本实验通讯录主要要实现添加、删除、浏览、统计、查找等功能。完成本实验文档中有大量的数据需要存取，因此需要定义大量的成员变量来完成。在MFC中为我们提供了集合类，我们可以用它来动态的处理不同类型的对象。因此，该实验要创建一个基于SDI单文档的应用程序框架，视图类基类为CformView-In this study, mainly to achieve the contacts to add, delete, browse, statistics, search and other functions. Completion of this study document a large number of data need to access, so you need to define a large number of member variables to complete. MFC for us in the collection class, we can use it to dynamically handle different types of objects. Therefore, the experiment to create a single document based SDI application framework, the view class base class for CformView
