Hello Paul,

you are right, that's another way to do it. Now I don't have any
access violations any longer, but my code is still not working :-(

with :

procedure IB_DataSourceDataChange(Sender: TIB_StatementLink;
Statement: TIB_Statement; Field: TIB_Column);
begin
if (Field<>NIL and Field.FieldName='myField') then...

end;

these condition seems to be NEVER true !!?? More than this. If I try
to look which Fields are passing through with:

if Field<>NIL then showMessage(Field.FieldName);

nothing happens. Strange.

Any comments?
