Version and Description

Besides the ProgID and the CLSID you might want to add other two fields to the

<Registration>

tag. These are Version
and Description
and are both strings. The number version is usually a string of the form:

n.nn

The version string is also appended to the ProgID for those applications that require the creation of a version-dependent instance of the object. The description text—as well as all this data—will be stored in the registry and made available to those development tools that requires a description for the COM objects in use.
