Das folgende Codebeispiel veranschaulicht die Verwendung der MinSizeMember , MaxSizeund ShowEffects und FontMustExist sowie die Behandlung des Ereignisses Apply . Fügen Sie zum Ausführen dieses Beispiels den folgenden Code in ein Formular ein, das einen FontDialog benannten FontDialog1 und einen Button mit dem Namen Button1enthält.
