Metro Messaging

Here is a Metro styled client/server application that sends messages via queues:

Queuing Frameworks

 

Other Frameworks

Other Concepts

• Real time updating Metro style Tiles as messages are received
• Custom user control with data binding including dependency properties
• Value converter as mark up extension (no need to reference as a resource)
• Auto scrolling textboxes using custom attached property
• Generics with predicates
• MVVM Light locator, messenger, relay commands and view models
• Metro style app with Elysium and Metro Icons (http://metro.windowswiki.info/)
• Custom Build Event:    copy $(SolutionDir)Libs\zeromq\libzmq.dll $(TargetDir)

Deployment

You’ll need to install the server components for MSMQ and RabbitMQ before running the solution from the downloadable source below.

ØMQ (Zero MQ)

ZeroMQ is a socket library that allows developers to create distributed, concurrent, queue based messaging systems with high availability.  One of the many benefits is the abstraction of dealing with sockets at a queue and atomic message level.

It’s really simple to use, here is an example:

Client

namespace Client
{
    using System;
    using System.Text;

    class Program
    {
        static void Main()
        {
            using (var ctx = new ZMQ.Context(1))
            {
                var socket = ctx.Socket(ZMQ.REQ);
                socket.Connect("tcp://localhost:5555");

                while (true)
                {
                    socket.Send(Encoding.ASCII.GetBytes("Hello"));

                    byte[] message;
                    socket.Recv(out message);

                    Console.WriteLine(Encoding.ASCII.GetString(message));
                }
            }
        }
    }
}

Server

namespace Server
{
    using System;
    using System.Text;

    class Program
    {
        static void Main()
        {
            using (var ctx = new ZMQ.Context(1))
            {
                var socket = ctx.Socket(ZMQ.REP);
                socket.Bind("tcp://*:5555");

                while (true)
                {
                    byte[] message;
                    socket.Recv(out message);

                    Console.WriteLine(Encoding.ASCII.GetString(message));

                    socket.Send(Encoding.ASCII.GetBytes("World"));
                }
            }
        }
    }
}
