Teststand XML Translator For LOOP Step

HI, I'm trying to write an XML translator usinc the C++ example. So far I made work "if" , "while" , "end" and i'm trying to make the "for" loop working as well but i have a issue when i insert the dataProperty.
The XML code i wrote id the following :
<Data dataProperty="InitializationExpr" type = "string"> <Value>"Locals = 0"</Value> </Data><Data dataProperty="ConditionExpr" type = "string"> <Value>"Locals < 10"</Value> </Data><Data dataProperty="IncrementExpr" type = "string"> <Value>"Locals += 1"</Value> </Data>
so the issie is that is i use the " " it works in the PropertyBrowser window but not in the For Loop window and if i dont use the " " is the opposite.
I even tried to change the property CustomLoop followinf the same syntax but it doesnt work:
<Data dataProperty="CustomLoop" type = "bool"> <Value>true</Value> </Data>
can anybosy help me with this?
thank you
Luca

If I use Locals.X == 10 it gives me an error in the Number of Loop field in the For Loop window. What i really would like to know is how to set the properties for every step because beside few of them that i can set with dataProperty="ConditionExpr" or dataProperty="TitleExpr" i dont know how to set the other ones.
For istance if i want to have a Sequence Call (I already wrote code so to have more then one Sequence) in a Sequence that calls another one i can have code like this:
<Sequence name="MainSequence">
<Step name="CallSeq2" type="SeqCall">
</Step>
</Sequence>
<Sequence name="MainSequence2">
</Sequence>
now I dont know how to pass values to the step so to fill the File Pathname and Sequence fields in the Module window can I use dataProperty? and in cas I can what is the Sintax?
thank you
Luca

Office-2007-xml-Translator for Staroffice

I found the following on the web.
Has anyone tried it out with StarOffice? Is there something similar for SO8??
The OpenXML Translator provides support for opening and saving Microsoft* OpenXML-formatted word processing documents (.docx), spreadsheet documents (.xslx) and slideshow documents (.pptx) in OpenOffice.org.
The odfconverter-1.1-7.oxt file works only with Windows, and the odf-converter-1.1-7.i586.rpm file works only on SUSE� Linux Enterprise, SUSE Linux, and openSUSE. On both platforms, the OpenXML Translator works only with the latest Novell� edition of OpenOffice.org.

I haven't had any Debian or StarOffice users test OCI yet, but either/both should work. Please try the Ubuntu instructions for the strawberry edition.
If you have problems, follow the testing instructions and also let me know:
- The location of your OOo executable like /usr/bin/soffice (there may be several)
- Which version of libtiff you have
Sorry about the poll: I added StarOffice. Duh! :)

How do i configure a FOR loop to have the behavior of the step Loop Type: Pass/Fail count?

Hello,
I'm using the Pass/Fail count set to one Pass to capture an event generated by my DUT. I originally used a numerical compare step with the Looping type of Pass/Fail count to accomplish this. Unfortunately the implementation changed and now I need to execute a few steps that can not be combined within one code module as before. Nor can these steps be put into a subroutine. One of the steps executes a .NET asembly and I haven't figured out how to pass the reference to the subroutine. When the subroutine is intered the reference is lost and the methode does not execute correctly.
I have an evaluation function the exits the loop when the expected conditions are met. Everything works except for the Overall Pass/Fail result of the For loop. If the loop exits due to the first numerical compare test passing, I want the loop overall execution to report as "Passed". If the loop reaches it's predetermined number of iterations, the overall result needs to report as "Failed". It would also be nice to have the radio button functionality of "Record Result of Each iteration". Some conditions require a wait over a minute for the event to occur and I don't want to generate needless data for the report.
Currently I get the pass/fail status for each For loop iteration, but only "Done" for each loop iteration. I don't want the initial few failures to cause the test to fail.
Does anyone know how to do this? Suggestions?
Thanks,

