Free - Usability & security: Unlikely bedfellows?
With an ever increasing online population - 41 million users in the UK alone (source: Internet World Stats) - computer security and user authentication have never been more vital. Unusable security is expensive as well as ineffective. According to Password research, two-thirds of users had to reset their passwords/PINs three or more times in the last 2 years. With each password reset estimated at £35 in help desk costs (source: Mandylion research labs) it's easy to see how expensive an affair this can be.

Free - Have Some Pie!
A couple of weeks ago, I continued writing about the DMXzone charting extension by extending what is already there in the extension to create charts using dynamic data. In the first part, I showed you how to extend the line and sparkline charts to feed from a database and today, I’m going to continue that with pie charts and show you how to create either a 2d or 3d pie chart from dynamic data.
The DMXzone already creates fantastic pie charts using either a visual editor or a datagrid editor where one can enter values and quickly create the chart from those values. Further, the user can export that chart for use in their applications. With dynamic data, however, the chart needs to remain “live” so that changing data can be reflected in the visualization. Since Google charts are created “on the fly” (at runtime) anyway, this Is easily accomplished by simply hooking the code created by the extension up to the database. I gave you an example database in the first part of this article and we can use the same data for the pie chart.
NOTE: This installment was written using the Dreamweaver CS4 beta (available at http://labs.adobe.com) so screenshots may vary a little from Dreamweaver CS3. The DMX Zone Charting extension works in both versions so the user should find very little or no variance in either version of the program.

Creating a Custom WPF ZStackPanel
Recently I found myself in a position whereby I had to create a WPF UserControl of an image viewer. The design for the control looked as if you had taken a stack of images and dropped them down onto a surface. That is, they were not perfectly lined up; some were rotated slightly, some were moved a little to the top, left, bottom or right.
So, I thought about it and decided it would be a good idea to put all of the images into a ListBox Control; however, there was one slight problem: a ListBox Control uses a VirtualizingStackPanel (VSP) to show it content (also known as Children) and a VSP arranges its Children just like a StackPanel; that is, it lines them up one after the other either vertically or horizontally.
