  • Convert date to string upon saving a doctrine record

    - by takteek
    Hi, I'm trying to migrate one of my PHP projects to Doctrine. I've never used it before so there are a few things I don't understand. In my current code, I have a class similar to this: class ScheduleItem { private Date start; //A PEAR Date object. private Date end; public function getStart() { return $this-start; } public function setStart($val) { $this-start = $val; } public function getEnd() { return $this-end; } public function setEnd($val) { $this-end= $val; } } I have a ScheduleItemDAO class with methods like save(), getByID(), etc. When loading from and saving to the database, the DAO class converts the Date objects to and from strings so they can be stored in a timestamp field. In my attempt to move to Doctrine, I created a new class like this: class ScheduleItem extends Doctrine_Record { public function setTableDefinition() { $this-hasColumn('start', 'timestamp'); $this-hasColumn('end', 'timestamp'); } } I had hoped I would be able to use Date objects for the start and end times, and have them converted to strings when they are saved to the database. How can I accomplish this?

  • java: "downcasting" to new object / opposite of slicing

    - by rhavin
    Sorry, i really dont know how to make a headline for that question; maybe there is a name for what im trying to do that i dont know, but i can explain it with some code: Guess you have a class that unfortunately neither has a copy-constructor nor a public static copy method. class A { private int i; // <- private, cant access String x; // <- even worse: cant access unless in same pkg! /* … other stuff, ctor, etc. … */ public A clone() { A a = new A(); a.i = i; a.x = x; return x; } } Guess further, there is some function that returns an object of that class: public static A someFn(x,y,z); Now the problem: I want to derive from that class to add some functionality. Unfortunately, i neither have a sizeof in java nor a cc or static copy method. So when i do a class B extends A { protected w; public B clone() { /* as usual */ } } then i can clone my B and get a new one, but how can i convert the returned A from someFn() into a B. Is there anyway to do the opposite of slicing in java? if i clone it, it's still an A, and i cant copy it field by field. This is all simple in c++, but how to do this in Java?

  • zend session exception on zend_session::start with forms

    - by Grant Collins
    Hi I'm having issues with trying to use Zend_Form_SubForm and sessions. My controller is in essance acting a wizard showing different subforms depending on the stage of the wizard. Using the example I am planning on storing the forms in a session namespace. My controller looks like this. include 'mylib/Form/addTaskWizardForm.php'; class AddtaskController extends Zend_Controller_Action{ private $config = null; private $log = null; private $subFormSession = null; /** * This function is called and initialises the global variables to this object * which is the configuration details and the logger to write to the log file. */ public function init(){ $this->config = Zend_Registry::getInstance()->get('config'); $this->log = Zend_Registry::getInstance()->get('log'); //set layout $this->_helper->layout->setLayout('no-sidemenus'); //we need to get the subforms and $wizardForms = new addTaskWizardForm(); $this->subFormSession = new Zend_Session_Namespace('addTaskWizardForms'); if(!isset($this->subFormSession->subforms)){ $this->subFormSession->subforms = $wizardForms; } } /** * The Landing page controller for the site. */ public function indexAction(){ $form = $this->subFormSession->subforms->getSubForm('start'); $this->view->form = $form; } However this is causing the application session to crash out with Uncaught exception 'Zend_Session_Exception' with message 'Zend_Session::start() Any idea why this is having issues with the Zend Session?? thanks.

  • Download dynaic file with GWT

    - by Maksim
    I have a GWT page where user enter data (start date, end date, etc.), then this data goes to the server via RPC call. On the server I want to generate Excel report with POI and let user save that file on their local machine. This is my test code to stream file back to the client but for some reason it does not know: public class ReportsServiceImpl extends RemoteServiceServlet implements ReportsService { public String myMethod(String s) { File f = new File("/excelTestFile.xls"); String filename = f.getName(); int length = 0; try { HttpServletResponse resp = getThreadLocalResponse(); ServletOutputStream op = resp.getOutputStream(); ServletContext context = getServletConfig().getServletContext(); resp.setContentType("application/octet-stream"); resp.setContentLength((int) f.length()); resp.setHeader("Content-Disposition", "attachment; filename*=\"utf-8''" + filename + ""); byte[] bbuf = new byte[1024]; DataInputStream in = new DataInputStream(new FileInputStream(f)); while ((in != null) && ((length = in.read(bbuf)) != -1)) { op.write(bbuf, 0, length); } in.close(); op.flush(); op.close(); } catch (Exception ex) { ex.printStackTrace(); } return "Server says: " + filename; } } I've red somewhere on internet that you can't do file stream with RPC and I have to use Servlet for that. Is there any example of how to use Servlet and how to call that servlet from ReportsServiceImpl

