I have what is probably a simple question, I have an application that I would like to use as part of a larger application, kind of like a modular piece. I realize that I'll have to re-tool the current application some, but what I really want is to build a larger form that will allow me to "nest" my existing form inside of it? What type of control is that? In Powerbuilder this is built in, but I don't have that option here. I'd like this larger application to have a couple of menu items, and a toolbar to open the different "nested" forms inside of it.
