Unable to unlock VI with VI properties or view block diagram.

[dcorrigan]

I have a VI that I need to modify, but I am unable to open the block diagram or unlock the VI in the VI properties dialog box (options are grayed out).  I generally have my VIs locked with no password, but I have always been able to unlock them at a later time with the properties diolog box and change anything.

Is there a way I could have locked myself out?

If you saved the VI without a block diagram, I believe this could happen.  If that is indeed the case, you'll need to replace the VI with your latest backup, since there's no way to retrieve the diagram once you've saved a VI without a block diagram.

Also, make sure you're not trying to look at the diagram of a Control or Global VI... 🙂

I was afraid of that.  Not the good news I was looking for, but thanks for the info.

Maybe this will help someone.

I had my computer idle for a while, and when I resumed work. I noticed a dialog box offering to restore crashed items.  I dismissed it because I save my work frequently.  Then, I noticed one of the vi I had been working on was locked -- the Protection status was locked (no password) and greyed out.  I went and found the autosaved item that LabVIEW created in folder: LVAutoSave/archives, which was good with the block diagram available to open.  wheew...
