Hi guys,
Hope you guys can give me assistance with this little 'DirectInput' problem I am having.
Basically in my code when I try to Acquire() my keyboard device it is returning a 'FAILED' result and I am not sure why.

baseWindow->registerWindowClass();
baseWindow->createWindow();

direct3DInput = new Direct3DInput;
direct3DInput->initDirectInput( hInstance, baseWindow->getHandle() );
setupGame();
baseWindow->show();
MSG msg;
ZeroMemory( &msg, sizeof( MSG ));
while( msg.message != WM_QUIT )

{
if( FAILED( DirectInput8Create( hInstance, DIRECTINPUT_VERSION, IID_IDirectInput8, ( void ** ) &inputSystem, NULL )))
{
MessageBox( 0, "Direct3DInput::initDirectInput() 1", 0, MB_OK );
}
if( FAILED( inputSystem->CreateDevice( GUID_SysKeyboard, &keyboard, NULL )))
{
MessageBox( 0, "Direct3DInput::initDirectInput() 2", 0, MB_OK );
}
if( FAILED( keyboard->SetDataFormat( &c_dfDIKeyboard )))
{
MessageBox( 0, "Direct3DInput::initDirectInput() 3", 0, MB_OK );
}
if( FAILED( keyboard->SetCooperativeLevel( hWnd, DISCL_FOREGROUND | DISCL_NONEXCLUSIVE )))
{
MessageBox( 0, "Direct3DInput::initDirectInput() 4", 0, MB_OK );
}
if( FAILED( keyboard->Acquire() ))
{
// When it gets to this part... it fails and hence goes into 'if' body.
MessageBox( 0, "Direct3DInput::initDirectInput() 5", 0, MB_OK );
}
ZeroMemory(keys, KEY_SIZE * sizeof( char ));
}
... //other function omitted.
I even try catching the error values DIERR_INVALIDPARAM, DIERR_NOTINITIALIZED and DIERR_OTHERAPPHASPRIO but these are not the errors that is being returned.
Let me show you what I mean...
if( FAILED( keyboard->Acquire() ))
{
if( S_FALSE == DIERR_NOTINITIALIZED )
{
MessageBox( 0, "Direct3DInput::initDirectInput() 5", 0, MB_OK );
}
}
But when I do the above... it doesn't go into the 2nd if at all, even if I change the error value to one of the other ones, the 2nd 'if' doesn't catch it.
So I don't really know why I can't acquire my keyboard.
Any help is really appreciated :-D
P.S. Some will tell me not to use DirectInput anymore... and I've read some post about it. In the near future I will properly research and get a more in depth understanding of it all... but for now and my this case I've decided to stick with it.
