iTextSharp-generated PDFs cause save dialog when closing

Question

I am using iTextSharp to generate PDF documents, and save them to disk like this:

        Document document = new Document(PageSize.LETTER, 50, 50, 80, 50);
        FileStream fs = new FileStream(Ruta, FileMode.OpenOrCreate, FileAccess.ReadWrite, FileShare.ReadWrite);
        PdfWriter PDFWriter = PdfWriter.GetInstance(document, fs);

        EsquemaFormato PageEventHandler = new EsquemaFormato();
        PageEventHandler.Title = TitleMiddle;
        PageEventHandler.TitleHeaderFont = FontFactory.GetFont(BaseFont.HELVETICA, 12, Font.NORMAL);
        PageEventHandler.TitleRightHeaderFont = FontFactory.GetFont(BaseFont.HELVETICA, 9, Font.NORMAL);
        PageEventHandler.HeaderLeft = "Nombre";
        PageEventHandler.HeaderRight = TitleRight;
        PageEventHandler.RutaImagen = RutaImagen;
        PageEventHandler.Cuerpo = Cuerpo;
        PDFWriter.PageEvent = PageEventHandler;

        document.Open();
        document.Close();

Based on http://www.mazsoft.com/blog/post/2008/04/30/Code-sample-for-using-iTextSharp-PDF-library.aspx

I open any PDF file I just created, but when I try to close it causes a "Do you want to Save?" dialog to appear. This does not happen with PDFs that are not generated with iTextSharp.

What am I missing? I've seen solutions using Response but I don´t use it. Thanks in advance.

Update: Here is a sample http://dl.dropbox.com/u/4582874/test.pdf

EDIT: By following Bruno's link I found this post: iTextSharp + FileStream = Corrupt PDF file

That did the trick! Here is my working code now:

    public void CreatePDF(string TitleMiddle, string Ruta, string RutaImagen, string TitleRight, string Cuerpo)
    {
        using (MemoryStream ms = new MemoryStream())
        {
            Document document = new Document(PageSize.LETTER, 50, 50, 80, 50);
            PdfWriter PDFWriter = PdfWriter.GetInstance(document, ms);

            EsquemaFormato PageEventHandler = new EsquemaFormato();
            PageEventHandler.Title = TitleMiddle;
            PageEventHandler.TitleHeaderFont = FontFactory.GetFont(BaseFont.HELVETICA, 12, Font.NORMAL);
            PageEventHandler.TitleRightHeaderFont = FontFactory.GetFont(BaseFont.HELVETICA, 9, Font.NORMAL);
            PageEventHandler.HeaderLeft = "Nombre";
            PageEventHandler.HeaderRight = TitleRight;
            PageEventHandler.RutaImagen = RutaImagen;
            PageEventHandler.Cuerpo = Cuerpo;
            PDFWriter.PageEvent = PageEventHandler;

            document.Open();
            document.Close();
            byte[] content = ms.ToArray();
            using (FileStream fs = File.Create(Ruta))
            {
                fs.Write(content, 0, (int)content.Length);
            }
        }
    }

Can you also post a sample pdf generated by your code for further inspection? — mkl, Oct 24 '12 at 18:17

mkl, how can I post a sample pdf here? I can't find an attach file option — rvidaurric, Oct 24 '12 at 18:49

Have you tried it without the FileAccess.ReadWrite, FileShare.ReadWrite properties?

I create PDF's using itextSharp everyday and have never ran into this issue - main difference between your code and mine is i don't have these.

I suspect the FileShare is leaving the document somewhat open, waiting for someone to finalise closing it with a save?

FileStream fs = new FileStream(Ruta, FileMode.OpenOrCreate); // i get the same problem – rvidaurric Oct 24 '12 at 19:16
close your filestream too. either that or create the new filestream inline with your GetInstance. PdfWriter.GetInstance(document, new FileStream(Ruta, FileMode.OpenOrCreate)); – Darren Wainwright Oct 24 '12 at 19:20
It worked too (i'd already edited my post with another solution), thanks! – rvidaurric Oct 24 '12 at 19:24
