Labview crashed when saving vi and now cannot open VI libray

[Ashley.w]

Hi

I am using LabVIEW 7.1.

I am developing a moderately large application.  I Just saved my main VI and LabVIEW crashed for some reason.

My vi library will now not open.  When I try to open the library I get the error message: "an error occured when listing the contents of (my directory/myvi.library)".

Has anybody ever had this problem and if so does anybody know how I can recover my vi library?

I have just lost about 2 days work so if anybody has any ideas I would be most grateful.

I hope it is not a fatal problem - I cannot even show the vi's in the vi libray using windows explorer.

Many thanks

Ashley

It looks like you've learned the hard way why you should not use .llb's during development. If a single VI in the library get's corrupted, the entire library is bad. This is why during development, you're much better off keeping everything in an organized directory structure. This way, a crash like you had would only affect those VI's that had not yet ben saved.

I've heard rumors that NI has an internal untility that might be able to recover the library. I'd try contacting support directly to see if they can help.

Good Luck

Many people have had this problem and that is why you should never do development work with an llb. An llb should only be used to distribute a project. Your only option is to post the llb or submit it straight to NI support and see what can be recovered by them. In the future, keep your VIs in a folder or backup much more often. If you have any other llbs that you use for development, you can use the VI Library Manager to convert an llb to a directory.

Hi Dennis and Ed

Thanks for your replies

I have a back-ups of all the sub vi's and a very rough version of the application.   I will just have to start again with what I've got.  I was very stupid - and will have to  take the wrap.  Better update my resume!

Cheers
