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
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.
Option Explicit
Public Function RenameSlide(oldName As String, newName As String)
' RenameSlide finds slide oldName and renames it to newName.
' Arguements:
' oldName: current (old) name of existing slide
' newName: new name for slide.
'
Dim tempBool As Boolean
Dim sld As Slide
Dim RetVal(0 To 1) As String
' Check if oldName can be found.
If SlideExists(oldName) Then
Set sld = Application.ActivePresentation.Slides(oldName)
Else
RetVal(0) = 1 'Error 1
RetVal(1) = "Error 1: slide with name " & oldName & " not found. Aborting."
Exit Function
End If
' Check if this slide name newName already exists.
If SlideExists(newName) Then
RetVal(0) = 2 'Error 1
RetVal(1) = "Error 2: slide with name " & newName & " already exists. Aborting."
Exit Function
End If
' Rename the slide
'Application.ActivePresentation.Slides(oldName) = newName
Application.ActivePresentation.Slides(oldName).Select
Application.ActiveWindow.View.Slide.Name = newName 'current slide
RetVal(0) = 0 'Success
RetVal(1) = "Success: slide renamed from '" & oldName & "' to '" & newName & "'."
End Function
Public Sub SetSlideName()
' Prompt user for new name for active slide.
'
Dim oldName As String
Dim newName As String
Dim sld As Slide
Dim msg As String
' Get current name of active slide.
oldName = Application.ActiveWindow.View.Slide.Name
msg = "Enter the new name for slide '" + oldName + "'."
retry:
newName = ""
' Prompt for new slide name. Loop until a name of at least 1 character is provided.
Do While newName = ""
newName = InputBox(msg, "Rename slide")
newName = Trim(newName)
If Len(newName) = 0 Then
msg = "Try again. You must enter a slide name to continue."
ElseIf newName = oldName Or newName = Str(vbCancel) Then
Exit Sub
End If
Loop
' If an existing slide already has name newName, then
' go back and prompt user again.slide name already exists
If SlideExists(newName) Then
msg = "Slide with this name already exists!"
GoTo retry
End If
' Set the new slide name
Application.ActiveWindow.View.Slide.Name = newName
MsgBox "Slide renamed to '" + newName + "'."
End Sub
Public Function SlideExists(SlideName As String) As Boolean
Dim RetVal As Boolean
Dim sld
' Assume slide does not exist.
SlideExists = False
' Try to find slide by name.
' If we error out, the slide does NOT exist.
On Error GoTo NoSlide
Set sld = ActivePresentation.Slides(SlideName)
' If we got this far, the slide DOES exist.
SlideExists = True
Exit Function
NoSlide:
' Error setting slide objects shows
' that slides does NOT exist.
SlideExists = False
End Function
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.
