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??

Then when you acquire with the frame grabber, the acquired image will

By my understanding, compact field point need LabVIEW real time. My
question is: Does LabVIEW real time have the same function as the
desktop LabVIEW? For Example, LabVIEW PDA module has less function
than the desktop LabVIEW.
Yes you have the same functionality as LV. You can develop like
normally in LV and then you will target a real time system. This will
then download the vi that you created and allow you to run this vi on
...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.

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 126.96.36.19905.

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 !

I am attempting to write load cell, linear transducer and time stamp to EXCEL. Due to the limited room in EXCEL I have a sample rate of 10/second. This is accomplished by setting the DAQ assistant to one sample (HW timed) in the acquisition mode of the task timer. A wait timer set at a loop rate of 1000 millaseconds is included in the "while" loop to slow the sampling rate down. This works well. Now the data is taken outside of the loop and entered into a "build array" block and then into a "write to spreadsheet" block.

I am running LV8.5. I am upgrading and/or converting an old legacy system. All I have is the disk with the VIs from the old system. I do not have an older version of LV installed.
I can install all the way back to version 5.1. But I am concerned, can LV8.5 convert 5.1? The real question is what is the earliest version of LV that 8.5 will convert and will that version convert 4.0.1?
I have to imagine this has been done. With all the legacy systems going obsolete. This should be a common need.
Thanks for all of the responses. I have about 500+ VIs to convert. I would not be able to post them because of the nature of the projet but thanks for the suggestion. I have to imagine that someone in the office has 8.2 still floating around. I do not want to go back to 6 or 7. I will hunt for an older machine in the AM. Maybe a good job for an intern.

I made drivers for some thrid party instruments, which is compatable for serial port and Ethernet. I have several vi's for that i cant able to share these vi's to my friends.
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...

...Driver paths in Labview no DAQ Assist
Hello, I am new to LabView and I recently installed the student edittion of Labview 8.5. For some unknown, crazy reason i did not install this to the default drive path, ie C:program files\ etc but to another drive on the computer, ie E:.Now the problem is that i need to use the DAQ Assistant for my USB-6008 board. I have installed the the NI drivers which came with it and the board works fine in MAX, recognises it and i can get temp readings from the circuit i built. When I try to use Labview I cannot find the DAQ Assist in the Input section on the palette.Could some please help me. My mate gave me a file he did on his Labview but when i try to load it starts looking for DABmx Control Task and a whole host of other files.Much appreaciated for any help in this matter.Lee
Its cool to install things into different places on your drive - sometimes its essential. there is also an easy solution to your problem. What you have at the moment is different drivers and programs spread around your computer with no links to each other so they are unable to reference each other. To create these links yopu will need to mass compile.
Within LabVIEW go to the tools menu and then select Advanced>>Mass compile. This will bring up a window that will allow you to select a directory. Select the directory that you have saved all your DAQmx drivers and then select mass compile.
This should allow you to see all the VIs in the correct menus within labVIEW.

First of all I?m new to labview, so excuse me if I?m not putting this right, but I?m trying to explained as much I can.
I build a K8055 board. Basically its some kind of I/O board that can be connected to the PC through a USB port. The board is provided with VB demo application and a DLL file that can be called to communicate with the board.
I started creating VI to run the board using CALL LIBRARY FUNCTION so it can read/write to the board. So far I managed to initial the connection to the board, read the analogue inputs and write to the digital outputs. The problem is that the VI takes a long time to execute the functions while it?s executed instantly in VB application.
Any information would help me to build this application right would be appreciated
