没搞过sock，我系统上运行也是出你一样的错误，估计跟“重装系统”无关

建议改用群友孤独王的vfpsocket.fll，非常方便

总算自己找到问题所在了，server的connectionrequest里有句代码被注释掉了。。。

分别把sever和client拷贝到局域网不同的电脑，在表单client的init中设置一下remotehost和port就可以运行了。。。

服务端发送出错，客户端发送提示没有连接。
必须要在2台电脑上运行吗？

分别在2台电脑上运行啊

同一台电脑应该没问题。
广域局域网能连接就可以。
socket c/s 简单的用几个socket api 也可以实现。
示例：以典型的聊天代码为例，尝试 Scoket API 的 C/S。

回复 8楼 kangss

继续测试吧，同一台电脑可以成功运行并互相通讯的，我刚测试通过