I have 2 steps in the loop that can not be combined into one step. This forces me to implement the behavior in some form of loop. A While Loop could be an option. I would need to pass the Step.Result.Status from the Multiple Numerical compaire step to the condition of the While Loop. I tried to use the Step.TS.ID without success. Some form of reference to the numerical compare step would be needed. I'm using a For Loop as I do want to limit the number of iterations of the loop. In the case where the loop iterations are reached, the event I am trying to detect did not occur at the correct time and a failure needs to be reported.
I came up with something based on my comments in the second post:
1) To start with I configured a Locals.ForLoop_5 variable. This is used to set the limit on the loop iterations and for comparison after the loop has finished executing. More on that later.
2) The first step inside the loop invokes a method within a .NET assembly that has been packed in a DLL This method gets the required data from the DUT and stores it to a text file.
3) The next step is the Multiple Numeric Limit step. This step invokes a VI that extracts the data from the text file. This step has been customized in several ways.
i) In Run Options, the Results Recording Option was disabled. This prevents recording of "Failed" while the loop executes when waiting for the event to happen.
ii) In Run Options, the Step Failure Causes Sequence Failure is unchecked. Same reasoning as i) These steps are not true failures.
iii) A Post Action is configured to go to the nexxt step after the For Loop End step On Condition True with the logic of Step.Result.Status == "Passed". This causes the loop to exit when the first "Passed" is encountered which corrolates with the event I'm trying to detect. On Conditon Fail remains set to default.
4) The step after the For Loop End is an expression step with everythin set to default except for the Status Expression logic set to: Locals.Loopindex < Locals.ForLoop_5 ? (Step.Result.Status = "Passed") : (Step.Result.Status = "Failed"). This step performs the overall Pass/Fail reporting for the For Loop. If the number of loop iterations is less than the maximum it could have only gotten there by the previous logic triggered by the numerical compare passing, therefore "Passed". If the loop index has reached the limit, then the event was not detected, therefore Failed.
I have tested this work around with success, it just a pain to now have to implement this on my 40 some odd For Loops.
If there is a better way, I'd still like to hear it.

For loop and xml - how to point the right content in a XML file with a dynamically created button?

Hi Everybody,
as my first experience in AS3 I'm bulding a photo multigallery. In that gallery I have some buttons, each one pointing to its respective set of images.
Each button is created with the for loop, that picks the information from a XML file. From this XML I get the text of the button, the position etc. What I did with some sucess. But there is a scary problem: I don't know how to make each button load the respective and unique set of images.
I've tryied several different methods, with no effect, to make each loop to give to each button an unique identity to load the respective set of images.
I imagine that the solution pass by the use of arrays. I wrote some code, and I guess that I'm almost there (but not sure). Here is my AS3 code until now:
// CREATE MENU CONTAINER //
var menuContainer:MovieClip = new MovieClip();
menuContainer.x=10;
menuContainer.y=300;
addChild(menuContainer);
// CREATE IMAGES CONTAINER //
var imagesContainer:MovieClip = new MovieClip();
imagesContainer.x=10;
imagesContainer.y=10;
addChild(imagesContainer);
//// LOAD XML ////
var xmlLoader:URLLoader = new URLLoader();
xmlLoader.addEventListener(Event.COMPLETE, whenLoaded);
xmlLoader.load(new URLRequest("XML/roiaXML.xml"));
var xml:XML;
function whenLoaded(evt:Event):void {
     xml=new XML(evt.target.data);
     var mySetsList:XMLList=xml.children();
     //// MENU BUTTONS ////
     // CREATE ARRAYS //
     var totalArray:Array = new Array();
     var setNodesArray:Array = new Array();
     var setNamesArray:Array = new Array();
     // POSITIONING BUTTONS INSIDE MENU CONTAINER//
     var rowsQuantity:Number=3;
     var columnsQuantity:Number=Math.ceil(mySetsList.length()/rowsQuantity);
     var cellWidth:Number=160;
     // CREATE BUTTONS //
     for (var i:int=0; i< mySetsList.length(); i++) {
          var newSetButtonMC:setButtonMC=new setButtonMC();
          //what do I do here to make it works? To give each button created a unique id.
          setNodesArray.push(i);
          //trace(setNodesArray);
          var imageNodesArray:Array = new Array();
          for (var j:int=0; j<mySetsList[i].IMAGE.length(); j++) {
               imageNodesArray.push(mySetsList[i].IMAGE[j].attribute("imageTitle"));
          totalArray.push(imageNodesArray);
          newSetButtonMC.setButtonText.text=mySetsList.attribute("galeriaTitle")[i];
          newSetButtonMC.setButtonText.autoSize=TextFieldAutoSize.LEFT;
          var cellX:Number=Math.floor(i/rowsQuantity);
          var cellY:Number=i%rowsQuantity;
          newSetButtonMC.x=cellX*cellWidth;
          newSetButtonMC.y=cellY*(newSetButtonMC.height+10);
          newSetButtonMC.addEventListener(MouseEvent.CLICK, onClick);
          menuContainer.addChild(newSetButtonMC);
     totalArray.push(setNodesArray);
     //// MENU BUTTONS ACTIONS ////
     function onClick(mevt:MouseEvent):void {
          trace(totalArray [0][0]);
          trace(totalArray [0][0]);
          // in the line above I achieved some success loading a specific info from XML.
          // but I don't know what to do with it.
          //what do I do here? To make each button to load its own node from XML.

Thanks everyone . ABSTRATO

you can assign each newSetButtonMC and ivar property that points to its i value or, even easier:
// CREATE MENU CONTAINER //
var menuContainer:MovieClip = new MovieClip();
menuContainer.x=10;
menuContainer.y=300;
addChild(menuContainer);
// CREATE IMAGES CONTAINER //
var imagesContainer:MovieClip = new MovieClip();
imagesContainer.x=10;
imagesContainer.y=10;
addChild(imagesContainer);

     xml=new XML(evt.target.data);
     var mySetsList:XMLList=xml.children();

          setNodesArray.push(i);

          for (var j:int=0; j<mySetsList[i].IMAGE.length(); j++) {
               imageNodesArray.push(mySetsList[i].IMAGE[j].attribute("imageTitle"));
         nextSetButtonMC.imageArray = imageNodesArray;
          //totalArray.push(imageNodesArray);
          newSetButtonMC.setButtonText.text=mySetsList.attribute("galeriaTitle")[i];

Step in for loop

Hi all,
Is it possible in a for loop to iterate with steps ? For example :
for i in 1..500 loop , but I want the index i to grow five by five ! Is it possible ? Is there a keyword to use to accomplish this ? My database is Oracle10g !
Thank you !

Directly you can't control the iterator of FOR LOOP (no change possible, no INCREMENT clause).
You can use another index to control iterations::
SQL> declare
2   j integer := 1;
3 begin
4   for i in 1..5 loop
5     j := i*5;
6     dbms_output.put_line('i=' || i || ', j=' ||j);
7   end loop;
8 end;
9 /
i=1, j=5
i=2, j=10
i=3, j=15
i=4, j=20
i=5, j=25

Unable to establish a for loop in custom rtf template for seeded xml file

Hi Experts ,
I am Unable to establish a for loop in custom rtf template for seeded xml file. i am using <?:for-each:G_BSALINE?> FORM FIELD .....<?:FOR-EACH?END> .AM i missing something?
Please help.
Thanks

Hi,
Need more information about your XML data structure; however based on the code you provided, the synax does not look right; you have some colon sign where it is not needed etc... You could use the following (although not quite sure if you want to use Form Filed to group by or just display), but look at the example provided below.
<?for-each-group:G_BSALINE?> FORM FIELD .....<?end for-each-group?>
Example code:
<?for-each-group:G_INVOICE_NUM;./INV_TYPE?>
xxxxxxxxxx
<?end for-each-group?>
Thanks!

Best practices for logging results from Looped steps

Hi all
I would like to start a discussion to document best practices for logging results (to reports and databases) from Looped Steps
As an application example - let's say you are developing a test for one of NI's analog input or output cards and need to measure a voltage across multiple inputs or outputs.
One way to do that would be to create a sequence that switches the appropriate signals and performs a "Voltage Measurement" test in a loop.
What are your techniques for keeping track of the individual measurements so that they can be traced to the individual signal paths that are being measured?
I have used a variety of techniques such as
i )creating a custom step type that generates unique identifiers for each iteration of the loop. This required some customization to the results processing . Also the sequence developer had to include code to ensure that a unique identifier was generated for each iteration
ii) Adding an input parameter to the test function/vi, passing loop iteration to it and adding this to Additional results parameters to log.

