Question

How to add hyperlink to concrete slide inside presentation using c#?
For now I have found how to Hyperlink to a site:

TextRange.ActionSettings[Microsoft.Office.Interop.PowerPoint.PpMouseActivation.ppMouseClick].Hyperlink.Address = “http://www.google.com”;

and found options to Last/First/Next

TextFrame.TextRange.ActionSettings[PpMouseActivation.ppMouseClick].Action = PpActionType.ppActionFirstSlide;

but not to slide4

Answer 1

If you add the setting manually in PowerPoint then ask it what the setting is, it’ll tell you. For example, add a link to Slide 4 to a text box, make sure the text box is selected and run this:

Sub Thing()
    Dim oSh As Shape
    Set oSh = ActiveWindow.Selection.ShapeRange(1)
    With oSh
        Debug.Print .ActionSettings(1).Hyperlink.Address
        Debug.Print .ActionSettings(1).Hyperlink.SubAddress
    End With
End Sub

The result, a blank line (no hyperlink address) and a subaddress of:

259,4,Title of slide 4

259 is the SlideID
4 is the SlideIndex
“Title of slide 4” is the title text on slide 4

I’m fairly sure the ID and Index are necessary; the title is not. For example to set a link to slide 3 in the same presentation:

Sub ThingTwo()
    Dim oSh As Shape
    Set oSh = ActiveWindow.Selection.ShapeRange(1)
    With oSh
        .ActionSettings(1).Hyperlink.Address = ""
        .ActionSettings(1).Hyperlink.SubAddress = "258,3,"
    End With
End Sub

Doing it in c# … left as an exercise for the reader.
