Hello everybody,

I am currently struggling with a really basic problem:
I have a button which inserts a slide into an active presentation. And I would like to insert it after the currently open slide...

--> Question: How do I find out the currently active slide (in edit mode)?

Thanks a lot and best regards,

Chris

Hello Christian, 

    Public Shared ReadOnly Property CurrrentSlide() As PowerPoint.Slide
        Get
            Dim activeWindow As PowerPoint.DocumentWindow = PowerPointApp.ActiveWindow
            Dim view As PowerPoint.View = activeWindow.View
            Dim currentSlide As PowerPoint.Slide = TryCast(view.Slide, PowerPoint.Slide)
            Marshal.ReleaseComObject(view)
            Marshal.ReleaseComObject(activeWindow)
            Return currentSlide
        End Get
    End Property


{your class}.CurrentSlide.SlideNumber. You might also nee to use {your class}.CurrentSlide.SlideIndex.

As to adding a slide, see http://msdn.microsoft.com/en-us/library/office/ff746586%28v=office.15%29.aspx.

Hello Andrei,

thanks a lot :-)

I already have the insert of the slide done, I "only" needed to know at which slide the user currently is ;-)

I have pasted your code into my VS2013, and receive the following error:
[img]http://zwischenspeicher.net/cloud/public.php?service=files&t=c997a985754bacb994d7f3fd0b641b94[/img]

Sorry the picture doesn't show up, please just click the URL and you can see it ;-)

What would I need to do that the "PowerPointApp" is recognized?

Thanks a lot again!

Best regards,

Chris
