Save and Write Configuration Settings

[Tobi_J]

Dear Labview Users,

 

I want to build a VI that can read and write the settings for the controls. The VI should be able to write certain config-settings and be able to read it in the same control.

 

I found Labview examples (Read Configuration Settings File.vi  and Write Configuration Settings File.vi  both attached below) and the writing of the control-doubles via the Write Key.vi  works just fine.

 

The problem arises when the config-settings should be read, since a “control” in Labview cannot be used as an “indicator”.

 

Basically I want to have both VIs (Read Configuration Settings File.vi  and Write Configuration Settings File.vi) in one VI and that the indicator/control on the front panel is the same.

 

Thanks for your help

Tobi

Read Configuration Settings File.vi

Write Configuration Settings File.vi

Look into “local variables” and “Property nodes (Value)”.  Both can read or write to both controls and indicators.

You can also see a very convenient implementation here - https://decibel.ni.com/content/docs/DOC-15349

I normally just use the OpenG VIs:

The main reason I don't use the OpenG panel VIs is that quite often I want only a subset of the controls and it's important not to handle some of the controls I want to avoid. Usually it's either a matter of building the refs array manually or using one or more of the Controls[] properties and then deleting the unwanted refs from that.

Thank you guys very much,

the hint with the local variables helped me, since i am using labview 8.0

Your are right, these VIs should have some filtering functions. E.g. All controls/indicators where the Label Name starts/ends with a certaing character "...$".

Or just have an array of controls refs and only use thoses.
