I'm having a little trouble with an application I'm developing in Delphi.  

Whenever a particular code segment executes, Delphi reports "List index out of
bounds".

Here's the code segment it stops at:
     StringList.Strings[0] := inttostr(TabbedNotebook1.PageIndex);

Any help would be greatly appreciated.

In article <bitzm.1514.00899...@columbia.dsu.edu>, bi...@columbia.dsu.edu (Mike Bitz) says:

Has
StringList.Create
been executed.
Have you executed the create but also
StringList.Free

Good luck

To add a string to the list, call the Add or Insert method. You cannot
refer to an index before anything is added to the list.

If your list is empty, the above doesn't work. Instead use
StringList.Add(...).

You have insert n:th string before you change it. Check the example below.
(MyList type is TStringList.)

procedure TForm1.InsertClick(Sender: TObject);
begin
  { First insert item to n:th position. However n can't be greater
    than MyList.Count or you'll get List index out of bounds. }
  MyList.Insert(0, IntToStr(Form1.Tag));
end;

procedure TForm1.ChangeClick(Sender: TObject);
begin
  { After you have inserted n:th item you can change it with
    Strings[n] property. }
  MyList.Strings[0] := IntToStr(Form1.Tag);
end;
