Hi, I''m trying to initialize Direct3D in C++ as shown in the tutorials. I use both VS.NET and VC6 but get the same error (unresolved external symbol _Direct3DCreate9@4 or something like that) in the line: if(NULL == (pD3D = Direct3DCreate8(D3D_SDK_VERSION))) return E_FAIL; (Exactly like in the tutorial). Is anything else required to be included except d3d9.h? Exactly the same thing occurs if I try to use DirectX 8 instead of 9. It seems very strange to me because samples who seem to have this same code, run normally. Any ideas? Thanks to anyone who might answer.

are you linking in the lib file? If not try adding this line to any source file

#pragma comment ( lib, "d3d9.lib" )

That line just links in the d3d9 library, which you need to link in order to compile d3d9 stuffage.

you need to include the d3d9.lib files and dxguid.lib as well. And for gods sake include them the way they were ment to be included and not in some #pragma. That makes for some very ugly code.

Sorry but I''m not any good at C++. Could you please explain in more detail how to link these files? The #pragma directive doesn''t fix the error. How can I include the two files you mention? If I add #include "d3d9.lib" it says it can''t find the file...

You need to link the Direct3D 8 libs, not the Direct3D 9 that those above have shown.

It depends on what compiler you are using. If you are using VC7, right-click your project, go into linker settings, and add the appropriate libraries.
