Do they have some relationship?

[Guoguor]

When I use CreateWindow function to create a window, I must assign a HINSTANCE to the function ,just as follows: HWND ghApp; HINSTANCE ghInst; ghApp = CreateWindow(CLASSNAME, APPLICATIONNAME, WS_OVERLAPPED | WS_CAPTION, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, 0, 0, ghInst, 0); Now,can you tell me the relationship of ghApp and ghInst? and the difference of the two?

As per the MSDN docs this parameter has been ignored since WinNT. ...cmk Save the whales - collect the whole set
