■ To delete a single instance of the repeating event created in “Adding Meetings

or Events”:

GetRoot().calendar:DeleteEvent ("George's birthday",

StringToDate("2/22/95"), true);

■ To delete the whole series of George’s birthdays by passing in a meeting frame

for a repeating meeting:

GetRoot().calendar:DeleteEvent

( GetRoot().calendar:FindAppointment

("George's birthday",

nil,

StringToDate("2/22/95"),

'RepeatingEvent,

nil)

[0], //FindAppointment returns an array

nil, // again, these two params. are ignored

nil);

■ The preferred way to delete the repeating event series is by calling

DeleteRepeatingEntry:

GetRoot().calendar:DeleteRepeatingEntry

("George's birthday", StringToDate("2/22/95"), true);

Finding Meetings or Events 19

The Dates application provides two methods to ﬁnd meetings or events in one of

the Dates soups:

FindAppointment and FindExactlyOneAppointment.

The

FindAppointment method takes the following parameters:

FindAppointment(mtgText, findWords, dateRange, type,

maxNumberToFind). The FindExactlyOneAppointment method shares the

same ﬁrst four parameters, but (not surprisingly) does not use a

maxNumberToFind

parameter. The

FindExactlyOneAppointment method functions exactly like

FindAppointment, except that if more than one meeting or event fits the search

criteria, an exception (error –48418) is thrown.

The following examples show how to find meetings with these two methods:

■ To ﬁnd all meetings in the month of June 1995 with the word “lunch” in the title

or the notes:

GetRoot().calendar:FindAppointment

(nil,

'["lunch"],
