"investigate previous internal error" every time I start LV 8.2.1

[dsavir]

Hi,

Every time I start LV 8.2.1 I get a message "The last time you ran LabVIEW, an internal error or crash occurred at fpsane.cpp, line 401" and it asks if I want to investigate now. I don't have any problems while running the application, compiling it or building an installer. Does anyone have any idea what this is and if it's important?

Thanks,

Danielle

This occurs mostly by your front panel controls.

Try a search in this forum with the keyword - "fpsane.cpp"

You can get a couple of solutions.

Post if further help required.

Thanks,

Although the VI runs, it may have a strange entry somewhere. 

I did get that message a couple of times.  From what I can recall it was when running omething & I had to kill the execution, or shut down LV completely.  Upon re-start of LV a similar message popped up.   The message did not re-appear at the next start.  Maybe I inadvertently fixed it without knowing..

Try loading your VI, running it once.  Saving it.  Shut down LV.  Restart LV.  And check to see if the message continuous to appear. (you may have to repeat the steps once).

Oh... Do you have any Disable Structure which has some unfinished code iside it?  I do recall that...  Who knows..  (???)

Hi dsavir,

A DWARN like the one you experienced means that something unexpected occurred in the LabVIEW program, but not necesarily something that is going to cause you problems.

Looking through our database, I found several bug reports (aka: Corrective Action Requests or CARs) filed with R&D about this error, but they all seem to correspond to LabVIEW 8.2.1 (ie: they are probably fixed in the latest version).

Do you have access to a newer version of LabVIEW that you could try?  If not, if you can tell me how to reproduce it in 8.2.1 I will try here and hopefully verify that it has been corrected in 8.5.

In any case, you probably don't need to worry about it if you haven't noticed any other problems.

Hi,

Thanks to all of you for your suggestions!

About the LV version: I did try out LV 8.5 and this error did not occur, but LV 8.5 had so many other problems (mainly building problems) that I gave up on it until my company upgrades to LV 8.5.1.

This error occurs every time I startup, whether I run the vi or not. I do not think I have unfinished code in a disable structure - I use it mainly to compare two sets of code that both run - to know what will give better results.

I'll think I'll take Eriquito's advice and won't worry about it as everything else is running fine.

Thanks again,

Danielle

LV8.5 should be fine.  What problems are you having with it?  (build app?)
