This code to find the MAC address of a PC connected to the internet.
What's a sName in the code?
public class GetMacAddressFromIPAddress
{
[DllImport("iphlpapi.dll", ExactSpelling=true)]
public static extern int SendARP( int DestIP, int SrcIP, [Out] byte[] pMacAddr, ref int PhyAddrLen );
public string GetMacAddress(string sName)
{
string s = string.Empty ;
System.Net.IPHostEntry Tempaddr = null;
Tempaddr = (System.Net.IPHostEntry)Dns.GetHostByName(sName);
System.Net.IPAddress[] TempAd = Tempaddr.AddressList;
string[] Ipaddr = new string[3];
foreach(IPAddress TempA in TempAd)
{
Ipaddr[1] = TempA.ToString();
byte[] ab = new byte[6];
int len = ab.Length;
int r = SendARP( (int) TempA.Address, 0, ab, ref len );
string sMAC = BitConverter.ToString( ab, 0, 6 );
Ipaddr[2] = sMAC;
s = sMAC;
}
return s;
}
}

And this case , it's the internet ip address and not the pc ip address, isn't it?
2nd thing is that, when using this code, how to suppply internet address for it, do I have to get a code to detect the internet ip address and then pass it to the MAC Function?
THanks

Hi,
Is it that IIS spawn a seperate worker process for all FTP requests, one for all HTTP requests, one for other
message based requests
or is it that there is only one worker process in totality and there can be any number of application domains no matter
whether the request is FTP, HTTP or any message based requests
Thanks,

After implementing a CSS template to my web site i am getting the following error while running. "Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. "
I searched a lot in net and found some solutions which did not worked for me. But my actual problem is the same code is working in another browser. I am getting the error while i am using IE. What is the reason and solution???

For .xlsx files I think u will need another connection string
Provider=Microsoft.ACE.OLEDB.12.0;Data Source=filename.xlsx;Extended Properties=Excel 12.0;
u can also Add HDR property to connection string
Provider=Microsoft.ACE.OLEDB.12.0;Data Source=filename.xlsx;Extended Properties=Excel 12.0;HDR=YES;
HDR=YES --> implies that the file has header info in the 1st Row
Try this let me know if it works or not

The obvious question is why not add the runat attribute?
I know the language. I've read a book. - _Madmatt
|
|
|
|
|
if i did add runat="server" i can access mydiv.innerText from .cs page.
please let me know if any way to access that.
|
|
|
|
|
When you add a runat=server attribute to an html element it is automatically wrapped as a HtmlGenericControl. Your first attempt gained you nothing.
So rather than this
HtmlGenericControl div = (HtmlGenericControl)Page.FindControl("mydiv");
if (div != null)
{
div.InnerHtml = "test message";
}
You could have this
div.InnerText = "test message";
