// dialog.h
// Declaration of the CDialog class
// CDialog adds support for dialogs to Win32++. Dialogs are specialised
// windows which are a parent window for common controls. Common controls
// are special window types such as buttons, edit controls, tree views,
// list views, static text etc.
// The layout of a dialog is typically defined in a resource script file
// (often Resource.rc). While this script file can be constructed manually,
// it is often created using a resource editor. If your compiler doesn't
// include a resource editor, you might find ResEdit useful. It is a free
// resource editor available for download at:
// http://www.resedit.net/
// CDialog supports modal and modeless dialogs. It also supports the creation
// of dialogs defined in a resource script file, as well as those defined in
// a dialog template.
// Use the Dialog generic program as the starting point for your own dialog
// applications.
// The DlgSubclass sample demonstrates how to use subclassing to customise
// the behaviour of common controls in a dialog.
