Hello! Voici un exemple de la doc de vc. Il permet d'ouvrir un exe sans la fenêtre dos.
----------------------------------------------------------------------
/* EXEC.C illustrates the different versions of exec including:
* _execl _execle _execlp _execlpe
* _execv _execve _execvp _execvpe
*
* Although EXEC.C can exec any program, you can verify how
* different versions handle arguments and environment by
* compiling and specifying the sample program ARGS.C. See
* SPAWN.C for examples of the similar spawn functions.
