VB.NET 如何实现局域网内即时会话

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!

VB.NET中能否做一个像QQ那样的聊天框，可以输入文字和图片？

第一个问题 qq聊天室 必须能 用vb都可以做

第二个问题 vb.net插入数学公式 可以把这些公式封装到一个类中，调用就是了

请问一下大虾们(vb.net) socket 作为聊天服务器（固定ip），客户端连接服

Server端不是要建立serversocket么，这个类会监听socket连接，客户端连接服务端的时候会携带本机（客户端）的ip，服务器接收连接，经过三次握手之后双方建立tcp连接，然后就可以通讯了，编写服务端的时候并不需要关心客户端发起连接的端口。

获取ip：socket.getInetAddress()

获取端口:socket.getPort();
