	protected static string strJavaScript = string.Empty;
	[DllImport("Iphlpapi.dll")]
	private static extern int SendARP(Int32 dest, Int32 host, ref Int64 mac, ref Int32 length);
	[DllImport("Ws2_32.dll")]
	private static extern Int32 inet_addr(string ip);

	

	private void SetMac()
	{
	try
	{
	string treatment_id = Hid_treatment_id.Value;
	string mac = string.Empty;

	string ip = Request.UserHostAddress.ToString().Trim();
	try
	{
	mac = getMac();
	}
	catch { lbl.InnerText = "w33w"; }
	//mac = "00:01:36:D8:9C:C4";
	// lbl.InnerText = mac + "," + ip;
	if (mac != "您没有联网")
	{
	int iRetn = commonws.GetInt("CRRT/PAD-登录", "指定某治疗病人的平板MAC地址", new string[] { mac, treatment_id });
	}
	}
	catch { lbl.InnerText = "ww"; }
	}

	private string getMac()
	{
	string mac = "";
	string strClientIP = Request.UserHostAddress.ToString().Trim();
	Int32 ldest = inet_addr(strClientIP); //目的地的ip
	Int32 lhost = inet_addr(""); //本地服务器的ip
	Int64 macinfo = new Int64();
	Int32 len = 6;
	int res = SendARP(ldest, 0, ref macinfo, ref len);
	mac = macinfo.ToString("X");
	try
	{
	string[] arr_mac = new string[mac.Length / 2];
	int k = 0;
	for (int i = mac.Length; i > 0; i = i - 2)
	{
	arr_mac[k] = mac.Substring(i - 2, 2);
	k++;
	}
	mac = "";
	foreach (string chars in arr_mac)
	{
	mac += chars + ":";
	}
	mac = mac.TrimEnd(':');
