Can I use this method to find a component in runtime? It coud raise a memory leak or something?

var
  i: Integer;
  c: TUniDBCheckBox;
begin
  for i := 1 to 20 do  
  begin
    c := FindComponent('somename' + i.toString) as TuniDBCheckBox; 
    if c <> nil then
    begin
      if c.checked then
        dosomething;
    end;
  end;
end;

Maybe don't do the "as TUniDBCheckBox" where you execute FindComponent....but do a sanity check if the component "is TUniDBcheckBox" first.

var
  i: Integer;
  c: TComponent;  <<---- use TComponent here
begin
  for i := 1 to 20 do
  begin
    c := FindComponent('somename' + i.toString);
    if (c <> nil) and (c is TUniDBCheckBox) then  <<---- sanity check here
    begin
      if (c as TUniDBCheckBox).checked then  <<---- cast here
        dosomething;
    end;
  end;
end;
