• How to handle the back button on Windows Phone 7

  - by David_001

  On the windows phone 7 emulator, when the hardware back button is pressed, the default behaviour is for it to close your current application. I want to override this default behaviour so that it navigates to the previous page in my application. After some research, it seems it should be possible to do this by overriding the OnBackKeyPress method, like so: protected override void OnBackKeyPress(System.ComponentModel.CancelEventArgs e) { // do some stuff ... // cancel the navigation e.Cancel = true; } However, clicking the back button still closes my application. Putting a breakpoint on the above method reveals that it is never called. I have another breakpoint on my application exit code, and this breakpoint is hit. Is there something else I need to do to intercept the back button?

• Java, Jacob and Microsoft Outlook events: Receiving "Can't find event iid" Error

  - by Adam Paynter

  I am writing a Java program that interacts with Microsoft Outlook using the Jacob library (bridges COM and Java). This program creates a new MailItem, displaying its Inspector window to the user. I wish to subscribe to the inspector's Close event to know when the user is finished editing their mail item. To subscribe to the event, I followed the instructions in Jacob's documentation (about 2⁄3 down the page): The current [event] model is conceptually similar to the Visual Basic WithEvents construct. Basically, I provide a class called com.jacob.com.DispatchEvents which has a constructor that takes a source object (of type com.jacob.com.Dispatch) and a target object (of any type). The source object is queried for its IConnectionPointContainer interface and I attempt to obtain an IConnectionPoint for its default source interface (which I obtain from IProvideClassInfo). At the same time, I also create a mapping of DISPID's for the default source interface to the actual method names. I then use the method names to get jmethodID handles from the target Java object. All event methods currently must have the same signature: one argument which is a Java array of Variants, and a void return type. Here is my InspectorEventHandler class, conforming to Jacob's documentation: public class InspectorEventHandler { public void Activate(Variant[] arguments) { } public void BeforeMaximize(Variant[] arguments) { } public void BeforeMinimize(Variant[] arguments) { } public void BeforeMove(Variant[] arguments) { } public void BeforeSize(Variant[] arguments) { } public void Close(Variant[] arguments) { System.out.println("Closing"); } public void Deactivate(Variant[] arguments) { } public void PageChange(Variant[] arguments) { } } And here is how I subscribe to the events using this InspectorEventHandler class: Object outlook = new ActiveXComponent("Outlook.Application"); Object mailItem = Dispatch.call(outlook, "CreateItem", 0).getDispatch(); Object inspector = Dispatch.get(mailItem, "GetInspector").getDispatch(); InspectorEventHandler eventHandler = new InspectorEventHandler(); // This supposedly registers eventHandler with the inspector new DispatchEvents((Dispatch) inspector, eventHandler); However, the last line fails with the following exception: Exception in thread "main" com.jacob.com.ComFailException: Can't find event iid at com.jacob.com.DispatchEvents.init(Native Method) at com.jacob.com.DispatchEvents.(DispatchEvents.java) at cake.CakeApplication.run(CakeApplication.java:30) at cake.CakeApplication.main(CakeApplication.java:15) couldn't get IProvideClassInfo According to Google, a few others have also received this error. Unfortunately, none of them have received an answer. I am using version 1.7 of the Jacob library, which claims to prevent this problem: Version 1.7 also includes code to read the type library directly from the progid. This makes it possible to work with all the Microsoft Office application events, as well as IE5 events. For an example see the samples/test/IETest.java example. I noticed that the aforementioned IETest.java file subscribes to events like this: new DispatchEvents((Dispatch) ieo, ieE,"InternetExplorer.Application.1"); Therefore, I tried subscribing to my events in a similar manner: new DispatchEvents((Dispatch) inspector, eventHandler, "Outlook.Application"); new DispatchEvents((Dispatch) inspector, eventHandler, "Outlook.Application.1"); new DispatchEvents((Dispatch) inspector, eventHandler, "Outlook.Application.12"); All these attempts failed with the same error.

