The ATVEF enhancement component, ATVEFSnd.dll, contains four object classes that implement the ATVEF-related interfaces:
Your content server application will co-create one of the first three classes. The one you choose depends on how and where you are sending your data. All applications must also co-create an instance of CATVEFPackage to prepare enhancement files before they are sent to clients. The first three classes each implement their own initialization interface, but they all implement IATVEFAnnouncement to create announcements and IATVEFSend to send announcements, triggers, and packages.
