Ok what you're doing is actually setting the file for download in the browser. If you want to open the file on the server machine then use the File class and the StreamReader/Writer classes.

If you want to open the file on the client machine, then you will probably need to use ActiveX, but I don't know anything about that. You may find it better asking this question on the ASP forums.
