Properties section is empty on Write Data vi

[CK98]

I was using the Write Data vi from the File I/O >> Storage/Data plugin palette. When I double click the block diagram to configure the Write Data vi, I noticed that the properties window is missing the options listed on the NI website - Please see image below.

I have seen the options being available when I first used the vi but not sure what makes it disappeared. Is there something I need to enable or disable?

The reason I'm asking is because I'm trying to write some waveform into matlab files and I wanted to configure the Write Data vi to be something like the example below.

So I'm trying to find out why is the properties options not showing on the dialog window.

Thanks in advance!

If you drop a brand new version of that, do the properties appear, or is it only on the existing on that problems develop?

What version of LabVIEW are you using?

That particular bit of code that makes that message appear is something called an "xnode", which is a known source of weird LabVIEW problems.  It's hard to say what causes them or how to fix them though.

I did find that the config page you are looking for is a VI file that you can try opening on its own.  I use LabVIEW 2021, so if you have a different version there is a chance yours is in a different place, but see if you can find this VI in vi.lib:

<vi.lib>\Platform\storage\lvStorage.llb\xStorage\xStorageSupp\my_writePropsDlg.vi

It almost certainly is the cause of the problem but it's password protected and can't be opened to check.

You could try deleting it, then opening up NI Package Manager, finding your LabVIEW install and doing a "repair", and see if maybe that file or some other file got corrupted and the repair fixes it.  Worst case, you can always restore it from the recycle bin if that doesn't help.

I tried this on a new vi but I still can't see the properties.

I have tried the repair method you suggested too, but the properties is still missing. So I decided to reinstall Labview 2024 and I can finally see the properties again! The reinstallation probably fixed the corrupted files.

Thanks for your helps!
