<p class=MsoNormal style='margin-bottom:12.0pt'>Hi all,<br>
<br>
I came across a strange bug(???) in latest versions of Delphi.<br>
<br>
Have a look at the following code.<br>
<br>
procedure TForm1.Button1Click(Sender: TObject);<br>
var<br>
i : integer;<br>
begin<br>
ComboBox1.Clear;<br>
ComboBox1.Items.AddObject('All Locations', TObject(-1));<br>
ComboBox1.Items.AddObject('Only this Location', TObject(0));<br>
ComboBox1.Items.AddObject(Test Location', TObject(1));<br>
<br>
i := Integer(ComboBox1.Items.Objects[0]);<br>
showmessage(inttostr(i));<br>
end;<br>
<br>
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 <br>
List index out of bounds error. Also I am getting -1 without any error when I
tried this code in Delphi 3. <br>
<br>
Is it a bug in latest version of Delphi ? Any help is appreciated.<br>
<br>
Thank you<br>
<br>
Regards,<br>
Sinu<o:p></o:p></p>
