Labview has detected an error and it must be closed

[tonitpp]

Hi everybody,

I have built a Data Acquisition Application and after a few hours running an error message window appears saying something like that:

LabVIEW has detected an error and it must be closed.

Then, my application continues executing if I don't press the accept button that figures in that window as if nothing would have happened (A part of my application leaves working but other parts not) but If I press the accept button, my application exits. What could be the cause?

Thanks in advance,

ToNi.

Hi Toni,

Could you give me a bit more information regarding this please? the VI's your using and if under the development environment your able to catch the error number? If it would be possible for you to upload the source in a zip file to here that would also be useful.

Thanks,

Hi Toni,

I had this happen to me before the Holidays.  Unfortunately, it did not give any error number.  I may still have a screen capture of the error message, and I think I posted a message about the situation.  This is using LV8.2.

In my case, the error came up while editing the VI, or immediately after pressing the run button.  There was one crash which rendered the vi unusable, so make sure you have a full backup.

I can't remember what I was doing at the time.  I did have some other problems, especially when setting properties of graphs, but that gave me another error message.  The problem dissappeared since. I suspected the RAM in the PC, which was changed; and I haven't changed the properties of the graphs since.  I'll look for the thread and the error message and post links in this thread.

Don't forget to do a full backup of your work.  And until the error message dissappears, save often.

EDIT:  Found the error message screen capture, here it is:

However, you are indicating something potentially quite different.  You say that your application kept running, even when the error message is displayed?  Is that correct?  Usually, when you get the above message, it has already closed the application. 

Did you get a similar error message to the one shown above?

Hi,

First thanks to everybody for your help. Well, I think I have solved the problem, the main problem was that I called a vi through a reference node and this vi didn't exist because I changed its name and I forgot to update its name in the diagram block when I called it.

Many Thanks again.

ToNi.