• OAuth + Twitter on Android: Callback fails

  - by Samuh

  My Android application uses Java OAuth library, found here for authorization on Twitter. I am able to get a request token, authorize the token and get an acknowlegement but when the browser tries the call back url to reconnect with my application, it does not use the URL I provide in code, but uses the one I supplied while registering with Twitter. Note: 1. When registering my application with twitter, I provided a hypothetical call back url:http://abz.xyc.com and set the application type as browser. 2. I provided a callback url in my code "myapp" and have added an intent filter for my activity with Browsable category and data scheme as "myapp". 3. URL called when authorizing does contain te callback url, I specified in code. Any idea what I am doing wrong here? Relevant Code: public class FirstActivity extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); OAuthAccessor client = defaultClient(); Intent i = new Intent(Intent.ACTION_VIEW); i.setData(Uri.parse(client.consumer.serviceProvider.userAuthorizationURL + "?oauth_token=" + client.requestToken + "&oauth_callback=" + client.consumer.callbackURL)); startActivity(i); } OAuthServiceProvider defaultProvider() { return new OAuthServiceProvider(GeneralRuntimeConstants.request_token_URL, GeneralRuntimeConstants.authorize_url, GeneralRuntimeConstants.access_token_url); } OAuthAccessor defaultClient() { String callbackUrl = "myapp:///"; OAuthServiceProvider provider = defaultProvider(); OAuthConsumer consumer = new OAuthConsumer(callbackUrl, GeneralRuntimeConstants.consumer_key, GeneralRuntimeConstants.consumer_secret, provider); OAuthAccessor accessor = new OAuthAccessor(consumer); OAuthClient client = new OAuthClient(new HttpClient4()); try { client.getRequestToken(accessor); } catch (Exception e) { e.printStackTrace(); } return accessor; } @Override protected void onResume() { // TODO Auto-generated method stub super.onResume(); Uri uri = this.getIntent().getData(); if (uri != null) { String access_token = uri.getQueryParameter("oauth_token"); } } } // Manifest file <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".FirstActivity" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> <intent-filter> <action android:name="android.intent.action.VIEW" /> <category android:name="android.intent.category.DEFAULT" /> <category android:name="android.intent.category.BROWSABLE" /> <data android:scheme="myapp"/> </intent-filter> </activity> </application>

• OAuth Callback procedure for mobile devices

  - by behrk2

  Hello, I am designing a Netflix Application for BlackBerry mobile devices. I am currently working on the OAuth. I am at the point where I can generate a Netflix login page in an embedded browser field in my application. After the user signs in, Netflix will send the user from the login page to a specified callback url. The callback url will also contain an authorized token, which is then needed to send back to Netflix. My question is: How am I supposed to do this on a mobile device? Is there a procedure set in place? I am unsure how I can extract the authorized token from the callback URL and send it back to my application. From my research, it does not appear that Netflix will provide a PIN/verifier for the user to then type into the application... Does anyone have any ideas? Thanks...

• BlackBerry Simulator & BIS Push Service

  - by Submerged

  I am hoping that someone knows if you can use RIMM's push service with BIS WITHOUT a hand held device. I have registered for the push evaluation and I want to program a push server that will send out notifications to BB clients. I got my email this morning containing: Server: Application: XXXXXXXXXXXXXXXXXXX Pwd: xxxXXXXX CPID (Content Provider ID):xxx Start Date (MM/DD/YYYY): X/X/XXXX Expiry Date (MM/DD/YYYY):X/X/XXXX First Name:XXXXXXX Last Name:XXXXX Email:[email protected] Account Type:Plus Source IP:xxx.xxx.xxx.xxx Usage:BIS AND Client: Application Credentials (for use in your client application): Application ID:XXX-xxxxxxxxxxxxxxx Push Port:xxxxx I am hoping someone can tell me where to get started - as an iPhone developer, I have to say, there is much more information. Lastly, if I DO need a device, does that device have to have a dataplan? I wanted to be able to serve my clients from WiFi as well, does the BB push system work only on Cell networks? Thank you

• How to modify IIS handler mapping permissions via Wix or a Custom Action

  - by Finch

  Hi, I'm using Wix to create an installer for a Silverlight application. When I install the application the virtual directory that has been created has the execute permission checked for the *.dll handler mapping (IIS 7 Web site VDir Handler Mappings *.dll Edit Feature Permissions Execute). When I browse to the application it cannot download its satellite assemblies in ClientBin. If I uncheck the execute permission in IIS the handler becomes disabled and the application now works. I don't want to have to do this manually. Does anybody know how to modify the handler mapping permissions in Wix or a Custom Action? Thanks

• Windows Azure : Server Error , 404 - File or directory not found.

  - by veda

  I want to upload some files of size 35MB on to the blob container. I have coded for splitting the data into blocks and upload it on to the blob container and form a blob using PUT. I tested the code for some files of Size 2MB or something... It worked well. But When I tried it for a large MB file, its giving me this error Server Error 404 - File or directory not found. The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable. when I tried it for files of size 6MB, it gives me this error.. Server Error in '/' Application. Runtime Error Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine. Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application.

• Secondary monitor bug: a problem in WPF or in the graphics driver?

