VB.NET 如何實(shí)現(xiàn)局域網(wǎng)內(nèi)即時(shí)會(huì)話

樓主你好,你所指的那個(gè)指令就是"winchat",Windows自帶的局域網(wǎng)聊天工具.使用方法:開始--運(yùn)行--輸入winchat,就可以打開Winchat了.只能實(shí)現(xiàn)很簡(jiǎn)單的功能,并且是中文,沒什么好介紹的,相信你一看就懂,希望可以幫到你!

ps:你所說的電影是杜拉拉升職記吧?貌似那是用的郵件發(fā)的,不小心點(diǎn)成群發(fā)了~嘿嘿..

VB怎樣局域網(wǎng)語音聊天啊？

就是用direct技術(shù)獲得聲卡的話筒的信號(hào)，形成二進(jìn)制流，再通過TCP或UDP傳送到對(duì)方。對(duì)方用聲卡播放。

VB.NET容易做局域網(wǎng)簡(jiǎn)單的聊天工具嗎？用TCP協(xié)議
