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 fr a mework. 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 fr a mework of several types of roles and mutual relations, MFC fr a me 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.
