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

loSocket = createobject("CkSocket")

// To use a SOCKS4 or SOCKS5 proxy, simply set the following
// properties prior to calling Connect.  The connection may be SSL/TLS or 
// non-secure - both will work with a SOCKS proxy.
// The SOCKS hostname may be a domain name or 
// IP address:
loSocket.SocksHostname = "www.mysocksproxyserver.com"
loSocket.SocksPort = 1080
loSocket.SocksUsername = "myProxyLogin"
loSocket.SocksPassword = "myProxyPassword"
// Set the SOCKS version to 4 or 5 based on the version
// of the SOCKS proxy server:
loSocket.SocksVersion = 5
// Note: SOCKS4 servers only support usernames without passwords.
// SOCKS5 servers support full login/password authentication.

// Connect to port 5555 of 192.168.1.108.
// hostname may be a domain name or IP address.
lcHostname = "192.168.1.108"
llSsl = .F.
lnMaxWaitMillisec = 20000
llSuccess = loSocket.Connect(lcHostname,5555,llSsl,lnMaxWaitMillisec)
if (llSuccess <> .T.) then
    ? loSocket.LastErrorText
    release loSocket
    return
endif

// Set maximum timeouts for reading an writing (in millisec)
loSocket.MaxReadIdleMs = 10000
loSocket.MaxSendIdleMs = 10000

// The server (in this example) is going to send a "Hello World!" 
// message.  Read it:
lcReceivedMsg = loSocket.ReceiveString()
if (loSocket.LastMethodSuccess <> .T.) then
    ? loSocket.LastErrorText
    release loSocket
    return
endif

// Close the connection with the server
// Wait a max of 20 seconds (20000 millsec)
llSuccess = loSocket.Close(20000)
