Obtaining MAC Address

[TheBoy]

Hi. I am using VB6 and need to obtain the MAC address of the network card in my computer. The end result I would like is simply a label which displays the MAC address of the network card.

I have looked on the net already and found lots of very complicated code which I think maybe not what I need anyway.

Any help is appreciated

This would work. This code uses WMI calls to get the computer information. This section of code will get the mac address of the network card that is in use that the time.

Public Sub GetWMIAdapter()
Dim oAdapters As Object
Dim oAdapter As Object

On Error Resume Next

Set oAdapters = GetObject("winmgmts:").ExecQuery( _
    "SELECT * FROM Win32_NetworkAdapterConfiguration WHERE IPEnabled = True")
    
For Each oAdapter In oAdapters
    With oAdapter
         Label1.Caption "MAC:" & vbTab & vbTab & .MACAddress
    End With
Next
End Sub

Hi Wiccaan

Ive done this sujestion:

Private Sub Command1_Click()
Call GetWMIAdapter
End Sub

Public Sub GetWMIAdapter()
Dim oAdapters As Object
Dim oAdapter As Object

On Error Resume Next

Set oAdapters = GetObject("winmgmts:").ExecQuery( _
    "SELECT * FROM Win32_NetworkAdapterConfiguration WHERE IPEnabled = True")
    
For Each oAdapter In oAdapters
    With oAdapter
         Label1.Caption "MAC:" & vbTab & vbTab & .MACAddress
    End With
Next
End Sub

I get a compile error which says invalid use of property and highlights .caption

Im a noob to all this VB sorry if its a silly question

[TheBoy]

I think you need to change the line:

Label1.caption "MAC ...
to
Label1.caption = "MAC ...

As TheBoy pointed out... it was missing the '=' that was my fault. Sorry about that, but it should work.

Cheers guys, silly me, im a noob

Heres one for you wiccaan,

I need to write some code that can do a tracert www.yahoo.com (any url) and save the first Hop ip address.

Can this be done?

cheers

You could shellexecute tracert.exe passing the correct parameters and output to a textfile. Then read the file into your program.

tracert -d -h 1 > C:\OneHop.txt www.yahoo.com

Tracing route to www.yahoo.akadns.net [66.94.230.32]

over a maximum of 1 hops:



  1    <1 ms    <1 ms    <1 ms  192.168.1.1 



Trace complete.
