关于SOCKET编程

以下是一个通HTTP下载文件的程序,但总是在CONNECT时不成功,请问为什么?
  char fname[MAXPATH];     void LogFile(char *p)   {             FILE *fp=fopen(fname,"a+");             fprintf(fp,"%s\n",p);             fclose(fp);   }       BOOL HttpClient(void)   {             WSADATA ws;             SOCKET s;             struct sockaddr_in addr;               int iResult;             long lResult;             char strSubAddr[100], strBuffer[100];               lResult = WSAStartup(0x0101,&ws);             s = socket(AF_INET,SOCK_STREAM,0);               addr.sin_family = AF_INET;             addr.sin_port = htons(80);             addr.sin_addr.s_addr = inet_addr            ("168.160.224.185"); // 计算机世界日报             iResult=connect(s,(struct sockaddr *) &addr, sizeof(addr));             if(SOCKET_ERROR == iResult)             {                     // 连接失败                     WSACleanup();                     return FALSE;             }             else {                     // 连接成功             strcpy(strSubAddr, "GET /99/tips/ \r\n");            strcpy(fname, "index.htm");            iResult = send(s, strSubAddr,strlen(strSubAddr),0);                       // 下载文件                     do {                             strset(strBuffer,' ');            iResult = recv(s,strBuffer,sizeof(strBuffer),0);               LogFile(strBuffer);                     } while( iResult !=0 );             }               WSACleanup();             return TRUE;   }
