Response.WriteF ile help please

[Scott C. Reynolds]

I want to serve a PDF right to a web page (cannot link browser directly
to PDF file). Stumbled across Response.WriteF ile this morning. On my
machine (XP Pro) this worked fine:

private void Page_Load(objec t sender, System.EventArg s e)
{
string filePath = "c:\\somepath\\ some.pdf";
Response.Conten tType = "Applicatio n/pdf";
Response.WriteF ile(filePath);
}

Hit the page in Firefox, PDF loads right up. Hit it in IE, nothing.
Just a broken puzzle icon.

Further, one of the developers on my team did the exact same thing and
it doesn't work at all. IE prompts him to save or open, which will save
the PDF (but it opens as a .aspx so he gets PDF gibberish in VS.NET if
he chooses open), and in Firefox he gets a message about the file being
corrupt.

The eventual goal is to do the same with a file on another computer (not
on the web server), so the questions are:

1)Why isn't it working properly in IE?
2)Why would it work on one machine and not another?
3)Any other tips regarding this?

Thank you very much in advance.

Scott.

Use this code to set the filename so it won't be downloaded as an aspx file.

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

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

doing that makes IE prompt for save/open, if you hit open, it prompts
again for save/cancel. it breaks the functionality in firefox.

Is there a better way, assuming I can't link directly to the PDF?

Hello Scott,

You will want to make sure that you clear everything before you write out.

[C#]
Response.ClearC ontent();
Response.ClearH eaders();
Response.Conten tType = "applicatio n/pdf";
Response.AddHea der("Content-disposition", "inline;filenam e=test.pdf");

Response.WriteF ile(file);
Response.Flush( );
Response.End();

I'm doing it exactly this way, and it works no matter where I run it from
(or which browser).

You should also set the Content-Length header, since some older Acrobat
Reader plug-ins require this.

Hi Matt,

Do you know if this approach works for other content-types as well?
Such as jpegs (image/jpeg) and Excel files (application/excel) etc.

I need to write a 'fileservice' page that will (based on a querystring
parameter) fetch a file from the server and blast it back to the
client. The documents accessed could be any file type imaginable. I
was planning on writing HttpHandlers for the various content types,
but Response.WriteF ile sounds like the silver bullet I was looking
for. Any thoughts?

Thanks,
Roger

Hello Roger,

It does. Of course, you'll have to change the ContentType.

I have done exactly what you describe in several solutions, however instead
of WriteFile, I use BinaryWrite to write out a byte array. If you have them
on the filesystem already, using WriteFile will work just fine.

A lot of times, Ill store images in the database and stuff them into the
cache on first load.

Okay...I wrestled this all weekend, trying both WriteFile and
BinaryWrite. I couldn't get it to work. It turns out, in IE, if you
are using the full version of Acrobat then it hoses. But if you are
using the reader as the browser plugin then it's fine. So thanks for
the help. I was going crazy on this because it's such simple code.
Just something for the rest of you to be mindful of - Acrobat = bad!

Hello Scott,

I do know that Adobe is rather buggy, and one thing that I found helped me
was to make the url end in .pdf

For example: the link that calls this code should look something like:

http://localhost/MyTestApp/GetFile.a...ame=report.pdf

For some reason, adding the extension there helps IE and Adobe out.
