We are trying to automate the click of the next button in the Lync interface. The problem is that we cannot click it securely. Sometimes it works; in other cases this is not so. What we are trying to do is open the Lync options window.
Here are some parts of the problem:
- we use the namespace
System.Windows.Automationto automate the user interface. - we usually call
AutomationElement.FindFirstto get the user interface element - this does not work for a button because there is no ancestor in the button menu
- so we use
TreeWalkerto move all descendantsAutomomationElement.RootElement - using
TreeWalker, we sometimes find a match, but weird and unpredictable sometimes we don’t - using Inspect.exe we see that there are no ancestors in the Context menu
How can we reliably find and press a button?
From inspect.exe
How found: Selected from tree...
