Search Engines Solution: Google Custom Search Engine

Hello Mr. Jawahar,

Thanks for the previous answer.

Last time you told me about Google Search Engine but there is a little bit confusion regarding this. Taking facility of Google search engine I've seen that there are lots of advertisements pasted on the user's websites as like yours. I just don't want these things on my site. Whatever ad will be it would be mine.
I just want Google search engine facility on my site. Also, one more question. I want to know how to create a javascript code for flashing text. You might have seen these flashing texts on many news channels. It shows like 'Breaking News' appear below the screen.
So, please help me.
