Syntax
BOOL DrawFocusRect(HDC hDC, const RECT * lprc);
Parameters

[in] Handle to the device context.
lprc
[in] Long pointer to a RECT structure that specifies the logical coordinates of the rectangle.
Return Values

Remarks
Because DrawFocusRect is an XOR function, calling it a second time with the same rectangle removes the rectangle from the screen.
This function draws a rectangle that cannot be scrolled. To scroll an area containing a rectangle drawn by this function, call DrawFocusRect to remove the rectangle from the screen, scroll the area, and then call DrawFocusRect again to draw the rectangle in the new position.
