Open VI reference Cant find control

Unless...

From the beginning, I'm under LV2009. I open a reference to a global functional VI running on a remote computer to get the value that is in its "front panel indicator. I have two problems. The first is that when I use a string containing the name of VI, he will not find the VI. When I use the full path to the VI, the reference open VI works fine. Boring, but doable, because I have only about six FG read and they are all saved in the same folder.

Second problem and the real reason for the post: I can get all the values of control as a variants without problem using Ctrl Val. Get all the method. But when I try to name a control in the method (Ctrl Val. (Get), I get an error indicating that the control cannot be found.

SO, I used nodes property to get the text of the label and checked to see if everything was equal to the name of the command, I'm reading. It came negative. So I created a list of the labels out of the label. Property of text and node is the name I just checked for. So I copy and paste this back into the constant that is connected to the entry of the name of the control on the Val Ctrl. download Invoke node and no mistake. What the? So I delete the text I pasted in the constant and fix it and it still works very well.

I checked and rechecked enough to know that I was not typing the name in wrong, but now it works fine. I can close the VI and reopen it, works very well. Type the name again. Still works fine. Any thoughts?

An area located to the right of your constant original fits this description of the problem.

May be useful...

If you know the data type of the data that you read using the prpererty val node, you can use the node "to THE more specific" to set up your to the appropriate type. After that your val will not be a Variant, and you can use the standard LV operators to work with the data.

    A "Cannot find...". ', ' Failed to start..., "Could not load..." ». "Might not work... "" Cannot run ""error loading... ". "or"specific module could not be found"message is usually related to the malware that has been configured to run at startup, but the referenced file has been removed after a malware scan, leaving behind a registry entry pointing to a file that does not exist.
    It might be a removal of malicious software or an application not installed.  The entry may have a curious looking name since it was probably generated at random when the malware was installed.
    Windows attempts to load this file but cannot locate because the file has been deleted for most probably during a scan for malware. However, an orphaned associate of remainders of startup parameter or registry entry and tells Windows to load the file when you start or connection.
    So you should delete the referenced entry Windows stop trying to run the file. It may or may not be included in the registry.  Autoruns (see below) you get the elements no matter where it is.
    If you just locate and uncheck the item in msconfig, which disables the element but does not remove the reference to the element of false starting your computer.   Disabling in msconfig it is the old mans solution (or the profane mans solution) and leave you with a sloppy XP configuration.
    If you are comfortable editing the registry, you can search and remove the reference from where remove it using a popular third-party tool called Autoruns.
    Before making any changes to your registry by hand or with third-party tools, don't forget to first make a backup of the registry. Here is a link to a popular registry backup tool:
    Autoruns does not install anything on your computer.  It will display all startup locations where the reference may be then you can turn it off or remove it completely.  Here is the download link for Autoruns:
    Run Autoruns.exe and wait that he at the end of the filling of the list of entries.
    When the Autoruns is finished scanning your system, it will say "Ready" in the lower left corner.  Autoruns can be a little intimidating to first if you have never seen it before because it displays a lot of information.  You are really interested only a few sections.
    The problem is usually in the usually start startup entries or the system user then click on the connection tab.
    Scroll through the list and look for a boot entry associated files in the error message.
    If you can't find there, look in any tab.
    Right-click on the offending entry and choose Remove.  If you don't see it in Autoruns, you must edit the registry and remove the item from your startup folder it.  Autoruns displays the same information, however.

  • Open FPGA references change to no. target when compiled with executable in time real start

    Hello again you useful forum fans!  I have a problem that I hope someone can give me a hand with.

    I have a project that has a Windows component and a component of the target in real time, that are running on a hypervisor type NI PXI-8110 system.  Communication both sides between them using shared variables.

    On the real-time side, I have four FPGA targets who are reading and writing various analog and discrete inputs and outputs.  I several periods loops which opens a reference to one of the FPGA targets during the first call, then pass this reference in several subVIs that read and write to panels prior to the FPGA.  The loops the FPGA reference thus made available and reuse it in the next iteration through the shift registers.  Each FPGA target has only a single reference open to him.  One of the loops is using the FPGA reference directly and does not pass it in any subVIs.

    It all works very well in the development environment, I can read and control inputs and outputs FPGAS via the front panel of the application of the side Windows.  It also works very well if I start the game real time in the development environment, and run the code of windows as a stand-alone executable file.

