In LV 7.1, lvanlys.dll and other DLLs it needs are included in the
Rum-Time Engine of LabVIEW. So you don't need to add any files in the
application builder.
Thanks, we got it. Another remark, the HP3852A driver for Labview does
not include the HP4708A (20 channel multiplexer with thermocouple
compensation). On the other hand, the Labwindows driver include this
driver.

You need to specify what version of LabVIEW you have.
Hi. You can select the control (or indicator) with the selection
tool, and then use the arrows keys on the keyboard to move it where
ever you want, as close to the top of the window as you want, or even
