Hinweise

Wenn Sie eine Instanz der PrintPreviewControl-Klasse erstellen, werden einige Lese-/Schreibeigenschaften auf die Anfangswerte festgelegt. Eine Liste dieser Werte finden Sie unter dem PrintPreviewControl-Konstruktor.

Beispiel

Im folgenden Codebeispiel werden die Document-Eigenschaft, die UseAntiAlias-Eigenschaft und die Zoom-Eigenschaft des PrintPreviewControl veranschaulicht. Zum Ausführen dieses Beispiels fügen Sie folgenden Code in ein Formular ein, und rufen Sie die InitializePrintPreviewControl-Methode im Konstruktor oder in der Load-Ereignisbehandlungsmethode des Formulars auf.
