The article below has a minor improvement to the previous article listed on this web site. Specifically, the previous article used the DropDownList as a mechanism to actually retrieve the data for the purposes of storing it in a local Dictionary. This article simply calls the ObjectDataSource directly to retrieve an IEnumerable type and iterates over that. Below is article with the updates.

In this article we will demonstrate a technique used to automatically add Wiki Pages to PBWiki using the not quite released API provided by the peanut butter guys. The demonstration will involve integrating scheduled presentations at our Silicon Valley Code Camp on October 7th and 8th each with its own Wiki Page. Without the API, creating and linking the presentation to a Wiki page would have to be an ugly manual process involving the dreaded cut and pasting of URL’s.

It’s Monday, August 21st, we have our CodeCamp scheduled for October 7th and 8th in Los Altos California and we realize we need to have our web site to sign up and running yesterday! For those of you who don’t know what a codecamp is, basically, it’s a developer to developer weekend meeting where high quality presentations are given to an audience of enthusiastic developers. Typically, 30 or 40 speakers running simultanious presentations to 300 or so attendees. Codecamps are all Volunteer, all free, and always on a weekend. So, our web site needs to allow sign ups for speakers and their presentations, attendess to let us know they are coming, provide information about the Venue as well as ultimately provide scheduling information about classes. Most importantly, it needs to do it with style and pizazz. Sunday 20 August 2006 @ 7:26 pm
In this article, the basic usage of a CAPTCHA custom server control will be discussed. This control is for use in ASP.NET 2.0 only. It is provided in source as well as executable form which means you can use it in your app_code or bin directly. If you use the DLL version, it will support drag and drop from the Visual Studio 2005 Toolbox. The control supports templates which means you can customize it to work in your application giving a consistent look and feel. Below are two representations of the use of the CAPTCHA custom server control. One is simply using the control in it’s default configuration with no template, and the other is after modifying the controls template with extra contact information.
