• How to build a dynamic array index in the attribute 'to' house arrest

  Hi all
  
  I need to generate xml output with the appearance of multiples of the same complex element. The number of items is calculated dynamically. I use bpelx: append to add items, but I'm crashes when I try to assign values to elements using a variable to index items.
  
  How can you dynamically assign an array index variable in the attribute 'to' a copy instruction? I was able to do in the attribute 'from' the copy statement, following the examples indicated in the documentation for the xpath function. But when I use the concept of intermediate variable, I get a compiler error stating that the query attribute must start with ' / '.
  It works fine when I hard code the index in the attribute of "query" in the statement "copy to".
  
  I use 10.3.3 version JDev and 10.3.3.0 PM BPEL version.
  
  Here are the two methods I've tried:
  ----------------------
  < copy >
  < expression = "concat ('/ client: assTestProcessResponse / client: ScreeningComments / client: CommentItem [', bpws:getVariableData('notesCount'),'] / client: CommentText')" / >
  < variable = "queryText" / >
  < / copy >
  < copy >
  < expression = "bpws:getVariableData('noteText')" / >
  < variable = part of the 'outputVariable"="payload ".
  Query = "bpws:getVariableData('queryText')" / >
  < / copy >
  ----------------------
  < copy >
  < expression = "bpws:getVariableData('noteText')" / >
  < variable = part of the 'outputVariable"="payload ".
  Query = "/ client: assTestProcessResponse / client: ScreeningComments / client: CommentItem ["bpws:getVariableData(&quot;notesCount&quot;) " ""] / client: CommentText "/ >
  < / copy >
  
  ----------------------
  
  Has anyone had a similar problem? Please let me know this is doable and how.
  
  Thank you

  Hello

  I don't know if the following solution is what you want, but I'll try to explain how this would work; (o)

  I understand your question, you have a following like the watch of simple structure xml schema:

  The element is a complex type that has as a child element.
  The element can have 1.. * items

  As you explained that you know how to add loose, common is to use an XML Fragment example

  As you can see now there are two elements with the child element

  After the task to assign the variable content looks like:

  After adding the fragment, you can set the value for the for the first content element in the following way:

  The important thing is to know how to point to the correct position within the payload. It works with that part of the query statement

  [position()=1]
  

  or you can of course use the short version

  [1]
  

  The next task is to dynamically create the reference to the position. Therefore, you can for example use a variable. You can for example something like this:

  And the last step is to set the element of content dynamically using the defined variable

  The only thing to use the defined variable is that part of the query:

  [position()=bpws:getVariableData('Position_Variable')]
  

  Finally, the XML Structure should look like this:

  
    
      
        
          
            Content1
          
          
            Content2

• array index

  Hello

  I built a small VI which displays a table 1 d of the images and a table the values of each image pixel 2D (it becomes 3D). I would like to have access to the array index to view the image with its pixel values (see attachment).

  If there is no way to access the index because it's an exit, I thought about a 2 column table where the first column will be composed of images and the second of all the value of the corresponding pixels 2D paintings. And the display could be done at the same time because it will be part of the same table.

  I don't really know if I can do it. This seems a little strange to build an array of 2D arrays...

  Thanks for your help people. I searched a lot but I've yet to find something similar. I enclose my VI (8.0), the FileInfo.vi becomes just a binary information and I read images all the (320 * 240 * 2) + 1016 bytes (frame size) + size of the header of the frame.

  It seems that Matthew has proposed a solution that looks like it will work (unfortunately, I can't do anything in LabVIEW for the moment because I upset him, and it is essentially suspended... I'm trying to give him a chance to redeem themselves before that I have to abandon the process and lose my other works... ). What I would say to you, is to ignore the idea of how you store the data in the way that you view the data. All you really need to see is a single image and a table 2D pixel values, with a kind of control that allows you to change the image and table 2D display.

  Grrr. Curse you LabVIEW! Who would have thought that you could not put 300 k items in a Listbox and expect it to work... I just killed LabVIEW; at least the automatic recovery tool works.

  So, now that it's the road, I can whip up an example. I have attached a quick example where you can basically copy the block schema and paste it into your vi (just replace table 3 and table of Image controls with the sons of your loop (you can delete the indicators related to these threads).) It is a very simple GUI that allows you to drag the cursor to select an image, and when you do, it will display the appropriate image and a table of pixel values. The node property is here just so that when you run the program, the correct values will appear even before you click on anything.

• How to get the index of element of constant of cluster

  Is it possible to programmatically determine the index (order) of a particular item in a constant of cluster (typedef)?  The cluster is a group of commands, using the control [] array is not an option.

  It seems that this would be an operation of property, but as there are a no "references" for control objects (is there?), there is no properties of control objects.  I use clusters of risk much.  I struggled with the same problem trying to retrieve cluster of clusters of control element names (all roads lead to OpenG :-) don't want to install VIPM :-().

  I use a digital video recorder with a bunch of berries to share data between an application and use in the structures of the element of the Place to read/write tables. Each table (all the bool or slna) represents an array of values to write to the output of the modules (digital and analog).  Usually I only update tables in a loop and read in several screws/loops.

  From the beginning, I stored the data in table form, but later in development, I created typedefs of cluster for clarity when using the data in a FP VI (especially when you read the data in the table and the display on the indicators).