    However, when I compile the code in real-time in an executable startup and deploy it to the target, it does not work.  I enabled debugging on the executable, and when I connect to it via the operation-> debug executable in the menu, I see an arrow broken at execution.  Further investigation shows that each of the four open screw reference FPGA is now empty, the text under them is "no target" and the thread for reference on their part to my first Subvi is broken.  I need your help to understand how to operate as it does in the development environment.

    I followed the instructions of these two knowledge base articles to compile and download the bitfiles FPGA on the FPGA target and execute on start or restart:

    http://digital.NI.com/public.nsf/allkb/39795847AC67296D862575FB0046944F

    http://digital.NI.com/public.nsf/allkb/BC513C2A0DC29C89862574BF0002B0B9?OpenDocument

    Open FPGA reference screw are configured for the FPGA to build specifications that I created for each target in the LabVIEW FPGA project.

    I called technical support, NO phone, and yet were able to determine this one out, so additional "brownie" points if you do!  I would offer you the same no detailed screenshot that I have (I can't give more detailed code out because its owner, unfortunately), but apparently the forum doesn't like my image file, as I can't seem to load.

    Please let me know if you have any ideas regarding what is happening!  I appreciate it.

    Jon,

    I'm always up for the challenge.  Have you tryied recompile the FPGA VI that accesses the RT VI?  I also suggest to try and open the bitfile instead of the FPGA VI.  You run in dynamic mode (this is not a suggestion, it's just a question)? There is no difference if you try to open the FPGA VI reference outside the while loop, then past the reference to use inside the while loop without shift registers, then close the reference to the FPGA VI outside the while loop?

    Let me know if these suggestions makes no difference.

  • Open a reference to a labview project

    I am trying to automate a database containing information on all of our bunch of labview code ancient user. I need to determine what version of labview has been used, then collect information about the screws that are part of this. I don't find a way to open a reference to a project?

    I had almost closed the window when I happened to watch again invoke the mode that made me the 'VI' Version in VI files. And it was there, under the path of the project. So simple. I must owe marewa more. Have a nice day together.

  • Bug found during the use of references to the control in subVis on Compact RIO?

    Hallo,

    I have a simple task. I want to read higher VI into a Subvi the real value of a control to a level. I want to solve this problem by using a reference to the control.

    I have attached a simplified program that shows this.

    But the problem is now. When I run the main VI on a cRIO-device, the indicator "DataByReference" is not updated with the actual value. Only when I opened during execution of the "RefMain.vi" too, then everything works fine.

    More strange thing is, when I run the VI of hand on the host PC, everything works well, also without having to open the "RefMain.vi" when executing.

    Someone at - it an explanation for this behavior?

    Thanks in advance!

    Bernd

    This isn't a bug.  See this explanation.

  • Get specific references for all controls

    Using slightly modified code from here, I'm generating a table of references of control on my main façade which is then transmitted to a number of subVIs. Although this feature does not work, it would be preferable to obtain specific references to controls (for example, Boolean RefNum instead of RefNum of control).

    Get these specific references seem possible using constants more specific class and the class specifier. However, the storage of data becomes a problem because I can use is more tables (because they are a different type of data). I don't know if there is another way to transmit these data. I experienced casting the RefNums in the variants, but to get the data of the variant, I need to know what type of RefNum I'm waiting order, of defeats the purpose of making it in the first place.

    A secondary problem is the names of references. The RefNums of control do not have names associated with them, and I do not know how to assign names to them. I tried again using variants and using the function name of the OpenG value data, but this block LabVIEW without indicating why.

    I have attached a version of my code that tries to assign names by using the name of the OpenG value data and build an array of variant. To run it, simple addition the VI as a Subvi has VI that has some Boolean controls on the front panel. My apologies for the crude State of the code - I'm still trying to find how to run things are a bit messy.

    I don't know if you're going to get much better.  There is really no way I know to have a completely flexible way to the building called cluster of references based on any set of given façade, Subscribe to this.

    I tend to do things the manual way (as there are also a bunch of references to elements of façade, that I wouldn't need).  I would like to do all the work for the grouping in a Subvi.

    I am attaching a zip file that contains the key to VI (unless I missed something) on the first project where I really tried to resume on the reference building.  The files are LV9.

