An extensive and clear article about captcha. I was having trouble with my blog's captcha source code, it looked simple at first but then I made a mess. This is the best blog I've found, it solved all my doubts and more. Finally! An extensive and clear article about captcha.

I searched the entire web but found this one honest example with less talk and more code. Pushing my luck a little further. When the Login Control --> Convert to Template is done the Web Controls has the data bindings like '<%# DataBinder.Eval(..." and so on in the HTML. Same thing when a Datagrid BoundColumn is converted to a TemplateColumn. The databinding text remains. HOW DO I ACHIEVE THAT. I will check this website for a couple of days for a reply. An email notification when replied would be highly appreciated. This article was of tremendous help.

I have verified the httpHandlers web config lines and they are identical as you have in your article. I am using Jeremy Wadsworth's code and I have not changed anything but some parameters values to test what they do. Then I changed them back to their original state. I am very new at all this (asp, VB, etc..) I do not know where to look. I am using Jeremy's code under aspnet 3.5 in Godaddy. I am not sure if I have (or need) write privileges in the host. I understand the image is saved in cache. Do I need to set something to allow this? As a reminder, when the page loads (not logged in), everything comes up (the recalculate button, the promo link) but the captcha image. When I load the View Code page, I see that the imageUrl has changed and have something like “CaptchaType.ashx?id=” and a long number id. Hope you can help/ Thanks Hello Peter, its me again.

Just wanted to report what seems to be a bug: When nothing is entered in the TextBox that holds the CAPTCHA characters an exception is thrown in CaptImageUtils.cs:132 the variable cp has the value null. As long as the textbox isn't empty when a postback occurs it works fine, so I just worked around it by letting the user know via javascript to enter something in the field.
