Hi again,
right so I have done what you all said and gone and read a book on LabView fundamentals, "introduction to data aquisition with LABVIEW by RH king"
it has answered my questions about the for loop and most of the rest, the thing I am now having trouble with is the pink lines coming from the DAQ assistant, I have tried all the options, generate signal, aquire, sine wave, digital, continuous samples, N samples but I can't get a pink line, all I can get in that location is a gray "error out", is this all it is, just connect error out to error in.
Also another thing that is confusing me is, just before the graph, that component between the last division and the graph indicator, I am having trouble identifying.
Sorry to keep badgering on about this one but I need to get this example completed for work.

  • Could someone explain how to use of the object Thermometer?

    Hi to all,
    please, could someone write a real example explaining how to use the thermometer in order to indicate the progress of a process like to submit a document?
    I need to do it exactly to indicate this process in Adobe Reader.
    Thanks.
    Dan

    Sorry but I surely have explained my problem badly. I understand how to use the object thermometer perfectly.
    I need to use this object in order to determine the progress of the document's transference when I submit a PDF form from Adobe Reader.
    I'm having problems when I try to do this, and I would like to know if there exists some way to do it.
    b I have tried the following:
    var t = app.thermometer;
    t.duration = 1000;
    // How can I know this value?
    t.begin();
    t.text = "Please wait";
    // Is this a madness?
    while( event.target.submitForm( { cURL: [...], cSubmitAs: [...] } ) )
       t.value++;
    t.end();
    Thank you for your time

    Hi cb-anc!  Thank you for replying to my question.  The Library application has disappeared,not the library folder.  I went into the application a couple of days ago to trash some plist files and now the application has disappeared. I haven't upgraded to Lion but am still on now Leopard.

  • When running labview's test executive I recieve runtime error: Call to step "PRE-RUN" failed. Could someone explain this error?

    I have a set of vi's that work when run under labview. However, when calling these vi's from labview's test executive I recieve runtime error: Call to step "PRE-RUN" failed. in Assign Connector Pane.vi->Call Test.vi->Execute Pre-Run.vi->Test Executive. Could someone explain this error to me? (or ideally tell me how to fix it?) Thanks.

    Hello,
    There are any number of possible causes to this problem. Which version of Test Executive are you using? Have you upgraded your Test Executive recently? The latest version is 5.1.1. If you have changed anything about Test Executive on your computer recently, I recommend you perform a mass compile of all your VI libraries, as having different versions of the VIs on your system could often result in the "Call to Step XYZ Failed" errors. Also, are you using any DAQ or Analysis VIs in your steps? We have seen problems where the use of DAQ or Analysis VIs in the sequence can cause intermittent "Call to Step...Failed" errors. There are some KnowledgeBase entries on our website that discuss this problem. Are you using the Test Executive in the VI environment, or
    as an executable? Again, there are some problems with using Test Executive as an executable that result in these errors, and there are also KnowledgeBase entries that discuss these problems.
    If you have a pared-down application that demonstrates the problem, feel free to send me your VIs and your .seq file and I will try to reproduce the problem.
    Alternatively, I would suggest you visit www.ni.com/teststand to learn about TestStand, our state-of-the-art Test Sequencing software that completely outperforms Test Executive. It is very easy to use and much more powerful, and we have a top-notch support team available dedicated exclusively to supporting TestStand. As you are probably aware, we are no longer developing Test Executive, and instead are concentrating our efforts on making TestStand the penultimate solution for all our customers' test sequencing needs.
    I appreciate your patience on this issue. Please let me know if I can offer further assistance.
    Have a pleasant weeken

  • Could someone explain the Factory Method Design Pattern

    Hi Experts.
    Could someone please explain for me the Factory Method Design Pattern. I read it a little and I understand that it is used in JDBC drivers but i'm not clear on it.
    Could someone explain.
    Thanks in advance
    stephen

    Basically, you have one class that's sole purpose is to create instances of a set of other classes.
    What will usually happen is you have a set of related classes that inherit from some base class. We'll say for example that you have a base class CAR and it has sub-classes FORD, GM, HONDA (sorry Crylser). Instead of having the user call the constructors for FORD, GM, and HONDA, you can give the user a Factory Class that will give him a copy. We'll call our factory class Dealership. Inside dealership, you can have a static function :
    public static Car makeCar(String type)
    if(type.equals("FORD")
    return new FORD();
    else if(type.equals("GM")
    return new GM();
    else if(type.equals("HONDA")
    return new HONDA();
    So when the user needs a car, they will just call
    Dealership.makeCar("FORD").
    This is a good way to hide the implementation of your classes from the user, or if you require complex initialization of your objects.
    Another good example of this is in the Swing library. To get a border around a component, you call static methods on BorderFactory.
    Hope this helped.

  • Could someone explain what is Object?

    Could someone explain what is Object? I have a little
    idea what is it, but not sure. Please give me some
    concret example. Thanks.

