Can LabVIEW "read" Microsoft Windows Environment Variables?

[Hooovahh]

I agree with the answers posted here, but for completeness I wanted to link to my tool that reads and writes environment variables that I wrote a long time ago on LAVA.

Thanks for your help, it works fine.

@MikeMesolella:

I cannot find that method call anywhere on my LV 2022 .NET pallet. Could you explain where it is please? Thanks in advance! Maybe send a code snippet.

Just re-read the whole post again and you will find your answer. As I’ve answered before. Have a great day.

Ah yes. By bad for not reading the full thread. Works fine.

Even so, ... buried much? Phew!

Also, I do like the call into Kernel32.dll. I've made CLN calls to Win APIs before. But there are complications there as well. Nothing's perfect, I guess.

Thanks again for your help! 👍

Can you use the "set" command in system exec?

That's what my (terrible) code I posted earlier does.  It will have examples of parsing the command line calls.  Reminder again that the code is at least 14 years old, and probably bad.

I have to think it hasn't changed from "this_parameter=this_value".
