You can tell it the filename by added this header just before you do the write:

Response.AddHeader("Content-Disposition", "attachment;filename=test.aaa")

Hi, i'm tryng to make a asp.net file manager to download files that are on a
server;
supposing i want to download the file c:\test\test.aaa, the code i have
written is:


#########################################

Dim fStream As New System.IO.FileStream(path & file, _
IO.FileMode.Open, IO.FileAccess.Read, IO.FileShare.Read)

Dim b(fStream.Length) As Byte

Response.Clear()
Response.ClearContent()
Response.ClearHeaders()

Response.ContentType = "application/unknown"

fStream.Read(b, 0, fStream.Length)

Response.BinaryWrite(b)

Response.End()

fStream.Close()
fStream = Nothing

#####################################

this method works fine, but there are 2 problems:
1. when the dialog for file saving appears, it prompt to save a file with
the name of the aspx page, and not with the name of the file being
downloaded;
2. i suppose that it is not very efficient to open the file with filestream,
copy it into a byte array and then output it to the page: there is some
method more efficient??

Thanks, Mik

Thanks! it works fine;
any ideas about the code efficiency?

Hi Mik,

Sorry, not sure what efficiency you're referring to. The use of AddHeader adds
very very little to the output.
