Modal and modeless forms

Question

I have the application in VB.NET where I have a main form (A) which opens another form (B) in modeless state. Then from the form A I want to open another form (C) as modal form.

Is there anyway to do anything on form B whilst the form C is still open?

Welcome to S.O. What have you tried? Could you show us your code? — Daniele Armanasco, Jun 22 '13 at 09:04
You are asking for a very dangerous feature. Read [this answer](http://stackoverflow.com/questions/5181777/use-of-application-doevents/5183623#5183623) to understand why ShowDialog exists. You otherwise get what you ask for by simply using Show() and disabling A by setting its Enabled property to false. — Hans Passant, Jun 22 '13 at 13:10

Wouldn't this be confusing for the user? B apparently needs A to be available but when you open C you break that functionality of B.

Nonetheless, you can probably use EnableWindow() to disable A instead of making C modal.

EnableWindow sounds reasonable. I'll try that. – Grzegorz Gazda Jun 22 '13 at 10:30

You also could switch to an MDI interface.
