  • XNA and Ninject: Syntax for dependency arguments?

    - by Rosarch
    I have a class with a public constructor: public MasterEngine(IInputReader inputReader) { this.inputReader = inputReader; graphicsDeviceManager = new GraphicsDeviceManager(this); Components.Add(new GamerServicesComponent(this)); } How can I inject dependencies like graphicsDeviceManager and new GamerServicesComponent while still supplying the argument this?

  • Using an interface as a constructor parameter in Java?

    - by aperson
    How would I be able to accomplish the following: public class testClass implements Interface { public testClass(Interface[] args) { } } So that I could declare Interface testObject = new testClass(new class1(4), new class2(5)); Where class1 and class2 are also classes that implement Interface. Also, once I accomplish this, how would I be able to refer to each individual parameter taken in to be used in testClass? Thanks :)

  • Do you use logical negation operator (!) in "if" statement or check on "== false"

    - by Taras Terebkov
    Hello everyone, I just want to conduct a little survey about code style developers prefer. For me there are two ways to write "if" in such languages as Java, C#, C++, etc. (1) Logical negation operator public void foo() { if (!SessionManager.getInstance().hasActiveSession()) { . . . . . } } (2) Check on "false" public void foo() { if (SessionManager.getInstance().hasActiveSession() == false) { . . . . . } } I always believe that first way is much worst then the second one. Cause usually you don't "read" the code, but "recognize" it in one brief look. And exclamation symbol slipped from your mind, just disturbing you somewhere on the bottom of your unconscious. And only during reading the "if" block below you understand, that the logic is opposite - no sessions in "if" On the other hand in the second way of writing, an eye immediately catches words "SessionManager", "hasActiveSession" and "false". Also for me, the situation with "true" is different. In code like class SessionManager { private bool hasSession; public void foo() { if (hasSession == true) { . . . . . } else { . . . . . } } } I find "true" superfluous. why we repeating the sentence two times? The following is shorter and quicker to catch. class SessionManager { private bool hasSession; public void foo() { if (hasSession) { . . . . . } else { . . . . . } } } What do YOU think, guys?

  • How to access the map returned by IParameterValues::getParameterValues()?

    - by Hua
    I declared a command and a commandParameter for this command. I specified the "values" of this commandParameter as a class implemented by myself. The implementation of this class is below, public class ParameterValues implements IParameterValues { @Override public Map<String, Double> getParameterValues() { // TODO Auto-generated method stub Map<String, Double> values = new HashMap<String, Double>(2); values.put("testParam", 1.1239); values.put("AnotherTest", 4.1239); return values; } } The implementation of the handler of this command is blow, public class testHandler extends AbstractHandler implements IHandler { private static String PARAMETER_ID = "my.parameter1"; @Override public Object execute(ExecutionEvent event) throws ExecutionException { String value = event.getParameter(PARAMETER_ID); MessageDialog.openInformation(HandlerUtil.getActiveShell(event), "Test", "Parameter ID: " + PARAMETER_ID + "\nValue: " + value); return null; } } Now, I contribute the command to a menu, <menuContribution locationURI="menu:org.eclipse.ui.main.menu"> <menu id="my.edit" label="Edit"> <command commandId="myCommand.test" label="Test1"> <parameter name="my.parameter1" value="testParam"> </parameter> </command> Since I specified a "values" class for the commandParater, I expect when the menu is clicked, this code line "String value = event.getParameter(PARAMETER_ID);" in the handler class returns 1.1239 instead of "testParam". But, I still see that code line returns "testParam". What's the problem? How could I access the map returned by getParameterValues()? By the way, following menu declaration still works even I don't define "ppp" in the map. <menuContribution locationURI="menu:org.eclipse.ui.main.menu"> <menu id="my.edit" label="Edit"> <command commandId="myCommand.test" label="Test1"> <parameter name="my.parameter1" value="ppp"> </parameter> </command> Thanks!

  • Designing WCF interface: no out or ref parameters

    - by Captain Comic
    I have a WCF service and web client. Web service implements one method SubmitOrders. This method takes a collection of orders. The problem is that service must return an array of results for each order - true or false. Marking WCF paramters as out or ref makes no sense. What would you recommend? [ServiceContact] public bool SubmitOrders(OrdersInfo) [DataContract] public class OrdersInfo { Order[] Orders; }

    I'm trying to create a custom property for my web part, but can't get it to show up in Sharepoint.

