My problem is that.....
whenever i try to run a graphics program in c on windows vista,it does not since it is not supporting fullscreen mode.
please tell how could i run graphics pro
do i need visual c???

was the C program compiled on Vista, or did you grab an already-compiled .EXE from somewhere else?

you need to have compiled the executable on Vista.

so yes, you'll need a C-compiler. MS provides a basic, free version of Visual C/C++

Dear,the program all tofether was writtwn,compiled,build in vista.
on pressing ctrl+f9
a error screen displays with option ofd close and ignore

then it sounds more like a vista problem and less like a C problem, to me.

i don't use vista, so i can't help you.

maybe someone else knows.

What compiler and graphics library are you talking about?
