In MFC, the base class used for displaying dialog boxes on the screen.

Dialog boxes are of two types: modal and modeless. A modal dialog box must be closed by the user before the application continues. A modeless dialog box allows the user to display the dialog box and return to another task without canceling or removing the dialog box.

A CDialog object is a combination of a dialog template and a CDialog-derived class. Use the dialog editor to create the dialog template and store it in a resource, then use the Add Class wizard to create a class derived from CDialog.
