Hey,

I want to write and application that can do the following:

Tools avaible :
MessageQueue
MS components server (com+)
Dotnet

Scenario:

Message1 is added to a MS queue
A instance of appgetmessage (app1) is created
App1 gets the message in the queue

Message1 is added to a MS queue (while app1 is still busy)
A instance of appgetmessage (app2) is created
App2 gets the message in the queue

Message3 is added to a MS queue (while app2 is still busy)
Now app1 is ready and handles this message

Questions:

1. Can I use com+ to achieve this?
2. Is there a better way of doing load balancing for this scenario?
3. Can Com+ subscribe to and event like "messagequeue file added"?

Thank you for reading this!

I would really appricate any feedback, thought etc on this subject.

Thank you

David

I would try to build the solution differently. I would create one thread
for retrieving messages off of the message queue and then pass the message
along to worker threads to do the work with those messages. You can then
use a thread pool to manage the worker threads and use which ever thread is
currently not doing any work. Your scenarios would look more like:

The Listen thread receives message1 from the queue and asks the thread pool
for a thread. The pool returns thread1 and thread1 processes message1.
The Listen thread receives message2 from the queue and asks the thread pool
for a thread. The pool knows that thread1 is still busy so it returns
thread2 and thread2 processes message2.
etc.
