Support Questions / Re: Creating a separate thread to constantly read/Compute values?

« on: December 17, 2014, 02:37:08 PM »

Hi Archie,


I was going with this:

Code: [Select]


    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
            Control.CheckForIllegalCrossThreadCalls = False             'Eliminates some errors when multithreading
           Backgrounder = New Thread(AddressOf Me.BoxUPdate)           'Declaires Backgrounder as a new thread subroutine
          Backgrounder.Start()
    End Sub

with Backgrounder literally just reading and sleeping. But, this made something angry.

SO i will give your suggestion a shot.

Support Questions / Creating a separate thread to constantly read/Compute values?

« on: December 17, 2014, 10:51:53 AM »

Hi guys.

First off, being a long time FactoryTalk developer, advanceHMI is FANTASTIC. it is now my go-to solution when i need something that FT cannot provide.

Such as my current project, opening an excel file, reading data out of a user selectable table, and dumping it into a PLC. I got this to work perfectly, but I'm a bit stuck on creating another thread to continuously update to my program. I'm talking using the  EthernetIPforCLXCom1.Read constantly at a set interval.

Reason being is Id like to check the progress of a process and compare it to recipe data, then throw up a popup when complete. This, and populate the standard windows progress bar control.

I had something working for a bit, but it seemed to crash and/or blast the network. Any insight guys?

Thanks in advance!