  • Android: onListItemClick not opening up the .xml file

    - by Capsud
    Hi, public void onListItemClick(ListView l, View v, int position, long id) { if(position == 0){ setContentView(R.layout.cuisine); } } I have an array of Strings and i'm using the above method to try and open up a new xml file called 'cuisine' when it is clicked. but it keeps failing! Have I done this right, or what am I doing wrong? Thanks. Ok from looking at similar problems on the web, people have said to get the onListItemClick() to start a new activity and using that new activity to then open up the new view? So what i've done is this... protected void onListItemClick(ListView l, View v, int position, long id) { Intent dundrumIntent = new Intent(v.getContext(), DundrumSelector.class); dundrumIntent.putExtra("position", position); startActivityForResult(dundrumIntent, 0); } and then import android.app.Activity; import android.os.Bundle; public class DundrumSelector extends Activity { @Override public void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); int position = getIntent().getExtras().getInt("position"); if(position == 0){ setContentView(R.layout.cuisine); } } } Yet i'm still getting the same problem. The program crashes when I click on an item in the listView. And yes i've added the activity to the manifest. Does anyone have a resolution to this as alot of people seem to be having the same problem. Thanks alot.

  • [MySQL/PHP] Avoid using RAND()

    - by Andrew Ellis
    So... I have never had a need to do a random SELECT on a MySQL DB until this project I'm working on. After researching it seems the general populous says that using RAND() is a bad idea. I found an article that explains how to do another type of random select. Basically, if I want to select 5 random elements, I should do the following (I'm using the Kohana framework here)? If not, what is a better solution? Thanks, Andrew <?php final class Offers extends Model { /** * Loads a random set of offers. * * @param integer $limit * @return array */ public function random_offers($limit = 5) { // Find the highest offer_id $sql = ' SELECT MAX(offer_id) AS max_offer_id FROM offers '; $max_offer_id = DB::query(Database::SELECT, $sql) ->execute($this->_db) ->get('max_offer_id'); // Check to make sure we're not trying to load more offers // than there really is... if ($max_offer_id < $limit) { $limit = $max_offer_id; } $used = array(); $ids = ''; for ($i = 0; $i < $limit; ) { $rand = mt_rand(1, $max_offer_id); if (!isset($used[$rand])) { // Flag the ID as used $used[$rand] = TRUE; // Set the ID if ($i > 0) $ids .= ','; $ids .= $rand; ++$i; } } $sql = ' SELECT offer_id, offer_name FROM offers WHERE offer_id IN(:ids) '; $offers = DB::query(Database::SELECT, $sql) ->param(':ids', $ids) ->as_object(); ->execute($this->_db); return $offers; } }

  • Android: How to put ListView in XML?

    - by FloIancu
    I want to make a simple app that shows a list of contacts (name, surname). My code: package lista.android; import java.util.*; import android.app.ListActivity; import android.os.Bundle; import android.widget.*; class Contact{ String nume; String prenume; Contact(String nume, String prenume){ this.nume=nume; this.prenume=prenume; } public String toString(){ return prenume +" "+ nume; } } public class Lista1Activity extends ListActivity { /** Called when the activity is first created. */ ArrayList <Contact> lista; ArrayAdapter <Contact> adaptor; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); setListAdapter(adaptor); lista=new ArrayList<Contact>(); adaptor=new ArrayAdapter<Contact>(this, R.id.element, lista); adaugaContact("Florian", "Iancu"); adaugaContact("Ioana", "Constantina"); } public void adaugaContact(String nume, String prenume){ lista.add(new Contact(nume, prenume)); adaptor.notifyDataSetChanged(); } } In the XML I have the LinearLayout and a TextView that is the list element. When I run it, the simulator says "Sorry, the application [...] has stopped unexpectedly. Please try again." The LogCat tells me I have to have a ListView whose id is android.R.id.lista. If I create a random ListView field in the XML file and give it the "lista" id, it still doesn't work. How to I call that ListView from XML to match something in my Java code? In other words, I know I'm wrong, but where and how do I fix it?

