Does anyone know where I can find a good and easy to understand sample or
tutorial of captcha validation for asp.net? (with source code not something
like recaptcha)
the ones I found are too complicated to implement

thanks,
Tem

Search on "ASP.NET Captcha control" and include the quotes.
An excellent Captcha that won't strain your eyes or frustrate you is simply
to ask the user to enter the sum of two displayed numbers. Even simpler, Jeff
Attwood displays a graphic with the word "Orange" which never changes, and
states that it is near 100% effective.
