Receive Text up to a Delimiter Byte

See more Socket/SSL/TLS Examples

Demonstrates Socket.ReceiveStringUntilByte, which receives bytes until a specific raw byte value is found, then decodes the preceding bytes using StringCharset. The delimiter is excluded from the returned string.

Dim success As Long
success = 0

Dim socket As New ChilkatSocket

'  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 Long
bTls = 1
Dim maxWaitMs As Long
maxWaitMs = 5000
success = socket.Connect("example.com",5000,bTls,maxWaitMs)
If (success = 0) Then
    Debug.Print 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
command = "STATUS" & vbCrLf
success = socket.SendString(command)
If (success = 0) Then
    Debug.Print socket.LastErrorText
    Exit Sub
End If

'  Receive bytes until a specific raw byte value is found, then decode the preceding bytes using
'  StringCharset.  The delimiter itself is excluded from the returned string.  Here the delimiter is
'  the linefeed byte (decimal 10).
Dim line As String
line = socket.ReceiveStringUntilByte(10)
If (socket.LastMethodSuccess = 0) Then
    Debug.Print socket.LastErrorText
    Exit Sub
End If

Debug.Print line
