(PowerBuilder) Socket/SSL/TLS through SOCKS5 / SOCKS4 Proxy

Demonstrates how to use the Chilkat Socket/SSL/TLS component/library with a SOCKS5 or SOCKS4 proxy server.

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

loo_Socket = create oleobject
// Use "Chilkat_9_5_0.Socket" for versions of Chilkat < 10.0.0
li_rc = loo_Socket.ConnectToNewObject("Chilkat.Socket")
if li_rc < 0 then
    destroy loo_Socket
    MessageBox("Error","Connecting to COM object failed")
    return
end if

// 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:
loo_Socket.SocksHostname = "www.mysocksproxyserver.com"
loo_Socket.SocksPort = 1080
loo_Socket.SocksUsername = "myProxyLogin"
loo_Socket.SocksPassword = "myProxyPassword"
// Set the SOCKS version to 4 or 5 based on the version
// of the SOCKS proxy server:
loo_Socket.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.
ls_Hostname = "192.168.1.108"
li_Ssl = 0
li_MaxWaitMillisec = 20000
li_Success = loo_Socket.Connect(ls_Hostname,5555,li_Ssl,li_MaxWaitMillisec)
if li_Success <> 1 then
    Write-Debug loo_Socket.LastErrorText
    destroy loo_Socket
    return
end if

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

// The server (in this example) is going to send a "Hello World!" 
// message.  Read it:
ls_ReceivedMsg = loo_Socket.ReceiveString()
if loo_Socket.LastMethodSuccess <> 1 then
    Write-Debug loo_Socket.LastErrorText
    destroy loo_Socket
    return
end if

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