• Possible to add an existing class as a child of another class?

  Hello

  I need to test a code for features (a PMBus on I2C features on a Board of sup - 20). Ultimately it is a subclass of instrumentation in the higher program, but I did not yet a large part of the overall program. Is it possible to create first class pilot Sub-20 and later attach it in class instrumentation of the program?

  Thank you

  Simon

  Theoretically, Yes, but if the parent class has data items, you obviously won't be able to use them during your development. In addition, any screws that you create in the parent class that are dynamic distribution must be already implemented in the class of the child.

  In other words, you have little to already know what needs to be like the parent class. Why not go ahead and create it? At least a draft, with all data and the screws using the classes your child?

• Not allowed for hyphens class names (was: naming conventions, the names, Dreamweaver CC class)

  I just downloaded and started working with Dreamweaver CC. On inserting a div tag, I found that the program won't let me not use hyphens in the names of class. Why not? AFAIK there is no protocol that says that you can not use hyphens. I worked with a jquery plugin that uses hyphens widely. What am I supposed to do? Change all the class names in the css and script that comes with it is not the right way to go - as much as I have tried and it doesn't work...

  Hi LarkinAngel,

• import a class: how many ways are there? CFC, import, extend the base class

  How many ways is there to import a class and am I confused

  1 screen/public class extends MovieClip

  This inherits all the properties and methods of the MovieClip class so WHY again do we use: import flash.display.MovieClip;

  Import something else or just made the job twice

  2 import flash.display.MovieClip - so no need to extend (repeat me once again - see 1)

  3 CFCS: connect to a CFC

  4. stir in a SWF with a meta tag

  5. in the properties panel menu - add a class as a base class

  OMG - a bit confusing

  You can only "extend" another class if the compiler knows where he is.

  The import statement is only by the compiler to find the class on your hard drive.

  It is not "import" of the entire class in the sense that you import a BMP in Photoshop.

• Class.forName in jdbc

  Hello
  
  I know that this has been discussed a few times before but I'm still not clear on this.
  
  Why do we Class.forName while the implementation of jdbc.
  
  In which case it is for the class loading, why have we not need for another class. How reactivates JVM knows how to find the class and load it when we pray for the other classes.
  
  (I understand that calling Class.forName calls the static method in this document, which records the pilot as a driver available in the DriverManager class, but my question is why do we need to load jdbc class and not for others).
  
  Any response will be a great help.

  Using Class.forName (or the service-loader) allows the use of drivers that did not exist when the program was written

  If they existed or not, the point key here (and I completely missed during the validation of my answer) is that you can see what driver use prior to execution, which means that your application can be run against DBs from different vendors without any code changes.

• Pass the URLLoader() variable between classes

  I have two classes. See below.

  What I want to do is quite simple, but I do not know how to do. I want the URLFactory for create table and store it in the variable 'dataArray' and use the table in the main class, by calling the GetList() class URLFactory. I have returns nothing... Please help

  Basically, I need to set a variable equal to URLLoader.data (var something: String = URLLoader.data) so I can use this variable in other classes. WHY ISN'T IT EASIER? Please, I beg you. A solution would be much appreciated.

  package classFiles
  {
  import flash.display.MovieClip;
  Import classFiles.URLFactory;
  
  SerializableAttribute public class MainClass extends MovieClip {}
  private var _UrlDriver:URLFactory;
  
  public void MainClass() {}
  _UrlDriver = new URLFactory ('url');
  var temp: Array = _UrlDriver.GetList ();
  
  }
  
  }
  
  }

  package classFiles
  {
  import flash.net.URLRequest;
  import flash.net.URLLoader;
  import flash.display.MovieClip;
  import flash.events.Event;
  import flash.sampler.Sample;
  
  SerializableAttribute public class extends MovieClip {} URLFactory
  
  private var loader: URLLoader;
  public var textData:String;
  public var dataArray:Array;
  
  public void URLFactory(url:String) {}
  textData = "";
  this.dataArray = new Array();
  loader = new URLLoader();
  loader.addEventListener (Event.COMPLETE, HandleComplete);
  Loader.Load (new URLRequest (url));
  
  Temp = CreateDataArray();
  }
  
  function HandleComplete(e:Event):void {}
  
  textData = loader.data;
  
  trace (dataArray);
  
  }
  
  function CreateDataArray (): void {}
  
  trace (dataArray);
  dataArray = textData.split ("\n");
  dataArray = textData.split('","');
  }
  
  public void GetList (): Array {}
  
  return dataArray.
  
  }
  }
  
  }

  Yes, the data loading is not instantaneous.  This is why you use a complete listener in your factory.

