Variable references to objects

• Reference the object expected found execution

  I have a .NET DLL that has a method that takes a parameter of reference an object of type NationalInstruments.TestStand.Interop.API.Execution. In TestStand 4.2.1 it worked well if I spent it RunState.Execution.

  Now in 2010 TestStand I get an error in TestStand that the method expects an object reference, but found a writ of execution. A performance, that's what I want is what describes the method. Then, why this doesn't work?

  Anyone have any ideas?

  Thank you.

  Skeptical salvation,

  It is a known backwards compatibility problem introduced in 2010 TestStand and will be fixed in a later version.

  That said, is not really meaningful for the parameter as byref (i.e. input/output) in this case, execution is already a type of reference data interface. Thus, passing byref implies that the method has the possibility of replacing the object that points to RunState.Execution with another object of execution that very probably is not something of the method would make ever.

  To work around this problem, you can do the following:

  (1) changing the prototype of the method (or add a new overload) to take the run by value setting (i.e. only), which is probably what that the author of the code really the intention anyway.

  Or

  (2) create a local variable of type object reference and assign RunState.Execution before your call to the method, and then pass the local variable for the byref parameter.

  Please let us know if you have any questions or if workarounds are not enough for you.

  Hope this helps,

• Forbidden: Variables of level object in the event handlers?

  Hello world

  So I thought I had a pretty good handle on works the scope in Java, but for some reason any that a sentence in the Identity development documentation Manager is causing scratching me my head:

  28.3.1.1 development considerations

  [...]

  
  

  * Do not set the object level variables in the event handler.

  What exactly do you think they mean by that? Are we supposed to initialize variables, avoid new methods?

  All instance variables? I mean, that cannot be because how you can write useful code without instance variables?

  Or is it just an injunction on the locking and safety of threads?

  Thanks in advance!

  -Mark

  Here object variable average instantiate every variable which is at the level of the object.

  This is the reason for this:

  Once in the case of recon user gets into the loop to break out of loop only when the reconciliation of the users is made and so if you have instantiated any variable to the object variable and then after a user the value of this object will not get instantiated and will choose ythe value what first user changed.

• Get the reference to object to new

  Hello

  I'm testing a few notions of running in parallel of the different tests in parallel on a single Instrument. The idea is to start multiple tests as sequence called for further discussions as in the ParallelExecution.seq example provided with the test bench. The wait later in the code function also has the option 'Specify by reference to the performance object', but I haven't figured out but how get this reference...

  Is there an easy way?

  See you soon

  Oli

  Oli,

  simple answer. When the configuration of the SequenceCall step to "New discussion", the "tool button" next to the right of the combobox control is enabled (sequence call Advanced Settings).

  Press the key.

• Unidentified for reference ActiveX object

  There are objects in the examples following that I can't identify (the program was written by someone else).

  There are labeled WINX32Lib.IExpSetup and pFile on the block diagram. There's obviously static ActiveX references, but the contextual help of Labview said "no description available".
  What do these, and how to create them in the palette of functions?

  calvintiger wrote:

  They were in fact part of the Winview (used for scientific CCD cameras).

  Do you know how to create these items on the block diagram?

  

  I admitted little knowledge or not and you think I can help it Fund?

  I'll take the complement and offer what I can in Exchange.

  Start by droping a container ActiveX on the FP.

  Right click and find an option to navigate (or something like that).

  There may be an option to "Create from the document" available for ActiveX stuff.

  In the case of navigation find something that looks like what you want (with the help files you will have to explore).

  After choosing the AX thingy, go to the BD and start adding nodes of property or invoke nodes and see what you find.

  I don't know if this will help. That's what I would do if I found myself trying to create code using undocumented stuff AX.

  It would be interesting to link to serach for help on the web for the AX.

  You COULD also just drag the code that you have demonstrated a new schema and there is.

  Made with the specualtion!

  Have fun!

• Getting a shared list of variable references

  I'm working on a project of data acquisition that will use AES. This is really my first foray in EVS, and I hit a stumbling block.

  I'll use a loop for distributing the waveforms acquired at their appropriate variables (DAQmx read Nsamples, Nchannels, 1 d of DBL waveforms, each waveform of the GET it's own variable.) "Get Shared Variable List" returns a list of variable names, but the Variable 'write' requires a reference to a variable. How can I go from one to the other?

  I've posted an excerpt of what I have so far.

  -Ian

  It seems that you're dealing with two categories of variables.  The origin of the palette of DSC function and returns what looks like an array of labels of DSC.

