• Ubuntu 12.10 no network and no graphics

  - by khasiKoMasu

  I recently upgraded Ubuntu 12.04 to 12.10 only to find out that it won't connect to any network, neither wired nor wireless and the graphics is messed up too as in a low screen resolution. For 12.04, my system was running perfectly. I don't know why upgrade messed it up so bad. Reinstalling the OS is an issue because I have set up a lot of development environments that I cannot afford to set it up again. Some of the outputs: lspci -nn | grep 0200 02:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd.

• Concurrent Affairs

  - by Tony Davis

  I once wrote an editorial, multi-core mania, on the conundrum of ever-increasing numbers of processor cores, but without the concurrent programming techniques to get anywhere near exploiting their performance potential. I came to the.controversial.conclusion that, while the problem loomed for all procedural languages, it was not a big issue for the vast majority of programmers. Two years later, I still think most programmers don't concern themselves overly with this issue, but I do think that's a bigger problem than I originally implied. Firstly, is the performance boost from writing code that can fully exploit all available cores worth the cost of the additional programming complexity? Right now, with quad-core processors that, at best, can make our programs four times faster, the answer is still no for many applications. But what happens in a few years, as the number of cores grows to 100 or even 1000? At this point, it becomes very hard to ignore the potential gains from exploiting concurrency. Possibly, I was optimistic to assume that, by the time we have 100-core processors, and most applications really needed to exploit them, some technology would be around to allow us to do so with relative ease. The ideal solution would be one that allows programmers to forget about the problem, in much the same way that garbage collection removed the need to worry too much about memory allocation. From all I can find on the topic, though, there is only a remote likelihood that we'll ever have a compiler that takes a program written in a single-threaded style and "auto-magically" converts it into an efficient, correct, multi-threaded program. At the same time, it seems clear that what is currently the most common solution, multi-threaded programming with shared memory, is unsustainable. As soon as a piece of state can be changed by a different thread of execution, the potential number of execution paths through your program grows exponentially with the number of threads. If you have two threads, each executing n instructions, then there are 2^n possible "interleavings" of those instructions. Of course, many of those interleavings will have identical behavior, but several won't. Not only does this make understanding how a program works an order of magnitude harder, but it will also result in irreproducible, non-deterministic, bugs. And of course, the problem will be many times worse when you have a hundred or a thousand threads. So what is the answer? All of the possible alternatives require a change in the way we write programs and, currently, seem to be plagued by performance issues. Software transactional memory (STM) applies the ideas of database transactions, and optimistic concurrency control, to memory. However, working out how to break down your program into sufficiently small transactions, so as to avoid contention issues, isn't easy. Another approach is concurrency with actors, where instead of having threads share memory, each thread runs in complete isolation, and communicates with others by passing messages. It simplifies concurrent programs but still has performance issues, if the threads need to operate on the same large piece of data. There are doubtless other possible solutions that I haven't mentioned, and I would love to know to what extent you, as a developer, are considering the problem of multi-core concurrency, what solution you currently favor, and why. Cheers, Tony.

• Is this spaghetti code already? [migrated]

