• Navigation in a #WP7 application with MVVM Light

  - by Laurent Bugnion

  In MVVM applications, it can be a bit of a challenge to send instructions to the view (for example a page) from a viewmodel. Thankfully, we have good tools at our disposal to help with that. In his excellent series “MVVM Light Toolkit soup to nuts”, Jesse Liberty proposes one approach using the MVVM Light messaging infrastructure. While this works fine, I would like to show here another approach using what I call a “view service”, i.e. an abstracted service that is invoked from the viewmodel, and implemented on the view. Multiple kinds of view services In fact, I use view services quite often, and even started standardizing them for the Windows Phone 7 applications I work on. If there is interest, I will be happy to show other such view services, for example Animation services, responsible to start/stop animations on the view. Dialog service, in charge of displaying messages to the user and gathering feedback. Navigation service, in charge of navigating to a given page directly from the viewmodel. In this article, I will concentrate on the navigation service. The INavigationService interface In most WP7 apps, the navigation service is used in quite a straightforward way. We want to: Navigate to a given URI. Go back. Be notified when a navigation is taking place, and be able to cancel. The INavigationService interface is quite simple indeed: public interface INavigationService { event NavigatingCancelEventHandler Navigating; void NavigateTo(Uri pageUri); void GoBack(); } Obviously, this interface can be extended if necessary, but in most of the apps I worked on, I found that this covers my needs. The NavigationService class It is possible to nicely pack the navigation service into its own class. To do this, we need to remember that all the PhoneApplicationPage instances use the same instance of the navigation service, exposed through their NavigationService property. In fact, in a WP7 application, it is the main frame (RootFrame, of type PhoneApplicationFrame) that is responsible for this task. So, our implementation of the NavigationService class can leverage this. First the class will grab the PhoneApplicationFrame and store a reference to it. Also, it registers a handler for the Navigating event, and forwards the event to the listening viewmodels (if any). Then, the NavigateTo and the GoBack methods are implemented. They are quite simple, because they are in fact just a gateway to the PhoneApplicationFrame. The whole class is as follows: public class NavigationService : INavigationService { private PhoneApplicationFrame _mainFrame; public event NavigatingCancelEventHandler Navigating; public void NavigateTo(Uri pageUri) { if (EnsureMainFrame()) { _mainFrame.Navigate(pageUri); } } public void GoBack() { if (EnsureMainFrame() && _mainFrame.CanGoBack) { _mainFrame.GoBack(); } } private bool EnsureMainFrame() { if (_mainFrame != null) { return true; } _mainFrame = Application.Current.RootVisual as PhoneApplicationFrame; if (_mainFrame != null) { // Could be null if the app runs inside a design tool _mainFrame.Navigating += (s, e) => { if (Navigating != null) { Navigating(s, e); } }; return true; } return false; } } Exposing URIs I find that it is a good practice to expose each page’s URI as a constant. In MVVM Light applications, a good place to do that is the ViewModelLocator, which already acts like a central point of setup for the views and their viewmodels. Note that in some cases, it is necessary to expose the URL as a string, for instance when a query string needs to be passed to the view. So for example we could have: public static readonly Uri MainPageUri = new Uri("/MainPage.xaml", UriKind.Relative); public const string AnotherPageUrl = "/AnotherPage.xaml?param1={0}&param2={1}"; Creating and using the NavigationService Normally, we only need one instance of the NavigationService class. In cases where you use an IOC container, it is easy to simply register a singleton instance. For example, I am using a modified version of a super simple IOC container, and so I can register the navigation service as follows: SimpleIoc.Register<INavigationService, NavigationService>(); Then, it can be resolved where needed with: SimpleIoc.Resolve<INavigationService>(); Or (more frequently), I simply declare a parameter on the viewmodel constructor of type INavigationService and let the IOC container do its magic and inject the instance of the NavigationService when the viewmodel is created. On supported platforms (for example Silverlight 4), it is also possible to use MEF. Or, of course, we can simply instantiate the NavigationService in the ViewModelLocator, and pass this instance as a parameter of the viewmodels’ constructor, injected as a property, etc… Once the instance has been passed to the viewmodel, it can be used, for example with: NavigationService.NavigateTo(ViewModelLocator.ComparisonPageUri); Testing Thanks to the INavigationService interface, navigation can be mocked and tested when the viewmodel is put under unit test. Simply implement and inject a mock class, and assert that the methods are called as they should by the viewmodel. Conclusion As usual, there are multiple ways to code a solution answering your needs. I find that view services are a really neat way to delegate view-specific responsibilities such as animation, dialogs and of course navigation to other classes through an abstracted interface. In some cases, such as the NavigationService class exposed here, it is even possible to standardize the implementation and pack it in a class library for reuse. I hope that this sample is useful! Happy coding. Laurent   Laurent Bugnion (GalaSoft) Subscribe | Twitter | Facebook | Flickr | LinkedIn

