m_ListCtrl->InsertColumn(0,_T("Name"),0,130);
	LPSERVER_INFO_101 pBuf = NULL;
	LPSERVER_INFO_101 pTmpBuf;
	DWORD dwLevel = 101;
	DWORD dwPrefMaxLen = MAX_PREFERRED_LENGTH;
	DWORD dwEntriesRead = 0;
	DWORD dwTotalEntries = 0;
	DWORD dwTotalCount = 0;
	DWORD dwServerType = SV_TYPE_ALL; // all servers
	DWORD dwResumeHandle = 0;
	NET_API_STATUS nStatus;
	wchar_t *pszServerName = NULL;
	DWORD i;	//
	pszServerName = L"\\\\cgdomain.com"; // replace it with yours
	nStatus = NetServerEnum(pszServerName,dwLevel,(LPBYTE *) &pBuf,dwPrefMaxLen,&dwEntriesRead,&dwTotalEntries,dwServerType,NULL,&dwResumeHandle);
	if ((nStatus == NERR_Success) || (nStatus == ERROR_MORE_DATA))
	{
		if ((pTmpBuf = pBuf) != NULL)
		{	
			for (i = 0; i < dwEntriesRead; i++)
			{
				if (pTmpBuf == NULL)
				{
					break;
				}
				char szTxt[MAX_PATH]={0};
				::WideCharToMultiByte( CP_ACP, 0,pTmpBuf->sv101_name,-1, szTxt,MAX_PATH, NULL, 0);
				CString strValue,strTemp1,strTemp2;
				strValue=szTxt;
				strTemp1=strValue.GetAt(0);
				strTemp2=strValue;
				strTemp2.Delete(0);
				strTemp2.MakeLower();
				strValue="";
				strValue=strTemp1+strTemp2;				
				m_ListCtrl->InsertItem(i,strValue);
				pTmpBuf++;
				dwTotalCount++;
			}
		}
	} 
	else
		AfxMessageBox(_T("A system error has occurred"));
	if (pBuf != NULL)
		NetApiBufferFree(pBuf);

推荐答案

您需要检索正在运行应用程序的系统的网络掩码，然后获取IP地址，然后遍历所有可能的IP，向每个可能的IP发送一个ICMP数据包(基于netmask/IP).

You need to retrieve the net mask of the system you''re app is running on, then the IP address, and then iterate through all the possible IPs send an ICMP packet to each possible IP (based on netmask/IP).
