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

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(

,

,

,

,

)

. 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:
