How to take a screenshot on a Windows CE 5.0 device
Search for "ActiveSync Remote Display" -- you may find it bundled with some MS Mobile dev. tools. It lets you display your CE device's screen on your PC which then makes it very easy to grab screen shots using more traditional methods (like Vista Snipper or alt-prtscr).
Try "Screenshot Mobile" (freeware), works on Windows CE and Windows Mobile, more here: http://venea.net/link/screenshot_ce
