6. TCP 之Client/Server的應用
設定 TServerSocket 的屬性
Server->Active; 啟動等待
Socket->ReceiveText(); 接收資料
設定 Event
OnAccept (接受Client 的連接)
OnClientConnect (連自Client 的連接要求)
OnClientDisconnect (Client中斷連結)
OnClientRead (讀取Client 端傳送資料)
OnListen (Server 等待事件)

7. TCP 之Client/Server的應用(cont.)
設定 TClientSocket 的屬性
Client->Active = true; 啟動連結
Client->Socket->SendText(“ABC”); 傳送字串
設定 Event
OnConnect (連結中的事件)
OnConnecting (嘗試連結的事件)
OnDisconnect (連結中斷)

8. Windows Processing Design結論
利用 TClientSocket 與 TserverSocket 來設計一個簡單的Client/Server 架構
