Response response = request.Send();

// extract the value from the HTML text, defaulting to "Joe Jones" if the value cannot be found 
// <input type="text" name="f_customer" size="32" maxlength="32" value="Joe Smith"> 
string extractedText = response.Extract(
                        "value=\"",
                        "\"",
