• Why not use the static methods - example

  Hello world
  
  I would like to continue the below thread about "why not use static methods.
  Why not use the static methods
  with the concrete example.
  
  In my small application, I need to be able to send keystrokes. (java.awt.Robot class is used for this)
  I created the following class for these "operations" with static methods:
  

  public class KeyboardInput {
  
       private static Robot r;
       static {
            try {
                 r = new Robot();
            } catch (AWTException e) {
                 throw new RuntimeException(e + "Robot couldn't be initialized.");
            }
       }
       
       public static void wait(int millis){
            r.delay(millis);
       }
       
       public static void copy() {
            r.keyPress(KeyEvent.VK_CONTROL);
            r.keyPress(KeyEvent.VK_C);
            r.keyRelease(KeyEvent.VK_C);
            r.keyRelease(KeyEvent.VK_CONTROL);
       }
  
       public static void altTab() {
            r.keyPress(KeyEvent.VK_ALT);
            r.keyPress(KeyEvent.VK_TAB);
            r.keyRelease(KeyEvent.VK_TAB);
            r.keyRelease(KeyEvent.VK_ALT);
       }
  
                 // more methods like  paste(), tab(), shiftTab(), rightArrow()
  }

  You think it's a good solution? How could it be improved? I saw something Singleton vs somewhere of static methods. Wouldn't be better to use Singleton?
  
  Thanks for your comments in advance.

  Maheshguruswamy thanks for the tips on the steps create a singleton of this class.
  Perhaps you could say also why do you say that it would be preferable to use singleton? What is behind it? Thank you!

  In short, it seems to me that a single instance of your class will be able to coordinate actions across your entire application. If a singleton should be sufficient.

  But who doesn't answer why he expected prefer a singleton instead of a bunch of static methods. Functionally, the two are almost identical. In both cases, there is that a single 'thing' to call methods - either a single instance of the class or the class itself.

  To answer the question, the main reason to use a Singleton on a class of static methods is the same reason readers much of not static vs static decisions: polymorphism.

  If you use a Singleton (and and interface), you can do something like this:

  KeyboardInput kbi = get_some_instance_of_some_class_that_implements_KeyboardInput_somehow_maybe_from_a_factory();
  

  And then everything calling public methods of KBI has to know that there an implementor of this interface, without worrying about what concrete class is, and you can replace some implementation is appropriate in a given context. If you do not need to do, then the approach of the static method is probably enough.

  There are other reasons that may suggest a Singleton - serialization, persistence, use as a JavaBean pop to mind - but they are less frequent and less convincing in my experience.

  And finally, if this thing keeps updated a State between method calls, even if you can manage it with static member variables, it is more in line with the OO paradigm to make them non-static fields of an instance of this class.

• How the binary objects are sorted

  Live treatment image "IMAQ particle analysis" and "IMAQ MaskToROI.vi" returns the characteristics of binary objects detected in a specific order. My question is how objects are sorted before results are returned.

  Look at the following example. I'm totally confused why two screws returned the second object in the first row first?

  I was trying to get the centers of each object (and their contours) and assuming that they were sorted by their positions on the y-axis first and then positions itself on X. It is most of the time, until you see here on the first line. What happened here? Why the second object is sorted as the first object? HOW the binary objects are sorted anyway?

  

  I got it. It has to be sorted by the corner up and left of the rectangle of the object.

• How do I know that the event log are reported to any server

  Hello

  I can see all the event logs and error logs using the event viewer. But I want to know if newspapers are reported to some server just we report about a bug or non-response to application/software using the reporting window.
  I want to check if the event errors are reported on some server or not, if yes, to which server it is reported. Is this possible?
  The observer of events, or any application in the windows operating system keeps track of these reported error logs.
  Thank you

  Hello

  As mentioned by Palcouk, Event Viewer records all events and activities on your computer but does not send it to any server. The call you have received is wrong / will call that could come from a potential hacker.

  I suggest that you go through the items listed below.

  Hello

  When you are developing a Java application, that you must only have a class with a Main method, other classes do not need that method, the purpose of this methos is that it defines the beginning of your program, look at this link, it is an example and this explains also the Main method:

• Why not use the static methods

  Hello world
  
  I was informed in a previous thread to avoid using static methods it was possible.
  Why is it, could someone please tell me a little more about this? Are there best practices, concepts on this?
  
