NI-VISA Programmer Reference

[wz2b]

Is there a newer version of the NI-VISA Programmer's Reference Manual somewhere?  All I can find is this:

    https://www.ni.com/pdf/manuals/370132c.pdf

from 2003.  What would be even better would be if there's also some kind of SDK.

I recommend the following resource: NI-VISA 15.0 Help 

It is also installed as a CHM help file in your computer when installing the driver: 

C:\Program Files (x86)\IVI Foundation\VISA\WinNT\NIvisa\ni-visa.chm

As far as I know the Visa specification didn't change since, even though some implementations/libraries might have evolved (e.g. for NET).

I'm using this old reference to call all library functions in the latest Visa library (visa32.dll) and didn't have any problems.
