The simplest way is to write some ADO code (ADODB.Connection/RecordSet) to
get data from the other database. You only need to give the Connection
object a correct ConnectionString.

If the other database is on the same server, you can create a view in SQL
Server to access the data, then use that view as your data source in the
form.  I don't *think* you can use the alternate database directly in the
form, but someone please correct me if I'm wrong.

In any event, it's very easy to create the view, just prepend the name of
the database to the usual owner.table[.field] syntax...in your case, it
would look like this:

   SELECT * FROM SCSAdmin.dbo.MyTable

...or if you wanted to mix & match fields and databases in a join...

   SELECT SCSAdmin.dbo.MyTable.MyField, dbo.TableFromSCSdb.OtherField FROM
SCSAdmin.dbo.MyTable INNER JOIN dbo.TableFromSCSdb ON ...

... you get the idea.  You *can* specify SCSdb in front of anything from the
local database for clarity if you want, but I suspect the query designer
would strip them out.
