Add line last 2d array index

OK, I m already curse this bloody language for its illusion of "simple".

I m doing the EASIER operation of any language: filling in a line down to a 2D array. I have just can´t find a way to do it.

I m create a table 1 d with data of type string resulting... then I try to add an array of existing channels and this error pops up when I use the function "Insert into array.

OF COURSE I KNOW THAT THE DIMENSIONS ARE DIFFERENT!, DUH? PRECISELY! A 1 D TABLE SHOULD BE THE LINE OF A 2D ARRAY.

HOW ON EARTH AM I SUPPOSED TO ADD A LINE OF THE SET DOWN TO A 2D ARRAY?

Sorry, this kind of stupidity just pissing me off the coast.

Thanks in advance for any help.

Let me guess - you want to take the 2D HISTORIAL table and add the result to the end of this. This isn't what you are doing. You take a 1 d table and try to write it in a 2D array, that's why it breaks.

The important point to understand here, that's the basic concepts of the data flows, which should be explained in the first LV tutorials - functions operate on the data that you give them, and controls on the front panel are not magical data stores. They hold everything you put into it. If what you want to do, that's what I described, you will have to do it exactly the same way you would in c: A = A + B, where I am the substitution of + can be added. In this case, you need to read the value of the indicator, add to this value, and then rewrite it. You can do this by creating a local variable of indicator (and remember that local variables are not the same as C.) You can use them in the same way, but their main use is to provide points of secondary access to the controls on the front panel. If you use them to store data, you will find probably yourself written race condition critical, because LV tends to be much more parallel to C and they have not the Atomic protections for sequences of reading / writing).

LV is relatively simple. If you suffer with it, I suppose you're one of the people who think much more easily in the field of this text according to use of languages. If this is the case, you might not enjoy yourself. In all cases, it must not to throw everything you know already in terms of LV, because this knowledge do not always translate correctly. You need to take, if you have it, is ordered practical programming, such as keeping your neat code (which isn't your example). I suggest also to take a step back and going through some tutorials, because it is certainly the kind of thing that is explained in them.

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("notesCount") " ""] / 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
        
      
    
  
```

Add lines - which method is the fastest

I work with data in data acquisition and I need to add lines. I came up with two methods of getting that and as I work with pretty big blocks of data I wonder which approach is most effective. Thanks for the help.

Both are methods of 'SLOW' and quite the same.

If you need to go a lot faster, initialize a large array and then use the function 'replace the item.

If you have any problem to speed the first is the simplest method.

Add lines to the query result?

Is it possible to add lines to the result of a shutdown of the SQL query, similar to the CALCULATION command in SQL * more?

In other words, for example, when A column value changes, add a line after the previous line (the last one before changing the column A) to display the sum of the values in column B.

for example

< PRE > A and B
- --
1 3
1 4
1 5
12
2 9
2 1
2-7
1 < / PRE >

SQL> create table sales (person,city,sales)

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.

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.

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

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.

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?

Add the lines of my text file in the PresetEffects.xml

I did once, like this:
```
var scriptEffect = {};
scriptEffect.xml =

    
        
        
    
    
        
        
        
    
;
scriptEffect.matchName = [email protected]();

function installScriptEffect(){

    var ret;
    var file = new File(Folder.appPackage.absoluteURI + "/PresetEffects.xml");
    var str, idx, header, xml;
    var xmlSettings = XML.settings();

    XML.setSettings(XML.defaultSettings());

    try{
        if (!file.exists) throw "ERR_FILE_NOT_FOUND";

        file.open("r");
        str = file.read();
        file.close();

        idx = str.indexOf("");
        if (idx<0) throw "???";

        header = str.substring(0, idx-1);
        xml = new XML(str.substring(idx, str.length));

        if (!xml.contains(scriptEffect.xml)){
            xml.appendChild(scriptEffect.xml);
            if (!file.copy(new File(file.absoluteURI+".bak"))) throw "ERR_CANNOT_WRITE";
            file.open("w");
            if (!file.write(header + xml.toXMLString())) {file.close(); throw "ERR_WRITE_FAILED";};
            file.close();
            alert("Preset installed succesfully. Please restart After Effects");
            }
        else{
            alert("Preset already installed. You need to restart After Effects to make it effective.");
            };
        ret = true;
        }
    catch(e){
        file.close();
        alert(e);
        ret = false;
        };

    XML.setSettings(xmlSettings);

    return ret;
    };
```
Then, when you want to add the effect, check with myLayer.effect.canAddProperty (scriptEffect.matchName).

If true, nothing to do, otherwise use the installScriptEffect function. Normally, it works (haven't tried for a long time).

Hello. I have an existing table, I need to add lines. Is this possible? Thanks in advance.

You could try to reinstall the desktop versions of the third-party programs, but comes perhaps not compatible with 6.2...
