Then I changed the PollrateOveride to 250ms. Save and Rebuild it. Then run my app again, did not see data send to SQL server.
I look around and saw that Datasubscriber1 icon no longer there, it dissappeared.
I repeat the process with my backup copy. Again Datasubscriber1 icon dissappeared.
This sounds like it might be one of the quirks of the Visual Studio designer. After the DataSubscriber disappears, try this:
- In Solution Explorer, select the AdvancedHMI project
- At the top of Solution Explorer click the Show All Files icon
- Expand down the form with the DataSubscriber
- You should now see a file with designer.vb on the end of the name
- Right click that file and select View Code
- Scroll down through that code and see if you still see the DataSubscriber referenced that disappeared from the form
