Thread: win32 - how can i change the menu bar font?

i have 1 code that changes the menu bar font:

Code:

CHOOSEFONT cf={0};
LOGFONT *hf=new LOGFONT;
NONCLIENTMETRICS theMetrics;
cf=ShowSelectFont();//show us the dialog font for select the font
            theMetrics.cbSize = sizeof(NONCLIENTMETRICS);

            SystemParametersInfo(SPI_GETNONCLIENTMETRICS,sizeof(NONCLIENTMETRICS),
                            (PVOID) &theMetrics,0);
       
            theMetrics.lfMenuFont=*cf.lpLogFont;
            SystemParametersInfo(SPI_SETNONCLIENTMETRICS,sizeof(NONCLIENTMETRICS),
                            (PVOID) &theMetrics,0);

the menu bar font is changed, but not only on my application window. but on entire OS.
can anyone advice me more?
(in these situation, i don't want use OWNERDRAW)
