IDataSource.Add()

Description:

The Add method adds a contact or contact group to a contacts database. If the contact or contact group already exists in the database, it is replaced with the new entry. You can thus use this method to both add and edit contacts and contact groups. The information is added to the specified database or, if no database is specified, to the default one. If the default database does not exist, it is created.

This method can be called both synchronously and asynchronously.

Syntax:

For synchronous calls:

result = so.IDataSource.Add(criteria);

For asynchronous calls:

result = so.IDataSource.Add(criteria, callback);

Arguments:

  • criteria:

    This is an object that specifies what contact information to add or edit and for which database. For more information about the object properties and how to define them, see section Criteria for adding and editing contact information.

  • callback:

    The callback argument is the name of the method that is executed when an asynchronous Add call has results or status information to return. You must define this method separately. Follow the instructions in section Defining the callback handler for an asynchronous method to define the callback method.

    This argument is used only with an asynchronous Add call.

Return value:

If synchronous, the Add method returns an object that contains an error code and an error message.

If asynchronous, the method returns an object that contains a transaction ID for the callback instance, an error code, and an error message. When the asynchronous call has completed, callback returns an object that contains an error code and an error message (see Table: Callback return value).

Property

Description

Value

result.TransactionID

This is a number used as an identification to match transactions started with an asynchronous Add call to one or more calls it generates to callback.

This property is only valid for asynchronous calls.

 

result.ErrorCode

This is a number that specifies a predefined error code.

See Service API error codes.

result.ErrorMessage

This is a text string that describes the error.

See Contacts Service API error messages.

Remarks:

  • The default contacts database is cntdb://c:contacts.cdb. The SIM card database is sim://global_adn.

  • If a contact or contact group is added with its id property specified, and the database already contains an entry with that id, the existing entry is replaced by the new one. If the id is not specified, a new entry is added to the database.
