Removing Message from Queue only if user does some operation

messagemsmqpeekproperties

We are having MVC application which reads data from MSMQ.
We are trying to find out a way to read message from queue and remove it from queue only if user has done a successful operation on the queue.
The message should remain in the queue until user completes the processing, the message should not be available to anyone else until the user who is processing the message object has finished the operation.

Is there a property for a Message object to be set as Peeked which will not allow reading of this message again until ether it is put back into the queue or removed from the queue?

We are not sure if using MSMQ is a good idea in this case?

It sounds like you need to use your queue(s) in transactional mode. Then, your client can receive a message, process it, and then commit the transaction, at which point the message will be finally dequeued. While the transaction is active, however, other clients will not see the message -- it will be held in reserve until the transaction completes or is aborted.

This MSDN article has a decent overview of usage patterns for reliable messaging with MSMQ:

Reading data from MSMQ and marking it as read

You'll want to use transactional queues for this scenario. When you receive the message in a transaction it will remain on the queue but will not be available to anyone else. If you successfully process the message then you can commit the transaction which will remove it from the queue. If the processing fails, then you simply abort the transaction and the message will once again be available for the next receiver to process.

You'll need to use the Receive method in order to receive the message off the transactional queue.

.net – Sending message to private MSMQ queue with Authenticate checkbox checked

After initializing a Message object, set the UseAuthentication property to true.

Example for sending a message to an authenticated queue:

private void SendToQueue(string queueMessage)
{
   var message = new System.Messaging.Message(queueMessage);
   message.UseDeadLetterQueue = true;            

   // This line resolved issue for sending message to queue with Authenticate checkbox checked. 
   message.UseAuthentication = true; 

   var queue = new System.Messaging.MessageQueue(@"FormatName:Direct=OS:.\private$\PQ1");
   queue.Send(message, MessageQueueTransactionType.Single);
}
