• Access the static variable...

  Hello

  I need a static variable which holds a QMap, for this example I'll use QMap.

  I created fresh new project and I changed in applicationui.cpp:

  ...ApplicationUI::ApplicationUI(bb::cascades::Application *app) :
          QObject(app)
  {
  ....
  
      initDatabase( 1 );
      initDatabase( 2 );
      initDatabase( 3 );
      initDatabase( 4 );
  }
  
  bool ApplicationUI::initDatabase( int index )
  {
      QString database = QString( "Db%1" ).arg( index );
      QString value = QString( "data/db%1.sqlite" ).arg( index );
  
      ApplicationUI::m_databases[database] = value; // undefined reference to `ApplicationUI::m_databases'
  
      return true;
  }
  
  ApplicationUI::~ApplicationUI()
  {
      if( ApplicationUI::m_databases.count() ) // undefined reference to `ApplicationUI::m_databases'
      {
          foreach( const QString &key, ApplicationUI::m_databases.keys() ) // undefined reference to `ApplicationUI::m_databases'
          {
              QString db = ApplicationUI::m_databases[key]; // undefined reference to `ApplicationUI::m_databases'
  
              qDebug() << "Closing [" << db << "]";
          }
      }
  }
  

  and in applicationui.hpp:

  ...
  
  class ApplicationUI : public QObject
  {
      Q_OBJECT
  public:
      ApplicationUI(bb::cascades::Application *app);
      ~ApplicationUI();
  
      static QMap m_databases;
      bool initDatabase( int index );
  ...
  };
  
  #endif /* ApplicationUI_HPP_ */
  

  As you can see commented in the code above, I get error:
  no reference to 'ApplicationUI::m_databases' applicationui.cpp

  I thought to access static variables that ApplicationUI::m_databases would work.

  Can you please guide me here.

  Kind regards

  Hello! That's what I saw:

  (1) #include is present in the header file?

  ' (2) ' void ' is the syntax error:

  void MyClass::~MyClass()
  

  3)

  static QMap variable;
  

  is a declaration, you also need to create the variable in the .cpp file. Add to the .cpp:

  QMap MyClass::variable;
  

  4)

  MyClass::variable["one"] = "value One"; // doesn't work...
  

  "MyClass:" is not necessary. ['a'] variable should work too.

  UPD: this compiles (I replaced QMap QString with std::map with std::string for quick test):

  #include 

• Dreamweaver CS 5 do not support static variables PHP 5.6?

  

  I don't know what you mean by variables PHP 5.6. I just checked the online PHP manual, static variables are available since PHP 4.

  I also checked some PHP 5.6 features, such as constant expressions and functions variadique in Dreamweaver CC 2015.1. As I suspected, the built-in syntax checker does not support. To my surprise, the latest version of Dreamweaver does support the syntax PHP 5.5 . The syntax checker currently supports only PHP 5.4.

  As when Dreamweaver support the syntax PHP 5.6 or PHP 7.0, Adobe can only say. I'm not an Adobe employee, so I don't know.

• with respect to an application to turn with the help of a global static variable

  Hello. I've read a few articles on JavaFX competition, and as a beginner, so I have to practice on this subject. Now, I'm trying to implement a turn-based application which can be played between 3 to 6 players. Furthermore, I use a scene from a .fxml file and I need to update it properly depends on certain calculations of each thread (in other word players). My main problem is, I don't want to use a while loop that checks the status of similar game;

  While (GameState! = State.GAME_OVER) {}

  currentPlayer = GameBoard.getNextPlayer ();

  perform certain actions, calculations, etc.

  }

  So, I want to use threads to work instead while loop. I guess only with the help of the Service used to iterate class and assign the next player will be adapted to instead of using the while loop and the tasks for the calculation of each player, or waiting for a few responses of human players on the UI account, however, I am faced with two problems.

  1. It has a global static variable (like the GameState which is an Enumarator) determines the State of the game, so it should be updated and must be verified by each round. Is it possible to do this?
  2. How can I get rid off this while loop?

