Here is how you can translate a Text using Google's "Unofficial" API's.
The URL for Google Translate is - http://www.google.com/translate_ ... =UTF8&text={0}&langpair={1}
- Y# g6 k2 n! E1 ?( h' Y8 M' L) |) C

[li]"text" is your input string which needs to be translated. [/li][li]langpair is the language pairs involved in the tranlsation. E.g. "ar|en" means translate from Arabic to English.[/li]

The result when you browse to the URL is a HTML page. You will have to do screen scraping to get your translated text.
