DInput EnumDevices callback-function error

Hey Guys, because I have solved a problem with your help earlier, I post my "new" problem to this great forum, hoping sb. had the same too. I aquired a Keyboard with DInput without problems. Now I want to enumerate and aquire a joystick. But I always get an error message calling callback-functions from inside a class-function. My code is (only the important): //-------------------------------------------------------------- BOOL CALLBACK CMyD3DApplication::DIEnumDevicesCallback(const DIDEVICEINSTANCE* pdidInstance, VOID* pContext) { HRESULT hr; // Obtain an interface to the enumerated joystick. hr = g_pDI->CreateDevice(pdidInstance->guidInstance, &g_pJoystick, NULL); if(FAILED(hr)) return DIENUM_CONTINUE; return DIENUM_STOP; } HRESULT CMyD3DApplication::OnCreateDevice( HWND hWnd ) { HRESULT hr; [...] if( FAILED( hr = DirectInput8Create( GetModuleHandle(NULL), DIRECTINPUT_VERSION, IID_IDirectInput8, (VOID**)&g_pDI, NULL ) ) ) return hr; if( FAILED( hr = g_pDI->EnumDevices( DI8DEVCLASS_GAMECTRL, DIEnumDevicesCallback, NULL, DIEDFL_ATTACHEDONLY ) ) ) return hr; [...] } //-------------------------------------------------------------- Now I get the following error message from my VC++ 6.0 compiler: cannot convert parameter 2 from ''int (const struct DIDEVICEINSTANCEA *,void *)'' to ''int (__stdcall *)(const struct DIDEVICEINSTANCEA *,void *)'' Hope anyone knows an answer, because I have to use the enumeration call inside the class function. I don''t know much about callback functions at all (didn''t need them up to now) and I also don''t know what the compiler means with __stdcall-pointer ??!! Please Help! Thanks you a lot again, Greetings, Andy
