This control provides a calendar control class for displaying and selecting dates.  In addition, the class is extended and can now be used for printing/previewing.

Additional features include weekend highlighting and business type Monday-Sunday format.

See example for various methods used to set display month, year, and highlighted dates (different font and background colours).