  The purple thread says it's a network variable (tag BV), but the hook upwards a property to that node and the class is SharedVariable IO.

  Your other function leaves the Variable Communication/Shared Data palette and just says it is a variable.

  I'm not sure it would work as I have no way to test it.  But if you use the node name property of the SDC tag and use it to open a reference to a shared variable, the son all connect without errors.

  

• Functional Global Variable reference

  Hi all

  I want to update the value of the indicator element in primary VI, I don't want to use the global variable, due to the problem of race condition. So I create a functional global variable to control reference. It is reliable and can avoid the race condition critical?

  I have attached two Test VI.

  Thanks for your advice.

  Personally, I use user events to send data to the main VI and then he can update the indicator.  This generally works very well since most GUI screws using a Structure of the event anyway.

• Variable number of objects detected in Calculator handling VBAI

  I have an inspection looking for shiny objects (holes) in a product, and in general it is not all (good), but when he does I need to know the location of each hole, to determine the xy-limits of the area of holes, that is, the minutes and culminates each hole xy coordinates. To do this, I would use a stage of caclulator and iterate through all of the holes found... but I don't think that the calculator can handle a variable number of holes... or it can?

  Thank you

  Eric

  Hi Eric,.

  Step of the calculator does not support tables. We have had many requests on the better table support in VBAI and we are going to solve it.

  In the meantime, you can browse the results of a step that produces berries by building a state diagram a bit more complex. Index Example.vbai measures and classify objects Example.vbai for examples on how to do it.

  I hope this helps.

• 1009 error for reference of object null-how fix/workaround solution?

  Hello

  There, with the help on the forum, worked on a script (AS3) for a tween animation show breathing in and out for a year of e-learning courses. There are buttons to pause and cancel the pause/resume the animation.

  These functions of pause and cancel the pause/repeat up a 1009 error if you click on the button break for time interpolation is the evolution of the expansion to the contractors. Thus, most of the time, no error. But every so often, if you click on the turn, the 1009 error when debugging.

  The error points to the line: _paused == null? pauseAnimation():unpauseAnimation(); as part of one of the functions pause. And the error points also to a conditional in a second pause feature which is probably the beginning of the attempt to run the script in him: if (_tX.isPlaying) {}

  I tried different ways to change the script but cannot prevent the error. Any help would be appreciated.

  I've included the complete pause below feature script:

  // pause/unpause
  function pauseButtonClick2(e:MouseEvent):void {
      _paused == null ? pauseAnimation():unpauseAnimation(); error 1009
  } 
  // pause
  function pauseAnimation():void { 
      // if Tween _tX is running
      if (_inhale) { //error 1009
          // stop the Tween        
          _tX.stop();
          _soundChannel.stop(); //soundChannel playing inhale sound mp3
           _exitButton.visible = false
          indexBtn2.visible = false;
          // record what is paused
          _paused = "tween";
  
      } if (!_inhale) {        
          _tX.stop();
          _soundChannel.stop(); //soundChannel playing exhale sound mp3
          _exitButton.visible = false
          indexBtn2.visible = false; 
          // record what is paused
          _paused = "tween2";        
      }
          else{
          // timer is running
          // stop the timer
          _timer.stop();
          exitButton.visible = false

      _exitButton.visible = false;
      indexBtn2.visible = false;
      _resumeButton2.visible = false;

  It makes more sense.

  Replace your if statement (_inhale) with:

  if (_inhale&&_tX) {

• Syntax of variables reference?

  I have a large table I want to filter on any field. I have the dataProvider array and the field names in a variable.  Can someone point me in the right direction on how to set up a dynamic filter, all I can find are static item.arrayLabel into a filterFunction function where the order of the day is the dataProvider and arrayLabel is the "column" (item.city or hand point element [fieldName] where fieldname can be 'data' or 'label').  My ultimate goal is to eliminate [object Object] in the list, if there are NULL items in the database for this fieldname.  Any help is appreciated.

  If you have items of data such as

  dataProvider =

  [

  {City: "San Francisco", State: "CA"},

  {City: null, State: "CA"}

  ];

  and a fieldName as

  fieldName = "City";

  then a filter as function

  return item [fieldName]! = null

  to let pass only the elements whose field of the city is null.

• Use variables to display object in Captivate 4

  I would like to be able to display a check mark next to title on the table of contents page once the user displays the last page in the section.  Is it possible that I can do this, and where can I find the code?

  Thank you

  You can use variables to show/hide elements on a page.

  First add custom variables to represent the State of completion of each section. Something like sectionOneCompleted = 0, sectionTwoCompleted = 0, etc..

