LabVIEW
LV 8.6 code not upgrading to 2009
I'm not exactly sure why this is happening as I was able to successfully upgrade this code on a Windows 7 machine. But on the XP machine I used to originally develop it, the upgrade to 2009 isn't working.
Something is breaking in the event structure.
What I want to ask is; Is there any way I might recover from this?
My Event structure has no Event 0. That should be my Timeout case. A bunch of stuff is messed up in the event structure now, and I don't think I can fix it.
Suggestions most welcome.
Thanks for the reply.
It appears that what happened was that my LV 2009 installation broke on my XP machine.
I had SP1 installed. But I installed an educational version over that as I was doing some playing around with a Lego Mindstorms brick.
My splash screen for LV 2009 changed. But at first everything seemed fine.
Then I did some work on a large project and I noticed the event structure was messed up.
I had actually tried saving the code on the Win7 and opening in it on the XP machine. It was still messed up though. But I don't think it had anything to do the version.
I found that even with a new VI my event structure was messed up. So I uninstalled LV and reinstalled. I've still got the educational splash screen. But things do seem to be working.
However, I've got a looming problem possibly related to this.
The large project I was attempting to migrate to a new version of LabVIEW and Windows is now acting erratically at the customer's site. At first we found that the NI-DNET drivers that came with the 2010 SSP disks was not Win7 compatible. There was a new driver online, and we had hoped that would solve the intermittent IO problems we'd been seeing.
Unfortunately the phone call I got first thing this morning was that customer telling me the machine is getting, "Worse and worse." Indicators are stating that equipment has been shut off, but the equipment is actually still running. Apparently it's been doing this for a few days now, but is progressively getting more noticeable as time goes on.
Also, if anyone knows how to make sure the NI update services is completely turned off.....I would really like to know. I'm quite sure I turned it off on this customer's machine. But it keeps popping up and confusing the operators.
The worst part is that my customer has now completely lost confidence in the upgrade. There's too much riding on this system working, so a decision has been made to downgrade the new PCs OS back to XP and scrap any new work done on the code in LV 2009SP1 and return to 8.6
I would like to hear from anyone using the NI-DNET drivers either with LV2009 or LV2010 on Win7
This is a large and ongoing project for us and I would really like to keep the code current. Unfortunately down-time is not an option at the moment.
