classes for retriving MAC address in VB .NET

mistrypremal · April 6th, 2005, 03:25 AM

hi,

it would be great if anyone could help me out in solving this problem
I am developing an application which requires to find the MAC address of the
REMOTE computer.

I was wondering if there are any in-built classes in VB .NET to find the MAC address.

Thank You.

I am trying to do the same thing on .NET

Did anyone have any luck at all pulling this off? I am currently doing this in .NET 1.1 but may upgrade to 2.0 in the near future.

Any help would be much appreciated!

So you *have* done this or you *have not* done this? You seem to be negating your own statement. If you have done this would you like to share with the original poster how you did it?

Behavior in 2.0 will most likely be the same as in 1.1.

Sorry, I wasn't clear. I have NOT done this. If anyone has, let us know.

there is a class System.Net.NetworkInformation.PhysicalAddress that returns the mac address.. (sorry this is for .net 2, I don't know is this class exists in 1)

anyway google yield a solution for .net 1 ( I don't know if works..)

Code:

Dim mc As System.Management.ManagementClass
      Dim mo As ManagementObject
      mc = New ManagementClass("Win32_NetworkAdapterConfiguration")
      Dim moc As ManagementObjectCollection = mc.GetInstances()
      For Each mo In moc
         If mo.Item("IPEnabled") = True Then
            ListBox1.Items.Add("MAC address " & mo.Item("MacAddress").ToString())
         End If
      Next

Thanks for the help. I have tried that code before and unfortunately it only grabs the MAC address of wherever this code runs (i.e. the web server) and not from remote machines.

So it looks like System.Net.NetworkInformation.PhysicalAddress from 2.0 is my best bet.

Thanks again.

mmmm.. the other idea will not work either, it will tell you the address of your current machine...

why do you need the mac of the remote computer??

The client requested that for particular transactions, the following are to be grabbed for security purposes: IP address, machine name, Active Directory username, and MAC address.

The rest were pretty straightforward. The MAC address on the other hand...

gbianchi · August 10th, 2007, 12:12 PM

mmm.. if you are on a intranet, maybe there is another way to retrieve that info...

but if you are trying to log user activity, maybe better use an activity log...
