This part focuses on passing a presentation between PowerPointTemplate and PowerPointApplication in order to take advantage of the full range of features available with PowerPointWriter.
Adding to the Template
1. Add a new slide to the template from Part 2. This slide will be an optional extra slide that will not be included in the final presentation. For example, Our template file contains a slide with a disclaimer that is not necessary for the presentationcould be removed if necessary, for instance if the presentation was a draft. In this example, we will show you how to remove an optional slide.
The extra slide in the template file look like the following:
...
In order to delete this slide we will be using PowerPointApplication's Delete method. However, we have so far been working only in PowerPointTemplate. In order to take advantage of the methods in PowerPointApplication, we must first pass the completed template file to PowerPointApplication. This will be done in the code Writing the Code section of this tutorial. See Passing between Template and Application for more information.
