I am not sure that it is necessary to lock safearrays. I don't see why it should be important across boundaries, since you'll never be able to access an array...

Hi Michael, I haven't had a chance yet to scrutinise your work - I am out working on-site for a client. But I was wondering - why not just lock the safearray...

No probs. I'm not convinced that a permanent lock is the best policy, and I don't think that locking should be optional. (See Marc's comment about the API ...

Hi Marc, Seems I didn't think this through. Let me give it another try. As long as the SAFEARRAY is being accessed through the safearray_t class, there...

Sounds good, remember that it's perfectly legal to take a [in] SAFEARRAY and alter it _in-place_ before passing it on to another COM method. In-proc, that...
