• To access the Global Variables in the functions/methods

  Which of the following statements is better in terms of performance and efficiency?

  I saw a lot of guides discourages the use of global variables in the functions/methods, but I just don't understand why anyone would create a copy of the variable, modify this copy and to grant this value to another variable and throw.

  You must create an instance to pass to your function.  the parameter (for example, mov) does not create a separate instance and creates only a temporary pointer to the passed object.

  If an instance is prepared for gc, having spent this instance to any number of methods (as a parameter) delay / will not interfere with ca.

  and Yes.

  MOV ['x'] = mov.x,

  MOV ["rotation"] = MOV.rotation,

  MOV [anypropertystring] = MC.anyproperty

  Flash uses array notation to solve strings into objects:

• How can I build and pass a variable to the function getField?

  I need to know how to build and pass a variable to the function getField():

  I have a form of several sections similar to a spreadsheet.  Each section contains 5 rows of 11 columns.  Currently I have calculations in the field I want to consolidate and move to the level of the document.  The field names in each column are identical except for a row identifier.  For example, in the 1st row: a_debtType1, a_debtTerm1, adebtRate1, etc.  I want to be able to pass to a function of level document line identifier and that connect a function "getField.  Here is an example:

  Document-level:

  function calculateLoan (lineNumber) {}

  var myDate = getField("a_debtType"+lineNumber).valueAsString;

  var myDate = getField("a_debtTerm"+lineNumber).valueAsString;

  .. few treatment

  return

  }

  Level of the form:

  change the information in the form is ready for line 1

  function calculateLoan("1");

  Thanks in advance for any help.

  It seems good except how you call the function of what you have. The calculation script should be something like:

  Custom calculate script

  calculateLoan("1");

  Note that you can also get the line number if it is contained in behalf of the field that calls the script if you don't disturb him passing as parameter, assuming you named the fields correctly.

  For example, to calculate the field is called "row_total.1", you can get the line number in the script like this:

  var no_lig = event.target.name.split(".") [1] ;

• Get the value of the variable inside the function from the event (EventListener)

  How to get the value of the variable inside the function from the event. Variable has been declared as a function of external events.

  var StringVar="sample";
  
  
  
  
  myButton.addEventListener(MouseEvent.CLICK, myClickReaction);
  
  function myClickReaction (e:MouseEvent):void{
  StringVar="other sample";
  }
  
  trace(StringVar); /* it gives me "sample" value and i would get "other sample" value */ 
  

  This strange because if it would be the trace of a normal function would give me good result.

  var StringVar="sample";
  
  
  function myClickReaction():void{
  StringVar="other sample";
  }
  
  myClickReaction();
  trace(StringVar); /* it gives me result as i wanted to have - "other sample" value */ 
  

  I also know method of passing of arguments depending on the event, but it doesn't for me as I would like to

  var StringVar="sample";
  
  
  
  
  myButton.addEventListener(MouseEvent.CLICK, function(e:MouseEvent){ myClickReaction(e, StringVar) },false, 0, true);
  
  function myClickReaction (e:MouseEvent, StrVar:String):void{
  
  StrVar="other sample";
  }
  
  trace(StringVar); /* it also gives me "sample" value and i would get "other sample" value */ 
  

  How to do it correctly?

  I do not know the structure of your screen lists so I can't tell you how to access the variable, but you're on the right track. If it's a parent, then you can always use the .parent property to cross to the top the list display to try to access.

  for example 1 level:

  MovieClip (this.parent). StringVar = "another sample";

  Add more properties .parent to continue to move to the top of the list.

  for example:

  MovieClip (this.parent.parent). StringVar = "another sample";

  Just like always, use traces (MovieClip (this.parent). StringVar); until you get the value that you want to know that you're accessing them correctly.

• using a variable outside the function that defines

  Why can't I not use the variable "numOfItems" outside of the function in the code I have attached below? I need to have a variable that retrieves its value in the number of nodes in an xml document and used later to the timeline root, outside the service the xml onLoad, once it has been loaded.
  
  
  
  

  You are still facing the same problem.

  Track at the bottom of your code tries to trace before your xml file has finished loading. Therefore, you have to wait as well.

  Inside your onLoad

  traceResult();

  And where you have your current track down.

  function traceResult() {}
  trace (numOfItems);
  }

  That should do it.

• store internal variables in the nodes mathscript/scilab

  Is it possible to store the values of local variables in mathscript node? Maybe have an initialization section where variables are implemented and then later updated. And then something to reset the closure of the vi? Im guessing not, im guessing that we must do the same as labview, pass new releases at the entrances, but it is much more natural in a text based language to do it this way (for me anyway).

  Gordal salvation,

  You can use the backup and loading of orders to store variables for your scripts in a file.  Note that these commands will a warning glyph occur which reduces performance, so what I propose is the following:

• Cannot set HScrollBar & quot; Scroll & quot; variable inside the function in & lt; MX:script & gt;

  Why can I not pay the scrolling feature for a bar scrolling from a function. It can be hard coded and not dynamically set. This makes it difficult to make the scroll bars on the fly.
  
