Dim listenSocket As New Chilkat.Socket // Pass a value of 0 for the port number to randomly select // an unused port. // (The 2nd argument allows for a backlog of 25 pending connection requests when accepting connections.) Dim success As Boolean success = listenSocket.BindAndListen(5555,25) If (success <> True) Then System.DebugLog(listenSocket.LastErrorText) Return End If // Find out what port was chosen. // Note: The ListenPort propety was added in Chilkat v9.5.0.59 Dim listenPort As Int32 listenPort = listenSocket.ListenPort System.DebugLog("Chosen listen port = " + Str(listenPort)) |
