Anybody had experience on how to do CAPTCHA here in xojo?

I wrote this as a test for the Web Edition when it was first released. I haven’t touched it since then and there may be issues with using it in newer editions of the IDE, but it should give you some ideas at least.

Please no Captchas!!! Why not using simple signatures?
(form only works if not signed)

I don’t understand what you mean by signature.

Thanks to Andrew Lambert!

He is the one!

you have to sign the form with your handwritten (mousewritten) signature

For web edition I built google’s ReCaptcha into a control

I don’t see how a signature would be secure. A computer could simulate a signature, it’s harder for the computer to solve a captcha.
