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?IDFILE=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();

Maybe this code below is a problem? What has
infoFichero.ContenidoFichero exactly, did you check it?

Thanks, mister.

ContenidoFichero is Byte(), array of bytes of the file.

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

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

Response.AddHeader("Content-Disposition", "attachment; filename=" +
Path.GetFileName(nombreFichero))

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

Response.AddHeader("Content-Disposition", "attachment; filename=" +
Request.QueryString("NAME"))
