Duplicate Slides Insertion using CommandBars.ExecuteMso("PasteSourceFormatting")

Question

Hello,

I am copying all slides from a Presentation (PowerPoint 2003) to another presentation (PowerPoint 2010). I am not sure what I missed, when I executed the code below, I got the same number of slides on the destination presentation but each slide is the same last slide on the source. Any idea? Thanks!

private void InsertWithKeepSourceFormatting(Microsoft.Office.Interop.PowerPoint.Presentation source,
            Microsoft.Office.Interop.PowerPoint.Presentation target)
        {
             foreach (Slide slide in source.Slides)
            {
                slide.Copy();
                int y = slide.SlideID;
                target.Windows[1].Activate();
                Globals.ThisAddIn.Application.CommandBars.ExecuteMso("PasteSourceFormatting");
               
            }
       }

Hi May-Yin,

Thanks for posting in the MSDN Forum.

I can't reproduce your issue. the following snippet is used to check your scenario on my side:

            PowerPoint.Presentation target =  Globals.ThisAddIn.Application.ActivePresentation;
            PowerPoint.Application ap = new PowerPoint.Application();
            PowerPoint.Presentation ps = ap.Presentations.Open(@"C:\Users\v-yangxu\Desktop\Presentation1.pptx");
            ap.Visible = Microsoft.Office.Core.MsoTriState.msoTrue;
            foreach (PowerPoint.Slide slide in ps.Slides)
            {
                slide.Copy();
                int y = slide.SlideID;
                target.Windows[1].Activate();
                Globals.ThisAddIn.Application.CommandBars.ExecuteMso("PasteSourceFormatting");
            }
            ap.Quit();

There hasn't duplicate slide between two presentations.

Have a good day,

Tom
