connect一直连接不上，求大虾们帮帮忙！

有没有初始化SOCKET库？

另外这个地改一下
addrclient.sin_addr.s_addr = htonl(inet_addr( "127.0.0.1" ));
改成
addrclient.sin_addr.s_addr =inet_addr( "127.0.0.1" )

你的sever的ip地址设置成127.0.0.1了吗

一般写网络程序，如果winsocket 函数调用失败，利用WSAGetLastError看看返回值是什么，就知道了错误的原因了

1楼的大神说的不错，3楼大神的方法可以验证验证，还有一点就是把客户端的端口设置语句改为ntohs(5000)

谢谢大家的回答 ，是zhouzhipen(血狼)的方法～

addrser.sin_addr.s_addr = htonl(INADDR_ANY);
--------------------------------------------
这句改一下：
addrser.sin_addr.S_un.s_addr = inet_addr( "127.0.0.1" );
