How do I set LV exit code or write to stderr?

[jmg]

I am writing a LabVIEW application that is launched by another system. The system will look at the return code (%ERRORLEVEL% in windows) when the application finishes and will also display anything that comes out on stderr to the user.

How do I set the return code from within LabVIEW? How do I write to standard error?

I've searched quite a bit but found nothing.

Thanks for your help.

LabVIEW applications do not run as console apps. But, there are some trick you can play using .NET and Win32 dll calls. Read though this thread:

Running LabVIEW as a CONSOLE app

Thank you John! That is a big help. I had not yet stumbled onto the fact that the program that launched the .exe would not wait for it to complete!
