To check whether a computer has a working connection

  • Determine whether the IsAvailable property is True or False. The following code checks the property's status and reports it:

    If My.Computer.Network.IsAvailable = True Then
    MsgBox("Computer is connected.")
Else
    MsgBox("Computer is not connected.")
End If
