How to use the elements in the array

Hi, I am trying to automate a questionnaire using table.

In the compositionReady for the scene

SYM. Actual = 0;

sym.arr = ['Hi', 'Love', 'You'] / / this is my picture of the issue.

sym.checkArr = function() { / / this function I use to check the issue table whis I'll use.}

sym. Question = arr [real];      I want to use the value 'Hi' and then increase my 'real' var and then use the value 'Love '.

}

In my symbol calendar, I use a trigger in the trigger that I use

SYM. Stop();

sym.quest = sym.getComposition () .getStage (). Question; / / I get the value of the Question;

Sym. $("Ask") .html (quest);                                                        "Ask" is an empty textfield;

sym.getComposition () .getStage (invested) ++;                    Increase 'real' for the nex time.

But the code does not work, I think that the problem is the way I use the array index.

Help, please!

Thank you =)

at the outbreak of timeline you why did you use a local variable?

It is advisable to use local variables when possible. The quest variable apply only to this trigger, and it will not be postponed to another trigger in the same timeline. So when you use a trigger to set the HTML for a text element in the same timeline, I find cleaner to assign a new value of a local variable HTML.

and if you call the 'real' global variable of Manager compositionReady of why didn' there you call him with all the way like ' sym.getComposition () .getStage (invested) ++; '?

I think I have didn't express it as clearly as I could have. When you declare sym.actual in compositionReady, you actually declared a variable whose scope is the symbol of the main stage - it is not a global variable. To declare a global variable (which is not always recommended), your code in compositionReady would be:

real = 0;

This real variable would now be accessible from any element/symbol in the composition simply by assigning a value to the membership. You can see how quickly this could be embarrassing.

So back to the scope of variables: If you declare a symbol variable using sym.varName, any element in the same scope may call using sym.varName. If your main scenario triggers can call without using the full address of sym.getComposition () .getStage () invested ++. Instead, you can simply use ++ sym.actual. Less code and easier to read. But if you call from another symbol (outside), you need to use the full, addressing the address actually the variable, i.e., sym.getComposition () .getStage () invested ++.

HTH,

    Yep, use Index Array as Gerd says. Also, using the context help ( + h) and looking through the array palette will help you get an understanding of what each VI does.

  • How to use the node function call library for a function in the dll with the data SUB type

    Hi all

    I would ask for your kind help

    I am facing a problem with the call library node.

    I have a C++ (stdcall) function, which has Sub as data type

    XXXX error code (hwnd, lid, getValue, * Sub data1, * Sub data2)

    data1 and data2 types are constantly changing based on the value of 'getValue '.

    Mainly I can use the call library node several times and adapt each node according to the types of data data1, data2 and extract the values and use in the code. Here is no question. Real question is:

    My question:

    How can I use a node of library time call and make a case according to the 'getvalue', who will control the data1, data2 data type. Here I really seeking solutions.

    My tests:

    I used varaints as entry to the libray call node of the data1, data2 and selected parameters in the call libraby node as "Adapt to type. Here labview just crashed.

    I appreciate your suggestions to feedbackand.

    Thank you

    Karine

    You must allocate enough space for data1 and data2, and then pass a pointer to this space. An easy way to do this is the function to initialize table. Set the U8 type and size for the number of bytes required. Pass this array to the function as a pointer of table data.

    After the function call returns, you need to extract the data in the table. You can do it manually, but a simple approach is to use the array of bytes to a string. Then, in a housing structure, use Unflatten chain to convert the string to the correct data type. This method also converts the "endianness" which will be probably necessary; Be sure to only set all entries for unflatten correctly.

    It defines a page will be loaded in the background when your application starts.  This page is intended to run any startup logic (for example starting listeners - Push is an excellent example) that your application may need to depend on, without any user interface.

    This background page is WITHOUT user interface.  Any attempt to interact with the user interface (for example change the DOM, calling alert() statements, etc.) will result in no action.  Nor will calls to redirect, since the background page does not interact with the pages of foregroud - if no query string.

  • How to use the ESD document with structured templates

    Hello

    I started to learn working with SEDD. I have an existing ESD, now I'm suppose to use it to create documents. I created a new book and imported this ESD file to it. I can see all the items in the catalog of the element. But when I start to add items to the book and add a new document, the elements are turning to red. Referring to the User Guide, it is said EDD cannot be used directly and must be used with structured patterns. But I do not have these models structured with me. Can someone please tell me how to create these structured templates and how to use the ESD file with these models, and out of this problem.

