How to change the width of the title bar

Method 1:

Nonclientmetrics NCM;
NCM. cbsize = sizeof (nonclientmetrics );

: Systemparametersinfo (spi_getnonclientmetrics,
Sizeof (nonclientmetrics ),
& NCM,
0
);

NCM. lfcaptionfont. lfheight =-300;
: Systemparametersinfo (spi_setnonclientmetrics,
Sizeof (nonclientmetrics ),
& NCM,
Spif_sendchange
);

Method 2:

Case wm_nccalcsize:
{
Bool bspecial = false;
Int nedgewidth = 3;
Int nbarheight = captionheight + 3;
Int nbottomedge = 3;

If (! (Bool) wparam)

Copyrect (& rtsave, (lprect) lparam );
//: Callwindowproca (lpwndinfo-> pwndproc, hwnd, umsg, wparam, lparam );

{

}
