Receive Text up to a Match into a StringBuilder

See more Socket/SSL/TLS Examples

Demonstrates Socket.ReceiveUntilMatchSb, which receives bytes until an exact byte sequence is found and appends the received text to a StringBuilder.

Dim success As Boolean
success = 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
bTls = True
Dim maxWaitMs As Int32
maxWaitMs = 5000
success = socket.Connect("example.com",5000,bTls,maxWaitMs)
If (success = False) Then
    System.DebugLog(socket.LastErrorText)
    Return
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" + EndOfLine.Windows
success = socket.SendString(command)
If (success = False) Then
    System.DebugLog(socket.LastErrorText)
    Return
End If

//  Receive bytes until an exact byte sequence is found, appending the received text to a
//  StringBuilder.  The match may span multiple underlying network reads.
Dim sb As New Chilkat.StringBuilder
success = socket.ReceiveUntilMatchSb("<EOM>",sb)
If (success = False) Then
    System.DebugLog(socket.LastErrorText)
    Return
End If

Dim response As String
response = sb.GetAsString()
If (sb.LastMethodSuccess = False) Then
    System.DebugLog(sb.LastErrorText)
    Return
End If

System.DebugLog(response)
