And it involved this very issue. And a Senior MS Consultant (I hate to admit) showed me the path towards righteousness. Basically, your MAC address gets replaced with each frame along each router or some such non-sense. Meaning that outside your local network the MAC is meaningless. Much worse, some TCP/IP stacks do not even provide it through the API so you would need to really write some code to get it.

In case of ASP.NET it is a client server architecture.. So you can only get things that are sent through request object.
As every request is made by the browser (client) you can add the mac address to it and send it.
So only option is your IP.... which is also the external one.

Hi,try to do this.
using System.Management;
string stringMAC = "";
string stringIP = "";
ManagementClass MC = new ManagementClass "Win32_NetworkAdapterConfiguration");
ManagementObjectCollection MOC= MC.GetInstances();
foreach(ManagementObject MO in MOC)
{
if ((bool)MO["IPEnabled"] == true)
{
stringMAC += MO["MACAddress"].ToString();
TextMAC.Text = stringMAC.ToString();
string[] IPAddresses = (string[]) MO["IPAddress"];
if(IPAddresses.Length > 0)
stringIP = IPAddresses[0];
TextIP.Text = stringIP.ToString();
}

Hi, you can refer to the following code:
[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 Page_Load(object sender, System.EventArgs e)
{
// initial page
try
{
string userip=Request.UserHostAddress;
string strClientIP = Request.UserHostAddress.ToString().Trim();
Int32 ldest = inet_addr(strClientIP); //client ip
Int32 lhost = inet_addr(""); //server ip
Int64 macinfo = new Int64();
Int32 len = 6;
int res = SendARP(ldest,0, ref macinfo, ref len);
string mac_src=macinfo.ToString("X");
if(mac_src == "0")
{
if(userip=="127.0.0.1")
Response.Write ("Localhost!");
else
Response.Write ("welcome IP = " + userip + "<br>");
return;
}
while(mac_src.Length<12)
{
mac_src = mac_src.Insert(0,"0");
}
string mac_dest="";
for(int i=0;i<11;i++)
{
if (0 == (i % 2))
{
if ( i == 10 )
{
mac_dest = mac_dest.Insert(0,mac_src.Substring(i,2));
}
else
{
mac_dest ="-" + mac_dest.Insert(0,mac_src.Substring(i,2));
}
}
}
Response.Write ("welcome IP = "+userip+ "<br>" + ",MAC = "+mac_dest
+ "<br>");
}
catch(Exception err)
{
Response.Write(err.Message);
}
}

Hi all,
I need to add more data separated by commas in one cell in a Gridview. I capture the data from the textboxes and save into the Gridview but for Cas No textbox, I need to add more than one value.I have another Add button next to this textbox to add more data. I don't know how to do achieve this. I'd appreciate any help/advice.
Here is my Code:
private void DataBindGridCases()
{
try
{
DateTime date = new DateTime();
//Create DataTable.
DataTable dt = (DataTable)Session["dtCaseDetails"];
if (dt == null)
{
//Create DataTable.
dt = new DataTable();
//Assign Columns to it.
dt.Columns.Add(new DataColumn("Province"));
dt.Columns.Add(new DataColumn("City"));
dt.Columns.Add(new DataColumn("Station"));
dt.Columns.Add(new DataColumn("Cas No"));
dt.Columns.Add(new DataColumn("Investigating Officer"));
dt.Columns.Add(new DataColumn("Name of Court"));
dt.Columns.Add(new DataColumn("Date"));
}
//Create a DataRow by dt.NewRow().
DataRow dr = dt.NewRow();
if (chkCourtDate.Checked)
{
//Fill that row and add it to datatable.
dr["Province"] = txtProvince2.Text;
dr["City"] = txtCity.Text;
dr["Station"] = txtStation.Text;
dr["Cas No"] = txtCasNo.Text;
dr["Investigating Officer"] = txtInvestOfficer.Text;
dr["Name of Court"] = txtNameOfCourt.Text;
DateControl.PopulateEntity(ref date);
dr["Date"] = date;
dt.Rows.Add(dr);
}
else
{
dr["Province"] = txtProvince2.Text;
dr["City"] = txtCity.Text;
dr["Station"] = txtStation.Text;
dr["Cas No"] = txtCasNo.Text;
dt.Rows.Add(dr);
}
Session["dtCaseDetails"] = dt;
//Bind GridView Here with this Table
this.BindDataCase();
//clear the textboxes
this.ClearTextboxes();
//Rename the button
btnSave.Text = "Add Another Case";
}
catch (Exception ex)
{
Response.Write(ex.Message);
}
}
private void BindDataCase()
{
//Bind GridView Here with this Table
this.dgCaseDetails.DataSource = Session["dtCaseDetails"];
this.dgCaseDetails.DataBind();
}
Thank you in advanced.