    My main VI, I have the Sub - VI soon called to build the interface user of VI references during an initialization phase.  I pass the reference to the main VI in this sub - VI that generates all the references.  I worked on it as a master cluster that contains items that are arrays of references to related controls.  It uses an other sub - VI, called get references and names of labels that I created to help find witnesses.  I still need to use more specific class to get the property references, but I put only once at the beginning.  I then move this thread to cluster out and anywhere in my VI which should have access to references of the façade elements.

    I use arrays of strings to supply the names, I need to build and group references.  This allows me to ignore the controls, I don't care.  The drawbacks to my system, is that if I change the name of a command, I need to update the name in the Subvi.  And if I want to add all controls, not only do I need to add the label to search functions names, I also need to update my cluster typedef (and you absolutely want it is a typedef) to add a place to store the new reference.

    I hope that gives you some ideas.  It worked for me and I will probably use the scheme on another project (or even rewrite other projects using this diagram.)  If there are ideas of improvements, I'd be happy to hear.

  • ActiveX - Get a reference to the control

    Hi all

    I need raise a value change event in a VI ActiveX of LabVIEW interface.

    To do this, I think that I need to retrieve the reference to the control and then use the (signalling) Value property of this control.  Does anyone have any idea on how I could get the reference to a control through the ActiveX interface?

    Any other suggestions on how I can trigger a change of value programmatically event are certainly welcome.  I tried the 'SetControlValue' call function but that does not raise the value changes.

    Thank you

    Zach

    I don't know if I understand, but it looks like you are trying to control LabVIEW via its interface ActiveX from another program, such as C. In order to get the reference to a control so that you can access the value property (signs), you must first access reference front panel of the VI and then get the list commands (which is an array of references). You can walk through this table until you find the one you want, and then set the Value property (signs).

  • "Open Vi reference" error 7

    Hello

    I get "Error 7" of the vi 'Reference open VI', the name of vi is wired vi entrance road. The "error 7" means that the vi is not found. I went to "Tools ===> Options ===> paths" and changed the path so that Labview can find it. But for reasons, I do not understand the vi I want to get a reference to the was not found. So it leads me to believe that the 'open vi reference' does not use the option of path to find a vi. Any ideas what's happening?

    You use a relative path. As stated in help for the Open VI VI of reference:

    If the path is relative, the VI interprets the path as compared to appellant VI or the directory of the application, if the appellant VI is not registered.

    The search path is not used for this function. If the VI isn't in the location "in relation to appellant VI", you must provide a full path.

    Looks like you may have a virus or other malware. Get your updated antivirus program and boot into Safe Mode. Note that some viruses can hide from your normal antivirus program, so you really need to scan in Safe Mode. To enter in Safe Mode when you turn on first, press F8 on every seconds until you get the menu, and then select Safe Mode. Then run a complete system scan.

    If that suits him fine. If this is not the case, use system restore to go back to an earlier date at the beginning of the problem. To run system restore, click Start-> programs-> Accessories-> System Tools-> system restore. Click on the box that says show more restore points.

    You can check the corrupted system files. Open an administrator command prompt and run SFC if the above does not help. Click START, and then type sfc in the search box, right-click to SFC. EXE and click run as administrator. Then, from the command prompt type sfc/scannow.

    Finally if all else fails, you can look at the rather cryptic system event log. To make, click Start-> Control Panel-> administration-> event viewer tools. Once in Event Viewer system log-click and scroll entries looking for these "error" with indicator see if you can find guidance on where the problem may be.

    I hope this helps. Good luck.

    Newbe to epub creation... itunes book oven will not accept encrypted files... cant find them and which fonts can use one without this problem?

    The book oven does not accept the embedded fonts that are encrypted, even if the encryption is by the IDPF specifications.

    InDesign will not incorporate fonts unencrypted by respect for the rights of the provider of the police.

    There is no work around as I know, at least with regard to preview what will look like the fonts. If you choose not to embed the fonts then the oven should work, but then you won't be able to see what the fonts look like, no?

    What is the team of InDesign epub is simply side load the epub via dropbox or by e-mail. Two of these routes allow you to choose "open with...". "and iBooks will be one of the choices.

    Apple knows about it. I suggest that you remember that, as a customer, you are not satisfied with this behavior and asks that they go back on their decision.
