Why do I receive a  "Fatal internal error: "fpsane.cpp" line 399" when saving my VI?

Thank you.

hi there

the error is shown together with an error number. note the error code and try this:

1) Close LabVIEW
2) Put the key "LVdebugkeys=True"in the LabVIEW.ini file
3) Open your VI
4) Press CTRL+SHFT+d, then press CTRL+SHFT+h This will turn on an object browser.
5) In the top left list box, select the element that contains the name of your VI
6) In the top right listbox, find the line that begins with the error number
7) Click on the F button
😎 Delete this object and recreate it. It will ususally be a wire.

(found that description in an other post, but can't remember the author anymore)

Hi Chris,

But I could not solve the error that way.

Actually, Labview is crashing with this error at any time when I am writing my VI. It simply crashes even if the VI is not running.

I think the problem is not in my VI, because it runs normally in another machine, but must be with the Labview installation. I have reinstalled Labview three time already and the error continues.

Any other ideas?

Thanks,

Gustavo

Hi

If you are still experiencing this issue I would suggest a full reinstall of LabVIEW. To uninstall go though Add/Remove Programs within Control Panel. In the list that is populated there will be an item named National Instruments Software. Click change for this item and this will open another window that lists all the NI software you have installed on your machine. Scroll down and locate LabVIEW and click Remove.

Reinstall LabVIEW and see whether you still experience the issue.

befor you reinstall try to rewrite the vi

[gutoassi]

hum... not yet.

I reinstalled LAbview 8.2 for the 3rd time... nothing happened.

The VI I am trying to run is the example 4128.vi we can find in the forum.

It is still crashing with the same error when I try to save or save as... or sometimes before the VI starts to run when I do any alteration. I think the error might be related to saving the VI. The problem happens to other VIs as well, but only those that are using IMAQ.

Hope you can help me...

Tks,

Gustavo

I am agree with gutoassi, even though labview 8.2.1 releases are very useful, it still have something to be depurated, my VI is ok and I have the same error fpsane.cpp line 399. In order to give a clue with this issue, I am working with CINs and visual C++, some times it just work fine but in a very inconsistent way it crashes some times, what means that my VI is well done.

I suggest someone recheck labview source code and fix some bugs.
