LabView Can't save VI

I'm trying to save A vi in a project and keep getting the message
LABVIEW: An input parameter is invalid
save error code 0
there doesn't seem to be any reason why it can't be saved.

Hi there!
I am having the same issue when trying to save a VI.
I will respond the questions posted by smercurio_fc (answers in red):
Are you trying to save to a network drive? If so, save to a local directory. [answer]: NO, I am saving to local disk.
Are you trying to save to a path that has too many characters? Operating systems have limits on the lengths of paths. [answer]: Other VIs with longer names in the same directory do not present this problem, so I consider the path name lenght is not the problem.
Are you trying to save to folder with restricted permissions? E.g. on Windows Vista and 7 you are not allowed to save to certain directories without admin rights.[answer]:Nope.
Can you save the VI if you open it by itself, without opening the project?[answer]:No.
Can you do a Save As?[answer]:No.
Open your most recent backup and see if you can save that. It's possible your VI has become corrupt.[answer]:same problem.
What changes are you making that's prompting the save? Or, is it prompting you to save simply by opening the VI?[answer]:I have onlu opened the VI.
Are you calling subVIs? Can those be saved OK?[answer]:Yes and they can be saved normally.
Since you posted in this thread, I assume that your error message is still:
"LABVIEW: An input parameter is invalid | save error code 0"
Is this correct?
At what point do you get that message exactly (right after trying the menu entry? after entering a file name?)
Are the "save" and "save as" menu entries greyed out?
What is your LabVIEW version?
Does the file name contain any unusual characters?
Can you attach your VI?

    Hello,
    This VI contains components that changed between versions 8.0 and 7.1, so a Save for Previous operation will not be straightforward.  Instead, here is the block diagram so you can build it:
    Part 1 (left side):
    Part 2 (right side):
    The Hanning window function will look different but should have the same interface.

  • How can I save the modulation I apply to an instrument during recording such that it remains during playback?

    How can I save the modulation I apply to an instrument during recording such that it remains during playback? For example, I apply modulation #8 during recording, but when I play the track back the modulation is not incorporated.

    Hi Vlad,
    Unfortunately, I don't think there is a way to programmatically read the voltage output to the drive, as the voltage is all determined internally by the controller circuitry on the board. Depending on the controller though, you may be able to physically route the output terminal to a spare analog input channel and read in the voltage that way. This example Analog Input with 73xx Motion Card shows you how to program LabVIEW to do this. 

  • How can I save an EXE front panel image to a file?

    The methods to save a VI front panel image to a file don't work on executable applications. How can I save an EXE front panel image to a file? (LabVIEW 6.1)

    Hi,
    i wrote some vi that save FP to image and created exe and it works fine. How do you save FP to image in VI?
    If you use VI server method "Get Panel Image" and use "Write JPG file" ( or BPM) it works fine.

  • How can I save my configuration in my program?

    I have a VME-MXI-2and two VME devices.
    1、I use MAX configuration them.
    2、I run resource manager.
    3、set up the visa resource name in labview
    4、I read form and write these VME devices with labview programming.
    but when I run the programming next,I must repeat 2,3,4 step,why?
    Can I save these sets in labview? and I run labview programming directly,then I access the VME devices.

    Hello,
    You should never have to run Resource Manager more than once between runs of your devices. Usually, if you run Resman more than once without powering down the hardware, the devices will not respond correctly. You also said that each time you have to set up another VISA resource name each time? You should create your VME profile once and use that name from there on out, is that what you are doing?

  • How can I make a waveform graph store the entire wave, not just the current time period and how can I save the actual graph?

    I am taking temp readings with a 4 channel DAQ, sending them to a waveform graph and exporting the data to excel, how do I manipulate the graph to take a continuous reading as opposed to losing the previous GUI and how can I save the entire graph?
    Using LabVIEW 2011 operating on Windows 7 professional. 

    That is the nature of the chart -- everything not in the history is lost (it is a FIFO buffer of length=1024 samples by default).
    The scroll bar is probably grayed out because you're show all of the data.
    Attached is a program that will add 5 random points to a graph and prompt you for a file location where to save a JPG snapshot of the graph.  It's not particularly good programming style, but it has all of the elements/concepts you're after.

  • Hi..I really don't understand how can labview can be a server, can you explain and give me some examples with steps on how to make the labview as a server? Please......

    nn
    Solved!
    Go to Solution.

    erm ok i will explain...
    actually..i know that labview can be a client or server. when the labview be a client, it can access other enable activeX application such as excel or word. i manage to do that a little such as to open excel file and save it at another location by using activeX functions or using the report generation toolkit. yes, i already know and understand the flow or concept of how the labview can be a client. But by using others activeX application especially excel, how can we make the labview be a server? i just need a very easy example and few steps for me to understand how can labview be a server or how excel can control the labview properties?
    really desperate to increase new knowledge.....:-)
    thank you very much for helping me....

  • Hoe can I save 7.1 to 7.0

    hoe can I save 7.1 to 7.0. because  my other classmate do not have 7.1 ,so when I give them my code,they can not open,so I ask this question

    Use the SAVE WITH OPTIONS item in the FILE menu.
    Choose SAVE FOR PREVIOUS.
    You will lose any 7.1-only features, of course, but it will warn you.

  • How can I save to the same map every time when printing pdfs?

    How can I save to the same map every time when printing pdfs?
    Finder points to the document map even when I chose a different map recently.
    I often print series of pdfs from the print dialog box, I'd like to choose the map to save to and then have all subsequent pdf prints automatically directed to the same map until I decide otherwise.

    that link seems to be broken right now:
    403 Error - Forbidden  - No cred, dude.

  • How can I save multiple titles under the same DVD?

    I use HandBrake to rip DVD's into iTunes. How can I save multiple titles under the same DVD? For instance, I have a Jimi Hendrix documentary that comes with special features, such as concert performances. I would like to have the main feature and the special features saved in my iTunes under the same title, perhaps as different 'tracks' (kind of like how different songs can be saved under the same album).
    Is there a way for me to do this, or am I chasing phantoms?

    *This response is for iPhoto 11 (v9). If you're using an earlier version, please post back and let us know. Troubleshooting steps are not the same for different versions. To find out which iPhoto you have: iPhoto Menu -> About iPhoto)*
    Duplicate the photo first. (Photos -> Duplicate). This means that you will have multiple copies of the master as well as the edited version.
    If you use versions like this often and wish to have only one master then you can do this with Aperture.

  • We have a PC with iTunes that needs the hard drive reformatted. Right now, it can't connect to other computers on the network. Can I save my music to a thumb drive, then re-load when the computer is reformatted?

    We have a Windows XP desktop with iTunes for windows. The hard drive needs to be reformatted. Right now, the computer will not connect to other computers on the network. Can I save my iTunes songs to a thumbdrive, then re-load after reformatting?  How do I do it?

    Copy the entire iTunes folder out to the drive. If it is too big to go as one copy stuff over to another computer in batches. It is important to have not only the media but the library file in order to properly restore your library.
    See also this User Tip. Assuming the machine won't connect to the internet you could download the SyncToy installer on another machine and then transfer it with the thumb drive. If it will connect to the net don't forget to deauthorize the machine before reformatting the hard drive.
