  • Calling Model Functions from a Library

    - by Abs
    Hello all, I have turned a normal PHP class into a library so I can use it in Codeigniter as a library. I can load it and call the functions I need in that class. Here is that class to help with the question. However, there are quite a few points where I have to call functions in my class. These functions reside in the model that instantiated my class. How can I do this as currently normal calls don't work. Here is my code: class Controlpanel_model extends Model { var $category = ''; var $dataa = 'a'; function Controlpanel_model(){ parent::Model(); } function import_browser_bookmarks(){ $this->load->library('BookmarkParser'); /* *In this function call to the class I pass * what model functions exist that it should call * You can view how this done by clicking the link above and looking at line 383 */ $this->bookmarkparser->parseNetscape("./bookmarks.html", 0, 'myURL', 'myFolder'); return $this->dataa; } function myURL($data, $depth, $no) { $category = $this->category; $this->dataa .= 'Tag = '.$category.'<br />'.'URL = '.$data["url"].'<br />'.'Title = '.$data["descr"].'<br />'.'<br /><br />'; } function myFolder($data, $depth, $no) { $this->category = $data["name"]; } } Thanks all for any help.

  • How to get the path of a derived class from an inherited method?

    - by Jacco
    How to get the path of the current class, from an inherited method? I have the following: <?php // file: /parentDir/class.php class Parent { protected function getDir() { return dirname(__FILE__); } } ?> and <?php // file: /childDir/class.php class Child extends Parent { public function __construct() { echo $this->getDir(); } } $tmp = new Child(); // output: '/parentDir' ?> The __FILE__ constant always points to the source-file of the file it is in, regardless of inheritance. I would like to get the name of the path for the derived class. Is there any elegant way of doing this? I could do something along the lines of $this->getDir(__FILE__); but that would mean that I have to repeat myself quite often. I'm looking for a method that puts all the logic in the parent class, if possible. Update: Accepted solution (by Palantir): <?php // file: /parentDir/class.php class Parent { protected function getDir() { $reflector = new ReflectionClass(get_class($this)); return dirname($reflector->getFileName()); } } ?>

  • In listview,Viewstub cannot be found after the previous one is inflate

    - by user2958132
    I am using some list item layout and in the item layout, there is a Viewstub where I want to put some image in.I don't have the source of list item layout and just know there are some TextViews and ViewStubs in it. My purpose is to find the ViewStub first and set my personal layout and play with it. However, some of the ViewStub cannot be found. public class TJAdapter extends CursorAdapter { .... public void bindView(View view, Context context, Cursor cursor) { ViewStub contentstub = (ViewStub)item.findViewById(R.id.content_stub); if (contentstub == null){ LOG.error("TJ,contentstub is null"); } else { LOG.error("TJ,contentstub is not null"); contentstub.setLayoutResource(R.layout.icon_image); View iconImage = contentstub.inflate(); } .... } public View newView(Context context, Cursor cursor, ViewGroup parent) { final View view = mInflater.inflate(R.layout.list_item, parent, false); bindView(view, context, cursor); } And the log output is like this: TJ,bindView is called TJ,contentstub is not null TJ,bindView is called TJ,contentstub is null TJ,bindView is called TJ,contentstub is not null TJ,bindView is called TJ,contentstub is not null TJ,bindView is called TJ,contentstub is null TJ,bindView is called TJ,contentstub is not null I spent a lot of time on it and have no idea why this happens. Can some body help?

  • Silverlight: how to use a scroll viewer to wrap a list view without specifying height?

    - by John Nicholas
    I have a control that has a list that varies in length greatly. This control appears in various places meaning that i cannot calculate its position and desired height easily. Moreover all I want is for the scrollviewer to simply size itself according to its parent. currently it insists on sizing itself according to the content. currently when i have a list that exceeds the height of the screen the whole control extends off the bottom and the scrollviewer shows no bar (because it has stretched to the heigth of the contents and so thinks it is not required). I've not included code as the object graph is fairly deep. What i am looking for is a set of conditions that would cause the scrollviewer to resize itself according to its content rather than its parent. I have it working in a similar situation involving grids and datagrids, the unique part of this control is that there is a list containing controls. Any ideas? I would prefer solutions that don't require use of code behind - but im really not in a position to be choosey.

