2.Launch Visual Studio 2005 and start the Device Emulator Manager from the "Tools" menu. Launch the emulator from the emulator's list.
After the emulator is launched, right click current emulator (in the Device Manager) and select the "Cradle" menu item 
3.Go to emulator itself, launch ActiveSync and select "Connect via DMA..." 
4.Launch Mobile View and go to manage your virtual device.
