Now 3 things I would like to convey you about Code Project here:
1. Don't write something like:"Pls reply me as soon possible" - It looks rude and people here help at their convenience.
2. Don't use text speak. Use full words. It does not look professional.
3. If an answer helps you and resolves your doubt, make a habit of making it as Accepted Answer.
