Context: A PowerPoint slide in C# has a property Slide.Name (usually contains an arbitrary string value). In my C# application I would like to use this property to identify slides (the slide order is to unreliable).
Question: How can I manually set the Slide.Name property in the PowerPoint Application?
My problem is very like to the: “How to name an object within a PowerPoint slide?” but just on the slide level.
Any help would be appreciated.
There is no built-in functionality in PowerPoint that allows you to edit the name of a slide. As Steve mentioned, you have to do it using VBA code. The slide name will never change due to inserting more slides, and it will stay the same even if you close PowerPoint; the slide name set in VBA code is persistent. Here's some code I wrote to allow you to easily view the name of the currently selected slide and allow you to rename it:
'------------------------------------------------------------------
' NameSlide()
'
' Renames the current slide so you can refer to this slide in
' VBA by name. This is not used as part of the application;
' it is for maintenance and for use only by developers of
' the PowerPoint presentation.
'
' 1. In Normal view, click on the slide you wish to rename
' 2. ALT+F11 to VB Editor
' 3. F5 to run this subroutine
'------------------------------------------------------------------
Sub NameSlide()
Dim curName As String
curName = Application.ActiveWindow.View.Slide.name
Dim newName As String
retry:
newName = InputBox("Enter the new name for slide '" + curName + "', or press Cancel to keep existing name.", "Rename slide")
If Trim(newName) = "" Then Exit Sub
Dim s As Slide
' check if this slide name already exists
On Error GoTo SlideNotFound
Set s = ActivePresentation.Slides(newName)
On Error GoTo 0
MsgBox "Slide with this name already exists!"
GoTo retry
Exit Sub
SlideNotFound:
On Error GoTo 0
Application.ActiveWindow.View.Slide.name = newName
MsgBox "Slide renamed to '" + newName + "'."
End Sub
You can't manually set the slide name, but with a bit of code, it's simple. In VBA, for example:
Sub NameThatSlide()
ActivePresentation.Slides(1).Name = "Whatever You Like Here"
End Sub
I'm not certain that this will enable you to set the Slide.Name property because I'm not a VBA programmer, but anyway AFAIK the easiest way to name slides in PowerPoint 2010 is using Outline view.
If you position your mouse farthest left on a created slide, you can drag rightwards a kind of vertical slide sorter. At the top of that pane, you'll see two tabs: Slides and Outline.
Select Outline, you'll see each slide numbered and a grey grab button which allows you to reorder your slides. If you click to the right of that, you can type in whatever name you like, say Home.
In the main view pane, the slide will then have Home emblazoned across it. You can then either leave it there, or conceal it by altering the font colour to the background or by moving the text outside the presentation frame.
BTW You can use these names in hyperlinks.
used the Sub SplitFile() function to create individual slides from a deck of >100 slides. All went well!! But can anyone tell me what code do I use to rename the file automatically, assuming that each slide has a title in a text box? I want the slide title to be the file name for the new, individual slide created.
Here's the code I used to create individual slides (as individual files), thanks to whoever posted it online.
Sub SplitFile() Dim lSlidesPerFile As Long Dim lTotalSlides As Long Dim oSourcePres As Presentation Dim otargetPres As Presentation Dim sFolder As String Dim sExt As String Dim sBaseName As String Dim lCounter As Long Dim lPresentationsCount As Long ' how many will we split it into Dim x As Long Dim lWindowStart As Long Dim lWindowEnd As Long Dim sSplitPresName As String
On Error GoTo ErrorHandler
Set oSourcePres = ActivePresentation
If Not oSourcePres.Saved Then
MsgBox "Please save your presentation then try again"
Exit Sub
End If
lSlidesPerFile = CLng(InputBox("How many slides per file?", "Split Presentation"))
lTotalSlides = oSourcePres.Slides.Count
sFolder = ActivePresentation.Path & "\"
sExt = Mid$(ActivePresentation.Name, InStr(ActivePresentation.Name, ".") + 1)
sBaseName = Mid$(ActivePresentation.Name, 1, InStr(ActivePresentation.Name, ".") - 1)
If (lTotalSlides / lSlidesPerFile) - (lTotalSlides \ lSlidesPerFile) > 0 Then
lPresentationsCount = lTotalSlides \ lSlidesPerFile + 1
Else
lPresentationsCount = lTotalSlides \ lSlidesPerFile
End If
If Not lTotalSlides > lSlidesPerFile Then
MsgBox "There are fewer than " & CStr(lSlidesPerFile) & " slides in this presentation."
Exit Sub
End If
For lCounter = 1 To lPresentationsCount
' which slides will we leave in the presentation?
lWindowEnd = lSlidesPerFile * lCounter
If lWindowEnd > oSourcePres.Slides.Count Then
' odd number of leftover slides in last presentation
lWindowEnd = oSourcePres.Slides.Count
lWindowStart = ((oSourcePres.Slides.Count \ lSlidesPerFile) * lSlidesPerFile) + 1
Else
lWindowStart = lWindowEnd - lSlidesPerFile + 1
End If
' Make a copy of the presentation and open it
For Each oSlide In ActiveWindow.Presentation.Slides
strTitles = strTitles _
& "Slide: " _
& CStr(oSlide.SlideIndex) & vbCrLf _
& oSlide.Shapes.Title.TextFrame.TextRange.Text _
& vbCrLf & vbCrLf
Next oSlide On Error GoTo ErrorHandler
intFileNum = FreeFile
sSplitPresName = sFolder & sBaseName & _ "_" & CStr(lWindowStart) & "-" & CStr(lWindowEnd) & "." & sExt oSourcePres.SaveCopyAs sSplitPresName, ppSaveAsDefault Set otargetPres = Presentations.Open(sSplitPresName, , , True)
With otargetPres
For x = .Slides.Count To lWindowEnd + 1 Step -1
.Slides(x).Delete
Next
For x = lWindowStart - 1 To 1 Step -1
.Slides(x).Delete
Next

