I'm starting to play with MSMQ and have a really newbie question...
I can effectively write to my Queue with no problem. However, what event is
raised when something is added to the queue. Currently, I'm polling the
queue to see if it has anything in it and then processing accordingly. But
that seems like an awkward way to handle messages b/c I might interrogate
the queue x number of times when there's nothing in it. If I could just
wake up the client app when anything is added to the queue, it seems like
it'd be much better solution.
Is there a way to do this, namely, for the queue to send a notification that
something has been added or that it has stuff in it?
TIA,
Bill

One way is to implement a windows service which incorporates Timer object
for checking the Queue and notifies the other components in case of new
message.

Take a look at MSMQ triggers.

Ali:
Thanks for the suggestion, that's actually what I have now....I have a
background thread and a timer in it that's doing the polling , and it
definitely works. I was just wondering if the Queue had anything inherent
in it to notify me.
BTW, I noticed you earned the MCAD. I've been thinking about it for a
while...can you recommend any study material?
Thanks again,
Bill

If you use .NET Framework (as I suspect so since you post here) you can use
async programming. Look att BeginReceive / EndReceive in the MessageQueue
class. Read more at http://msdn.microsoft.com/library/de...asp?frame=true
In fact, that whole chapter might be interesting for you. http://msdn.microsoft.com/library/de...asp?frame=true
Also there is at least one other article about MSMQ and services at http://msdn.microsoft.com/library/de...asp?frame=true
