Why do Instance numbers change on a control?

[ctyankeeinok]

I have a script that is automating installation of printer drivers. I have seen where the instance number very same "OK" button changes depending on other things happening on the PC. What is going on? I have been using ControlClick($title,$text,"[CLASS:Button,Instance:3]","Primary") , but found that at times the script does not run properly because now the instance number is different. What should I be using to identify the control? Just the ID like [iD: 3]?

You have to use whatever will remain consistent. What works varies by the GUI you are working with. Maybe the ControlID is consistent, maybe X/Y coordinates, maybe the control text (i.e. "&Next"), etc.

When controls are created or destroyed at runtime, then there are more or less of them so enumerating controls (what the instance derivative is) returns different numbers. This is why we give several ways of identifying controls.
