I asked this once before, but I'm still unsure.

In VFP, I have a Window Manager class. You call

_Screen.oApp.oWindows.LaunchForm("SomeFormClass", p1, p2, ...)

and internanlly, the class does a CREATEOBJECT("SomeFormClass") and stores the object reference to a
collection.

Since the Windows class is attached to the Application class, which is attached to
_Screen, I can always get a reference to a form using the object hierarcy.

What I'm trying to acheive is form control. I want to be able to get data from one
form or another, or close a form, or reposition forms (via Window Menu, Arrage bar)
and other similar functions.

Basically, the window manager class controls, or keeps track of, all open windows in
the app.

How would I do something like this in C#?
