Interleave slides from several presentations


A visitor to the PowerPoint Newsgroup asked whether it was possible to combine slides from several different presentations one at a time to end up with something like this:

Presentation 1, Slide 1
Presentation 2, Slide 2
Presentation 3, Slide 3

Presentation 1, Slide 1
Presentation 2, Slide 2
Presentation 3, Slide 3

and so on.


Here's a little bit of code that'll stitch the presentations together as requested.

It's hardly the most efficient thing in the world, as it opens and closes each presentation many times, but the logic's easier to follow that way and as long as it's the computers's fingers getting tired and not ours, why worry?

Sub InterLeaveMe()
' Assumes you start with a new presentation based on same template as
' "component" presentations, new presentation already open when you run the macro

    Dim oNewPres As Presentation
    Dim oSamplePres As Presentation
    Dim sPresBaseName As String
    Dim x As Long
    Dim y As Long
    Dim lNumPresentations As Long
    Dim lNumSlides As Long

    ' Edit these as needed
    sPresBaseName = "c:\temp\Pres"
    lNumPresentations = 3   ' number of presentations
    lNumSlides = 3          ' number of slides in each pres

    Set oNewPres = ActivePresentation

    For x = 1 To lNumSlides
        For y = 1 To lNumPresentations
            Set oSamplePres = Presentations.Open(sPresBaseName & CStr(y) & ".PPT")

End Sub
