IDataSource.Export()

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).

+ + + + + + + + + + + + + + + + + + + + + +

**Table:** Return value +properties for Export
+ Property +	+ Description +	+ Value +
+ `result.TransactionID` +	+ This is a number used as an identification to match transactions started +with an asynchronous `Export` 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.
+
SIM card databases only support name and number keys for +vCard.
