Hi,
This is a similar post like many before. It would be good if you can
look through the archives before posting a query to confirm that its
not been asked yet. This mailing list has a lot of advice in its
archives. Also its considered rude to ask your question in someone
else's thread. That's thread hijacking. So please do not do that.
Independent research is the key to learning. It also saves other
people's times. To start you off here are some links that would help
you:
