Alain's class on Excel 2002 (XP)

[Anon]

Hello,
I've been using for a while Alain samoun's excel.php class on excel 2000.

Now I've moved to Excel 2002 (XP), and the property setting does not work anymore.

It fails on
[...]
$this->ex->application->DisplayAlerts = "False";

Excel gives an exception on Propput().

Any idea on that?
thanks a lot,
