Problem with d3d rotation.

Ok when I compile the sdk tutorial source code for matrices. It worked using the function timeGetTime(). It used this in rotating the around the y axis. When I used it it gave me an error. Also I would like someone to look over my code and see if it is correct.

	FLOAT x,y,z;
	DWORD color;
};

Your help is greatly appreciated. I'm a noob to directx so thats why i'm posting so much, but i'm learning a lot. Thanks again, Cory EDIT: here is the error message: linking... main.obj : error LNK2001: unresolved external symbol __imp__timeGetTime@0 Debug/usingmats.exe : fatal error LNK1120: 1 unresolved externals Error executing link.exe.
