MFC入门教程VS2013
点击C++里的MFC再点击MFCApplication，到下面改名字和路径，然后OK
然后点击Next，
选择single document，MFCstandard，简体中文，然后Finish
这时候可以先直接运行，看看工程的样子，操作如下
编译完成，
稍后有个空白菜单框弹出；
我们先创建资源视图，点击解决方案，再资源文件里找到以rc开头的文件双击，如图
双击后就会有四个视图
先点击Class view，再点击CMFCApplication1View（这里名字不一样，但都是以View结尾的），
鼠标右键****View那个类，如图
点击Class Wizard
对清一下信息，从Message里找到WM_LBUTTONDOWN和WM_LBUTTONUP和WM_MOUSEMOVE分别双击他们(他们按照字母顺序排列的)
关了这个窗口，点击是
进入以下界面
点击右边的****view.h,双击它
双击后找到protected，在里面添加***view类的全局变量CPoint m_point;
BOOL m_signal;
CPoint m_point2;
添加后
再点击***view.cpp
找到
选中这三个函数，删掉这段代码
然后复制粘贴上这段代码

点击DEBUG
就会出现画曲线的程序，这是因为我画曲线的代码没注释掉(/* */和//)
你们可以把画曲线的代码注释掉，把画直线的注释去掉，再运行，就是画直线的了其他都可以运行，只有涂鸦的不行，因为涂鸦还要操作：
1.去掉涂鸦代码的注释，把其他代码（三个函数）注释，
2.点击资源视图，找到以.rc结尾的文件，按鼠标右键，选择添加资源，如图
双击Bitmap
点击画笔如图，在格子里画要涂鸦的内容
我写了个李，然后再关闭这个窗口，点击如图，然后是保存
然后运行，就是涂鸦的程序了
四个程序都能运行了
