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

Jim Tat

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 < P_CESSES.Length; 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.

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.
usingPowerPoint=Microsoft.Office.Interop.PowerPoint;
var app = new PowerPoint.Application();
app.PresentationClose+=() =>{};

if above code does not work, you can also simply close it using its process.
Process[]pros=Process.GetProcesses();
for(inti=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.
