How to open and close an instance of powerpoint in C#

Question

Hello I am doing an application in which I launch Office App like Word PowerPoint etc So I did for the Word App but now I am doing for the Powerpoint App but I don't know how to put an event on the exit of an instance of Powerpoint and also create an instance of Powerpoint. Here is what I did for the Word App:   using  wd = Microsoft.Office.Interop.Word;           wd.Application wdApp =  new  wd.Application();       wdApp.Visible =  true ;           ((wd.ApplicationEvents4_Event)wdApp).Quit += () => { MessageBox.Show( Exited! ); };

Hi Tejas My idea is that when I create a presentation a button will be created automatically and when I close it the button must be removed so I need to get the title of the presentation do you have any idea ? Here is what i did: using Powerpoint = Microsoft.Office.Interop.PowerPoint; Powerpoint.Application wdApp = new Powerpoint.Application(); string oldCaption = wdApp.Application.Caption ; string guid = Guid.NewGuid().ToString(); //set caption to random value wdApp.Application.Caption = guid; //create a presentation PresentationpptPresentation=wdApp.Presentations.Add(Microsoft.Office.Core.MsoTriState.msoTrue); //make sure app is visible: wdApp.Visible = true ; //find random value to get process id //here I need to get the title of the presentation int processId = GetProcessIdByWindowTitle(guid); //reset caption wdApp.Application.Caption = oldCaption; //create a dictionary Dictionary int  Button> mapping = new Dictionary int  button>(); //add mapping mapping.Add( new KeyValuePair int  Button>(processId deleteButton)); //found this online: /// /// Returns the name of that process given by that title /// /// Int32MaxValue re public static int GetProcessIdByWindowTitle( string AppId) { Process[] P_CESSES = Process.GetProcesses(); for ( int p_count = 0; p_count { if (P_CESSES[p_count].MainWindowTitle.Equals(AppId)) { return P_CESSES[p_count].Id; } } return Int32.MaxValue; }

Hi Jim In powerpoint you have to do it using presentation you can have multiple presentation using the same instance. Below code snippet will add new presentation. //Createthe new Presentation PresentationpptPresentation=pptApplication.Presentations.Add(MsoTriState.msoTrue); You can find sample at below location. http://www.free-power-point-templates.com/articles/create-powerpoint-ppt-programmatically-using-c/ Also for method APIs you can refer Microsoft's documentation at below location. https://msdn.microsoft.com/en-us/library/microsoft.office.interop.powerpoint.aspx Hope this will help you out.

Hi Tejas if I want to open multiple instances of PPT how I have to do it ? Because in Word with this code I can create multiple instances easily.

Hi Jim For power point also you can write the very similar kind of code. using PowerPoint=Microsoft.Office.Interop.PowerPoint; var app = new PowerPoint . Application (); app.P resentationClose+=() =>{}; if above code does not work you can also simply close it using its process. Process[]pros=Process.GetProcesses(); for ( int i=0;i { if (pros[i].ProcessName.ToLower().Contains( powerpnt )) { pros[i].Kill(); } } Hope this will help you out. Feel free to write if you need more information on this. Please don't forget to mark as answer if this helps
