...labview 8.5 to labview 7.0
i am on my labview working with 8.5but at work, we only have labview 7.0.what would be my best way to get my vi to be 7.0?thank you so muchMessage Edited by krispiekream on 06-19-2008 03:59 PM
In order to go from LV 8.5 to LV 7, you will need to have LV 8.5 (save it back to 8.0), LV 8.0 (save it back to 7.1) and LV 7.1 (to save back to 7.0).
If it's only a few small VI's, you can post them on the forum and ask someone to do the saves for you. (Best if you do the save back to 8.0 and post that in order to eliminate 1 of the 3 steps for whoever will do the rest of the conversions for you.)
yeah. great.. i did all those steps.i went from 8.0 to 7.1i dont have labview 7.1 so i can't go to 7.0.can someone please help me.
Please try the attached to see if it works with LV7.0
Hopefully it does!!
thank you so much. i'll try it right now.
hi there,i somewhat got it to work.but i am having this error everytime i try to save it.does anyone know how i can get rid of it?<img src="http://forums.ni.com/attachments/ni/170/334653/1/untitled5.PNG"> Message Edited by krispiekream on 06-24-2008 06:02 PM

Hi again :)
I have a cRIO system that is running Labview 7. It runs fine. No problems. We've upgraded to LV8 and I'm wondering if I should convert the LV7 system to LV8. The only reason I would do this is because for me LV8 is much easier to work with regarding cRIO (using DMA, setting up the project etc.).
Now, if I attempt to upgrade the LV7 cRIO system, what kinds of problems will I run in to? I assume it means formatting the cRIO, installing LV8, converting the program from LV7 to LV8...
Is there an FAQ regarding this, specifically about the cRIO?

I have a probelm when I use the "tool/import shared library(.dll)" wizard to generate the API from C.
The API works correctly when I complete the wizard, but after I exit labview and re-start labview to run the API again. The error 1097 code "......this might corrupted LABVIEW's memory.............."appears.
The only solution now is to re-generate or update the wizard to generate the API.

Hello, For a independent study Labview class I'm taking, I am trying to create a program that will input two different wav files and combine parts of them together for audio output. The first file I am trying to cut out the bass lines and replace them with the bass lines from the second file. Kind of like turning the second file into a karaoke version and filling in the vocals with the vocal line from the first file. A second option is simply taking the instrumentals from a song (a wav file containing only the bass line) and adding them to the first file after cutting out the original bass line of the first if this isn't possible. I found the attached file while searching for information/examples as to how to do this - it was originally posted at:http://forums.ni.com/ni/board/message?board.id=170&message.id=74618&requireLogin=FalseI tried running the file in Labview 8.20 and it came back with the error that "Build Screen.vi not found." I have searched for this file to download but have come up with nothing.Also, any tips/pointers/comments (or "there is no way this is possible") are much appreciated and very welcome. I have been searching to see if there is anything like this that has been done before and as of yet haven't been able to find anything. I am pretty new to Labview but I am a quick learner and I have a professor working with me on the project that is very familiar with Labview. However, it's spring break right no...If i have a labview .vi file(and labview) but i want to open it in a computer that doesn't have labview, how would i do it??
Okay, i have a made a labview program and save it as.vi.
Let's say that it is a program that when opened and you hit run it shows a sine wave.
Now if i wanted to open up the program without Labview, ( i don't need to modify it) on a computer that doesn't have labview. How would i go about doing this??
...How can I run a labview 7.2 vi in labview 8.2
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
...Why multihreaded soft worked under Labview 7 but is slower under Labview 8.2.1
Hello all !
I have a multithreated software developped under Labview 7.0.
Under this version, multithreading can be enabled/disabled via the options menu / performance & disk section. This is not present under Labview 8.2.1.
My software works properly under LW7 but is slower under LW8.2.1...how can I configure labview and or my vi to make it running as well as under LW7 ???
Is there a "hidden" option to enable/disable multithreading under LW8.2.1 ?
Thank you for your help
To disable multithreading, add ESys.StdNParallel=0 to the ini file.
(See: <a href="http://digital.ni.com/public.nsf/websearch/2F606AD236C606008625718E00561A62?OpenDocument" target="_blank">http://digital.ni.com/public.nsf/websearch/2F606AD236C606008625718E00561A62?OpenDocument</a>)
However, it is not celar that this is the problem. Did you save the entire hierachy under 8.2.1 after conversion (of course after making sutable backup copines of the 7.0 version ;)). Freshly converted, but not yet saved code runs typically much slower.
Also, what do you mean by "slower" 10% slower, 10x slower? How do you measure speed?
Thanks for your quick answer altenbach.
The tips given at this link will really be useful to me!
It seems that I made a wrong conversion of the files...fortunately I made suitable backup of the 7.0 version :smileywink:. I will investigate mor....net return type different on LabView version 7.1 v's 8.20
I'm trying to communicate with an external API from within Labview.
The atttached doc shows the problem i'm seeing. When write this vi in Labview version 7.1, 'accessLevel' is returned as a refnum. When I write the same vi in version 8.20 'accessLevel' is returned as a string (correct).
Is there a way to return the correct data type in version 7.1?
Thanks for the tips! I'm using Net 2.0 so I'll try the 7.1.1 patch you recommend. When I wire the refnum to an invoke node there are no methods available so no luck there. I'll let you know if the patch works out.
...Would a LabVIEW 8.5 Executable play nice with LabVIEW 7.1 Development on the Same System?
Our testing computer right now just has the user run the corresponding .vi file since we have LabVIEW 7.1 installed on the computer.
If I use 8.5 to compile this .vi to an executable, I realize that I must install the run-time support for 8.5. My question is what effect will installing the 8.5 run-time have on the ability to continue to run the other 7.1 VIs with LabVIEW 7.1.
Should I be concerned with losing MAX settings when installing the run-time support for 8.5? I want to be able to run 8.5 executables but also able to open up a 7.1 .vi file in LabVIEW 7.1 and run it that way also.
Thanks for your help! I have 8.5 on my system and the idea is to slowly replace the running of the .vi files with .exe files, I was just curious in case my .exe doesn't work I can still run the tests with .vi in the mean time.
Thanks for your help folks!
...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 !
...labview 8.2 llb run with labview 8.5
On the PC I have delete labview 8.2, but I dont find the CD for reinstall. I have a .llb file made with labview 8.2, Can i run it with labview 8.5 or download labview 8.2, I muss install ii rapidelly.
Costello, you can update the VIs within the LLB to LV 8.5 if they do not have their blockdiagram removed.....hope this helps,Norbert
How can I update ? When I start the .vi in the lbb he dont found somme .vi located in DAQmx (wrtie.lbb, start task.lbb,...) How can i install this lbb?
Costello, if you get loading errors when opening one VI from the LLB like you the ones you get, you have missing components.Since you spoke of DAQmx, i asume that you didn't install NI DAQmx on your machine. You should catch that up.hope this helps,Norbert

