which WM_ to find out when mouse gets out?

Hello again,

which WM_ message can you use to find out when mouse gets out of client area? I checked out the documentation, and the only ones I find that can possibly relate is WM_CAPTURECHANGED, but that doesnt really work..

is it that I'm missing something, or is the only way is to keep testing every now and then if the mouse is out of the client area?

WM_MOUSELEAVE.

msdn : mouse input.

thanks. looks like my reference file is a bit too old..
