How to detect when the mouse is moving outside the window?

Question

I'd like to detect the mouse move event when it's moving outside the window by using MFC. I have used OnNcMouseMove() but it only detects the mouse move event when it's moving to the non-client area, not outside the window. So how can I do to detect while the mouse is moving outside the window?

Answer 1

All I did was set up a 100ms timer that calls GetCursorPos() . You can tweak that timer value to make it higher resolution if needed, but for my specific UI need, 100ms was good enough - it dumped (x,y) coordinates to a status bar.
