// about2.h : Declares the class interfaces for the About2 application.
//            This application demonstrates typical modal dialog use,
//            painting special graphics on a modal dialog, and when
//            compared to the original C code, shows equivalent
//            functionality between C code and C++ Foundation code.
//
// This is a part of the Microsoft Foundation Classes C++ library.

//
// This source code is only intended as a supplement to the
// Microsoft Foundation Classes Reference and Microsoft
// QuickHelp documentation provided with the library.
// See these sources for detailed information regarding the

// Based on the About2 application by Charles Petzold.
// The original application appeared in
// "Programming Windows", Second Edition (pp. 417-423),
