//  Class:      CHlprPropPage
//
//  Purpose:    virtual base class for wrapping Windows' dialog functionality
//
//  Interface:  ShowDialog -- analagous to the Windows DialogBox function
//              DialogProc -- pure virtual DialogProc for the dialog box
//              ~CHlprPropPage   -- destructor
//
//  History:    4-12-94   stevebl   Created
//              7-02-1997   stevebl   added CreateDlg
//
//  Notes:      This class allows a dialog box to be cleanly wrapped in
//              a c++ class.  Specifically, it provides a way for a c++ class
//              to use one of its methods as a DialogProc, giving it a "this"
//              pointer and allowing it to have direct access to all of its
//              private members.
