multithreading - what is the best multi-threading technique in c# -

-

I am developing an application that is running a lot of TcpListener functions, with C #.

  1. Listening to getting an xml message
  2. Read an ID from Li> A special camera based on ID takes snapshot and stores it in the folder

    This is to run within 1 second, so I can take a snapshot with the camera. Using the following code, I have been delayed in executing this task: 

      private threads listen_thread; Public zero start_listen () {this.listen_thread = new thread (new threadstart (save_data)); This.listen_thread.Priority = ThreadPriority.Normal; This.listen_thread.Start (); } Private Zero save_data () {// work done}   
     Is this the best multi-threading technique to use? This app is running on the Dell Powerz 2900 with 2 quad-core professors, and I think it can be fast, how can I be able to improve the latency of this code?  
     Code for TCListener  
      Int32 port = controller_port; Try {// this server IP IP address LocalADR = IPADressesPers (IIP); Server = new TCPListener (localader, port); Server.Start (); Byte [] bytes = new byte [256]; String data = null; While (true) {Console.Write ("Waiting for connection ..."); TcpClient Client = server.AcceptTcpClient (); Console.Write ("Connected!"); Data = null; NetworkStream stream = client.GetStream (); Int i; String add_data = ""; Console.Write ("Waiting ...!"); While ((i = stream read. (Byte, 0, bytes lang)) = 0) {try {string full_row = ""; Data = System.Text.Encoding.ASCII.GetString (bytes, 0, I); Console Type ("Received from Admin:" + Data); Add_data + = data; } Hold {}}}}   
     Then I divide it to get the ID.

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.

Python's equivalent for Ruby's define_method? -

What is a Python equivalent for Ruby's define_method , which is the dynamic generation of class methods will allow? (As can be seen in Wikipedia) Functions are first-class objects in Python and assign them The properties of a class or an example can be a way of doing the same thing as a Wikipedia example: colors = {"black": "000", "red": "F00", "green": "0f0", "yellow": "ff0", "blue": "00f", "magenta": "fff", "cyan": "0ff", "white": " FFF "} Class MyStream (ARR): Pass for Name, Code in colors.iteritems (): def _in_colour ( W code = code): return '& lt; Span style = "color:% s" & gt;% s & lt; / Span & gt; ' % (Code, self) setter (histrive, "in_" + name, _in_ color)