  Similarly, you must use a listener in your main class to check if the data is ready.

  p.s. Please check the useful/correct.

• problem between objects of class

  well, I'm a huge refactoring ActionScript file and so tried to move some functions in their own classes.  Why does this work?  I have a function in my primary class:

  // ...

  
  

  private var testBlock:Sprite;

  
  

  public Function testingINT() {}

  testBlock = new Sprite();

  var TB = new TAPATTesting();

  testBlock = TB.makeTestBlock ();

  TAPATContainer.addChild (testBlock);

  }

  ... testingINT() is called away

  and then, the class TAPATTesting is here:

  package com.bpi.tapat

  {

  import flash.display. *;

  import flash.text.TextField;

  import flash.text.TextFieldAutoSize;

  import flash.text.TextFormat;

  public class TAPATTesting { }

            

  public var testBlock:Sprite;

  public var test1TXT:TextField;

  public var test2TXT:TextField;

  public var test3TXT:TextField;

  public var test4TXT:TextField;

  public var test5TXT:TextField;

  public var test6TXT:TextField;

  public var test7TXT:TextField;

            

  public function TAPATTesting ():void {}

                 

            }

            

  public function makeTestBlock (): Sprite {}

                 

  var formatTest: TextFormat = new TextFormat();

  formatTest.font = "Monaco";

  formatTest.color = 0xCCCCCC;

  formatTest.size = 10;

                 

  testBlock = new Sprite();

                 //

                 var textX = 50;

                 var textY = 270;

  test1TXT = new TextField();

  test1TXT.autoSize = TextFieldAutoSize.LEFT;

  test1TXT.defaultTextFormat = formatTest;

  test1TXT.x = textX;

  test1TXT.y = textY;

  testBlock.addChild (test1TXT);

                 //

  test2TXT = new TextField();

  test2TXT.autoSize = TextFieldAutoSize.LEFT;

  test2TXT.defaultTextFormat = formatTest;

  test2TXT.x = textX;

  test2TXT.y = textY + 20;

  testBlock.addChild (test2TXT);

                 //

  test3TXT = new TextField();

  test3TXT.autoSize = TextFieldAutoSize.LEFT;

  test3TXT.defaultTextFormat = formatTest;

  test3TXT.x = textX;

  test3TXT.y = textY + 40.

  testBlock.addChild (test3TXT);

                 //

  test4TXT = new TextField();

  test4TXT.autoSize = TextFieldAutoSize.LEFT;

  test4TXT.defaultTextFormat = formatTest;

  test4TXT.x = textX

  test4TXT.y = textY + 60;

  testBlock.addChild (test4TXT);

                 //

  test5TXT = new TextField();

  test5TXT.autoSize = TextFieldAutoSize.LEFT;

  test5TXT.defaultTextFormat = formatTest;

  test5TXT.x = textX;

  test5TXT.y = textY + 90;

  testBlock.addChild (test5TXT);

                 //

  test6TXT = new TextField();

  test6TXT.autoSize = TextFieldAutoSize.LEFT;

  test6TXT.defaultTextFormat = formatTest;

  test6TXT.x = textX;

  test6TXT.y = textY + 110;

  testBlock.addChild (test6TXT);

                 //

  test7TXT = new TextField();

  test7TXT.autoSize = TextFieldAutoSize.LEFT;

  test7TXT.defaultTextFormat = formatTest;

  test7TXT.x = textX;

  test7TXT.y = textY + 140;

  testBlock.addChild (test7TXT);

                 

                 return testBlock;

            }

       }

  }

  So, therefore, I would that testBlock in the primary class would have the Sprite testBlock of the TAPATTesting passed to him.  The problem arises here in another function of the primary class:

  private Function testReport() {}

                      

  testBlock.test1TXT.text = ' # effect: " + currentStim + ' / ' + numberStims;"»

  testBlock.test2TXT.text = ' stem length: " + stimDuration;"»

  testBlock.test3TXT.text = ' inter-stim int: " + interStimInterval;"»

  testBlock.test4TXT.text = "target freq:" + targetFrequency; "»

       //

  testBlock.test5TXT.text = ' stem angle: " + stimAngle;"»

  testBlock.test6TXT.text = ' stim dist: ' + stimDistance;

       //

  testBlock.test7TXT.text = ' user evaluation: " + userResponseTime + "ms";". "

  }

  I get this same error on each of these lines:

  Several markers to this line:

  -1119: access to property may be undefined test7TXT through a reference with static type flash.display:Sprite.

  Why can't I access the Sprite testBlock children?