  - by hephestos

  I post the following code writen all by hand. Why I have the feeling that it is a western spaghetti on its own. Second, could that be written better? <div id="form-board" class="notice" style="height: 200px; min-height: 109px; width: auto;display: none;"> <script type="text/javascript"> jQuery(document).ready(function(){ $(".form-button-slide").click(function(){ $( "#form-board" ).dialog(); return false; }); }); </script> <?php echo $this->Form->create('mysubmit'); echo $this->Form->input('inputs', array('type' => 'select', 'id' => 'inputs', 'options' => $inputs)); echo $this->Form->input('Fields', array('type' => 'select', 'id' => 'fields', 'empty' => '-- Pick a state first --')); echo $this->Form->input('inputs2', array('type' => 'select', 'id' => 'inputs2', 'options' => $inputs2)); echo $this->Form->input('Fields2', array('type' => 'select', 'id' => 'fields2', 'empty' => '-- Pick a state first --')); echo $this->Form->end("Submit"); ?> </div> <div style="width:100%"></div> <div class="form-button-slide" style="float:left;display:block;"> <?php echo $this->Html->link("Error Results", "#"); ?> </div> <script type="text/javascript"> jQuery(document).ready(function(){ $("#mysubmitIndexForm").submit(function() { // we want to store the values from the form input box, then send via ajax below jQuery.post("Staffs/view", { data1: $("#inputs").attr('value'), data2:$("#inputs2").attr('value'),data3:$("#fields").attr('value'), data4:$("#fields2").attr('value') } ); //Close the dialog $( "#form-board" ).dialog('close') return false; }); $("#inputs").change(function() { // we want to store the values from the form input box, then send via ajax below var input_id = $('#inputs').attr('value'); $.ajax({ type: "POST", //The controller who listens to our request url: "Inputs/getFieldsFromOneInput/"+input_id, data: "input_id="+ input_id, //+"&amp; lname="+ lname, success: function(data){//function on success with returned data $('form#mysubmit').hide(function(){}); data = $.parseJSON(data); var sel = $("#fields"); sel.empty(); for (var i=0; i<data.length; i++) { sel.append('<option value="' + data[i].id + '">' + data[i].name + '</option>'); } } }); return false; }); $("#inputs2").change(function() { // we want to store the values from the form input box, then send via ajax below var input_id = $('#inputs2').attr('value'); $.ajax({ type: "POST", //The controller who listens to our request url: "Inputs/getFieldsFromOneInput/"+input_id, data: "input_id="+ input_id, //+"&amp; lname="+ lname, success: function(data){//function on success with returned data $('form#mysubmit').hide(function(){}); data = $.parseJSON(data); var sel = $("#fields2"); sel.empty(); for (var i=0; i<data.length; i++) { sel.append('<option value="' + data[i].id + '">' + data[i].name + '</option>'); } } }); return false; }); }); </script>

• Ext JS Tab Panel - Dynamic Tabs - Tab Exists Not Working

  - by Joey Ezekiel

  Hi Would appreciate if somebody could help me on this. I have a Tree Panel whose nodes when clicked load a tab into a tab panel. The tabs are loading alright, but my problem is duplication. I need to check if a tab exists before adding it to the tab panel. I cant seem to have this resolved and it is eating my brains. This is pretty simple and I have checked stackoverflow and the EXT JS Forums for solutions but they dont seem to work for me or I'm being blind. This is my code for the tree: var opstree = new Ext.tree.TreePanel({ renderTo: 'opstree', border:false, width: 250, height: 'auto', useArrows: false, animate: true, autoScroll: true, dataUrl: 'libs/tree-data.json', root: { nodeType: 'async', text: 'Tool Actions' }, listeners: { render: function() { this.getRootNode().expand(); } } }) opstree.on('click', function(n){ var sn = this.selModel.selNode || {}; // selNode is null on initial selection renderPage(n.id); }); function renderPage(tabId) { var TabPanel = Ext.getCmp('content-tab-panel'); var tab = TabPanel.getItem(tabId); //Ext.MessageBox.alert('TabGet',tab); if(tab){ TabPanel.setActiveTab(tabId); } else{ TabPanel.add({ title: tabId, html: 'Tab Body ' + (tabId) + '', closable:true }).show(); TabPanel.doLayout(); } } }); and this is the code for the Tab Panel new Ext.TabPanel({ id:'content-tab-panel', region: 'center', deferredRender: false, enableTabScroll:true, activeTab: 0, items: [{ contentEl: 'about', title: 'About the Billing Ops Application', closable: true, autoScroll: true, margins: '0 0 0 0' },{ contentEl: 'welcomescreen', title: 'PBRT Application Home', closable: false, autoScroll: true, margins: '0 0 0 0' }] }) Can somebody please help?

• WPF MVVM ComboBox SelectedItem or SelectedValue not working

  - by cjibo

  Update After a bit of investigating. What seems to be the issue is that the SelectedValue/SelectedItem is occurring before the Item source is finished loading. If I sit in a break point and weight a few seconds it works as expected. Don't know how I'm going to get around this one. End Update I have an application using in WPF using MVVM with a ComboBox. Below is the ViewModel Example. The issue I'm having is when we leave our page and migrate back the ComboBox is not selecting the current Value that is selected. View Model public class MyViewModel { private MyObject _selectedObject; private Collection<Object2> _objects; private IModel _model; public MyViewModel(IModel model) { _model = model; _objects = _model.GetObjects(); } public Collection<MyObject> Objects { get { return _objects; } private set { _objects = value; } } public MyObject SelectedObject { get { return _selectedObject; } set { _selectedObject = value; } } } For the sake of this example lets say MyObject has two properties (Text and Id). My XAML for the ComboBox looks like this. XAML <ComboBox Name="MyComboBox" Height="23" Width="auto" SelectedItem="{Binding Path=SelectedObject,Mode=TwoWay}" ItemsSource="{Binding Objects}" DisplayMemberPath="Text" SelectedValuePath="Id"> No matter which way I configure this when I come back to the page and the object is reassembled the ComboBox will not select the value. The object is returning the correct object via the get in the property though. I'm not sure if this is just an issue with the way the ComboBox and MVVM pattern works. The text box binding we are doing works correctly.