  • Paperclip not running tasks but not showing errors

    This is strange. I just did a deploy to a cluster server, and since then, pictures have not been processing. Reading the logs, I usually do not get an error at all, but they never finish.

  • Swing: How do I run a job from AWT thread, but after a window was layed out?

    - by java.is.for.desktop
    My complete GUI runs inside the AWT thread, because I start the main window using SwingUtilities.invokeAndWait(...). Now I have a JDialog which has just to display a JLabel, which indicates that a certain job is in progress, and close that dialog after the job was finished. The problem is: the label is not displayed. That job seems to be started before JDialog was fully layed-out. When I just let the dialog open without waiting for a job and closing, the label is displayed. The last thing the dialog does in its ctor is setVisible(true). Things such as revalidate(), repaint(), ... don't help either. Even when I start a thread for the monitored job, and wait for it using someThread.join() it doesn't help, because the current thread (which is the AWT thread) is blocked by join, I guess. Replacing JDialog with JFrame doesn't help either. So, is the concept wrong in general? Or can I manage it to do certain job after it is ensured that a JDialog (or JFrame) is fully layed-out? Simplified algorithm of what I'm trying to achieve: Create a subclass of JDialog Ensure that it and its contents are fully layed-out Start a process and wait for it to finish (threaded or not, doesn't matter) Close the dialog I managed to write a reproducible test case: EDIT Problem from an answer is now addressed: This use case does display the label, but it fails to close after the "simulated process", because of dialog's modality. import java.awt.*; import javax.swing.*; public class _DialogTest2 { public static void main(String[] args) throws Exception { SwingUtilities.invokeAndWait(new Runnable() { final JLabel jLabel = new JLabel("Please wait..."); @Override public void run() { JFrame myFrame = new JFrame("Main frame"); myFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); myFrame.setSize(750, 500); myFrame.setLocationRelativeTo(null); myFrame.setVisible(true); JDialog d = new JDialog(myFrame, "I'm waiting"); d.setModalityType(Dialog.ModalityType.APPLICATION_MODAL); d.add(jLabel); d.setSize(300, 200); d.setLocationRelativeTo(null); d.setVisible(true); SwingUtilities.invokeLater(new Runnable() { @Override public void run() { try { Thread.sleep(3000); // simulate process jLabel.setText("Done"); } catch (InterruptedException ex) { } } }); d.setVisible(false); d.dispose(); myFrame.setVisible(false); myFrame.dispose(); } }); } }

  • Android - doInBackground() error in AsyncTask

    - by AimanB
    What my app here basically does is it captures a photo or import from gallery, and when the Upload button is pressed, the image will be uploaded to a localhost server. Before I implemented AsyncTask into the process, it doesn't have any problem uploading whatsoever. Now that I've put AsyncTask, everything went wrong. I don't know which part that I do wrong in this phase. This is what logcat shows when I try to upload an image file: 10-28 17:23:25.989: E/AndroidRuntime(3356): FATAL EXCEPTION: AsyncTask #5 10-28 17:23:25.989: E/AndroidRuntime(3356): java.lang.RuntimeException: An error occured while executing doInBackground() 10-28 17:23:25.989: E/AndroidRuntime(3356): at android.os.AsyncTask$3.done(AsyncTask.java:299) 10-28 17:23:25.989: E/AndroidRuntime(3356): at java.util.concurrent.FutureTask.finishCompletion(FutureTask.java:352) 10-28 17:23:25.989: E/AndroidRuntime(3356): at java.util.concurrent.FutureTask.setException(FutureTask.java:219) 10-28 17:23:25.989: E/AndroidRuntime(3356): at java.util.concurrent.FutureTask.run(FutureTask.java:239) 10-28 17:23:25.989: E/AndroidRuntime(3356): at android.os.AsyncTask$SerialExecutor$1.run(AsyncTask.java:230) 10-28 17:23:25.989: E/AndroidRuntime(3356): at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1080) 10-28 17:23:25.989: E/AndroidRuntime(3356): at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:573) 10-28 17:23:25.989: E/AndroidRuntime(3356): at java.lang.Thread.run(Thread.java:856) 10-28 17:23:25.989: E/AndroidRuntime(3356): Caused by: java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare() 10-28 17:23:25.989: E/AndroidRuntime(3356): at android.os.Handler.<init>(Handler.java:197) 10-28 17:23:25.989: E/AndroidRuntime(3356): at android.os.Handler.<init>(Handler.java:111) 10-28 17:23:25.989: E/AndroidRuntime(3356): at android.widget.Toast$TN.<init>(Toast.java:324) 10-28 17:23:25.989: E/AndroidRuntime(3356): at android.widget.Toast.<init>(Toast.java:91) 10-28 17:23:25.989: E/AndroidRuntime(3356): at android.widget.Toast.makeText(Toast.java:238) 10-28 17:23:25.989: E/AndroidRuntime(3356): at com.aiman.webshopper.UploadImageActivity$1execMultiPostAsync.doInBackground(UploadImageActivity.java:268) 10-28 17:23:25.989: E/AndroidRuntime(3356): at com.aiman.webshopper.UploadImageActivity$1execMultiPostAsync.doInBackground(UploadImageActivity.java:1) 10-28 17:23:25.989: E/AndroidRuntime(3356): at android.os.AsyncTask$2.call(AsyncTask.java:287) 10-28 17:23:25.989: E/AndroidRuntime(3356): at java.util.concurrent.FutureTask.run(FutureTask.java:234) This is my code for the Upload activity: public class UploadImageActivity extends Activity implements OnItemSelectedListener { InputStream inputStream;

