• Display static and dynamic photo using the Structure of the event

  Hello everyone,

  I need to display a static image with an event and then using another event, I need to keep displaying the second photo, while the first is still displayed. Simply speaking, in the attached example, I would like to have the color circle black fixed while I dynamically change the red circle.

  My attempt is shown in the attached VI with the first approach using the shift register and the second using the property node (value). Both do not work. Does not erase the previous red circle, or the black circle also gets deleted.

  I'd appreciate any help in this regard.

  Thank you

  From what I see here, you must have two shift registers, one for each circle you try to draw.  You just update those who need update inside the corresponding event.  Use then Cancatinate string to combine the two images.

  Other things to note:

  Put the terminals of your controls in their case of discipline.  This ensures that you are using the most recent data instead of the outdated data.

  The Stop button event take the changed value.  Yet once, put the terminal inside the event.  This will allow the latch to work its magic.

  Them would like to see photo subVIs RADIUS be I16 instead of DBL.  I recommend that you change your cursors to use representation I16.

  

• using the structure of the event in the LabVIEW classes

  Hello

  I'm new in the use of LabVIEW classes, so don't know much how I can use them.

  In my main program, I have clusters with five elements in each. The elements are controls two States and in some groups, there are three States controls. The user will press the buttons (controls), and different things will happen. In my first program were I not using classes, I had a structure of the event and the controls were cases of event in the structure.

  Is it possible to somehow use an event of cases in one of the methods that is created in the classes, so that say, that's not in the main program?

  I have attached two photos: I wanted to have a structure of the event in servoTouchEvent (in left.tri.lvclass) who is a child.

  Let me know if my explanation is not clear.

  Grateful for the help!

  Hello

  Yes, you can have a structure of the event in a Subvi rather in your main VI of top-level UI. The trick is to use the 'Save for events' and passing in references to orders that you want to have the event trigger structure for. The refnum output since the function is entered in the terminal of dynamic event of the structure of the event who could live in a Subvi. You can add instances of event where you will see these control events as dynamic events then you can do something with. These excerpts from shows all the code in a simple diagram, but the stuff in the structure of disable diagram could easily transformed into a Subvi:

   

  All this can be done without classes. What will buy classes you include the ability to encapsulate your screws and also perform different code based on what object on the hierarchy of the parent-child classes is on a wire. If the behavior of your code is different between 2-3 State and controls (which I do not know what state controls 3 you are referring), you can take advantage of the classes.

• Trigger several events to a dynamically saved value of signage

  I have different controls for some pumps.

  I want to stop all with an emergency stop button.

  I use the event Structures to manage the user controls.

  In the previous version of my code, I register all events statically in the same vi. But to make the program compact and modular, in the attached version of the code, I use the references to the controls, and I go to a Subvi. In the Subvi I record the events of these references and I link the "event recording refnum" to the terminal dynamic events of the Structure of events.

  Everything works with the exception of the emergency stop.

  I can't use a reference of the emergency stop button to trigger the event, because the emergency stop opens the other files in vi for further confirmation from the user.

  When the emergency stop is confirmed by the user, I use the value property of a signalling to trigger the event stop of all structures event of the subgroup on the screws that control the pumps.

  Previously, I had only a single value of signage to trigger several events, but I saw that I have create the condition of critical competition and the Structure of events first, which handles the event, removes it from the queue, and other Structures of the event can't get the event.

  So, I use as signals of many boolean value pumps as much as I.

  But it does not always raise all events.

  Another detail, it is that I do not use the "Unregister for events function" in all the screws under that have Structures of the event. I saw no difference with this function, or without him...

  Apparently, Miss a clue of a general principle of LabVIEW.

  I join all of the template project.

  The main.vi starts the program.

• Improvement of timeliness

  HI again,

  I enclose a developed VI which takes in data from an external source (engine in this case) and stores the data. However, its delivery rate is very slow.

  I guess it happens so because I write data on the hard drive in the "block average VI. I tried using shift registers, but they do not seem to work in this case.

  Please see the attached VI and suggest how to improve his speed because it will be used for the acquisition of data high-speed.

  Thank you!

  Dheeraj,

  Is seeing several things that can contribute to your slow execution.

  1. in the DT.vi channels you create channels, set up the calendar, start the task, read the data and stop the task.  Configuration does not change from one iteration to another so why repeat it? Implemented for continuous play and move everyuhing except the DAQmx Read out of the loop.

  2. as you work with tables, why not read the data as a table 2D rather than an array of waveforms, which then converted to dynamic data, then back to berries?  A single Index Array function would replace the Signal Split and all the convert dynamic Date primitives.  In addition with the array of Index it is clearly evident what is happening. Dynamic functions and data structures tend to hide things behind configuration dialog boxes.

  3. the Express calculators are probably quite slow compared to the screw assessment polynomial which act directly on the numeric data types.

  4. the average Dt.vi of the block calculated exactly the same average as the average instant DT.vi, and then a little more.  Why the calculation twice?  Just make the average instant as an additional output of the DT.vi block average production and eliminate average instantaneous (or use it as a block average suVI.

