cleanup diagram not working

[Arcus]

Hi Gurus, I am working on an entirely messed up and huge program and slowly cleaning it up. So I am using the cleanup diagram tool to fix some parts of the program and work my manual cleanup from there. However It doesn't work on the main vi but works on other vis. My question would be, is there a particular setting in labview that stops the cleanup diagram tool not to work? I am using LV 2015.

• Make sure nothing is selected when you press cleanup.
• Are any structures configured to be excluded from cleanup? (RIght-click structure...exclude from cleanup)

Hi Altenbach,

So far I checked, nothing is selected and recheckd the structure and they are not excluded from cleanup. I also check the outside structures just incase the whole loop is excluded from cleanup, but it's not.

Maybe it just gave up.  😉

I've seen this a couple of times. Rebooting my development computer has cleared it up so far...

Maybe post your code and we can see if we can clean it up.  That being said I have seen the cleanup tool refuse to work, if the block diagram grew too much as a result of the clean up.  There is a maximum front panel and block diagram size, and once you reach it strange things happen.  BD Cleanup generally expands things so they put in some kind of check to ensure that it doesn't grow too large after doing the clean up.  Is it possible your BD is this huge?

Hoovahh thanks for that link. I haven't seen that before.

I have seen this on small diagrams though. I never tried to figure out what was happening due to low number for occurences and it worked after a reboot.

I've also seen the cleanup not work on small diagrams and LabView crashed as a result. This was on a new i7 PC with 16gb of ram, and tech support never was able to figure out why it happened. They just told me to reload LabView...

Hi All,

 Thanks for the feedback. I tried rebooting the system but still no luck.  Our program is so huge after ~15 years of gradual addition and changing of the code by only one person that learned labview from books and mocking around experimenting stuff. its a massive while loop and thousands of loops here and there. Refactoring is a pain so far I am still motivated to clean it up.:manmad:

Sounds like the too large block diagram could actually be the real problem.  Luickily you can cleanup selections of code by selecting it then performing a cleanup.  I also think you can cleanup structures by right clicking them.  Good luck, some times it is easier to just understand what the program does, and start over, copying parts of the existing program into a better design.

Hi Hooovah,

Youre suggestion on creating a new came to me long ago and I am doing it on the side. However the cleanup on selections of the code is the one that is not working. I don't want to do a cleanup on the whole code as I have a gut feel it would do worse and make it bigger so I am cleaning it up piece by piece (selection by selection) but unfortunately, it doesn't seem to work... Came to think. what have I done wrong?
