CIS162AD 2




Each form is in a separate window that acts independently from the other forms in the application.
This what we have created so far.
Even when we display another form (ShowDialog), the 2 nd form is displayed in its own window, for example the About form. It is independent of the startup or main form.

Multiple forms are displayed within the same window.
Parent form (main window) "contains" other forms.
Many Child forms (document windows) can be
"contained within" Parent window.
Parent and Child may share menus, toolbars, etc.
Should add a Window menu option that allows users:
– To switch between opened documents.
– Display documents as Tile Vertically, Tile Horizontally or
Cascade.
