Well, three options:

1) Don't do the connection within the form construction. Do it before
you construct the form, but while the splash screen is up.

2) Handle the exception so that customers don't see an unhandled
exception. Don't forget that until your constructor has returned,
Application.Run hasn't been called, which is why Application.Exit isn't
working. A simple try/catch in your Main method should work here, I
believe.

3) Use Environment.Exit instead.
