Question

I am trying to save selected slide so it doesnt retain my source template. how do i retain the existing template while i save the slides

   private void SaveSelectedSlide_Click(object sender, RibbonControlEventArgs e)
    {
        try
        {
            PowerPoint.Application ppApp = Globals.ThisAddIn.Application;
            PowerPoint.SlideRange ppslr = ppApp.ActiveWindow.Selection.SlideRange;
            string desktop = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
            var temporaryPresentation = Globals.ThisAddIn.Application.Presentations.Add(Microsoft.Office.Core.MsoTriState.msoTrue);
            Microsoft.Office.Interop.PowerPoint.CustomLayout customLayout = ppApp.ActivePresentation.SlideMaster.CustomLayouts[Microsoft.Office.Interop.PowerPoint.PpSlideLayout.ppLayoutText];

            for (int i = 1; i <= ppslr.Count; i++)
            {
                var sourceSlide = ppslr[i];
                sourceSlide.Copy();

                var design = sourceSlide.Design;
                temporaryPresentation.Slides.Paste();


            }

            temporaryPresentation.SaveAs("Temporary", Microsoft.Office.Interop.PowerPoint.PpSaveAsFileType.ppSaveAsPresentation, Microsoft.Office.Core.MsoTriState.msoTrue);

            temporaryPresentation.Close();

        }
        catch (COMException Ex)
        {
            Debug.WriteLine("Some problem" + Ex.Message + Ex.StackTrace);
            MessageBox.Show("PLease enter text ");
        }

    }

Is the presentation changed when you call the [SaveAs](https://msdn.microsoft.com/en-us/library/office/ff746389(v=office.15).aspx) method of the Presentation class? — Eugene Astafiev, Feb 25 '15 at 13:58
This code works pretty fine when I tested it. What exactly is the problem here? — Pilgerstorfer Franz, Feb 25 '15 at 15:00
when the slides get saved the blank template are used. if we use some template it wont select that template. it juzt copies all shapes to destination. without source template. — test, Feb 25 '15 at 18:00
@EugeneAstafiev yes we are creating another temporary presentation and copying all the source file data to that temporary presentation — test, Feb 26 '15 at 05:34

I think I got what you want. When pasting the new slide, save the new SlideRange. Afterwards assign the design of the source slide.

PowerPoint.Application ppApp = Globals.ThisAddIn.Application;
PowerPoint.SlideRange ppslr = ppApp.ActiveWindow.Selection.SlideRange;
string desktop = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
var temporaryPresentation = Globals.ThisAddIn.Application.Presentations.Add(Microsoft.Office.Core.MsoTriState.msoTrue);
Microsoft.Office.Interop.PowerPoint.CustomLayout customLayout = ppApp.ActivePresentation.SlideMaster.CustomLayouts[Microsoft.Office.Interop.PowerPoint.PpSlideLayout.ppLayoutText];

for (int i = 1; i <= ppslr.Count; i++)
{
    var sourceSlide = ppslr[i];
    sourceSlide.Copy();

    var design = sourceSlide.Design;                    
    SlideRange sr = temporaryPresentation.Slides.Paste(); // get newly created slideRange
    sr.Design = sourceSlide.Design; // manually set design
}
temporaryPresentation.SaveAs("Temporary", Microsoft.Office.Interop.PowerPoint.PpSaveAsFileType.ppSaveAsPresentation, Microsoft.Office.Core.MsoTriState.msoTrue);
temporaryPresentation.Close();

It worked for me. Please let me know if this is the expected behaviour!
