c# - Cross client GUI update -


This is my simplified scenario, each client has a PC on LAN: 

  Customer 1: Add Maximum Number: _ Maximum Number: 0   
 
  Client 2: Add Max Number: Maximum Number: 0   < hr> 
 then saves " 1 " as the maximum number of  Customer 1  and  Client 2  will automatically update and receive changes To:  
 
  Customer 2: Add maximum number : _Maximum number: 1 (last updated on 23/04/2014 by Client 1)    
 
 
 1-Voting: DB servers in regular intervals for each user's update:       
 itemprop = "text" Asking:  
  Pros: Easy to implement, safe cons: excessive bandwidth and consumption of DB server process   
 2-centralized TCP server: A dedicated machine Listens to the connection, each client connects to it and informs events, the server redirects those events to the related client.  
  Pros: Minimum bandwidth, not necessarily much process is needed: more   
 3-decentralized UDP notification: If the clients are in the same LAN, You can broadcast UDP packets in that network, each customer will receive every notification sent by any client.  
  Pros: Minimum bandwidth, 0 process requirement, no need of central server Cons: It is not guaranteed that the packet reaches it (but usually a close lane they do).   
 So, these are the most common ways to do this, now you have to balance your needs and choose one.  
 In your case, I will try the UDP, if you need to ensure packet reception, then your clients can wait for the response of an event and if they react to X If not found then broadcast the packet again, thus you will ensure the reception.

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

java - JPA TypedQuery: Parameter value element did not match expected type -

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
