Please update your question first, and highlight your code. Use the 'code' tag immediately above the textarea where you pasted your question

Dibu.net 7-Sep-12 4:41am

I have images for details but how to attach with question ?

Andrei Straut 7-Sep-12 5:06am

No, not images.
Edit your question, and:
in the sections where you have pasted code, simply add <pre> before your code, and </pre> after your code
