CSocket实现端口扫描

界面如下：

主要代码如下：

1 //对于每一个线程，传过去的参数

2 typedef struct ThreadParamStruct

3 {

4     CString strIP;            //要扫描的IP地址

5     UINT  uPort;            //要扫描的端口

6     BOOL  bNoOrder;            //是否按照随机的顺序扫描

7     CPortScan_TCPDlg *ptr;    //指向父线程的对话框

8     HTREEITEM TreeItem;        //指向结果要显示的树型控件节点

9 }THREADPARAM;

 1 UINT ThreadCSocketScan(LPVOID pParam)

 2 {

 3     THREADPARAM *threadparam = (THREADPARAM*)pParam;

 4     CString strIP = threadparam->strIP;

 5     UINT uPort = threadparam->uPort;

 6     CPortScan_TCPDlg *ptr = threadparam->ptr;

 7     HTREEITEM TreeItem = threadparam->TreeItem;

 8     BOOL bNoOrder = threadparam->bNoOrder;

 9 

10     g_iTotalThreadCount++;

11     if (bNoOrder)

12     {

13         Sleep(rand() % 3000);

14     }

15 

16     CSocket sock;

17     CString strTemp;

18     if (sock.Create())

19     {

20         if (sock.Connect(strIP, uPort))

21         {

22             if (uPort < 1024)

23             {

24                 struct servent *se;

25                 se = getservbyport(htons(uPort), _T("tcp"));

26                 if (se != NULL)

27                 {

28                     strTemp.Format(_T("%d %s"), uPort, se->s_name);

29                 }

30                 else

31                 {

32                     strTemp.Format(_T("%d"), uPort);

33                 }

34             }

35             else

36             {

37                 strTemp.Format(_T("%d %s"), uPort, ptr->GetPortName(uPort, TRUE));

38             }

39 

40             ptr->m_wndTreeResult.InsertItem(strTemp, 2, 2, TreeItem);

41             sock.ShutDown(2);

42         }

43         sock.Close();

44     }

45 

46     g_iTotalThreadCount--;

47     return 0;

48 }

 5     {

 6         switch (uPort)

 7         {
