Closing Main window with out Closing the child window

["Prabhakar Muthuswamy" <Prabhakar Muthuswamy raritan com>]

All

     I have a main window (which is a login screen) after I am
authenticated this main window should go away and other window should
pop up. As of now I am able to pop the second window but the main window
is hiding behind the second window. Is there an API which would allow me
to close the main window with out closing the entire application?

 

Thanks
