Change Ctrl.Val.Get or binary write format of LV8.5 until 2014

Hello

I have recently updated from LV8.5 to 2014 and a problem of compatibility. I used the Crl.Val.Get method to get an array of values and save them in a binary file:

to read later with a binary read:

My problem is that the files generated in this way with LV2014 (64-bit) cannot be read by LV8.5 (32 bit) - the result is a "LabVIEW: Unflatten or stream of bytes read operation failed due to corrupted, unexpected or truncated data" error or an application crash.

Writing binary VI changed of LV8.5 ro 2014? Is this a problem for 32/64-bit? Oddly enough LV2014 reads the files generated with LV8.5 without problem. Is it possible for me to this LV2014 program to ensure backward compatibility with LV8.5 (something that I need for a prolonged transition period).

Kind regards

About, unless you set the binary file format exactly (for example define how you store the data in the file until the byte level) I'd be dubious on the file is readable in the new/old versions of LabVIEW - especially if you are using types of complex data as of the beams.

Dealing with backward compatibility would be either define the binary file format and work to that or use a file format string in function (e.g., JSON, XML, INI) for which you can write a compatible rear parser. The OpenG library has screw for saving/loading of the controls in the Panel before a VI in an INI file, for example (even if OpenG stop supporting, it's a format string in function, so you can always write your own parser if you need to in the future). I know that don't helps you you in your current situation, but maybe something to keep in mind for the future.

  • Programatically register values of control only works with Ctrl Val.Get all (not recommended)

    Hello

    I just downloaded "programmatically save 86 vi of https://decibel.ni.com/content/docs/DOC-3551 control values.

    This works.  In the recording, but there an invoke with Ctrl Val.Get All (deprectated) node structure of the event.  I thought that I would get rid of the obsolete reselecting the control method get all.  Of course it was more an (outdated) at the end and the top of the page, little changed from pink to yellow.  However when I run and load a file that is saved I get: error 116 took place to Unflatten chain... Possible reasons:

    LabVIEW: Unflatten or stream of bytes read operation was in pain due to corrupted, unexpected or truncated data.

    A few questions:

    If I were writing this thing without having to download the example it wouldn't work.  Any ideas how I would work in LabVIEW 2011?

    The example is quite old, people would use another method of loading and storage of the parameters in a VI these days?

    This VI crashes after a while.  Is it because he has two event Structures in a loop or because there is no case of timeout or what? (I am not really concerned about why it crashes but if someone knows the answer without wasting time running it I'd appreciate it)

    Thanks for the tips, things that I can draw from this

    The old ways worked with a data type that was {name, type descriptor, flattened data}. The use of new methods {name, variant}, to adapt the code to work with this data type. Also, you cannot use the old data with the new code files.

    I'm assuming that the VI is lock because you have two structures of event in a loop simple (it would make sense, since each structure must wait for an event is to occur), but I'm not the code itself, I can't be sure.

    With respect to the other options, I generally without saving all the controls on a front panel, but when I want to record a bunch of controls, I usually use something like this, which can also work if you collect all the controls of the FP. There are also links to other similar things in the more 'like this' section with the page.

  • How to use ctrl val.get on a Subvi running?

    Hello

    I try to use the Val.Get of control 'Node to invoke' method on a Subvi running to get the values of certain controls to display in a tab. Does she not get the value of the control, it is not updated during the Subvi execution. This particular Subvi displayed a few temperature readings (because now it is just connected to a generator of random numbers for debugging reasons). I have attached my files and I'd appreciate any help I can get. Ultimately the purpose of this exercise is to display a large number of readings of temperature on several tabs with the tab before showing some summary information.

  • CDATA section get lost during the storage of data in binary xml format

    Hello

    If anyone has found any documentation that once you store XML to binary xml format, it will not save CDATA tags? What is the expected behavior or a bug?

    for example, you have an instance xml like this:

    < foo > <! [CDATA [this is CDATA-content]] > < / foo >

    but once save you it in a table that stores this XMLType instance as binary xml, it is what is returned:

    < foo > it is CDATA content < / foo >

    Anyone can shed some light on this?

