// propertysheet.h
//  Declaration of the following classes:
//  CPropertyPage and CPropertySheet

// These classes add support for property sheets to Win32++. A property sheet
// will have one or more property pages. These pages are much like dialogs
// which are presented within a tabbed dialog or within a wizard. The data
// on a property page can be validated before the next page is presented.
// Property sheets have three modes of use: Modal, Modeless, and Wizard.
//
// Refer to the PropertySheet demo program for an example of how propert sheets
// can be used.
