Arrange a list alphabetically

{ You need a TListBox and a TButton. With a few modifications, you can use it with any variable compatible with a TStringList. If you change the operator "<" for a ">" in the 'if' clause below, the order will be reversed } procedure TForm1.Button1Click(Sender: TObject); var i, x: Integer; begin for i := 0 to (ListBox1.Items.Count - 1) do for x := 0 to (ListBox1.Items.Count - 1) do if (ListBox1.Items[x] < ListBox1.Items[i]) and (x > i) then begin ListBox1.Items.Insert(i, ListBox1.Items[x]); ListBox1.Items.Delete(x + 1); end; end;