  • Syntax error results in blank page

    - by Philipp
    I am new to wicket and trying to get some things working. One thing that annoys me a lot is that I get a blank (0 chars of text) page whenever there is a syntax error on a page. Striped down example: Test.html header stuff: doctype ... html ... head ... body ... <span wicket:id="msgTest" id="message">MSG</span> footer stuff: /body ... /html Test.java public class Test extends WebPage { public Test() { add(new Label("msgTest", "Hello, World!")); } } This will output the page as expected. Now, lets introduce an error: header stuff: doctype ... html ... head ... body ... <span wicket:id="msgTest2" id="message">MSG</span> footer stuff: /body ... /html I changed the label-id to something different then what the source-file expects. If I run this code I get the already mentioned blank page. However, for every request to a page with such a syntax error I get an error report in the log-file of around 1000+ lines. This error-report is basically just wicket-generated html of a page which describes the error. This makes me wonder why wicket isn't displaying the error-stuff instead of the blank page. I'm not very experienced with wicket but to me it somehow looks like wicket is having trouble rendering its own error-page code. It would be nice to know how one goes about finding syntax-errors with wicket. Reading through a 1000+ line error-report for a small error like a misplaced character seems a bit tedious. Thanks in advance for guiding me into the right direction :) PS: wicket-version: 1.4.9 stage: development

  • How to Get user input from a Text Entry Box in Android?

    - by NewGuy
    in an android website, I found an article about how to create a text entry widget that provides auto-complete suggestions. (Following is the link to the site; and it shows all the codes). http://developer.android.com/resources/tutorials/views/hello-autocomplete.html Can anyone please tell me how I can capture the input entered by the user? For example, if the user chooses “Canada”, is there a way I can know the result in the “HelloAutoComplete.java” activity? Any help would be greatly appreciated. public class HelloAutoComplete extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); AutoCompleteTextView textView = (AutoCompleteTextView) findViewById(R.id.autocomplete_country); String[] countries = getResources().getStringArray(R.array.countries_array); ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.list_item, countries); textView.setAdapter(adapter); textView.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() { public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) { if (adapterView.getItemAtPosition(i).toString().equals("Canada")) { Toast.makeText(getApplicationContext(), "Result Canada", Toast.LENGTH_SHORT).show(); } //Does not get an out put when I select Canada. } public void onNothingSelected(AdapterView<?> adapterView) { } }); } }

  • How can I find out if the MainActivity is being paused from my Java class?

    - by quinestor
    I am using motion sensor detection in my application. My design is this: a class gets the sensor services references from the main activity and then it implements SensorEventListener. That is, the MainActivity does not listen for sensor event changes: public void onCreate(Bundle savedInstanceState) { // ... code mSensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE); mAccelerometer = mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER); // The following is my java class, it does not extends any android fragment/activty mShakeUtil = new ShakeUtil(mSensorManager,mAccelerometer,this); // ..more code.. } I can't redesign ShakeUtil so it is a fragment nor activity, unfortunately. Now to illustrate the problem consider: MainActivity is on its way to be destroyed/paused. I.e screen rotation ShakeUtil's onSensorChanged(SensorEvent event) gets called in the process.. One of the things that happen inside onSensorChanged is a dialog interaction, which gives the error: java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState When the previous happens between MainActivity's onSaveInstanceState and onPause. I know this can be prevented if I successfully detect that MainActivity is being pause in ShakeUtil. How can I detect that MainActivity is being paused or onSaveInstanceState was called from ShakeUtil? Alternatively, how can I avoid this issue without making Shakeutil extend activity? So far I have tried with flag variables but that isn't good enough, I guess these are not atomic operations. I tried using Activity's isChangingConfigurations(), but I get an undocummented "NoSuchMethodFound" error.. I am unregistering the sensors by calling ShakeUtil when onPause in main ACtivity

