demonstratectlview.cpp

MFC下编程 展示了对话框如何与视图对象交换数据

// DemonstrateCTLView.cpp : implementation of the CDemonstrateCTLView class
//

#include "stdafx.h"
#include "DemonstrateCTL.h"
/*---------------------------Sammy2006.11.1------------------------------
下面的两个Include语句顺序不能颠倒，因为在类CDemonstrateCTLView的声明中
有CDemonstrateCTLDoc* GetDocument()语句，说明在类CDemonstrateCTLView的
声明中用到了CDemonstrateCTLDoc类，所以必须先声明CDemonstrateCTLDoc类，再声明
CDemonstrateCTLView类，否则编译器无法识别CDemonstrateCTLDoc

//下面的Include由Sammy加
