That's what I am doing.
I am displaying a small form and I need to erase a section of the old
form before displaying mine. I do this by:
FrmInitForm()
FrmGetBounds() (I think that is the name...to get the size of my new form)
WinEraseRectangle() (to clear this area)
FrmSetActiveForm() (set my new form to be active)
FrmSetEventHandler()
FrmDrawForm()
