Question:
When I add an object to a TStrings component, how should I free the
object?


Answer:
Simply call the objects free method. The following example attaches
a icon object to the strings property of a listbox during the forms
creation, and frees the icon when the form is destroyed.

Example:

procedure TForm1.FormCreate(Sender: TObject);
var
  Icon: TIcon;
begin
  Icon := TIcon.Create;
  Icon.LoadFromFile('C:\Program Files\BorlandImages\CONSTRUC.ICO');
  ListBox1.Items.AddObject('Item 0', Icon);
end;

procedure TForm1.FormDestroy(Sender: TObject);
begin
  ListBox1.Items.Objects[0].Free;
end;
