Generating a "virtual file"

[Mark Rendle]

Hi

I'm writing a page which outputs CSV data for download. It's all working
fine, setting ContentType to "text/csv", except when the "Open/Save" dialog
appears, the filename shown is "ExportRun.aspx". Is there any way I can
change this to, e.g., "mydata.csv" without having to generate a temporary
file on the server?

Thanks
Mark

Try :

"fname.ext" allows to indicate the name you want to show client side...

Mark,

You need to call AddHeader( ) on the Response to add the "Content-Disposition"
HTTP header and specify a filename (its not one of the standard HTTP headers
that ASP.NET exposes as a property on the HttpResponse class so you have to
use this general-purpose add-a-header method),

Response.AddHeader( "Content-Disposition",
String.Format( "attachment; filename=\"{0}\"",
"mydata.csv"
)
);

Watch letting users enter a value for this filename directly, though, since you're
writing it back out to the HTTP protocol's headers (a hacker could easily craft
a malformed header).

just add this line to the header
(sample in asp)

Response.AddHeader "Content-Disposition", "attachment; filename=" &
SaveFileName

Thanks all for the quick response. Works a treat!
