// So in this sample, if TreeScope_Element is used as the scope here, (which is the
// default), then only properties for the found hyperlinks will be cached. The sample
// optionally caches the properties for the direct children of the hyperlinks too.
// This means that if we find a hyperlink with no name, we can search the hyperlink's
// children to see if one of the child elements has a name we can use. (Searching the

// (i) Retrieve a property later for an element which we didn't request should be in

//
// (ii) We can call a method of a pattern that the element supports. Eg if Full mode was
// not used here, we would not be able to call Invoke() on the hyperlink later.
// If we specified a Mode of None for the cache request here, then the results only include
// cached data, with no connection at all after the call returns to the source elements. If
// only data is required, then it would be preference to use a Mode of None, as less work is
// required by UIA. (Also, if a reference to the element is returned in the cache and kept
// around for a non-trivial time, then it increases the chances that the target process
// attempts to free the element, but it can't do so in a clean manner as it would like,
// due to the client app here holding a reference to it.) To specify that we want a Mode of
// None, we'd make this call here:
// cacheRequest.AutomationElementMode = AutomationElementMode.AutomationElementMode_None;

// Now regardless of whether we're using a cache, we need to specify which elements

// combine a number of properties with AND and OR logic.
// We shall first say that we're only interested in elements that exist in the Control view.
// By default, a property condition uses the Raw view, which means that every element in the
// target browser's UIA tree will be examined. The Control view is a subset of the Raw view,
// and only includes elements which present some useful UI. (The Raw view might include
// container elements which simply group elements logically together, but the containers

// same results here if we didn't include the Control view clause, (as hyperlinks
// won't exist only in the Raw view), but by specifying that we're only interested
// in the Control view, UIA won't bother checking all the elements that only exist
// in the Raw view to see if they're hyperlinks.
IUIAutomationCondition condition = _automation.CreateAndCondition(conditionControlView, conditionHyperlink);

// to control how far UIA will go in looking for elements to include in the search results. For
// this sample, we must check all descendants of the browser window.
// *** Note: use TreeScope_Descendants with care, as depending on what you're searching for, UIA may
// have to process potentially thousands of elements. For example, if you only need to find top level
// windows on your desktop, you would search for TreeScope_Children of the root of the UIA tree. (The
// root element can be found with a call to IUIAutomation::GetRootElement().)
// *** Note: If the following searches included searching for elements in the client app's own UI,
