Hi,
I would like to know what is the advantage of this reference solution compare with using a data queue + semaphore? It should be similar with command queue in the active pattern of SciWare but it has the semaphore to protect the read and write data.

Best regards,
Thang Nguyen

I view it as child needs to be able to lock parent, but parent shouldn't lock child.

If you're facing this situation, I think the correct answer is to eliminate the inheritance relationship in favor of a container class that contains both "parent" and "child" as separate internal objects. Then you are back to only having mutex locking on an entire object.

Can you Stephen please update the document to contain reasons why DVR terminals do not support dynamic dispatching?

I never did get around to updating the white paper, but I typed this up today:

Good info AQ. Can I talk you into a cut 'n paste into the white paper? I'm much more likely to be able to find that again than a post in the Idea Exchange.
