Thanks for your reply,

but what I want to do is

on iboquery.beforepost do

for i:= 0 to iboquery.fieldcount-1 do
begin
if (iboquery.fields[i].isnull) and (iboquery.fields[i].required)
then
showmessage('filed '+
iboqurey.fields[i].displaylabel
//user didnot know the fieldname -- ivno
//user only see the field displaylabel == invoice no
+ ' must fill value!!')

end;
