I am pretty new to DirectX and have just downloaded the 8.0 SDK. I have installed it, and every time i want to compile a source-code, the damn compiler gives me this message "Error: Unresolved external ''DirectDrawCreate'' referenced from module programm.cpp" I tried various source-codes, but the error remains the saim. What can I do? I´m using the Borland C++ Compiler (version 5,01).

Post the source and I may be able to help ya out.

This is just one source-code i tried. It´s from the SDK, but the same error appears as in all my tests.

// tutorial, we are using vertices that are transformed (meaning they
// are already in 2D window coordinates) and lit (meaning we are not
// using Direct3D lighting, but are supplying our own colors).

I''ll have to agree with the others. It''s probably best to use MSVC. There may be something wrong with the way you set things up in BC. Is it a compiler or linker error. (sounds like a linker error.) You may have forgot to include D3D.LIB in with the linker.

So with that code, you get-

"Error: Unresolved external ''DirectDrawCreate'' referenced from module programm.cpp"

That is strange for a program that isn''t using DirectDrawCreate() or DirectDraw. If you''re linking to ddraw.lib then you shouldn''t be. You should be linking to d3d8.lib.

Thanx!
This time it worked!
