De UI Automation runtime-id van het venster waarop de gebeurtenis is gegenereerd.

Voorbeelden

In het volgende voorbeeld controleert de handler voor de gesloten venstergebeurtenis of de runtime-id van het gesloten venster in een lijst staat met de id's van geopende vensters. Als de runtime-id aanwezig is, wordt deze verwijderd uit de lijst.

Opmerkingen

Wanneer uw toepassing een gesloten venstergebeurtenis ontvangt, kan de parameter sender van de gebeurtenis-handler niet worden gebruikt om informatie te verkrijgen over het venster dat is gesloten, omdat het bijbehorende Microsoft UI Automation element niet meer geldig is. Gebruik GetRuntimeId dit om het venster te vergelijken met een bekende id.
