Debugging a problem adding a Usercontrol to a form

[Just Me]

I have a large Usercontrol that I just converted from VB6 (so I'm not
surprised there are bugs in it.)

When I try to add an instance to a form I get an exception occurred trying
to create and instance, "Specified cast not valid"
If it happened at runtime I would breakpoint and single step to find the
statement causing the problem.

What can I do at design time to localize the bug?

Thanks

Hi Just me,

Do you have option Strict On in all your forms?
