How to control Ms Powerpoint 2007 Slide show using C# 3.5?

[bhavna_816]

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

Microsoft.Office.Interop.PowerPoint.Application ppApp = new Microsoft.Office.Interop.PowerPoint.Application();
				ppApp.Visible = MsoTriState.msoTrue;
				Presentations ppPresens = ppApp.Presentations;
				Presentation objPres = ppPresens.Open(fullPath, MsoTriState.msoFalse, MsoTriState.msoTrue, MsoTriState.msoTrue);
				Slides objSlides = objPres.Slides;
				Microsoft.Office.Interop.PowerPoint.SlideShowWindows objSSWs;
				Microsoft.Office.Interop.PowerPoint.SlideShowSettings objSSS;

				//Run the Slide show
				objSSS = objPres.SlideShowSettings;
				objSSS.StartingSlide = 1;
				objSSS.EndingSlide = objSlides.Count;
				objSSS.Run();
				objSSWs = ppApp.SlideShowWindows;

								for (int i = objSSS.StartingSlide; i <= objSSS.EndingSlide; i++)
				{
										System.Threading.Thread.Sleep(100);
					
				}				
				//Close the presentation
				objPres.Close();
				while (System.Runtime.InteropServices.Marshal.ReleaseComObject(objPres) > 0) { };
				objPres = null;

				while (System.Runtime.InteropServices.Marshal.ReleaseComObject(ppPresens) > 0) { };
				ppPresens = null;

				ppApp.Quit();
				while (System.Runtime.InteropServices.Marshal.ReleaseComObject(ppApp) > 0) { };
				ppApp = null;

I have tried with

System.Threading.Thread.Sleep(10000);

but not worked.

Can you debug your application, step line by line, and tell us the line where the application closes immediately?

And whilst you are debugging, check that objSlides.Count is greater than zero :)