  - by emddudley

  I have discovered a strange bug with my WPF application and I am trying to determine whether it is a problem with WPF or my graphics driver so that I can report it to the appropriate company. I have a Quadro FX 1700 with the latest drivers (197.54) on a Windows XP system, running a .NET 3.5 SP1 application. I have dual monitors, and when I maximize then minimize a child window of the main window on my primary monitor, the child window gets drawn on the secondary monitor as well. It appears in both places. I made a sample application (code is below) which induces this behavior. Start the application and ensure the main window is on your primary monitor. Double-click the main window. A green child window should appear. Click the green child window to maximize. Click the green child window to minimize. Can anyone else reproduce this problem? On my system the green child restores, but then it's drawn on both my primary and secondary monitors, rather than just the primary monitor. App.xaml <Application xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Class="DualMonitorBug.App" StartupUri="Shell.xaml" /> App.xaml.cs using System.Windows; namespace DualMonitorBug { public partial class App : Application { } } Shell.xaml <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Class="DualMonitorBug.Shell" Title="Shell" Height="480" Width="640" MouseDoubleClick="ShowDialog" /> Shell.xaml.cs using System.Windows; using System.Windows.Input; namespace DualMonitorBug { public partial class Shell : Window { public Shell() { InitializeComponent(); } private void ShowDialog(object sender, MouseButtonEventArgs e) { DialogWindow dialog = new DialogWindow(); dialog.Owner = this; dialog.Show(); } } } DialogWindow.xaml <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Class="DualMonitorBug.DialogWindow" Title="Dialog Window" Height="240" Width="320" AllowsTransparency="True" Background="Green" MouseLeftButtonDown="ShowHideDialog" WindowStyle="None" /> DialogWindow.xaml.cs using System.Windows; using System.Windows.Input; namespace DualMonitorBug { public partial class DialogWindow : Window { public DialogWindow() { InitializeComponent(); } private void ShowHideDialog(object sender, MouseButtonEventArgs e) { this.WindowState = (this.WindowState == WindowState.Normal) ?

• What are the reasons why the CPU usage doesn’t go 100% with C# and APM?

  - by Martin

  I have an application which is CPU intensive. When the data is processed on a single thread, the CPU usage goes to 100% for many minutes. So the performance of the application appears to be bound by the CPU. I have multithreaded the logic of the application, which result in an increase of the overall performance. However, the CPU usage hardly goes above 30%-50%. I would expect the CPU (and the many cores) to go to 100% since I process many set of data at the same time. Below is a simplified example of the logic I use to start the threads. When I run this example, the CPU goes to 100% (on an 8/16 cores machine). However, my application which uses the same pattern doesn’t. public class DataExecutionContext { public int Counter { get; set; } // Arrays of data } static void Main(string[] args) { // Load data from the database into the context var contexts = new List<DataExecutionContext>(100); for (int i = 0; i < 100; i++) { contexts.Add(new DataExecutionContext()); } // Data loaded. Start to process. var latch = new CountdownEvent(contexts.Count); var processData = new Action<DataExecutionContext>(c => { // The thread doesn't access data from a DB, file, // network, etc. It reads and write data in RAM only // (in its context). for (int i = 0; i < 100000000; i++) c.Counter++; }); foreach (var context in contexts) { processData.BeginInvoke(context, new AsyncCallback(ar => { latch.Signal(); }), null); } latch.Wait(); } I have reduced the number of locks to the strict minimum (only the latch is locking). The best way I found was to create a context in which a thread can read/write in memory. Contexts are not shared among other threads. The threads can’t access the database, files or network. In other words, I profiled my application and I didn’t find any bottleneck. Why the CPU usage of my application doesn’t go about 50%? Is it the pattern I use? Should I create my own thread instead of using the .Net thread pool? Is there any gotchas? Is there any tool that you could recommend me to find my issue? Thanks!

• Apple Push Notification-Unable to callback didRegisterForRemoteNotificationsWithDeviceToken

  - by Shailesh Kanzariya

  I have been simply trying to get deviceToken from my iPhone application using Apple Push Notification Service. I don't have any implementation on server side for the time being. I have created APP Id, got SSL certificate, Provision Profile with APN and calling - (void)applicationDidFinishLaunching:(UIApplication *)application { //view init and add sub view to window [[UIApplication sharedApplication] registerForRemoteNotificationTypes:UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound]; } method. When I execute the application it pop ups action box to allow Push Notification (means my request for APN registration is working) but my callback is not executed. Neither didRegisterForRemoteNotificationsWithDeviceToken nor didFailToRegisterForRemoteNotificationsWithError is called? can anybody help me to resolve the issue? Following are my callbacs for reference. - (void)application:(UIApplication *)app didFailToRegisterForRemoteNotificationsWithError:(NSError *)err { UIAlertView *myAlert = [[UIAlertView alloc] initWithTitle:@"APNClient" message:@"Entered into Error Method" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; [myAlert show]; [myAlert release]; NSLog(@"Error in registration. Error: %@", err); } - (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)devToken { UIAlertView *myAlert = [[UIAlertView alloc] initWithTitle:@"APNClient" message:@"Got the deviceToken..!" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; [myAlert show]; [myAlert release]; }

• .NET Backgroundworker - Is there no way to let exceptions pass back normally to main thread?