Append the value from the textbox to the column in the data datatable. What are you having difficulty with?

The code is following, I need to count how much bandwidth that this program uses.
struct soap soapService;
soap_init(&soapService);
soapService.accept_timeout = 60;
soapService.recv_timeout = 60;
soapService.send_timeout = 60;
soapService.connect_timeout = 60;
int result = -1;
_ns1__QueryPerson queryPerson;
_ns1__QueryPersonResponse *queryPersonResponse;
const char* s1 = "fish";
std::string stdstr(s1);
queryPerson.name = &stdstr;
queryPersonResponse = new _ns1__QueryPersonResponse();
const char* server = "http://192.168.140.127/classmate/Service.asmx";
result = soap_call___ns2__QueryPerson(&soapService, server, "", &queryPerson, queryPersonResponse);
if(soapService.error)
{
soap_print_fault(&soapService,stderr);
result = soapService.error;
}
if (result == SOAP_OK)
{
cout <<"收到数据:[" << endl;
}
else
{
printf("soap error ,errcode = %d\n", result);
}
soap_destroy(&soapService);
soap_end(&soapService);
soap_done(&soapService);
delete queryPersonResponse;

Hi friends
I have created a gridview using ITemplate to generate textboxes in cells and to display the data. The grid is bound using a datatable in PreRender event.
On Page refresh the modified value gets replaced by the existing value from datatable. If I do not bind the gridview in each refresh, the textboxes gets vanish from the gridview.
Can any one help me to overcome this problem.
Does viewstate will have any role in this?
Thanks in advance

That's right. If there is no value, the gridview will disappear from gui.
You can try to set EnableViewState="false".

Thanks for you reply.
Is there any event in which, the typed value on the textbox is accessible? So that I can update the data table from that. Then on rebinding I will get the last typed value again.
Thanks

Hi
am using a dll in my web project ("Owc11.dll")
Before upgrading our production server (32 bit) it was working fine. So, recently
our production server has been upgraded to 64 bit. So, while running the
application one error throwing like this:
"retrieving the COM class factory for component with CLSID {0002E55D-0000-0000-C000-000000000046} failed due to the following error: 80040154"
Thanks & Regards,

I dont think this dll would work for 64 bit machine.This issue is also faced by other ones also..

Yes, it willn't work in 64 bit machine. Do you know, any solutions for this ?
Thanks & Regards,

You have to make your web app run under 32 bit explicitly or it will not be able to call Owc11.dll ie. Compile it to target x86 cpu.
You will also have to set Enable32BitAppOnWin64 in IIS for the application pool that the web application uses. I think the ManagedPipelineMode on the appPool should be set to false as well.

How can we compile a dll ? we are using a thrid party dll, we dont have the source code for the dll.
Also, we are using IIS 6.0 in windows 2003 server. If we set Enable32BitAppOnWin64 on IIS
6, every applications hosted in IIS 6.0 will work in 32 bit. Applications in IIS 6.0 will
not support both modes simultaneously, right ?
Thanks & Regards,

I have deploy my web application in IIS 7.0 and I get below error
HTTP Error 404.3 - Not Found
The page you are requesting cannot be served because of the extension configuration. If the page is a script, add a handler. If the file should be downloaded, add a MIME map.
It is possible that a handler mapping is missing. By default, the static file handler processes all content.
The feature you are trying to use may not be installed.
The appropriate MIME map is not enabled for the Web site or application. (Warning: Do not create a MIME map for content that users should not download, such as .ASPX pages or .config files.)
If ASP.NET is not installed.

IIS7 is not configured properly.
pls configure that one correctly and deploy it.