  • Android: Can not send http post

    - by jpartogi
    Hi all, I've been banging my head trying to figure out how to send a post method in Android. This is how my code look like: public class HomeActivity extends Activity implements OnClickListener { private TextView textView; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); textView = (TextView) findViewById(R.id.text); Button button = (Button)findViewById(R.id.button); button.setOnClickListener(this); } @Override public void onClick(View view) { HttpPost httpMethod = new HttpPost("http://www.example.com/"); httpMethod.addHeader("Accept", "text/html"); httpMethod.addHeader("Content-Type", "application/xml"); AndroidHttpClient client = AndroidHttpClient.newInstance("Android"); String result = null; try { HttpResponse response = client.execute(httpMethod); textView.setText(response.toString()); HttpEntity entity = response.getEntity(); Log.i(HomeActivity.class.toString(), result); textView.setText("Invoked webservice"); } catch (IOException e) { e.printStackTrace(); Log.e(HomeActivity.class.toString(), e.getMessage()); textView.setText("Something wrong:" + e.getMessage()); } } } What am I doing wrong here? Is there anything that I may need to configure from the Android emulator to get this working? Thank you for your help.

  • how can I write a schema that produce an unordered xml with extension

    - by ekeren
    In the following schema I am trying to make an unordered xml that extends simpleConfigurationObject: <xs:complexType name="forTestingConfigurationObjectCreator"> <xs:complexContent> <xs:extension base="simpleConfigurationObject"> <xs:all> <xs:element name="a" type="xs:string"/> <xs:element name="b" type="xs:string" minOccurs="0"/> </xs:all> </xs:extension> </xs:complexContent> </xs:complexType> <xs:complexType name="simpleConfigurationObject"> <xs:all> <xs:element name="base" type="xs:string" minOccurs="0"/> </xs:all> </xs:complexType> But I get the following error on the xs:all "all is not the only particle in the group, or is being used as an extension" (which is correct) Off-course if put the base element inside the xs:all and not use xs:extension at all I will get an unordered schema restriction. (but that is not what I want) The question is: how can I produce unordered schema with the extension? Thanks

  • Reading component parameters and setting defaults

    - by donut
    I'm pulling my hair on this because it should be simple, but can't get it to do the right thing. What's the best practice way of doing the following I've created a custom component that extends <s:Label> so now the Label has additional properties color2 color3 value which can be called like this and are used in the skin. <s:CustomLabel text="Some text" color2="0x939202" color3="0x999999" value="4.5" /> If I don't supply these parameters, I'd like some defaults to be set. So far I've had some success, but it doesn't work 100% of the time, which leads me to think that I'm not following best practices when setting those defaults. I do it now like this: [Bindable] private var myColor2:uint = 0x000000; [Bindable] private var myColor3:uint = 0x000000; [Bindable] private var myValue:Number = 10.0; then in the init function, I do a variation of this to set the default myValue = hostComponent.value; myValue = (hostComponent.value) ? hostComponent.value : 4.5; Sometimes it works, sometimes it doesn't, depending on the type of variable I'm trying to set. I eventually decided to read them as Strings then convert them to the desired type, but it seems that this also works half the time.

  • Content-disposition:inline header won't show images inline?

    - by hamstar
    I'm trying to show an image inline on a page. It is being served by a codeigniter controller. class Asset extends MY_Controller { function index( $folder, $file ) { $asset = "assets/$folder/$file"; if ( !file_exists( $asset ) ) { show_404(); return; } switch ( $folder ) { case 'css': header('Content-type: text/css'); break; case 'js': header('Content-type: text/javascript'); break; case 'images': $ext = substr( $file, strrpos($file, '.') ); switch ( $ext ) { case 'jpg': $ext = 'jpeg'; break; case 'svg': $ext = 'svg+xml'; break; } header('Content-Disposition: inline'); header('Content-type: image/'.$ext); } readfile( $asset ); } } When I load a image in Chrome of FF its pops up the download window. I know when the browser can't display the content inline it will force a download anyway, but these are PNG and GIF images which display in the browser fine otherwise. In IE it doesn't force a download but it displays the image in ASCII. If I comment out the entire image case it FF and Chrome both display the ASCII but not the image. I thought setting the content type would allow FF and Chrome to show the actual image, and also allow the location to be used as an src. The javascript and css shows fine of course. Anyone got any ideas how I can make the images show properly? Thanks :)