• Why LINQ to Entities won't let me initialize just some properties of an Entity?

  - by emzero

  So I've started to add Entity Framework 4 into a legacy web application (ASP.NET WebForms). As a start I have auto-generated some entities from the database. Also I want to apply Repository Pattern. There is an entity called Visitor and its repository VisitorRepository In VisitorRepository I have the following method: public IEnumerable<Visitor> GetActiveVisitors() { var visitors = from v in _context.Visitors where v.IsActive select new Visitor { VisitorID = v.VisitorID, EmailAddress = v.EmailAddress, RegisterDate = v.RegisterDate, Company = v.Company, Position = v.Position, FirstName = v.FirstName, LastName = v.LastName }; return visitors.ToList(); } That List is then bound to a repeater and when trying to do <%# Eval('EmailAddress') #%> it throws the following exception. The entity or complex type 'Model.Visitor' cannot be constructed in a LINQ to Entities query. A) Why is this happening? How I can workaround this? Do I need to select an anonymous type and then use that to initialize my entities??? B) Why every example I've seen makes use of 'select new' (anonymous object) instead of initializing a known type? Anonymous types are useless unless you are retrieving the data and showing it in the same layer. As far as I know anonymous types cannot be returned from methods? So what's the real point of them??? Thank you all

• Overlay WPF controls

  - by sandy

  Hello I've written an 'auto-suggest' textbox user control in WPF. It behaves a little bit like the 'To' list in Hotmail, allowing the user to enter a list of items, offering suggestions when it is able. The main controls are a a text box, a wrap panel and a list box. The text box captures user input. The wrap panel contains the text box and shows previous entries. The list box is used to show suggestions. Most of the time, the list box is hidden. I'm using multiple instances of my control in a stack panel. My problem is that when the list box is shown, it is included in the measurement of the height of the control. This forces the following controls in the stack panel to be shifted down, as these pictures demonstrate: I've tried overriding the measurement of my control so not to include the list box, but this just results in the list box not being visible. What I want to do is make the list box overlay any subsequent controls in the stack panel, like a combo box's drop down would do. However, I really don't know how to do this. Any ideas? Thanks Sandy

• Why can't I resolve ambiguity with Android.OS.Environment?

  - by C. Lang

  I'm trying to use Environment.(...) in my Xamarin app. It complains that "Environment is an ambiguous reference between System.Environment and Android.OS.Environment" I can fix it by using the fully qualified name System.Environment.(...) but not with Android.OS.Environment.(...). For example: // Obviously ambiguous with error above using System; using Android.OS; // ... // OnCreate uses Bundle also in Android.OS //... string path = Environment.GetFolderPath(Environment.SpecialFolder.Personal); // Can be fixed by prefixing Environment with "System." But I can't fix it with any variation of possibilities using Android.OS including removing it and explicitly using it. The auto-complete box only shows the Activities and "Resource" and not any of the classes. // Solution to be able to use Android's Environment using Android.OS; // same as above Java.IO.File storageDir = Environment.ExternalStorageDirectory; // Defaults to Android.OS but can still use "System.Environment.(...) // Of course not with this example, but with the one above; yes. // Why doesn't it work both ways? If I remove the using statement and // try to use Android.OS.Environment.(...) it complains // 'OS type or namespace doesn't not exist' The reason is prefixing with Android. is referring to MyAppName.App.Android. Why is that and is there a way to directly access Android.OS.(...)? I've tried Mono.Android.OS.(...).

