>You definately want to use the MTDLL if running under MTS. You use it just like the Single threaded DLL...in other words, don't do anything different. MTS handles the threading. Multithreaded is misleading. The DLL is really Apartment Model threaded. If you use the Single threaded, then subsequent calls will be blocked, slowing down your application.


Thanks - I've just seen an article in three parts written by you about VFP and MTS. I'll be reading that tomorrow morning.

Cheers.
