texte = >Has anyone done a CAPTCHA system in WebDNA? It's easier (and probably just as effective) to use a system that described a numeric value in words, then just tell the visitor to enter that value in numeric digits: "To stop the robots from submitting this form automatically, please enter 'one two three four five' in numbers into the following form field:" Then just generate the numeric string randomly and use a "numbers to words" database to put the words on the page in between the single quotes. Or instead of individual digits you could use a "numbers to words" database that contains the full verbal description of all the numbers from one to 10,000 and use those verbal descriptions instead: "Please enter the number 'four thousand two hundred seventy nine' into the following form field:" if you use one of these two techniques it can all be done in WebDNA, no images and no other special software required. :) -- Sincerely, Kenneth Grome www.kengrome.com ------------------------------------------------------------- This message is sent to you because you are subscribed to the mailing list
