Prevent access to source data

[aviator79]

I am a LabVIEW rookie. I've been given the task of securing some data that a Labview VI accesses. The data I need to secure consists mostly  of Excel spreadsheets containing calibration data and the like. In the interest of preventing data theft, I would like to password protect this data outside of labview, but still allow the VI to access this data. Right now, we are experimenting with third-party password protection software. Is there any way that I can create a VI which will open a third-party password protection program and enter a password? I'm also open to any other methods that I can use to prevent access to data outside of Labview but still allow Labview access to the data.

Hi Aviator -- Welcome to LabVIEW programming, I hope everything's working out well for you.

There's been some good discussion on doing this in the forums, so I'll send you there.  However, this is going to bring in ActiveX programming (to get your hooks into Excel), and that might be yet another thing for you to learn:

In case you're not familiar with ActiveX in LabVIEW, check this link out:

and from the help file:
https://www.ni.com/docs/en-US/bundle/labview/page/using-activex-with-labview.html 

You can also find code examples that you can search for to manipulate Excel data from within LabVIEW with ActiveX.

Thanks and good luck!
