用Delphi写的MSN界面程序，其实用Delphi来实现界面是效率最高的。所以非常适合来开发客户端，服务器端可以考虑用Java.这个程序是我自己模仿MSN写的客户端程序。-Using Delphi to write the MSN interface procedures, in fact, to achieve the interface with Delphi is the most efficient. So well suited to the development of client, server-side may consider using Java. This process is my own MSN imitate written client program.
