    Streaming PDF to IE 6.0 browser

    Hi all misters,

    I hope someone can help me here.

    Here is my problem.

    I stream the PDF files to the browser because they contain private
    information and they are not located within the web site itself. The
    application opens the PDF file and then streams it to the browser. I call to
    ASPX page like this: ShowFile.aspx?I DFILE=100&NAME= 000040.pdf.

    The aspx page calls WCF service and gets all bytes of a PDF file.

    When streams bytes of PDF file to browser, Acrobat Reader OCX reads bytes
    and shows PDF, the user can save PDF to disk file with a name.

    I want that the filename could be the NAME querystring parameter.

    I try but doesn't works fine.

    Here is the code that I use:

    Thanks for any help you can offer, thanks in advance, any help will be very
    grateful, regards, greetings



    Response.Buffer = True '//<<- Va con el Response.Flush( );

    'Response.Buffe rOutput = True

    Response.Clear( )

    Response.ClearC ontent()

    Response.ClearH eaders()

    'Response.Cache Control = "Private" 'Public



    Response.AddHea der("Accept-Header", tamanoFichero.T oString())

    Response.AddHea der("Content-Size", tamanoFichero.T oString())

    Response.AddHea der("Content-Length", tamanoFichero.T oString())

    Dim abrirEnAcrobatR eader As Boolean = False

    If abrirEnAcrobatR eader Then

    ' Aparecería un cuadro de diálogo para Abrir o Guardar fichero

    Response.AddHea der("Content-Disposition", "attachment ; filename=" +
    Path.GetFileNam e(nombreFichero ))

    Else

    Response.AddHea der("Content-Disposition", "inline;filenam e=" + nombreFichero)

    End If

    'Response.AddHe ader("Content-Disposition", "attachment ; filename=" & fn)

    Response.AddHea der("Cache-Control", "private")





    '//Set the output stream to the correct content type (PDF).

    Response.Conten tType = sMimeType

    'Response.AddHe ader("Content-Type", sMimeType)

    Response.AddHea der("Accept-Ranges", "bytes")

    Response.Charse t = ""

    Response.Binary Write(infoFiche ro.ContenidoFic hero)

    Response.Flush( )

    'Response.Write File(fichero)

    'Response.Close ()

    Response.End()

      Maybe this code below is a problem? What has
      infoFichero.Con tenidoFichero exactly, did you check it?
      Response.Binary Write(infoFiche ro.ContenidoFic hero)

          Thanks, mister.

          ContenidoFicher o is Byte(), array of bytes of the file.

          I'm sure, that I get all bytes right.

          Greetings.

              Oh, sorry, now I see what the question is. You added the file name for
              the download stream at the following line

              Response.AddHea der("Content-Disposition", "attachment ; filename=" +
              Path.GetFileNam e(nombreFichero ))

              The Filename parameter is used to suggest a file name in the download
              dialog. I think you would need to change it

              Response.AddHea der("Content-Disposition", "attachment ; filename=" +
              Request.QuerySt ring("NAME"))
