Thank you Aurick for removing unrelated and negative posts to bring my relevant thread back that contains informative and articles to review of few attempts to find solution.
And second thank you for creating forum a friendly environment for who can freely express within respectful boundary. I have said few wrong words and I will try my hardest to eliminate that.
