CVI 8.5 IDE fatal errors

[menchar]

Several times now I've had CVI 8.5 crash on me when I'm closing an open project and opening another one.

I get a CVI popup saying Lab Windows / CVI will be aborted   , location 001B:10258287.  It is not an OS popup - looks to me like an exception that the IDE is catching but doesn't know what to do with.

It happens when I'm loading a new project, and the IDE is prompting as to whether it should save modifications to the previous project that's being closed/unloaded.  I answer yes to the save prompts then it comes up with the error popup.

I've also experienced several fatal errors from in the 8.5 IDE, though not always under the same circumstance.  That last (a few minutes ago) was --seemingly-- on a Got Focus event.  I just switched back to it and POOF... fatal error.

Yup, the 8.5 IDE seems to be notably unstable.   I'm not doing anything out of the ordinary and it doesn't seem like you are either.  I can't correlate it with anything specific yet, but there is something rotten in Denmark.

Hi menchar,

Unfortunately I am not able to replicate your issue after following your steps.

When you create the new project, in the New Project Options window, what settings do you select (ie. Build Options)? Does the error only happen with a specific project that you are unloading, or is the issue random? Will the error occur with unloaded projects of various sizes?

Nestor -

Well, the problem is I can't correlate it with anything other than closing a project, saving files, and opening another project.

It doesn't happen every time.  But often enough to be really annoying, as I've lost changes because of it.

It's not a Windows system error popup, it's a very cryptic CVI message with very little to go on other than what looks like a memory address.

The next time it happens, I'll make a screen shot of it and post it.

Just had another one.. CVI IDE fatal error popup.

Title: Labwindows/CVI Message

Unrecoverable Internal Error at 001B:10064822

Labwindows/CVI will be aborted

[OK]

after clicking OK, CVI started shutting down and I got one "Panal, Pop-up or menubar handle is invalid" error message for what seemed like every file that CVI closed.... about 12 of them in total, one prompt per tab that closed + a few extra after all the tabs were gone before CVI shutdown. This one happend after I opened a UIR panel (that normally has no errors) on Vista.

When I re-opened the workspace from my last crash (posted above) the UIR file I was opening had the target source file set to a c file from the wrong project.  The target file set after the crash was never set as the UIR target for the project, but was the target from one of the other projects in the workspace.  When I tried to change the target back to the proper file, I couldn't select any of my other c files from the project or workspace  until I opened them.  I'm not sure if the target files normally have to be opened before selected as a target file?

I liked the Bug reporting feature that was active during the 8.5 Beta.  Is there any reason why that can't remain open?  That seems like a better method of reporting bugs then posting to the forums.  It would be prudent given the number of 8.5 bugs posted to these forums so far.

Hello Greg,

We very much want to get to the bottom of these crashes you've been seeing. But in order for us to be able to investigate them, we will probably need to be able to reproduce the sequence of events that led to the crash. Can you tell us a bit more about what you were doing when this last crash happened, for example? And if you preform that sequence again, does it still crash?

Also, can you confirm that you have version 8.5.0.279 of cvi.dll installed? The reason I'm asking is that the exception address that you are reporting can be helpful to us, but only if we match it to an exact build of CVI. Since you also used the 8.5 beta, I want to make sure that you ended up with the expected version of CVI in your machine.

Finally, and assuming that you are using 8.5.0.279, you weren't by chance, doing anything that involved automating CVI via ActiveX, were you?

Thanks,

Luis

I do have 8.5.0.279 and was not automating CVI with ActiveX.  I do not know what sequence caused the crash since it does not seem to happen after I do anything in particular.  It does not happen that regularly, maybe once or twice a day under heavy use.

Ok, could you have been generating a function panel from an include file?
