i have 2 windows with WS_OVERLAPPEDWINDOW style. can i put 1 inside another one like MDI?

I've used this tutorial back when I was learning WinAPI to implement a MDI:

i can change the extended style for WS_EX_MDICHILD. but i can see some 'bugs', maybe i will do a MDICHILD class for resolve several problems.
and the form will be only for standard forms and dialogs(like font dialog and others).
thanks for all