  The exception to the rule of write-once/read many is when I just want to set or clear a single bit BOOL.

  Attached is a picture showing 2 ways to do the same.

  The structure of the DVR read/write on the RIGHT illustrates how I currently updating a single element of an array of BOOL.  In particular, I want to bit - 2 a table named "bOutputCmds".  [bOutputCmds] is an element of a group named "IoCluster" and the "IoCluster" shared across the application by a DVR named 'IoDataRef '.  Safe to update the value of the wick requires 3 operation in Place (in Place DVR R/W in Place unbundle and in square array Index).

  It works very well.  However, the operation requires specifying the index of the little interest, in this case, "2".  I could assign constants for all the special bits, but it would seem more appropriate to enjoy for typedefs that I created. Typedefs allow me to make changes to assignments of IO and describe the configuration in one place.  DVR R/W element on the LEFT illustrates a way to update a single bit (safely) a cluster element name.

  Retrieve the index of the "bLoadEna" item (2) of the typedef of cluster used on the LEFT would make the solution on the much cleaner RIGHT.

  My backup is to replace all the paintings that I originally put in the cluster shared with the individual clusters later I so carefully set or replace all command non - clusters with clusters of the indicator. Or the other works perfectly. For the most part, I'm technically curious because I tend to bang against the limitations of the control clusters quite often.  I seem to be a programmer of NON-INTERFACE in a world of the user interface.

  In fact, my last statement was rhetorical, but it is really quite real.  My request is a controller shipped without a head, so I don't no need or use many controls.  Maybe I should think about some before picking on clusters of risk...

  Fact.

  Thank you

  Peter

• references element-by-element array indexing

  Hello

  I have a simple question. How can I go on a references element-by-element array indexing? For example, when you use a reference to cluster, there is a property node called "controls [of] ' what we spend in a loop for. For a normal array, "enable Indexing" is usually automatically active when you enter a loop for. Why did for an array of references, this is not the case? Thanks for the help.

  Up there, you are working with a reference to a photo table.  Down, you work with a table of references to individual image controls.

  Looks like you do more complicated it must be.

  You can use picture to Pixmap function to get the image data.  And just automatically indexing the images come from the matrix of the images.

• 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.

• How to determine the index of an item in a cluster?

  I have a small program that I put in place, as I'm just trying to get up to speed on Labview.  I have a boolean cluster buttons and for some reason the top button of the page is coming through as Index 3.  There are four buttons in the cluster, but for some reason, there has been a change.  The top must be Index 0.  How to do the things fixed?  I do not see how to determine the index of each button through properties.

  Thank you

  The order of items in a cluster is the same as the order that you added them. To change the order, just right click and select "rearrange controls in the group. If you use Unbundle by name, you don't care the order.

• What is the purpose of the function Array Index in the example attached?

  Hello

  I'm fighting with the Array Index function. I found the attached VI on the OR site which was exactly what I wanted to do, but rather than simply accept that it works and use it, I wanted to understand.

  What is the purpose of the function Index of table inside the while loop? If I put a probe on part and on the other, the values are the same, but if I remove the service and connect directly to the > function, I get an error.

  I do not understand the tables but I don't understand what is happening here. Any help would be appreciated gratefully.

  Thanks in advance.

  

  It is just picking the first reading of the table in the waveform.  If it's good enough (I'd take at least the average of N samples), why not cela?

• How to disable the index to the rows of the table updated

  Hello world

  I have a problem on a table with Oracle11g.

  I would update a table a lines opposite two in a table. This table has an index, and during the inversion, the index is duplicated.

  So, I turn off the index and then rebuild all indexes like this: How to disable the index in oracle

  However, I can't update a table when my index finger is rolled unusable.

  I create my table:

  CREATE  TABLE MY_TABLE(
    ID                         NUMBER(5) NOT NULL,
    TYPE                        NUMBER(1) NOT NULL,
    PRIO                       NUMBER(4) NOT NULL,
    CONSTRAINT PK_MY_TABLE
      PRIMARY KEY (ID, TYPE )
  );
  
  CREATE INDEX  PRIO_UK
      ON MY_TABLE(TYPE, PRIO);
  
  
  
  

  Then I selected all the elements and the results is:

  ID	Type	Prio
  1	1	10
  2	1	11

  Then, I tried to update this list with this script:

  UPDATE MY_TABLE set PRIO = 11 WHERE ID = 1 AND TYPE = 1;
  UPDATE MY_TABLE set PRIO = 10 WHERE ID = 2 AND TYPE = 1;
  
  
  
  

  I have an error on the first line, because the subscript for type 1 and 11 priority already exist.

  You have another solution to solve my problem?

  I thank you very much.

  Do not disable your index. Just perform your update with a single blow. Like this

  SQL> select *
    2    from my_table;
  
          ID       TYPE       PRIO
  ---------- ---------- ----------
           1          1         10
           2          1         11
  
  SQL> update my_table
    2     set prio = case when id = 1 and type = 1 then 11
    3                     when id = 2 and type = 1 then 10
    4                end
    5   where (id = 1 and type = 1)
    6      or (id = 2 and type = 1);
  
  2 rows updated.
  
  SQL> select *
    2    from my_table;
  
          ID       TYPE       PRIO
  ---------- ---------- ----------
           1          1         11
