Debugging Help

[Dodgeram01]

I have a programed, named Camplist...which I have been working on for a while. Recently it's been on hold. It will run fine on my compouter, but on some other computers it will give an error. It gave my friend an error number of 940 and of 646. However, when I searched those numbers in the error lookup deal, it didn't yield any results. I do know those are the numbers though. It's exhibited the same sort of behavior ago. I don't understand why it will error on their computers, and not on mine? They have the .NET Framework installed, and also Service Pack 1 for it. Does anyone of any suggestions, or would someone perhaps be willing to look over the code for me? I would appreciate it. Thanks. Email me if you're interested: ghassel1@twcny.rr.com
