The Encoder exposes a COM IDispatch interface that enables a client application to call methods and properties.
This SDK focuses on client applications written in Microsoft® Visual Basic®. For detailed information on using Microsoft Visual C++® to create an Automation client application, see the Automation Programmer's Reference from Microsoft Press (ISBN 1-57231-584-9). Visual Basic is recommended for most applications because it hides the details of connecting to the IDispatch and other COM interfaces.
