How do MDI acting like SDI?
As i only want 1 instance at a time and only 1 active form is showing, and is it possible that the child window set as the child form as like VC++...
if possible, please provide sample.

There is no direct equivalent of MFC's doc/view architecture. Your application is either MDI or SDI. So if you didn't specify MDI explicitly, then you have an SDI application already.
