建议找些聊天室的程序来看看，对初学者来说非常适合。
至于聊天室的程序网上遍地都是，随便一搜就一大堆，就不用我给你找个发了吧：）

server端的代码
//#include <winsock2.h>
#include <winsock.h>
#pragma comment(lib, "ws2_32.lib")
int main()
{
WSADATA wsa;
struct sockaddr_in addr, from;
char buf[0x100];
SOCKET s;
int ch = 0;
int recv_len;
int len = sizeof(struct sockaddr);
WSAStartup(0x101, &wsa);
s = socket(AF_INET, SOCK_DGRAM, 0);
addr.sin_family = AF_INET;
addr.sin_port = htons(9000);
addr.sin_addr.s_addr = htonl(INADDR_ANY);
bind(s, &addr, sizeof(addr));
ch = getch();
while(1)

if ((recv_len = recvfrom(s, buf, 0x100, 0, &from, &len)) != SOCKET_ERROR)

printf("%d\n", recv_len);
//if(recv_len)

}

printf("error: %d", WSAGetLastError());

closesocket(s);
WSACleanup();
}
稍微改改就可以用了……
