Search toolbar in IE

Hi all!

I need to create an installable application that adds a custom search toolbar in Internet Explorer. When a user does a search using this, it will search a specific site.

Does anyone know how to do this? The perfect thing would be that someone had full code for this.

Help will be GREATLY appreciated!!!!

Thanks.

if you are looking for sample then
try Google toolbar check out its behaviour.

and could you specify more details plz.
