I’ve tested to use the Register_Combiners, but now I have an unresolved external. What lib do J need? Please help.

You have to load extension functions yourself when you start your program. Declare a functionpointer and use wglGetProcAddress() to get the address to the function.

There’s source code in the NVIDIA OpenGL SDK that will declare and initialize entry points for all extensions we support.

Please check there, and contact me if you have difficulty.
