Couldn't open the block diagram

[azadplc007]

Dear All, 

Yesterday i was working on my VI, its working fine. But, when i am opening same vi today, i couldn't open my block diagram. I have tried such ways that, open the Vi from another project library, WO project library, but still no response. i have searched in forum also, i didn't find any solution. please help me about this. i have attached my Vi and version is 14

Hi azadplc,

when there is no block diagram in the VI then you cannot open it!

Somehow you managed to remove the block diagram…

The solution is very easy: get an older version of the VI from your SCC repository! You don't use any SCC tool like SVN or Github? Shame on you!

Then you should take the next easy solution: get an older copy of your VI from your backup! You don't use any backups? BIG FAIL!

Yes I have back up. 

But i want to know, what we have to do,  in case,  if some one faced same problem in  future . Some BIG MINDED people like you, will be on forum. So that only i have asked here.

NEVER remove the block diagram of VIs in development.

Keep a backup of your development source code. Even better: use a SCC tool of your choice!

ONLY remove block diagram when you want to send VIs to a customer (or similar person). Even better: use packed libraries (lvlibp) for this very purpose!

What Happens When I Save My VI and Remove Diagrams?

This really is a feature that needs removed from LabVIEW.  Pack Project Libraries are a direct replacement and do not have the possibility of running into this issue.
