Creare tipo di file (era: Aprire un exe con doppio click)

[Princex]

Ciao a tutti.
Volevo chiedervi se qualcuno sa come creare un file in visual basic 6 con un estensione personalizzata che permetterà all'utente di aprire il programma con riferimento il nome di questo file.


in poche parole
es: .txt apre il blocco note con il documento .txt
.prn apre il mio programma con il path del documento .prn


Grazie per l'aiuto
