i got the following error " Unhandled exception at 0x00421dc4 in test.exe: 0xC0000005: Access violation reading location 0x00000004. " with the following code.



bool CInput::Update(void)
{
	Keyboard->GetDeviceState(sizeof(UCHAR[256]),(LPVOID)&KeyBuffer);

	return true;
}

My guess is that the value of this or Keyboard is 0. What does the debugger tell you?
