• The use of variables in the help of timelines

  I wonder how can I use this code for a nav to change the wire and outside the States.

  This line of code works.

  sym.getComposition () .getStage ().getSymbol("Section2") .getSymbol ("map_Popups") .getSymbol ("U SA") .play ("Over");

  I try to save every country in a variable, but do not work.

  sym.setVariable ("current2", "USA");

  sym.getComposition () .getStage ().getSymbol("Section2").getSymbol ("map_Popups") .getSymbol (current2) .play ("over");

  Now you need a getVariable() to read. Try this:

  sym.setVariable ("current2", "USA");

  get the variable

  var newCountry = sym.getVariable ("current2");

  sym.getComposition () .getStage ().getSymbol("Section2").getSymbol ("map_Popups").getSymbol(ne_wCountry).play ("Over");

• LabVIEW: Concerns with local Variables and the readability of the program

  Hello everyone. I was hired for the summer to work at my University to a new laboratory. All right, but I have some problems with my main VI. I am a new user of labview coming from a C++ background. I went through several iterations of adding features, fixing bugs and doing my readable program. Before the last "cleaning" my program was so big that I couldn't see it all at once on my screen. My goal was to solve this problem. My solution contained three parts: use a state machine show parts of my code at the same time, to remove the son as much as possible, and use structures element to position my code manually.

  I met since problems write other programs that brought me here, and I saw a series of messages condemning the new programmers for their use of local variables instead of cables. I do not know my use of structures element as fancy boxes I can exclude the automatic cleaning is also a terrible practice.

  After doing some more reasearch on the subject I see local variables to add the duplicate in memory entries and their suppression can significantly speed up execution time. I have a delay programmed in a part of my code, but the rest can run as fast as he can as far as I'm concerned.

  I have attached my main program. Looking at it I think I did a good job to make it readable. But I'm not a user expert labVIEW.

  How to balance (do not use local variables, these structures element, etc.) efficiency and readability. Before you make these changes, there was so many things and so many threads all over the place that I couldn't even tell what was going on, and even less my teacher. I really wish I could see my entire program without scrolling on this computer of the laboratory (resolution 1280 x 1024).

  Advice on how I can achieve the efficiency, simplicity and common readability would be greatly appreciated. I feel I've done the latter while sacrificing the first two. Ultimately the three should probably be equally important.

  Thank you.

  As said altenbach, attach your event structures.  It should really be only need structure of an event, especially for a simple VI like that (I counted 3).  This is the second time I have recommended this today, but fetch JKI State Machine.  I use as the basis for most of my interfaces.

  Here's a way to manage the break with JKI.

  

  

  

• Is there a way to get refnum one control from a local variable or the wire?

  I'm looking for a way to get the refnum of the element of a façade of a local variable or the wire. Is this possible?

  Is there a way to accomplish the following?  (These are published images, this is currently impossible in LV)

  

  or maybe

  

  If this kind of thing is not possible, is there a reason for this? If there is no reason why it is impossible, I'll put it on the boards of the suggestion.

  Why do you need this?

  A thread is simply data. It is not associated with a control.

  Similarly, a local variable is a way to access the data in a control, for not interacting with the control itself.

  Is the control of the right-click and selecting Create > reference not good enough for you?

  You can write code to get the reference to the controls connected to the cable and the the control whose desired local variable, but I feel that this is not really what you want.

• Can Oracle 10g - I use a variable for the access of the user identifywhat tablesto?

  I have the following code in a trigger (PL/Sql block) of a form:
  
  Select fieldname in user1.sometable myvar;
  
  is it possible to use a variable instead of coding hard "user1"? And on the same subject, this variable would also be declared in the world?
  
  Thanks in advance,
  Darren

  Hello!

  User1 is the owner of the table sometable.

  If only the User1 runs your form, there is no need to put the tableowner in front of the tablename parameter.

  If other users run your form, you must create a public or private (for each user) synonym of this table.
  After that, you don't need to use owner.tablename in your sql statement.

  But:
  You cannot use a variable for the user name without using dynamic sql
  as you do if you create a recordgroup.

  Concerning

• The use of variables in the Calc scripts and business rules

  I'm sure that there have been previous discussions on this topic, but can anyone let me know the benefits of using variables in scripts of Calc and BRs?
  
  Thank you
  A

  I've never used variable Calc and after reading a guide to the study, which has talked about them, I didn't really understand the benefits.

  ^ ^ ^ I use variables all the time to make difficult abstract formulas. Here is an example.

  /*     Declare variables     */
  VAR varSalaryCosts ;
  VAR varProdOHLabXXXX ;
  VAR varXXXX ;
  
  A whole bunch of code here along with very limited FIX statement and then...
  
