Thanks,

I have a group of components inherited from a class bases (ATFields call) inserted on a form. If I execute the application (exe) the following function ok works. "f1.Components[i].InheritsFrom(ATField)".

function  OATTRANS.GetATFIELDByHostID(host_id: String; f1 : TForm): ATField;
var
i   : Integer;
fx   : ATField;
begin
for i := 0 to  f1.ComponentCount - 1  do
 begin
 if not f1.Components[i].InheritsFrom(ATField) then
    continue;
 fx := ATField(f1.Components[i]);
 if (fx.FIELDHOSTID = host_id) then
     begin
     result := fx;
     exit;
     end;
  end;
result := nil;
end;

Question :

I have a DLL that uses this function and it does not recognize the class ATFields father?

I'm not sure if I understand you properly, but looking at the code, perhaps you can try

if not (f1.Components[i] is ATField) then
  Continue;

Perhaps you need to use the RegisterClass/RegisterClasses functions?

Anyway where did you declare the ATField and its ancestor classes?
