楼主你好,你所指的那个指令就是"winchat",Windows自带的局域网聊天工具.使用方法:开始--运行--输入winchat,就可以打开Winchat了.只能实现很简单的功能,并且是中文,没什么好介绍的,相信你一看就懂,希望可以帮到你!
ps:你所说的电影是杜拉拉升职记吧?貌似那是用的邮件发的,不小心点成群发了~嘿嘿..
用VB5 Winsock控件创建TCP/IP通讯程序 随着Windows 95中文版和Windows NT Server 4.0中文版的流行， Microsoft公司推出了相应平台上的开发软件: Visual Basic 5.0 中文企业 版。它为Windows环境下的网络开发提供了强大的工具，Winsock控件就是其中之一。 Winsock控件建立在TCP、UDP协议的基础上，完成与远程计算机的通信。即使对TCP/IP不太熟悉的用户，使用该控件也可以在十几分钟内创建一个简单的客户机/服务器程序。下面我们对Winsock控件的事件、方法、属性按其在程序中出现的顺序分别作详细的介绍，以便更好地理解程序源代码。
