IProgressNotify interface

Enables applications and other objects to receive notifications of changes in the progress of a downloading operation.

When to implement

You do not need to implement IProgressNotify. The downloading code implements this interface, and the asynchronous storage implementation provides a connection point for dispatching notifications to it. An application can also register an IProgressNotify sink to receive progress notifications for individual streams.

When to use

You do not need to call this interface. The compound files implementation uses IProgressNotify::OnProgress to control the blocking behavior of the asynchronous storage and to trigger additional byte range requests if applicable.