    An object is an Instance of a class. A class describes a uniwue entity with behaviors and attributes. For example you can consider your arm.
    public class Arm {
      /** How many hairs on the arm. */
      private int hairCount;  // <== This is an attribute
      /** This is a method to set the hairCount Variable.
       * We dont let the outside user set it directly because that would
       * create problems if we wanted to change its implementation to
       * use a float. In addition we might have logic in this setter to
       * prevent bad data.
      public void setHairCount(final int hairCount) {
        // this is a good example of logic in the set method that we dont
        // want the user to bypass.
        if (hairCount < 0) {
          throw new IllegalArgumentException();
        this.hairCount = hairCount; // <-- Note how we have to use this. to
                                    //     access the instance variable
                                    //     insead of the parameter.
      /** This is a method to move the arm.
       * This is behavior of the class. ONLY behavior pertaining to an arm
       * belongs in the arm class. For example, the method "sneeze" would
       * not belong here but be in the Nose class instead. You can see then
       * that each class describes an entity.
      public void move() {
        // code to move the arm.
    }We have only ONE class per type but we can have many objects. For example the description of an arm does not change no matter who'se arm it is. The data in the class changes but not the actual essence of the arm. So we instantiate two arms for every person (assuming they arent disabled). To instantiate is to create a new object like so.
    Arm myarm = new Arm(): This creates a new object that we can work with.
    So consider the old inteview question of, "What is the difference between a class and an object?" The answer is, "A class is a map or desription of an object; whereas an object is a descrite instance of a class."

    Hi Shirley,
    Long shot, but...
    Open Audio Midi Setup in Applications>Utilities, see the input & output options & KHz setting there, some things will change it for their own use, then not set it back.

  • Could someone explain me about tools like "RICEF"

    Hi Guys,
    Could someone explain me about tools like "RICEF"(I dont know if iam spelling it correctly) and ASAP methodology. Iam wondering how this are related to SAP upgrade and fresh SAP implementation.
    Many thanks in advance.
    Warm Regards,
    Garrick.

    Hi
    It would be helpful to go through the help document of ASAP Methodology.
    The following information may clarify some doubts/requirements you have.
    Generating the Project IMG through ASAP:
    After you have set the project scope, the next step is to generate the Project IMG. From the Business Process Master List (BPML), you can directly access the IMG activities relevant for configuring each process.
    BPML: The Business Process Master List, along with the Business Blueprint, is a key result of the second phase of the Roadmap. Microsoft Excel tables contain the SAP scenarios, process groups, and processes that have been set in scope in the SAP Reference Structure, and are crucial for configuring your SAP System. In Realization, the third phase of the Roadmap, the BPML provides the basis for monitoring and steering test activities and for configuring your SAP System. It contains the titles of the structure items, and displays the status, the owner, links to documentation and links to the SAP System. Amongst other things, the BPML allows you to:
    1) Set your baseline and final scope. These are used for baseline and final configuration.
    2) Access the Project IMG and specific IMG activities assigned to structure items.
    3) Access integration test plans, which help you carry out all required integration tests.
    The Prerequisite is you have set the project scope.
    Process Flow to use the Business Blueprint as a basis for configuring your SAP System:
    1) Set the project scope.
    2) Generate the Project IMG.
    3) Generate the BPML.
    4) From a specific processes in the BPML, you can go to the relevant IMG activities and make Customizing settings.
    Hope this information provides information
    Check the following link for downloading the complete reference document on ASAP.

  • Kernel-fglrx-custom: Please could someone check/improve my PKGBUILD

    I decided to share a script as it has been very useful to me.  I have never written a PKGBUILD before and it took some attempts to make a working one, so please could someone check the PKGBUILD over and let me know how horrible it is and what I should do differently
    https://aur.archlinux.org/packages/kern … ustom-git/
    It installs fine on my PC, but I'm pretty sure that I'm not using the PKGBUILD file properly.
    Last edited by windows_me (2013-08-27 17:18:45)

    There's a couple of things I would change:
    1) The name doesn't really tell the user what the package is for. "kernel-fglrx-legacy" would probably be more helpful.
    2) Rather than pulling a script that will then pull down the kernel package, why not use the existing kernel PKGBUILD in the ABS? You can easily modify that PKGBUILD to apply your script/patches.

  • Please could someone tell me if its possible to get my recording to record roll over captions?

    Hi All
    I am making a recording of some slides in a captivate e learning course to be used as a demo for the course.  Please could someone tell me if its possible to get my recording to record roll over captions.  If I click on the roll over link rather than let the mouse just roll over it, in the recording it records the caption box but before the mouse path gets to it which gives an inaccurate picture of what happens, if I don't click anything then it doesn't record that I rolled my mouse over it.  I'm hoping its a setting somewhere.  I did try and add the captions as an image but then it doesn't show a mousepath aaaagggghhhhh!!!  Any help or hint would be greatly appreciated.

    Hi there, Janet
    I'm confused by your description. Are you saying you have created a Captivate that you are playing back, and recording the Captivate you created using Captivate?

  • Please can someone explain how to delete email addresses?  I have people who when I type in their name it comes up with the correct email address but then when you hit return to confirm it promptly changes the name to someone else (always the same someone

    Please can someone explain how to delete and email address that when typed in brings up one name but when you hit return to confirm it jumps to another name.  I can't find them in my contacts list but they do come up when you type the first few letters of a name.
    EG If I type xyz and the name of the person comes up, when I press return to confirm that's the one I want then it jumps to [email protected],  always the same def address.
    I can't fathom it out.
    Thanks
    Terri

    Try this:
    Start a new email.  In the To address bar, type in xyz like you normally do, press return to confim, and when the address you want to remove shows up in the address bar, move your cursor over the address you want to delete.
    A small triangle next to the name will show up.  click on it, a drop down menu will open, click Remove from Previous Recipients List.  Then do the drop down menu again and Remove Address.
    Good luck.
