Scanner d'ip
Contenu du snippet
Voici ma toute première source en Csharp, enfin !!! Bon ceci est un simple scanner multithread avec une interface graphique. A mon avis g fait un travail barbar malgrès que j'ai essayé de reprendre la structure que j'ai vu dans d'autre programme. Je m'attend bien sur à de nombreuses critiques...
Ce que j'aurai aimé faire c'est une seconde list avec les ip en cours de scan.
Je pensé pour de remplacer
//Console.WriteLine("{1}\t***Connection to {0}\n",ip,n);
par
listBox2.Items.Add(ip);
Mais je me suis rendu compte que le résultat ne s'affiché k la fin du scan et non au fur et à mesure. Faut que je trouve pkoi et si qlq1 pouvais m'aidé ce serai plus simple !!
Have fun
