WOw... glad to know someone understands this.

I see...

So, if they can block this an allow sumultaneous 'psuedothread' is MTS still not needed?

As you said, it seems to be the MTS is really only needed when doing homogeneous transactions or complex multi-object transactions?

However, isn't another advantage to MTS the role based security?

Hmm... what to do... we are told three tier... but still deciding on how the middle will work. Is it possible to create a scalable 3-tier in VFP without using MTS or any other middleware?
