	Date :			2004-05-07

	Purpose :		This class encapsulates a toolbar that can be used with 
					"CRulerRichEditCtrl". The class is derived from "CToolBarCtrl", 
					and manages a formatting toolbar

	Description :	A "CToolBarCtrl"-derived class. Reads a toolbar resource 
					with the ID "TOOLBAR_CONTROL" and adds combo controls for 
					font name and -size, as well as a color picker at the 
					positions "FONT_NAME_POS", "FONT_SIZE_POS" and 
					"FONT_COLOR_POS" respectively.

	Usage :			Created by the rich edit mini-editor.