  • Django - Override admin site's login form

    - by TrojanCentaur
    I'm currently trying to override the default form used in Django 1.4 when logging in to the admin site (my site uses an additional 'token' field required for users who opt in to Two Factor Authentication, and is mandatory for site staff). Django's default form does not support what I need. Currently, I've got a file in my templates/ directory called templates/admin/login.html, which seems to be correctly overriding the template used with the one I use throughout the rest of my site. The contents of the file are simply as below: # admin/login.html: {% extends "login.html" %} The actual login form is as below: # login.html: {% load url from future %}<!DOCTYPE html> <html> <head> <title>Please log in</title> </head> <body> <div id="loginform"> <form method="post" action="{% url 'id.views.auth' %}"> {% csrf_token %} <input type="hidden" name="next" value="{{ next }}" /> {{ form.username.label_tag }}<br/> {{ form.username }}<br/> {{ form.password.label_tag }}<br/> {{ form.password }}<br/> {{ form.token.label_tag }}<br/> {{ form.token }}<br/> <input type="submit" value="Log In" /> </form> </div> </body> </html> My issue is that the form provided works perfectly fine when accessed using my normal login URLs because I supply my own AuthenticationForm as the form to display, but through the Django Admin login route, Django likes to supply it's own form to this template and thus only the username and password fields render. Is there any way I can make this work, or is this something I am just better off 'hard coding' the HTML fields into the form for?

  • Oracle T4CPreparedStatement memory leaks?

    - by Jay
    A little background on the application that I am gonna talk about in the next few lines: XYZ is a data masking workbench eclipse RCP application: You give it a source table column, and a target table column, it would apply a trasformation (encryption/shuffling/etc) and copy the row data from source table to target table. Now, when I mask n tables at a time, n threads are launched by this app. Here is the issue: I have run into a production issue on first roll out of the above said app. Unfortunately, I don't have any logs to get to the root. However, I tried to run this app in test region and do a stress test. When I collected .hprof files and ran 'em through an analyzer (yourKit), I noticed that objects of oracle.jdbc.driver.T4CPreparedStatement was retaining heap. The analysis also tells me that one of my classes is holding a reference to this preparedstatement object and thereby, n threads have n such objects. T4CPreparedStatement seemed to have character arrays: lastBoundChars and bindChars each of size char[300000]. So, I researched a bit (google!), obtained ojdbc6.jar and tried decompiling T4CPreparedStatement. I see that T4CPreparedStatement extends OraclePreparedStatement, which dynamically manages array size of lastBoundChars and bindChars. So, my questions here are: Have you ever run into an issue like this? Do you know the significance of lastBoundChars / bindChars? I am new to profiling, so do you think I am not doing it correct? (I also ran the hprofs through MAT - and this was the main identified issue - so, I don't really think I could be wrong?) I have found something similar on the web here: http://forums.oracle.com/forums/thread.jspa?messageID=2860681 Appreciate your suggestions / advice.

  • Android Custom Adapter with Bar Progress

    - by xger86x
    Hi, i have a custom adapter for an arraylist. <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="horizontal"> <ProgressBar android:id="@+id/downloadprogress" style="?android:attr/progressBarStyleHorizontal" android:layout_width="200dip" android:layout_height="wrap_content" android:max="100" android:progress="50" android:secondaryProgress="75" /> <TextView android:id="@+id/tripsname" android:layout_width="wrap_content" android:layout_height="wrap_content"/> </LinearLayout> but when i try to access to the progress bar in the adapter private class MyAdapter extends ArrayAdapter<Trip> { int resource; public MyAdapter(Context context, int resource, ArrayList<Trip> items) { super(context, resource,items); this.resource=resource; } @Override public View getView(int position, View convertView, ViewGroup parent) { LinearLayout tripListItemView; final Trip t = getItem(position); String name = t.getName(); boolean offline = t.isOffline() ; if(convertView==null) { tripListItemView = new LinearLayout(getContext()); String inflater = Context.LAYOUT_INFLATER_SERVICE; LayoutInflater vi; vi = (LayoutInflater)getContext().getSystemService(inflater); vi.inflate(resource, tripListItemView, true); } else { tripListItemView = (LinearLayout) convertView; } setProgressBarVisibility(true); View v = findViewById(R.id.downloadprogress); ProgressBar progressHorizontal = (ProgressBar) findViewById(R.id.downloadprogress); it always return null, like it doesn't find the progress bar. However, the progress bar is shown in the list, but i need to access to it inside the adapter. Anybody knows the solution? Thanks

