[RESOLVED] Displaying MDIChild form within an MDIChild form

[Keith Lockhart]

Hello,

I have an MDI application; the parent form calls a "base" MDIChild form, which, for sake of argument, has graphical imagery that looks like the picture of a television set.

Within the "screen" area of my television, I want to show various "sub-MDIChild" forms, based on controls clicked in the base MDIChild. Is there a way to display forms within a frame on the base MDIChild, and have all the "sub-MDIChildren" act properly.

Thanks for your help.

all depends on what you mean by 'act properly'

I mean it acts like an MDIChild of the MDIChild...i.e., stays witihin the form, resizes properly when minimized and restored, etc.

what you can do is place a normal form within a another window e.g. a MDIChild or PictureBox etc. using the SetParent API.

Unfortunately it won't resize when its new parent is resized - even if you change the windowstyle constants then the messages still don't get through for some reason. I've never seen a non-fudge solution for it.

Okay, thanks.

I wouldn't mark this thread resolved, someone may have a solution, and I for one would be very keen to see it

Actually, I resolved it by using Joacim Andersson's solution at:

oh i see, your just going to position the other MDIChilds relative to the base one, giving the illusion of having them within the window rather actually putting them there.