  • How to invoke the getView method in the baseAdapter in Android from another WebService Bean?

    - by greysh
    The adapter in my code as follows, I extends the base adapter: @Override public View getView(final int position, View convertView, ViewGroup parent) { ViewHolder vHolder; // if (convertView == null) { vHolder = new ViewHolder(); convertView = mInflater.inflate(R.layout.home_item, null); vHolder.albumIcon = (ImageView) convertView .findViewById(R.id.albumIcon); try { Bitmap icon = aws.getAlbumImg(itemInfolist.get(position) .getAlbumInfoCol().get(0).getAlbumID(), 0); if (icon != null) { vHolder.albumIcon.setImageBitmap(icon); } else { vHolder.albumIcon.setImageBitmap(BitmapFactory.decodeResource( context.getResources(), R.drawable.album)); } } catch (Exception e) { vHolder.albumIcon.setImageBitmap(BitmapFactory.decodeResource( context.getResources(), R.drawable.album)); } convertView.setTag(vHolder); return convertView; } However, I download the imagine asynchronously, When invoke Bitmap icon = aws.getAlbumImg(itemInfolist.get(position).getAlbumInfoCol().get(0).getAlbumID(), 0); Some pictures which haven't downloaded will use the default image, after these picutures have downloaded in another Web Service Bean, I want the Web Service bean sends a message to invoke the getView method in this adapter in order to implement the auto refresh function.

  • Unfortunately App stopped when destroying SupportMapFragment

    - by user1408341
    I have the following problem. I have three fragments which are hosted in a TabHost. When I'm working with the app everything works fine. Now I like to end the app when the user hits the back button. Instead of terminating without errors I get the message Unfortunately App stopped. Then I said to myself something is wrong with the onDestroy() method of the FragmentActivity or with the onDestroyView method() of the Fragment. The problem is I cannot debug the point where the app crash. I get only the error:Fatal signal 11 (SIGSEGV). I then removed one by one each Fragment to identify which fragment causes the error. I could identify the fragment that I named BasicMapFragment. Something is wrong there. The code: public class BasicMapFragment extends SupportMapFragment implements LocationListener { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View view = super.onCreateView(inflater, container, savedInstanceState); //removeAllMarkers(); //setupGps(); //setupMap(); //setupMarkersFromModel(); //registerListeners(); return view; } } I commented out all my self written code to isolate the place where the error occurs. @Override public void onDestroy() { Log.d("ch.xxx.fragment.BasiceMapFragment", "On destroy called"); super.onDestroy(); } public void onDestroyView() { Log.d("ch.xxx.fragment.BasiceMapFragment", "On destroy view called"); super.onDestroyView(); } When I press the back button now the onDestroy() method of my FragmentActivity is first called like expected. Then the onDestroyView method is called on my BasicMapFragment class. At the end the onDestroy method is called - and then the application crash. Here is my layout file: <?xml version="1.0" encoding="utf-8"?> <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent"> <fragment android:id="@+id/map" android:layout_width="match_parent" android:layout_height="match_parent" class="com.google.android.gms.maps.SupportMapFragment"/> </FrameLayout> Resume: - Map is showed - I can work with the app. - When I leave out the BasicMapFragment the app finish without error. - When I add the BasicMapFragment the app returns an error when I press the back button Is there something that I have forgot to implement? Have somebody had the same trouble?