  • BlazeDS StreamingAMF: How to detect when flex client closes the connection?

    - by Adrian Pirvulescu
    Hello, I have a Flex application that connects to a BlazeDS server using the StreamingAMF channel. On the server-side the logic is handled by a custom adapter that extends ActionScriptAdapter and implements FlexSessionListener and FlexClientListener interfaces. I am asking how can I detect which "flex-client" has closed a connection when for example the user is closing the browser? (so I can clean some infos inside the database) I tried using the following: 1. To manually manage the command messages: @Override public Object manage(final CommandMessage commandMessage) { switch (commandMessage.getOperation()) { case CommandMessage.SUBSCRIBE_OPERATION: System.out.println("SUBSCRIBE_OPERATION = " + commandMessage.getHeaders()); break; case CommandMessage.UNSUBSCRIBE_OPERATION: System.out.println("UNSUBSCRIBE_OPERATION = " + commandMessage.getHeaders()); break; } return super.manage(commandMessage); } But the clientID's are always different from the ones that came. 2. Listening for sessionDestroyed and clientDestroyed events @Override public void clientCreated(final FlexClient client) { client.addClientDestroyedListener(this); System.out.println("clientCreated = " + client.getId()); } @Override public void clientDestroyed(final FlexClient client) { System.out.println("clientDestroyed = " + client.getId()); } @Override public void sessionCreated(final FlexSession session) { System.out.println("sessionCreated = " + session.getId()); session.addSessionDestroyedListener(this); } @Override public void sessionDestroyed(final FlexSession session) { System.out.println("sessionDestroyed = " + session.getId()); } But those sessionDestroyed and clientDestroyed methods are never called. :(

  • Help to understand the issue with protected method

    - by zeroed
    I'm reading Sybex Complete Java 2 Certification Study Guide April 2005 (ISBN0782144195). This book is for java developers who wants to pass java certification. After a chapter about access modifiers (along with other modifiers) I found the following question (#17): True or false: If class Y extends class X, the two classes are in different packages, and class X has a protected method called abby(), then any instance of Y may call the abby() method of any other instance of Y. This question confused me a little. As far as I know you can call protected method on any variable of the same class (or subclasses). You cannot call it on variables, that higher in the hierarchy than you (e.g. interfaces that you implement). For example, you cannot clone any object just because you inherit it. But the questions says nothing about variable type, only about instance type. I was confused a little and answered "true". The answer in the book is False. An object that inherits a protected method from a superclass in a different package may call that method on itself but not on other instances of the same class. There is nothing here about variable type, only about instance type. This is very strange, I do not understand it. Can anybody explain what is going on here?

