Question

I am trying to run a MSMQ service for the 1st time.

I have copied an example from MSDN and I am trying to get it to work.

Everything runs OK and there are no errors. Yet when I go to inspect my MSMQ there are no message available/added.

I have used the Trace tool SvcTraceViewe.exe and there are no errors reported.

This is my Service defined in a class DLL:

public class MotionSaver : IMotionSaver
{
    [OperationBehavior]
    public void MotionFrame(byte[] data)
    {
        // DO I NEED TO PUT ANTHING IN HERE??
    }
}

[ServiceContract]
public interface IMotionSaver
{
    //IsOneWay=true denotes that there will no return message from the server to the client.
    [OperationContract(IsOneWay = true)]
    void MotionFrame(byte[] data);
}

This is my Server host which calls the above DLL:

static void Main(string[] args)
{
    try
    {
        using (ServiceHost host = new ServiceHost(typeof(MotionSaver)))
        {
            //Path of the Queue. Here we are creating a private queue with the name VishalQ 
            //where all our message would be stored, if server is unavialable.
            string queueName = ConfigurationManager.AppSettings["queueName"];
            //Checking whether the queue exists or not.
            if (!MessageQueue.Exists(queueName))
            {
                //If the queue doesnot exists it will create a queue with the name VishalQ
                //the second parameter false denotes that the queue would be a non transaction queue. If you want that your queue to be 
                //transaction then make the second parameter to true.
                MessageQueue.Create(queueName, true);
            }
            //finally opening the host to server the clients.
            host.Open();
            Console.WriteLine("Server is up and running on port 32578");
            Console.WriteLine("Press any key to exit");
            Console.ReadKey();
        }
    }
    catch  (Exception ex)
    {
        Console.WriteLine(ex.ToString());
        Console.ReadKey();
    }
}

This is my app.config settings in the host app:

<configuration>
  <appSettings>
    <add key="queueName" value=".\private$\MotionSaverTest4" />
  </appSettings>

  <system.diagnostics>

              initializeData= "SdrConfigExample.e2e" />
        </listeners>
      </source>
    </sources>

This is the client app that call the service:

static void Main(string[] args)
{
    wsMotionQ.MotionSaverClient ws = new MotionSaverClient();
    ws.MotionFrame(new byte[] { 1 });

    Console.WriteLine("All Wishes sent successfully");
    Console.ReadLine();
}

and this is my client app.config:

<configuration>
    <system.serviceModel>
        <bindings>
            <netMsmqBinding>
                <binding name="motionQ">
                    <security mode="None" />
                </binding>
            </netMsmqBinding>
        </bindings>
        <client>
            <endpoint address="net.msmq://localhost/private/MotionSaverTest4"
                binding="netMsmqBinding" bindingConfiguration="motionQ" contract="wsMotionQ.IMotionSaver"
                name="motionQ">
                <identity>
                    <dns value="localhost" />
                </identity>
            </endpoint>
        </client>
    </system.serviceModel>
  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2"/>
  </startup>
</configuration>

I have checked that my message queue has been created.

1). How does a message get added to the queue? What is the point of an empty method in my service? 2). Why are my messages not being added?

Thanks

NB

Changed code to this:

[OperationBehavior]
public void MotionFrame(byte[] jpegData)
{
    using (Message msg = new Message())
    {
        msg.BodyStream = new MemoryStream(jpegData);
        msgQMissedData.Send(msg);
    }
}

You're just creating the queue, but you're not sending / receiving messages to/from it.
