Those mask properties are used for that. Each is a flag of bits. You have to
interpret the bits of DayOfWeekMask, DayOfMonth, MonthOfYear.

Thanks for the help, I have managed to map the dayly and weekly options on
the recurrence pattern but I am not sure which properties store the
monthly
option. I know that frequency is stored in the interval property but do
you
know where the day and the week in the month (e.g. third week) are stored
?