Good afternoon everybody,
I've got a big problem with LabView. The fact is that I begin with this software...
I've just installed LabView 8 on a computer where LabView 6 was installed. Once the installation finished, I tried to launch a VI That was developped under the old version.
The problem is that two VI can't be found :
- AI Sample Channel.vi
- AI Acquire Waveform.vi
Therefore, I can't use anymore the program that was working before... What is the solution to get everything ok please ?
Thank you very much !
the VI will now...How can I get handle(s) to and poll non-LabVIEW window(s)/application(s) from LabVIEW?
Want to launch EXE from LabVIEW, wait for user to finish with EXE's UI, and once they closed it, return execution flow in LabVIEW. Cool, no problem.
Used the System Exec VI and with the "wait until completion" = TRUE the EXE never launches. Not sure why.
With the "wait until completion" = FALSE, the application runs with no problems, but now LabVIEW no longer waits. Can't tell when user is done.
Work around idea... Once the Sys Exec VI launches the EXE, wait and poll some Windows API call to see when the window for the specific EXE closes. Cool.
I know G and no C. What I would ideally like is a DLL, that I can wrap with the DLL Import Wizard. Of course best would be a VI and the wrapped API call.
You could try it with a pipe. With a pipe you can open an exe, and interact
with it through a read and write reference. Although in your case the exe
might not start, since the normal sysexec doesn't start it...
...Integration of two different labview infinity projects and how to import labview's calcutation into flash animation
1) I have a labview project for strength gauge using flex sensor and another labview project on tracking the brightest light intensity of image captured by webcam.
How do i integrate both together?
2) How do I show simple animations of the measurement result?
For e.g if I am doing a measurement and position tracking of a bow and arrow game using labview program,
how do i show the bulleye's and whether the user has hit on the bull's eye?
Is it possible to import flash animation of the bull's eye? How do i do that?
this may be an solution for your first question.
the project file of LabVIEW is a XML file.
you can open it with a txt editor, such as notepad, ultraedit, and so on.
or a XML editor is prefer.
then try to integrate (copy and paste) the part of the content two project.
it maybe works. i think.

Since LabVIEW 8.5.1 is only a bug fix, can LabVIEW 8.5 read any VIs generated in LabVIEW 8.5.1?
Simple answer YES. But it will the VIs compile so it is a good idea to make a mass compile in the folder where the VIs are.
...LabVIEW 8.0 changed a constant that was wired to a Case structure to a hidden control to maintain compatibility with LabVIEW 7.1 and earlier.
Y am i getting this msg?
This happened because "...LabVIEW does not compile code on the block diagram that does not execute. For example, LabVIEW does not compile any code that exists within the inactive subdiagrams of the Conditional Disable structure. In addition, LabVIEW does not compile code within a Case structure that has a constant wired to it that would not execute the case with the code..."In the other words, if you have case structure, which is wired to T/F constant, then prior to version 8.x both cases will be compiled. From version 8.x the only "executed" case will be compiled. So, LabVIEW replaces constant with control for ensure that both cases will be compiled as before.

...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
