Hi, I'm trying to cleanup a VI, and whenever I hit auto cleanup LabVIEW crashes and when retsrated it doesn't even say it previously crashed. I narrowed down the problem location to a for loop. The wierd thing is that I went through all the wires and objects within the loop and did auto cleanup on them but it doesn't crash. So why when I do it on all combined does it crash? I wrote a comment in the loop that crashes to show which on it is. I'm on Windows 7 LabVIEW 2010.0f2 32bit I did see this posting http://digital.ni.com/public.nsf/allkb/599FB39777BDB12486257514005B7293, but even when doing it manually as suggested it still crashes. Thanks, Matt

This crash corresponds to a known issue in LabVIEW (CAR #298911), which has been fixed in the forthcoming LabVIEW 2011 release. I have attached a copy of your cleaned up VI from 2011, saved for 2010. You might try to copy the block diagram into a new VI and see if that still crashes LabVIEW, but otherwise an upgrade to 2011 when it's available should clear up the problem. Hope that helps.

From Friday, April 19th (11:00 PM CDT) through Saturday, April 20th (2:00 PM CDT), 2024, ni.com will undergo system upgrades that may result in temporary service interruption.

We appreciate your patience as we improve our online experience.

Auto cleanup crashes LabVIEW (and VI isn't even that large)

Solved!

Still a problem in LV2015. I recently upgraded from LV 2014 to LV 2015 (No problems in LV 2014) , then LV2015 has unleashed a whole can o whip ass on me now. I noticed in my code I have a mixture of Older flat sequences (Dark Gray) and Newer (Light Gray) flat sequences. The only solution I have found is replacing all of the dark gray flat sequences (older) with light gray flat sequences (newer)...however, it's not that easy. Typically, the whole block diagram explodes to 10 times its normal width, rendering the Auto clean up unusable. After many hours of pushing and pulling the block diagram around...I can finall regain control. This is a huge time waster. I don't have the time to "manually" clean up my code.

There's a difference between dark gray flat sequences (earlier version of LV) and light gray flat sequences (later version of LV). If you have dark gray flat squences in LV2015 it's falling apart. I've spent more time fixing code than actually working on my projects.

I'm trying to reach out to NI for support, but, I haven't got any good news yet.

One of NI's favorite blame game answers, "Your Block Diagram is Too BIG". Ok, if there are limits on the block diagram size, then put the limits on the block diagram. Don't give me an unlimited canvas to paint my code on, allow me to compile, and then at some point come back to me as say "Your Block Diagram is Too BIG". That's just lame.
