current slide show comments

Question

hi all, I share with all my application, I need a single detail.
The idea is that when I change my PowerPoint slide show me the comments slide in my current

works perfect in each slide just shows me the message 2 times andI need to display the message once.

any ideas?

public partial class ThisAddIn
    {
       
        private void ThisAddIn_Startup(object sender, System.EventArgs e)
        {


            Application.SlideShowNextSlide +=new PowerPoint.EApplication_SlideShowNextSlideEventHandler(Application_SlideShowNextSlide);
            
            
            
        }

        private void ThisAddIn_Shutdown(object sender, System.EventArgs e)
        {

 

        }

      
       void Application_SlideShowNextSlide(Microsoft.Office.Interop.PowerPoint.SlideShowWindow Wn)
        {
            Microsoft.Office.Interop.PowerPoint.Slide currentSlide = Wn.View.Slide;
            foreach (PowerPoint.Comment comment in currentSlide.Comments)
            {
                MessageBox.Show(comment.Text);
            }
        }
      

        }





        #region VSTO generated code

        /// <summary>
        /// Required method for Designer support - do not modify
        /// the contents of this method with the code editor.
        /// </summary>
        private void InternalStartup()
        {
            this.Startup += new System.EventHandler(ThisAddIn_Startup);
            this.Shutdown += new System.EventHandler(ThisAddIn_Shutdown);
        }

        #endregion

    }

It would seem that the same text is present in two comments.

You could get around that by changing the loop to:

string lastComment = "";
foreach (PowerPoint.Comment comment in currentSlide.Comments)
{
  if (comment.text != lastComment)
    MessageBox.Show(comment.Text);
  lastComment = comment.text
}
