- In Solution Explorer, expand down the AdvancedHMIControl project
- Under AdvancedHMIControl, expand dowm the Controls folder
- Right click BasicLabel.vb and select View Code
- Modify the SubscribeToComDriver routine as show here:

Code: [Select]

    Private Sub SubscribeToComDriver()
        If Not DesignMode And IsHandleCreated Then
            '* Create a subscription handler object
            If SubScriptions Is Nothing Then
                SubScriptions = New SubscriptionHandler
                SubScriptions.Parent = Me
                AddHandler SubScriptions.DisplayError, AddressOf DisplaySubscribeError
            End If

            SubScriptions.ComComponent = m_ComComponent

            SubScriptions.SubscribeAutoProperties()
        End If
    End Sub