I have attached a simple example (LV 2012 and TS 2012) that includes steps inside a loop structure as well as a looped test.
If you enable both database and report generation, you will see the following:
1) The numeric limit test in the for loop always generates the same name in the report and database which makes it difficult to determine the result of a particular iteration
2) The Max voltage test report includes the paramater as an additional result but the database does not include any differentiating information
3) The Looped Limit test generates both uniques reports and database entries - you can easily see what the result for each iteration is.
As mentioned, I am seeking to start a discussion for how others handle results for steps inside loops. The only way I have been able to accomplish a result similar to that of the Looped step (unique results and database entry for each iteration of the loop) is to modify the process model results processing.

Repeating nodes using FOR loop but when concating XML string then concating only last iteration of FOr loop ??

I stuck with a problem that I am using FOR loop for generating repeating nodes.
Now when I concat the generated node in the main node then I got only last iteration of that FOR loop.
can anybody suggest me a way to handle this error....
FOR i IN 1..pl_phone_tab.Count
LOOP
SELECT xmlelement("Phone"
                                    ,xmlelement("PHONETYPE",xmlattributes('01' AS "dmnADRP_PHONETYPE"),pl_phone_tab(i).p_phtype_tab)

here I am getting only one node but there has to be two nodes for PHONE node

Not that I'm encouraging you but here are two standalone examples explaining how to do what you want :
1) Loop through the input collection and append each node to its target container :

Can I reduce the execution time for a step in a TestStand ?

Hi,
I calculated the a single step execution time for TestStand Ver 2.0. It comes to around 20 milliseconds/step. Can I reduce this excution time ?
Are there any settings available for configuring execution time parameters except result logging and exception handlings to reduce the execution time ?

It's difficult to tell how you what time you are reporting for your step. Clearly we don't have control of the time it takes your code to execute. However, we are constantly working on reducing the overhead of calling the code. In addition, you don't mention the type of step you are calling. One way to have a common reference is to use the example \Examples\Benchmarks\Benchmarks.seq. Below have have posted the results of running this sequence with both tracing and result collection enabled and then disabled. I have a 700 MHz, 128 MB RAM, Dell PIII laptop. In this example there is no code within the code modules. You notice that calling a DLL has the least overhead with a minimum of 7.459 ms with tracing and results enabled and 0.092 ms with tracing and results disabled. Although not included below, if I enable results be disable tracing I get a minimum time of 0.201 ms, a 100x improvement on your time.

Weird problem with loading data from an XML using a for loop

Hi,
I have a strange problem. I have encountered this thing many a times but still don't know the proper workaround for it.
I am trying to load swf file, a video file or an image. They can be present on a local system or on a remote server also. All the entries corresponding to the files to be loaded is made in an XML file. I traverse through the nodes of the XML using a for loop. On the complete event of loader info, example:.
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onComplete);
I fill a container with the loaded data.
My problem is when I am using for loop it doesn't works properly but if i use a statement like this:
someFunc()
     if(i<arr.length())
     ... do something...
     loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onComplete);
private function onComplete(e:Event):void
... do something...
i++;
All files are loaded properly.
I think this can be because the for loop processes pretty fast but the content takes time to load, which ultimately leads to some wierd results.
Please let me know how can this thing be done correctly by using a for loop also.

You don't want to use a for loop to load several items. The way you almost appear to have it is the proper approach... load a file and use the completion of its loading to trigger loading the next file.

Executing each step of a for loop only on a VISA read output

Hi,
I would like to give multiple steps to a motor/controller to exectue, but I keep getting a "command overflow" error. Therefore, I am trying to tell the for loop only to execute when the VISA Read receives an output. I have included the .vi I have written so far. For example, the code /1P1000p66R tells the controller to move motor "1" forward 1000 steps and then to output the number "66" when the motor has moved 1000 steps. My input to the "table control" is, e.g., 3 commands:
/1P1000p66R
/1D1000p66R
/1D5000p66R
How do I get the code to send each of those commands only when the number "66" is sent back to the program so that I don't get the command overflow error? Also, if anyone has a better way to control the motor to do multiple steps, let me know. I'm pretty new to all of this.
Thanks.

