The DrawFocusRect function draws a rectangle in the style used to indicate that the rectangle has the focus.
BOOL DrawFocusRect(
HDC hDC, // handle to device context
CONST RECT *lprc // pointer to structure for rectangle
);
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero.
Windows NT: To get extended error information, call GetLastError.
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.
