How to ignore WM_MOUSEMOVE?

[emccarty]

What I would like to do is to have the system ignore WM_MOUSEMOVE events. So on WM_LBUTTONDOWN start ignoring and then on WM_LBUTTONUP start listening again. BlockInput() would mean I never get the button up message. Is this possible?

Thank you!

What do you want to do exactly? Stop the mouse until the user clicks again?

It sounds like what you want is a typical SetCapture/ReleaseCapture cycle. On button presses, for example, the button window executes a SetCapture, all subsequent moves are then "ignored" as it were - no other windows get move messages, and the button still lets the cursor move, but doesn't let go of the message traffic - though you could force the issue in a move response by forcing the location of the mouse no matter what - still holding capture.

ReleaseCapture is called only on the mouse up message.
