  • Autowire not working in junit test

    - by Dave Paroulek
    I'm sure I'm missing something simple. bar gets autowired in the junit test, but why doesn't bar inside foo get autowired? @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration({"beans.xml"}) public class BarTest { @Autowired Object bar; @Test public void testBar() throws Exception { //this works assertEquals("expected", bar.someMethod()); //this doesn't work, because the bar object inside foo isn't autowired? Foo foo = new Foo(); assertEquals("expected", foo.someMethodThatUsesBar()); } }

  • Help with data retrieval MACRO

    - by Andrei Ciobanu
    Hello, given the following structure: struct nmslist_elem_s { nmptr data; struct nmslist_elem_s *next; }; typedef struct nmslist_elem_s nmslist_elem; Where: typedef void* nmptr; Is it possible to write a MACRO that retrieves the data from the element and cast it to the right type: MACRO(type, element) that expands to *((type*)element->data). For example for int, i would need something like this: *((int*)(element->data)) .

  • Android - cant read TXT files from SDcard on real mashine?

    - by JustMe
    Hello! When I run the code bellow in the virtual android (1.5) it works well, TextSwitcher shows first 80 chars from each txt file from /sdcard/documents/ , but when I run it on my Samsung Galaxy i7500 (1.6) there are no contents in TextSwitcher, however in LogCat there are FileNames of txt files. My Code: public void getTxtFiles(){ //Scan /sdcard/documents and put .txt files in array File TxtFiles[] String path = Environment.getExternalStorageDirectory().toString()+"/documents/"; String files; File folder = new File(path); if(folder.exists()==false){if (!folder.mkdirs()) { Log.e("TAG", "Create dir in sdcard failed"); return; }} else{ File listOfFiles[] = folder.listFiles(); for (int i = 0; i < listOfFiles.length; i++) { if (listOfFiles[i].isFile()) { files = listOfFiles[i].getName(); if (files.endsWith(".txt") || files.endsWith(".TXT")) { if((files.length()-1)>i){resizeArray(TxtFiles, files.length()+10);} TxtFiles[i]=listOfFiles[i]; System.out.println(TxtFiles[i]); } } }} } private void updateCounter(int Pozicija) { if(Pozicija<0){Toast.makeText(getApplicationContext(), R.string.LastTxt, 5).show(); mCounter++;} else if(TxtFiles[mCounter]!=null){ TextToShow = getContents(TxtFiles[mCounter]); if(TextToShow.length()>80)TextToShow=TextToShow.substring(0, 80); mSwitcher.setText(TextToShow); System.out.println(Pozicija); } else mCounter--; } static public String getContents(File aFile) { //...checks on aFile are elided StringBuilder contents = new StringBuilder(); try { //use buffering, reading one line at a time //FileReader always assumes default encoding is OK! BufferedReader input = new BufferedReader(new FileReader(aFile)); try { String line = null; //not declared within while loop /* * readLine is a bit quirky : * it returns the content of a line MINUS the newline. * it returns null only for the END of the stream. * it returns an empty String if two newlines appear in a row. */ while (( line = input.readLine()) != null){ contents.append(line); contents.append(System.getProperty("line.separator")); } } finally { input.close(); } } catch (IOException ex){ ex.printStackTrace(); } return contents.toString(); } And I am able to write contents of those files though LogCat! Any ideas?

    Hi I have a velocity ivar defined as a CGPoint.

Do I then need to convert or cast this result before calling my adjustTimer method?

  • Disposing the members that implement IDisposable.

    - by Amby
    In my Dispose methods (like the one below), everytime i want to call someObj.Dispose() i also have a check for someObj!=null. Is that because of bad design on my part? Is their a cleaner way to ascertain that Dispose of all the members (implementing IDisposable) being used in an object is called without having a risk of NullReference exception ? protected void Dispose(bool disposing) { if (disposing) { if (_splitTradePopupManager != null) { _splitTradePopupManager.Dispose(); } } } Thanks for your interest.

  • How to generate NUnit fixtures programmatically?

    - by pmezard
    Hello, Say I have a test like: void TestSomething(int someParam) { // Test code } I would like to execute this test with a set of "someParam" values. I could write explicit [Test] fixtures calling TestSomething() with the parameters, which means having N methods for every TestSomething() method. I could write another [Test] method looping on "someParam" values and calling TestSomething(), it means 2 methods for every test, and the test report is not as good as with individual TestSomethingWithXValue() methods. So, is there any way to programmatically generate fixtures for every test methods and input values?

  • ScheduledExecutorService throwable lost

    - by Andrey
    Hello, Consider I scheduled a Runnable for periodic execution with ScheduledExecutorService and there occurs some system Error like OutOfMemory. It will be silently swallowed. scheduler.scheduleWithFixedDelay(new Runnable() { @Override public void run() { throw new OutOfMemoryError(); // Swallowed } }, 0, delay, TimeUnit.SECONDS); Is it normal? Why doesn't it propagate to the container? What is the correct way to handle such errors? Thanks!

How do I stop this thread?

  • Creating a "permanent" Cocoa object

    - by quixoto
    I have an object factory that hands out instances of certain "constant" objects. I'd like these objects to be protected against bad memory management by clients. This is how I've overridden the class's key methods. Am I missing anything (code or other considerations)? - (id)retain { return self; } - (NSUInteger)retainCount { return UINT_MAX; } - (void)release { // nothing. }

  • Displaying a notification when bluetooth is disconnected - Android

    - by Ryan T
    I am trying to create a program that will display a notification to the user if a Blue tooth device suddenly comes out of range from my Android device. I currently have the following code but no notification is displayed. I was wondering if it was possible I shouldn't use ACTION_ACL_DISCONNECTED because I believe the bluetooth stack would be expecting packets that state a disconnect is requested. My requirements state that the bluetooth device will disconnect without warning. Thank you for any assistance! BluetoothNotification.java: //This is where the notification is created. import android.app.Activity; import android.app.Notification; import android.app.NotificationManager; import android.app.PendingIntent; import android.content.Context; import android.content.Intent; import android.os.Bundle; import android.app.Activity; import android.app.Notification; import android.app.NotificationManager; import android.app.PendingIntent; import android.content.Context; import android.content.Intent; import android.os.Bundle; public class BluetoothNotification extends Activity { public static final int NOTIFICATION_ID = 1; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); /** Define configuration for our notification */ int icon = R.drawable.logo; CharSequence tickerText = "This is a sample notification"; long when = System.currentTimeMillis(); Context context = getApplicationContext(); CharSequence contentTitle = "Sample notification"; CharSequence contentText = "This notification has been generated as a result of BT Disconnecting"; Intent notificationIntent = new Intent(this, BluetoothNotification.class); PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0); /** Initialize the Notification using the above configuration */ final Notification notification = new Notification(icon, tickerText, when); notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent); /** Retrieve reference from NotificationManager */ String ns = Context.NOTIFICATION_SERVICE; final NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns); mNotificationManager.notify(NOTIFICATION_ID, notification); finish(); } } Snippet from OnCreate: //Located in Controls.java IntentFilter filter1 = new IntentFilter(BluetoothDevice.ACTION_ACL_DISCONNECTED); this.registerReceiver(mReceiver, filter1); Snippet from Controls.java: private final BroadcastReceiver mReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { String action = intent.getAction(); BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE); if (BluetoothDevice.ACTION_ACL_DISCONNECTED.equals(action)) { //Device has disconnected NotificationManager nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE); } } };
