Problems with 3Dfx OpenGL window creation.

I’ve created an OpenGL window using opengl32.dll from Homeworld: Cataclysm demo.
Now it supports 3Dfx cards but with one problem.
When I use this dll in any of NeHe’s ( OpenGL tutorials it works fine (It was written in VC++). But when I try the same code (copy/paste) in my application (in C++ Builder 4) it doesn’t work ! Is says error when I try to activate GL rendering context. If you want I’ll send you my source code. Please help me !
Thanx !

Try getting an OpenGL component like the one at or the OpenGL Challenge has an OpenGL skeleton app for Builder.
