Lettura da un file di testo e confronto

[Akroma96]

Buongiorno a tutti, ho poca esperienza con Labview e avrei bisogno di sapere se è possibile selezionare un file di testo e cercare in questo file di testo se un codice che inserisco io manualmente o tramite acquisizione è già presente. 
La versione è quella 2020 a 32 bit per necessità di progetto.

Yes, all that is possible!

There are file functions including functions to read from text files.

And there are string functions including functions "MatchPattern"…

Yes, sure. LabVIEW is a programming language!

Then you should start with coding.

(Or better start with sketching an algorithm on a sheet of paper…)
