0	Captcha code is a kind of image in which text are written that can only be read by human not by robots (a kind of program that automatically submit data to the websites). Eg. there might be wired background and text might be written in different angles. This helps the validate that the user who is going to interact (or submit data to the website) is not robots but it is actual human being. That is why at the time of submission of data you are shown an image and asked to write the text displayed in the image into the textbox, if the text in the image and textbox text are same, it is assumed that you are human otherwise some kind of robots and you are not allowed to submit the data. This is a kind of security to your website as you are not allowing robots to play with your website content. Hope this helps. thanks Regards, Sheo Narayan http://www.dotnetfunda.com Madhuri123, if this helps please login to Mark As Answer. \| Alert Moderator
