@WHE, @john_dennis

I use the following script to get the Name of the selected event, but I changed the script to get the MediaPath (full path) of the selected event.

/**
Get MediaPath of selected event (take) and copy to clipboard
Rob Johnston
 **/
using System;
using System.Collections.Generic;
using System.Globalization;
using System.Windows.Forms;
using ScriptPortal.Vegas;

public class EntryPoint
{
    Vegas myVegas;

    public void FromVegas(Vegas vegas)
    {
                
     foreach (Track track in vegas.Project.Tracks)
     {
          foreach (TrackEvent evnt in track.Events) 
         {
            if (evnt.Selected)
        {
            foreach (Take take in evnt.Takes)
            {    
                if (take.IsActive)
                  {
                    Clipboard.SetText(take.MediaPath);
                    MessageBox.Show(take.MediaPath);
                    return;
                            }
            }
        }
             }
         }            
    }  
}
