谢谢大家！其余代码略

啊!这不就是个对话框吗?呵呵,楼主啊,对话框还是先找到几个主要函数吧
这里呢有afx_msg void OnAdd();
afx_msg void OnDel();
virtual BOOL OnInitDialog();
afx_msg void OnSelchangeList1();
virtual void OnOK();
afx_msg void OnMod();
几个函数是比较重要的,从字面上看有一个初始化函数 OnInitDialog();还有一个下拉列表框afx_msg void OnSelchangeList1();记住一点,这个对话框的初始化都是从 OnInitDialog()开始的,其他的部分请打开msdn对照着on_command宏来观察消息的流向,这个就会很清楚了.
