SetParent won't give you the MDI Child form functionality.

That's one of the side effects of SetParent.

MDI Parent forms are very stubborn. They only treat MDI Child forms that are
part of the same project as children. There's nothing that can be done about
that except.....

The usual way people do this kind of thing is add a real MDI Child form to
the project and then load a custom OCX that represents a form onto that real
child. I'm not sure about .Net but in VB, this method works well because
Usercontrols are really just a specialized form. All code you can place in a
form can work in a VB6 OCX (more or less... there's no Form_Load or similar
in an OCX but it has equivalent events)

So, if you can convert that DLL into a Usercontrol that VB can load at
runtime, and load that onto a real child form, you'll be set.
