/*
CCS_BOTTOM
CCS_ADJUSTABLE
CCS_NODIVIDER		Prevents a two-pixel highlight from being drawn at the top of the control. 
CCS_NOHILITE		Prevents a one-pixel highlight from being drawn at the top of the control.
CCS_NOMOVEY			Causes the control to resize
					and move itself horizontally,
					but not vertically, in response
					to a WM_SIZE message.
					If the CCS_NORESIZE style is
					used, this style does not
					apply.
CCS_NOPARENTALIGN	Prevents the control from automatically
					moving to the top or bottom of the
					parent window. Instead, the control
					keeps its position within the parent
					window despite changes to the size
					of the parent window. If the
					CCS_TOP or CCS_BOTTOM style is also
					used, the height is adjusted to the
					default, but the position and
					width remain unchanged. 
CCS_NORESIZE		Prevents the control from using
					the default width and height
					when setting its initial size
					or a new size. Instead, the control
					uses the width and height specified
					in the request for creation
					or sizing. 
CCS_TOP				Causes the control to position
					itself at the top of the parent
					window抯 client area and sets
					the width to be the same as the
					parent window抯 width.
