MSMQ

Re: MSMQ

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.

Re: MSMQ

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

Re: MSMQ

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
