call instrument

[Andreas Christen]

Hi everyone!

In LabView's help I found descriptions of several VIs I could use, but
I'm not able to find them anywhere. The VIs are called 'call
instrument', 'preload instrument' and 'release instrument'. Are they
normally included with LabView, or where can I get them?

Is there a way to scan the harddisk for VIs? The 'find'-function in
LabView only helps you search for VIs that already are in the system's
memory, which isn't much of a help if you look for a VI you haven't used
before. Any ideas?

Thanks

You don't mention what version of LV you are using. These
VIs were part of the VI Control VIs that were the old way
of doing dynamic loading and calling of VIs. They have been
replaced in LV5.x with the VI server. The VI server is
located on the function palette wi
th the LV icon on a tray
on a hand. The old VIs still exist in a compatibility
library, but you should learn to use the server as they
are a poor substitute for the new things the server can
do.

....but if you want to use the old vi control functions they are found in
vi.lib\utility\victl.llb

But keep in mind that they aren't the same VIs. Open one of them
up and see that they have been reimplemented using the VI Server.
They have to go through some contortions to do so, and a few
esoteric side-effects are different than with the old VIs.
