overwriting a file woithout confirm

[x@no.mail]

Hi LabViewers,

I have a file which I use temporarely and want to overwrite each time I
use it.

I use "Write Characters to File VI" with 'append to file' set false.

Problem: I have to confirm 'replace the existing file' each time - it
should be an autimatic system 😉

Thanks for any hints

If you look inside Write Characters to File.vi, you'll find Open/Create/Replace File.vi. This has an input called advisory dialog?. The default is true. Make a copy of Write Characters to File.vi (so that future LabVIEW updates don't overwrite changes) so that you can pass a false value to Open/Create/Replace File.vi.

I copy the original file to a back-up file (can be very handy in case it contains valuable data/info).
Then I delete this original file.
Following you can create a file with the original filename.
It will not be the most efficient method, but it works for me.