• Wicket, Spring and Hibernate - Testing with Unitils - Error: Table not found in statement [select re

  - by John

  Hi there. I've been following a tutorial and a sample application, namely 5 Days of Wicket - Writing the tests: http://www.mysticcoders.com/blog/2009/03/10/5-days-of-wicket-writing-the-tests/ I've set up my own little project with a simple shoutbox that saves messages to a database. I then wanted to set up a couple of tests that would make sure that if a message is stored in the database, the retrieved object would contain the exact same data. Upon running mvn test all my tests fail. The exception has been pasted in the first code box underneath. I've noticed that even though my unitils.properties says to use the 'hdqldb'-dialect, this message is still output in the console window when starting the tests: INFO - Dialect - Using dialect: org.hibernate.dialect.PostgreSQLDialect. I've added the entire dump from the console as well at the bottom of this post (which goes on for miles and miles :-)). Upon running mvn test all my tests fail, and the exception is: Caused by: java.sql.SQLException: Table not found in statement [select relname from pg_class] at org.hsqldb.jdbc.Util.sqlException(Unknown Source) at org.hsqldb.jdbc.jdbcStatement.fetchResult(Unknown Source) at org.hsqldb.jdbc.jdbcStatement.executeQuery(Unknown Source) at org.apache.commons.dbcp.DelegatingStatement.executeQuery(DelegatingStatement.java:188) at org.hibernate.tool.hbm2ddl.DatabaseMetadata.initSequences(DatabaseMetadata.java:151) at org.hibernate.tool.hbm2ddl.DatabaseMetadata.(DatabaseMetadata.java:69) at org.hibernate.tool.hbm2ddl.DatabaseMetadata.(DatabaseMetadata.java:62) at org.springframework.orm.hibernate3.LocalSessionFactoryBean$3.doInHibernate(LocalSessionFactoryBean.java:958) at org.springframework.orm.hibernate3.HibernateTemplate.doExecute(HibernateTemplate.java:419) ... 49 more I've set up my unitils.properties file like so: database.driverClassName=org.hsqldb.jdbcDriver database.url=jdbc:hsqldb:mem:PUBLIC database.userName=sa database.password= database.dialect=hsqldb database.schemaNames=PUBLIC My abstract IntegrationTest class: @SpringApplicationContext({"/com/upbeat/shoutbox/spring/applicationContext.xml", "applicationContext-test.xml"}) public abstract class AbstractIntegrationTest extends UnitilsJUnit4 { private ApplicationContext applicationContext; } applicationContext-test.xml: <?xml version="1.0" encoding="UTF-8"? <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd" <bean id="dataSource" class="org.unitils.database.UnitilsDataSourceFactoryBean"/ </beans and finally, one of the test classes: package com.upbeat.shoutbox.web; import org.apache.wicket.spring.injection.annot.test.AnnotApplicationContextMock; import org.apache.wicket.util.tester.WicketTester; import org.junit.Before; import org.junit.Test; import org.unitils.spring.annotation.SpringBeanByType; import com.upbeat.shoutbox.HomePage; import com.upbeat.shoutbox.integrations.AbstractIntegrationTest; import com.upbeat.shoutbox.persistence.ShoutItemDao; import com.upbeat.shoutbox.services.ShoutService; public class TestHomePage extends AbstractIntegrationTest { @SpringBeanByType private ShoutService svc; @SpringBeanByType private ShoutItemDao dao; protected WicketTester tester; @Before public void setUp() { AnnotApplicationContextMock appctx = new AnnotApplicationContextMock(); appctx.putBean("shoutItemDao", dao); appctx.putBean("shoutService", svc); tester = new WicketTester(); } @Test public void testRenderMyPage() { //start and render the test page tester.startPage(HomePage.class); //assert rendered page class tester.assertRenderedPage(HomePage.class); //assert rendered label component tester.assertLabel("message", "If you see this message wicket is properly configured and running"); } } Dump from console when running mvn test: [INFO] Scanning for projects...

• CSS overflow: hidden; does not work

  - by kapil.israni

  Hi - I am having issues with overflow: hidden not working in my case. I have a div id=ticker which basically works like a scrolling ticker. something like this - http://www.tinymassive.com/ (whats happening section). So i am prepending dynamic content to div id=ticker The div id=ticker is contained in another div which is contained in another div, basically think of it like 4-5 level tree like structure body - div[id=wrapper] - div[class=main] - div[class=content] - div[class=frame] - div[class=bg] - div[class=primary-content] - div[id=ticker] Heres the css... #wrapper { width: 942px; margin: 0 auto; position:relative; overflow:hidden; } .main{ width:942px; margin:163px 0 0; overflow:hidden; } .content{ background:url(../images/content-bg.gif) repeat-y; overflow:hidden; width:662px; float:left; } .frame{ background:url(../images/frame-bg.gif) no-repeat 0 0; width:662px; } .bg{ background:url(../images/bg-bg.gif) no-repeat 0 100%; width:662px; overflow:hidden; } .primary-content{ padding: 12px 20px 40px 22px; width:620px; overflow:hidden; } #ticker { overflow: hidden; } Also if it helps - the ticker div contains a list of div[class=breadcrumps], which i am trying to scroll .breadcrumbs{ border-bottom:1px solid #ebebeb; padding:6px 0 6px 0; overflow:hidden; clear:both; } What i see is - when i prepend breadcrumps div to ticker, the page/ticker list keeps getting bigger :( Any help would be appreciated. Thanks.

