In my start up code, I get 2 errors: C:\Program Files\Microsoft Visual Studio\MyProjects\editor1\killthacraka.cpp(174) : error C2065: ''DirectInputCreate'' : undeclared identifier C:\Program Files\Microsoft Visual Studio\MyProjects\editor1\killthacraka.cpp(177) : error C2664: ''CreateDeviceEx'' : cannot convert parameter 3 from ''struct IDirectInputDeviceA ** '' to ''void ** '' heres what it''s saying is wrong: if(FAILED(DirectInputCreate(main_window_handle,DIRECTINPUT_VERSION,IID_IDirectInput7,&lpdi,NULL))) return(0); if(FAILED(lpdi->CreateDeviceEx(GUID_SysKeyboard,IID_IDirectInputDevice7,&lpdikeyboard,NULL))) return(0); Me and my friend can''t figure it out. All the correct libs are linked, I included the headers. I''m using DX7 for this with DirectDraw.

Shouldn''t ''DirectInputCreate'' be ''DirectInputCreate7'' or osmething similar? Or you''re not including ''dinput.lib''. (or whatever its called)

  
if(FAILED(lpdi->CreateDeviceEx(GUID_SysKeyboard,IID_IDirectInputDevice7,&lpdikeyboard,NULL)))
return(0);

should be:
if(FAILED(lpdi->CreateDeviceEx(GUID_SysKeyboard,IID_IDirectInputDevice7,(void**)&lpdikeyboard,NULL)))
return(0);

I think the function should be CreateDirectInputEx() if you are using DirectInput7

I will not make a list of links... I will not make a list of links... I will not make a list of links...

I tried that too. Thats what I had originally, but I forgot to change it back. I got the same results with it too.

Try defining DIRECTINPUT_VERSION to 0x0700. By default, dinput.h includes only DX8 creation function.

For your second error, you need what Evil Bill said.