  That's because TestBlock is a Sprite, and a Sprite is not a property named "test7TXT".

  You can still access them by doing something like the following:

  -Give the textfield object a name

  test7TXT = new TextField();

  test7TXT.name = "test7TXT";

  test7TXT.AutoSize = TextFieldAutoSize.LEFT;

  test7TXT.defaultTextFormat = formatTest;

  test7TXT.x = textX;

  test7TXT.y = textY + 140;

  testBlock.addChild (test7TXT);

  -Access to the textfield object using its name

  TextField (TestBlock.getChildByName ('test7TXT')) .text = "assessment of users...". » ;

  Note that getChildByName returns the object as a DisplayObject, you will need to cast to a TextField.

  I hope this helps.

• PB with the path to the actionscript 3.0 classes

  Hello
  
  I get an error that drives me crazy.
  I recently had to reinstall Flash CS3.
  I created an AS 3.0 using MovieClip class, it's included by importing as usual:
  import flash.display.MovieClip;
  
  I get error message 1014 says that intrinsic classes are no longer taken into charge (& quot; The intrinsic attribute is no longer supported & quot ;) by referring to a native class, MovieClip.as, that uses the intrinsic attribute to define the class.
  
  Why do I all of a sudden this error I get never before?
  It seems that if I use old native classes...
  
  Thank you

  PS: I checked my class path: C:\Program Files\Adobe\Adobe Flash CS3\fr\First Run\Classes\FP9
  
  It seems ok...

  I restarted flash and it works now :)

• LVOOP - Casting Weirdness

  I discovered a strange behavior of the method "to more specific class '... I use LV2011SP1.

  My request:

  I have an application that analyzes a collection of blobs of data, with each blob of data defined by a class of LV. Each of these blobs of data inherit from a common parent. I store my collection of BLOB data in a table. Standard stuff.

  Obviously each blob data must be upcast to the parent type when stored in a table, but the execution of each element of the array value is kept as a type of child correct data.

  It is part of the analysis where I have to do some type of control for some of the blobs, so I use the primitive "to more specific class" in an attempt to cast the elements of my table to the desired data type. A mismatch between the input type and the target type should produce an error, right?

  Here's the weird part:

  • If I use the method "to more specific class ' to directly mount a class of the child to a different type, the cast fails (as expected).
  
  
  • When I use the method "to more specific class" to one of my elements of array cast to a different type, the cast * always * succeeds. Why?

  The image below illustrates the problem. Ferrari and Mini are the two children in the car. Mini cast Ferrari gives an error (as expected), but casting an upcasted Ferrari version Mini works! This seems strange to me since the execution of the target type value is 'Ferrari' (as illustrated by the probe).

  Then why the method "to more specific class ' use values of execution of its entries?

  

  Just a quick follow-up...

  I found all my answers in this post over at LAVA: http://lavag.org/topic/16081-am-i-understanding-the-reason-why-i-have-to-use-preserve-rt-class-corre...

  It seems that the function of "preserve the Runtime class" does exactly what I need, i.e., it performs its type checking based on the value of execution of the reference to entry class. On the other hand, the function "to the more class specific" is very similar but not the verification at the time of publishingof its type.

  The information is useful, but not so clear from the help page!

• 6501 units are not interchangeable?

  I have a program that uses the dll nicalu to moitor entries on a NOR-DAQ 6501 States.  It seems that if I install the NOR-DAQ drivers with a particular switch attached, the dll never recognizes another unit of 6501.  I have uninstalled/reinstalled the NOR-DAQ drivers and the only 6501 device that works is the one that is connected to the origin.

  I wiped another PC and loaded the drivers with another unit of 6501 and this 6501 unit works, but again, no 6501 unit only works with this computer.

  6501 units are somehow related to the hardware configuration?

  The main objective of this exercise is to the image of a hard drive with the NOR-DAQ drivers loaded to install on each PC using a 6501.  Right now the image restored PC only work with the 6501 that was used on the original PC and they have their own NO-DAQ 6501 units which do not work unless the player is cleared and the operating system is recharged, then installs it to NOR-DAQ drivers.

  Although 6501 are linked to a PC, I do not understand why uninstall and then reinstall the software OR-DAQ and the drivers do not work contrary to wipe the hard drive and then installing the NOR-DAQ software and drivers?

  Hi Dustin_IDI,

  NOR-DAQmx devices have names which are assigned to the first time they are connected on the PC, such as 'Dev1' and 'PXI1Slot5 '. For devices USB, these names are associated with the serial number of the device, so NEITHER-DAQmx will see the second USB-6501 as "Dev2', the third as"Dev3", etc..

