Thanks Richard, for the motivation, and thanks to the group as well for the crude php code. i am working on this problem now. To tell you the truth i am a c programmer but now i have moved to php. At first i thought that asp will be best to experiment but after doing some research i found that asp is moving towards a slow death.So friends, finally i am in php community.Let me confess,i am not very experienced in php ,but very soon i will be as experienced as you are (of course i will need your help).
