MDI isn't dead, it's merely abused a lot. We'll say the same thing about that Ribbon on a few years :) BillWoodruff wrote: I think you can get better responses to this scenario if you describe what the function of your proposed use of "Child Forms" are, in relation to their "Parent" Form. Good point; when an apparant beginner talks about child-forms, I usually assume (I know, we should check, not assume) that they need to display a dialog, and that they forgot to specify the owner of the form (often confused with the parent). +5 for giving a very elaborate answer that does not only benefit the TS.