    Thanks in advance.

    Although ESD exist in the form of a separate document, the only way that it can be used is when it is part of the model. As a model of structured FrameMaker, a structured model contains master pages, pages reference, character formats, paragraph formats, etc. IN ADDITION, a structured model contains a DSP. To add the EDD to your template file, or any document FrameMaker who will use it, open the template file and the file of ESD. Click anywhere in the template file, and then select file > import > element definitions. In the dialog box, select the EDD file as source and click Import. Then save the template file.

    To use the template file, open it and save it as a FrameMaker document, giving it the name you want. You can now create your structure.

    If you use a book, all documents in the book must use the same ESD. Open the template file. In the book file, select all the documents in the book. Then select file > import > element definitions. In the dialog box, select the template file and click Import. Once completed, all documents in the book have the same ESD. In addition, ESD is copied into the file of the book itself.

    You say:

    But when I start to add items to the book and add a new document, the elements are turning to red.

    It is is not clear to me what you do. While it is true that SOME elements of a book are in the book file, you cannot add a book of items in the folder (at least not as far as I know). In general, the book file, it encapsulates elements around the documents root elements in the book. You may need to update the book to get a part of the Red disappear lines. You may need to rearrange items in the structure of the book to remove the red lines.

    Hope this helps,

  • Can I call a function using the array index?

    I defined a table that stores the name of the function, like this:

    var aresetButtonTop:Array = new Array(resetTop1,resetTop2,resetTop3,resetTop4,resetTop5);

    Then I have a button named "btnresetTop" which, once clicked will be called one of the five functions stored in the array (aresetButtonTop) above. Functions are called at runtime depending on certain conditions. I need to figure out how I can call these functions using the array index. I use the following code to call the function. The value of i has already been calculated.


    btnresetTop.addEventListener (MouseEvent.CLICK, aresetButtonTop [i]);

    After doing this, I get the following error when I click on the button:

    TypeError: Error #2007: parameter listener must be non-null.
    at flash.events::EventDispatcher/addEventListener()
    at gallerytest_fla::MainTimeline/thumbTopClick()

    Note: thumbTopClick() is a function within which all these codes are written.

    I need to know if it is posible in AS3 to call a function name using array index or not. If so, could you afford ehelp me out.

    You can certainly do.

    In your case, it looks like i is out of range. Show your loop.

  • With no headphone jack, how to use the iPhone in my car 7

    Okay, so here's the challenge.  I have a power source and a headphone and not Bluetooth.  It works perfectly with iPhones before 7.  But with 7, it isn't possible to use the same configuration I had for years.  I own my car, and I have no interest in buying a new car just to support a new phone.  And since this will be a problem for the years to come if I stay with Apple, I would like to know what are the solutions are available.

    So, how to use the new iPhone 7 while remaining responsible and using my car speakers?  Dongles Bluetooth that I need to reload, it's probably not.

    Thus, looking for ideas that might have people.  I can't be the only one with this concern.

    It's almost a certainty that a third party adapter will appear quickly. The new Macbook has a single port usb - c and people asked the same question, 'how to load and use USB at the same time." There are today dozens of solutions for the Macbook, and then it will be with the iPhone 7. An adapter with a 3.5 mm jack and a port of loading Lightening would be my guess. Kickstarter entrepreneurs are probably already working on it.

  • How to use the capture and the print button

    I tried to figure out how to use the capture and the "print" button, or add or what you call. I press it and the whole page of a different color changes, so I try to cut the section I want but I don't know how to send it to the printer. Can someone help me with this. I'm not at savvy with tech stuff, but when I find a recipe or something and it doesn't have an option to print a certain area, I can't understand how to use it?

    Thank you

    Andi Starbuck

    That happens to me is, I click and drag to make a rectangle of yellow selection, and as soon as I raise my finger on the mouse button, the part I've selected is captured as an image, a new tab opens and preview before printing, the image display. I can use the installation of the Page or simply print. But if I close the preview, this temporary image vanishes and I'm back on the page where I started. You see something different?
