void FrameRect( LPRECT lpRect, CBrush* pBrush );
lpRect
Points to a RECT or CRect that contains the logical coordinates of the upper-left and lower-right corners of the rectangle. You can also pass a CRect object for this parameter.
pBrush
Identifies the brush to be used for framing the rectangle.
Draws a border around the rectangle specified by lpRect. The function uses the given brush to draw the border. The width and height of the border is always one logical unit.
If the rectangle's bottom coordinate is less than or equal to top, or if right is less than or equal to left, the rectangle is not drawn.