  I want to do the following:
  var myBar:HScrollBar = new HScrollBar();
  myBar.scroll = "myFunction (); « ;
  
  BUIT, it is said that myBar doesn't have a variable named scroll. What is the problem?

  Hi, Creo, 'scroll' is not a property of the ScrollBar class, this is an event. To do what you're trying to do, you add a listener of events, something like this:

  Import mx.events.ScrollEvent;
  var myBar:HScrollBar = new HScrollBar;
  myBar.addEventListener (ScrollEvent.SCROLL, myFunction);

  I hope this helps. -Bruce

• MAXL: Error when you use the runtimesubvar variable in the function 'run the calculation '.

  Hello everyone,

  I am trying to use a variable ($MyScenario) as a runtimesubvar for a calculation script.

  This excerpt from my script works perfectly (without variables):

  run the calculation "MyApp". "MyPlantype'. '" MyCalcscript' with runtimesubvars ' MyRTSV = 'Budget '. ' ;

  The following with variable does not work:

  The value MyScenario = "Budget";

  echo $MyScenario;

  run the calculationn 'MyApp'.' MyPlantype'. 'MyCalcscript' with runtimesubvars ' MyRTSV = $MyScenario; ' ;

  
  

  It is the output:
  

  Budget (<-$MyScenario echo works!)

  MAXL > run the calculation 'MyApp'.' MyPlantype'. 'MyCalcscript' with runtimesubvars 'MyRTSV = $MyScenario;';

  ERROR - 1012150 - environment variable [MyScenario] does not exist...

  I also tried putting $MyScenario between quotation marks simple '$MyScenario', which seems to work better but leading to a different error:

  Budget

  MAXL > run the calculation 'MyApp'.' MyPlantype'. 'MyCalcscript' with runtimesubvars ' MyRTSV = 'Budget';

  ERROR - syntax error 1242021-1 ['Budget'].

  What Miss me?

  Thanks in advance,

  Fadel

  Have you tried to use double quotes around the entire string of RTSV? Apostrophes are cutting the expansion of variables in MaxL. I think the idea is at the exit of the second snippet - $MyScenario is passed through the intact calculation and then script (MIS-) interpreted as an environment variable.

• Get the variables of a function

  Hello

  In order to reduce the use of the event of calculation in a repetitive subform, I've implemented a function (riskRating) in a script object (calculateRisk), who calls the output of a drop-down list (RA_severity) event.

  It is the Javascript in the exit event...

  var vLikelihood = RA_likelihood.rawValue; Combo 1
  var vSeverity = RA_severity.rawValue; combo 2
  var vRisk;

  calculateRisk.riskRating (vLikelihood, vSeverity);

  Console.println ("risk after function =" + vRisk);

  RA_risk_rating. RawValue = vRisk;  This line is intended to affect the value of the function vRisk in another discipline (but is not)

  It is the function within the script calculateRisk object...

  function riskRating (vLikelihood, vSeverity)
  {

  var vRisk;

  If (vLikelihood == null & & vSeverity == null)
  {
  vRisk = null;
  }

  on the other
  {
  vRisk = vLikelihood * vSeverity;
  }
  
  Console.println ("risk inside the function =" + vRisk);
  
  Return vRisk;
  
  }

  I tried different approaches to get the response from the service and to serve for the rest of the script in the script to output event.

  The console are the correct calculation of the function, but it is not updated the variable outside the function.

  Any ideas?

  Thank you

  Niall

  

  Niall,

  Take a look at the attachment. The form contains four numeric fields: 'a', 'b', 'total' and 'other '. This a calculation field 'a' and 'b '. On the output of 'b' event, it calls "addNumbers()' in 'MyScriptObject '. The function 'total' updates and returns the value of 'total' to be linked to 'other '.

  Form1.Page1.Subform1.b::exit - (JavaScript, client)

  other.rawValue = MyScriptObject.addNumbers (a, b, total);

  Form1. #variables [0]. MyScriptObject - (JavaScript, client)

  function addNumbers (a_, b_, total_) {}
  return (total_.rawValue = a_.rawValue + b_.rawValue);
  }

  -What are you looking for?

• Referencing variables in a function without causing 'access undefined... '. "

  I have a function called once creates new variables

  function createPane(event:Event):void
  {
       var manager:IPaneManager = map.getPaneManager();
       var markerPane:IPane = manager.getPaneById(1);
       var markerIndex:int = manager.getPaneIndex(markerPane);
       var pane:IPane = manager.createPane(markerIndex);
  }
  

  I have another function that refers to some of the variables created in the function above

  function paneClear(e:MouseEvent):void
  {
       manager.removePane(pane); 
  }
  

  If I have both in my code, FLASH will throw an error because the variable Manager and the pane are not created until the createPane function is called.  I understand that if I created these variables outside a function, this error does not happen, but this isn't an option that I have to wait to call createPane.

