SOS! Traped in a while loop, need to stop VI right now without quiting LabVIEW

[BryanL]

This is embarrassing! I have many VIs open on my desk top and made changes to them. Then for a break I decide to play with two while loops and wanted to see their behavior...that is when I got traped.  (I was trying to see if the inside loop can be stoped when the outside loop is stoped).  Now I cant stop this VI  without terminating LabVIEW.  If I terminate LV, I will loss all the work on my other VIs which didnt got saved. Is there a graceful way to get out of this trap? Please see the attached VI.

Thanks.

The vi abort button (red circle) doesn't work?

• Upgrade to LabVIEW 8.x
  
• ctrl-.
• ctrl-alt-delete (on win), terminate LabVIEW, LabVIEW might respond, with a pop-up, where you can select cancel to overrule the closing but stop the VIs

Just tried it while running your vi, hold down the escape button (to close the popup window) and keep clicking the abort button,it'll stop eventually.

1. Move cursor over the Button on the popup.
2. hold down "ctrl"...
3. hold down "."...
4. While 2 and 3....
5. click mouse button a few times until VI stops. (you might need to try a few times)

tried Altenbach's solution and worked right away for me..

Troy's solution worked within 5 - 10 sec.

These are tricks worth knowing!  Maybe a tiny nugget out of these 😉

This is all too much a common problem, especially with cfaster loops they are hard to break into.  Another common problem is when you leave modal subvis opened then you get stuck when you run.  WHY DOESNT NI HAVE ITS OWN BUILT IN TASK MANAGER.  I wrote one a while back and it saves me all the time.  Essentially you get a list of references to all opened running vi in memory and allow the user to stop eny of them.

Hi All, thank you so much for offering your tricks and sharing your thoughts. I tried with Troy's method, it worked very quickly. I agree with Paul it will really help if NI can provide us a LabVIEW task manager. For now, your tricks made the biggest difference. Thanks again.

Or you can just write one yourself. Attached is a very quick example. If you build it into an exe and enable TCP access in your VI server, it should connect to LabVIEW. You might need to give the exe a different VI server port than the default.

Here's one I was playing around with.

The only problem is that it won't jump in front of a modal window (message box for example).

So it's useless to stop BryanL's while loop vi (aka LabVIEW version of a chinese finger trap).
