A bitwise combination of values that specifies the scope of the search.


The object containing the criteria to match.

Return Value

The first element that satisfies the condition, or a null reference (Nothing in Visual Basic) if no match is found.

The scope of the search is relative to the element on which the method is called.

When searching for a top-level window on the desktop, be sure to specify Children in scope, not 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.

The following example shows how to find a child window from its identifier.