  I would like for each answer. Thanks anyway.

  It shouldn't make too much difference. The basic idea is that you have a model class that represents your state of the game (the class of game in example jsmith). When a player makes a move, you update the game state. Because this will result in changes to the user interface, this update must be performed on the Thread of the FX Application.

  If the player makes the passage is a human player, the move would be done by a user action (mouse click or press button, etc.); This will be handled on the FX Application thread in any case.

  When the State of the game changes so it is in an "artificial" player's turn to move, have the object representing the artificial player calculate his next move and then update the game state. Since it is a response to the evolution of the game state (it is the artificial player's turn), it will also be on the Thread of the FX Application.

  The only (slight) complexity comes if the calculation of displacement for the artificial player takes a long time. You don't want to perform this calculation of long duration on the Thread of the FX Application. To handle this, the cleaner is to start a task that computes the desired pass and then updates the status of the game when travel is ready. So, something like this:

  GameState game = ... ;
  // UI is bound to the game state.
  ExecutorService executorService = ... ;
  // ...
  
  final Player currentPlayer = game.getCurrentPlayer() ;
  final Task calculateMoveTask = new Task() {
       @Override
       public Move call() {
            Move move = // compute next move...
            return move ;
       }
  };
  
  calculateMoveTask.setOnSucceeded(new EventHandler() {
       @Override
       public void handle(WorkerStateEvent event) {
            gameState.makeMove(currentPlayer, calculateMoveTask.getValue());
       }
  });
  
  executorService.submit(calculateMoveTask);
  

  If you make a thread more than that, you're probably do badly... Also, there should be no need anything it either, will be held in a "global" static variable (the idea above is the only structural change you the example posted by jsmith).

• How to bind static variables?

  In ActionScript, I tried binds a variable to one static variable to another class:

  var watcher: ChangeWatcher = BindingUtils.bindProperty (Thi, "dataProvider", StaticClass, "staticVariable");

  The changewatcher fires when loading, but it fires at all during execution.  And Yes, the static variable has the [Bindable] tag next to it.  I encountered this problem a few times before, and I decided to just go around it.  However, for the sake of clean and efficient code, any help on this would be greatly appreciated.

• Definition of static Variables dynamically

  I have an application that instantiates a class several times. Many variables for the class is loaded from a XML when running and may vary each time the program runs, but will not change once the program is running.
  
  I want to initialize static variables in this category once and then rely on their values through the program. I could do this in the constructor function, but then I think that I do whenever I have to instantiate the class and so will suffer an excessive workload.
  
  1. is there a way to define static variables once and then let him go without a check in the manufacturer each time to see if they are a null value (and therefore put them)?
  
  2. do I create an instance of the class to set?
  
  Any help is appreciated.

  Just use dynamic variables. Keep all the in a class as follows:

  class myVariables
  {
  Objects: variables vars private;

  public void readVariable(name:String)
  {
  return variables [name];
  }

  public void myVariables (init:XML = null)
  {
  variables = new Object();

  default init
  variables.xxx = 5;
  variables. ABC = "test";

  If (init)
  {
  set variables for the values passed in the XML strcture;
  }
  }
  }

  MV = new myVariables();
  trace (MV.readVariable ("ABC")); Returns "test".

  You can keep the instance of this class as a global object is accessible for
  other classes without initializing it.

• Static variables in OAFramework

  Hello
  
  I'm stuck here seriously using static variables in my page. I have developed a few pages in OAFramework. I used more than 200 static variables in all pages. All is well for a single user. If more than 1 user using the page, the values are overlap between users. Now, I realized that its due to declare the values as static. How can I solve this problem?
  
  I would appreciate if someone can me advice on that.
  
  
  Jim.

  First solution to this problem is to convert all static variables to instance variables.
  However please provide details of the issue and why it is necessary to make them static.

