Yes, polling using Timer will work fine. I even have an example on www.cflex.net <http://www.cflex.net/> , but it is pretty simple to do.

Please Help Hi Guys Thanks for your different approaches to solve this problem.I will try all of them and see which one will suit my management, but i really appreciate that. I have one solution which recently struck me , please let me know if this is the right one. Can I use the Timer class to create a timer instance which will periodically call HTTP and check which entries are in database and update the dataProvider with the recent entries. Do you guys think this is going to work. i am going to explore all the solutions recommended by you guys and see which is most convenient and efficient to implement with my deadline. Please let me know if Timer thing is going to work for database. Again Appreciate your help Anuj On Tue, Oct 21, 2008 at 7:26 PM, markgoldin_2000 <[EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> > wrote: I have been working on a data pushing solution using Lightstreamer push server.
