Block diagram does not open

[girish53]

I am using Labview 2020. I inherited an old vi which I am trying to clean up. I am able to open the front panel, but it does not let me open the block diagram because there are errors in some of the subvis. Is there a way to force open the block diagram so that I can delete the non-working subvis?

Thank you.

You can get through all the missing dependency prompts by selecting stop loading in the dialog.

So you can load the VI when you see its frontpanel - but then you cannot open the block diagram because of broken subVIs???

Is this (really) the exact error message?

Here are the errors when I click on the broken arrow in the front panel

CryMOCO_ver3.vi is the main vi whose block diagram I am trying to open.

Thank you.

So you cannot execute the VI, but you asked for opening the block diagram.

What happens when you actually open the block diagram?

Exactly, I am just trying to open the block diagram, but it doesn't let me. When it do Ctrl e there is no response.

Is there a password entry that comes up when you try to view the block diagram?

I don't think the VI was saved without a block diagram because you would have to open it in the same version it was saved in then.

Could you post the VI in question so we can examine it more closely?

It is possible that the block diagram opens in an offscreen location. Does it have an entry on the task bar? If so, you can right-click...maximize, then resize it.

Yes, that was it. It created a block diagram window but did not open it. On right click when I selected Maximize it showed up. But I cannot resize it. When I click on resize-down button (top right corner) it disappears. Doesn't let me resize. Very strange. But this is progress. At least I will be able take a look at it. 

Thank you.

With the FP open, press Ctrl-E (the BD will be open, and have focus, but isn't visible because it's offscreen)

Press Alt-Shift-space.  This menu will show up:

Press M

Now use the cursor buttons to move the BD window into view.
