Re: ctypes.windll.kernel32.GetProcAddress returns address of 0

I found the DirectX type library dx7vb.dll in the DirectX 7 SDK. 
(Also, dx7vb.dll from the DirectX 8 SDK can be downloaded here: http://www.thevbzone.com/d_DLL.htm ) I used comtypes' GetModule to generate the interface code. I haven't yet experimented further though.

BTW, there is a complete lack of DirectDraw
examples out there, especially using Python. If someone has links to such
I'd appreciate it, especially those for 3D surfaces. (We're slowly trying
to build an accelerated wxPyPlot-like widget that uses OpenGL/DirectDraw
- and I mean slowly...)
