Dialogs

Dialogs are windows displayed by a program for the purpose of exchanging specific information with the user. There are two kinds of dialogs:

• Modal dialogs block all other interaction with the program until the dialog is closed.
• Non-modal dialogs allow the user to interact with the program in other ways while the dialog is open.

We will examine three classes provided by Microsoft® .NET 6, each of which implements a modal dialog. .NET provides various other classes, such as FolderBrowserDialog, FontDialog, and ColorDialog, that also implement specific kinds of dialogs. We conclude by discussing how custom dialogs may be built using Visual Studio®.
