So if I understand correctly, the problem that you're having is that an
existing database field is being modified by someone other than the application
author, and as a result the application can lose data? In my experience I've
seen table columns modified to be wider, but never reduced in size in an
established database.

If a column were to be changed from, say, varchar(100) to a full text
field, would the control change from a textbox to an edit control? If the
column were to be removed from the database entirely, would that mean that the
control would not be created?
I guess I'm not clear on what exactly the problem is, and what you're
proposing as a solution.
