This is a SketchUp Ruby C++ Extension providing a wrapper around ITaskbarList3 that was introduced to Windows 7.
It is adviced to read up on the interface for how to use it: http://msdn.microsoft.com/en-us/library/windows/desktop/dd391692(v=vs.85).aspx
The Ruby C Extension was created with Visual Studio 2013: http://www.visualstudio.com/downloads/download-visual-studio-vs
NOTE: The Ruby config.h
had to be modified because it was originally intended
for Visual Studio 2010.

require 'taskbar_progress.rb'
model = Sketchup.active_model
entities = model.active_entities
TaskbarProgress.new.each(entities.to_a) { |entity|
entity.erase!
}