  • BMP bmp binary &amp; write on MacOSX

    Hello world

    I have two questions for you!

    First of all, I need to convert a bmp to binary file.

    What I'm supposed to do is: open the thread bmp with a file, unflatten dialog, to use it for other animals (convertir convert in grayscale, using a median filter, etc.), and after changing the it, I would like to save it. So I used the flatten pixmap vi and vi of the bmp file writing. But here's my problem: he always write the new txt file, and not bmp! :/

    Second question: I would like to convert the same bmp in binary file. I know how to get from binary to bmp, but not vice versa.

    Any help ?

    Thanks for all!

    Thank you & best regards

    I found the solution.

    I used two different functions to get the binary and hexadecimal representation respectively

    These two functions are:

    
    // function that returns binary data of file
    
    public String getBits(byte b)
        {
            String result = "";
            for(int i = 0; i < 8; i++)
                result += (b & (1 << i)) == 0 ? "0" : "1";
            return result;
        }
    
    // function that returns hex data of a file and writes it to another file
    
        public static String byteArrayToHexString(byte[] b) {
    
            int len = b.length;
            char[] s = new char[len * 2];
    
            for (int i = 0, j = 0; i < len; i++) {
              int c = ((int) b[i]) & 0xff;
    
              s[j++] = (char) HEXBYTES[c >> 4 & 0xf];
              s[j++] = (char) HEXBYTES[c & 0xf];
            }
    
            DataOutputStream os = null;
            FileConnection fcon = null;
            try {
    fcon = (FileConnection)Connector.open("file:///store/home/user/hexfeatures.txt",Connector.READ_WRITE);
    
                fcon.create();
                os = fcon.openDataOutputStream();
                os.writeChars(new String(s));
    
                os.close();
                fcon.close();
    
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
    
            return new String(s);
          }

  • Call data from Ctrl: Vals node

    I am trying to extract the individual elements of the Ctrl Vals invoke node.

    The front of the VI being called is a string and 4 double rooms:

    I am calling the VI and try to read the values as follows:

    The error I get is:

    Could someone please explain what I'm doing wrong here?  I want to just correct the 5 variables from the front of the VI (string and 4 double rooms).  I try to extract it as a cluster only because that context-sensitive help mentions that data Variant is a cluster.  I would ideally unbundle this as well, but I can't even the cluster again.

    The code is also incredibly simple, so I attached the VI.  If someone wants the acutal VI, I can attach it to a future post.  Everything I do called two nodes Invoke to run then get the values of the façade.  And finally try to extract the variables based on Variant type.

    The data type of "val Ctrl. Get all the ' is an array of clusters containing ctrl name (String) and ctrl (option) value.

    You can not (AFAIK) convert these data directly to a cluster of string and double rooms.

    Are the names (labels) and the called VI controls fixed and known data types? If they are, you can select each by name and convert the correct data type.

    I once stumbled on a VI (openG, I believe) who would get the data type of a Variant, but I can't find right now...

    When I create a rectangle, I can not not change the shape of a rectangle with the cursor in illustrator CC 2014 for what?

    Xavigarcia,

    I'm afraid that have met you the Rectangle Live bug that is limited to the MAC versions from 10.7 and 10.8, but not of 10.9 (Mavericks) or 10.10 (Yosemite). If all goes well, the bug will be fixed soon.

    Thus, a switch for the Mavericks or Yosemite with a reinstall might be the way to solve it here and now.

    To get around it, in each case, it is possible to develop direct Rectangles to get the normal old shaped rectangles or Pathfinder > unit, or use the scale tool or the free transform tool.

    A more permanent way round that is to create normal old shaped rectangles, after running the free script created by Pawel, see this thread with download link:
