Labview 7 crashes when opening an earlier Labview version VI
Hello guys. I am using Labview 7 professional edition. The labview crashes when opening an earlier labview version VI. The error message I'm getting is just "Labview has encounted a problem and eneds to close. We are sorry for the inconvenience." The VI contains a few Tag SubVIs, and It is written with an earlier version of Labview(BridgeView is what it was called).
Do anyone have any ideas that how I can fix this bug? It's going to be a great help. Thank you very much.
LabVIEW should not be crashing in this situation. Now, does this happen for other simil...opening a labview 8.5 file with labview 8.21
Hello,I was working on a project at home with labview 8.21, I nearly finished this project but I addes some stuff at school where they have labview 8.5.Today I wanted to open the labview file on my computer, but It gave an error:
labview load error 9: Vi version 8.5 is newer then labVIEW version 8.2.1.Is there any way I can open the file on my computer?Or can I save the file at school als a 8.2.1 file?
thnx in advance,Seppe
Hi Seppe, just save it in school using "Save to previous" from the file menu...
You'll have to reopen the file on a computer with LV 8.5. From there you can do a Save as Previous Version to save back to LV 8.2.1
Hi Seppe, if you have LabView 8.5 you can save your vi for previous verions (8.2.1 and 8.0)Mike
ok, thnx for all the correct answers !

It is not possible directly. Somebody with access to version 8.5 needs to save it for version 8.2.
Could you attach that particular vi in your post so that somebody can save it for 8.2
Or you can install Labview 8.5 demo. Works for 30 days....

I have a collection of programs written in LabView 4. I upgraded to
LabView 7 recently. I am now trying to open my old 4 vi's with no
luck. No block diagram is the error that I'm getting. Any ideas on
converting would be greatly appreciated.
Without a block diagram, you cannot open a VI in a newer version
because the block diagram is required for the recompile. The only way
to upgrade is to find the original VIs with the source code. No one,
NI included, can recover a block diagram once it has been deleted.

...Re: LabVIEW and LabVIEW RT?
I will try to illustrate it with an example since it all will depend on the type of application you would like to implement. Let's say you would like to implement an application where you log data, maybe exchange data with databases and you acquire a bunch of data points at a time not performing any type of control and where high determinism is not needed. In this case LabVIEW for Windows work great. If you on the other hand would like to implement a closed-loop application where you need high determinism and reliability and will acquire data point by point you would use LabVIEW RT which is an add-on to LabVIEW. I.e. you need LabVIEW + LabVIEW RT when developing an RT application.
...Time in LabVIEW DAQ Assistant and Write LabVIEW file
I would be extremely grateful for your assistance in helping me understand the timing in LabVIEW.
Here are the details of the system. The data acquisition is done using a simple LabVIEW 8.2 based program consisting of a DAQ Assistant VI and a Write to Measurement File VI, which writes data in TDM format (binary with XML header).
The hardware consists of a 1042Q chassis that contains 2 PXI-6133 cards. 16 transducers are connected to these 8 channel cards. The chassis is connected to a PC by means of MXI-4 fiber optic cable and a PCI-8336 card.
I would like to sample all 16 channels simultaneously at 500 kS/s for 2 secs. or 1MS/s for 0.5 secs.
When the signals were sampled at 500kS/s x 2secs., the time column looks like this when opened on DIAdem.

...Unable to install labview in the new mac using the 'labview CD for Power Mac'
I have got a 'Labview full development system for power macintosh'. I have to use labview for some application and so I tried installing labview in my imac using this CD. The CD gets ejected out by itself. I tried it in a Mac laptop. There it opened, but when I try to install it, it gave the following message: 'You can't open the application 'Install Labview' because the classic environment is no longer supported'. Please note that the macs that I used are Intel based. What is the cause of this problem? What is the solution?The version of the software is : 6.0Please do the needful.Thankyou,Pavithra Souriraj
The version you are trying to install was apparently written for Mac OS 9 or earlier, hence the reference to the Classic environment. The Classic environment is an emulation of OS 9 under OS X. However, Apple did not start using Intel processors until several years after the introduction of OS X, so they (Apple) did not develop an OS 9 emulator which will run on Intel based Macs. You cannot run LV 6 on an Intel based Mac. This is an Apple issue, not a National Instruments issue. LV 6 runs fine under OS X on a PowerPC Mac, as do several other versions.You will either need to get an older Mac or a newer version of LV. I am not sure which is the earliest version which will run on an Intel Mac.LynnUsing LV on the Mac since version 1.2

