ajit_gupta,
You have taken
a thread from our FAQ section, converted it to a Microsoft Word file, and posted it in response to a thread that is over 3 years old. Please do not do anything like this again.
First, post a link to a thread, not a Microsoft Word copy of a thread. If we update the list of tutorials in that thread (which happens quite often), your Word Doc continues to have the old links. Most of the regulars here know about the thread. But you will cause them to download your copy because they don't know what it is. Not everyone here is running Windows and can deal easily with A Word file. If everyone did stuff like this, we would run out of disk space.
Second, responding to a very old thread is of questionable value. Nisha was last here in August of 2004. You can find that out by looking at Nisha's profile. And the date of the thread is on the thread itself.
