关于在Delphi中使用VB的WinSock控件的一些问题(200分)

我现在需要在Delphi中使用VB的WinSock控件,我发现似乎服务器端的控件和客户端的控件
必须成对出现,如果服务器端用的是Delphi的ServerSocket则客户端必须用ClientSocket,
同样,如果客户端用的是VB的WinSock,则服务器端用ServerSocket也会出错.不知道是不是
这样,希望各位大侠指教.
另外,在Winsock的OnDataArrival中,如何调用Winsock控件的GetData方法?我用什么变量
都会报错.谢谢!

1、服务器端用SERVERSOCKET，客户端用WINSOCK控件没问题，我已顺利实现通讯；
2、WINSOCKE的GETDATA需要OLEVARIANT类型的参数，它是一个变长BYTE类型的数组，你要自己
转换，也可以把它先保存到BUFFER中，逐一分析执行；
3、在这例子中，还动态调用ActiveX：MSWINSOCK.WINSOCK.1并设置参数，也可实现收发功能；

以下是我以前的一个例子，照原样贴出来，只要能看清是怎么来着就行，若有问题请E：
