I'm using the following code to get the MAC Address from the PC. The actual
MAC Address of the PC is 8th and 9th in the list (following the code). How
do I get just the MAC Address I need? Why are there so many entries?


Dim objManagementClass As New ManagementClass(New
ManagementPath("Win32_NetworkAdapter"))

Dim colManagementObjects As ManagementObjectCollection =
objManagementClass.GetInstances

For Each objMO As ManagementObject In colManagementObjects

    Me.lstGeneric.Items.Add(IIf(IsNothing(objMO("MACAddress")), "Nothing",
objMO("MACAddress")))

Next

Output from the code is:

Nothing
20:41:53:59:4E:FF
Nothing
50:50:54:50:30:30
33:50:6F:45:30:30
Nothing
Nothing
00:0D:61:26:94:C8
00:0D:61:26:94:C8
62:FF:20:52:41:53
Nothing

Thanks,
Michael

I suggest you look at some of the other attributes to filter out what you
want, such as AdappterType. You're seeing all the network providers
available. What you want is something like a NetConnectionID value of "Local
Area Cionnection".

Thanks for you help. I acutally used IPEnabled to filter. Seems to work.
