Checking if MSMQ queues exist is hard work so should you bother?

But interestingly, it appears that CanRead is always false even if CanWrite is always true when using a remote private Q.

Do you suppose there are any problems with relying on that?

During Application startup we check the CanWrite property is true documented here:

http://msdn.microsoft.com/en-us/library/system.messaging.messagequeue.canwrite.aspx

which should work if your using the direct format name for the queue's

(though i just tested with Formatname:DIRECT=OS:nonhost\private$\masterqueue and it "CanWrite" and an outgoing queue is waiting for that machine, which will never come)

Doubt that has helped at all...

Hi Koen,

Could you please supply a sample of what you mean as I don't understand how your suggestion will work for private queues on remote machines.

Cheers

Hi,

Actually it is very simple : make an instance of a messagequeue class and ask the queuename. You get a messagequeueexception if it does not exists. If you capture that exception at a predifined place, it 's a very easy thing todo.

Hi Sharad,

The MSMQ Ping utility, as documented here (Test connectivity using MQPing (http://technet.microsoft.com/en-us/library/cc739689.aspx) doesn't have an API for you to call it. And even if you could, it requires Active Directory so is going to be using pathname under the covers.

So it's a great idea but I'm afraid you will have to rely on your own implementation as discussed in the blog post.

Cheers

John

Hi,

Is is possible to use MSMQ ping utility through DotNet code to acheive the same thing. I am actually looking for checking the satus of remote public queue using direct format name.

Thanks in advance
