Exempel

I följande exempel skickas ett rotelement till en funktion som returnerar en samling automationselement som är underordnade roten och uppfyller en uppsättning egenskapsvillkor. Det här exemplet hämtar de UI Automation element som stöder GridPattern men som för närvarande bara har ett objekt i trädet.
