Hi I am trying to workout the best implementation/approach to the following problem I have customers using our win forms application which has a plugin which will connect to the Azure Queue to check if there are awaiting invoices for the connecting customer at pre conf intervals.

I have an array of data (arrData) which I loop around (10 elements), calling an ajax request on each. As it stands at the moment each ajax call is made in parallel. This means the server receives 10 calls all at once and sends back the data in whatever order it calculates each in. To relieve the server slightly I want to now queue my cal...

Hi there, is there any best-practice-pattern for implementing a queue for sending ordered requests? I know this hits the logic behind ansynchronous requests, but in special cases one needs queued sending :) Here is my first attempt: this.queue = [], this.sending = false, send: function(message) { if (this.sending) { this...

But i don't like it (reason posible memory leak). puthon script called by cron and do a little part of task. But i need to solve problem of one working active sript ...
I created a script to monitor a set of queues, and, while it works perfectly with Remote Private Queues, it doesn't work with Outgoing Queues. I made an experiment by removing everything but the essential from the script, and I created the following test script: var info = new ActiveXObject("MSMQ.MSMQQueueInfo"); info.FormatName = /*<Qu...
At the moment I am using RMI or hessian library to communicate between my server and clients (via a LinkedBlockingQueue). Now I read about JMS which could be used in this area too. Is this correct? If yes, would you mind to give me a simple list of advantages/disadvantages, because it seems to be a pretty complicated and 'fullblown-enter...
I would like to create a Rails app that would allow users to control the serial port of the host server. To keep some order to the serial commands, I would like to have some sort of queue system that would only allow one user at a time to issue commands, with a time limit. When their time expires, the next user in the queue is given cont...
I wish to setup a database table that will be used as a message queue. The table will have messages inserted into it with a unique id and a timestamp and a status of 'PENDING'. Assuming that the insertion into this table is properly handled, I wish to know what is the best way to transactionally process messages from this table using a ...
How Can i check whether a message Queue already exists or not.. Reason for this is i have 2 different applications one creating a queue and other reading from that queue..So if i run the Client which reads from the queue first than it crashes. So to avoid that i would like to check first whether the queue exists or not ...

The catch is that the recording is done only when somebody talks near the iphone (I've managed this part I have a recorder active all the time and get it's average and peak values). The problem is wh...
Hi guys, I am new to this technology so this might have been asked before and I do not know - so sorry to start with. I have a message Queue and I am designing a WPF interface for it. The actual message queue(MSMQ) contains information to do with trains(model trains) so i need to show their exact location in real time. From section t...
So, I have a function that executes on a .click() event. I want to know how I can ensure that the function won't run again before the first run is complete? So, if a user clicks 3 times, the function will run 3 times, but run1 will finish before run2 starts. I was thinking something like .queue(), but am unsure how to implement it. $(d...
I have a few different apps which need robust database-backed job/task queues, and so far I've had trouble identifying any promising candidates. I'd love some suggestions! BTW, by database-backed I intend something which persists job data and status to a JDBC DB for reliability purposes. Oh, I'm specifically looking for a library. I'm ...
If I wanted to make a custom implementation of a Queue is correct to say that I can choose whatever order I want (not FIFO) but I must always respect the fact that the element to remove is that positioned as "head"? but for insertion operation I'm not obliged to put the element to the tail (like into FIFO)? ...

I'm learning queues and I came across this piece of code. It's from a book, so I can't post the whole code here but what I'm posting will be sufficient. More than a problem, I just want to confirm that whether my understanding of this code is correct or not. In the function, delete_ap(), the 'if' statement calls qretrieve() function and...
