static unsigned long start_time = 0;
static unsigned long end_taken = 0;
static int FPS = 0;

//start loop

start_time = GetTickCount();
// do your fancy code here

end_time = GetTickCount();
FPS = 1000/(end_time - start_time);

//end loop

GetTickCount() works with resolution of 1/1000th second under win32. I think GetTickCount() is accurate to < 10ms on most win OS's.
