Associating a Dialog with a Notebook Page

To understand the notebook implemented as a dialog, a Properties Notebook is used. The various objects whose properties can be changed or updated are displayed as major tabs. Included are sections that represent a folder, printer, and display (major tabs). The printer object is currently selected. Within the printer object, the user can choose to "View" or "Update" (minor tabs) the printer settings. The topmost page is a printer dialog from which the user can update the printer name, type, and device information.

The following sample code shows how the printer dialog is created and associated with a notebook page. The example ends by showing the dialog procedure for the associated dialog.
