Generate Config ini file trouble with Write key Setpoint[] = [520,85]

[Bacil83]

I'm trying to create vi to generate ini file. Setpoint will be controlled from vi.

is possible in LabVIEW??

Thank you 

[Defaphe]

Yes possible.

Use the palette "Configs file VIs" from "File I/O" and you will be able to do it.

The problem is write key.vi doesnt recognize arrays or clusters.

[Defaphe]

A config file does not intend to store arrays nor clusters into a unique key.

The section is your array, the key your row and value your value.

PS : By using string formating as for example "Voltage;Temperature" and "3;4" you could store an array into a line. Not neat and errors can easily happen.

Hi,

if you want to create ini file that store value from a cluster, you find below an example.

Best Regards.

thank you.

section and key I can do it, but the problem is the values must be in square brackets. 

not in separate sections.

Closed I get was:

 Type[] = "[Voltage,Temperature]"

When I was writing a raw string, but the value is always written with quotation marks indicate is a string.

ini file is for TestStand configuration if that helps.

[Defaphe]

Not possible to do it in Teststand ?

The other way if Labview is not formatting the output as wanted is to create the output as for a .txt file and then use .ini when saving it. But you will have to create the section and the whole file formating.

As an alternative to the ini file , I use TOML file format for such purposes to support arrays and subitems.

This is available in the VIPM.

It results in nicely readable "near ini" file format

Use Array to Spreadsheet string and use as Value with the Write Key-VI.

IIRC, the NI library always quotes strings. And it's a library, not a class (*sigh*), so no inheritance...

This library is (a bit 😊) more complex*, but a lot more flexible (especially if you understand OO):

Carya-Automatisering/Configuration-File-Library: Configuration File Library for LabVIEW (github.com)

IIRC, strings won't be quoted unless you have an array of strings or if they start with a quote. But you can probably overwrite this in a child...

* most complexity is caused by the fact you can choose between by reference (persistent \non persistent) \ by value implementation.