  I also found that if I embed the function of paneClear within the createPane function, I will not get an error (see below).  I thought that the nesting of functions is bad practice, so I'm Director of this approach.

  function createPane(event:Event):void
  {
       var manager:IPaneManager = map.getPaneManager();
       var markerPane:IPane = manager.getPaneById(1);
       var markerIndex:int = manager.getPaneIndex(markerPane);
       var pane:IPane = manager.createPane(markerIndex);
            function paneClear(e:MouseEvent):void{
            manager.removePane(pane); 
            }
  }
  

  I hope this explains my situation clearly.  I'm just trying to understand how you can reference a variable in a function, even if this variable has not yet been created.

  Thanks in advance,

  Josh

  What you would normally do, is to declare the variable outside the function and assign the value inside...

  var Manager: IPaneManager;
  var markerPane:IPane;
  var markerIndex:int;
  var component: IPane;

  function createPane(event:Event):void
  {
  Director = map.getPaneManager ();
  markerPane = manager.getPaneById (1);
  markerIndex:int = manager.getPaneIndex (markerPane);
  component = manager.createPane (markerIndex);
  }

• Return by using the function number

  How can I return number using the function.
  
  Here is my procedure but do not in the name of variable or setting up as a variable...
  
  create or replace function Calculate_number)
  Number 1 in number,
  Number2 number)
  Return number is
  Start
  declare
  number of result;
  
  Select number1 + number2 as a result of double;
  
  
  Return (result);
  end;

  Hello

  You have not need double a lot in PL/SQL.

  CREATE OR REPLACE FUNCTION Calculate_number
  (
       number1 IN NUMBER,
       number2 IN NUMBER
  )
  RETURN NUMBER
  DETERMINISTIC
  IS
         result number;
  BEGIN
       result := number1 + number2;
  
       RETURN Result;
  END      Calculate_number;
  

  Strored procedures, local variables are declared between statements IS and BEGIN. DECLARE in a stored procedure starts a nested block to BEGIN, with its own local variables, which is rarely necessary. (Nested BEGIN blocks are not so rare, but they almost never have local variables need a nested block. Most people here all variables of the function complete together before the first START.)

  If the function always returns the same value when it is called with the same arguments, then Deniz it as DETERMINISTIC; It might make it faster to use.

  There are many good reasons to use a variable as results, but if you don't happen to have one, then you can do this:

  CREATE OR REPLACE FUNCTION Calculate_number
  (
       number1 IN NUMBER,
       number2 IN NUMBER
  )
  RETURN NUMBER
  DETERMINISTIC
  IS
  BEGIN
       RETURN  number1 + number2;
  END      Calculate_number;

• Function of memory in the loop control and Simulation - problem of the ODE Solver

  Hello

  I'm correctly using the control loop & simulation to simulate the behavior of what is essentially a shock absorber-spring-mass system. In the process of change in time (dt) is used to integrate an arbitrary value. I use a rack depending on memory to store the time, to calculate the change of time (dt).

  The simulation is quite complex, because of the precision required, not all the ODE solvers can all support. Currently I use the Adams-Moulton method, this works very well for the simulation. However, it cannot detect the change in time, the change is constantly zero. This problem has auto market by using an another ODE Solver, but then the simulation has been messed up instead (even when I listen to the step sizes and tolerances). So I'm pretty confident that Adams-Moulton is one of solver ODE best suited to the problem at hand.

  Is there another way to store the previous hour and use it calculate lag, that the use of the memory function? Everyone knows about these problems before?

  I did a lot of research of error using the probe, but I'm sure that there is a problem with the ODE Solver and memory function. See the image below, showing basic how is calculated the change in time.

  I'm pretty new to LabVIEW, so if there is something else I missed I would be happy to hear it.

  PS! I set the tolerance minimum step of size/relative and absolute for the Adams-Moulton to simulate the behavior of the system properly.

  Problem solved!

  It turns out that the ODE Solver has struggled because of two "table 2D find" used functions. This was created for the interpolation/extrapolation, which caused a problem constantly and the ODE Solver could not resolve correctly, so the functions of memory doesn't work does not correctly or the other.

  By increasing the table manually, I could use closest method instead, with also good results as interpolation.

• First HP: Solve the function

  Hi, I am using the function solve with next funtion

  

  I don't have the result, unless I have change the variable p, in a TI Nspire I have the answer:

  

  Hello

  In response to the question "Why can't the first do but TI" I would answer by saying: "why don't the nspire integrate ln (x) * sin (x)?"

  In short, the SCA in the flower of HP argues (highly questionable correct in his belief too) that implement a third command exact equation is of real practical use and therefore did not implement in the CASE. I would personally like to see in there, but since I'm not yet qualified to write this code... :-/

  The nspire case cannot handle this integral at all in exact form. Does this mean it is defective or buggy? Or just a piece of mathematical abilities has not implemented?

  The CASE in the Nspire was strongly resolved to return 'Manual of nice' results, but isn't really manage math much higher level at all. Etc's first good enough otherwise. It took a lot less time focused on the return of "nice" results and more time spent on things of higher mathematics and mathematical accuracy.

  The other difference is that the CASE in the Nspire has not fundamentally changed since bought TI derive in 1995, or whenever it was. The etc first is under active development to add new features, improve and become more powerful and better over time.
