€30 - €250

Project Description:
PowerPoint 2013 introduces a new application level event Application.AfterShapeSizeChange, see here: [url removed, login to view]
We would like to use this event within a COM add-in written in C# - but not only in PowerPoint 2013 where the event is readily available in the PowerPoint object model, but also for PowerPoint 2007 and PowerPoint 2010.

Unless you have a better idea, it may be worthwile starting with the idea of monitoring registry access (RegQueryValue) to the following registry key:
PowerPoint seems to be querying this registry key every time an object is resized.
Other approaches are also welcome.

- C# / VS 2010 .dll which is loaded as PowerPoint Add-In through a proprietary COM shim
- Pure C# .NET + Windows API / no 3rd party components allowed
- Windows >= Windows XP (32/64bit)
- Office >= Office 2007 (32/64bit)

- C# class incl. source code and documentation
