Response response = request.Send();

// extract the value from the HTML text 
// <input type="text" name="f_customer" size="32" maxlength="32" value="Joe Smith"> 
string extractedText = response.Extract(
                        cursor,
                        "value=\"",
                        "\"",

WriteMessage(string.Format("The value {0} was found at position {1}", extractedText, cursor.Index));

Response response = request.Send();
