How are you running Turbo C, in MSDOS or a virtual PC running MSDOS? Is Turbo C running ok in it's text windowed mode?

yes its working properly i am using windows xp.but does that matter?

according to me a window should be created

You are not trying to create a window (as a window in Microsoft Windows), but to steal a whole screen. Such an approach worked correctly in the old DOS times, but it doesn't work under Windows - unless you will use some kind of DOS emulator.

I'll assume you're doing this in full screen mode (as opposed to windowed mode)? Even so, I'm not sure if all the EGA/VGA bios calls (INT 10H) are emulated in the dos console window for Windows XP. For example, with Windows XP dos console in full screen mode, my old msdos programs are able to load fonts via bios calls, but I'm not able to change the number of lines between 25, 43, or 50 via bios calls.

You could consider using Virtual PC 2007 and installing MSDOS onto it, if you have a copy of MSDOS that you can install. It's a bit of a pain to transfer stuff over to virtual PC. I trasfer files to a cd-rw disc, then copy them from the cd-rw dics in Virtual PC. I haven't tried going the other way. There may be utilities that can transfer to/from a virtual hard drive image, but I haven't tried to look for these.