  If you uninstall / reinstall OR DAQmx, the database maps between names and serial numbers is preserved, which explains why you get different results when you uninstall / reinstall OR-DAQmx, compared to when you wipe the hard drive and reinstall everything.

  If you open Explorer Measurement & Automation, you can use it to remove the old device and rename the new device to have the name of your application expects. Another approach is to modify your application to find the names of the installed devices, as described in How I can get all devices on my Machine DAQmx name programmatically?

• Photosmart 5520 (but also others) duplex printing cleared at the bottom

  Very recently, I bought a Hp Photosmart 5520 and I found that sometimes the bottom of a page is cut off when printing double-sided. I looked in this forum and found that this problem is hardware related and can not be solved, but there are solutions. I did a few tests with my current setup and I want to share my discoveries, here for other users waiting for HP to add a FAQ for the photosmart 5520 entry. (but also for the 6520 and 7520, probably)

  The problem is clearly stated in a few messages, dating from September 2013 and Nov 2013, although it is not very easy to find

  http://h30434.www3.HP.com/T5/other-printing-questions/duplexing-discrepancy/m-p/2470573/highlight/tr...

  http://h30434.www3.HP.com/T5/scanning-faxing-and-copying/double-sided-printing-is-cut-off-short-Phot...

  Basically, the margin of the low printable area is 3mm side simple impression, while it is 15mm (at least!) for the first page, double-sided printing. This is due to the fact that the printer must keep the paper in the output roll after that that he finished printing the first page. It is therefore IMPOSSIBLE to duplex - print a document with text or graphics that extends beyond the margin of the lower 15 mm, unless the page size is reduced so that the effective bottom margin is 15 mm. On the other hand, if the document does not contain text or graphics beyond bottom margin of 15 mm it CAN be printed double-sided without reduction.

  IMHO, the problem is that the default behavior of the firmware of the printer, the drivers of operating system and/or applications do not always properly address this limitation leading to surprising or unsatisfactory results.

  To better understand the limits and behavior of the printer, I have carried out tests under the following conditions:

  (1) copy 2-sided vs 1-side in the printer display

  (2) Windows 7 applications: Word2010, Foxit PDF reader, Acrobat PDF reader

  (3) 4.3 android: Cloud Print and HP ePrint apps

  The firmware in the printer is MGP5CN1351AR (Sep 12, 2013)

  The windows version of printer drivers is 28.8 (October 30, 2012)

  For tests 2 and 3, I have prepared a document word of 2 pages with headers and footers located exactly at 15 mm of margin top and bottom of the page and I have produced a PDF with CutePDF (unfortunately this forum does not allow attachments, otherwise I would have attached it).

  The results were as follows

  (1) in 2-sided copy the last 15 mm on part and on the other copy of the output are empty, even if the text of the content entry page, while, in 1-sided copy only the last 3 mm are empty (resizing is turned off, of course)

  (2) double-sided printed of Word2010 gives a duplexer not resized when the printing preferences, advanced options, "Arrangement" is disabled. If it is set on, the output is reduced. Print PDF files is tricky: there are several different options in Foxit PDF and acrobat PDF. Auto-Centre and adjustment - on the page to print double-sided, but do not keep the right size in Foxit PDF reader; If preserve layout is off a significant part of the bottom of the page is not printed, apparently due to the fact that the margins are not properly managed by foxit PDF. Acrobat PDF instead, leave a good impression both sides preserve the page layout and scaling are disabled (obviously up to 15 mm).

  (3) android Cloud Print prints the word and pdf files WITHOUT a provision to 'preserve', this is why some clipping may occur; HP ePrint prints two word files and pdf reduced in size, as if "preserve layout" option has been set.

  In summary, I'll leave the "preserve layout" options always on in windows and I'll take a cut on the side of double-sided printing and I use hp eprint instead of cloudprint. If the correct size is important to a PDF file, it is best to experiment with Acrobat PDF (even if it is not a light program). iI would be expected at HP improved the behavior of the windows printer drivers to print a PDF file.

  I hope that this post may be useful to other people.

  You are right, that the effective page size is reduced because of the extra margins required to manage the document in automatic duplex mode.  From the rear is donated in the printer from the bottom and bottom printed in the top margin is also higher top for the back to the front.

  The checkbox 'Keep the page layout' is important for results appropriate, although it will reduce the effective print size.

  I've seen reports before of Foxit PDF printing problems, I avoid and use Adobe Reader.

• How to get a TimerTask program itself?

