## Class TCaptchaValidator

Description

TCaptchaValidator class

TCaptchaValidator validates user input against a CAPTCHA represented by a TCaptcha control. The input control fails validation if its value is not the same as the token displayed in CAPTCHA. Note, if the user does not enter any thing, it is still considered as failing the validation.

To use TCaptchaValidator, specify the ControlToValidate to be the ID path of the input control (usually a TTextBox control}. Also specify the CaptchaControl to be the ID path of the CAPTCHA control that the user input should be compared with.
