Does anybody know how I can 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
I've used My Mobiler on 6.0 and 6.1. According to the site it supports 5.0 too, but I can't vouch for that.
