yes showwindow function returns a non zero value ie 16 means it runs successfully but the minimized window does not populate on the screen.
yes one more issue, IsIconic returns true for the first window application and false for the minimized one that does not populate on the screen.
yes when minimized, it is shown in the taskbar.
yes it was visible before it was minimized.
no, the main window(minimized) does not have any child window.

Thanks a lot , its working fine.
