It must be somthing with the strings in the header
actually i've worked with downloading files and this code
Response.ContentType = "application/octet-stream; name=" & oFile.Name
Response.AddHeader("content-disposition", "attachment;filename=" &
oFile.Name);
works perfectly

> I am wanting to allow a client to download a file from a web server and
save it on their local PC. The only way that I have found to do this is to
use HTTP headers. I am using the code shown below (which I have copied with
some variable name changes) from a book on ASP.NET programming. This code
sits in the Page_Load event of a file called 'Download.aspx'. In order to
send a file to the client, this page is called from another page (using
Response.Redirect), passing it the full location of the file to be sent to
the client. Everything works correctly except that the default file name
that appears in the SaveAs dialog box on the client is always
'Download.aspx" rather than the name of the actual file. This happens
despite the use of the "Content-Disposition attachment filename=..." header,
which, according to the comment should set the default file name.
