Update Description:

NOTE:

i used OpenNetCF API for the vibration. It calls on the Led notification of your device to cause the vibration. But not all devices have the same Led index to vibrate. So you have to click on the "Vibrate" menu item and see if your device vibrates. If not, increase the number shown by the textbox by increments of "1" then test the vibration again.
