A collection of PublishObject objects representing the set of complete or partial loaded presentations that are available for publishing to HTML.
Assembly: Microsoft.Office.Interop.PowerPoint (in Microsoft.Office.Interop.PowerPoint.dll)
You can specify the content and attributes of the published presentation by setting various properties of the PublishObject object. For example, the SourceType property defines the portion of a loaded presentation to be published. The RangeStart property and the RangeEnd property specify the range of slides to publish, and the SpeakerNotes property designates whether or not to publish the speaker's notes.
You cannot add to the collection.
