A global variable is adjustable, and a Boolean value in LV3.1.1?

Similar Questions

• Indicator of confused and stubborn Boolean values

  I have a DAQ VI with two problems:

  1. I tried to connect a comparator in a light but Labview tells me "You have connected two terminals of different types," despite them both being Boolean. Maybe the problem is that the source is a table? To fix it, I tried to use a ' x > y?' flag instead, which thread was pleased, but does not really seem to work.

  2. I have a wired graphical indicator to channel ai4 in my block diagram, but the graph on the front label implies that the graph it's cable channel ai5. Maybe that relate to this problem? Taking note of the value may be, it's that all my chart by default flags to draw the waveforms of the next lowest channel when not connected to a source of real tension.

  Screenshot attached. Would be recognizing all of the help that comes my way!

  1. you must remove the values Y of the waveform and find the MAX of the table.  That you will get a unique value that you can compare 1.5

  2 - your index is messed up on your table to index VI.  You missed 4.

• Global variables and the applications

  Version of the APEX = 4
  -DB version and edition = 10g
  -Web server architecture = SST
  -Browsers = IE 8
  -Theme = 5 # Opal
  -Models
  -Region/process type
  
  I need to run a report (not a report of the apex, but a report produced in annother (reporting services) technology) that can be executed by calling a url. I'll have different environments (dev, ft, ut, prod) so I feel the application needs to know what environment is running. The only way I can think to do this is to know what workspace I'm running in. I how I determine this code, is there I can refer to a variable of apex.
  
  Also a global variable is adjustable in the apex? If so it is defined on the homepage?
  
  Any help would be appreciated.
  
  Thank you

  The only way I can think to do this is to know what workspace I'm running in. I how I determine this code, is there I can refer to a variable of apex.

  This can be done by using the views of APEX:

  select workspace_id, workspace
  from apex_workspaces
  where workspace_id = v('WORKSPACE_ID')
  

  Also a global variable is adjustable in the apex? If so it is defined on the homepage?

  Normally it would be a part of the application, defined using a calculation of the Application.

• I don't get to use the global variable. Take a look in my form, please.

  Hello.

  I'm ashamed. I'm not able to use a base on the LiveCyle feature: Global Variable / object.

  I have a textfield for the user to put your name. Then, the user must click at the base. His name and value must be of value to a global variable, then I would use this value in any form.

  This look at my example I would use this value.

  https://Acrobat.com/#d=k0YlC1MXEdVTh1g2TXAJxw

  What is the error? I tried to put as a global variable, but it does not work.

  PS: Call of the value using textfield (TextField.rawValue = TextField2.rawValue), it works fine, but I prefer to use the variable

  Thank you very much.

  Hi Rafael,.

  I'm good thanks

  I do not know if I understood the question, but I think you're asking if it is possible to have a field that displays the value of a global variable (i.e. the 'view' you refer to), which is updated automatically via scripts of calculation or similar to but not dependent on another event, such as 'click '.

  In my view, using a linked across the object world is the only way, and you are right - it is certainly easier.

  Please let me know if I've not understood the question

  Thank you

• Files of Global Variables

  Anyone know which files are used for global variables?
  
  I found a - rhvariable.apj-, but there must be another (or more).
  
  Here's my problem: developers should be able to access and modify these files without going into HR.
  
  I entered rhvariable.apj, change the value of a variable, open HR and the new value was NOT displayed. Yet, when I reopen it rhvariable.apj, it still contains the new value of the variable I changed (I changed the 'certificate' to "Hello" and "Hello" was still the value of the variable. This leads me to believe that there is another file that I need to change because HR does not 'Hello' as the new value.

  I must say that in this case, Peter and well-nonymous answers are correct.

