SUMMARY

This article provides a sample Microsoft Visual Basic for Applications macro (Sub procedure) that inserts a media object into a slide show and then places the object. The object is placed in the center of the slide.

NOTE: This macro must be run from an on-screen slide show. You can create an action button to run the macro, or you can change the action settings of another AutoShape so that it runs the macro when you click on the AutoShape.
