TDMS Set Properties fails

[Thomas L.]

Hi.

I am currently developing an application which writes some data into a TDMS file.

I have used the TDMS Set Properties VI to add some special properties as meta data.
Basically it works, but only once. Now I would like to know why: The error message is:
"LabVIEW:  An input parameter is invalid. For example if the input is a path, the path might contain a character not allowed by the OS such as ? or @. "

I attached two files. One of them works (the one where only a single Set Properties VI is actually used), the other doesn't - it returns the error above.

Why is that so?

Anyone?

Hello Thomas,

In a rush I can't see the failure.
Could you attach the VIs?
I want to do some tests.

Thanks!

Best Regards,
Wolfgang

Hi Wolfgang

I am sorry that I can't provide any VIs, because I stopped working for the company (this was just some bonus project to do something). I don't have the VIs here, I also do not have 8.2 here, so I can't build a sample application anymore.

As soon as I connected the second wire to MF (or LF, it didn't matter), the VI gave me an error (I don't remember the error code, sorry) directly after the VI where I connected. If only one
 was connected, everything worked fine.