• uploadify scriptData problem

  - by elpaso66

  Hi, I'm having problems with scriptData on uploadify, I'm pretty sure the config syntax is fine but whatever I do, scriptData is not passed to the upload script. I tested in both FF and Chrome with flash v. Shockwave Flash 9.0 r31 This is the config: $(document).ready(function() { $('#id_file').uploadify({ 'uploader' : '/media/filebrowser/uploadify/uploadify.swf', 'script' : '/admin/filebrowser/upload_file/', 'scriptData' : {'session_key': 'e1b552afde044bdd188ad51af40cfa8e'}, 'checkScript' : '/admin/filebrowser/check_file/', 'cancelImg' : '/media/filebrowser/uploadify/cancel.png', 'auto' : false, 'folder' : '', 'multi' : true, 'fileDesc' : '*.html;*.py;*.js;*.css;*.jpg;*.jpeg;*.gif;*.png;*.tif;*.tiff;*.mp3;*.mp4;*.wav;*.aiff;*.midi;*.m4p;*.mov;*.wmv;*.mpeg;*.mpg;*.avi;*.rm;*.pdf;*.doc;*.rtf;*.txt;*.xls;*.csv;', 'fileExt' : '*.html;*.py;*.js;*.css;*.jpg;*.jpeg;*.gif;*.png;*.tif;*.tiff;*.mp3;*.mp4;*.wav;*.aiff;*.midi;*.m4p;*.mov;*.wmv;*.mpeg;*.mpg;*.avi;*.rm;*.pdf;*.doc;*.rtf;*.txt;*.xls;*.csv;', 'sizeLimit' : 10485760, 'scriptAccess' : 'sameDomain', 'queueSizeLimit' : 50, 'simUploadLimit' : 1, 'width' : 300, 'height' : 30, 'hideButton' : false, 'wmode' : 'transparent', translations : { browseButton: 'BROWSE', error: 'An Error occured', completed: 'Completed', replaceFile: 'Do you want to replace the file', unitKb: 'KB', unitMb: 'MB' } }); $('input:submit').click(function(){ $('#id_file').uploadifyUpload(); return false; }); }); I checked that other values (file name) are passed correctly but session_key is not. This is the decorator code from django-filebrowser, you can see it checks for request.POST.get('session_key'), the problem is that request.POST is empty. def flash_login_required(function): """ Decorator to recognize a user by its session. Used for Flash-Uploading. """ def decorator(request, *args, **kwargs): try: engine = __import__(settings.SESSION_ENGINE, {}, {}, ['']) except: import django.contrib.sessions.backends.db engine = django.contrib.sessions.backends.db print request.POST session_data = engine.SessionStore(request.POST.get('session_key')) user_id = session_data['_auth_user_id'] # will return 404 if the session ID does not resolve to a valid user request.user = get_object_or_404(User, pk=user_id) return function(request, *args, **kwargs) return decorator

