If you are interested, I can tell you how to download the code.
Best wishes,

Zen,

I think the Active X LabVIEW package is no longer maintained. I
currently

use the Simple Channel Access package, but that has a problem
(here, anyway)

where the PC's CPU goes to 100% when the IOC connection is lost and
then

restored. National Instruments now offers a Channel Access
interface (a

module in their Data Supervisory & Control package that attaches to
their

Shared Variable engine) that I plan to try out this summer. The SNS
project

has a high performance EPICS/LabVIEW interface.

Subject: Active X CA Server for LabVIEW
I am developing a set of applications, some in LabVIEW on MS
Windows and some

written is c++ to run on linux. I chose Epics Channel Access for

communication and data sharing. I am using the Active X CA Server
and the

LabVIEW vi's that go with it which seem to be dated to 2002 and
earlier

(judging from file modification dates). The package was created or
put

together by Kay-Uwe Kasemir. Is this the latest version of that
software?

Are there known problems with the package?

I am asking because I am having difficulties with this software.
Under some

conditions, which I cannot yet reproduce, the server seems to
hang. Stopping

my labview applications and restarting them clears the problem. I
notice

that when I stop the applications both Epics~1 and Epics~2 go away
and they

come back when I start the programs again.

Any help will be greatly appreciated.
Zen
