IUIAutomationCacheRequest::get_AutomationElementMode method (uiautomationclient.h)

Article
02/22/2024

Indicates whether returned elements contain full references to the underlying UI, or only cached information.

This property is read/write.

Syntax

HRESULT get_AutomationElementMode(
  AutomationElementMode *mode
);

Parameters

mode

Return value

None

Remarks

AutomationElementMode_Full is the default value, and specifies that returned elements contain a full reference to the underlying UI. AutomationElementMode_None specifies that the returned elements have no reference to the underlying UI, and contain only cached information.

Certain operations on elements, including GetCurrentPropertyValue, and SetFocus, require a full reference; attempting to perform these on an element that has none results in an error.

Using AutomationElementMode_None can be more efficient when only properties are needed, as it avoids the overhead involved in setting up full references.
