My error: LNK2001: unresolved external symbol _IID_IDirectInput8A My code (linebreaks added here only): if (FAILED(DirectInput8Create(GetModuleHandle(NULL), DIRECTINPUT_VERSION, IID_IDirectInput8, (VOID**)&diobject, NULL))) return 0x02; My includes: #include <windows.h> #include <d3dx9.h> #define DIRECTINPUT_VERSION 0x0800 #include <dinput.h> My links: d3dx9.lib d3d9.lib dinput8.lib I'm just working with this for the first time, and I did everything almost exactly like the reference and samples, as far as I can tell.

That worked. Thank you.
