SlideRange Interface

Office 2010

A collection that represents a notes page or a slide range, which is a set of slides that can contain as little as a single slide or as much as all the slides in a presentation.

You can include whichever slides you want — selected from all the slides in the presentation or from all the slides in the selection — to construct a slide range. For example, you could construct a SlideRange collection that contains the first three slides in a presentation, all the selected slides in the presentation, or all the title slides in the presentation.

Just as you can work with several slides at the same time in the user interface by selecting them and applying a command, you can work with several slides at the same time programmatically by constructing a SlideRange collection and applying properties or methods to it. And just as some commands in the user interface that work on single slides aren't valid when multiple slides are selected, some properties and methods that work on a Slide object or on a SlideRange collection that contains only one slide will fail if they are applied to a SlideRange collection that contains more than one slide. In general, if you can't do something manually when more than one slide is selected (such as return the individual shapes on one of the slides), you can't do it programmatically by using a SlideRange collection that contains more than one slide.

For those operations that work in the user interface whether you have a single slide or multiple slides selected (such as copying the selection to the Clipboard or setting the slide background fill), the associated properties and methods will work on a SlideRange collection that contains more than one slide. Here are some general guidelines for how these properties and methods behave when they're applied to multiple slides.

  • Applying a method to a SlideRange collection is equivalent to applying the method to all the Slide objects in that range as a group.

  • Setting the value of a property of the SlideRange collection is equivalent to setting the value of the property in each slide in that range individually (for a property that takes an enumerated type, setting the value to the "Mixed" value has no effect).

  • A property of the SlideRange collection that returns an enumerated type returns the value of the property for an individual slide in the collection if all slides in the collection have the same value for that property. If the slides in the collection don't all have the same value for the property, the property returns the "Mixed" value.

  • A property of the SlideRange collection that returns a simple data type returns the value of the property for an individual slide in the collection if all slides in the collection have the same value for that property. If the slides in the collection don't all have the same value for the property, the property will return – 2 or generate an error. For example, using the Name property on a SlideRange object that contains multiple slides will generate an error because each slide has a different value for its Name property.

  • Some formatting properties of slides aren't set by properties and methods that apply directly to the SlideRange collection, but by properties and methods that apply to an object contained in the SlideRange collection, such as the ColorScheme object. If the contained object represents operations that can be performed on multiple objects in the user interface, you will be able to return the object from a SlideRange collection that contains more than one slide, and its properties and methods will follow the preceding rules. For example, you can use the ColorScheme property to return the ColorScheme object that represents the color schemes used on all the slides in the specified SlideRange collection. Setting properties for this ColorScheme object will also set these properties for the ColorScheme objects on all the individual slides in the SlideRange collection.

The following examples describe how to:

  • Return a set of slides that you specify by name or index number

  • Return all or some of the selected slides in a presentation

  • Return a notes page

  • Apply properties and methods to a slide range