  - by Greg

  Hi, QUESTION: Re use of .NET Backgroundworker, is there not a way to let exceptions pass back normally to main thread? BACKGROUND: Currently in my WinForms application I have generic exception handle that goes along the lines of, if (a) a custom app exception then present to user, but don't exit program, and (b) if other exception then present and then exit application The above is nice as I can just throw the appropriate exception anywhere in the application and the presentation/handling is handled generically

• Version control a content management system?

  - by Mike

  I have the following directory structure in the CMS application we have written: /application /modules /cms /filemanager /block /pages /sitemap /youtube /rss /skin /backend /default /css /js /images /frontend /default /css /js /images Application contains code specific to the current CMS implementation, i.e code for this specific cms. Modules contain reusable portions of code that we share across projects, such as libraries to work with youtube or rss feeds. We include these as git submodules, so that we can update the module in any website and push the changes back across all other projects. It makes it really easy to apply a change to our code and distribute it. We wanted to turn the CMS into a module so we get the same benefit - we can run the entire project under source control, then update the cms as required through a git-submodule. We have run into a problem however: the cms requires javascript/images/css in order for it to work correctly. Things we have thought about: We could create 2 submodules, one for cms-skin and one for cms, but this means you cannot "git pull" one version without having some idea of which versions of skin work with which versions of cms. i.e version 1.2.2 CMS might have issues with 1.0.3 CMS-Skin We could add the skin to the cms module but this has the following problems: Skin should be available on the document root, module code shouldn't be, and if it is it should probably be secured via .htaccess It doesn't seem to make any sense bundling assets with php code We could create a symlink between /skin/backend/ to go to /modules/cms/skin but does this cause any security problems, and do we want to require something like a symlink for the application to work? We could create a hook for git or a shell script that copies files from modules/cms/skin to skin/backend when an update occurs, but this means we lose the ability to edit CMS core files in a project then push them back How is this typically done in large scale cms's? How is it possible to get the source code for a cms under version control, work on the application for a client, then update the sourcecode as releases and given by the vendor? How do applications like Magento or Drupal do this?

• How to fix flicker when using Webkit transforms & transitions

  - by gargantaun

  I have a very simple demo working that uses Webkit transforms and transitions for smooth horizontal scrolling between 'panels' (divs). The reason I want to go this route as opposed to a Javascript driven system is that it's for the iPad and Javascript performance is quite poor, but the css transforms and transitions are smooth as silk. Sadly though, I'm getting a lot of flicker on the iPad with my Demo. You can see the demo here You'll need safari or and iPad to see it in action. I've never seen this happening in any of the demos for transforms and transitions so I'm hopeful that this is fixable. Anyway here's the code that powers the thing.... The HTML looks like this. <html> <head> <title>Swipe Demo</title> <link href="test.css" rel="stylesheet" /> <link href="styles.css" rel="stylesheet" /> <script type="text/javascript" src="jquery.js"></script> <script type="text/javascript" src="functions.js"></script> <script type="text/javascript" src="swiping.js"></script> </head> <body> <div id="wrapper"> <div class='panel one'> <h1>This is panel 1</h1> </div> <div class='panel two'> <h1>This is panel 2</h1> </div> <div class='panel three'> <h1>This is panel 3</h1> </div> <div class='panel four'> <h1>This is panel 4</h1> </div> </div> </body> </html> The CSS looks like this body, html { padding: 0; margin: 0; background: #000; } #wrapper { width: 10000px; -webkit-transform: translateX(0px); } .panel { width: 1024px; height: 300px; background: #fff; display: block; float: left; position: relative; } and the javascript looks like this // Mouse / iPad Touch var touchSupport = (typeof Touch == "object"), touchstart = touchSupport ? 'touchstart' : 'mousedown', touchmove = touchSupport ? 'touchmove' : 'mousemove', touchend = touchSupport ? 'touchend' : 'mouseup'; $(document).ready(function(){ // set top and left to zero $("#wrapper").css("top", 0); $("#wrapper").css("left", 0); // get total number of panels var panelTotal; $(".panel").each(function(){ panelTotal += 1 }); // Touch Start // ------------------------------------------------------------------------------------------ var touchStartX; var touchStartY; var currentX; var currentY; var shouldMove = false; document.addEventListener(touchstart, swipeStart, false); function swipeStart(event){ touch = realEventType(event); touchStartX = touch.pageX; touchStartY = touch.pageY; var pos = $("#wrapper").position(); currentX = parseInt(pos.left); currentY = parseInt(pos.top); shouldMove = true; } // Touch Move // ------------------------------------------------------------------------------------------ var touchMoveX; var touchMoveY; var distanceX; var distanceY; document.addEventListener(touchmove, swipeMove, false); function swipeMove(event){ if(shouldMove){ touch = realEventType(event); event.preventDefault(); touchMoveX = touch.pageX; touchMoveY = touch.pageY; distanceX = touchMoveX - touchStartX; distanceY = touchMoveY - touchStartY; movePanels(distanceX); } } function movePanels(distance){ newX = currentX + (distance/4); $("#wrapper").css("left", newX); } // Touch End // ------------------------------------------------------------------------------------------ var cutOff = 100; var panelIndex = 0; document.addEventListener(touchend, swipeEnd, false); function swipeEnd(event){ touch = (touchSupport) ? event.changedTouches[0] : event; var touchEndX = touch.pageX; var touchEndY = touch.pageY; updatePanelIndex(distanceX); gotToPanel(); shouldMove = false; } // -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- function updatePanelIndex(distance){ if(distanceX > cutOff) panelIndex -= 1; if(distanceX < (cutOff * -1)){ panelIndex += 1; } if(panelIndex < 0){ panelIndex = 0; } if(panelIndex >= panelTotal) panelIndex = panelTotal -1; console.log(panelIndex); } // -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- function gotToPanel(){ var panelPos = getTotalWidthOfElement($(".panel")) * panelIndex * -1; $("#wrapper").css("-webkit-transition-property", "translateX"); $("#wrapper").css("-webkit-transition-duration", "1s"); $("#wrapper").css("-webkit-transform", "translateX("+panelPos+"px)"); } }); function realEventType(event){ e = (touchSupport) ? event.targetTouches[0] : event; return e; }

