Hi,
I am trying to learn how to communicate with instruments using GPIB. I learn by seeing how someone else did it and go from there. I have an HP3478A Multi-meter which is the instrument that I have example code for. It came from NI when I downloaded and installed the VISA driver for it. Well, I followed the instructions on how to use it and when I compiled it, LabWindows complains that I do not have the ividmm.h file. I checked the includes for the example file and it definitely needs that file to compile. When I made my project, I chose to use the C file and not the LIB or the FP for that instrument so I can understand how to write code for that instrument. I will try and see if those will compile, but I doubt they will. Where can I get that H file, or do I need to install some more code for VISA or IVI. I just don't know what to do next. Thanks.

Hi @kerplatz,
If you have VISA and IVI drivers installed, the ividmm.h file should be in the IVI Foundation folder found in your computer's program files:
C:\Program Files (x86)\IVI Foundation\VISA\WinNT\Include
C:\Program Files (x86)\IVI Foundation\VISA\Win64\Include
It's also in the ...IVI Foundation\IVI\Include directory
Hope this helps!
Cheers,