  • Using a Scala symbol literal results in NoSuchMethod

    - by Benson
    I have recently begun using Scala. I've written a DSL in it which can be used to describe a processing pipeline in medici. In my DSL, I've made use of symbols to signify an anchor, which can be used to put a fork (or a tee, if you prefer) in the pipeline. Here's a small sample program that runs correctly: object Test extends PipelineBuilder { connector("TCP") / Map("tcpProtocol" -> new DirectProtocol()) "tcp://localhost:4858" --> "ByteToStringProcessor" --> Symbol("hello") "stdio://in?promptMessage=enter name:%20" --> Symbol("hello") Symbol("hello") --> "SayHello" / Map("prefix" -> "\n\t") --> "stdio://out" } For some reason, when I use a symbol literal in my program, I get a NoSuchMethod exception at runtime: java.lang.NoSuchMethodError: scala.Symbol.intern()Lscala/Symbol; at gov.pnnl.mif.scaladsl.Test$.<init>(Test.scala:7) at gov.pnnl.mif.scaladsl.Test$.<clinit>(Test.scala) at gov.pnnl.mif.scaladsl.Test.main(Test.scala) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at scala.tools.nsc.ObjectRunner$$anonfun$run$1.apply(ObjectRunner.scala:75) at scala.tools.nsc.ObjectRunner$.withContextClassLoader(ObjectRunner.scala:49) at scala.tools.nsc.ObjectRunner$.run(ObjectRunner.scala:74) at scala.tools.nsc.MainGenericRunner$.main(MainGenericRunner.scala:154) at scala.tools.nsc.MainGenericRunner.main(MainGenericRunner.scala) This happens regardless of how the symbol is used. Specifically, I've tried using the symbol in the pipeline, and in a simple println('foo) statement. The question: What could possibly cause a symbol literal's mere existence to cause a NoSuchMethodError? In my DSL I am using an implicit function which converts symbols to instances of the Anchor class, like so: implicit def makeAnchor(a: Symbol):Anchor = anchor(a) Sadly, my understanding of Scala is weak enough that I can't think of why that might be causing my NoSuchMethodError.

    Hi I came from the Spring camp , I don't want to use Spring , and am migrating to JavaEE6 , But I have problem testing DAO + JPA , here is my simplified sample : public interface PersonDao { public Person get(long id); } This is a very basic DAO , because I came from Spring , I believe DAO still have it value , so I decided to add a DAO layer . public class PersonDaoImpl implements PersonDao , Serializable { @PersistenceContext(unitName = "test", type = PersistenceContextType.EXTENDED) EntityManager entityManager ; public PersonDaoImpl() { } @Override public Person get(long id) { return entityManager .find(Person.class , id); } } This is a JPA-implemented DAO , I hope the EE container or the test container able to inject the EntityManager. public class PersonDaoImplTest extends TestCase { @Inject protected PersonDao personDao; @Override protected void setUp() throws Exception { //personDao = new PersonDaoImpl(); } public void testGet() { System.out.println("personDao = " + personDao); // NULL ! Person p = personDao.get(1L); System.out.println("p = " + p); } } This is my test file . OK , here comes the problem : Because JUnit doesn't understand @javax.inject.Inject , the PersonDao will not be able to injected , the test will fail. How do I find a test framework that able to inject the EntityManager to the PersonDaoImpl , and @Inject the PersonDaoImpl to the PersonDao of TestCase ? I tried unitils.org , but cannot find a sample like this , it just directly inject the EntityManagerFactory to the TestCast , not what I want ...

  • Android beginner: understanding MotionEvent actions

    - by Dave
    I am having trouble getting my activity to return a MotionEvent.ACTION_UP. Probably a beginner's error. In LogCat, I'm only seeing the ACTION_MOVE event (which is an int value of 3). I also see the X/Y coordinates. No ACTION_DOWN and no ACTION_UP. I looked everywhere for a solution. I found one question on a forum that seems to be the same as my issue, but no solution is proposed: http://groups.google.com/group/android-developers/browse_thread/thread/9a9c23e40f02c134/bf12b89561f204ad?lnk=gst&q=ACTION_UP#bf12b89561f204ad Here's my code: import android.app.Activity; import android.os.Bundle; import android.util.Log; import android.view.MotionEvent; import android.webkit.WebView; public class Brand extends Activity { public WebView webview; public float currentXPosition; public float currentYPosition; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); webview = new WebView(this); setContentView(webview); webview.loadUrl("file:///android_asset/Brand.html"); } @Override public boolean onTouchEvent(MotionEvent me) { int action = me.getAction(); currentXPosition = me.getX(); currentYPosition = me.getY(); Log.v("MotionEvent", "Action = " + action); Log.v("MotionEvent", "X = " + currentXPosition + "Y = " + currentYPosition); if (action == MotionEvent.ACTION_MOVE) { // do something } if (action == MotionEvent.ACTION_UP) { // do something } return true; } }
