Powerpoint: how to insert document property (aka 'field') in slide?
While Word can do this, PowerPoint can't. AFAIK, you can have document properties in PPT, but you cannot insert them on a slide. The only updating field available for PowerPoint is the date and slide number. Anyway, there could be some workaround in VBA to achieve this. You can ask this on Stackoverflow to take your chance.
Just wrote a subroutine to put named properties into tagged text objects on all slides.
To put a file property onto slide(s). Create a textbox to hold the string. In the properties/Alt Text put the property name into square brackets.
Then execute the macro updateProperties()
.
i.e. [title]
- would allow the document title to be updated on multiple
Two special tags have been written:
[copyright]
would insert a copyright string, i.e. © 1998-2013 P.Boothroyd, NIS Oskemen[page]
would insert the slide number from the editor tab' Copy document properties into all slides ' (c) 2013, P.Boothroyd for NIS Oskemen Dim processPage As Slide Sub updateProperties() Dim page As Slide Dim propname As String ' parse all slides in the active presentation (document) For Each processPage In Application.ActivePresentation.Slides ' scan all elements of page for textbox with tagged "altText/title" field with "[" For Each obj In processPage.Shapes If Left(obj.Title, 1) = "[" Then Dim sStart, sEnd As Integer ' extract property from between square brackets sStart = 2 sEnd = InStr(2, obj.Title, "]") propname = Trim(Mid(obj.Title, sStart, sEnd - 2)) If obj.Type = msoTextBox Then ' set the text box to the requested value obj.TextFrame.TextRange.Text = getProperty(propname, obj.TextFrame.TextRange.Text) End If End If Next ' obj Next ' page End Sub ' get the named document property (with optional default) Function getProperty(propname, Optional def As String) As String ' property assigned the default value getProperty = def Dim found As Boolean found = False propname = LCase(propname) ' copyright is a generated property If propname = "copyright" Then Dim author As String Dim company As String Dim yearFrom As String Dim yearTo As String ' get all appropriate variables author = getProperty("author", "") company = getProperty("company", "") yearFrom = getProperty("created", "") yearTo = Format(Now(), "YYYY") ' insert copyright symbol getProperty = Chr(169) + " " ' attach year span for copyright notice If yearFrom yearTo Then getProperty = getProperty + yearFrom + "-" End If getProperty = getProperty + yearTo ' add the author getProperty = getProperty + " " + author ' add separator for author/company if both exist If Len(author) > 0 And Len(company) > 0 Then getProperty = getProperty & ", " End If getProperty = getProperty & company ' processed, so return the value found = True End If ' insert the slide number into the document If propname = "page" Then getProperty = processPage.SlideNumber found = True End If ' if generated name created return the value If found Then GoTo ret ' scan for standard MS (file) properties of the named value For Each p In Application.ActivePresentation.BuiltInDocumentProperties If LCase(p.Name) = propname Then getProperty = p.Value found = True Exit For End If Next ' p ' scan for customised properties of the named value If found Then GoTo ret For Each p In Application.ActivePresentation.CustomDocumentProperties If LCase(p.Name) = propname Then getProperty = p.Value found = True Exit For End If Next ' p ret: End Function
