Remarks
Data adapter objects provide different properties and methods that retrieve and submit data to external data sources; the data adapter that is associated with a form is dependent on the type of data source that was used when the form was initially created.
The QueryAdapter property allows you to access an InfoPath form's primary data source. To access the data adapter objects used for a form's secondary data sources, use the DataObjects property.
