Here,I would like to share the knowledge which i have learnt by solving the similar kind of issues. And that may help the others to learn and explore.
Please correct me if i'm wrong.
I understand that you're trying to help, but when you give general examples rather than specific examples, people get confused (as in this thread). They often think you're telling them how to do what they asked for and don't understand that you're just trying to point them in the right direction. This invariably leads to a series of posts about why your solution doesn't work for them which clutters up the thread. It's really better if you let me (or Kolusu) answer the questions specifically rather than trying to point people in the right direction (which hardly ever seems to work on this board). I hope you understand my point.
