// 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).
