web browser with bing search

Question

Hi guys, im kinda new to c#, so dont get mad when i ask somthing stupid, but ive been working on a web browser for a week now and it has got tabs and controls, but i dont know how to add a search like in ie8 & ie7, so could someone please show me how to get a bing or google search for it? Thanks for your time for reading this message, and im looking forward to your answers. I am using visual studio 2008 pro, if that makes a difference, thanks;)

Answer 1

If you perform a search on IE8 it simply opens a new tab with a address.

Just put a textbox and a button and on button click event open a new tab with an address(samples are below)

It's easy for you to open a new tab if you are developing your own webbrowser.

Here is a sample address for bing and google

http://www.bing.com/search?q=foo&src=IE-SearchBox&FORM=IE8SRC&adlt=strict --> q is the search criteria
http://www.google.com.tr/search?hl=tr&source=hp&q=foo&meta=&aq=f&oq= -->q is the search criteria.

Answer 2

Thankx very much, i appreciate your time and bother to look at a rookie's post, and finally i can go about my search! ;)

Answer 3

could i just have a sample code, please, for the search button? as i dont know what format it is sopposed to be in(how to write it?))

Thankx!

Answer 4

Do you have a method that opens new tab at your browser?

On click event of search button:

Call that method.

string

 

link=String.Format("http://www.bing.com/search?q={0}&src=IE-SearchBox&FORM=IE8SRC&adlt=strict", TextBox1.Text);

get the link variable and open in your new tab.