• Global Variable issue

  Hi all
  I need to know to check if the global variable exists or not?
  
  example:
  
  If: global.test exists, then
  do something;
  end if;

  one way is to use Default_value integrated to the global variable to assign them values... If global is already oracle will not set a value, but if not output oracle will create a global variable for you

  Default_value integrated Description copies a value in a specified variable if the current value of the variable is NULL.
  If the current value of the variable is not NULL, DEFAULT_VALUE don't > nothing. Therefore, for text elements this integrated works identically to the use
  integrated in the COPY on a NULL element. If the variable is a global variable undefined, Oracle Forms creates the variable.
  Syntax
  PROCEDURE DEFAULT_VALUE (value_string VARCHAR2, variable_name VARCHAR2);
  Unrestricted integrated Type procedure

  /*** Built-in: DEFAULT_VALUE ** Example: Make sure a Global variable is defined by ** assigning some value to it with Default_Value */
  BEGIN
  /* ** Default the value of GLOBAL.Command_Indicator if it is ** NULL or does not exist. */
  Default_Value('***','global.command_indicator'); 
  
  /* ** If the global variable equals the string we defaulted ** it to above, then it must have not existed before */ 
  
  IF :Global.Command_Indicator = '***' THEN
  Message('You must call this screen from the Main Menu');
  RAISE Form_Trigger_Failure;
  END IF;
  END;

• DLL and global variables

  OK, here's a strange problem.  I am very new to create the dll, so I don't know that I have just an installation problem.

  But I'm trying to pass a global variable of a host program to its attached DLL.  I got this job when I was the CVI 2014. I recently upgraded to 2015 and then started getting "undefined symbols" errors.  With some struggle I managed to compile again, but broke the variable connection in the process.

  I have compiled my DLL in debug mode so that I walk in from the test project.  Right now, my global variable exists in the test project, as well as in the DLL.

  Can I export the variable and the use of DLLIMPORT/DLLEXPORT?  Confused and curiously not to find anyone quite like this on the forums.

  EDIT: this post stack overflow described pretty well from my experience.  I am linking statically.

  Well, what do you know?  I found my problem.  This draft article and example WERE vital to the solution.  This article called, "using the Export method qualifier"was also useful.  I'll cut to the Chase...

  If you use a qualifier of export on the definition and the import on the declaration, LabWindows/CVI identifier export symbol.

  This is the right key.

  So in my example, it should look like this:

  DLL fichier.c

  int DLLEXPORT varName = 0;

  Header.h DLL

  int DLLIMPORT varName;

  Project that uses DLL.c

  #include "header.h DLL.
  
  varName! = 1 ;  a method to change this variable for local use

  Pretty easy, huh?  But wow, it took some time to find.

• Get local and global variables using API

  Hi, I do in LV a Publisher for TS. The user should be able to change the value of global variables and the inhabitants of file. Using the TS API, it is possible to get all files of Globals and locals without knowing the name of these variables have ts? I mean, if I knew the name I could use the value of property Get with the search string. But if the I do not know the name of the variable, can I get the list (and their values) of the variable?

  Thank you very much.

  Use GetNthSubProperty to get sub properties using the index starting with 0 to GetNumSubProperties-1

  Use the Name property to get the name of the subproperty.

• global variable functional to read and write data from and to the parallel loops

  Hello!

  Here is the following situation: I have 3 parallel while loops. I have the fire at the same time. The first loop reads the data from GPIB instruments. Second readers PID powered analog output card (software waveform static timed, cc. Update 3 seconds interval) with DAQmx features. The third argument stores the data in the case of certain conditions to the PDM file.

  I create a functional global variable (FGV) with write and read options containing the measured data (30 double CC in cluster). So when I get a new reading of the GPIB loop, I put the new values in the FGV.

  In parallel loops, I read the FGV when necessary. I know that, I just create a race condition, because when one of the loops reads or writes data in the FGV, no other loops can access, while they hold their race until the loop of winner completed his reading or writing on it.

