makes me suspect that the Python integration layer is somehow mishandling one of the arguments. I don't have managed directx handy, so I don't have a quick way to check that theory :( If you're inclined, you can probably hack the MethodBinder.cs file to log what it's doing when it tries to convert the arguments. I'll try to get mdx installed to try to reproduce it myself, but it may be a few days. Just to be sure - you are using the latest beta, right? Beta 2 had a bug that caused problems calling ctors, so make sure you are using the b3 release. Brian Lloyd brian@zope.com V.P. Engineering 540.361.1716 Zope Corporation http://www.zope.com
