Yes, this is Delphi 'internal feature' ;)
You can use everything except -1.

Hi all,
I came across a strange bug(???) in latest versions of Delphi.
Have a look at the following code.
procedure TForm1.Button1Click(Sender: TObject);
var
i : integer;
begin
ComboBox1.Clear;
ComboBox1.Items.AddObject('All Locations', TObject(-1));
ComboBox1.Items.AddObject('Only this Location', TObject(0));
ComboBox1.Items.AddObject(Test Location', TObject(1));
i := Integer(ComboBox1.Items.Objects[0]);
showmessage(inttostr(i));
end;
When I tried to run this code in Delphi 6 and Delphi 2007 , I am getting List
Index out of bounds[0] error in Showmessage. When I tried -2, -3, -4… instead
of -1 object , I got the proper output without any
List index out of bounds error. Also I am getting -1 without any error when I
tried this code in Delphi 3.
Is it a bug in latest version of Delphi ? Any help is appreciated.
Thank you
Regards,
Sinu
