Built-in Applications and System Data

Dates

[StringToDate("6/1/95 12:00am"),

StringToDate ("6/30/95 11:59pm")],

nil,
nil);

To find the unique meeting in the month of June with the word "lunch" in the
title or the notes, and handle the possibility of an exception being thrown if this
criterion is not unique:

try

GetRoot().calendar:FindExactlyOneAppointment

(nil,
'["lunch"],
[StringToDate("6/1/95 12:00am"),
StringToDate("6/30/95 11:59pm")],
nil);

onexception |evt.ex| do

if CurrentException().data.errorCode = -48418

then //handle this case
else Rethrow()

The Dates application also provides a method,

FindNextMeeting

, which returns

an array with the meeting start date and duration, for the first meeting after a
specified time. The

FindNextMeeting

method is thus particularly useful for

finding an open time slot in the user's schedule.

Here is an example, which finds the next meeting after 2

P.M.

on November 1, 1996:

GetRoot().calendar:FindNextMeeting

(StringToDate("11/1/96 2pm"));
