LabVIEW 8.20 application quits unexpectedly

[Christ0phe]

Hello,

I just finished migrating a large data acquisition application from LabVIEW 7.1.1 to 8.20. Everything looks good except that sometimes - and I have not been able to understand exactly when- LabVIEW 8.20 quits completely by itself, no error message, it just disappears from the screen and from the list of Processes of my Windows XP.

Is there a location on the hard disk where LabVIEW stores usefull debugging information such as in which VI occurs the issue that triggers it to quit so suddenly?

Thanks,
Christophe

Greetings Christophe,

LabVIEW stores error information in two places.
Please refer to the links below to see what information can be found where.

'general' error information, created by LabVIEW or Windows can be found here:

When LabVIEW shuts down due to an internal error, this information can be found in the LabVIEW Temp Directory.

Thank you for your answer that unfortunately does not solve my problem. Yet I can see some .tmp and .rsc tracks when Labview restarts after a brutal exit but I cannot see any track that would tell me why or which Vi is responsible for quitting Labview so suddenly. Also as I pointed in my original message there is no .cpp message when Labview quits, it is quitting suddenly without any Labview or Windows error message. Never had that with the same application running in Labview 7.1.

The articles that you refer to are based on Labview 7.1 maybe the situation is different in Labview 8.20?

Thanks,

Christophe
