I have an Access database file on my site. I would like to enable people to click on a table name, and download the data that exists in the table.
I'd like to have a link on my page which says Save...
and a combo box with a few ADO ISAMs (xls, text, XML).
When a user clicks on the Save link, the Save As dialog should appear and allow the user to save a file to their local disk. The file would be the data within the table.
I would like to know how to write such code in ADO VB COM or (VBSCRIPT). Should I be using the savetofile or save methods of the Recordset object?

The example from drittich will cause the browser to open an Excel (if Excel is installed) instance on the user's PC and may (I haven't tried this format) put the data into it.
If you really want to target Excel, Chili Reports works pretty well (as a commercial product in this space, but it isn't cheap at all). Otherwise you would want to create an Excel object and use that object to populate an Excel file, that you subsequently download. Ditto for other formats. XML also has libraries (MSXML). For text (CSV) you're on your own.
However, be aware that MSIE has a bug where it will ALWAYS try to open application content in the application that uses that format. For instance, MSIE will always try to open *.doc files in MS Word EVEN if you tell it not to. The ONLY way around this is to zip the files first since MSIE knows to ONLY download *.ZIP files. HTTP directives on disposition do not work with MSIE.

for XML, it's easy. load your recordset, save it using RS.Save and then redirect the browser to it, like this:
<%
StrSQL="Select * From Table"
Set MyRS=DatabaseConnection.Ex
MyRS.Save "c:\inetpub\wwwroot\downlo
Response.redirect "/downloads/RecordsetFile.
%>
for other file formats (plain text, non-xml) you'll probably have to use the Scripting.FileSystemObject