• Running a Java program with a .dll from Adobe AIR's native process

  - by Donny

  I would like to be able to operate a scanner from my AIR application. Since there's no support for this natively, I'm trying to use the NativeProcess class to start a jar file that can run the scanner. The Java code is using the JTwain library to operate the scanner. The Java application runs fine by itself, and the AIR application can start and communicate with the Java application. The problem seems to be that any time I attempt to use a function from JTwain (which relies on the JTwain.dll), the application dies IF AIR STARTED IT. I'm not sure if there's some limit about referencing dll files from the native process or what. I've included my code below Java code- while(true) { try { System.out.println("Start"); text = in.readLine(); Source source = SourceManager.instance().getCurrentSource(); System.out.println("Java says: "+ text); } catch (IOException e) { System.err.println("Exception while reading the input. " + e); } catch (Exception e) { System.out.println("Other exception occured: " + e.toString()); } finally { } } } Air application- import mx.events.FlexEvent; private var nativeProcess:NativeProcess; private var npInfo:NativeProcessStartupInfo; private var processBuffer:ByteArray; private var bLength:int = 0; protected function windowedapplication1_applicationCompleteHandler(event:FlexEvent):void { var arg:Vector.<String> = new Vector.<String>; arg.push("-jar"); arg.push(File.applicationDirectory.resolvePath("Hello2.jar").nativePath); processBuffer = new ByteArray; npInfo = new NativeProcessStartupInfo; npInfo.executable = new File("C:/Program Files/Java/jre6/bin/javaw.exe"); npInfo.arguments = arg; nativeProcess = new NativeProcess; nativeProcess.addEventListener(ProgressEvent.STANDARD_OUTPUT_DATA, onStandardOutputData); nativeProcess.start(npInfo); } private function onStandardOutputData(e:ProgressEvent):void { tArea.text += nativeProcess.standardOutput.readUTFBytes(nativeProcess.standardOutput.bytesAvailable); } protected function button1_clickHandler(event:MouseEvent):void { tArea.text += 'AIR app: '+tInput.text + '\n'; nativeProcess.standardInput.writeMultiByte(tInput.text + "\n", 'utf-8'); tInput.text = ''; } protected function windowedapplication1_closeHandler(event:Event):void { nativeProcess.closeInput(); } ]]> </fx:Script> <s:Button label="Send" x="221" y="11" click="button1_clickHandler(event)"/> <s:TextInput id="tInput" x="10" y="10" width="203"/> <s:TextArea id="tArea" x="10" width="282" height="88" top="40"/> I would love some explanation about why this is dying.

When the application is started, the user is prompted to authenticate into the database. I have another computer set up within the same domain that has Access 2007 installed on it. I log in using the same credentials that I use to get on the machine that has Access 2003. I converted my application to Access 2007 format and everything works fine. However, when other users try to use the application, they are prompted to enter the database password every time a table is accessed. Thinking it was a problem with my ODBC, I confirmed that the connections were set up the same way on both of my machines, and the user's machine. Here is the interesting part, when the user logged into my machine, it started prompting for the password every time. When I logged into the user's machine, the application worked fine. Anyone have any ideas? All help is appreciated!

