Error 8 Open/Create/Replace File in Write Spreadsheet String.vi->Write Delimited Spreadsheet (string).vi->Edit Calibration.vi

[Teekayy]

Hi All,

I get an error code 8 when I try to run and save my program. I tried to highlight execution and add probes but it doesn't fail until the last write delimited spreadsheet.

Basically, the program updates a .cal file containing a control number and calibration date like this: 

I can't add a .cal file to the forum because it isn't supported. It also need a Test Setup Files folder and a IR AC DC.cal with this example: 

Would anyone know what is happening?

Thank you,

TK

Hi Teekayy,

Try: Closing LabVIEW completely and run it as administrator. Then try to write to file.

You can attach any file you want if you zip it.

Works fine for me. Could be a permission issue in the write location. Are you running in the development environment or as built executable?

(did you know that index array is resizable? I don't think your program is bulletproof because your flattened timestamp could easily contain a tab character as part of the binary string, which would then corrupt the reading of the timestamp)

Hey XM43,

I can't run it as  administrator because I don't have access from my company and it requires elevation. 

Would there be any other way around this or any other solutions?

Thank you,

Hi altenbach, 

Ahh I didn't think about that haha. I am running it in development environment. It could be a permission issue..

Thanks,

You can move the file or create a copy to "C:\Users\Public\Documents" and then try to see if you can read it from there. If you are still not able to read it, then the file itself has permission restrictions.

As I said, your current technique is dangerous. You need to either use a fully binary file or format your timestamp using readable characters.

Thanks altenbach,

Whoops haha I didn't realize in the properties of the .cal that the read-only box was checked.

Kind regards,

Here's one quick draft. I am sure it needs a few tweaks...

You probably want to write some special sentinel values to the data control if the calibration file does not exist, or handle as error (not shown).

Oh thank youu.

Would you suggest I change my Retrieve and Check Calibration then?
