I do not recommend using the database access method from the form. This will only work on a Windows machine
as it uses OLEDB to do th econnection and you will have to configure a DSN on each machine that wants to connect to the DB. Lastly the DB must be on the same physical network as the machine where the form is running. A web service access alleviates all of these restrictions.
In either case if you are using Reader you will have to Reader Extend the form to allow it to make DB or Web Service calls from th eform. Only Reader Extensions server will turn on that right for you.
