MDI Application Ploblem with NT 4.0

Hi all,
I wrote an MDI application in which every MDI Child Window is a dialog box created with the resource editor, with the extended flag MDI Child checked and with a Class that I register at the beginning of the execution.
In every dialog-window procedure I use the DefMDIChildProc function to manage the message I don't care. I create the dialog box with CreateDialog function.
My application works well in Windows 95, but when I tried to run it on NT 4.0 (Workstation) I saw a very strange behaviour: the dialog boxs don't paint correctly and I don't see the list of the windows in the Window Menu.
If I open a MDI test-window with CreateMDIWindow I saw it normally...
I use Borland C++ 5.01A

Win NT is much less tolerant to 'workarounds' than Win95 on things like you did. You should create the MDI child via CreateMDIWindow() and then use the Dialog in the client area of the MDIChild window (just specify the MIDChild as parent of the dialog). You may need to override the MDIChildWindowProc to avoid resizing of the window, but you will get the right MDI feeling as a result.
