The strangest problem I've ever seen


Recommended Posts

Good morning,

I am a Labview developper and I have the most strange problem I've ever seen.

I have developped a Labview software that I compiled in exe.

I compiled an installer. For now, no problem.

I install my program and it works.

Unfortunately, something happen randomly:

My program freeze. I examine task manager, no CPU overload, no memory overload.

I click on the front panel (whatever where i click) and in continues what it does.

Sometimes later, it freeze again, i click again on the front panel, it continues.

Can you help me?

I've seen that happening in the past with some application a few times. Not sure what was the fix as it is quite some time ago and involved an ancient LabVIEW version. I guess moving up to a newer LabVIEW version was the fix for that for me.

What was your Labview version when this problem happened to you?

I am actually in LBV 8.6.1

Do I have to evolve to LBV2009?

There was an issue where opening a menu and leaving it open (or any number of other actions) would block a vital component of LabVIEW known as the "root loop", which would cause behavior of this type.

I have no idea if this is what's happening in your case, but if it is, then presumably clicking in the FP will close the menu, thus releasing the root loop.

No this was definitely something like LabVIEW 6 or even earlier. With ancient I did mean ancient! laugh.gif

I haven't even started to do real project work in LabVIEW 2009 yet.

... and I thought I was a stick in the mud.rolleyes.gif

As a regular user of the Hierachy screen, the changes that were added in LV 2009 are really nice. Is this a self-imposed exercise in discipline?

I found another symptom.

My program was frozen and I still had a USB key connected to the computer. I disconnected it without safely remove via Windows. The program resume after that.

:wacko: :wacko: :wacko: :wacko:

I continue to investigate.
