I'm trying to find a way to process messages in the order they were sent from the sender since NServiceBus does not guarantee that messages will be processed in a particular order. The sender is an order system which publishes createOrder and reviseOrder commands. The sender allows the user to submit multiple revisions to the same order so there can be revision 4 and revision 3 in the queue at the same time. Each revision has a revision number and reason code associated with it which drives some business logic so we cannot ignore any revisions or at least the reason part of it. A couple of

I've set up a simple test comprising a publisher with two subscribers, all running on a single machine using MSMQ and MassTransit (2.1.1) RuntimeServices which is using a local Sql Server database. I've included the Bus set up code below so you can see what's set up. I'm starting each component manually and independently to try to workout what happens if a subscriber ins't running. I ran the two subscribers first so the queues and subscriptions are all set up and then quit them both, without unsubscribing from the messages. If I then run the publisher on its own, which dumps 400 messages in

I've created a WCF service that listens to a private MSMQ for jobs. I've throttled my service so that it will only handle one job at a time (maxConcurrentInstances = 1). The problem I have is that when two messages are submitted and I inspect the queue through my Computer Management console, it's empty. I expect there to be one pending message. When I submit three messages, I'll see one pending message in the MSMQ. From reading MSDN, it looks like the ServiceHost is holding the next job in memory until the current job is done, but I can't find a way to turn it off so that the it doesn't hold

I have a sample php script to connect to MSMQ on windows. I can create queues and send messages to the queues, however when i try and open the queue to read the messages I keep getting an Access denied exception. the code is here: http://pastebin.com/S5uCiP2Z I think the main problem is the $READ = $MSMQInfo->Open(2,0); line as i am unsure what the 2, 0 options stand for (i cannot find an reference to those any where - i got that code form another example.) Looking at the docs for MSMQQueueInfo.open at http://msdn.microsoft.com/en-us/library/windows/desktop/ms707027%28v=vs.85%29.aspx I can see

I have been struggling with this problem for a few days now and I just can't seem to figure it out. I have a simple WCF web service hosted on IIS and Windows Server 2008 R2. The implementation of the Web Service is as follows: var completionResult = new CompletionResult(); var updateTextMessage = new UpdateText { TextTemplateId = textTemplateId, Text = text }; var asyncResult = Global.Bus.Send(updateTextMessage).Register(x => completionResult = x.AsyncState as CompletionResult, null); asyncResult.AsyncWaitHandle.WaitOne(10000); if (completionResult.Messages != null && completionResult.Messages

I am relatively new both to MSMQ and Threading in .NET. I have to create a service which listen in different threads, via TCP and SNMP, several network Devices and all this stuff run in dedicated threads, but here also is required to listen on MSMQ Queue from another applications. I am analyzing another similar projects and there is used next logic: private void MSMQRetrievalProc() { try { Message mes; WaitHandle[] handles = new WaitHandle[1] { exitEvent }; while (!exitEvent.WaitOne(0, false)) { try { mes = MyQueue.Receive(new TimeSpan(0, 0, 1)); HandleMessage(mes); } catch

We are using BizTalk Server to send messages via MSMQ. The receiving system requires that each message have the extension property set to a guid (as a byte array). MSDN documents the Extension property of the MSMQMessage here and (in .NET) here . It is simple to set the extension property in .NET: const string messageContent = "Message content goes here"; var encodedMessageContent = new UTF8Encoding().GetBytes(messageContent); // Create the message and set its properties: var message = new System.Messaging.Message(); message.BodyStream = new System.IO.MemoryStream(encodedMessageContent);

This question already has answers here : Is there a way to check how many messages are in a MSMQ Queue? (9 answers) Closed 5 years ago . I'm currently doing it like this: MessageQueue queue = new MessageQueue(".\Private$\myqueue"); MessageEnumerator messageEnumerator = queue.GetMessageEnumerator2(); int i = 0; while (messageEnumerator.MoveNext()) { i++; } return i; But for obvious reasons, it just feels wrong - I shouldn't have to iterate through every message just to get a count, should I? Is there a better way? In C# the answer appears to be no - what you are doing is one of the only ways to

I have created a WCF service using the NetMsmq binding for which i created a private queue on my machine and executed the project. This works fine as such and my WCF service is started and accesses the message using the queue in the debugging environment. Now, I wanted to host the service using the windows service and for the same I created a new project and windows installer as well (This service runs under Local System Account). Then I tried installing this windows service using the InstallUtil command through the command prompt. When installation is happening and during the service host
