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();
VB.NET即时窗口快捷键
VB.NET即时窗口用于在设计时调试和计算表达式、执行语句、输出变量值等
快捷键是:CTRL+G 或者按 CTRL+ALT+I