  • Is this the best approach using generics to check for nulls

    - by user294747
    public static T IsNull<T>(object value, T defaultValue) { turn ((Object.Equals(value,null)) | (Object.Equals(value,DBNull.Value)) ? defaultValue : (T)value); } public static T IsNull<T>(object value) where T :new() { T defaultvalue = new T(); return IsNull(value, defaultvalue); } Have tested, and can use against data objects, classes and variables. Just want to know if there is better way to go about this.

  • Node.js Cron Job Messing with Date Object

    - by PazoozaTest Pazman
    I'm trying to schedule several cron jobs to generate serial numbers for different entities within my web app. However I am running into this problem, when I'm looping each table, it says it has something to do with date.js. I'm not doing anything with a date object ? Not at this stage anyway. A couple of guesses is that the cron object is doing a date thing in its code and is referencing date.js. I'm using date.js to get access to things like ISO date. for (t in config.generatorTables) { console.log("t = " + config.generatorTables[t] + "\n\n"); var ts3 = azure.createTableService(); var jobSerialNumbers = new cronJob({ //cronTime: '*/' + rndNumber + ' * * * * *', cronTime: '*/1 * * * * *', onTick: function () { //console.log(new Date() + " calling topUpSerialNumbers \n\n"); manageSerialNumbers.topUpSerialNumbers(config.generatorTables[t], function () { }); }, start: false, timeZone: "America/Los_Angeles" }); ts3.createTableIfNotExists(config.generatorTables[t], function (error) { if (error === null) { var query = azure.TableQuery .select() .from(config.generatorTables[t]) .where('PartitionKey eq ?', '0') ts3.queryEntities(query, function (error, serialNumberEntities) { if (error === null && serialNumberEntities.length == 0) { manageSerialNumbers.generateNewNumbers(config.maxNumber, config.serialNumberSize, config.generatorTables[t], function () { jobSerialNumbers.start(); }); } else jobSerialNumbers.start(); }); } }); } And this is the error message I'm getting when I examine the server.js.logs\0.txt file: C:\node\w\WebRole1\public\javascripts\date.js:56 onsole.log('isDST'); return this.toString().match(/(E|C|M|P)(S|D)T/)[2] == "D" ^ TypeError: Cannot read property '2' of null at Date.isDST (C:\node\w\WebRole1\public\javascripts\date.js:56:110) at Date.getTimezone (C:\node\w\WebRole1\public\javascripts\date.js:56:228) at Object._getNextDateFrom (C:\node\w\WebRole1\node_modules\cron\lib\cron.js:88:30) at Object.sendAt (C:\node\w\WebRole1\node_modules\cron\lib\cron.js:51:17) at Object.getTimeout (C:\node\w\WebRole1\node_modules\cron\lib\cron.js:58:30) at Object.start (C:\node\w\WebRole1\node_modules\cron\lib\cron.js:279:33) at C:\node\w\WebRole1\server.js:169:46 at Object.generateNewNumbers (C:\node\w\WebRole1\utils\manageSerialNumbers.js:106:5) at C:\node\w\WebRole1\server.js:168:45 at C:\node\w\WebRole1\node_modules\azure\lib\services\table\tableservice.js:485:7 I am using this line in my database.js file: require('../public/javascripts/date'); is that correct that I only have to do this once, because date.js is global? I.e. it has a bunch of prototypes (extensions) for the inbuilt date object. Within manageSerialNumbers.js I am just doing a callback, their is no code executing as I've commented it all out, but still receiving this error. Any help or advice would be appreciated.

