Retrieves the ancestor element nearest to the specified Microsoft UI Automation element in the tree view.
Type: IUIAutomationElement*
A pointer to the element from which to start the normalization.
Type: IUIAutomationElement**
Receives a pointer to the ancestor element nearest to the specified element in the tree view.
Type: HRESULT
If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
The element is normalized by navigating up the ancestor chain in the tree until an element that satisfies the view condition (specified by a previous call to IUIAutomationTreeWalker::Condition) is reached. But first, the passed element is tested to see if it matches a normalization condition. If so, the passed element is returned, even though it is not an ancestor.
The method returns UIA_E_ELEMENTNOTAVAILABLE if no matching element has been found.
This method is useful for applications that obtain references to UI Automation elements by hit-testing. The application might want to work only with specific types of elements, and can use IUIAutomationTreeWalker::Normalize to make sure that no matter what element is initially retrieved (for example, when a scroll bar gets the input focus), only the element of interest (such as a content element) is ultimately retrieved.
