block diagram deleted (mostly), but VI still works.

OK, I've made a tiny bit more progress.  I've found two Adds, two Subtracts, two Multiplies, two Ors, and two Nots.  The Case Statement that popped up is about a screen wide and (I'm estimating here) 50 tall, mostly empty, with the functions at the bottom and another normal-sized Case structure at the top.  I don't see many other structures, but I've not made an exhaustive search.

Here's a curious behavior that I don't understand (but maybe I should bring up the Tools palette -- just a second ...  Aha, that changed the behavior.  I was going to say that if I hit Ctrl-Shift (as through I was going to do a Move to Front), the cursor changed from a Plus to a Hand (scroll window) -- now it doesn't do that.  Could there be a Tools problem somewhere?

I also am getting "During the last run of LabVIEW 2013, one or more internal warning were detected and logged".  I've been hitting the Send button ...  There's no option for a followup.  Let me look at the latest Report ...  more than 20 Crash Dump Files and two Text Files.  One is helpful -- "Possible path leak, unable to purge elements of base #0", plus a series of identifiers that say Windows 7, LabVIEW 13.0, etc.

I looked at one of the .dmp files -- there is text in there, but it seems to be related to the build of LabVIEW + the files on my PC + "binary stuff" that is not human-readable.

I'm going to take a break from this for now.  I may be able to work some more on it, or someone may be able to "uncover" a bigger chunk than I could do ...

Has anyone asked NI Support about this?

Ok, I've made some progress as well.  I made myself a copy and started playing with it... I have it back down to a single screen size, but most of the icons are gone, just lines that end and start in dead space.   It's like the icon is there, but invisible.   Wires start and end in the right places, but there's nothing there.

Just something to try (i can't open your VI or I would try it myself)....Do a File -> Save for Previous Version and see if that does anything.

Have you used Quick Drop?  [I'm assuming you are using LabVIEW 2012 or later, though Quick Drop appeared earlier, I think].  You should have a easier time of this that I did, as you have an idea of the functions that should be in this code.  Try the following:

1. Open a copy of your VI.  Go to the Block Diagram.
2. Type Ctrl-F (Find).  Set Search Scope to the current VI (last option).  Search for Objects.  Select a Function from the Block Diagram that you think is there (there are two Add functions that I found).  Click Find.
3. Notice how many instances it finds.  You now want to go replace the "damaged icons" with "good icons", which you do with Quick Drop.
1. Type Ctrl-G to "Go" to the first Found function.  You probably won't see anything, maybe a very skinny dotted-line rectangle.
2. Type Ctrl-Space, the Quick Drop request.  At this point, the previous Step has the Squashed Function selected.
3. Type Ctrl-P, the Quick Drop "Replace" command.  If you are really fortunate, the function will pop into view.  If not, don't worry.
4. Repeat these steps until you think you've covered all of the Found functions.
4. It is possible that you still won't see anything.  First, verify what you've done by repeating Step 2, the Find step, to look for the same function.  When I did this with the original Add replacement, I saw dotted-line triangular (like Add) shapes.
5. What I did at that point was a "Move Selected to Front", Ctrl-Shift-K (which I can't seem to find on the Menu bar ...).  The first time I did this, the Hyper-Tall Case Structure appeared.

Hopefully all of these suggestions are getting you closer to getting your VI back.  Once you've got it back, start using some form of a Version Control System, like Tortoise Subversion (think how much easier it would be to do a Revert or Checkout ...).

4th button on the toolbar after the font selector.  The one with the yellow and blue circular arrows.

Ran this through my VI fixer and it got most things sorted out.  Had to tweak a couple of things by hand and I was not overly careful so triple check that I did not screw something up in your formula.  The goal of my fixer is to get things working and it puts things back into order using the BD cleanup so the final appearance is at its mercy.

Nice.  I actually tried to use VI Scripting to move every object in to coords 0,0 and then BD cleanup.  It broke the VI and returned an error.  I'd be curious how yours works...

Darin,

You are the man!  Looks perfect.  Is this "fixer" a NI product or something you mixed up? 

Thank you again!

Darin and LabVIEW is like Harvey Keitel in Pulp Fiction. (See also) 😄
