This control has no business value at all. It only gets the Daily Dilbert strip from the current date and displays the image in your XPages application.
Technically it uses an XML stream as input and gets the current days picture from the stream.
Just copy the custom control to your application, sign the design element and drag it from the list of customcontrols to your XPage. There are no parameters to set
Update: Sunday 29-May-2011
Added a new custom control to the project to navigate thru the strips.
