GglListContact (Function)

In french: GglListeContact

Retrieves the list of contacts associated with the specified Google account.

Caution: the access to the Google Contacts 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 Contacts.

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 Contacts, the application must use the "Contacts 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.

Example

// Connection
Cnt is gglConnection
...
// Retrieves all the contacts
arrContacts is array of 0 gglContact = GglListContact(Cnt)

// Example with 10 contacts per page:
// First page
// Retrieves all the contacts, with a maximum of 10 contacts, starting from index 1
arrContacts = GglListContact(Cnt, "", 1, 10)
// Second page
// Retrieves all the contacts, with a maximum of 10 contacts, starting from index 11
arrContacts = GglListContact(Cnt, "", 11, 10)
// Browse the contacts
MyContact is dynamic gglContact
FOR EACH MyContact OF arrContacts
Trace(MyContact..Name)
END
