Multi-threading isn't always all it is cooked up to be. For an internet app I am working on (VB Com objects) we do invoicing at the end of the month. Usually in one or two days. Multiple users were calling the invoice server all at the same time. Multithreading was highly effective in bringing the server to its knees. We have now implemented an 'orderly' queueing system to deal with multiple inovice process one at a time.

With that said, not having multi-threaded COM objects is about the only big weakness I see to VFP as a middle tier component, and even there, Web Connection has proven it's efficiency as a middle tier server (instantiate a couple of servers if necessary, it's only memory).

No matter what the gloomsayers think, if Ken is correct about making VFP multi-threading (and I'm sure he is - he might even be helping!) it shows the kind of commitment and effort MS are placing in the product. Much better than advertising, I'd say.