  • Android, NetworkInfo.getTypeName(), NullpointerException

    - by moppel
    I have an activity which shows some List entries. When I click on a list item my app checks which connection type is available ("WIF" or "MOBILE"), through NetworkInfo.getTypeName(). As soon as I call this method I get a NullpointerException. Why? I tested this on the emulator, cause my phone is currently not available (it's broken...). I assume this is the problem? This is the only explanation that I have, if that's not the case I have no idea why this would be null. Here's some code snippet: public class VideoList extends ListActivity{ ... public void onCreate(Bundle bundle){ final ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE); ... listview.setOnItemClickListener(new OnItemClickListener(){ public void onItemClick(AdapterView<?> parent, View view, int position, long id) { ... NetworkInfo ni = cm.getActiveNetworkInfo(); String connex = ni.getTypeName(); //Nullpointer exception here if(connex.equals("WIFI")doSomething(); } }); } }

    Hi there, Bear with me as i'm just learning about Android. What i'm trying to do is to open an Activity when i click on a button. This is my code in my main activity public class MainPage extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Button restaurants = (Button) findViewById(R.id.widget88); restaurants.setOnClickListener(new View.OnClickListener() { public void onClick(View view) { Intent myIntent = new Intent(view.getContext(), AZRestaurants.class); startActivityForResult(myIntent, 0); } }); //Button location = (Button) findViewById(R.id.location); //location.setOnClickListener(new View.OnClickListener() { //public void onClick(View view) { // Intent myIntent = new Intent(view.getContext(), Location.class); // startActivity(myIntent); //} // }); } The program launches no problem when i just implement the first button (restuarant).

  • How to find which file is open in eclipse editor without using IEditorPart?

    - by Destructor
    I want to know which file (or even project is enough) is opened in eclipse editor? I know we can do this once we get IEditorPart from doSetInput method, IFile file = ((IFileEditorInput) iEditorPart).getFile(); But I want the name of file without using IEditorPart, how can I do the same? Checking which is the selected file in project explorer is not of much help because, user can select multiple files at once and open all simultaneously and I did not way to distinguish which file opened at what time. Adding more info: I have an editor specified for a particular type of file, now every time it opens, during intializing editor I have some operation to do based on project properties. While initializing editor, I need the file handle (of the one which user opened/double clicked) or the corresponding project handle. I have my editor something this way: public class MyEditor extends TextEditor{ @Override protected void initializeEditor() { setSourceViewerConfiguration(new MySourceViewerConfiguration( CDTUITools.getColorManager(), store, "MyPartitions", this)); } //other required methods @Override protected void doSetInput(IEditorInput input) throws CoreException { if(input instanceof IFileEditorInput) { IFile file = ((IFileEditorInput) input).getFile(); } } } as I have done in the doSetInput() method , I want the file handle(even project handle is sufficient). But the problem is in initializeEditor() function there is no reference to editorInput, hence I am unable to get the file handle. In the source viewer configuration file, I set the code scanners and this needs some project specific information that will set the corresponding rules.

Thanks public class MyFragment extends Fragment { Calendar mCalendar; private Runnable mTicker; private Handler mHandler; TextView mClock; String mFormat; private boolean mClockStopped = false; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { RelativeLayout view = (RelativeLayout) inflater.inflate(R.layout.meteo_widget, container, false); /* * Clock (from DigitalClock widget source) */ mClock = (TextView) view.findViewById(R.id.clock); mCalendar = Calendar.getInstance(); mHandler = new Handler(); mTicker = new Runnable() { public void run() { if(mClockStopped) return; mCalendar.setTimeInMillis(System.currentTimeMillis()); mClock.setText(DateFormat.format("hh:mm:ss", mCalendar)); mClock.invalidate(); long now = SystemClock.uptimeMillis(); long next = now + (1000 - now % 1000); mHandler.postAtTime(mTicker, next); } }; mTicker.run(); return view; } @Override public void onResume() { super.onResume(); mClockStopped = true; } @Override public void onPause() { mClockStopped = false; super.onPause(); } }

