## Description Use the `NetworkInterface` object to obtain networking information about the user's computer. ## Notes Use the optional parameter to specify the network interface card. *Index* is zero-based. If *Index* is out of bounds, an `OutOfBoundsException` is raised. NetworkInterfaceCount gives you the number of network interfaces in the computer. ## Sample code The following simple example displays the IP address, Subnet mask, and Mac address for the selected network interface. At start-up, the application detects all the network interfaces installed on the user's computer and loads them into a `PopupMenu`. The user then selects the desired network interface and the values are displayed in `TextFields`. The `PopupMenu's` Open event handler is: ``` xojo For i As Integer = 0 To System.NetworkInterfaceCount - 1 PopupMenu1.AddRow(Str(i)) Next ``` --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- The Change event handler for the `PopupMenu` is this: ``` xojo Sub Change() If Me.ListIndex > -1 Then ' Get the NetworkInterface object for the selected item Dim iface As NetworkInterface = System.GetNetworkInterface(Me.ListIndex) MacAddressField.Text = iface.MACAddress IPAddressField.Text = iface.IPAddress SubnetMaskField.Text = iface.SubnetMask End If End Sub ``` ## Compatibility All project types on all supported operating systems.
