With TDBCheckBox, there are two properties that you can set in
design-time or in run-time(as Helen already pointed out). Those
properties are ValueChecked and ValueUnchecked. By default, they are
set to True and False, but they can be changed to whatever value you
need. As an example, I assign them as follows ValueChecked:='T' and
ValueUnchecked:='F'. You can use whatever value you need for those
properties. And, I did the same exercise 5 years ago when I migrated
a Paradox application to Firebird using Delphi 5 and IBO.
