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

Dim socket As Chilkat.Socket
Set socket = Chilkat.NewSocket


ssl = True

maxWaitMillisec = 20000

' The SSL server hostname may be an IP address, a domain name,
' or "localhost".  You'll need to change this:

sslServerHost = "123.123.88.88"

sslServerPort = 8123

' Connect to the SSL server:

success = socket.Connect(sslServerHost,sslServerPort,ssl,maxWaitMillisec)
If (success <> True) Then
    Debug.Print socket.LastErrorText
    Exit Sub
End If

' Set maximum timeouts for reading an writing (in millisec)
socket.MaxReadIdleMs = 20000
socket.MaxSendIdleMs = 20000

' Send a "Hello Server! -EOM-" message:
success = socket.SendString("Hello Server! -EOM-")
If (success <> True) Then
    Debug.Print socket.LastErrorText
    Exit Sub
End If

' The server (in this example) is going to send a "Hello Client! -EOM-" 
' message.  Read it:

receivedMsg = socket.ReceiveUntilMatch("-EOM-")
If (socket.LastMethodSuccess <> True) 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
