Number PowerPoint Omit Hidden Slides

If you hide a number of slides you may want to number the slides so that the hidden slides are not numbered.

This vba does that keeping the numbers sequential. Note that the layouts MUST have a slide number placeholder (they normally will). The Function finds the Slide Number shape and the main sub routine numbers it sequentially.

Sub Number_NonHidden()
'For v.2007 onwards only
Dim osld As Slide
Dim objSN As Shape
Dim lngNum As Long
'check all slides
For Each osld In ActivePresentation.Slides
'Is it hidden
If osld.SlideShowTransition.Hidden Then
osld.HeadersFooters.SlideNumber.Visible = False
Else
osld.HeadersFooters.SlideNumber.Visible = True
Set objSN = getNumber(osld)
lngNum = lngNum + 1
If Not objSN Is Nothing Then ' there is a number placeholder
objSN.TextFrame.TextRange = CStr(lngNum + 1)
End If
End If
Next osld
End Sub

Function getNumber(thisSlide As Slide) As Shape
For Each getNumber In thisSlide.Shapes
If getNumber.Type = msoPlaceholder Then
If getNumber.PlaceholderFormat.Type = ppPlaceholderSlideNumber Then
'it's the slide number
Exit Function
End If
End If
Next getNumber
End Function
