Adding a Slide to a Presentation
 
Sub add()
    Dim mySlide As Slide
    Set mySlide = ActivePresentation.Slides.Add(Index:=1, _
        Layout:=ppLayoutTitle)
End Sub
   
Closing a Presentation
 
Sub close()
    ActivePresentation.Close
End Sub
   
To avoid the user being prompted, set the Saved property of the Presentation object to True before using the Close method-for example:
 
Sub save()
    With Presentations("Your PPT.ppt")
        .Saved = True
        .Close
    End With
End Sub
