Hello,
If you are encountering the error:
"LabVIEW: (Hex 0x692) The string contains an unexpected null character.
The top-level VI
ELVISmx_subSelectLogDataPath.vi was stopped at File Dialog "FDG2" on the block diagram of ELVISmx_subSelectLogDataPath.vi "
Then you are in luck.
Here is how I fixed it for me, and hopefully it will help someone else who is having the same problem and is lost.
First off, I encountered this error using the ELVIXmx for the myDAQ. I was getting this error and the description for the File Dialog was that it was no longer supported and to swap to the new File Dialog Express VI or some bs.
DONT DO THAT! I tried to do just that and the new express one just broke more stuff.
Instead, just delete the path to the pattern (all files) port. For some reason the LabVIEW 2019 doesnt like the multi-select files or whatever, and is for some reason reading an NULL with this connection.
If you have "Pattern Label (all files)" connected, delete the link.
It might also be called "Format name". Delete the link to the File Dialog.vi and try it again.
Hopefully this solves your issue.
Refer to the photos for more reference and to see if you have the *old Version* of File Dialog that I am referring too.