  • Animation not start immediately when the target view is out of window

    - by funnything
    Hi. When I apply some animation to the view, which is out of window, the animation not start immediately. And then, I scroll the screen to show the animation target view, the animation will start. I hope to the animation will start immediately when it apply. Any ideas? Bellow is sample code. Thank you. public class AnimationValidationActivity extends Activity { private ViewSwitcher _viewSwitcher; private Button _button; /** * utility method for animation */ private Animation buildTranslateAnimation( float fromXDelta , float toXDelta , float fromYDelta , float toYDelta ) { Animation ret = new TranslateAnimation( fromXDelta , toXDelta , fromYDelta , toYDelta ); ret.setDuration( 1000 ); return ret; } /** * build view in place of layout.xml */ private View buildView() { ScrollView ret = new ScrollView( this ); ret.setLayoutParams( new LinearLayout.LayoutParams( LinearLayout.LayoutParams.FILL_PARENT , LinearLayout.LayoutParams.WRAP_CONTENT ) ); LinearLayout parent = new LinearLayout( this ); parent.setLayoutParams( new LinearLayout.LayoutParams( LinearLayout.LayoutParams.FILL_PARENT , LinearLayout.LayoutParams.WRAP_CONTENT ) ); parent.setOrientation( LinearLayout.VERTICAL ); ret.addView( parent ); _viewSwitcher = new ViewSwitcher( this ); _viewSwitcher.setLayoutParams( new LinearLayout.LayoutParams( LinearLayout.LayoutParams.FILL_PARENT , 100 ) ); parent.addView( _viewSwitcher ); View spacer = new View( this ); spacer.setLayoutParams( new LinearLayout.LayoutParams( LinearLayout.LayoutParams.FILL_PARENT , getWindow() .getWindowManager().getDefaultDisplay().getHeight() ) ); parent.addView( spacer ); _button = new Button( this ); _button.setText( "button" ); parent.addView( _button ); return ret; } @Override public void onCreate( Bundle savedInstanceState ) { super.onCreate( savedInstanceState ); setContentView( buildView() ); _viewSwitcher.setFactory( new ViewSwitcher.ViewFactory() { @Override public View makeView() { TextView view = new TextView( AnimationValidationActivity.this ); view.setLayoutParams( new ViewSwitcher.LayoutParams( ViewSwitcher.LayoutParams.FILL_PARENT , ViewSwitcher.LayoutParams.FILL_PARENT ) ); view.setBackgroundColor( 0xffffffff ); view.setText( "foobar" ); return view; } } ); _button.setOnClickListener( new View.OnClickListener() { @Override public void onClick( View v ) { _viewSwitcher.setInAnimation( buildTranslateAnimation( _viewSwitcher.getWidth() , 0 , 0 , 0 ) ); _viewSwitcher.setOutAnimation( buildTranslateAnimation( 0 , - _viewSwitcher.getWidth() , 0 , 0 ) ); int color = new Random().nextInt(); _viewSwitcher.getNextView().setBackgroundColor( 0xff000000 | color & 0xffffff ); _viewSwitcher.showNext(); } } ); } }

  • JPanel's child components paint/layout problem

    - by Tom Brito
    I'm having a problem that when my frame is shown (after a login dialog) the buttons are not on correct position, then in some miliseconds they go to the right position (the center of the panel with border layout). When I make a SSCCE, it works correct, but when I run my whole code I have this fast-miliseconds delay to the buttons to go to the correct place. Unfortunately, I can't post the whole code, but the method that shows the frame is: public void login(JComponent userView) { centerPanel.removeAll(); centerPanel.add(userView); centerPanel.revalidate(); centerPanel.repaint(); frame.setVisible(true); } What would cause this delay to the panel layout? (I'm running everything in the EDT) -- update In my machine, this SSCCE shows the layout problem in 2 of 10 times I run it: import java.awt.BorderLayout; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JPanel; import javax.swing.SwingUtilities; public class TEST { public static void main(String[] args) throws Exception { SwingUtilities.invokeAndWait(new Runnable() { @Override public void run() { System.out.println("Debug test..."); JPanel btnPnl = new JPanel(); btnPnl.add(new JButton("TEST")); JFrame f = new JFrame("TEST"); f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); f.getContentPane().setLayout(new BorderLayout()); f.getContentPane().add(btnPnl); f.pack(); f.setSize(800, 600); f.setVisible(true); System.out.println("End debug test!"); } }); } } The button first appers in the up-left, and then it goes to the center. Please, note that I'm understand, not just correct. Is it a java bug? --update OK, so the SSCCE don't show the problem with you that tried till now. Maybe it's my computer performance problem. But this don't answer the question, I still think Java Swing is creating new threads for make the layout behind the scenes.

  • Can I use an abstract class instead of a private __construct() when creating a singleton in PHP?

    - by Pheter
    When creating a Singleton in PHP, I ensure that it cannot be instantiated by doing the following: class Singleton { private function __construct() {} private function __clone() {} public static function getInstance() {} } However, I realised that defining a class as 'abstract' means that it cannot be instantiated. So is there anything wrong with doing the following instead: abstract class Singleton { public static function getInstance() {} } The second scenario allows me to write fewer lines of code which would be nice. (Not that it actually makes much of a difference.)
