Bonjour,
Ce code est certe un peu crade (j'ai fait ça vite fait pour vérifier que ça marche)

J'ai simplement fait Fichier/Nouveau/Projet...
Puis Windows Application dans l'onglet Basic
J'ai enfin ajouter 3 bouts de code pour illustrer ton problème.
A NOTER : il faut impérativement que le programme notepad.exe se trouve sous c:\windows, sinon ça ne marche pas.
