I'm trying to make a program that when it runs opens a file on an odd second and then writes to it, but I don't want the DOS like window to pop up when it starts. I figured out one way to prevent this from happening, but I think that it's probably slowing my program down a little. Right now I have it set up like a radc++ program but don't set up any forms. Is there a better way to prevent the window from opening? I'm using Dev C++ 5 and creating this program for a windows machine.
