hi all,

i want to run the slide show say ten slides and then close it programaatically , but in my code given below it opens the slide show and closes immediately ... ..
please give me a solution to this problem


C# Syntax (Toggle Plain Text) 
  1. Microsoft.Office.Interop.PowerPoint.Application ppApp = new Microsoft.Office.Interop.PowerPoint.Application();
  2. 				ppApp.Visible = MsoTriState.msoTrue;
  3. 				Presentations ppPresens = ppApp.Presentations;
  4. 				Presentation objPres = ppPresens.Open(fullPath, MsoTriState.msoFalse, MsoTriState.msoTrue, MsoTriState.msoTrue);
  5. 				Slides objSlides = objPres.Slides;
  6. 				Microsoft.Office.Interop.PowerPoint.SlideShowWindows objSSWs;
  7. 				Microsoft.Office.Interop.PowerPoint.SlideShowSettings objSSS;
  8.  
  9. 				//Run the Slide show
  10. 				objSSS = objPres.SlideShowSettings;
  11. 				objSSS.StartingSlide = 1;
  12. 				objSSS.EndingSlide = objSlides.Count;
  13. 				objSSS.Run();
  14. 				objSSWs = ppApp.SlideShowWindows;
  15.  
  16. 								for (int i = objSSS.StartingSlide; i <= objSSS.EndingSlide; i++)
  17. 				{
  18. 										System.Threading.Thread.Sleep(100);
  19.  
  20. 				}				
  21. 				//Close the presentation
  22. 				objPres.Close();
  23. 				while (System.Runtime.InteropServices.Marshal.ReleaseComObject(objPres) > 0) { };
  24. 				objPres = null;
  25.  
  26. 				while (System.Runtime.InteropServices.Marshal.ReleaseComObject(ppPresens) > 0) { };
  27. 				ppPresens = null;
  28.  
  29. 				ppApp.Quit();
  30. 				while (System.Runtime.InteropServices.Marshal.ReleaseComObject(ppApp) > 0) { };
  31. 				ppApp = null;

I have tried with
C# Syntax (Toggle Plain Text) 
  1. System.Threading.Thread.Sleep(10000);
but not worked.