  • Generic callbacks

    - by bobobobo
    Extends So, I'm trying to learn template metaprogramming better and I figure this is a good exercise for it. I'm trying to write code that can callback a function with any number of arguments I like passed to it. // First function to call int add( int x, int y ) ; // Second function to call double square( double x ) ; // Third func to call void go() ; The callback creation code should look like: // Write a callback object that // will be executed after 42ms for "add" Callback<int, int, int> c1 ; c1.func = add ; c1.args.push_back( 2 ); // these are the 2 args c1.args.push_back( 5 ); // to pass to the "add" function // when it is called Callback<double, double> c2 ; c2.func = square ; c2.args.push_back( 52.2 ) ; What I'm thinking is, using template metaprogramming I want to be able to declare callbacks like, write a struct like this (please keep in mind this is VERY PSEUDOcode) <TEMPLATING ACTION <<ANY NUMBER OF TYPES GO HERE>> > struct Callback { double execTime ; // when to execute TYPE1 (*func)( TYPE2 a, TYPE3 b ) ; void* argList ; // a stored list of arguments // to plug in when it is time to call __func__ } ; So for when called with Callback<int, int, int> c1 ; You would automatically get constructed for you by < HARDCORE TEMPLATING ACTION > a struct like struct Callback { double execTime ; // when to execute int (*func)( int a, int b ) ; void* argList ; // this would still be void*, // but I somehow need to remember // the types of the args.. } ; Any pointers in the right direction to get started on writing this?

  • What if a large number of objects are passed to my SwingWorker.process() method?

    - by Trejkaz
    I just found an interesting situation. Suppose you have some SwingWorker (I've made this one vaguely reminiscent of my own): public class AddressTreeBuildingWorker extends SwingWorker<Void, NodePair> { private DefaultTreeModel model; public AddressTreeBuildingWorker(DefaultTreeModel model) { } @Override protected Void doInBackground() { // Omitted; performs variable processing to build a tree of address nodes. } @Override protected void process(List<NodePair> chunks) { for (NodePair pair : chunks) { // Actually the real thing inserts in order. model.insertNodeInto(parent, child, parent.getChildCount()); } } private static class NodePair { private final DefaultMutableTreeNode parent; private final DefaultMutableTreeNode child; private NodePair(DefaultMutableTreeNode parent, DefaultMutableTreeNode child) { this.parent = parent; this.child = child; } } } If the work done in the background is significant then things work well - process() is called with relatively small lists of objects and everything is happy. Problem is, if the work done in the background is suddenly insignificant for whatever reason, process() receives a huge list of objects (I have seen 1,000,000, for instance) and by the time you process each object, you have spent 20 seconds on the Event Dispatch Thread, exactly what SwingWorker was designed to avoid. In case it isn't clear, both of these occur on the same SwingWorker class for me - it depends on the input data, and the type of processing the caller wanted. Is there a proper way to handle this? Obviously I can intentionally delay or yield the background processing thread so that a smaller number might arrive each time, but this doesn't feel like the right solution to me.

  • Eclipse-plugin: Can't see my results in AbstractTextSearchViewPage

    - by Jason Kealey
    I've implemented a ISearchQuery and ISearchResult. They get loaded into my class that extends AbstractTextSearchViewPage. I'm using some code taken from the FileSearchPage to show the results in both a TreeViewer and a TableViewer. protected void configureTableViewer(TableViewer viewer) { viewer.setUseHashlookup(true); FileLabelProvider innerLabelProvider = new FileLabelProvider(this, FileLabelProvider.SHOW_LABEL_PATH); viewer.setLabelProvider(new DecoratingLabelProvider(innerLabelProvider, PlatformUI.getWorkbench().getDecoratorManager().getLabelDecorator())); viewer.setContentProvider(new UrnTableContentProvider(this)); viewer.setComparator(new DecoratorIgnoringViewerSorter(innerLabelProvider)); fContentProvider = (IFileSearchContentProvider) viewer.getContentProvider(); } protected void configureTreeViewer(TreeViewer viewer) { viewer.setUseHashlookup(true); FileLabelProvider innerLabelProvider = new FileLabelProvider(this, FileLabelProvider.SHOW_LABEL_PATH); viewer.setLabelProvider(new DecoratingLabelProvider(innerLabelProvider, PlatformUI.getWorkbench().getDecoratorManager().getLabelDecorator())); viewer.setContentProvider(new UrnTreeContentProvider(this, viewer)); viewer.setComparator(new DecoratorIgnoringViewerSorter(innerLabelProvider)); fContentProvider = (IFileSearchContentProvider) viewer.getContentProvider(); } When searching using the regular file search, each individual result is visible under the file and the label says "(X matches)". In my own editor, however, I only see the file with X matches found inside that file, but I don't see the details in either the TreeViewer or the TableViewer. Any tips?
