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

Dim success As Boolean
success = socket.UnlockComponent("Anything for 30-day trial")
If (success <> True) Then
    Debug.Print socket.LastErrorText
    Exit Sub
End If

Dim ssl As Boolean
ssl = True
Dim maxWaitMillisec As Long
maxWaitMillisec = 20000

'  The SSL server hostname may be an IP address, a domain name,
'  or "localhost".  You'll need to change this:
Dim sslServerHost As String
sslServerHost = "123.123.88.88"
Dim sslServerPort As Long
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:
Dim receivedMsg As String
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
