IUIAutomationElement::FindAll method (uiautomationclient.h)
Returns all UI Automation elements that satisfy the specified condition.
HRESULT FindAll( TreeScope scope, [in] IUIAutomationCondition *condition, [out, retval] IUIAutomationElementArray **found );
A pointer to a condition that represents the criteria to match.
[out, retval] found
Receives a pointer to an array of matching elements. Returns an empty array if no matching element is found.
If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
The scope of the search is relative to the element on which the method is called. Elements are returned in the order in which they are encountered in the tree.
This function cannot search for ancestor elements in the Microsoft UI Automation tree; that is, TreeScope_Ancestors is not a valid value for the scope parameter.
When searching for top-level windows on the desktop, be sure to specify TreeScope_Children in the scope parameter, not TreeScope_Descendants. A search through the entire subtree of the desktop could iterate through thousands of items and lead to a stack overflow.
If your client application might try to find elements in its own user interface, you must make all UI Automation calls on a separate thread.