  In my case, it is not a problem of losing data measured, and also a few short drapes in some loops are okey. (data measured, including the temperature values, used in the loop of PID and the loop to save file, the system also has constants for a significant period, is not a problem if the PID loop reads sometimes on values previous to the FGV in case if he won the race)

  What is a "barbarian way" to make such a code? (later, I want to give a good GUI to my code, so probably I would have to use some sort of event management,...)

  If you recommend something more elegant, please give me some links where I can learn more.

  I started to read and learn to try to expand my little knowledge in LabView, but to me, it seems I can find examples really pro and documents (http://expressionflow.com/2007/10/01/labview-queued-state-machine-architecture/ , http://forums.ni.com/t5/LabVIEW/Community-Nugget-2009-03-13-An-Event-based-messageing-framework/m-p/... ) and really simple, but not in the "middle range". This forum and other sources of NEITHER are really good, but I want to swim in a huge "info-ocean", without guidance...

  I'm after course 1 Core and Core 2, do you know that some free educational material that is based on these? (to say something 'intermediary'...)

  Thank you very much!

  I would use queues instead of a FGV in this particular case.

  A driving force that would provide a signal saying that the data is ready, you can change your FGV readme...  And maybe have an array of clusters to hold values more waiting to be read, etc...  Things get complicated...

  A queue however will do nicely.  You may have an understanding of producer/consumer.  You will need to do maybe not this 3rd loop.  If install you a state machine, which has (among other States): wait for the data (that is where the queue is read), writing to a file, disk PID.

  Your state of inactivity would be the "waiting for data".

  The PID is dependent on the data?  Otherwise it must operate its own, and Yes, you may have a loop for it.  Should run at a different rate from the loop reading data, you may have a different queue or other means for transmitting data to this loop.

  Another tip would be to define the State of PID as the default state and check for new data at regular intervals, thus reducing to 2 loops (producer / consumer).  The new data would be shared on the wires using a shift register.

  There are many tricks.  However, I would not recommend using a basic FGV as your solution.  An Action Engine, would be okay if it includes a mechanism to flag what data has been read (ie index, etc) or once the data has been read, it is deleted from the AE. 
  
  
  There are many ways to implement a solution, you just have to pick the right one that will avoid loosing data.
  

• Global variable control and simulation

  Hello!

  I have a probem with the export data of the Simulation loop in the graphic form.

  I have created a global variable, but in the façade is not updated or exported the data necessary, but in the file as a global variable do?

  I would like to gather (gathering) all the data after the simulation data file as Excel (trace the export data to Excel or save the spreadsheet file) as well as the image of terminal.

  Please find attached my files - someone has an idea or a solution?

  There must be some easy trick

  Thank you!

  (1) why are you doing this problem much more complex it must be using a global variable and another loop like that?

  (2) why you son of path of the VI in the picture? You try to crush the VI on disc with the image?

  (3) be careful not to ignore the output error.

  The code shown in the attached screenshot works very well. I'll take Bravo if it helped you.

  

• APEX 4.2 translate data 'function and Global Variable declaration '.

  Hello everyone,
  
  I use APEX 4.2.1.00.08 and I wonder if there is a way to translate "Function and Global Variable declaration" textarea. Any other script text box is available for translation, but not this one.
  I know what the code is loaded on the header, but may contain important alert messages of global functions.
  
  Thanks in advance.

  Hi Grandmaster,

  "Function and global variables declaration" contains the JavaScript code, that is why it is not wise to include in the standard translation process.

  In my opinion, you have several options to access your translated messages:

  -) Use Application-> Substitutions or
  -) Store your message in the form of component shared-> SMS and and assign it to an application with the APEX_LANG element. Api MESSAGE (http://docs.oracle.com/cd/E37097_01/doc/doc.42/e35127/apex_lang.htm#CHDBCEAB)

  In 'Function and Global Variable declaration' use substitution syntax to replace the value. For example:

  var myDeleteMessage = "&G_MY_DELETE_MESSAGE.";
  ...
  alert(myDeleteMessage);
  

  where G_MY_DELETE_MESSAGE would be a part of the application or the request for Substitution.