  "Salaried Labor"
  (
       varSalaryCosts = "Salary Costs"->"No Department"->"No Category"->"Salaried" -
                           "Wage Bonus"->"No Department"->"No Category"->"Salaried" -
                           "YYYY Retention Bonus 40%"->"No Department"->"No Category"->"Salaried" -
                           "YYYY 60% Ret Bonus Accrual"->"No Department"->"No Category"->"Salaried" ;
       varProdOHLabXXXX = "Number of Employees"->"ZZZZDepartments"->"Codes"->"Salaried" +
                           "Number of Employees"->"Blah Departments"->"Codes"->"Salaried" +
                           "Number of Employees"->"Humph Departments"->"Codes"->"Salaried" +
                           "Number of Employees"->"TTTT"->"Codes"->"Salaried" ;
       "Salaried Labor" = varSalaryCosts * ("Number of Employees"->"Salaried" / varProdOHLabXXXX) ;
  )
  

  The last formula is how the formula was described to me by the owner of the company. I find it much easier to read something like:

  "Salaried Labor" = ("Salary Costs"->"No Department"->"No Category"->"Salaried" -
                           "Wage Bonus"->"No Department"->"No Category"->"Salaried" -
                           "YYYY Retention Bonus 40%"->"No Department"->"No Category"->"Salaried" -
                           "YYYY 60% Ret Bonus Accrual"->"No Department"->"No Category"->"Salaried") *
                           ("Number of Employees"->"Salaried" /
                           ("Number of Employees"->"ZZZZDepartments"->"Codes"->"Salaried" +
                           "Number of Employees"->"Blah Departments"->"Codes"->"Salaried" +
                           "Number of Employees"->"Humph Departments"->"Codes"->"Salaried" +
                           "Number of Employees"->"TTTT"->"Codes"->"Salaried")) ;

• How to read the values of the variables of façade in loops without using local variables or property value nodes?

  I know that local variables and nodes of property value are causing a lot of problems.

  But if I read the value of a variable front outside a loop.

  the value is only read once before the start of the loop.

  Changed the front variable values during the iterations of the loop, is invisible.

  How can I solve this problem?

  
  

• Why flatten data chain not getting past all about TestStand via a local variable of the string?

  I tried to go around a series of data in TestStand as a string using "flattened chain" of LabVIEW. When I create a local variable in TestStand of type 'string' and try to write the cluster flattened at this that he simply not transmitted. If I convert the string flat binary table and then pass it around, I can recover all the data very well.

  Is there something I'm missing here?

  I've attached an example Teststand sequence that illustrates this problem. If you run this sequence that the 1st test will fail, which is the attempt to simply pass the flattened string data structure and the 2nd test will pass as it is the binary table that I generated from the flattened string.

  Thank you

  Pete

  crossrulz is correct.  The Null character affects how TestStand handles the string.  You will need to specify the string to a binary string in the list of settings both the VI.  TestStand then encodes the stringso it can prevent the loss of data.

  If you need work on the binary string in TestStand, you will need to convert it to an array of raw data with PropertyObject.GetValBinary.

  

• Using local variables to 'clean up' diagram

  I have attached a photo with red circles indicating my use of local variables to 'clean up' a block diagram. If I meet problems this? I leave this task and the unwired error?

  -Sarah

  I see a few maybe really bad race with your VISA resources conditions.  For example, if the task on 3 is empty (default), it is likely that the local read will happen before the local write.  What this will turn into is lose you your reference VISA in the register shift.  Use threads.  Locals clean up very rarely in your diagram.

• Use of Variables in the statement of sym.play(1000)

  I built a system menu to a main menu with three options and a single submenu animation that should be limited to one of the three different places on the timeline, depending on which is click the main menu button.

  For each button in the main menu, I created a click made up of sym.setVariable event ("Subselection","#" ""); in "#" can be set to 1, 2 or 3.  When you click on one of the buttons on the main menu and the submenu opens at the end of this sequence, I inserted the following text - sym.play(1000) (subquery);

  It is all quite clearly displayed in the snap-in to display annotated below.

  It is important for me to master the use of variables and strings concatenated in the instruction of sym.play(1000) so I can create as compact as possible OAM files, so any help is greatly appreciated.  My guess is that I am a stupid syntax error, but I am not opposed to picking the brains of others when mine is insufficient for the task at hand.

  Thank you very much.

  Andy.

  

  Hi Harley,

  Image labels are 1,2,3 etc.

  sym.setVariable ("Subselection", 0); in the composition of the scene ready

  Then in the menu, you can set the variable "Subselection" 1,2,3 and then call sym.play(1000) (sym.getVariable ("do"));

  Thank you and best regards,

• How to replace the variable with the help OF the operator?

