LabVIEW load error code 3: could not load front panel

[zperkins]

Anybody seen this error?  Screen shot attached, also vi.  (it's 6.0.2)

I know this is a stupid question, but does anybody know of a decompiler/disassembler for built labVIEW applications?  I know my VI is corrupt (along with my bakup) but my last build is ok....  I'm fishing now.  As I am going back trying to implement what I did in this version from my notes...I know this is going to take a while to redo..

Thanks,
Zac

Hi Zac,

I could not find any decompilers, and found some forums that confirm that.  Is there no other location where your source is stored?  This is a crazy idea, but I have heard of these issues going away if you use a system restore on your computer.  Of course that is only true if the corruption happened recently.  Sorry for your troubles.

I can't help you with your basic problem, but having a source control system in place can be a major help in situations like this. Moreover the really good news is that the best SCC system for use with LV is free! I am speaking of Subversion, if you would like to learn more do a search on the forum for "subversion" and then come back with any questions.

Mike...

PS: A time of crisis can often be an opportunity to get management to approve things they might otherwise say "no" to.

Thanks Brian and Mike for your responses.  I tried a system restore and it didn't help.

It was a strange thing.  I made some changes...saved...backed up..compiled.
Started up the newly comipled app on the tester and noticed 1 small thing, changed it, saved it..backed it up (without trying it...)

So thats how my vi, and my backup got corrupt...

Anyway..I am also doing research on subversion...I'll see if I can get this going.

Thanks again,
Zac
