note rovf <blockquote><i> i need this on urgent basis thats why i wrote this... if u can't reply then there is no need of your comments. </i></blockquote> If you want a reply, you need to define what's your problem. I assume you are not looking for somebody to write the whole program for you, so presumably you have come to some point, and don't know how to continue from there. But without knowing at which point you are stuck, how could anybody possibly help you? <p> <code> </code> </p> <div class="pmsig"><div class="pmsig-683288"> --&nbsp;<br> Ronald Fischer &lt;ynnor@mm.st&gt; </div></div> 1007268 1007273