  Hello
  
  I'm creating a form where the user selects the check box which products he wants to see. After the choice, I should show all sales of this product, but the selection does not recognize the variable after the IN operator, for example:
  
  SELECT the product, price, quantity
  FROM the sale
  Product WHERE IN (vcProducts);
  
  Can someone help me?
  
  Cree

  I guess that vcProduct is a varchar2 variable where you have a chain of your prodids, as ' 4711,4712 concatinated, 4713'. May be you have each place value '. Is not the question, which is not part of the sql syntax set. You either have a list of enumeration or a subselect.

  Where do you need it? In the block or Pl/Sql where clause.
  In the latter case, you can configure the list in a variable (with enclosing "") and set the block where property.

  In the first of may by INSTR is useful, INSTR (vcProduct, vcDelim | table.prod_id | vcDelim) > 0. Make sure you have your list attached and separated by the vcDelim. If you prodct table with the number of lines (million), it can be slow because no index will be used.

  Dynamic sql or.
  Or write a subquery und temp-table.

• Use of variable in the For-Each statement

  Hello gurus.
  
  I'm having a problem using a variable, I created in a statement for each. Here is the code I am using
  My goal is to create a variable based on the type of Bill. If the invoice is a proof or a reprint, a copy should be printed. If it's a final bill, I need two copies.
  
  <? xdoxslt:set_variable($_XDOCTX,_'x',_0)? >
  for each<? If: Print_Additional_Header_Text_ID238 = "PROOF"? > <? xdoxslt:set_variable($_XDOCTX,_'x',_1)? > <? end if? >
  <? If: Print_Additional_Header_Text_ID238 = "REPRINT"? > <? xdoxslt:set_variable($_XDOCTX,_'x',_1)? > <? end if? >
  <? : otherwise (Print_Additional_Header_Text_ID238)? > <? xdoxslt:set_variable($_XDOCTX,_'x',2)? > <? end if? >
  <? xdoxslt:get_variable($_XDOCTX,'x')? > <? for-each@section:xdoxslt:foreach_number($_XDOCTX,1,$x,1)? >
  
  foreach is the loop that I use to repeat sections of the Bill.
  
  When I run with the last impression for each preview, I get an error that says "undefined variable: 'x'"»
  But when I remove the last for each good variable, 1 or 2, will show in the invoice.
  
  My question is: How can I use the variable 'x' in <? for-each@section:xdoxslt:foreach_number($_XDOCTX,1,$x,1)? >

• Using of Variable in the filter expression will not scan.

  IN ODI 11.1.1.3.0, I've defined a Variable of type 'Alphanumeric' (SelectionDate), default = January 1, 1970 with the query select: select to_char (SYSDATE, 'DD-MON-YYYY') of double.
  I intend to use this variable as a scenario (parameter) variable that receives a value in the form "DD-MON-YYYY', of the execution environment.
  I refreshed the variable and the value received June 16, 2011 (current date). So far so good.
  
  Then, I defined an Interface and use the variable in a filter expression:
  
  Filter active: checked
  
  Tab implementation:
  SOURCE_VIEW. SELECTION_DATE BETWEEN TO_DATE (' #PROJECT1.) SelectionDate', 'DD-MON-YYYY') AND (TO_DATE (' #PROJECT1.)) SelectionDate', 'DD-MON-YYYY') + 1).
  
  Run on: Source
  
  During the verification of the expression (click the check mark in the application tab) I always get: Expression is not valid for the DBMS. java.sql.SQLDataException: ORA-01858: a non-digit character was found here where was waiting for a digital.
  
  I can't filter to analyze. Thank you for your ideas of what could be wrong.
  
  
  
  Jose.

  Hi Jose,

  You must set this variable in a package and refresh it. Then place your interface with the current filter condition.
  Run the package. It should work.

• Column unresolved when using presentation variable in the filter responses

  Hi all
  
  I am using a dashboard command prompt that sets a variable presentation - pres_year. I use the presentation variable in the filter of the application.
  In the 'Criteria' tab, in the filter for a request, I put a year column (YEAR) the presentation via the Expr Variable variable and enter the variable name of presentation only. End up with:
  YEAR is equal to / is in @{pres_year}
  
  When you use the dashboard, the prompt and ask all work fine. The problem is when I'm in demand for answers and I click on the "View results" button I get the following error:
  "NQSError: 27005 unresolved column pres_year'.
  
  Any suggestions?
  
  Thank you.

  Set a default value after the presentation variable in your filter. If you put no default value, and then in the responses, the application not of value to the variable of presentation. Click on the filter and add default value. Then it won't work.
