那位大虾能提供有关实现 局域网文字聊天、语音聊天、文件传输的源代码(20分)

那位大虾能提供有关实现 局域网文字聊天、语音聊天、文件传输的源代码。
类似QQ。

文件传输的源代码： http://www.delphifans.com/down_view.asp?id=430

才20分，怎么可以打动人哦！该叫您老大拉！！

文字聊天跟文件传输是一样的，只是文件用的是流，而聊天用的是纯文本，有关的代码你去看一下文件传输的有关DEMO吧，到处都是～

我也只能说这么多了，毕竟，20分是少了点～嘿嘿～

不要嫌少了，我就这么一点了。可怜可怜我这个小乞丐吧！

看一下nmudp的使用方法，delphi帮助里有，这个能实现文字聊天、文件传输。
而语音聊天是在实现文字聊天的基础上，将传输文本换成声音。但是声音的处理就比较麻烦了，我现在只能处理单机对单机通话。
如果有需要，可以发个给你，asdc@263.net

我好像有一个，如果要的话给我发e-mail:n_sg@tom.com我帮你找找
戴源代码的

俺的原创：

我这里有了局域网聊天的源码，看上去也不是很复杂，只是很希望有一个功能比较的完备的相关源码进行研究。恳请大家多提供一些相关的信息。

网上都缺少synsock和bl*sock单元文件
运行不了,核心部分都没有

//Msg的格式：
//前15位是本机IP地址，虽然FromIP包含了发信息方的IP，但是如果有代理服务器的话，
//这个IP有时是代理服务器的IP；
//16-21是信息标识：
// 'Login' --上线信息
// 'Logout'--离线信息
// 'Broad' --广播信息
// 'Chat' --聊天信息
//从22位起就是实际信息
