讲述MFC AppWizard的原理与MFC程序框架的剖析。AppWizard是一个源代码生成工具，是计算机辅助程序设计工具，WinMain在MFC程序中是如何从源程序中被隐藏的，theApp全局变量是如何被分配的，MFC框架中的几个类的作用与相互关系，MFC框架窗口是如何产生和销毁的，对窗口类的PreCreateWidow和OnCreate两个函数的着重分析,Windows窗口与C++中的CWnd类的关系。-MFC AppWizard on Principle and analysis of MFC Framework. AppWizard is a source code generation tool that is computer-aided process design tools, WinMain in MFC process is how to from the source was hidden, theApp global variable is how the distribution, MFC framework of several types of roles and mutual relations, MFC frame window is how the generation and destruction of the window class PreCreateWidow and OnCreate function of the focus on analysis of the two, Windows window with the C++ the CWnd class relations.