  5. you have several Quotient and the rest of the functions and comparison functions that duplicate the calculations.  Simply use the result of one of them in multiple places.

  6. If the values of the controls cannot change in the course of a race, move them out of the loop.  The loop didn't need to read every time.  The values are treated as constants inside the loop.  Obviously Stop must be inside the loop because it changes during a run.

  7 son run behind other objects and son achieve the difficult to read diagram.

  See the image below for a purified to the top of DT version.  At the top of the loop is a construction showing what I was talking about points 2 and 3.

• What shared variable caused the event?

  Hello

  I save the shared variables to trigger the event (see attached photo). How is it possible to detect which shared variable triggered the event, but not analysis of chain of the shared Variable in the terminal dynamic event of the structure of the event?

  Thank you.

  Hello Martin,

  Looks like you have access to the shared variable that raises the event, take a look at the photo in the following link:

• Skillfully manage large number of controls

  My user needs dictates I have controls 14 to 28 on a total of 7 tabs (2 to 4 controls by tab). Half are simple doubles, the other half are Boolean values. I'm trying to think of a more elegant way to manage changes in value for these controls to have separate user from 14 to 28 events. I thought of the event handling on each tab grouping, for example, 'Double1, value or 2 change' and then using the reference property and the label of the control to determine who's been changed, but it seems clutzy. I was wondering if someone had a better idea or is the best way to go despite having 28 of them separate user events.

  I build an array of references to the command and then use the dynamic event of the structure of the event. See attached example.

• Strategies for bridge (structs) containers to the c dll table ++

  Does anyone have any suggestions for the passage of tables of containers (C structs) between TS and c ++ dll? I have exhausted my understanding here. I noticed that when I create a type which is an array of containers (size = 1), allow to move like a C struct but exclude the container as C struct, and then type presents itself as a struct rather than an array ref in the C++ dll parameters dialog box. I was hoping that I could exploit something here, but not luck.

  As a last resort, I could try to flatten the structures in an array of double, pass it as a VARIANT and rebuild on the other side - yuck!  I have hundreds of different transfers to manage that way, so I'm still holding hope for something better.

  In C/C++, I think that if you define a structure with a table like this:

  struct {Topic2

  int sizeVar;

  Topic1 array [size];

  }

  Then, the size is fixed. It doesn't really change because the compiler whenever you allocate a variable of the type of structure, must allocate enough space to store all the items that you have declared in the definition of struct. In other sizeof (Topic2) includes the full size of the array defined using the constant of 'size' that must be a constant, not a variable. If you want something more dynamic, you declare your structure as follows:

  struct {Topic2

  int size;

  Topic1 * array;

  }

  you dynamically allocate the memory for the array pointer and release it dynamically when you're finished with it.

  A simpler approach, that you can take, if the size range is quite small, is to make the Board as large as size max you will ever need and add another Member to say how many items in the table is actually being used. And it seems that your def struct is close to that, but not quite right. For example, I'm sure that you can not use the size for the variable field and the size of the array. Instead, you probably need something more like this

  struct {Topic2

  int numElements.

  Topic1 table [taille_max];

  }

  Hope this helps,

• Problem stopping construction of the central loop of three-loop vi.

  I have a "invite user input" in the central loop of three vi in loop.

  I wish that the loop stops when the user presses '2' on the front panel and then check "entry" at the prompt.

  I'm doing it with an event 'user '. Can someone tell me what I am doing wrong?

  Thank you.

  Add a dynamic stop the case structure the event stop in the upper loop editing event stop and add events, user event_value dynamic change... and you can leave out the stop in the 2nd event, wire a test case structure command constant to stop tampering.

• PDF bookmarks are not correctly indented

  I have one small unstructured FrameMaker document 2015. When I generate a PDF file, the bookmarks are not indented correctly.

  The document includes sections in the following order:

  Level 1

  Level 5

  Level 5

  Level 4

  Level 5

  Level 5

  My bookmark PDF settings are:

  Level 1

  . Level 2

  .. Level 4

  ... Level 5

  When I generate a PDF, I get the following:

  Level 1

  Level 2

  Level 5

  Level 5

  Level 4

  Level 5

  Level 5

  It is relatively bet back, dealing with level 4 as another level 5 and then further indenting of level 5s that are level 4.

  Someone at - he already seen this before? Any suggestions for fixing (apart from changing the order of the items)?

  It is a design problem. You will need to manually adjust the PDF using Acrobat bookmarks or come with different paratags and levels not to break implicit structure. Have a critical look at the semantic meaning of the paratags you use where there may be alternatives to level 5 to the location that you have placed the. Also what happened to level 3 and how that will work in bookmarks when it gets used somewhere in your documentation?

• XMLDataSet filter

  This should be simple, but I can't find the answer at the moment. I am trying to apply a filter to a spry table to select a XMLDataSet by selecting a value from a Spry validation.

