Adding a presentation template to the presentations collection (C#

[Lucy]

Hi I am coding using Visual C#.

I can add a Word 2007 document as a template to the documents collection
like this:

Word.Application w_app;
Word._Document odoc;

w_app = new Microsoft.Office.Interop.Word.Application();
odoc = w_app.Documents.Add(ref file, ref missing, ref
missing, ref objFalse);

I want to do the same for PowerPoint 2007. The Presentation.Add() method
does not add a presentation template. How can I do this?
