Question

How to delete created labels. I tried FindComponent but failed , what I have to do? should I set there parent to other component like TPanel or what?

procedure TForm1.Button1Click(Sender: TObject);
var
  lblLink: TLabel;
begin
   for i := 0 to stringtList.Count-1 do
   begin 
     lblLink := TLabel.create(self);

     with lblLink do
     begin
       name:='lblLink'+inttostr(i);
       caption:inttostr(i);
       Parent := self;
       font.style := [fsUnderline];
       cursor := crHandPoint;
       color := clBlue;
       font.Color := clBlue;
     end;
   end;
end;

You can iterate over the Components property, then check for the name of the component and finally free the component.

Var
  LIndex : Integer;
  LComponent : TComponent;
begin
  for LIndex := ComponentCount-1 downto 0 do
    if StartsText('lblLink',Components[LIndex].Name) then
    begin
     LComponent:=Components[LIndex];
     FreeAndNil(LComponent);
    end;
end;
