VC版绘图，直接在对话框中绘制曲线图，可以在二维与上位之间切换(VC version of the drawing, directly draw graphs in the dialog box, you can switch between two-dimensional and the host)

实现养老院信息管理系统中老人信息管理功能(Information management system to achieve the elderly in nursing homes information management capabilities)

CTreeItem类封装 目录树功能，可实现对目录树的各项需求！(CTreeItem Class from it we can feet comfile)

（1）定义一个抽象基类Shape,同它派生出5个类：圆、正方形、矩形、梯形、三角形。 （2）利用虚函数计算几种图形面积。 （3）演示构造函数、复制构造函数、析构函数的作用和调用顺序 （4）用类模板具体实现。 （5）利用MFC类库在图形用户界面上绘制及修改这些图形，采用对话框输入输出图形的基本属性，或者利用运算符重载输入输出图形的基本属性。 （6）用文件保存图形信息，且能够从文件中读取并作相应处理。 2）创新要求： 采用头文件与源文件分离的方法，多态性的实现多样化(defines an abstract base class Shape, with which it derives five categories: round, square, rectangular, trapezoidal, triangular. (2) the use of virtual functions to calculate several graphics area. Effect (3) demonstrate the constructor, copy constructor and destructor call sequence (4) with a class template implementation. (5) The use of MFC library to draw and modify graphics, using the basic properties dialog input and output graphics, or the use of the basic properties of operator overloading the input and output graphics on the graphical user interface. (6) with the file save graphical information, and can be read a file and make the appropriate treatment. 2) Innovation requirements: Using the method header and source files separate polymorphism diversify )

说明：  仿WINDOWS里面的画图程序,只做了部分模仿,还差一部分未完成(imitation windows inside the drawing program, doing some copying, there is still some unfinished)

说明：  一个动态链接库的例子 一个动态链接库的例子 一个动态链接库的例子(a dynamic link library example of a dynamic link library examples of a dynamic link for example)

本程序利用MFC树形工具控件实现各种形式的转换，可直接运行。(This program makes use of MFC tree tool control the conversion of various forms, can be run directly.)

非常重要的界面编程，很不容易编写出来的代码，可实现美化界面的作用，VC学习的好代码(aa)

list控件的基本适应方法，简单易懂。。很适合初学者(The basic adaptation list controls, easy to understand. . It is suitable for beginners)

很漂亮的代码雨，为什么一定要20字啊，好无赖啊(The code is very beautiful rain, why must 20 words, ah, ah good rogue)
