    At CE. we have a "No Free Lunch" policy. This means you will not be provided with a program. Instead you will be provided help if and when you get stuck. Post in this thread, what you have tried/done till now and the members of CE with experience in this type of work will help you out by telling you where you went wrong and set you on the right course.

    P.S. Do not post the same question in different threads. Also your question should be posted in an appropriate section or thread, do not post randomly anywhere. I have deleted your duplicate question in another thread.
