Hi guys,
How to solve this problem??

Google is your friend: Be nice and visit him often. He can answer questions a lot more quickly than posting them here...

A very quick search gave over 300,000 hits: Google[^]

In future, please try to do at least basic research yourself, and not waste your time or ours.
