I want to make a Google Search bar in my program, i want it to take the textbox and change that into google's link.

So first put http://www.google.co.uk/search?hl=en&q=
Then change all the spaces to a +
And finally add btnG=Google+Search&meta=

So if i were to type 1 2 3 4

It would give me a string of
http://www.google.co.uk/search?hl=en...G=Search&meta=

Which i could then navigate to. But how do i do this and put all spaces to a +