• JSF: Cannot catch ViewExpiredException

  - by ifischer

  I'm developing a JSF 2.0 application on Glassfish v3 and i'm trying to handle the ViewExpiredException. But whatever i do, i always get a Glassfish error report instead of my own error page. To simulate the occurrence of the VEE, i inserted the following function into my backing bean, which fires the VEE. I'm triggering this function from my JSF page through a commandLink. The Code: @Named public class PersonHome { (...) public void throwVEE() { throw new ViewExpiredException(); } } At first i tried it by simply adding an error-page to my web.xml: <error-page> <exception-type>javax.faces.application.ViewExpiredException</exception-type> <location>/error.xhtml</location> </error-page> But this doesn't work, i'm not redirected to error but i'm shown the Glassfish errorpage, which shows a HTTP Status 500 page with the following content: description:The server encountered an internal error () that prevented it from fulfilling this request. exception: javax.servlet.ServletException: javax.faces.application.ViewExpiredException root cause: javax.faces.el.EvaluationException:javax.faces.application.ViewExpiredException root cause:javax.faces.application.ViewExpiredException Next thing i tried was to write ExceptionHandlerFactory and a CustomExceptionHandler, as described in JavaServerFaces 2.0 - The Complete Reference. So i inserted the following tag into faces-config.xml: <factory> <exception-handler-factory> exceptions.ExceptionHandlerFactory </exception-handler-factory> </factory> And added these classes: The factory: package exceptions; import javax.faces.context.ExceptionHandler; public class ExceptionHandlerFactory extends javax.faces.context.ExceptionHandlerFactory { private javax.faces.context.ExceptionHandlerFactory parent; public ExceptionHandlerFactory(javax.faces.context.ExceptionHandlerFactory parent) { this.parent = parent; } @Override public ExceptionHandler getExceptionHandler() { ExceptionHandler result = parent.getExceptionHandler(); result = new CustomExceptionHandler(result); return result; } } The custom exception handler: package exceptions; import java.util.Iterator; import javax.faces.FacesException; import javax.faces.application.NavigationHandler; import javax.faces.application.ViewExpiredException; import javax.faces.context.ExceptionHandler; import javax.faces.context.ExceptionHandlerWrapper; import javax.faces.context.FacesContext; import javax.faces.event.ExceptionQueuedEvent; import javax.faces.event.ExceptionQueuedEventContext; class CustomExceptionHandler extends ExceptionHandlerWrapper { private ExceptionHandler parent; public CustomExceptionHandler(ExceptionHandler parent) { this.parent = parent; } @Override public ExceptionHandler getWrapped() { return this.parent; } @Override public void handle() throws FacesException { for (Iterator<ExceptionQueuedEvent> i = getUnhandledExceptionQueuedEvents().iterator(); i.hasNext();) { ExceptionQueuedEvent event = i.next(); System.out.println("Iterating over ExceptionQueuedEvents. Current:" + event.toString()); ExceptionQueuedEventContext context = (ExceptionQueuedEventContext) event.getSource(); Throwable t = context.getException(); if (t instanceof ViewExpiredException) { ViewExpiredException vee = (ViewExpiredException) t; FacesContext fc = FacesContext.getCurrentInstance(); NavigationHandler nav = fc.getApplication().getNavigationHandler(); try { // Push some useful stuff to the flash scope for // use in the page fc.getExternalContext().getFlash().put("expiredViewId", vee.getViewId()); nav.handleNavigation(fc, null, "/login?faces-redirect=true"); fc.renderResponse(); } finally { i.remove(); } } } // At this point, the queue will not contain any ViewExpiredEvents. // Therefore, let the parent handle them. getWrapped().handle(); } } But STILL i'm NOT redirected to my error page - i'm getting the same HTTP 500 error like above. What am i doing wrong, what could be missing in my implementation so that the exception is handled correctly?

• After making a call programatically, my android app crashes

  - by Casidiablo

  Hello! The title explains all... I have this snippet of code in my application: String url = createTelUrl("3112007315"); Intent intent = new Intent(Intent.ACTION_CALL); intent.setData(Uri.parse(url)); context.startActivity(intent); It does make a call, but once the call ends, my application crashes. I'd like to return to my application once the call has finished, but I read this post and it seems not to be possible. So... is there anyway to at least pause my application and resume it once the call has finished? Thank you so much for reading.

• IIRF reverse proxy problem

  - by Sergei

  Hi everyone, We have a java application ( Atlassian Bamboo) running on port 8085 on Windows 2003. It is accessile as http: //bamboo:8085. I am trying to setup reverse proxy for IIS6 using IIRF so content is accessible via http: //bamboo. It seems that I set it ip correctly, and I can retrieve Status page. This is how my IIRF.ini looks like: RewriteLog c:\temp\iirf RewriteLogLevel 2 StatusUrl /iirfStatus RewriteCond %{HTTP_HOST} ^bambooi$ [I] #This setup works #ProxyPass ^/(.*)$ http://othersite/$1 #This does not ProxyPass ^/(.*)$ http://bamboo:8085/$1 However when I type in http: //bamboo in IE, I get 'page cannot be displayed ' message. FF does not return anything at all. I made Wireshark network dump, selected 'follow TCPstream' and it seems like correct page is being retrieved.Why cannot I see it then? I also noticed that I can retrieve http: //bamboo/favicon.ico so I must be very close to the solution.. This is the Wireshark output: GET / HTTP/1.1 Accept: image/gif, image/jpeg, image/pjpeg, image/pjpeg, application/x-shockwave-flash, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, application/x-ms-application, application/x-ms-xbap, application/vnd.ms-xpsdocument, application/xaml+xml, */* Accept-Language: en-gb User-Agent: Mozilla/4.0 (compatible;

