Labwindows CVI 7.1.1 interactive execution and NIDAQmx

[markus kossmann]

Are there any known issues calling functions from NIDAQmx in the interactive execution of CVI 7.1.1 ?

With DAQMX 73.0f0 I got sometimes  "interactive execution caused external process to terminate" messages when calling DAQmxClearTask(). 

Now after the update to DAQmx 8.3 it's even worse.   I've seen Windows blue screens at least 3 times.

Since the PC rebooted immediately I could't  write down the information from the blue screen. But I saw one dll with DAQmx in the name listed.

Unfortunately I'am not able to reproduce the problems exactly. Calling the same functions  a few minutes later may work again.

And running that code as normal program never caused these problems.

Hello Mr. Kossmann,

there has been an issue with the IEW in CVI 7.1 as far as I can see (thread was killed from the IEW that should not be killed), showing the error message from time to time that you posted. The target version in this case was 8.0, where this issue should be fixed.

In order to verify this, I would like to give an evaluation copy to you for CVI 8.0. It can be downloaded from:

https://sine.ni.com/apps/utf8/nigb.guestbook?code=GB_EVALCVI&lang=US&gb_prof_id=1323&scode=&pr=1323&...

Please let me know if this resolves the problem or not. In case not, i will get back to R&D for further evaluation.

Regards,

C.L.
