引言

我提供了一个类 CxNetCardInfo，它可以用来获取本地机器网卡适配器信息，例如IP地址、MAC地址、DHCP、子网掩码、WINS等。有关更详细的信息，请参阅下一节。

如何使用 CxNetCardInfo

CxNetCardInfo 的使用很简单！例如

void CNetCardInfoDlg::OnButtonGetinfo() 
{
  // TODO: Add your control notification handler code here
  CString tmp( _T("") );

  CxNetCardInfo NCI;

  tmp += _T("NetCard type:\t") + NCI.GetNetCardType() + _T("\r\n");
  tmp += _T("IP Address:\t") + NCI.GetNetCardIPAddress() + _T("\r\n" );
  tmp += _T("Subnet Mask:\t") + NCI.GetNetCardSubnetMask() + _T("\r\n");
  tmp += _T("Gateway:\t") + NCI.GetNetCardGateWay() + _T("\r\n");
  tmp += _T("DHCP Server:\t") + NCI.GetDHCPServer() + _T("\r\n");
  tmp += _T("MAC Address:\t") + NCI.GetNetCardMACAddress() + _T("\r\n");
  tmp += _T("Device name:\t") + NCI.GetNetCardDeviceName() + _T("\r\n");
  tmp += _T("Wins Server:\t") + NCI.GetNetCardWINS() + ("\r\n");
  tmp += NCI.GetErrorMsg() + _T("\r\n");

  CEdit *pEdit = (CEdit *)GetDlgItem(IDC_EDIT_INFO);
  pEdit->SetWindowText(tmp);
}

注释

CxNetCardInfo 类不够健壮，无法用于严肃的应用，但希望有人可以修改它并使其更好！
