I'm having trouble compiling a program using DirectDraw. Actually, it compiles fine (my program) but I get a linker error. I've set both the DirectX sdk include and lib paths and I also manually included the "ddraw.lib" library. When I try to build the application I get a LNK2001 error: "unresolved external symbol _IID_IDirectDraw4". Does anyone know how to fix this?
