Thanks Winger,<br><br>But the dets records wont update, It only stores at the files and retrieved when needed in this application. and as I mentioned in a previous mail a new dets file is created every hour and named according to the date.
<br>so i don't think I can apply this to it.<br><br>thanx<br><br>chamila<br><br><div><span class="gmail_quote">On 12/22/06, <b class="gmail_sendername">Ulf Wiger</b> <<a href="mailto:ulf@wiger.net">ulf@wiger.net</a>

<br>If you wrap your dets calls with an access module, you<br>can for example add a second dets file which uses another<br>attribute as the key. You can make this a bag table.<br><br>One thing you need to do when updating an object, is to retrieve
