Using UIAutomation - GetCachedParent

Question

Hi guys.

I am using the IUIAutomation library (COM version) via C#, to analyze Microsoft-Word UI structure.

No matter what I try, I am unable to perform a cache request that has a GetCachedParent which does not return null.

here is a small standalone sample:

private void TestFunc()
        {
            CUIAutomationClass Core = new CUIAutomationClass();
            var mainWindowElement = Core.ElementFromHandle(Process.GetProcessesByName("WINWORD").First().MainWindowHandle);
            var request = Core.CreateCacheRequest();
            request.AddProperty(UIA_PropertyIds.UIA_NamePropertyId);
            request.TreeScope = TreeScope.TreeScope_Subtree;
            var allTreeElements = mainWindowElement.FindAllBuildCache(TreeScope.TreeScope_Subtree, Core.RawViewCondition, request);
            var foundCachedParent = false;
            for (int i = 0; i < allTreeElements.Length; i++)
            {
                foundCachedParent = foundCachedParent || allTreeElements.GetElement(i).GetCachedParent() != null;
            }
            MessageBox.Show("Any parents? " + foundCachedParent);
        }

what am I missing? 

I have tried various TreeScope alternatives, to not avail.

thanks,

Eran

Hi Eran Broder,

Thank you for posting here.

I note that you are using 'UIAComWrapper' nuget package for which we don't provide help, and you can consider posting your question in the related forum for more efficient responses.

Thank you for your understanding.
