Updating data in User Event doesn't propogate to uses of the User Event type

So I have a user event which is seeded with a cluster in which there are a few typedefs. Now, as you might expect, I have to pass the user event to different VIs so that they can trigger the events which are interpretted by a main vi. Pretty simple and all is happy. There's one rub though: one of my vis which is passed the user event is called by reference. The call by reference vi requires a certain vi pattern when you create the reference for the vi (namely, a strictly typed vi reference), which includes the user event type. Now, sometimes, I update the typedefs in the data type of the user event. This means that user event type changes. Now, what's maybe not too surprising, is that either the user event type doesn't update with the type def or that the type specifier vi constant doesn't update with the change in user event type. This means that every time I have to go back and create a type specifier based on the updated pattern for the vi which takes the user event as an input.
Is there a way for labview to automatically do this? One way to fix it, I'm sure, is to change the user event input into the vi I call by reference to a variant. Then inside the vi I call, to type cast the variant with the output of a Create User Event vi that has been seeded with the appropriate cluster of typdefs. But that seems pretty silly (like, why not just make EVERYTHING a variant). Any ideas?
- Chris

Take a static VI reference (from the app control palette), drag your subVI into it, right click it and make it strict and wire it into the type input for the Open VI Reference primitive. Now it should always update.
Two more advantages you get from this is that now the VI is in memory, so it will automatically be included in your build and that you can use the VI Name (or VI Path) property from the static reference to get the name for the Open VI Reference primitive and it will always work correctly.
Try to take over the world!

  • When i want to install update to my iPhoto,it will tell me i am not the user of the account,becoz i had brought from another person,how?

    Dear sir,
    when i wanted to update my iPhoto app. It tell me i m not the user account,because i had brought from somebody?how to get it do my update again?
    thank you.

    Please test after each of the following steps that you haven't already tried. Stop when the problem is resolved. Back up all data before making any changes. Keep in mind that no one here represents Apple or can help with customer-service issues.
    Step 1
    A purchased app can only be updated by signing in to the App Store with the same Apple ID that was originally used to buy it. There's no way around that limitation, which also applies to free apps. If you can't sign in with the buyer's ID, delete the app and reinstall it. You'll have to pay for it again, if applicable.
    Step 2
    If you get the alert when trying to update a bundled iLife app, select the Purchases page in the App Store and locate the app in your purchase history. If there's a button marked ACCEPT on the right, click it.
    If you have a used Mac, the bundled apps were linked to the original owner's Apple ID and can't be transferred to you. Reportedly, customer service has issued redemption codes to some second owners who asked, but it's not guaranteed.
    Step 3
    If you're trying to update iLife or iWork apps that were installed from a purchased DVD, or if you have a refurbished Mac bought directly from Apple, contact App Store customer service for a redemption code. You may be asked for the part number of the DVD.
    Step 4
    From the App Store menu bar, select
              Store ▹ View My Account
    Enter your Apple ID password at the prompt. At the lower right corner of the window that opens, click the Reset button. Close the window.

  • After updating to 6.0 iPhone doesn't show in iTunes for the wireless sync

    I have the iPhone 4s, after updating to 6.0 it doesn't show in iTunes for the wireless sync. My iPad which is first gen. still shows up. If I plugin with usb it shows up but as soon as I unplug it disappears.
    When I click on the sync wireless on the iPhone , it trys to sync but nothing.

    it's okay, it is not silly. but yes it was on but i went ahead and turned it, (the phone) off rebooted and turned it back on and rebooted phone again to see if it helps it any.... but to no it did not change, it still doesn't show up. as well as when i look in on wifi and see choose network mine is not populated until after a couple seconds. so it has something to do with not being able to hold on to a wifi signal when going to sleep or putting phone to sleep via power button. i do not see the wifi signal meter until a couple seconds after i wake it up from sleep. and now neither my ipad or iphone show up in itunes. so there is issues i guess with something. i have tried everything an dam too frustrated to do anything more.

  • A glitch in my use of the change event

    I have a script in the change event of a drop down list field that works when a certain choice is made then another field becomes visible. I am trying to get that field to become visible when when a record from a database populates the field the correct value. Right now all that happens is the drop down field shows the correct value but the field in question isn't visible.
    Here is the code I am using for the change event.
    var contractLangs = xfa.event.newText;
    if (contractLangs == "Creative Works Unlimited")
    xfa.form.form1.MainPageSF.ContractSF.ContractLanguageSF.presence = "visible";
    else
    xfa.form.form1.MainPageSF.ContractSF.ContractLanguageSF.presence = "hidden";
    I can't figure out how to get the field to become visible when right value goes into the drop down field.

    I don't think I have been explaining this very well so here is another try.
    I have a Drop-down List called "ContractTypeList" that has three items in the list;
    Limited Permission
    Creative Works Unlimited
    Commission for Creative Works
    If Creative Works Unlimited is chosen a hidden Drop-down List called "ContractLanguageList" becomes visible otherwise if either of the other two are chosen then it is hidden.
    I would like the "ContractLanguageList" to be hidden or shown depending on which item shows in the Drop-down List when I cycle through records in a database. Right now it only works with user interaction.
    I'm not sure what to do. I have been using the line, xfa.even.newText. If anyone can help me out it would most appreciated.