You can rename a slide manually or with VBA. Once you know how, the door opens to some interesting possibilities, which I will demonstrate with code below.
Manually renaming slides. This ability is hidden in the VBA Editor's Properties pane, but it does not require coding.
If the Developer ribbon is not visible, enable it: File > Options > Customize Ribbon > check the Developer Main Tab.
From the Developer ribbon, click the Visual Basic menu item to open the Visual Basic Editor.
Press the Ctrl+R keys to navigate to the Project Explorer pane.
Expand "Microsoft PowerPoint Objects"
Click on any slide to select it.
Press the F4 key to navigate to the Properties pane.
Edit the (Name) item, and press Enter to apply the name change.
The slide name change may not appear immediately in the VBA Project Explorer pane. As long as the name is correct in the Properties pane, the name changed successfully.
This VBA code will also do the trick (hide slide number 1):
ActivePresentation.Slides(1).SlideShowTransition.Hidden = msoTrue
This code block covers a few ways to manage slide names and answers the main question.

' Assume slide does not exist.

As an aside, I use the slide naming trick and a little VBA to selectively remove certain slides from printing. I added a few extra VBA macros for the sake of populating the Macros list. From any slide: Developer ribbon > Macros > Select Macro > Run button. Use this method to kick off my PresentSlide, DontPresentSlide, PrintSlide and DontPrintSlide macros. Once you have properly tagged your various slides, simply run the PrepToPresentSlides or PrepToPrintSlides macro before you present or print, respectively.
Play around with these macros a bit and read the comments. You will find that I wrote the code extensibly, so you can modify it easily for your needs.
The code below helps me to manage which slides and objects are printed and which are presented on-screen. This is particularly useful when I want to print reference slides but not cover them. It is even more useful when I have slides with animations. Animations don't usually translate print well. So, I choose not to print some animated objects at all. In fact, I can even add in substitute content for the objects to be used just for printing (hidden when presenting) - though I rarely do this. Instead, I will typically hide the animation from printing or create a slide to present and a non-animated copy of it for print. With these macros, it is easy to manage a mix and match of slides and objects for print and slides and objects for presentation. I hope you enjoy.
