I have written a program that works well for my clients, but it depends upon a drive mapping (I:) to be there. Of course, I know my error trapping is not as good as it should be since this is the first time I have written a VB program that is actually being used by someone.

So here are the questions:

How do I know if the drive mapping has been lost?

How do I reestablish the drive mapping if I know the UNC path name?

Is there a good tutorial on how to deal with network connections and what errors I should trap for?

Thanks,