  • Error in Windows 7: User Profile Service was not logged on. The user and administra​torprofile

    Error in Windows 7: User Profile Service was not logged on. The user profile can not be loaded. Administrator profile and the code does not work. What do I do?
    HP G5384sc desktop pc

    Hello
    Unfortunately I did not manage to fix my computer yet. My printer is broken so I bought a new one, but since I do not have administrator rights, I can not connect the new printer, so I have to write all-installing notes down with pencil and simultaneously translate them into Danish so it is a very slow process. I'll tell you if it succeeds, otherwise there is of course the primitive way to buy a new computer, but it's the same as giving up. Not yet.
    Until now, many thanks for the good suggestions.
    Kind regards

  • Event.rc and Restriction of inputs from the User...

    Im using Adobe Professional Live cycle designer 7.0 to design pdf form. Also, Im using an existing pdf (supplied by the customer), which is designed through teleform designer (with adobe 6.0) model for this design. In the existing one, the javascript methods are working fine for restricting keys, validation, etc. But these scripts are not working in designer as the designer is using XFA model.
    Im trying to restrict the key inputs (like only numbers/characters should be entered). But I couldnt find the equivalent statements for some of the statements (which are used in the teleform pdf).
    For eg.
    event.rc = true. Allows keystroke to be added to entry. event.rc = false. Prevents keystroke being added to entry in the following function:
    function TFTemplate_KeyStroke( mask )
    if (event.willCommit) {
    return;
    var value = AFMergeChange( event );
    if (!mask.test( value )) {
    event.rc = false;
    app.beep( 0 );
    But I couldnt find the matching statements in Designer for event.willCommit, AFMergeChange(),event.rc, etc.
    If I get, I can restrict the inputs.
    Expecting any solutions from you...
    Thanks in Advance...

    Hi,
    Based on your description, I understand that you want to use application or some functional tools and then
    monitor the user printer job. When be greater than a certain number, it will need to acquire additional information. As I know, it seems that there is no such function can meet your requirement. Sorry for it.
    In addition, I find that you use a third-party software for this functionality before. Please check and confirm
    if you can get a new version (or some updates, service package) that may help it to be supported in Windows Server 2012.
    Hope this helps.

  • IOS4 Update on 3GS New Restore- "iPhone (Name) is in use by another user"

    The initial problem I encountered on my 3GS to iOS4 update was I couldn't do ANYTHING that required the network, e.g. Facebook, Safari, certain apps, youtube and more. I was told by an Apple in-store rep to restore AS NEW IPHONE instead of using my backup info, so I did.
    It works almost perfectly now. However, I just attempted to make a new playlist and sync it to my iPhone and I am getting the message "iphone (Name of my iPhone) is in use by another user on this computer"
    The problem with this is that I am the ONLY user on this computer and have been since I have had it.
    My photos will sync through iPhoto but iTunes is no longer recognizing my iPhone's name or the device. I am not sure what caused this, but any help would be awesome.
    Since the new update I changed the name of my iphone but I do not see why that would be an issue.

    1. You are thread-jacking. Kangdequan has an open question and adding unrelated questions to that, will not help him at all. Kangdequan, please see below.
    2. There have been countless articles in the last few years explaining why some countries have iTunes music stores and others not. The main reason is something called copyright.
    3. There is an Apple app store in the Philippines.
    4. There are many other sources of music.
    Kandequan. It may be that something has become corrupted, but I also see a problem in that the iPhone is only supposed to sync with one computer. Trying to sync with a second one will not work.
    There are a number of things you may need to do now, but first decide which computer is to be the one that you sync with: the master, if you will.
    Whichever one you decide on, you need to make sure that all files point to that and there is a process written up by a user "wjosten".
    You may also need to follow the Apple suggestions for making iTunes recognise your device.

  • Where does firefox cache the form parameters to be used in the reload event of a page that was the resposne of a HTTP POST request?

    Suppose there is form in a web page and it submits data in HTTP POST method. After submitting the form, if I reload the page [either by the refresh button or back button; whichever applicable], firefox asks permission to resend the form data by saying "To display this page, Firefox must send information that will repeat any action...". Now if the user clicks on the resend, firefox resubmits the form data.
    So where does firefox store this from data for such future resending/resubmission?
    Is it possible to retrieve/manipulate those stored form data?

    I thought I'd tried that, as tried lots of other things like encoding URL, but obviously not as this works.

  • J2ee_admin is used as the user when RFCs are run on the web dynpro appln.

    I have created a web dynpro application which has some RFCs on the model.
    View is an adobe form which send the data to the RFC and upon submit executes the RFC to create an item in SAP (xRPM).
    When the RFC is run, user is taken as J2EE_ADMIN even when authentication is enabled on the application and
    a different user is used.
    Is it due to the adobe form or  the web dynpro application?
    Is there anyway we can change this default and capture the user logged in accordingly.

  • How can I allow a user to control my Edge Animation using only the scrollbar?

    I have seen a few examples of an Edge Animation being conrolled by the scrollbar, and I am wondering how I could achieve the same effect.
    Example:
    http://dominikruckli.ch/scrolltest/scrolltest.html
    I have searched the corners of the internet and have found 2 or 3 different tutorials, but none of them have proven successful.
    In basic terms, I am creating an animation that involves a character getting from Point A to Point B, from the beginning of my timeline to the end.
    Rather than exporting my animation so that it plays automatically, by itself, I would like for a user to scroll vertically, and the playing of the animation moves in conjunction with the scroll bar.
    As the user scrolls from top to bottom on the scrollbar, the character in my animation moves from Point A to Point B.
    Also, if the user stops scrolling... the character will stop moving as well.
    In addition, I would like the surrounding area, outside of my stage, to remain hidden. I do not want to allow the user the ability to scroll around and see off of my designated stage area. I only want the scroll bar to act as a playhead for the animation.
    Any help will be greatly appreciated.
    Thank you
