wxWidgets
Socket
Il progetto che si propone di sviluppare è suddiviso in tre parti:
Una comunicazione tra un server e uno o più client. In questo primo progetto il Server è in grado di inviare messaggi solo all'ultimo client da cui ha ricevuto un pacchetto.
Una gestione di connessioni multiple da parte del server.
In questo progetto il Server memorizza gli indirizzi dei client, quindi può scegliere a chi inviare un messaggio e può riconoscere il client che si disconnette.Un gioco in rete.
Tombola in rete
Avviare un nuovo progetto wxDev-C++ e denominarlo Tombola
L'interfaccia in figura è composta da un wxFlexGridSizer che funge da contenitore per tutti i componenti:
un wxPanel per disegnare la tombola.
un wxMemo per evidenziare le combinazioni vincenti uscite.
un wxButton per estrarre un numero.
un wxStaticTextBox per intitolare la casella sottostante.
un wxButton per mettere il server in ascolto.
un wxListBox per elencare gli utenti connessi.
un wxStaticText per segnalare l'indirizzo IP e la porta di ascolto del server.
un wxEdit per inserire l'indirizzo IP della macchina su cui si esegue l'applicazione.
Al componente frame bisogna abilitare la gestione degli eventi onPaint.
L'applicazione Server.

Avviare un nuovo progetto wxDev-C++ basato su wxWidgets Frame e denominarlo ClientTombola.
sul form sono collocati:
un wxBoxSizer
un wxButton con Label="Chiedi Cartella"
un wxMemo
un wxPanel
un wxEdit

Esercizi
Il server possiede 24 cartelle. Non controlla l'esaurimento delle cartelle disponibili. Non controlla nemmeno il superamento del numero di connessioni.
Un client deve avere la possibilità di comunicare una combinazione vincente.
