Filesystemwatcher triggers multiple events for one file

Here is the relevant code:

    // PDFfileWatcher
    //
    this.PDFfileWatcher.EnableRaisingEvents = true;
    this.PDFfileWatcher.IncludeSubdirectories = true;
    this.PDFfileWatcher.SynchronizingObject = this;
    this.PDFfileWatcher.Changed += new System.IO.FileSystemEventHandler(this.PDFfileWatcher_Created);


    private void PDFfileWatcher_Created(object sender, System.IO.FileSystemEventArgs e)
    {
        string PdfChangeType = e.ChangeType.ToString();
        MessageBox.Show("Something Created: " + e.Name.ToString() + " " + e.ChangeType);
    }
    private void PrintTextFileHandler(object sender, PrintPageEventArgs ppeArgs)
    {
        //Get the Graphics object
        Graphics g = ppeArgs.Graphics;
        float linesPerPage = 0;
        float yPos = 0;
        int count = 0;
        //Read margins from PrintPageEventArgs
        float leftMargin = ppeArgs.MarginBounds.Left;
        float topMargin = ppeArgs.MarginBounds.Top;
        string line = null;

        //Calculate the lines per page on the basis of the height of the page and the height of the font
        linesPerPage = ppeArgs.MarginBounds.Height /
        CourierNew11Font.GetHeight(g);
        //Now read lines one by one, using StreamReader
        while (count < linesPerPage &&
        ((line = reader.ReadLine()) != null))
        {
            //Calculate the starting position
            yPos = topMargin + (count *
            CourierNew11Font.GetHeight(g));
            //Draw text
            g.DrawString(line, CourierNew11Font, Brushes.Black,
            leftMargin, yPos, new StringFormat());
            //Move to next line
            count++;
        }
        //If PrintPageEventArgs has more pages to print
        if (line != null)
        {
            ppeArgs.HasMorePages = true;
        }
        else
        {
            ppeArgs.HasMorePages = false;
        }
    }
    private void Print_Click(object sender, EventArgs e)
    {
        // Start PDFfileWatcher
        ToBePaidPath = textboxToBePaidPath.Text;
        PDFfileWatcher.Path = ToBePaidPath;
        PDFfileWatcher.Filter = "*.*";
        PDFfileWatcher.IncludeSubdirectories = false;

        //Start PDFfileWatcher
        if (PDFfileWatcher.EnableRaisingEvents == false)
        {
            try
            {
                //Begin monitoring.
                PDFfileWatcher.EnableRaisingEvents = true;
                MessageBox.Show("PDFfileWatcher is active");
            }
            catch (IOException ex)
            {
                MessageBox.Show("There was an error starting the PDF file monitor...Error was: " + ex.Message);
            }
        }
        string fileContent = HiddentextBox1.Text.ToString();
        //Create a StreamReader object

        try
        {
            reader = new StreamReader(fileContent);
            //Create a CourierNew font with size 11
            CourierNew11Font = new Font("Courier New", (11), FontStyle.Bold);

            //Create a PrintDocument object
            PrintDocument pd = new PrintDocument();

            // Set Margins width
            Margins margins = new Margins(5, 5, 30, 25);
            pd.DefaultPageSettings.Margins = margins;

            //Add PrintPage event handler
            pd.PrintPage += new PrintPageEventHandler(this.PrintTextFileHandler);
            //Call Print Method
            pd.Print();

        }
        catch (IOException ex)
        {
            MessageBox.Show("Error was: " + ex.Message, MessageBoxButtons.OK, MessageBoxIcon.Error);
        }
        finally
        {
            //Close the reader
            if (reader != null)
                reader.Close();
        }
    }

Note, that when the print function runs, I have it set up to print to the default printer, in which my case is "Adobe PDF".  A dialog appears which is triggered by save PDF printer where I can name the PDF file as I choose.  It is at this stage that the file watcher detects about 4 created events.  I'm assuming that the watcher is picking up some sort of temporary files, however the messagebox echoes the name of the same PDF file created 4 times.  If I can filter the routine to only echo once, that would be great. 

If I change the event to only detect "changed" events, then only one notification comes up.  However I need to be able to detect "Created" PDF files, and PDF files that have been modified afterwards with the same watcher if possible, so that either one of the 2 events will do a different action that I choose. (eg INSERT on created, and UPDATE on Changed events to the SQL database).