• Cocoa equivalent of the Carbon method getPtrSize

  - by Michael Minerva

  I need to translate the a carbon method into cocoa into and I am having trouble finding any documentation about what the carbon method getPtrSize really does. From the code I am translating it seems that it returns the byte representation of an image but that doesn't really match up with the name. Could someone give me a good explanation of this method or link me to some documentation that describes it. The code I am translating is in a common lisp implementation called MCL that has a bridge to carbon (I am translating into CCL which is a common lisp implementation with a Cocoa bridge). Here is the MCL code (#_before a method call means that it is a carbon method): (defmethod COPY-CONTENT-INTO ((Source inflatable-icon) (Destination inflatable-icon)) ;; check for size compatibility to avoid disaster (unless (and (= (rows Source) (rows Destination)) (= (columns Source) (columns Destination)) (= (#_getPtrSize (image Source)) (#_getPtrSize (image Destination)))) (error "cannot copy content of source into destination inflatable icon: incompatible sizes")) ;; given that they are the same size only copy content (setf (is-upright Destination) (is-upright Source)) (setf (height Destination) (height Source)) (setf (dz Destination) (dz Source)) (setf (surfaces Destination) (surfaces Source)) (setf (distance Destination) (distance Source)) ;; arrays (noise-map Source) ;; accessor makes array if needed (noise-map Destination) ;; ;; accessor makes array if needed (dotimes (Row (rows Source)) (dotimes (Column (columns Source)) (setf (aref (noise-map Destination) Row Column) (aref (noise-map Source) Row Column)) (setf (aref (altitudes Destination) Row Column) (aref (altitudes Source) Row Column)))) (setf (connectors Destination) (mapcar #'copy-instance (connectors Source))) (setf (visible-alpha-threshold Destination) (visible-alpha-threshold Source)) ;; copy Image: slow byte copy (dotimes (I (#_getPtrSize (image Source))) (%put-byte (image Destination) (%get-byte (image Source) i) i)) ;; flat texture optimization: do not copy texture-id -> destination should get its own texture id from OpenGL (setf (is-flat Destination) (is-flat Source)) ;; do not compile flat textures: the display list overhead slows things down by about 2x (setf (auto-compile Destination) (not (is-flat Source))) ;; to make change visible we have to reset the compiled flag (setf (is-compiled Destination) nil))

• How to bind collection to WPF:DataGridComboBoxColumn

  - by everwicked

  Admittedly I am new to WPF but I have looked and looked and can't find a solution to this problem. I have a simple object like: class Item { .... public String Measure { get; set; } public String[] Measures {get; } } Which I am trying to bind to a DataGrid with two text columns and a combo box column. For the combo box column, propery Measure is the current selection and Measures the possible values. My XAML is: <DataGridComboBoxColumn Header="Measure" Width="Auto" SelectedItemBinding="{Binding Path=Measure}" ItemsSource="{Binding Path=Measures}"/> </DataGrid.Columns> </DataGrid> The text column are displayed just fine but the combobox is not - the values are not displayed at all. The binding error is : ¨System.Windows.Data Error: 2 : Cannot find governing FrameworkElement or FrameworkContentElement for target element. BindingExpression:Path=Measures; DataItem=null; target element is 'DataGridComboBoxColumn' (HashCode=11497055); target property is 'ItemsSource' (type 'IEnumerable') How do I fix this??? Thanks

• How do I set the timeout for a JAX-WS webservice client?

  - by ninesided

  I've used JAXWS-RI 2.1 to create an interface for my web service, based on a WSDL. I can interact with the web service no problems, but haven't been able to specify a timeout for sending requests to the web service. If for some reason it does not respond the client just seems to spin it's wheels forever. Hunting around has revealed that I should probably be trying to do something like this: ((BindingProvider)myInterface).getRequestContext().put("com.sun.xml.ws.request.timeout", 10000); ((BindingProvider)myInterface).getRequestContext().put("com.sun.xml.ws.connect.timeout", 10000); I also discovered that, depending on which version of JAXWS-RI you have, you may need to set these properties instead: ((BindingProvider)myInterface).getRequestContext().put("com.sun.xml.internal.ws.request.timeout", 10000); ((BindingProvider)myInterface).getRequestContext().put("com.sun.xml.internal.ws.connect.timeout", 10000); The problem I have is that, regardless of which of the above is correct, I don't know where I can do this. All I've got is a Service subclass that implements the auto-generated interface to the webservice and at the point that this is getting instanciated, if the WSDL is non-responsive then it's already too late to set the properties: MyWebServiceSoap soap; MyWebService service = new MyWebService("http://www.google.com"); soap = service.getMyWebServiceSoap(); soap.sendRequestToMyWebService(); Can anyone point me in the right direction?!

• axis2 web service behave differently when tested with web service client or with local test class

