CalEventMBS.endDate as date

dim e as CalEventMBS
msgbox e.endDate.longdate+" "+e.endDate.longtime

The client is responsible for making sure they never attempt to save an event with a start date that occurs after the endDate, or an endDate that occurs before the startDate. Calling saveEvent: on an improperly configured event will fail.
(Read and Write property)

CalEventMBS.isAllDay as boolean

True for all day events.
(Read and Write property)

CalEventMBS.isDetached as boolean

These properties are only meaningful for CalEvents which are instances of a repeating event.

If this CalEvent is an instance of a repeating event, and an attribute of this CalEvent has been changed to from the default value generated by the repeating event, isDetached will return true. If the CalEvent is unchanged from its default state, or is not a repeating event, isDetached returns false.

CalEventMBS.location as string

dim c as new CalCalendarStoreMBS

// set the date range where we look for event
dim sd as new date(2016,6,7,0,0,0)

// look for an event on that date
dim a() as CalEventMBS = c.events(sd,ed, c.calendars)
dim e as CalEventMBS = a(1)

// show location
MsgBox e.location

// change it
e.location = "Hamburg"

// check again
MsgBox e.location

// Save
dim error as NSErrorMBS
dim ok as Boolean = c.saveEvent(e, c.CalSpanThisEvent, error)

if ok then
  MsgBox "OK"
elseif error <> nil then
  MsgBox error.LocalizedDescription
else
  MsgBox "Failed."
end if

CalEventMBS.occurrence as date

These properties are only meaningful for CalEvents which are instances of a repeating event.

Returns the occurrence date of a CalEvent. Since all instances of a repeating event have the same UID, we need another way to differentiate between those CalEvents. This method returns the NSDate on which this event was originally scheduled to occur. This value will remain the same even if the event has been detached and its start date has changed. For CalEvents not part of a repeating pattern, this method will return the same value as startDate.

CalEventMBS.recurrenceRule as CalRecurrenceRuleMBS

// create a recurrence event:

dim rend as CalRecurrenceEndMBS

ed.day=21

dim calendars() as CalCalendarMBS = c.calendars
e.Title="Example Title"
e.calendar=calendars(0) // pick first calendar
e.notes="Example Notes"
e.URL="http://www.monkeybreadsoftware.de"

  if error<>Nil then s=error.localizedDescription
  MsgBox "OK"+EndOfLine+s
else
  if error<>Nil then s=error.localizedDescription
  MsgBox "Failed"+EndOfLine+s

Set to nil to remove recurrence rule.

CalEventMBS.startDate as date

msgbox e.startDate.longdate+" "+e.startDate.longtime

The client is responsible for making sure they never attempt to save an event with a start date that occurs after the endDate, or an endDate that occurs before the startDate. Calling saveEvent: on an improperly configured event will fail.
