MSDN® is sponsoring a coding contest for Office 2007, named OfficePalooza! This sweepstakes will run two weeks beginning April 20, 2009, and features ten fun Visual Basic of Applications™ (VBA) coding challenges in the form of puzzles and games. Each entrant will earn a chance to win one of hundreds of available prizes, determined by a random drawing at the end of the contest.
In conjunction with this contest, an Advanced Business User theme will run on Microsoft Office Online from mid-April to mid-May, and will showcase the automation and extensibility aspects of Office 2007 through macros, custom VBA coding, the Fluent UI, and Office Open XML. This collaborative effort will also highlight existing and newly-created content on the MSDN Microsoft Office Developer Center.
There are a few Access challenges which could be interesting.
