Event structure in "for loop" and stacked sequence

I tried to put an event structure into a for loop sequence, then used a pause button to pause the program (one loop with event structure.vi). The pause button functioned normally since the program could be paused whenever the button was pressed. Then, I put this for loop sequence into a stacked sequence (Problem.vi), which has 2 frames and every frame has the for loop sequence in it. After the pause button was pressed once, the pause button and stop button will no longer effective anymore. Where should I modify so that this program will work properly? Thanks a lot.

Ah, at last something weird !
The answer is simple : don't do that !
You should either avoid having 2 event structures handling the same events, or learn how to process dynamic events.
Why didn't you read the answers to a question posted a few hours ago (still on the overview page of this forum ?). See here.

Event Structure in Timed Loop in real time cannot work

I am a new user for LabVIEW. And I met a problem which really frastre me!!! Hope someone can help me out. Thanks in advance!
I simply want to use event structure under timed loop, which is extrmely important in my design.
However, this works very good in my computer (without connect to FPGA).
Once I connect it to FPGA, then I can run it still but there is no response!
My file is attached. Please somebody helps me!
Looking forward to your answers!
Solved!

The FPGA runs headless. Event structures are not going to work. What you need to do is have an application on your host where the user presses a button, changes a value, etc. That event should send a message via TCP/IP to the code running in the real time environment. Then the real time environment should set a control on the FPGA to the value you want.
In general, real time programming with FPGA has multiple layers.
1) Host code-> handles user interactions and communicates them to real time code via TCP,UDP, etc. Displays data to user sent from the RT controller.
2) Real time code->runs headlessly. Handles messages from Host code, processes FPGA data, communicates with FPGA much like the host code communicates with the real time code
3) FPGA -> does acquistion and passes it via FIFO to the RT
The first thing you need to do is understand the architecture and how all these pieces of the puzzle work together before throwing things down on a diagram.

Outlook to iPhone sync failure – Sync suddenly stopped working for calendar events but continued for contacts and notes.   Finally Fixed!!! SUPPORT TEAM – PLEASE SEE THIS – Complete explanation of cause and correction steps.

The issue: Outlook to iPhone sync failure – Sync suddenly stopped working for calendar events but continued for contacts and notes.   Finally Fixed!!!
SUPPORT TEAM – PLEASE SEE THIS – Complete explanation of cause and correction steps.
The cause: It is now clear what caused this problem. For years I had several “all-day” events in my Outlook calendar (birthdays, anniversaries, etc.). In May 2012 I decided to make some of them one hour events so I could add alerts to remind me of the event. I did this by dragging them in Outlook to the time I wanted and expanding them to the time slot desired and then adding the alarm.
The symptom: Syncing stopped working for the calendar but continued working for contacts and notes. I didn’t realize sync was failing until months later when I missed two very important phone calls, so when I noticed it the cause was not obvious.
The failed attempts: I’m head of a software firm and my calendar sync is a crucial to my business life so I took this on with a vengeance. From a quick look at events in Outlook and the iPhone I could see that the problem started in May 2012. Events before May were in both Outlook and the iPhone but events after May were only one or the other. Unfortunately I had changed several other things at the same time relating to other events so again the cause was not obvious. MANY calls with AppleCare proved them incompetent so my internal IT guys assisted trying many things. We tried a huge number of calendar changes and several versions of iTunes, iPhone OS and Office as well as both iPhone 4 and 5, all without success.
The fix: After 18 months of frustration, MANY hundreds of $ expense and MANY hours of wasted time I saw a blog that had a calendar sync problem and it indicated all day events were related. I changed the display of the Outlook calendar to the list view, added columns so I could see “all day” event check marks as well as times of events, sorted on the “all day” event column to move them to the top, and for all events that were “all day” events AND had a start and end time, I removed recurrence and then added the annual recurrence back…
After I fixed all events that had BOTH “all day” set and had a start/end time, I tried another sync. It synced for the first time in 18 months!
Problem occurred May 2012 – fixed Nov 2013

Hi, to remove dummy '_ModGrp' entries, rather than crashing the 'Suppr' key on your keyboard, you can use this basic VBA macro (launched for instance from Excel).
It will recursively remove all '_ModGrp...' folders
Sub RemoveFolders_Click()
    Dim oOutlook As Outlook.Application
    Set oOutlook = New Outlook.Application
    Set objNameSpace = oOutlook.GetNamespace("MAPI")
    Call CleanFolders(objNameSpace.Folders)
End Sub
Sub CleanFolders(objFolders As Outlook.Folders)
    For i = objFolders.Count To 1 Step -1
        If Left(objFolders(i).Name, 7) = "_ModGrp" Then
            objFolders.Remove( i )
        Else
            If Not objFolders(i).Folders Is Nothing Then
                Call CleanFolders(objFolders(i).Folders)
            End If
        End If
    Next i
End Sub

How to code a parallel 'for loop' and 'while loop' where the while loop cannot terminate until the for loop has finished?? (queues also present)

