Receive a String from a Socket

See more Socket/SSL/TLS Examples

Demonstrates Socket.ReceiveString, which receives text and decodes it using StringCharset. It returns the first nonempty decoded result rather than draining all available data.

Dim success As Boolean = False

Dim socket As New Chilkat.Socket

'  Connect to the server using TLS.  The 3rd argument enables the TLS handshake after the TCP
'  connection succeeds; the 4th is the maximum time to wait, in milliseconds.
Dim bTls As Boolean = True
Dim maxWaitMs As Integer = 5000
success = socket.Connect("example.com",5000,bTls,maxWaitMs)
If (success = False) Then
    Debug.WriteLine(socket.LastErrorText)
    Exit Sub
End If


'  StringCharset controls the character encoding used when sending and receiving text.
socket.StringCharset = "utf-8"
'  Send a request using a simple application-defined text protocol in which each message ends with a
'  CRLF.
Dim command As String = "STATUS" & vbCrLf
success = socket.SendString(command)
If (success = False) Then
    Debug.WriteLine(socket.LastErrorText)
    Exit Sub
End If


'  Receive text and decode it using StringCharset.  ReceiveString returns the first nonempty decoded
'  result; it does not keep reading to drain all available data.
Dim responseText As String = socket.ReceiveString()
If (socket.LastMethodSuccess = False) Then
    Debug.WriteLine(socket.LastErrorText)
    Exit Sub
End If

Debug.WriteLine(responseText)
