One of the most appreciable changes in the task panel of
Windows 7 is the possibility to display progress of a task execution (progress
bar) in the task panel directly.

In this figure it is seen very well, that on the task panel
the information about copying process is displayed. Such functionality is realized
in Windows 7 for files copying, data from a network downloading (Internet
Explorer) and in other applications. This functionality can be used and for
your own applications. A lot of scenarios can be - displaying of data
transformation process, copying, formations of data, construction of reports,
generation of images, etc.
WindowsFormsExtensions сlass contains two methods
which should take place in this case: SetTaskbarProgress and
SetTaskbarProgressState. The call of the first method allows us to specify the
percent of a current task execution.
Listing 1: Setting values for progress bar of task
panel of Windows 7
WindowsFormsExtensions.SetTaskbarProgress(this, 35);
SetTaskbarProgressState method which allows us to set a
current state of a progress-bar.
Listing 2: Setting state for progress bar
WindowsFormsExtensions.SetTaskbarProgressState(this,
Windows7Taskbar.ThumbnailProgressState.Normal);
There are four available modes: Normal, Indeterminate, Error
(displayed by a red color) and Paused (displayed by a yellow color).
