I commented this part of code:
(*
with IB_QueryConta.FieldsReadOnly do
begin
Clear;
Add('CCT_CRIACAO=TRUE');
Add('CCT_GRAU=TRUE');
end;
*)
and as you said the program finally works!
Helen, I didn't omit important details from the problem description
voluntary. There is much code involved, it's necessary to resume it.
If I knew previously what is or what is not important, certainly I
would know the solution! This is the price we have to pay when start
using a new tool!
By the way, what's the CODE for declaring those fields as NOEDIT? (I
already know how to do it with Edit Component Field Properties, I
want to know with code)
And after declaring them as NOEDIT, what's the CODE for "undeclaring"
it?
I thank you all!
