Description:
The Export method exports a contact from a contacts
database. The information is exported to a vCard file.
This method can be called both synchronously and asynchronously.
Syntax:
For synchronous calls:
result = so.IDataSource.Export(criteria);
For asynchronous calls:
result = so.IDataSource.Export(criteria, callback);
Arguments:
criteria:
This is an object that specifies the contact to export and optionally the source database. For more information about the object properties and how to define them, see section Criteria for exporting a contact.
callback:
The callback argument is the name of the method
that is executed when an asynchronous Export 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 Export call.
Return value:
If synchronous, the Export 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).
