I'm trying to get a Device Unique Identifier in vb.net code. I have tried with
Private Function SystemSerialNumber() As String
Dim value As String = ""
Dim baseBoard As ManagementClass = New ManagementClass("Win32_BaseBoard")
Dim board As ManagementObjectCollection = baseBoard.GetInstances()
If board.Count > 0 Then
value = board(0)("SerialNumber")
If value.Length > 0 Then value = value.Substring(2)
End If
Return value
End Function
Which works on some computers but of the board doesn't have a serial number it returns "Default String" or whatever they put in there. Even tried with Win32_Processor and some have it and others just return "To be filled by O.E.M" lol
Also tried with,
Private Function SystemSerialNumber() As String
Dim value As String
Dim q As New SelectQuery("Win32_bios")
Dim search As New ManagementObjectSearcher(q)
Dim info As New ManagementObject
For Each info In search.Get
value = info("SerialNumber").ToString
Return value
Next
End Function
But its the same some devices have it some don't and just returns default string.
So I'm now trying is:
Private Function SystemSerialNumber() As String
Dim value As String
value = Windows.System.Profile.SystemIdentification.GetSystemIdForPublisher()
End Function
But I'm having trouble referencing to it. I tried Imports Windows.System but it just gives the error it cant be found.
As a side note I'm using this program in tablets with windows10, laptops, and desktops.
UPDATE: I'll be using as suggested by Heinzi. Thanks! Also changed variable names to be more accurate.
Private Function NetworkAdapterMacAddress() As String
Dim McAddress As String
Dim netadapter As ManagementClass = New ManagementClass("Win32_NetworkAdapterConfiguration")
Dim mo As ManagementObject
Dim adapter As ManagementObjectCollection = netadapter.GetInstances()
For Each mo In adapter
If mo.Item("IPEnabled") = True Then
McAddress = mo.Item("MacAddress").ToString()
Return McAddress
End If
Next
End Function

Well, there is no guaranteed ID that identifies every PC out there uniquely (fortunately, I might add. Privacy is a good thing).
You best bets are probably
Oh, and on a philosophical note, you might want to ponder on the Ship of Theseus.
