TCP/IP Socket Connect to Remote Host:PortDemonstrates how to create a TCP/IP socket, connect to a remote host:port, and receive a "Hello World!" message.
Chilkat.Socket socket = new Chilkat.Socket(); bool success; success = socket.UnlockComponent("Anything for 30-day trial"); if (success != true) { MessageBox.Show("Failed to unlock component"); return; } // Connect to port 5555 of localhost. // The string "localhost" is for testing on a single computer. // It would typically be replaced with an IP hostname, such // as "www.chilkatsoft.com". bool ssl; ssl = false; int maxWaitMillisec; maxWaitMillisec = 20000; success = socket.Connect("localhost",5555,ssl,maxWaitMillisec); if (success != true) { MessageBox.Show(socket.LastErrorText); return; } // Set maximum timeouts for reading an writing (in millisec) socket.MaxReadIdleMs = 10000; socket.MaxSendIdleMs = 10000; // The server (in this example) is going to send a "Hello World!" // message. Read it: string receivedMsg; receivedMsg = socket.ReceiveString(); if (receivedMsg == null ) { MessageBox.Show(socket.LastErrorText); return; } // Close the connection with the server // Wait a max of 20 seconds (20000 millsec) socket.Close(20000); MessageBox.Show(receivedMsg); |
