Oh, sorry. FileSummary is the only dislog you can display. HOWEVER, if you notice when you go File > Properties there are a bunch of other things. These are the BuiltInDocumentProperties. These are:
Title, Subject, Author, Keywords, Comments, Template, Last Author, Revision Number, Application Name, Last Print Date, Creation Date, Last Save Time, Total Editing Time, Number of Pages, Number of Words , Number of Characters, Security, Category, Format, Manager, Company, Number of Bytes, Number of Lines, Number of Paragraphs, Number of Slides, Number of Notes, Number of Hidden Slides, Number of Multimedia Clips.
NOTE: clearly there are properties that apply for some applications that do not apply for others. Calling one inappropriately will return an error.
You can access them with the DocumentProperties collection. You can also access CustomDocumentProperties - see the File > Properties dialog. Why you can not get a full dialog display.....who knows? Maybe there is a way that I am unaware of. However, you certainly can GET them. Look up BuiltInDocumentProperties in Help.
What I am saying is that if you want to, you can build your own dialog to get, and set, values that are displayed in File > Properties.
