Socket2实现tcp端口扫描

主要的界面如下：

主要代码如下：

 //对于每一个线程，传过去的参数
 typedef struct ThreadParamStruct
 {
     CString strIP;            //要扫描的IP地址
     UINT  uPort;            //要扫描的端口
     BOOL  bNoOrder;            //是否按照随机的顺序扫描
     CPortScan_TCPDlg *ptr;    //指向父线程的对话框
     HTREEITEM TreeItem;        //指向结果要显示的树型控件节点
 }THREADPARAM;

 UINT ThreadCSocket2Scan(LPVOID pParam)
 {
     THREADPARAM *threadparam = (THREADPARAM*)pParam;
     CString strIP = threadparam->strIP;
     UINT uPort = threadparam->uPort;
     CPortScan_TCPDlg *ptr = threadparam->ptr;
     HTREEITEM TreeItem = threadparam->TreeItem;
     BOOL bNoOrder = threadparam->bNoOrder;

     g_iTotalThreadCount++;
     if (bNoOrder)
     {
         Sleep(rand() % );
     }

     SOCKET sock = -;
     sock = socket(AF_INET, SOCK_STREAM, );
     if (sock == SOCKET_ERROR)
     {
         return ;
     }

     int iTimeOut = ;
     if (SOCKET_ERROR == setsockopt(sock, SOL_SOCKET, SO_SNDTIMEO, (TCHAR*)&iTimeOut, sizeof(iTimeOut)))
     {
         g_iTotalThreadCount--;
         closesocket(sock);
         return ;
     }
     iTimeOut = ;
     if (SOCKET_ERROR == setsockopt(sock, SOL_SOCKET, SO_RCVTIMEO, (TCHAR*)&iTimeOut, sizeof(iTimeOut)))
     {
         g_iTotalThreadCount--;
         closesocket(sock);
         return ;
     }

     SOCKADDR_IN addr_remote;
     addr_remote.sin_family = AF_INET;
     addr_remote.sin_addr.S_un.S_addr = inet_addr(strIP);
     addr_remote.sin_port = htons(uPort);
     if ( != connect(sock, (PSOCKADDR)&addr_remote, sizeof(addr_remote)))
     {
         g_iTotalThreadCount--;
         closesocket(sock);
         return ;
     }

     CString strTemp;
     if (uPort < )
     {
         struct servent *se;
         se = getservbyport(htons(uPort), _T("tcp"));
         if (se != NULL)
         {
             strTemp.Format(_T("%d %s"), uPort, se->s_name);
         }
         else
         {
             strTemp.Format(_T("%d"), uPort);
         }
     }
     else
     {
         strTemp.Format(_T("%d %s"), uPort, ptr->GetPortName(uPort, TRUE));
     }
     ptr->m_wndTreeResult.InsertItem(strTemp, , , TreeItem);

     shutdown(sock, );
     closesocket(sock);
     g_iTotalThreadCount--;
     return ;
 }

 CString CPortScan_TCPDlg::GetPortName(UINT uPort, BOOL bIsTCP)
 {
     CString strRet;
     if (bIsTCP)
     {
         switch (uPort)