• Flash Builder missing fundamental things

  - by Bart van Heukelom

  All of a sudden Flash Builder 4 is missing all kinds of fundamental things and is generating incorrect errors. I've had the same issue yesterday, where I fixed it by downloading a new Flex SDK and importing that into FB. I did this again, but this time it fixed nothing. I don't think it's something I did, like removing critical references from the build path. The errors also appeared on projects I was not working on at the time. It occurs for ActionScript, Flex and Flex Library projects alike. Update: I find this stack trace in the Flash Builder error log: !ENTRY com.adobe.flexbuilder.project 4 43 2010-05-11 11:55:47.495 !MESSAGE Uncaught exception in compiler !STACK 0 java.lang.NullPointerException at macromedia.asc.semantics.ConstantEvaluator.evaluate(ConstantEvaluator.java:2592) at macromedia.asc.parser.VariableBindingNode.evaluate(VariableBindingNode.java:64) at macromedia.asc.semantics.ConstantEvaluator.evaluate(ConstantEvaluator.java:2233) at macromedia.asc.parser.ListNode.evaluate(ListNode.java:44) at macromedia.asc.semantics.ConstantEvaluator.evaluate(ConstantEvaluator.java:2578) at macromedia.asc.parser.VariableDefinitionNode.evaluate(VariableDefinitionNode.java:48) at macromedia.asc.semantics.ConstantEvaluator.evaluate(ConstantEvaluator.java:2310) at macromedia.asc.parser.StatementListNode.evaluate(StatementListNode.java:60) at macromedia.asc.semantics.ConstantEvaluator.evaluate(ConstantEvaluator.java:2503) at macromedia.asc.parser.WithStatementNode.evaluate(WithStatementNode.java:44) at macromedia.asc.semantics.ConstantEvaluator.evaluate(ConstantEvaluator.java:2310) at macromedia.asc.parser.StatementListNode.evaluate(StatementListNode.java:60) at macromedia.asc.semantics.ConstantEvaluator.evaluate(ConstantEvaluator.java:2891) at macromedia.asc.parser.FunctionCommonNode.evaluate(FunctionCommonNode.java:106) at macromedia.asc.semantics.ConstantEvaluator.evaluate(ConstantEvaluator.java:2905) at macromedia.asc.parser.FunctionCommonNode.evaluate(FunctionCommonNode.java:106) at macromedia.asc.semantics.ConstantEvaluator.evaluate(ConstantEvaluator.java:3643) at macromedia.asc.parser.ClassDefinitionNode.evaluate(ClassDefinitionNode.java:106) at macromedia.asc.semantics.ConstantEvaluator.evaluate(ConstantEvaluator.java:3371) at macromedia.asc.parser.ProgramNode.evaluate(ProgramNode.java:80) at flex2.compiler.as3.As3Compiler.analyze4(As3Compiler.java:709) at flex2.compiler.CompilerAPI.analyze(CompilerAPI.java:3089) at flex2.compiler.CompilerAPI.analyze(CompilerAPI.java:2977) at flex2.compiler.CompilerAPI.batch2(CompilerAPI.java:528) at flex2.compiler.CompilerAPI.batch(CompilerAPI.java:1274) at flex2.compiler.CompilerAPI.compile(CompilerAPI.java:1496) at flex2.tools.oem.Application.compile(Application.java:1188) at flex2.tools.oem.Application.recompile(Application.java:1133) at flex2.tools.oem.Application.compile(Application.java:819) at flex2.tools.flexbuilder.BuilderApplication.compile(BuilderApplication.java:344) at com.adobe.flexbuilder.multisdk.compiler.internal.ASApplicationBuilder$MyBuilder.mybuild(ASApplicationBuilder.java:276) at com.adobe.flexbuilder.multisdk.compiler.internal.ASApplicationBuilder.build(ASApplicationBuilder.java:127) at com.adobe.flexbuilder.multisdk.compiler.internal.ASBuilder.build(ASBuilder.java:190) at com.adobe.flexbuilder.multisdk.compiler.internal.ASItemBuilder.build(ASItemBuilder.java:74) at com.adobe.flexbuilder.project.compiler.internal.FlexProjectBuilder.buildItem(FlexProjectBuilder.java:480) at com.adobe.flexbuilder.project.compiler.internal.FlexProjectBuilder.build(FlexProjectBuilder.java:306) at com.adobe.flexbuilder.project.compiler.internal.FlexIncrementalBuilder.build(FlexIncrementalBuilder.java:157) at org.eclipse.core.internal.events.BuildManager$2.run(BuildManager.java:627) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:170) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:201) at org.eclipse.core.internal.events.BuildManager$1.run(BuildManager.java:253) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:256) at org.eclipse.core.internal.events.BuildManager.basicBuildLoop(BuildManager.java:309) at org.eclipse.core.internal.events.BuildManager.build(BuildManager.java:341) at org.eclipse.core.internal.events.AutoBuildJob.doBuild(AutoBuildJob.java:140) at org.eclipse.core.internal.events.AutoBuildJob.run(AutoBuildJob.java:238) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55)

