Der Kontextknoten für dieses ContextNode-Objekt.

Beispiele

Im folgenden Beispiel wird gezeigt, wie die Type-Eigenschaft eines ContextNode-Objekts mit dem Namen selectedNode verwendet wird. Der Text von einem TextBox, selectedResultsTextBox, wird anders aufgefüllt, was vom Knotentypen abhängt. In den meisten Fällen wird die erkannte Zeichenfolge verwendet, jedoch wird für InkWord die erkannte Zeichenfolge der Zeile verwendet und das Wort wird in der TextBox ausgewählt.