  Then add assignments for each of your variables at the end of each section. For example, you could define "on slide enter ' use 'assign' and give variable sectionOneCompleted set to 1.

  Then in your table of contents you can show/hide the elements on the page depending on the value of your new user-defined variables.

  1. go in the slide properties

  2. under ' Navigation: on the slide, type ' select 'execute the Advanced Action '.

  3. click on the... button next to 'the Action '.

  4. under change/create an Action, select 'create '.

  5. the action of giving a name such as ShowHideThingie

  6. in the area of large text, double-click the text of 'Statement add' light gray.  Gray 'add a statement' become a red "declaration". Double-click it again.

  7. Select 'condition' in the menu drop-down

  8. click 'Select a variable' and choose your variable defined by the user (in this case, "sectionOneCompleted")

  9. choose "is equal to" and then enter a value of 1

  10. then, you must specify what to do if the value is 1.  Under 'start' double-click 'Add education '. Select 'action Standard' in the menu dropdown.

  11. Select 'View', then select the name of the object that you want to display (each item placed on the blade has a unique ID)

  12. now, we need to specify what happens if the value is NOT 1.  Under 'otherwise... start', double click 'Add education '. Select 'action Standard' in the menu dropdown.

  13. Select 'Hide', and then select the name of the object that you are showing to step 12.

  14. click "Save" and close the window of the Actions dialogue box.

  This should be it!

  Note: I have not tested these steps carefully (written very quickly), but I hope you get the idea and can get out of here.

• Can a form variable contain an object complex javascript?

  I have a method in a script object fragmentScript that creates an object of javascript to format as below:
  
  customerObject
  name [string]
  address [string]
  City [string]
  State [string]
  List of accounts [table]
  
  When the script is done running, the subform that contains the script becomes hidden and must pass the object to another subform that becomes visible.
  
  I can pass this object via a form variable (located in the file-properties, Variables tab form)?  In other words, a form variable can contain a complex javascript object?

  Thank you

  Hi Elaine,.

  The tempRetCust variable seems to be assigned twice, one assigns an XFA object (with a value property) the other he attributed to a string (without a value property).  So I think that eval (tempRetCust) will work, eval (tempRetCust.value) would be the same as eval (undefined).

• Problems of variable references

  Hello!
  I have big problems referencing variables in Flash! It turns out that there is no way to reference a variable (whether any type) that is declared in the timeline to the current relative... :(
  My setup is as follows: I have a couple of nested clips... I declared a variable (of type Boolean, say) on the stage. Trying to reference it via stage.bVariable , I get an error message saying that I am now making reference to an undefined property, yet it is very well defined.
  Yes, is there a way to make this simple operation? ... :(
  Thank you in advance!

  You can try:

  .bVariable (this.parent as MovieClip) =...

  adding .parent references as in "this" as necessary to return to the main timeline.

  I'll keep an eye on this one to see if a better answer appears. I had similar problems a few weeks (talking to/from nested stuff), and my ad met someone telling me to look thru Flash help without specific reference. I found the solution parent via a web site that answered the question "what happened to my _parents '.

• How to reference an object in a cluster?

  I have a cluster that contains a few digital paintings and several Boolean.  I would like to connect a single reference for the entire cluster to a Subvi and have the Subvi individually controll Boolean values.  How this is done?  I worked with specfic opbject references but I don't know how to work with references within the groups.  I'm under the impression that this has something to do with the strict property nodes but I'm stuck on his approach.  I'm using Win - XP and LV 2009 SP1.

  Thank you

• programmatically set the bind view variable value of object that showed to the query Panel

  Hello

  I have a case in 11.1.1.7 Jdev, I deploy my application on BPM 11.1.1.7.

  I have a VO that three attributes of it was put in a viewcriteria... Let's attribute A1, A2, and A3. the view criteria is any condition "AND".

  and then I create a variable binding in the VO named b. my vo also query using this variable B.

  in the jspx, I create a query panel based on the viewcriteria. then in the A1, A2, A3 and B query pane shows.

  I can reset the Panel request programmatically using this tutorial http://www.jobinesh.com/2011/04/programmatically-resetting-and-search.html

  but unfortunately he didn't succeed for A1, A2, A3 because they are in the display criteria, but B can't reset.

  I tried to put the value programmatically using queryModel, queryDescriptor, setNamedWhereClauseParam, but this failed and it starts to makes me crazy...

  anyone here seen cases like me? and found the workaround? pls throw some light.

  Thank you
