Can LabVIEW "read" Microsoft Windows Environment Variables?

I wrote a function that finds the value of an environment variable.
Do you think there is a better way? Sorry for the mess.

Same as you write in the cmd:
"echo My PC is %COMPUTERNAME% and user is %USERNAME%".

Of course there is a better solution, The windows API function ExpandEnvironmentStrings.

Hi Max,

Unfortunately you forgot to downconvert your VI. (I prefer LV2019, others may be happy with "LV2021 or older".)

 

In your image I don't see anything that reads the value of an environment variable. All you seem to do is to parse/format predefined strings…

Best regards,

I will have to look at the Windows API way that was mentioned. But the .NET API that I mentioned about 10 years ago in this thread is really the easiest and cleanest way to do it.
