• Determine which cluster and the array index element was clicked on table clusters

  Hello

  I'm overload of brain with dynamic events and references and nodes of property etc.

  I am trying to identify the cluster and the array index element that was clicked on table clusters

  This gives me the name of the element:

  

  Is this reasonable?  How can I get the index?

  Thank you

  Paul

  Hello

  Download the VI in this link (also attached).  It gives you the index of the array element that you clicked. Hope this will help you.

  Kind regards

• 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

  The error message tells you exactly what is wrong. That is, the line 6 PrintName.java, you tried to access the first element (at index 0) of a table that has no element.

  So, let me ask you which of the study that you did that led you to understand this program, where do you args gets is values of and what do you think, args [0], args [1] and args.length are?

  Copy the following code used to work before I updated to Java 6u26 (my previous version was J2SE 1.5 u6).

  No. I 100% guaranteed you, if you run the same code in the same way, it will give you the same error on any version of Java to 1.1 or earlier.

• 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.

• 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?

  

• 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.

• Reference element of the array by name

  Hi, I have a table containing the different sprites... I am wanting to make reference to the sprite I want by its name rather than by its index in the table, and I was wondering if theres an easy way to do this? I know I could do a loop through all elements in the array and to see that we have a name that is equal to the name I'm looking for, but is something in the sense of myArray [elementName] possible?

  Well, if you did a loop for, you could then do something like:

  myArray .name = i;

• Offset and length are out of the bounds of the array or count is greater number of elements from index to the end of the source collection.

  Simply press on this one and I look forward to any other idea.

  Here's the code-

  $Cluster = "clustername".

  $esxpass = "password"

  "$esxcheck = foreach ($vmhost get-cluster-name $Cluster | get-vmhost | select name)"

  {VIServer is Connect-Server $vmhost.name - root - password $esxpass user}

  "foreach ($vmhost get-cluster-name $Cluster | get-vmhost | select name)"

  {$vmhost.name viserver-disconnect-confirm: $false}

  Works fine on a 16 node cluster, but fails with the error on a cluster to 31 knots

  Are you sure of this code?

  What exactly are you trying to do?

• read the elements and index of a table

  Hello

  I use the function buildArray to build a table 1 d of 1024 items.

  Aferwards I want to extract all items + index of all the elements in another goal.

  I mean if e.g. the 1st element of my table is 10, the second is 45, the third is 65 and I want to have (0.10), (1: 45), (2, 65).

  Can you please help me.

  Use a loop FOR.  AutoIndex your table.  Use the table to build inside the loop TO create a table of the index (starting from the terminal i) and your indexed element.  Connect the new array to the output of the loop FOR (again, use autoindexing) to create a 2D array.

• Convert a table to a cluster of 4 elements array values 2D 2D double precision, or a table 1 d

  Y at - it an easy way to convert a 2D cluster table (4 elements each including a Boolean value and three numbers dbl) to a table 2D or 1 d of double precision values? I need to store my data in a text file to control a robot, I'm trying.

  Thank you.

  There are 1 million different ways to do it. The best thing to do would be to leave the data exactly as it is and simply use Flatten in XML format (search the palette). It accepts virtually any type of data, including a 2D cluster table as you described. He will spit human readable (although not necessarily nice) text that you can write to a text file. Then, read you data from the file and use Unflatten of XML to do the reverse.

  Or you can use a similar model to flatten your data in a 1 d of double table which you can then unflatten.

  

• using the formula node array index

  Hello

  I'm new to labview...

  I am creating a vi that takes a number n and out the primes from 0 to n (i.e. including 1).

  My approach to do, he uses a formula node, but I can't understand how the table index or for each number first output.

  It seems that my indexing algorithm works very well, but I'm just pushing it into the array as an element.

  It'll will be great if someone could take a look at my vi and give me a hint on how to index properly.

  Thank you

  your output should be a table and index first use [index]

  also you have to declare the index and Prime]

  Indeed, I need a few accurancy in switching of signals (Timewhise).

  Is it possible with an NI USB-6216 to use somehow the clock shipped equipment to trigger the next table sent to the digital output index?

  I found evidence for it, but by the data sheet, this device also has static DIOs. If I understand your message, static DIOs are the kilelr for my app, right?

  What is the killer for your application is the source of command DIO.  Timed software DIO won't work with high precision, if you need for the material to something that supports triggering of the OID material - in USB format which means a USB 625 x for a M-series or a x 634 for the X series (beware the series 6341 x only supports timing on 1 port material - check the specs for yourself before decide you)
