Just like the subject says my Acquire() function always fails and I have no idea why it's doing that. What can cause this function to fail? Here's my code. The Acquire is at the very bottom.
  
// Initialize DirectInput

bool CGame::InitializeDI(HINSTANCE hInst, HWND hWnd)
{
	//	Set up the Direct Input Stuff

	HRESULT hr;

	hr = (DirectInput8Create(hInst, DIRECTINPUT_VERSION, IID_IDirectInput8, (void**)&m_pDI, NULL));
	
	if (FAILED(hr))
	{
		WriteToLog("ERROR initializing DirectInput8.");
		return FALSE;
	}

	if (FAILED(m_pDI->CreateDevice(GUID_SysKeyboard, &m_pKeyboard, NULL)))
	{
		WriteToLog("ERROR Creating DirectInput Device.");
		return FALSE;
	}

	if (FAILED(m_pKeyboard->SetDataFormat(&c_dfDIKeyboard)))
	{
		m_pKeyboard->Release();
		WriteToLog("ERROR Setting DataFormat for DirectInput.");
		return FALSE;
	}

	if (FAILED(m_pKeyboard->SetCooperativeLevel(hWnd, DISCL_FOREGROUND | DISCL_NONEXCLUSIVE)))
	{
		m_pKeyboard->Release();
		WriteToLog("ERROR Setting Cooperative Level for DirectInput.");
		return FALSE;
	}

	if (FAILED(m_pKeyboard->Acquire()))
	{
		m_pKeyboard->Release();
		WriteToLog("ERROR Acquire for DirectInput.");
		return FALSE;
	}

	return true;
}
  
Anybody have any ideas? Quiggy. [edited by - Quiggy on January 30, 2003 7:56:23 PM]

Shots in the dark:

1) Is the window (HWND) actually created and displayed by the time you call Aquire?

2) Have you tried creating a buffersize before aquiring?



DIPROPDWORD propdword;
memset(&propdword, 0, sizeof(propdword));

propdword.diph.dwSize = sizeof(propdword);
propdword.diph.dwHeaderSize = sizeof(DIPROPHEADER);
propdword.diph.dwObj = 0;
propdword.diph.dwHow = DIPH_DEVICE;
propdword.dwData = 16;

m_pKeyboard->SetProperty(DIPROP_BUFFERSIZE, &propdword.diph);
