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

$socket = New-Object Chilkat.Socket

# To connect through an HTTP proxy, set the HttpProxyHostname
# and HttpProxyPort properties to the hostname (or IP address)
# and port of the HTTP proxy.  Typical port numbers used by
# HTTP proxy servers are 3128 and 8080.
$socket.HttpProxyHostname = "www.my-http-proxy.com"
$socket.HttpProxyPort = 3128

# Important:  Your HTTP proxy server must allow non-HTTP
# traffic to pass.  Otherwise this does not work.

# Connect (via the HTTP proxy) to port 5555 of 192.168.1.108.
# hostname may be a domain name or IP address.
$hostname = "192.168.1.108"
$ssl = $false
$maxWaitMillisec = 20000
$success = $socket.Connect($hostname,5555,$ssl,$maxWaitMillisec)
if ($success -ne $true) {
    $($socket.LastErrorText)
    exit
}

# Set maximum timeouts for reading an writing (in millisec)
$socket.MaxReadIdleMs = 10000
$socket.MaxSendIdleMs = 10000

# The ficticious server (in this example) is going to send a "Hello World!" 
# message.  Read it:
$receivedMsg = $socket.ReceiveString()
if ($socket.LastMethodSuccess -ne $true) {
    $($socket.LastErrorText)
    exit
}

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