...Labview 8 crashes when using Read Labview Measurement File
I am a new user for Labview. I installed Labview 8.0 from the CD (evaluation copy). I was just testing the sample code provided by NI. I opened the "Load from File and Display" example and I was trying to open the properties for the Read Labview Measurement File component when Labview crashed. I tried it a couple of times and everytime it happens the same way (when I double click the component or right click on it).
I am using Windows XP with all the updates done. In the Windows crash report, the application version is 220.127.116.1105.
Other problem ...LabVIEW 8 does not close ref's the same as LabVIEW 7!?!
I have been struggling with a difference between LabVIEW 7 and 8 in how the Close Reference functions for Active X objects. In order to fully understand the problem, let me first explain the process of how I got here.
I have an application in beta testing and we noticed a huge memory leak in LabVIEW 8, 8.2. I took a snippet of the code and worked on it a while to reduce the memory leak. I was closing every reference and could not explain it so I wrote the same code in VB and saw no memory leaks. I implemented the same code in LabVIEW 8 and still saw a memory leak. The code opens a graph control from a third party vendor and draws it. Each time the graph is drawn in LabVIEW 8, it costs about 30-40k. We have 8 graphs in our application bringing each iteration to 240-320k. The users are going to be reviewing between 96-384 samples in one sitting but we have no control over when the program quits. 384 samples reviewed in the graphs is 92,160k as a minimum. I was frustrated and about to send it to the thrid party vendor, AB Sciex, but they only had LabVIEW 7.1. So I converted it back to 8.0 and then to 7.1.1. I ran the code in 7.1.1 and there were little to no memory leaks! I even tried it in LabVIEW 7.0 and it worked the same as 7.1.1.
I monitored the memory of LabVIEW through the task monitor in Windows XP. I have tried it on a few XP machines and a 2000 machine and same answer on all. I also built a Task Monitor tool using .NET to graph the memory of the LabVIEW proce...How do you read old Macintosh LabView files in LabView 6.1 for the PC?

We have several versions of labview running different test and control functions in our facility. There are labview 7.2 VIs in a production setting I wish to reproduce in the test lab. Can I convert them to run on 8.2 or do I have to recreate them in 8.2. I tried to open one in 8.2 and got multiple SubVI's that were not in my program library.. most dealing with AI manipulation.
And make sure you have backup copies of your 7.x code. Once you load and save in 8.2, it is a lot of work to get them back to 7.x.
Note I used 7.x because I am unaware of LabVIEW version 7.2 even existing. 7.1.1 was the last release prior to 8.0
...Re: "Total Data Size" property of running VI in LabVIEW 7.1 doesn't work any more?
Just bumped into this problem and did find the answer in this thread dating back to 2005. So, is there a way to do this with 7.1 or 7.1.1 or not?
From the 2005 discussion, the resolution was that in LabVIEW 7.1 and later, you cannot read the memory used by a running VI.
I just ran both example programs posted in 2005, and no - you still cannot read the Total Data Size of a VI when it is running. I ran both programs in LabVIEW 8.5.1.

So, how does one debug potential memory leaks or fragmentations?We have about 2700 VIs written by four or five people, part of two or three "top-level" VIs we call over and over again, and a very small leak, as far as I can tell by the rate of increase in the execution time and program size/memory/handles. These are all part of an LV executable we call remotely through a crude TCP interface at the rate of 25k calls per month. We don't even have LV on that machine.There's got to be a way to find out where the problem is that doesn't imply staring at every single of those VIs. And divide and conquer is a bit hard at this point, given the amount of code and associated instrumentation.
I will investigate your options and respond shortly.

i just want to build one package of my driver, also i want to install these package to labview user library.
Tell me some good suggestion for this.
With warm regards,
The easiest way is to do a development distribution (File>>Save As.
If your needs are more complex, you can also try <a href="http://jkisoft.com/vipm/" target="_blank">VIPM</a>. I don't think the free version can do this, but it's worth it just for getting the OpenG code.
where i can find this development distribution ? is there option available in labview?
If you re using LV versions > 7.x, you can create an LLB by using the option Save As... in the Files menu.
You have to just open the top-level VI of that driver (or something) & go on to build the LLB. All other VIs will get added/bundled into it automatically. :smileyhappy:
In LV 7.x, I think it ll be under the Tools >> Build Source Distribution menu...

...Save VI developed in Labview 6.1 to work in Labview 5.1
I have been working with Labview 6.1 but I need to execute my VIs in
Labview 5.1 too. What can I do to reuse all the VIs without having to
develop them again in Labview 5.1? I am not able to save my VIs as 5.1
from Labview 6.1 It only allows me to save them as Labview 6.0
Assuming they can be converted, and there's not too many, you might
want to try posting them here for someone to convert. (convert to 6.0
first and zip) Not too elegant but may get you out of a bind.
Yes, each new version of LabVIEW only carries the capability to save
for one version previous. So, you would need to save the 6.1 VIs for
vesion 6.0, and then from LabVIEW 6.0 save for 5.1. If there aren't
too many VIs, one of our engineers here would most likely have no
problem with making the conversion for you. You could email NI with
them to make it more private, if you'd like, rather than posting them
on the site. (To create an email request, go to www.ni.com/ask).
Hope this helps!