  I'm trying to run a TimerTask to repeat at irregular intervals.

  that is when the TimerTask is running, it calculates the next interval, cancels, then attaches to the new interval.

  Like this:

  _runTimer = new TimerTask() {
      public void run() {
          _runTimer.cancel();
          int next = program[step];
          timer.schedule(_runTimer, next);
          step++;
      }
  };_runTimer.run()
  

  Except that it explodes with IllegalStateException on the row of the table.

  So if a TimerTask cannot plan itself, is there another model of how to do?

  Thank you

  If you want your TimerTask to run at irregular intervals, you can create a custom class that extends and create instances of it to the list.

  Timer timer = new Timer();
  
  private class RunTimer extends TimerTask {
     public void run() {
        int next = program[step];
        timer.schedule(new RunTimer(), next);
        step++;
     }
  }
  
  _runTimer = new RunTimer();
  
  timer.schedule( _runTimer(), program[step] );
  step++;
  

• Question about UiApplication.getUiapplicatin ().

  Hi all,.

  Hope everything goes well. In fact, I want to ask UiApplication.getUiApplication () gives you your application instance (please, correct me if I'm wrong). Let's look at the code

  public class SimpleSmsChatApp extends UiApplication  {
  
      // Constructor
      public SimpleSmsChatApp() {   
  
          //Create the main screen and push it on to the display stack
          SimpleSmsChatMainScreen mainScreen = new SimpleSmsChatMainScreen(chatScreen,  createProfileScreen);
          pushScreen(mainScreen);  
  
      } //end of constructor
  
      public static void main(String[] args) {
  
          //Create an instance of the application
          SimpleSmsChatApp app = new SimpleSmsChatApp();
  
          // Start the event displatch thread
          app.enterEventDispatcher();
  
      } // end of main()
  
  } //end of class SimpleSmsChatApp
  

  It is a main class simple code. Now suppose I have add a method in this class as follows

  public class SimpleSmsChatApp extends UiApplication  {
  
      private CreateProfileScreen createProfileScreen;
      private ChatScreen chatScreen;
  
      // Constructor
      public SimpleSmsChatApp() {   
  
          //Create the main screen and push it on to the display stack
          SimpleSmsChatMainScreen mainScreen = new SimpleSmsChatMainScreen(chatScreen, createProfileScreen);
          pushScreen(mainScreen);  
  
      } //end of constructor
  
          public static void main(String[] args) {
  
          //Create an instance of the application
          SimpleSmsChatApp app = new SimpleSmsChatApp();
  
          // Start the event displatch thread
          app.enterEventDispatcher();
  
      } // end of main()
  
      public ChatScreen getChatScreen() {
  
          if (chatScreen == null) {
  
              chatScreen = new ChatScreen();
  
          }
  
          return chatScreen;
  
      } //end of getChatScreen()
  
        public CreateProfileScreen getCreateProfileScreen() {
  
          if (createProfileScreen == null) {
  
              createProfileScreen = new CreateProfileScreen();
  
          }
  
          return createProfileScreen;
  
      } //end of getChatScreen()
  
  } //end of class SimpleSmsChatApp
  

  Now I have another class in which I have pimples. Suppose that on the button clicks I want to createProfileScreen and window shows. I have code like this

   if (field == searchButton) {
  
       CreateProfileScreen createProfileScreen = UiApplication.getUiApplication().getCreateProfileScreen();                                                                                             UiApplication.getUiApplication().pushScreen(createProfileScreen);
  
   }
  
   if (field == chatButton) {
  
       ChatScreen chatScreen = UiApplication.getUiApplication().getChatScreen(); 
  
       UiApplication.getUiApplication().pushScreen(chatScreen);
  
   }
  

  My question is that

  UiApplication.getUiApplication()
  

  gives you the instance of the same instance I created in my main class i.e. SimpleSmsChatApp. But it gives me the error that cannot find symbol getChatScreen().

  I want to ask that whe

  UiApplication.getUiApplication(
  

  give me the instance of the main class (SimpleSmsChatApp) and I have getChatScreen() and getCreateProfileScreen() in my main class so why it gives me error that cannot find symbol.

  I'm doing this because I want any number of screens I have in my project, I created each instance of the form only once and then call the instance whenever I need fron any class.

  Please clear my confusion about UiApplication.getUiApplication (). No matter what I'm doing wrong and how achieve what I'm trying doesn't mean created instance only once and call it whenever I need any class

  Thank you

  UiApplication.getUiApplication retrieves the current instance of UiApplication.

  Please modify your code to convert, and then call the function like this:

  ((SimpleSmsChatApp)UiApplication.getUiApplication()).getChatScreen();