• Global variables and for loops

  Hello
  
  I am working on my project for my programming course (a game of Connect 4) and am now in gritty step to rewrite all the code to make look it somewhat professional. Was it the original... disaster: http://zephyr.pastebin.com/7kfyaMRY--Oui, I know who will probably do someone of you cringe. I try to avoid the massive chain of JPanel panelXxY = new JButton(""); using loops for. I need to keep global variables so that I can call in my actionPerformed method, but apparently you can not put a loop outside of a method or main and even if you could, apparently all variables declared in a for loop said would not exist outside this loop. So, any suggestions? Keep in mind that I only knew even what a string for all... 10 weeks, so please nothing too complicated.
  
  Thank you ~.

  See the following for some ideas:
  Update of textFields via a For loop

  To Connect-4, you can use a two-dimensional array.

• where and how to declare global variables

  I am creating a Flash multiple-choice quiz. I created a clip named mc_Quiz. This clip contains a layer of action and an object layer. THW action layer contains 1 keyframe with code (code of a button that moves to the next section).
  
  The object layer contains 11 contains keyframes 10 the KeyFrames
  a single movie clip question, (mc_Q1 through mc_Q10) and a btnNext to move to the next section. The video clips in question (e.g., mc_Q1) contains a "btnCheck" button and the code to check the answer.
  
  The 11th framework contains a film click that contains an input text box 'userName', a 'score' of the user's dynamic text box and a submit"" button. Not yet submit the information anywhere, I do it so that when I click on the "present" enter key 'Please enter your name' if it is empty. " And if it is not empty, it will be 'Thank you.'
  
  What I have to do is to have the 'btnCheck' to add 10 points for each correct answer to a variable. Then place this total in the 'rating' dynamictext box when the user moves the frame 10 to 11. I don't know where declaring the variable and how to add the variable every time the correct answer is given.
  
  How this is done?
  
  Here's something that does not work.
  
  First image of "mc_Quiz":
  
  Stop()
  var advanceNext:Number = currentFrame;
  static var; userScore:Number;
  btnNext.addEventListener (MouseEvent.CLICK, nextQuestion);
  
  function nextQuestion(evt:MouseEvent):void {}
  gotoAndStop(advanceNext ++);
  }
  
  
  
  As part of "mc_Q1".
  
  Stop()
  messageBox.text = ""; Clears the response area
  var correctAnswer:String = "Holy"; Good response for comparison games
  var userAnswer:String; with the value of the radio button group.
  var rbg:Object = rbA.group; Get the name of a group from the first button ragio.
  
  
  btnCheck1.addEventListener (MouseEvent.CLICK, checkAnswer1);
  
  function checkAnswer1(evt:MouseEvent):void {}
  userAnswer = String (rbg.selectedData);
  If (userAnswer == correctAnswer) {}
  messageBox.text = "Yes", + userAnswer + ' is CORRECT! ";
  userScore = score.value + 10;
  rbA.enabled = false;
  rbB.enabled = false;
  rbC.enabled = false;
  rbD.enabled = false;
  }
  else {}
  messageBox.text = "your answer is INCORRECT.";
  rbA.enabled = false;
  rbB.enabled = false;
  rbC.enabled = false;
  rbD.enabled = false;
  }
  }
  
  In fact, I have no idea where to declare the variable or how to add 10 points when I select the right answer. It seems to me that I have to some how change this variable within the function of the button.
  

  AS3 does not directly support global variables, like its predecessors, but there are ways around it. Without going through the overall road, to communicate from a child object to a parent the normal approach in AS3 object would (literally)...

  MovieClip (this.parent) .totalScore += 10;

  Alternatively, you can create a world class and use that. If you save the following in a file named "global.as" in your class path (or file that your project is the folder), you can use the variable in a global sense, while importing the class where it is needed:

  package
  {
  public const global: Object = new Object();
  }

  Use it in the Flash file...

  global import;

  global.totalScore = 0;
