Hello,
When you move your mouse in Windows Media Play full screen mode, you can see the control bar, then it disappear after awhile. I am trying to do the same. Is there a good example for this?
 
I am thinking about a Mouse Stop Capture approach, anyone using this way?
 
Thank you.

You can use a timer, check if the mouse pos changed since last call. Check DispatcherTimer, this is a low overhead timer, very suited for this kind of job.

Thank you. It works really well. And I am able to use it to make my other part of the code cleaner.
