Hi Kamal,
you never close the htreads, remember that is your duty to close it when solved assigning a "correct answer". If you find yourself the solution you can add a msg with the solution and mark this msg as correct, in this manner you help people to find quickly a a solution for same issue and don't fill forums with garbage, see please How to close a discussion and why and Are you a responsible person in SCN?.
Regards
Roberto
