Hi I succeed to finish my code of simple viewer PC screen. Work with WP7

Now I will go to try how control the mouse?
About my app I use socket to connect to the server, no RDP protocol and its word good. I try it on different machines and networks (@IP) and work perfect.

My app is a last year project so any idea about how to control the cursor.
