OnMouseOver in Visual C++

Question:
I have found many resources discussing the OnMouseOver event in JavaScript. I would like to know if this event is available in VC++ in any capacity, whether through an added event handler or if there is an IE4-like control that adds this functionality.

Answer:
If you are using MFC and have a CWnd object that has duly subclassed a window, you can have Class Wizards automatically add an OnMouseMove handler for you. This function corresponds to the Windows' WM_MOUSEMOVE message and notifies you any time the user moves the mouse over your window.
