I need to know how to setup and use an ODBC connection to SQL Server
through the web.config file.
I have done a connection using OLEDB but not with ODBC.  Here's what I
have with the OLEDB.

Web.Config
<add key="connectionString" value="data source=Testdb1; initial
Catalog=Test; user=tester; password=test"/>

In the code
Dim conn As SqlConnection = New
SqlConnection(ConfigurationManager.AppSettings("connectionString"))
Conn.open

I have an ODBC datasource setup already called TestDS.   So how would
I setup my web.config file to use TestDS and what would my code look
like to open it.

Thanks
