Voglio che la mia applicazione, quando da riga di comando del prompt DOS scrivo
Miaapp.exe Come Va?
mi risponda scrivendo sempre nel prompt del DOS:
“bene”
Sono riuscita in parte a fare ciò che volevo usando l’esempio di codice che ho trovato nella API GUIDE:
solo che il messaggio me lo scrive aprendomi una nuova console; io voglio che me lo scriva nella console attuale.