  Thanks in advance,
  lemonboston

  Hi Lemonbottom,

  The rule I used generally goes like this:

  If the method does something that I can use without the object containing it instantiate, then it can be made public static.

  In the previous examples, I had various foods. Apple might have a method called "getCaloricContent" that returns the number of calories in an Apple. I don't need an actual Apple to get this information, so I do static. However, if I want to Breathe() an Apple, then I need to build an Apple to do this, so static would not be appropriate.

  It is a loose guidance to help you get started. Try to avoid as much as possible of static methods. They add an extra dimension (often unwanted) to unit tests. It's not so say it is not a proper use of static methods.

  Once you've got your head around this concept, consider the model Singleton, who, in most cases, eliminates the need for static methods of learning.

  Kind regards

• Call the static method from Acrobat to c#

  I have a static function of C++ and I want to call this function from c# code (it's a button_click event). I tried to export this function by creating its DLL, but it does not work. My C++ function looks like this: static ACCB1 Sub ACCB2 HighlightWord(void *data). Please give some advice?

  When you say "expose plugin methods c# in a standardized manner", it means the plugin itself must be built as COM, so that its methods are exposed?

  If so why do I need to expose COM plugin together when I need to call only one method of plugin? Please specify.

  In addition, the project plugin C++ is unmanaged code. A wrapper around plugin is necessary, so that it can be exposed to c#. My understanding is correct?

• How the index data are managed within the cluster?

  Hello
  
  We are evaluating the consistency.
  
  Regarding indexes, am I right in thinking that the data in the index are stored in a (managed internally) cache on the same node that the attendant at the following indexed values? I'm not interested in getting the data in the index, but rather just to understand how the data in the index itself are stored or processed within the cluster.
  
  So in a 2 cluster node where an index is applied to a distributed cache that has only 2 entries, will there be a key cache on each node 1 {binary,} to enter key where the key points to the value that is stored on this same node? In other words, I'm sure that the index data to be spread out in the cluster in the case of a partitioned topology?

  Hi Peter,.

  up to 3.4.x index have been supported only on partitioned topology, and Yes, the index on each node contain only the data corresponding to the entries that have their main copy on this node (referred to as entered local subsequently).

  The indexes are not stored in a cache, but they are managed under the information that maintains consistency in terms of backup (the map that contains local entries).

  The indexes are in 2 parts:

  -index to the front: this is a mapping of the cache key in an internal representation (Playback key card in the future) the value extracted with the extractor used to create the index of the entry to membership of the cache key (value extracted later)

  -reverse index (aka. reversed card): this is a map of the value extracted from a backup set of the keys of the map of entries which we extract the index key reversed with the extractor used to create the index

  The index can be sorted, which means that the index reversed a SortedMap (sort order is the order of the extracted values)

  Let's see an example. Assuming you have the contents of the following cache within a particular extension storage node:

  A--> Object (PositionX = 5,...)
  B--> object (getA = 3,...)
  C--> object (getA = 3,...)
  D--> object (getA = 4,...)

  The index forward in this node will contain:

  Binary (A)--> 5
  Binary (B)--> 3
  Binary (C)--> 3
  Binary (D)--> 4

  The reverse index will contain:

  3--> {Binary (B), Binary (C)}
  4--> {Binary (D)}
  5--> {Binary (A)}

  Where Binary (...) designates the internal representation (binary) of the... object.

  If the index is not ordered, then the order of iteration over the entries in the index reversed are not deterministic.

  If the index is ordered, the iteration of the entries into the inverted index will be as stated above. Also, you can convert the SortedMap inverted index in order to have the very useful headMap and tailMap and firstKey and lastKey methods.

  I hope this helps.

• How the graph data are resampled pixels?

  A test, I created two identical graphs with land areas 500 pixels wide and a noisy sinusoidal signal of 1000 samples.  A chart displays the waveform right, while the other got the results of the use of the function Arrray to decimate to halve the number of samples.  They are not the same.

  Up to a waveform graph does exactly when it displays a data value larger than its width in pixels?

