Comentarios

Si ShowCheckBox es true, CheckBoxRegistryMeansDoNotShowDialog es truey el valor del Registro existe y contiene un valor distinto de cero, el cuadro de mensaje de excepción no se muestra y ExceptionMessageBox devuelve DefaultDialogResult cuando Show se llama a .

Esta propiedad suele ser true cuando el texto de la casilla de verificación es "No volver a mostrar este mensaje" o un mensaje similar.
