    //  This example requires the Chilkat API to have been previously unlocked.
    //  See Global Unlock Sample for sample code.

    var socket = new chilkat.Socket();

    //  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".

    //  Pretend, for the sake of the example, that the
    //  ficticious server is going to send a "Hello World!" 
    //  after accepting the connection.  
    //  Note: Technically, the ReceiveString may not receive the
    //  complete string, although it's highly probable given the short
    //  length of the "Hello World!" message.
