SharePoint CAPTCHA

Posted by: Toni Frankola In: SharePoint

When working on a project that includes SharePoint in Internet facing scenario, your customer might request a CAPTCHA or some similar anti-spam algorithm to prevent automated postings to blogs and wikis.

I found a nice .NET component developed by LanapSoft. It includes some cool features like 50 different CAPTCHA algorithms and sound support. You can find the details on how to create a SharePoint web part with it here: SharePoint Captcha.

Hi,
Does the Captcha from LANAP require that the user hit the submit button? I would like to add a captcha to a normal sharepoint submit form. when i click the submit button i want the captcha to automatically fire. just like on your blog. but how do you connect that Lanap web part to the sharePoint list submit event?
