Write to text file returns no error even if the underlying file is deleted

[DennisPrince]

Hi,

I'm using a CompactRIO and writing to a text file underneath the C drive.

I'm running into an unexpected situation when I am trying to error check my file handling.  I assumed that if the underlying file being written to that was created by open/create/replace vi and written to with the "Write to Text File" vi, would return an error if I delete the file from underneath it in the file system., yet there is no reported error and the function carrys on seemingly successfully writing to a file that has been deleted.  

Anyone know why this happens and how to potentiallly remedy?

How you will delete file when your reference is live?

Ouch, this obviously isn't ideal but is probably down to the filesystem on the CompactRIO.

I would consider putting in a check - doing something like getting the file position from the file might return an error if the file no longer exists.

Thanks for the idea. I'll try that and let you know how it goes.
