Class MessageFilter
    Implements IMessageFilter

                Case WM_KEYDOWN, WM_MOUSE_LEFT_CLICK
                    ' Do something to indicate the user is still active.

                    Exit Select
            End Select

            ' Returning true means that this message should stop here,
            ' we aren't actually filtering messages, so we need to return false.
        End If

        Return False
    End Function
