Beispiele

Im folgenden Codebeispiel wird das Erstellen einer , das Hinzufügen von ImageListBildern zur Images Eigenschaft, das Festlegen der ImageSize Eigenschaft und die Verwendung der Draw Methode veranschaulicht. Wenn Sie dieses Beispiel ausführen möchten, platzieren Sie es in einem Formular, das eine Schaltfläche mit dem Namen enthält Button1. Im Beispiel wird davon ausgegangen, dass c:\Windows\vorhanden FeatherTexture.bmp ist.Gone Fishing.bmp Ändern Sie das Beispiel entsprechend, wenn die Bitmaps nicht auf Ihrem System vorhanden sind oder an einem anderen Speicherort vorhanden sind.
