Title: Using PLCAddressVisible with FormChangeButton
Post by: scott.clark on October 30, 2015, 07:35:41 PM

Using AdvancedHMI 3.99a

I am having an issue hiding the a FormChangeButton using the PLCAddressVisible property.

I have a Bool type variable in the PLCAddressVisible property and have selected the CommComponent EthernetIPforCLXCom1. but the state of the PLCAddress has no effect. 

I know the PLC address I am using is good, tested it with the PLCAddressVisible property for a BasicButton.  Any ideas?

I can't believe that slipped through so long without getting reported.

Add this code to FormChangeButton.vb

Code: [Select]

    Protected Overrides Sub OnHandleCreated(e As EventArgs)
        MyBase.OnHandleCreated(e)

        SubscribeToCommDriver()
    End Sub

Then make sure ComComponent property is set
