socket 问题 win98 与 win2000是如此的不同。

[gpg]

我有一文件传输程序，基于winsock写的。9x与9x可以，2000与2000也是好的。
但2000向98传或98向2000传就不行了。怎么回事啊？

看一看是不是UNICODE的问题。
13. 如何在Unicode与ANSI之间转换字符串？
Windows函数MultiByteToWideChar用于将多字节字符串转换成宽字符串；函数WideCharToMultiByte将宽字符串转换成等价的多字节字符串。

xiaoxiaohan 不是的。
另，我没有用任何组件。

我用的是 Berkeley Socket风格

我做的没有问题，不知你用的Socket如何实现的，API,TcustomSocket,Tpowersocket?

[LuoGD]

我用API做的没问题,WINDOWS<--->UNIX也可以