I've attached a sample VI that I just cannot figure out how to get working the way that I want. I've labeled the some sections with black-on-yellow text boxes for clarity during the description that follows in the next few sentences. Here's what I want:
1) overall -- i'm intend for this to be a subVI that will do data acquisition and write the data to a file. I want it to use a producer/consumer approach. The producer construct is the 'parallel for loop' that runs an exact number of times depending on user input (which will come from the mainVI that is not included). For now I've wired a 1-D array w/ 2 elements as a test case. During the producer loop, the data is acquired and put into a queue to be delt with in the consumer loop (for now, i just add a random number to the queue).
2) the consumer construct is the 'parallel while loop'. It will dequeue elements and write them to a file. I want this to keep running continuously and parallel until two conditions are met.
      i. the for loop has finished execution
      ii. the queue is empty.
   when the conditions are met, the while loop will exit, close the queue, and the subVI will finish. (and return stuff to mainVI that i can deal with on my own)
Here's the problems.
1) in the "parallel for loop" I have a flat sequence structure.. I haven't had time to incorporate some data dependency into these two sequential sections, but basically, I just care that the "inner while loop" condition is met before the data is collected and queued. I think I can do this on my own, but if you have suggestions, I'm interested.
2) I can easily get the outer for and while loops to run sequentially, but I want them to run in parallel. My reasoning for this is that that I anticipate the two tasks taking very different amounts of time. .. basically, I want the while loop to just keep polling the queue to get everything out of it (or I suppose I could somehow use notifiers - suggestions welcome)... the thing is, this loop will probably run faster than the for loop, so just checking to see that the queue is empty will not work... I need to meet the additional condition that nothing else will be placed in the queue - and this condition is met when the for loop is complete. basically, I just can't figure out how to do this.
3) for now, I've placed a simple stop button in the 'parallel while loop', but I must be missing something fundamental here, because the stop button is totally unresponsive. i.e. - when I press it, it stays depressed, and nothing happens.
suggestions are totally welcome!
thanks,
-Z

I'd actually like to add a little more, since I thought about it a bit and I'm still not quite certain I understand the sequence of events...

So i read a bit more about the 'dequeue element' function, and as I understand it, since there is no timeout wired to the dequeue element function, it will wait forever, thus the race condition I suggested above can never happen!
Yes, you got it!
As I've thought about it a bit more, there's a few things that surprise me... first, the reason the 'dequeue element while loop' errors is not because there's nothing in the queue, it's becaues the queue has been released and it's trying to access that released queue... However the problem I have is this --- Even though there's no timeout wired to the dequeue element, I still would think that the while loop that contains it would continue to run at whatever pace it wanted -- and as i said before.. most of the time, it would find that there is nothing to dequeue, but once in a while, something is there. however, it seems that this loop only runs when something has been enqueued. the reason I say this is illustrated in the next code sample MODv2 that's attached below. I've added a stop button to the "queue size while loop" so the program runs until that is pressed. I've also added a simple conditional in the "dequeue while loop" that generates a random number if it a button is pressed... but this button is totally non-responsive... which means to me that the "dequeue while loop" isn't actually continuously running, but only when an element is added to the queue. this still seems almost like the 'dequeue while loop" waits for a notifier from the queue telling it to run. can you explain this to me? because it is different from what I expect to be happening.

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.
Here is my XML:

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);
//// 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"));
         nextSetButtonMC.imageArray = imageNodesArray;
          //totalArray.push(imageNodesArray);
          newSetButtonMC.setButtonText.text=mySetsList.attribute("galeriaTitle")[i];
          newSetButtonMC.setButtonText.autoSize=TextFieldAutoSize.LEFT;
          var cellX:Number=Math.floor(i/rowsQuantity);

I'm having problems manipulating array data within a for loop, and extracting the required sub-arrays generated.

Hi,
I'm using labVIEW V5.1
I'm trying to generate 10 1D arrays, the first array is initialized to all zeroes, then I have set up a for loop which shifts the first element by 1, then a random number is placed into the first element position. I am using a shift register to feed back in the newly generated array into the start of the loop.
By the end of the each loop I want to be able to use the array generated in an algorithm outside the loop. However I only want the Nx1 array that has just been generated.
Unfortunately, I cannot figure out how to resize, reshape or index the output array to do this.
I would like the loop to
give me out a 1D array after each iteration.
Any help would be greatly appreciated.

I hope I've understood your problem.
First your vi was lacking of the sub-vi working as shift register, I've replaced it with the rotate function.
The indexing of your arrays create a 2D array whose rows are your 1D array.To pick only one of them you have to use the index array function and select which one you want.
To use your temporary data in another part of your application you should use a local variable of array2.
I did it in a separated while loop That I syncronized with the for loop using occurrence, in this way the while loop runs each time a new value is inserted in array2 (each loop of the for loop structure).
If you don't need this syncronization just get rid of occurrence functions.
I place a delay in the for loop to show what happens when running.
Hope it was helpful.

