LV 2011 (and 2012 LV) compilation error. Size not valid in _InstSize: 21

I created a Subvi in LV8.5 to manage events UI outside a main vi. The Subvi gets control references who are registered for the events, through a queue that all actions are sent to a consumer case, nothing complicated. Everything works fine in LV8.5, but now I got all LV2011SP1 on a Windows 7 64 bit and I still get the same error:

"Compile error. Report this issue to National Instruments Tech Support. Invalid size in _InstSize 21 "

which appears 3 times. I tried to open the same code also in LV2012, same error... When you try to isolate the problem, I discovered that by disabling the code in 3 cases of greater consumption that I can get rid of the warning, but then I can't reduce the problem to one...

Any ideas?


Yes, the thing to put 'problem' labview code into a Subvi its own helped me as well.

My speculation is that it forces the choice of another compiler (without the bug) path when compiling the source of the LV.

I think you should file a bug report using the pages of .

In this way we will have better tools in the future.

  • Script error: property not valid value operation

    (in FormCalc)

    I have a form with multiple pages.  The first two are a graph and the other 8 diagrams.  Diagrams have fields of number to the entry measures taken from an inspection process.  The graphic form I have a button to fill in the chart with information from diagrams.

    The click event of the button first retrieves the information from the diagrams and transfer them to the chart.  He is then supposed to change the font color depending on whether the readings are within limits (black for good, red for the worse).

    However, when I go in the preview PDF tab, enter test data in diagrams and click populate, I get an error that I don't know how to fix.  I was not able to find something on the Internet about it.

    Any help would be greatly appreciated.  Here's what's on the screen of the error:

    Script failed (language formcalc; context is)

    XFA [0] form [0] .topmostSubform [0]. LHChart [0]. Button1 [0])

    script =...

    Error: The property not valid value operation; Police is not a default property

    I found the solution to my problem.

    I had the code in the target fields as well as the button trying to change color of font, based on imported figures.  I deleted the code in the target areas and leave the code in the button field and everything worked right.

    Thanks again for everyone's help.

  • Error function not valid advapi32.dll on startup?

    asking again as my first accepts match failed.

    XP SP3 IE8 4 gig, amd phenom II 840 RAM

    No error of harware in Device Manager.

    I ran security scans, ad scans and antivrus sweeps, nothing helps.

    Reinstalled SP3 I found the only copy of functioning of the ADVAPI32. DLL in the subdirectory of MS and may not perform repair or reinstall from the disc with Service Pack 3 installed. This eliminated the problem and speeded up things a little for about 12 hours and then restart in the morning, everything went hiccups again.

    the biggest annoyance is that almost every program or file, I used to open immediately now takes more than 15 seconds.

    I have cleared the cache, temp files, uninstall files, and listen to the system with the cleaning disk, defragmentation, scandisk and other similar things. other missalligned files is nothing major to come several times.

    im hoping to spare me the gig to reinstall if possible.

    any help would be appreciated.

  • Try loading "subject: preferences" and Firefox responds 'the address is not valid' and 'Page download problem'... what gives?

    The question has all the details inside...

    Start Firefox in Safe Mode to check if one of the extensions (Firefox, Tools/menu key > Modules > Extensions) or if hardware acceleration is the cause of the problem.

    • Put yourself in the DEFAULT theme: Firefox, Tools/menu key > Modules > appearance
    • Do NOT click on the reset button on the startup window Mode safe

    Do a clean reinstall and delete the program folder before Firefox to (re) install a new copy of the current version of Firefox.

    If possible to uninstall your current version of Firefox to clean the Windows registry and settings in the security software.

    • Do NOT remove the "personal data" when you uninstall your current version of Firefox, because this will remove all profile folders and you lose personal data such as bookmarks and passwords including data profiles created by other versions of Firefox.

    Delete the program folder Firefox before installing newly downloaded copy of the Firefox installer.

    • (32-bit Windows) "C:\Program Files\Mozilla Firefox\"
    • (Windows 64 bit) "C:\Program Files (x 86) \Mozilla.

    Your personal data such as bookmarks are stored in the Firefox profile folder, so you will not lose data when you uninstall and (re) install or update Firefox, but make sure you do NOT delete personal data when you uninstall Firefox which removes all Firefox profile folders and you lose your data.

    If you keep the problems, and then create a new profile.