• Flex vs. jQuery vs. GWTvs./ Closre vs. Cappuccino vs. plain JS and HTML5?

  - by Laith J

  Hello, I'm creating my first web application and I'm really confused as to what technology to go for. My application needs to look serious (like an application), it doesn't need many colorful graphical interfaces. It only needs a toolbar, a tab bar, a split panel (preferably 3 columns), an easily-formatable text field, and a status bar. It will connect to a MySQL database through PHP (unless I go for GWT). Users will upload files. My evaluation of the options: Flex: Probably the easiest to develop but I'm pretty sure my application is something one would use on an iPad and with Flash's future on the iPad still unsure, I don't want to take the risk, otherwise Flex would've been my choice. jQuery: I've heard a lot about it and a lot of people recommend but I don't know how easy it is to use and how customizable the look of my app is. GWT: The problem with GWT is that it doesn't have many widgets. Another problem is that I'm gonna have to host the files in AppEngine's datastore and transfer them back and forth to a web server that will do operations on them (I need to process them) which adds more traffic and slows the process which worsens the user experience. Closure: It has a nice toolbar and a nice text field. I'm not sure how easy it is to use. Plus, I read an article that makes it sound really bad. Cappuccino: It has a very nice UI and it has a mac feel. I'm planning to give my application a mac feel anyway so this will save me a lot of theming. But if I go for this option I won't be able to make use of HTML5's new features (especially working offline). Plain JS and HTML5: This gives me the most flexibility but it is the hardest to work for. I'm sorry if this is subjective but I really need help with this.

• empty response body in ajax (or 206 Partial Content)

  - by Nikita Rybak

  Hi guys, I'm feeling completely stupid because I've spent two hours solving task which should be very simple and which I solved many times before. But now I'm not even sure in which direction to dig. I fail to fetch static content using ajax from local servers (Apache and Mongrel). I get responses 200 and 206 (depending on the server), empty response text (although Content-Length header is always correct), firebug shows request in red. Javascript is very generic, I'm getting same results even here: http://www.w3schools.com/ajax/tryit.asp?filename=tryajax_first (just change document location to 'http://localhost:3000/whatever') So, it's probably not the cause. Well, now I'm out of ideas. I can also post http headers, if it'll help. Thanks!

• Merge Word Documents (Office Interop & .NET), Keeping Formatting

  - by mbmccormick

  I'm having some difficulty merging multiple word documents together using Microsoft Office Interop Assemblies (Office 2007) and ASP.NET 3.5. I'm able to merge the documents, but some of my formatting is missing (namely the fonts and images). My current merge code is shown below. private void CombineDocuments() { object wdPageBreak = 7; object wdStory = 6; object oMissing = System.Reflection.Missing.Value; object oFalse = false; object oTrue = true; string fileDirectory = @"C:\documents\"; Microsoft.Office.Interop.Word.Application WordApp = new Microsoft.Office.Interop.Word.Application(); Microsoft.Office.Interop.Word.Document wDoc = WordApp.Documents.Add(ref oMissing, ref oMissing, ref oMissing, ref oMissing); string[] wordFiles = Directory.GetFiles(fileDirectory, "*.doc"); for (int i = 0; i < wordFiles.Length; i++) { string file = wordFiles[i]; wDoc.Application.Selection.Range.InsertFile(file, ref oMissing, ref oMissing, ref oMissing, ref oFalse); wDoc.Application.Selection.Range.InsertBreak(ref wdPageBreak); wDoc.Application.Selection.EndKey(ref wdStory, ref oMissing); } string combineDocName = Path.Combine(fileDirectory, "Merged Document.doc"); if (File.Exists(combineDocName)) File.Delete(combineDocName); object combineDocNameObj = combineDocName; wDoc.SaveAs(ref combineDocNameObj, ref m_WordDocumentType, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing); } I don't care necessarily how this is accomplished. It could output via PDF if it had to. I just want the formatting to carry over. Any help or hints that you could provide me with would be appreciated! Thanks!
