Powerpoint 2010 - VBA or .NET - Correct handler on slide display

Question

Hi

SlideShowNextSlideEventHandler or SlideShowNextBuildEventHandler ?

=> Which is the one i want to be able to refresh images, excel chart links or web page references before the slide is displayed ? (no minimise flicker, and make the transition between slides as soon as possible)

If SlideShowNextBuildEventHandler i am still at a road block as per post  http://social.msdn.microsoft.com/Forums/en-US/officegeneral/thread/ecdd0b52-135d-4f8f-a0cd-ebdc9cb8168a 

 Thanks

Hi Greg,

Thanks for posting in the MSDN Forum.

"Which is the one i want to be able to refresh images, excel chart links or web page references before the slide is displayed ? (no minimise flicker, and make the transition between slides as soon as possible)" I think I'm not very sure about your goal. I suppose you want to add some shape into the exists slides when it is going to be shown.

This snippet is developed under Visual Studio 2010, PowerPoint 2010. It will add a label at the left top to show slide index automatically.

Public Class ThisAddIn
    Private WithEvents PPApp As PowerPoint.Application

    Private Sub ThisAddIn_Startup() Handles Me.Startup
        PPApp = Application
    End Sub

    Private Sub ThisAddIn_Shutdown() Handles Me.Shutdown

    End Sub

    Private Sub PPApp_SlideShowNextSlide(ByVal Wn As  _
                                         PowerPoint.SlideShowWindow) _
                                     Handles PPApp.SlideShowNextSlide
        Dim slide As PowerPoint.Slide
        Dim shape As PowerPoint.Shape

        slide = Wn.View.Slide
        shape = slide.Shapes.AddLabel(Microsoft.Office.Core.MsoTextOrientation.msoTextOrientationHorizontal, 0, 0, 100, 100)
        shape.TextFrame.TextRange.Text = "This is page : " & CStr(slide.SlideIndex)
    End Sub

End Class

I hope it can help you.

Have a good day,

Tom

Thanks Tom

More info - i used the term refresh because that is what i mean, e.g. whether it is an linked image, or linked excel chart, i want to refresh the content on display (by default, Powerpoint only does this on startup).

If a presentation is in a loop and linked content changes, you want to be able to refresh what is displayed.

I am going to assume from your reply that SlideShowNextSlide is the best option and better than SlideShowNextBuildEventHandler  for this purpose.

THanks

Hi Greg,

I tried SlideShowNextBuildEventHandler before I post it. It seems not fire when you switch the slide. So I think SlideShowNextSlide will fit your goal.

Have a good day,

Tom

You are spot on, that is what i found about SlideShowNextBuildEventHandler  in  http://social.msdn.microsoft.com/Forums/en-US/officegeneral/thread/ecdd0b52-135d-4f8f-a0cd-ebdc9cb8168a 

So perhaps things here changed on 2007 / 2010...
