At what stage does this exception occour?

Have you hear of a break point? if you hit F9 on a line of code the system will stop when it runs to that line, you can then step through your code using F10 and F11 line by line to see where the error occours.

Your problem is that you seem to be trying to connect to an .sdf file on your desktop from the PDA... put the sdf on the emulator itself then connect to it...

i.e. "My Documents\Busin ess\myDatabase. sdf"

If you want to share a folder to get the file on there go to the options for the emulator "File > Configure" I think.. then add a shared folder from your PC, this will show up as a memory card on the emulator allowing you to move/access files from the PC on the emulator
