I am working on an n-tiered application written in VB DLLs running under component services/COM+ and part of the application requires asynchronous functionality. To implement the asynchronous functionality, I am using queued components where MSMQ delivers the marshalled data without forcing the client to wait. That part is working fine.
Here is the tricky part . . . if the asynchronous operation is completed before the client application is finished with a specific task, I would like to notify the client that the job has finished. Queued components, by definition can not have any return values or ByRef parameters, so the callback can not come from the queued components. Is there an efficient way to deliver a message back to a calling client when an asynchronous process has finished?
Thank you in advance for any help you can offer!
