11.1 What is a Dialog Box?

A dialog box is defined as a rectangular window whose major role is to hold other Windows
controls. For this cause, a dialog box is pointed to as a container. It is the chief interface of user
communication with the computer. By itself, a dialog box means nothing. The controls it holds
achieve the role of dialog among the user and the machine.
A dialog box has the following traits:
 It is equipped with the system Close button . As the only system button, this button
permits the user to release the dialog and overlook whatever the user would have done on
the dialog box.

 It cannot be minimized, maximized, or restored. A dialog box does not have any other
system button but Close.
