GglGetCalendar (Function)
In French: GglRécupèreAgenda
Retrieves a Google calendar and its events according to its title or identifier. This function is using the Google Calendar service.
Caution: the access to the Google Calendars changes from November 17, 2014
From November 17 2014, Google is only using the Google API version 3 (Google API version 2 is abandoned). This change of version has modified the exchange format of data used by the functions for accessing the Google Calendars.
An "OAuth 2.0" authentication is now required to access this service. This authentication mode requires:
  • the declaration of the application in the Google console. To use the Google Calendars, the application must use the "Calendar API" service.
  • the use of new properties in the gglConnection variable.
See the help about GglConnect for more details.
Caution: The gglCalendar, gglEvent and gglLocation variables are also modified. Some properties become obsolete with the Google API version 3: they must not be specified anymore.
// Connection
Cnt is gglConnection
...
IF GglConnect(Cnt) = False THEN
Error(ErrorInfo())
END

// Retrieve the calendar named "Work"
Calendar is gglCalendar = GglGetCalendar(Cnt, "Work")
// Read the calendar events
IF ErrorOccurred = False THEN
 Evt is gglEvent
 FOR EACH Evt OF Calendar
Trace(Evt..Title)
 END
END
Syntax
<Result> = GglGetCalendar(<Google Connection> [, <Title or Identifier> [, <Beginning of Events> [, <End of Events> [, <String to Find>]]]])
<Result>: gglCalendar variable
Name of gglCalendar variable.
<Google Connection>: gglConnection variable
Name of gglConnection variable to use. This connection was validated by GglConnect.
Versions 20 and later
Caution: the properties of the gglConnection variable must be revised for the OAuth 2.0 authentication.

<Title or Identifier>: Optional Unicode character string
Title or identifier of sought calendar. If this parameter corresponds to an empty string (""), the first available calendar is retrieved (by default).
<Beginning of Events>: Optional DateTime
Start date and time of events to retrieve.
If <Beginning of Events> and <End of Events> are not specified, only the future events are retrieved (events from today's date).
If only <Beginning of Events> is specified, all the events found after this date will be retrieved (the limit date defined by Google is 01/01/2031).
<End of Events>: Optional DateTime
End date and time of events to retrieve.
If <Beginning of Events> and <End of Events> are not specified, only the future events are retrieved (events from today's date).
If only <End of Events> is specified, all the events found before this date will be retrieved (the limit date defined by Google is 01/01/1970).
<String to Find>: Optional character string
Text to find in the calendar events. If this parameter is specified, only the events containing the specified text will be listed. The search is performed on the name and on the description of the calendar. This search is not case sensitive. This parameter corresponds to an empty string by default.
Remarks

Possible error cases:

  • The Internet connection is not valid.
  • The authentication was not performed properly.
  • The XML response of the server cannot be read.
  • The calendar was not found.
