Hi
I try to convert ppt to video:;
i know that CreateVideo is part of presentation. but, when i try this i have this error:
Inline Code Example Here

Looks like createvideo is not part of presentation.

Microsoft.Office.Interop.PowerPoint.Application pptApplication = new Microsoft.Office.Interop.PowerPoint.Application();

            Microsoft.Office.Interop.PowerPoint.Slides slides;
            Microsoft.Office.Interop.PowerPoint._Slide slide;
            Microsoft.Office.Interop.PowerPoint.TextRange objText; 

            // Create the Presentation File
            Presentation pptPresentation = pptApplication.Presentations.Add(MsoTriState.msoTrue);

            Microsoft.Office.Interop.PowerPoint.CustomLayout customLayout = pptPresentation.SlideMaster.CustomLayouts[Microsoft.Office.Interop.PowerPoint.PpSlideLayout.ppLayoutText];

            // Create new Slide
            slides = pptPresentation.Slides;
            slide = slides.AddSlide(1, customLayout);

            Microsoft.Office.Interop.PowerPoint.Shape shape = slide.Shapes[1];

            string picturePath = Directory.GetCurrentDirectory()+ @"/Untitled.jpg";            
            slide.Shapes.AddPicture(picturePath, MsoTriState.msoTrue,
            MsoTriState.msoFalse, shape.Left, shape.Top, shape.Width, shape.Height);

            slide = slides.AddSlide(2, customLayout);
            slide.Shapes.AddPicture(picturePath, MsoTriState.msoTrue,
            MsoTriState.msoFalse, shape.Left, shape.Top, shape.Width, shape.Height);

            Microsoft.Office.Interop.PowerPoint.Presentation preVideo;
            preVideo.CreateVideo("movie.mwv");      //ERROR

Microsoft.Office.Interop.PowerPoint.Presentation preVideo; You declare the variable here but never assign an object to it.

Just use pptPresentation.CreateVideo("movie.wmv"); instead. Should work.

Thanks Ketsuekiame
I have an error with yours recommendation (I do try catch for debugging)

Ok, it seems that we've both misunderstood what this method does. What you're actually asking it to do is put a video INTO your presentation. What you actually need to do is call SaveCopyAs with the type PpSaveAsFileType.PpSaveAsWMV

Be warned that this can be a long process. It might be wise to display a dialog to indicate that your program is doing something while this happens.

thanks about yours support.
I simply miss the required path

it is solved

string movie = Directory.GetCurrentDirectory() + @"/movie.wmv";
pptPresentation.CreateVideo(movie);
