The CDO Message COM class is a concrete implementation of the following interfaces:
The Message COM class is also of CoType TRow. CoType TRow interfaces are defined as part of the OLE DB specification:
C++ programmers can use this family of interfaces for raw access to the data that makes up the message the same way they can using the OLE DB data access layer directly.
Instances of the Message COM class can be created directly, and are used to create or manage complete messages. Instances of this class are essentially polymorphic, acting as a generic body part (IBodyPart interface), as the complete message (IMessage interface), and as an object of CoType TRow (OLE DB TRow interfaces).
The IDataSource interface is provided to handle routine transfer of message data in and out of other objects, such as BodyPart and Microsoft® Active X® Data Objects (ADO) Stream objects.
