Thanx!
But now, when I do this the external window doesn't really behave like a child window should do. It does minimize when I minimize my form.. only a fraction later. And when I maximize my form again, the external window maximizes first and then my form is placed on top. Also: the external window doesn't stay in the borders of my form.
What can I do to make it a perfect Client window?
Thanx in advance!!
