LabVIEW
Can't open a VI
Not getting the dialog at all is a little strange. My guess would be the VI is damaged. If that's the case, not much you can do except try to find it again.

Thanks Ed, I already knew this. But generally we get at least a warning message.
In this particular case, I was almost sure the vi was 8.0, because the author said it contained MathScript nodes (my attempt to open it was a programatically hopeless action, just to be able to say "I tried anyway"), but if we don't know the actual version of a vi we are trying to open and we get nothing, there seem to be two possibility open: wrong version? vi damaged? Boh!? (Boh!? is an Italian way to say "who knows?")

You might actually want to submit that VI to NI through the support request page so they can try and investigate what's going on with it.

Using the Abort button to stop your VI is like using a tree to stop your car. It works, but there may be consequences.
Since you didn't purposly save it without the diagrams, then something must have happened during the regular Save process that damaged the VI. If you don't have recent backup, you're stuck starting over.

Dear Ed,
I don't know how I did to not save the block diagram, I've already saved a lot of VI and I've never had this problem...
But thank you for you answer.
This is a good time to remind everybody to always keep daily backups. Even if it's just a mirror copy of your projects to a second location on your hard drive. There's a few free backup and sync tools that I use for this.
One is called TreeComp. This let's you manually sync directories either loaclly or across a network or to an FTP site and even into a Zip file.
Another is called Back2Zip. This is a system tray application that you setup to automatically backup directories you specify. It can keep numerous dated copies so you can go back several versions if needed and can backup to standard Zip files.
A new one I've been playing with is from Microsoft called Sync Toy. Basically the same as the Back2Zip. Not sure which on I like better, but I'm leaning towards the Back2Zip.

Hi Ed,
very often I don't get a message from LV7.1 when trying to open a LV8-vi. It seems to do nothing when "opening" such vi's... But LV8 opens those vi's without any problems.
But the vi from carolyne still is broken (as said by you earlier).
