Remarques

Si ShowCheckBox c’est truele cas, CheckBoxRegistryMeansDoNotShowDialog est trueet que la valeur de Registre existe et contient une valeur non nulle, la boîte de message d’exception n’est pas affichée et ExceptionMessageBox retourne DefaultDialogResult quand Show elle est appelée.

Cette propriété est généralement true lorsque le texte de la case à cocher est « Ne plus afficher ce message » ou un message similaire.
