Question

Hello,


i have read the follow tip:

http://www.delphi-zone.com/2010/11/how-to-save-object-configuration-data-easily/

but I have the following structure, and the FPanel[2] Object (4 exists) only one will be saved.
They are stacked into the same parent ....


  TMainWindow = class
  public
    FForm: TForm;
    FPanel: Array [0..2048] of TPanel;
    FLabel: Array [0..2048] of TButton;
  end;

var
  FMainWindowArray : Array [0..2048] of TMainWindow;


thanks fpr hints
