Well, I'm sure if we thought about it enough we could come up with a more
advanced (AKA complicated) method, but if simple works then that's what I go
with. Hope it does the job for you.

you're probably right about the global status flags working well enough.

thanks.

Using On Error statements and global status flag variables should do the

trick.

Hth,

Hi Doug,

Oh, for instance, get some info out of a particular dictionary object. I

test if it exists, and then when I go to get info out of it, I get an
error

because it no longer exists, because some other event handler has removed
it

(as it should); but these types of conflicts where objects are created
and

modified and deleted by more than one thread really could use some atomic
control, and I was wondering if anyone had already solved this issue.

It's not always dictionary objects, it another example two different

threads
need access to a single resource in a third com automation server; each

one
needs it for a few statements, before it can then be released to be used

by
another thread. without some atomic control here, they could end up

interfering with each other's use of it.

thanks.

Chip

What specifically are you wanting to do atomically?

Hi all,

I need to coordinate some activity between various event handlers and
timer

generated events in a VBScript. I was wondering if there was any way of
having atomic operations in a VBScript to do this? any other

suggestions?

thanks.
