This example creates a duplicate of slide one in the active presentation and then sets the background shading and the title text of the new slide. The new slide will be slide two in the presentation.
Set newSlide = ActivePresentation.Slides(1).Duplicate
With newSlide
.Background.Fill.PresetGradient msoGradientVertical, _
1, msoGradientGold
.Shapes.Title.TextFrame.TextRange _
.Text = "Second Quarter Earnings"
End With
This example adds a new, blank slide at the end of the active presentation, adds a diamond shape to the new slide, duplicates the diamond, and then sets properties for the duplicate. The first diamond will have the default fill color for the active color scheme; the second diamond will be offset from the first one and will have the default shadow color.
Set mySlides = ActivePresentation.Slides
Set newSlide = mySlides.Add(mySlides.Count + 1, ppLayoutBlank)
Set firstObj = newSlide.Shapes _
.AddShape(msoShapeDiamond, 10, 10, 250, 350)
With firstObj.Duplicate
.Left = 150
.Fill.ForeColor.SchemeColor = ppShadow
End With
