recording screens on PocketPc's

Question

Hello, Can anybody explain me here how i can make periodically every five seconds screen shots on the Pocket Pc? - Means that automatically every five seconds should be made a screen shot of the display of the PocketPc and should be saved. Respectively is it possible that a screen shot of the display of the PocketPc is made when any event on the PocketPc occurs? Thanks in Advance. Regards. Patrick
