Hello Lenin,
selecting something into a device context doesn't mean that windows will then do any updates automatically. The windows API is not a HLL, you must do everything on your own.
What your code fragments tell me is that you are currently learning both programming in win32 and programming in MASM. This by itself is not easy, but then you shouldn't make things even harder by beginning your efforts with GDI and font stuff, which surely isn't the easiest part of the windows API.
Not to sound rude or ungratefull but I wonder if someone can actually tell me how to correct the problem...
I got tile here:
Do I need to send a WM_SETFONT message? Or what?