• Static variables in the Page of the OFA

  Hello
  
  We have a requirement to show the popup message when changes are made in the page of the OFA. We use the static variable in the OPS page to store the initial values of some fields and whenever the popup needs to be shown, it compares the value of the static variable for the current value. If they are different then we are the message. It works perfectly fine when the page is accessed by the single user. But when several users access a single screen, it shows the message to a user even if the values are not changed by this user, but the other user has changed. My question is-
  
  1. do we need to use variables of session always for users multiple scenarios?
  2. How does the static variable in java? It is not unique to the session? If so, above the question shouldn't come.
  3. how to solve the problem above?
  
  Pointers on this would be a great help.
  
  Thank you
  Shree

  I did not understand the part same page can be accessed by different users. In any OA framework Page, the same page is accessible by several users. If you think abt the same data updated at the same time, then search functionality of Version number of the object in the context of OSTEOARTHRITIS.

  All instances of the VO are unique for each session. So no need to worry about this side here.

• What is the best way to copy a static variable of C in LabVIEW?

  As an interesting project / fun, I'm trying to implement the bcrypt algorithm in some native G, without using libraries (for example, no link DLL, all of the native code G). Everything is going well so far, with the exception of a minor roadblock I ran into. The bcrypt algorithm involves initialization of a state variable with a range of 4 x 256 of hex codes derived the decimals of pi. In C code, it looks like:

  unsigned int BF_init_state = {}
  
  	{
  
  		{
  
  			Initial state of the line 1s
  
  		}, {
  
  			Initial state of the line 2 S
  
  		}, {
  
  			Initial state of the 3 S-line
  
  		}, {
  
  			Initial state of the line 4S
  
  		}
  
  	}, {
  
  		State initial P goes here
  
  	}
  
  };

  I know that this should be in favour of some sort of import JSON, or perhaps directly via the menu data operations, but I'm not 100% sure on the best way to do it. Any ideas?

  I truncated lines, so if you are interested in getting the complete code, see crypt_blowfish.c on GitHub.

  This will make only a row/column at a time, but I think that's what you're looking for.

  

• How to deploy shared to the PC remotely variables programmatically

  Hello

  I am facing a problem of programmatic deployment of SVs generated to a PC remotely (not a real-time target). Now, I have tried two approaches:

  1."add the variable to library.vi' and that the"Library Library.Deploy"method where I pointed the remote IP (I tried multiple address formats). If I have the target value IPAddress localhost or I type in local IP variables are deployed successfully.

  2. with the help of DSC: "Create shared variable.vi" and then defining SharedVariableIO Network.URL property at different addresses. However, it did not work either. In general I like this approach more because it deploys no doubt without creation of a library.

  Is there a way to do this? I looked everywhere on the internet and there aren't any examples how to do on the network.

  Another problem is I can not set the initial value of a table previously deployed with one of above approaches. But I found this option (below) on the site of NOR, so I guess I must first deploy, then connection open Variable, write variable,...?

  

  Thank you for the help

  Planko dear,

  You can also do is to create some kind of service on the server, which would be able to create the SVs locally, after receipt of applications by others, already deployed shared variable or same TCP message.

• ICB cannot link static lib VS2010 files

  A whole new file static lib created in VS2010 Express hat the following content:

  StaticLib.h:

  call __stdcall void (void);

  StaticLib.c

  __stdcall Sub call (void) {}

  VS2010 compiles this as a c file. It is already ensured by the end '.c', but to be sure, I use the compiler option/TC.

  All other options to their default values. I compile using "Release | Win32. "

  The created lib file is copied into a new CVI folder, as well as the header.

  Two files are added to the project.

  In addition, a main.c is created with the following content:

  void main (void) {call() ;}

  The compilation attempt is abandoned with the following error message:

  Incorrect header encountered during playback of external module: 'Release\StaticLib.obj '.

  Aborted charge of Member "Release\StaticLib.obj" of the library 'c:\C90\LibImportTest\Release\LibImportTest.lib '.

  Is it possible to reuse the static lib files compiled in VS2010 with CVI?

  If Yes, please show me a minimal example.

