12.2.3..A Modal Dialog Box in an Application...........................................

Some applications require various dialog boxes to complete their functionality. When in

case, you may need to call one dialog box from another and display it as modal. Here is

an example:

The Paragraph dialog box of

WordPad is a modal dialog box:

when it is displaying, the user

cannot use any other part of

WordPad unless he or she

closes this object first

Since a dialog box is created using a class, the first thing you must do is to include the

header file of the CDialog object whose box you want to call.

To call one dialog box from another window, select the event (or message) from where

you would make the call. Declare a variable of the other class and use the

CDialog::DoModal() method to display the other object as a modal dialog box.

Calling a dialog box from the menu of a frame-based application is done the same way as

calling it from a dialog box
