Placeholders Property
Returns a Placeholders collection that represents the collection of all the placeholders on a slide. Each placeholder in the collection can contain text, a chart, a table, an organizational chart, or another object. Read-only.
Example
This example adds a slide to the active presentation and then adds text to both the title (which is the first placeholder on the slide) and the subtitle.
Set myDocument = ActivePresentation.Slides(1)
With ActivePresentation.Slides _
.Add(1, ppLayoutTitle).Shapes.Placeholders
.Item(1).TextFrame.TextRange.Text = "This is the title text"
.Item(2).TextFrame.TextRange.Text = "This is subtitle text"
End With
