Receive a Bounded String from a Socket

See more Socket/SSL/TLS Examples

Demonstrates Socket.ReceiveStringMaxN, which receives and decodes text like ReceiveString but reads at most a given number of input bytes.

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 and decode text like ReceiveString, but read at most the given number of input bytes.
'  The limit is measured in bytes, not Unicode characters.
Dim firstChunk As String = socket.ReceiveStringMaxN(64)
If (socket.LastMethodSuccess = False) Then
    Debug.WriteLine(socket.LastErrorText)
    Exit Sub
End If

Debug.WriteLine(firstChunk)
