Presentations Object (PowerPoint)
Published: July 16, 2012
A collection of all the Presentation objects in Microsoft PowerPoint. Each Presentation object represents a presentation that's currently open in PowerPoint.
The Presentations collection doesn't include open add-ins, which are a special kind of hidden presentation. You can, however, return a single open add-in if you know its file name. For example Presentations("oscar.ppa") will return the open add-in named "Oscar.ppa" as a Presentation object. However, it is recommended that the AddIns collection be used to return open add-ins.
If your Visual Studio solution includes the Microsoft.Office.Interop.PowerPoint reference, this collection maps to the following types:
Microsoft.Office.Interop.PowerPoint.Presentations.GetEnumerator (to enumerate the Presentation objects.)
Use the Presentations property to return the Presentations collection. Use the Add method to create a new presentation and add it to the collection. The following example creates a new presentation, adds a slide to the presentation, and then saves the presentation.
Use Presentations(index), where index is the presentation's name or index number, to return a single Presentation object. The following example prints presentation one.
Use the Open method to open a presentation and add it to the Presentations collection. The following example opens the file Sales.ppt as a read-only presentation.
