■ 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"],
