// Declaration of the following classes:
// CWinApp, CWnd, CWinException, CCriticalSection,
// CPoint, CRect, and CSize
//
// This file contains the declarations for the core set of classes required to
// create simple windows using Win32++.
//
// 1) CCriticalSection: This class is used internally to manage thread access
// to shared resources. You can also use this class to lock and
// release your own critical sections.
//
// 2) CWinException: This class is used internally by Win32++ to handle
// exceptions. You can also use it to throw and catch exceptions.
//
// 3) WinApp: This class is used start Win32++ and run the message loop. You
// should inherit from this class to start Win32++ in your own
// application.
//
// 4) CWnd: This class is used to represent a window. It provides a means
// of creating the window, and handling its messages. Inherit
// from this class to define and control windows.
//
//
// Note: This header file (or another Win32++ header file which includes it)
// should be included before all other header files. It sets some
// important macros which need to be set before including Windows.h
// Including this file first also allows it to disable some pointless
// warning messages (see below).
