I'm developing a Web App in C#. The following method executes without
exceptions but the database does not get changed. The data is changed in the
record[0] at the point prior to executing the   " adapter.Update(record);"
instruction.

Is there something else I should be doing to insure the update to take
effect???

Thanks, Neil
