I'm trying to port over a simple DirectInputCreate example in MSVC++ .NET and its not linking. I get error LNK2019: unresolved external symbol _DirectInputCreate referenced. I have DirectX 9 and I am including dxguid.lib dinput.lib dinput8.lib in my project. So there might be some kind of compatablility probem with DirectInputCreate. Anyone have an idea?

Try DirectInput8Create(). Note the '8' in the name.

ahhh... well anyone know what I might be missing?

LPDIRECTINPUT                   g_lpDI = NULL;  // Create the DirectInput COM object. //if(DirectInputCreate(hinst, DIRECTINPUT_VERSION, &g_lpDI, NULL) != DI_OK)   if(DirectInput8Create(hinst, 0x0300, &g_lpDI, NULL) != DI_OK){...}I need a 5th item for DirectInput8CreateHRESULT WINAPI DirectInput8Create(              HINSTANCE hinst,  // got this..    DWORD dwVersion,  // got this..    REFIID riidltf,       // I'm lost here...    LPVOID *ppvOut,       // I'm lost here...    LPUNKNOWN punkOuter   // And I'm lost here...);

pUnkOuter is COM weirdness, just set it to NULL for now, you don't really need to know what it does anyway, I don't. [smile]

From DirectX SDK Docs:

Quote:

riidltf
Unique identifier of the desired interface. This value is IID_IDirectInput8A or IID_IDirectInput8W. Passing the IID_IDirectInput8 define selects the ANSI or Unicode version of the interface, depending on whether UNICODE is defined during compilation.
ppvOut
Address of a pointer to a variable to receive the interface pointer if the call succeeds.

DirectInput is a relatively easy API to learn, all that you would need to know is included in the DirectX SDK documentation. There are five or six tutorials there that just about cover the entire API, the rest is documented quite well in close to the same place.

Cool thanks, I'm going to look at that tonight
