and here is the exception I get:
System.InvalidOperationException: Forms that are already displayed modally cannot be displayed as a modal dialog. Close the form before calling showDialog.
I don't know why I get this exception. I must have done somethig wrong but I can't figure it out!
If you could just look over the code I provided and give me hint on how to fix this, I would be very grateful.
Please forgive me for posting such a large piece of code, but I thought that giving you the whole code, would help you to get the hole idea.
Any help, hint, idea very much appreciated.
Please answer as quickly as possible because without this I cannot continue the project I'm working on!
Cheers to all of you,
Adisor
