Remarks

A top-level application window is the main window of an application; it has no owner windows. As with other application windows, a top application window can have icons, captions, resizeable borders, menus, and system menus. An application can have more than one top application window.

Examples

This example creates a top application window with the caption "TopAppWindow":