  - by Stefano

  Hello I need to update a facade to some web service proxy classes to a third party web service, and expose them as a service. This for two reason : to maintain the same interface for all application that need to use the system : actually its migrating and there are a few differences in the third party ws (method names); and to expose a simplified interface. The third party has provided me with a manual and some pregenerated proxy classes to their service (the java file says generated with axis2 1,4) . I've used netbeans 6.8 and the axis2 plugin to create an axis2 service . This service contains the proxy classes and the facade class which instantiate the web service proxy and calls its method; the facade class is exposed as service. I've used axis2 1.4 (at beginnig and later 1.5 ) and tomcat 6.0. The first test i did was to call the facede methods from inside the project itself and it worked. Then i've created a new project with a jax-ws web service client to call my class deployed on axis2. At this point has happened two strange thing : In the axis2 services page has appeared the third party proxy class as if it were a new service (if i try to get the wsdl axis raises an error ). eg. the proxy interface is named WebServiceAPI (_stub is the concrete class) and , after the first call to my service , i find a new "WebServicesAPI1272968932531_1" service inside axis . The call obvoiusly fail i've began to sniff soap messages with wireshark and i've found they differs when using proxy classes direclty from my facade test class by the messages created after being deployed on axis. i've noticed they differs for the presence of the soap header in the failing message. any help would be greatly appreciated : maybe i messed up something, there might be some incompatibilities or version mistakes? below i've added the signature of the third party proxy, its impementation and the different soap messages: /* * WebServicesAPI.java * This file was auto-generated from WSDL * by the Apache Axis2 version: 1.4 Built on : Apr 26, 2008 (06:24:30 EDT) */ package com.ibm.eci.wsapi;

• NSString variable out of scope in sub-class (iPhone/Obj-C)

  - by Rich

  I am following along with an example in a book with the code exactly as it is in the example code as well as from the book, and I'm getting an error at runtime. I'll try to describe the life cycle of this variable as good as I can. I have a controller class with a nested array that is populated with string literals (NSArray of NSArrays, the nested NSArrays initialized with arrayWithObjects: where the objects are all string literals - @"some string"). I access these strings with a helper method added via a category on NSArray (to pull strings out of a nested array). My controller gets a reference to this string and assigns it to a NSString property on a child controller using dot notation. The code looks like this (nestedObjectAtIndexPath is my helper method): NSString *rowKey = [rowKeys nestedObjectAtIndexPath:indexPath]; controller.keypath = rowKey; keypath is a synthesized nonatomic, retain property defined in a based class. When I hit a breakpoint in the controller at the above code, the NSString's value is as expected. When I hit the next breakpoint inside the child controller, the object id of the keypath property is the same as before, but instead of showing me the value of the NSString, XCode says that the variable is "out of scope" which is also the error I see in the console. This also happens in another sub-class of the same parent. I tried googling, and I saw slightly similar cases where people were suggesting this had to do with retain counts. I was under the impression that by using dot notation on a synthesized property, my class would be using an "auto generated accessor" that would be increasing my retain count for me so that I wouldn't have this problem. Could there be any implications because I'm accessing it in a sub-class and the prop is defined in the parent? I don't see anything in the book's errata about this, but the book is relatively new (Apress - More iPhone 3 Dev). I also have double checked that my code matches the example 100 times.

• Autocompletebox text in Silverlight

  - by Ciaran

  I'm having trouble getting the autocomplete box in System.Windows.Controls.Input working as I wish. When I start typing the dropdown section that displays the filtered list doesn't show the property that I'm binding to, it shows the class name instead. So in the example below, when I type in my - instead of showing 'My Name' it shows MyNamespace.Person. However, when I select the item from the autocomplete list, it displays the FullName property in the textbox. I'm sure I'm just missing a simple autocomplete box property somewhere but I can't see it. Example code: public class Person { public string FirstName { get; set; } public string LastName { get; set; } public string FullName { get { return string.Format("{0} {1}", FirstName, LastName); } } } In my xaml code behind I create some Person objects and store them in a list and bind that list to an autocomplete box List<Person> people = new List<Person>(); people.Add(new Person { FirstName = "My", LastName = "Name" }); people.Add(new Person { FirstName = "Fernando", LastName = "Torres" }); acbNames.ItemsSource = people; My xaml: <my:AutoCompleteBox Name="acbNames" ValueMemberPath="FullName" /> /* after entering 'my', auto complete displays 'MyNamespace.Person' instead of 'My Name', but displays 'My Name' after selecting the item from the list */

