How to get handle of MessageBox in order to change font of MessageBox c++ builder : *I'm using c++ builder (bcb6)

I would like change the font of MessageBox. 

I searched over google and find that it's possible to use by WM_SETFONT.

My question is how can I get the handle of the MessageBox?


    HFONT hFont=CreateFont(18,0,0,0,FW_DONTCARE,FALSE,FALSE,FALSE,DEFAULT_CHARSET,OUT_OUTLINE_PRECIS,
                    CLIP_DEFAULT_PRECIS,ANTIALIASED_QUALITY, VARIABLE_PITCH,TEXT("Courier New"));

    MessageBox(NULL,message.c_str(),"Info",MB_OK | MB_ICONINFORMATION);
    SendMessage(??handle of the message box??, WM_SETFONT,(WPARAM) hFont, MAKELPARAM(TRUE, 0));

Any suggestions please?

Your help is very appreciated.
