Close a Socket Connection

See more Socket/SSL/TLS Examples

Demonstrates Socket.Close, which gracefully terminates and closes the current TCP, TLS, or SSH channel connection. The argument bounds how long to wait for clean shutdown processing.

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"

'  Gracefully close the current TCP, TLS, or SSH channel connection.  The argument is the maximum
'  number of milliseconds to wait for clean shutdown processing (0 waits indefinitely).
success = socket.Close(1000)
If (success = False) Then
    Debug.WriteLine(socket.LastErrorText)
    Exit Sub
End If

Debug.WriteLine("Connection closed.")