• UIScrollView frame size issue in Landscape Mode

  - by viper15

  I'm trying to make UIScrollView auto-resize and appear correctly in Landscape mode. Portrait mode works fine. Here's my code: - (void)viewDidLoad { [super viewDidLoad]; //=== load all the custom view NSMutableArray *controllers = [[NSMutableArray alloc] init]; int page = 0; [controllers addObject:[self loadScrollView:[[Page1ViewController alloc] initWithNibName:@"Page1ViewController" bundle:nil] withPage:page++]]; [controllers addObject:[self loadScrollView:[[Page2ViewController alloc] initWithNibName:@"Page2ViewController" bundle:nil] withPage:page++]]; [controllers addObject:[self loadScrollView:[[Page3ViewController alloc] initWithNibName:@"Page3ViewController" bundle:nil] withPage:page++]]; self.viewControllers = controllers; [controllers release]; //=== automaticaly define number of pages _numberOfPages = [self.viewControllers count]; // a page is the width of the scroll view scrollView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; scrollView.pagingEnabled = YES; scrollView.contentSize = CGSizeMake(scrollView.frame.size.width * _numberOfPages, scrollView.frame.size.height); scrollView.showsHorizontalScrollIndicator = NO; scrollView.showsVerticalScrollIndicator = NO; scrollView.scrollsToTop = NO; scrollView.delegate = self; // First, set the number of pages pageControl.numberOfPages = _numberOfPages; pageControl.currentPage = 0; } Then, I went into each view controller nib file and set the background to different color to test if it's working. Unfortunately, when in Landscape mode, the width and height remains the same as in Portrait Mode. I'm not sure how to fix this problem. Hope anyone can help me. Many thanks in advance.

• jQuery UI dialog on ASP.NET page (inside user control)

  - by marc_s

  I have a really odd behavior here: I created a little popup dialog in jQuery UI, and in my test HTML page, it works flawlessly. When I click on the button, the popup comes up, covers the background, and remains on screen until I click on one of the two buttons (OK or Cancel) provided. So now I wanted to add this into my ASP.NET 3.5 app. I wanted to add it to a GridView inside a user controls (ASCX), which is on a page (ASPX) contained inside a master page. The jQuery 1.4.2 and jQuery UI 1.8.1 scripts are referenced on the master page: <body> <form id="XXXXXX" runat="server"> <Ajax:ScriptManager ID="masterScriptManager" runat="server" ScriptMode="Auto"> <Scripts> <asp:ScriptReference Path="~/Scripts/jquery-1.4.2.min.js" /> <asp:ScriptReference Path="~/Scripts/jquery-ui-1.8.1.custom.min.js" /> </Scripts> </Ajax:ScriptManager> I had to change this to use the Ajax script manager, since adding them to the as never worked. So in my gridview, I have a column with image buttons, and when the user clicks on those, I am calling a little javascript function to show the jQuery UI dialog: function showDialog() { $("#dlg-discount").dialog('open'); $("#txtAmount").focus(); } When I run this page in MS IE 8, I get a separate page, and at the top of the page, I get the contents of my , with proper background color and all. In Firefox 3.5.6, I do get the dialog as a popup. In both cases, the dialog page/popup disappears again after a second or less - without me clicking anything! It seems similar to this question but the solution provided there doesn't work in my case. This one here also seems similar but again: the solution presented doesn't seem to work in my case... Any ideas / hints / tips on what the h** is going on here?? Thanks!

• UIScrollView with pages enabled and device rotation/orientation changes (MADNESS)

  - by jbrennan

  I'm having a hard time getting this right. I've got a UIScrollView, with paging enabled. It is managed by a view controller (MainViewController) and each page is managed by a PageViewController, its view added as a subview of the scrollView at the proper offset. Scrolling is left-right, for standard orientation iPhone app. Works well. Basically exactly like the sample provided by Apple and also like the Weather app provided with the iPhone. However, when I try to support other orientations, things don't work very well. I've supported every orientation in both MainViewController and PageViewController with this method: - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } However, when I rotate the device, my pages become quite skewed, and there are lots of drawing glitches, especially if only some of the pages have been loaded, then I rotate, then scroll more, etc... Very messy. I've told my views to support auto-resizing with theView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; But to no avail. It seems to just stretch and distort my views. In my MainViewController, I added this line in an attempt to resize all my pages' views: - (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation { self.scrollView.contentSize = CGSizeMake(self.scrollView.frame.size.width * ([self.viewControllers count]), self.scrollView.frame.size.height); for (int i = 0; i < [self.viewControllers count]; i++) { PageViewController *controller = [self.viewControllers objectAtIndex:i]; if ((NSNull *)controller == [NSNull null]) continue; NSLog(@"Changing frame: %d", i); CGRect frame = self.scrollView.frame; frame.origin.x = frame.size.width * i; frame.origin.y = 0; controller.view.frame = frame; } } But it didn't help too much (because I lazily load the views, so not all of them are necessarily loaded when this executes). Is there any way to solve this problem?
