>Can anyone say how thread-reliable the _tally object is with a MTDLL (subclassed from a timer control or formset control, not session or custom)? I was thinking that if multiple instances did some SQL and were asked for _tally, they would all say the same thing regardless of how many rows were asked.

_Tally is a local system variable. When you instantiate a COM server, even one configured as an MTDLL, you get a new memory space. You can't access a variable in another DLL instance's memory space unless you program some interface to it (public;y exposed method or property).

HTH.
