I am trying to do the simple task of displaying a HTML table in Excel format. I am using the MIME method and have the following code...<BR><BR>Response.ContentType = "application/vnd.ms-excel" <BR>Response.Charset = ""<BR><BR>On some machines, I get the page that prompts you to login as (part of the ASP.NET forms based security which is used for this site) displayed in Excel format. Other times it works fine and the data that is desired is displayed. Any ideas what may be happening?<BR><BR>Thanks,<BR><BR>-b
