LPRECT qrc,	// pointer to rectangle coordinates
UINT edge,	// type of inner and outer edge to draw
UINT grfFlags	// type of border
);

Parameters
hdc
Identifies the device context.

rc

Points to a RECT structure that contains the logical coordinates of the rectangle.edge
Specifies the type of inner and outer edge to draw. This parameter must be a combination of one inner-border flag and one outer-border flag. The inner-border flags are as follows:

Value	Meaning
BDR_RAISEDINNER	Raised inner edge.
BDR_SUNKENINNER	Sunken inner edge.

The outer-border flags are as follows:

Value	Meaning
BDR_RAISEDOUTER	Raised outer edge.
BDR_SUNKENOUTER	Sunken outer edge.

Alternatively, the edge parameter can specify one of the following flags:

Value	Meaning
EDGE_BUMP	Combination of BDR_RAISEDOUTER and BDR_SUNKENINNER.
EDGE_ETCHED	Combination of BDR_SUNKENOUTER and BDR_RAISEDINNER.
EDGE_RAISED	Combination of BDR_RAISEDOUTER and BDR_RAISEDINNER.
EDGE_SUNKEN	Combination of BDR_SUNKENOUTER and BDR_SUNKENINNER.

grfFlags
Specifies the type of border. This parameter can be a combination of these values:

Value	Meaning
BF_ADJUST	Rectangle to be adjusted to leave space for client area.
BF_BOTTOM	Bottom of border rectangle.
BF_BOTTOMLEFT	Bottom and left side of border rectangle.
BF_BOTTOMRIGHT	Bottom and right side of border rectangle.
BF_DIAGONAL	Diagonal border.
BF_DIAGONAL_ENDBOTTOMLEFT	Diagonal border. The end point is the bottom-left corner of the rectangle; the origin is top-right corner.
BF_DIAGONAL_ENDBOTTOMRIGHT	Diagonal border. The end point is the bottom-right corner of the rectangle; the origin is top-left corner.
BF_DIAGONAL_ENDTOPLEFT	Diagonal border. The end point is the top-left corner of the rectangle; the origin is bottom-right corner.
BF_DIAGONAL_ENDTOPRIGHT	Diagonal border. The end point is the top-right corner of the rectangle; the origin is bottom-left corner.
BF_FLAT	Flat border.
BF_LEFT	Left side of border rectangle.
BF_MIDDLE	Interior of rectangle to be filled.
BF_MONO	One-dimensional border.
BF_RECT	Entire border rectangle.
BF_RIGHT	Right side of border rectangle.
