Hi I am adding Value and label in ring control by program. But when I close my application and start again at that time I lose that value and label. Is there anyway I can save dynamically also Thanks"
The common way to do that is to save your data in a ini file (there is a ini Instrument library for this) and when your program start, read this ini file and populate the ring via the the function InsertListItem().
You can call the function SavePanelState before exiting your application, and then call RecallPanelState when you start it back up. That should do the trick.