For Loop and Void Method Questions

Question 1: How would I write a for loop that repeats the according to the number entered, to prompt the user to enter a number (double) between 1 and 100. If the number is outside this range it is not accepted.
Question: 2 Also how would I write a for loop to do sum and find the average of the array numbers in a seperate void method( does not return anything to the main method)?
Question: 3 (first code snippet) With my for loop that is used to process each number in the array and square it and cube it and display the results to 2 decimal places. How do I make it so say I want the array to allow me to enter 2 numbers (so I enter 2 numbers) then it asks me to enter a number between 1 -100 (which will prompt 2 times) that it shows me the results for the entered numbers between 1-100 after one another instead of number then result number then result like I how it now.

If I understand you correctly, use 2 loops. One gathers user inputs and stores them in an array/List. The second loop iterates over the array/List and does calculations.

Node removing in a Tree, for loop, and Enumeration

Hi there
it should be pretty easy, however i'm stuck with this code:
public void supprNode(DefaultMutableTreeNode node){
for(en = node.preorderEnumeration();e.hasMoreElements();){
DefaultMutableTreeNode tmpNode= (DefaultMutableTreeNode) en.nexElement();
if (tmpNode instanceof myderivedNodeClass)
tmpNode.doSomething();
if(!tmpNode.isRoot())
removeNodeFromParent(tmpNode);
}The problem is, the for loop doesn't traverse all the elements. That's if i call removeNodeFromParent. Is the enumeration updated twice?
ie if my tree is
root
-1
-2
-3after the call of supprNode(root) i get:
root
-2And i really don't understand why.

Hi!
If you look at the apidoc of DefaultMutableTreeNode.preorderEnumeration() you will see following text:
* Modifying the tree by inserting, removing, or moving a node invalidates
* any enumerations created before the modification.
So you should copy the elements of the enumeration in a separate list and iterate then over this list!
With kind regard,
Mathias

Best fit lines for loops and sine waves

I am trying to find a best fit line that will work for sine waves and loops (hysteresis loops). I can get the sine wave just fine, but when I switch to a hysteresis it just puts a line across the middle (I assume because of the 2 y values for every x). I am doing data acquisition that will take in both forms and graph them. I tried a polynomial fit and it doesn't work at least the way I implemented it and I tried a few others but it looks like they are all function based. Also, my y values are coming out of a Bessel filter. I don't think this would be affecting anything but I thought I would put it in here incase it does.
Did I miss one that I haven't tried that works for my application?
Thanks
Patrick

What problems did you have with extract single tone. Can you show some data where the results from it are not good?

I need to take elements from within 2 nested for loops and place them in an array at the specific row and column that I need.

I have tried intializing an array and replacing elements by specifying a particular row, and column, but in the end I get an array with only one element replaced, and I suspect that it is because as the for loops are running through their iterations each time the array is re-initializing. I have a simple vi that I will post below, it is not the exact situation that I have but is a good place for me to get some understanding. I have the row and column indexes being driven by the inner and outer loop iterations, which gives me the pattern I need. I am using the inner iterations as array elements. How do I set this up so that it works and d
oes keep re-initializing my array.

I have fixed a number of things in your vi.
You were right in thinking that the array was continuously re-initialized. To avoid this, use a shift register (right-click the loop border), which will pass the updated array into the next iteration.

Please help with the FOR loop and the array..

I was trying to place some words in the Movie Clip
"TextPanel" and set a
random position to each of them.
But it's not working.
1) I created a Movie Clip "word" and inside that MC I created
a text field
and gave it an identifier "textFiled".
2) The linkage name for Movie Clip "word" I set to "word".
3) In the actionscript I created an Array called "aWords".
4) Then I created a FOR loop that should
place (attach) Movie Clips "word0", "word1", "word2" and
"word3" to the
movie clip TextPanel, and set the textField text for each of
them to the
text from the Array.
But the script attaches 4 Movie Clips with a name
"Undefined", instead of 4
different names (from the Array).
What is wrong with this script?
var aWords:Array = [apple,banana,orange,mango];
for(i=0;i<aWords.length;i++){
var v = TextPanel.attachMovie("word","word"+i,i);
v.textFiled.text = aWords
v._x = randomNumber(0,Stage.width);
v._y = randomNumber(0,Stage.height);
Thanks in advance

But in my Post I already wrote v.textFiled.text = aWords
so I don't understand what were you correcting..
And one more:
I have tested it by changing the
v.textFiled.text = aWords; to v.textFiled.text = "some
word";
and it's working fine.
So there is something wrong with the Array element, and I
don't know why..

Help with a FOR loop and an object array

I need to make a for loop that takes an array of objects that contain the parameters year, type, and model (all ints) and sort by year, then divide the array in all the objects with the same year and sort them by type, then divide the array again into the objects with the same year AND type and sort them by model.
the object a Dress objects, the get methods are get+nameof parameter.
the array is a 1D array called Dresses.
I have made a paralell array to store the value of the parameters and sort that then move the array acording to that sorted array. The problem is in the division of the array.

We'll give your request to do (or finish) your homework for you the attention it deserves.

Handle Error in for Loop and finish the iteration

I am using a for Loop now i encounter an error.

Any Parallel to "Continue" in JAVA or any other solution for this...
