Make TDMS functions robust!

[TiTou]

TDMS could be very useful if they were not so badly handled. The need for files that you can read and write concurrently does exist but TDMS fail to address it right now because of the lack of stability.

Create a TDMS, close the ref and then pass the closed ref to any TDMS function, LabVIEW crashes instantly...

Try use NI's TDMS viewer for a very large file, you get a memory error.

For now I still use WAV file and when customer send me their large TDMS files I always have to struggle around to parse them.

Really TDMS could be cool with a little effort from NI.

Hi Titou,

Thank you for explain the details.

For the first problem, would you please let us know the machine configure? Is that 32-bit XP or else, how much of the memory installed? Is that convenient for you to make up a simple VI without anything confidential and send to me, that would be great helpful for us to investigate?

I also understand the requirement for supporting other data types for setting TDMS properties, especially for clusters. I can't promise this would be happen in which future release, but we take the requirement seriously.

TDMS 2.0 should be able to work with LV 8.6. And TDMS Advanced API is introduced in LV 2010 version, installing TDMS installer cannot install Advancend API, you have to install LV 2010 if want to use it.

Ok, I've just run the TDMS 2.0 installer from the link you gave and nothing changes (the TDMS version is still the same) and LabVIEW still vanishes when I run my VI.

I have 32 bit WinXP Pro SP3 on an HP Compaq 6910p laptop but I had the same issue on à desktop HP Compaq 8000 Elite (same OS).

Here's my laptop system info :

I'll do that.

These issues have been addressed in LabVIEW 2014.
