(Visual Basic 6.0) 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.

Dim socket As New ChilkatSocket

' 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:
socket.SocksHostname = "www.mysocksproxyserver.com"
socket.SocksPort = 1080
socket.SocksUsername = "myProxyLogin"
socket.SocksPassword = "myProxyPassword"
' Set the SOCKS version to 4 or 5 based on the version
' of the SOCKS proxy server:
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.
Dim hostname As String
hostname = "192.168.1.108"
Dim ssl As Long
ssl = 0
Dim maxWaitMillisec As Long
maxWaitMillisec = 20000
Dim success As Long
success = socket.Connect(hostname,5555,ssl,maxWaitMillisec)
If (success <> 1) Then
    Debug.Print socket.LastErrorText
    Exit Sub
End If

' 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:
Dim receivedMsg As String
receivedMsg = socket.ReceiveString()
If (socket.LastMethodSuccess <> 1) Then
    Debug.Print socket.LastErrorText
    Exit Sub
End If

' Close the connection with the server
' Wait a max of 20 seconds (20000 millsec)
success = socket.Close(20000)

Debug.Print receivedMsg