  

  As you have noticed, the graph is a little more intelligent that you expected.  When the number of points exceeds the number of pixels, a form any resampling must take place.  A simple decimation as you tried would eventually pass some interesting points.  Instead, the outliers receive priority when selecting which points to display.  Strong in this way, peaks and dips appear even on a large scale.  Reproduce this behavior yourself can be tricky.  And once you reduce the data set, the points are gone and zoom is not as effective.

  Usually, I try to let the chart to do as much as possible.  A simple and effective way to reduce the size of the data you have to ship on the network is to use the SGL precision instead of double precision.

• VPN tunnel for initiation of the static method to the dynamic side

  Hello

  In the case of site to site VPN between static IP (ASA) and dynamic IP (Linksys AG241), would it be possible to open the VPN tunnel by the static side? How can I configure it? Could you please advice?

  Thank you very much

  Nitass

  Nitass, I'm sure that you can not start session with ASA, which is on the side of the VPN server.

• Project imported from another computer, the audio files are jumping or any waveform?

  Hey everybody,

  I import a project from another version to date of first Pro CC 2014, it was working fine on another computer but on import some audio in the order and in the source monitor are jump or play just back all choppy as a bad CD. Some audio in the Control Panel Assembly have no waveform. I tried to replace some, that works, but there are a LOT of audio to replace and I'm not 100% sure those who read evil or of the previous editor.

  I visited, re-rendering, clear cache and it always does. I'm not sure what is the problem. Also sometimes when I try to make the entire project for the preview, it gives me 'cannot compile the film' unknown error.

  Any advice/help would be appreciated. Thank you!

  Pense thought to it, here's what I did in the case where someone has a similar problem - had to remove manually everything in the 'Clean' media Cache files did not really work. Am entered and removed everything for re - conform files, worked for some files, but not all. Turns out that on the other drive, there were some PEK and CFA project hidden files in this local disk. I searched .cfa files both .pek and all removed so first can regenerate new ones.  Things work now

• How the setFocus() method in AS3?

  Hello world. I'll try to keep it as simple as possible.

  I try to use the setFocus method to highlight the default text in a text input field.

  So bascially when the user clicks on the text field - the text is highlighted, and they can hit. Currently have about 16 text fields with something similar to "insert text here" as a guest for our lower ICT demographic of users and it is a bit tedious to expect the user to highlight text in each field, then tap it.

  Can be done awesomly if you tab through the fields of text, but I expect not many users use this method.

  I looked around on the net solutions to it using as3, but I have not found something that worked for me. I would be very grateful for a suggestion or a point in the right direction...

  Thank you

  If you want to by clicking on a textfield end with the text inside it, try the following...

  TF1.addEventListener (MouseEvent.MOUSE_UP, selectText);

  TF2.addEventListener (MouseEvent.MOUSE_UP, selectText);

  TF3.addEventListener (MouseEvent.MOUSE_UP, selectText);

  etc...

  function selectText(evt:MouseEvent):void {}
  evt.currentTarget.setSelection(0,evt.currentTarget.length-1);
  }

• How to select all of the people who are not in any team?

  Hello
  
  I have a nice SQL expression that gives me accordingly all the "AGENTS" (people) working in a TEAM (a team)
  
  Select one. "" AGENT_ID. "
  a."NAME" | ' ' || a.' first NAME' 'Name',
  c.libelle 'team ', he said.

  I tried but could not succeed!
  
  Thank you for your help.
  
  Christian

  Dave solutions use an outer join ((+) in the joints), which should bring back all the records of the agent, even if they do not exist in the equipe_agents table.

  Another approach would be to use a statement NOT EXISTS or NOT IN, for example

  SELECT   *
  FROM     agents a
  WHERE    NOT EXISTS (  SELECT   1
                         FROM     equipe_agents ea
                         WHERE    ea.agent_id = a.agent_id
                       )
  

• How the Add method for the control of data already created WebService

  I have total 3 methods in WSDL, and I chose one method during the creation of control data to the web service and its job very well.
  
  But now I want to add an additional method of WSDL. is it possible to add without re-creating? How to do this?

  I do not think that we support a data control WS existing in a kind of approach to the Publishing Wizard - you are without doubt better re - create the data control.