Rather than using a table control, I would just use a string array.
Set your serial port parameters before the loop. Close the serial port after the loop.
Your controls don't have any real data in them saved as default, so I'm confused a bit as to what your are trying to do. Why do you have a numeric control with the number 0 establishing the loop iterations?
Instead of a For Loop, use a while loop. Set the 1-D array of strings to be autoindexing at the input tunnel. Write the command (why you have everything wrapped in a case statement with a true constant makes no sense. Do a VISA read. If the response has the 66 (you'll have to figure out how to parse it out), all is good. If it does not have the 66, or the number of loop iterations equals the number of commands in the array -1 , then end the loop.

OnLoadInit within xml for loop

Hi,
I have some code that loads in xml which works fine (see
below)
I have a for loop, and based on the content of the XML, swf's
are loaded in to moving clips.
when each of the swf's have completed loading in I need to
change the clips scale, position etc.
I need to indroduce to the code below some way of detecting
when each swf is loaded. I have been doing research and know I need
to integrate a loadInit function into the code. I have tried
alsorts and looked at alot of code but can't seem to get anything
working.
If any of you can poinbt me in the right direction that would
be great.
stop();
var y:XML = new XML();
y.ignoreWhite = true;
var page_cat_ids:Array = new Array();
var page_cat_names:Array = new Array();
y.onLoad = function() {
var category:Array = this.firstChild.childNodes;
for (i=0; i<category.length; i++) {
page_cat_ids.push(category
.attributes.cat_id);
page_cat_names.push(category.attributes.cat_name);
duplicateMovieClip(_root.characterClipContainer.characterClip,
"characterClip"+i,
_root.characterClipContainer.getNextHighestDepth());
_root.characterClipContainer["characterClip"+i]._x = 100*i;
_root.characterClipContainer["characterClip"+i].characterClipName.text
= page_cat_names
_root.characterClipContainer["characterClip"+i].characterClipImage.loadMovie("../images/f lash/characters/"+page_cat_names+".swf");
y.load("../xml/categories_page_1.xml");

Sorry, I missed something out.
there is however another problem. As the code loops it is
adding the page_cat_names to each other. Because of this the movie
is loading in the first swf but can't find the others becuase they
dont exist.
see the error from my output panel below. the trace is coming
out at the end though.

FOR loop in XML Publisher

Hi,
Is there a construct to run a loop for a specific number of time?
Like 'FOR i in 1 .. 5 ' ?
Thanks,
Ashish

Instead of that FOR loop,
you can use the recusrsion,
by putting a sub-template , and call it by passing the number as parameter ,
following is the sample XSL code.
<xsl:template match="test">
<xsl:call-template name="loop">
<xsl:with-param name="var">3</xsl:with-param>
</xsl:call-template>
</xsl:template>
<xsl:template name="loop">
<xsl:choose>
<xsl:when test="$var > 0">
test
<xsl:call-template name="loop">
<xsl:with-param name="var">
<xsl:number value="number($var)-1" />
</xsl:with-param>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
weird
</xsl:otherwise>
</xsl:choose>
</xsl:template>

Problem with continue in a for loop

Hi all
I have a variable of type Node[] which contains nodes like Text,ImageView and SVGPath etc...
now i want to filter that group which means i want to separate the Text nodes for that i used a for loop as
var abc:Node[];
var abcsize=sizeof abc;
var textarray:Text[]=for(i in abc){
if(i.toString()=="Text"){
   i as Text; //casting Node to Text
                 }//if
           else{
                  continue;     //if the node is not of type Text then i am skipping that one
                 }//else
      }//forwhen i am trying to compile this i am getting the compilation error as

- This is a real bug in the compiler, obviously. I wonder if I haven't meet it already, or something similar. Maybe you should report it.
- The problem is that your code is incorrect anyway: the branch with continue doesn't return a value, so cannot be used in the list building. Well, at least that's what I suppose which confuses the compiler. You can try and return null (which will be discarded) instead of using continue.
- But your code can be much more efficient, compact and perhaps even more readable, using the powerful JavaFX sequence comprehension:
var seqMixed = [ 1, "one", Text { content: "Ichi" }, Circle {}, 2, "two", Text { content: "Ni" } ];
println(seqMixed);
var seqFiltered = seqMixed[ obj | obj instanceof Text ];
println(seqFiltered);
seqFiltered = seqMixed[ obj | not (obj instanceof Text) ];
println(seqFiltered);
