If Listbox1 string exist in Listbox2 then the item should be deleted

Hey all,

I've got a Listbox1 and Listbox2.

Both are filled with about 50-100 strings and sometimes they contain the same string, if they do I would like for (via button1.click) all the items in Listbox1 that already exist in Listbox2 to be deleted from Listbox1.

procedure TForm1.Button1Click(Sender: TObject);
var i : Integer;
begin
     for i := 0 to ListBox1.Items.Count -1 do
          begin
          if ListBox2.Items.IndexOf(ListBox1.Items[i]) > -1 then
               ListBox2.Items.Delete(ListBox2.Items.IndexOf(ListBox1.Items[i]));
          end;
end;
