TsgcUDPCLient

TsgcUDPClient implements the UDP Client based on Indy library.

 

UDP is a connectionless protocol where there is no assurance that message sent arrive to the destination but opposite to TCP protocol, it's much faster.

 

1. Drop a TsgcUDPClient component onto the form

 

2. Set Host and Port (default is 80) to connect to an available UDP Server.

    oClient := TsgcUDPClient.Create(nil);
    oClient.Host := '127.0.0.1';
    oClient.Port := 80;

3. You can connect through an HTTP Proxy Server, you need to define proxy properties:

 

    Host: proxy server hostname.

    Port: proxy server port number.

    Username: username for authentication, leave blank for anonymous.

    Password: password for authentication, leave blank for anonymous.

 

4. If you want, you can handle the events

 

5. Call WriteData method to send any message to the UDP server.
