Thanks for your reply ...
Actually, I have decided not to come to thi forum again! These people are too much concerned about their forum security and don't value my need of the time ...
They simply post the topic so late that I can find answers on other forums before they list my topic on this forum. This is the worst forum I have ever seen and does not carry any sense to be alive in the Online Programmers' Discussion Community. This forum has to be removed from Internet.
