I'm not sure why you cannot get past the first chance exception. If you
don't try to trap it, and don't have exceptions break into the debugger (in
the IDE) then the exception should just be ignored. I certainly wouldn't put
a Try ... Catch around the code, because it is in the InitializeComponent
sub, and that will get overwritten by the designer. Go to Debug |
Exceptions, and check that Common Language Runtime Exceptions are set to
Continue "When the exception is thrown". In these conditions, my Windows
form loads without reporting an exception.