  < div spry: region = 'ds3' >
  < select name = "sΘlectionner" onchange = "ds3.setCurrentRow (this.value)" spry: repeatchildren 'ds3' = > "
  < option value = "{ds_RowID}}" > {Type} < / option >

• Dynamically add cases to the other structure

  Hi guys

  I have a simple ordering application. This ordering application now has only 4 basic commands and their corresponding enterprise value. But as we test the Council we want to send some arbitrators order and if this command works basically 'save us' this command and test more. But as the labview application is done in one place and run in different place that I can't update the program. Can I dynamically?

  Thank you & best regards

  Loïck

  In theory, you could detect the new command, save it in a table, and then see that you get it again (using search 1 table D).  But how you process this order where you will have problems.  In short, a new case cannot be added to a structure business while the VI is running or after it has been compiled into an exe file.

• Dynamically retrieve "rank" in the hierarchy to determine the next member to be inserted into the structure?

  Hello

  I have a hierarchy with the structures of members following leaves:

  Depending on which division they are ZEN-A, ZEN - B and C ZEN with 7 numbers after them.

  Is there a way to dynamically retrieve the Member in the ZEN-A, ZEN-B and C ZEN in three separate properties so that the user DRG can determine the next member must be added?

  For example, if I have a structure that looks like this:

  ZEN-A0000001

  ZEN-A0000002

  ZEN-A0000003

  ZEN-A0000004

  I want a property which would show the user DRG WHAT ZEN-A0000004 is the largest number so that he or she must insert ZEN-A0000005.

  Thank you!

  Hello

  How do you combine them?

  If something like this ParentABCD-AliasABCD

  Then, you can use the formula Concat to do the same thing:

  Concat ((HierNodePropValue (Hierachy2, ABBREV (), PropValue (Core.ParentName)))-, (HierNodePropValue (Hierachy2, ABBREV (), PropValue (Custom.AliasXXX))))

• Dynamic structures nested

  I'm looking for a way to build a dynamic structure nested in cfscript by using a loop for. Something like:
  < cfset MyStruct = StructNew() >
  < cfset MyStruct ['A'] = StructNew() >
  < cfset MyStruct ["A"] ["B"] = StructNew() >
  < cfset MyStruct ["A"] ["B"] ["C"] = StructNew() >
  < cfset MyStruct ["A"] ["B"] ["C"] ["D"] = StructNew() >
  < cfset MyStruct ["A"] ["B"] ["D"] ['R'] = StructNew() >
  
  The depth of the nesting is unknown, 2 to 1000 and the A, B, C, D, R are all unknown. I have no problem creating the first struct MyStruct ['A'], but can't seem to add the second + nested struct in the first dynamically in my loop. Looks like I want to concatenate each nested struct in the previous structure I.
  
  Any thoughts?
  
  < cfdump var = "#MyStruct #" >

  Hmm... interesting, uh, task. Anyway, is something like what you are looking for. One thing to note, I added a "endOfName" indicator, to indicate if there is a name "Dan" 'Daniel' or 'Fred' and 'Fredrick '.

• dynamic page structure

  Hello
  
  I use ADF 11 g.
  
  I'm trying to set up a page structure that stands out in the order to a logic behind. So, page can have different number of facets, and these aspects should be filled by program. I wonder what is the best method to achieve this. I am trying to use different templates for every possible page structure. But I have a few questions about this, any idea would be appreciated.
  
  1 - is this supported: hand files with a jsp page (which has a side named contentArea), model a jsff file (which has a model of dynamic page reference) included in contentArea.
  
  2. when using dynamic page template binding, it is a requirement that used templates of pages must have the same amount of facetrefs?
  
  3 can dynamically change jsp: include the attribute of 'page' of the tag, for example with the expression language?
  
  4 - How can I find a page (RichPageTemplate component) to support bean template.
  
  
  Thank you.

  Hello

  1 - is this supported: hand files with a jsp page (which has a side named contentArea), model a jsff file (which has a model of dynamic page reference) included in contentArea.

  I tried and it works with the full support of the IDE.

  2. when using dynamic page template binding, it is a requirement that used templates of pages must have the same amount of facetrefs?

  Yes.

  3 can dynamically change jsp: include the attribute of 'page' of the tag, for example with the expression language?

  Include the page is added during compilation tme, no PERIOD. So I don't think that this is possible. However you can dynamically change the contents of . If you need to dynamically change the elements of an EAP, take a look at the dynamic Page template tag in the tag documentation ADF Faces

  4 - How can I find a page (RichPageTemplate component) to support bean template.

  You can start searching for the UIViewRoot or relatve to the container parent, which is af:form. In the latter case, you create a reference of the JSF for the RichForm component binding in the managed bean and then to call getChildren

  for example

      public String cb1_action() {
          // Add event code here...
          List l = form1.getChildren();
  
          for (UIComponent u : l){
              System.out.println("Child "+ u.getId() + "--"+u.getClass());
          }
          return null;
      }