  (please do not post suggestions about the dll)

  I tried with CVI 2012. I think it's the setting of the project 2010 VC: Configuration Properties > General > Whole Program Optimization use link Time Code Generation that is causing the problem with CVI. Change this setting to 'No Whole Program Optimization' and CVI 2012 is able to bind the file lib VC 2010 for me. Hope it's the same problem for you. Otherwise, try to change the other VC optimization or the language settings in the project properties dialog box.

• Problem with URL links with variable creation

  Hello

  I am trying to create a zoom ratio. This is the link that I got for my report in detail, I took it from the LINK of REPORT of SHARE and I chose the CURRENT PAGE:

  BiDev:9704/Analytics/Saw.dll?bipublisherEntry & Action = open & itemType = .xdo & bipPath=%2FTEST%2F00-TEST_REPORT.xdo & bipParams = {'_xmode': '2'}

  I have a variable binding in my DATA MODEL called P_CREATED.

  How to pass the value so that when the report is open, this variable will be used.

  I found this on a blog: http://bipconsulting.blogspot.ca/2010/02/drill-down-to-detail-or-another-report.html

  But somehow, his link is quite different from mine.

  Thank you

  I found the problem and it was pretty simple, I was going to BI Publisher via OBIEE (bidev:9704 / Analytics).

  Instead, go directly to the BI PUublisher (bidev:9704 / xlmpserver).

• How can I generate a new file/link static?

  Im trying to figure out how to approach a problem. what I want to do is to generate a new file/link, perhaps using "cffile" or any other way.

  Right now I have cse_newsletter.cfm, which looks like this (type of)

  <html>
  .......
  <cfquery>
  select ....
  </cfquery>
  select ....
  <cfquery>
  </cfquery>
  .......
   <cfoutput>
        <h1>Starburst Star Award</h1>
       <h3>Winner: Department- #highest_dept_name_average#</h3>
       <h3>Average:  #hihest_dept_average# </h3>
       <h4>Runner-up: Department- #highest_dept_name_runnerup# </h4>
       <h4> Average: #highest_dept_name_average_runnerup# </h4>
    </cfoutput>
  </html>
  
  

  the query works and give me I want a correct output. (rigth now I use cfshedule to execute it, but every time I run it will overwrite the old data with the new) what he does, he gives me the data of the past month.

  so every tiime it works should give me the data from last month.

  I would like to do that whenever I click on transmission (maybe there is a better way to do it without submit) it will give me a static link/txt that contains the data.

  I know that with cffile = "Write" he can give me a txt file (and this file can be replaced), but I would preffer so is easier for me a link on cse_newsletter.cfm which will output/display which is on the body now to the cse_newsletter.

  Please give me any tips/suggestions, maybe an article I read online (have not found something that can help me)

  This right is the cfshedule, right now is on the update, so sure it won't work with the update, but I don't think that with what I want, I can accomplish with cffile 'writing '.

  <cfschedule action = "update"
      task = "TaskName" 
      operation = "HTTPRequest"
      url = "cse_execoffice_newsletter.cfm"
      startDate = "04/18/14"
      startTime = "11:19 AM"
      interval = "3600"
      resolveURL = "Yes"
   >
  

  Thank you

  I mean your cse_newsletter.cfm model can be designed to accept parameters to view a newsletter of a certain month and year. If it accepts URL parameters, then you can create a link to it like this:

  http://mydomain.com/cse_newsletter.cfm?month=1&year=2014

  And if the parameters are not passed, you could do that show the user a list of months and years (control for example via the selection list form) so that they can select the month and year they need. That's how he could design in any case. Unless your data is stored somewhere in a database, your model would never work for a scenario (last month), and it's a great limitation because no one can observe beyond newsletters. You may not write files to disc etc, because the model has just need to show correct information letter. You can create any link to the newsletter you need once it has been designed to accept parameters month and year (which are in turn to your CFQUERY tags to get the data).

• How can I set a static variable with another variable?

  Is it possible to do this? I want to have a Static String variable that has a part of the dynamic string based on another variable. I know that probably sounds ridiculous, then, if so, give a suggestion concerning best practices in what I'm trying to do.
  
  Thank you.

  He is the dumbest question ever. Just ignore me.
