>Hi,
> I would like to pause my processes when mycertain control be pressed and resume when drag was release. I placed my pause methos in mouse down event and resume method in mouseup. It works fine in certain situation only. When I drag on my control and move to others place out of mycontrol, my resume method won't called. I have tried to place the code in click event either, but not work too. Any suggestion?

One possible solution might be to test in the MouseMove event, so that after processing has been paused, if the mouse cursor is dragged off the control, processing is resumed ( as well as in MouseUp event ).