• Access Control Service: Handling Errors

  - by Your DisplayName here!

  Another common problem with external authentication is how to deal with sign in errors. In active federation like WS-Trust there are well defined SOAP faults to communicate problem to a client. But with web applications, the error information is typically generated and displayed on the external sign in page. The relying party does not know about the error, nor can it help the user in any way. The Access Control Service allows to post sign in errors to a specified page. You setup this page in the relying party registration. That means that whenever an error occurs in ACS, the error information gets packaged up as a JSON string and posted to the page specified. This way you get structued error information back into you application so you can display a friendlier error message or log the error. I added error page support to my ACS2 sample, which can be downloaded here. How to turn the JSON error into CLR types The JSON schema is reasonably simple, the following class turns the JSON into an object: [DataContract] public class AcsErrorResponse {     [DataMember(Name = "context", Order = 1)]     public string Context { get; set; }     [DataMember(Name = "httpReturnCode", Order = 2)]     public string HttpReturnCode { get; set; }     [DataMember(Name = "identityProvider", Order = 3)]        public string IdentityProvider { get; set; }     [DataMember(Name = "timeStamp", Order = 4)]     public string TimeStamp { get; set; }     [DataMember(Name = "traceId", Order = 5)]     public string TraceId { get; set; }     [DataMember(Name = "errors", Order = 6)]     public List<AcsError> Errors { get; set; }     public static AcsErrorResponse Read(string json)     {         var serializer = new DataContractJsonSerializer( typeof(AcsErrorResponse));         var response = serializer.ReadObject( new MemoryStream(Encoding.Default.GetBytes(json))) as AcsErrorResponse;         if (response != null)         {             return response;         }         else         {             throw new ArgumentException("json");         }     } } [DataContract] public class AcsError {     [DataMember(Name = "errorCode", Order = 1)]     public string Code { get; set; }             [DataMember(Name = "errorMessage", Order = 2)]     public string Message { get; set; } } Retrieving the error information You then need to provide a page that takes the POST and deserializes the information. My sample simply fills a view that shows all information. But that’s for diagnostic/sample purposes only. You shouldn’t show the real errors to your end users. public class SignInErrorController : Controller {     [HttpPost]     public ActionResult Index()     {         var errorDetails = Request.Form["ErrorDetails"];         var response = AcsErrorResponse.Read(errorDetails);         return View("SignInError", response);     } } Also keep in mind that the error page is an anonymous page and that you are taking external input. So all the usual input validation applies.

• Visual View for Schema Based Editor

  - by Geertjan

  Starting from yesterday's blog entry, make the following change in the DataObject's constructor: registerEditor("text/x-sample+xml", true); I.e., the MultiDataObject.registerEditor method turns the editor into a multiview component. Now, again, within the DataObject, add the following, to register a source editor in the multiview component: @MultiViewElement.Registration(         displayName = "#LBL_Sample_Source",         mimeType = "text/x-sample+xml",         persistenceType = TopComponent.PERSISTENCE_NEVER,         preferredID = "ShipOrderSourceView",         position = 1000) @NbBundle.Messages({     "LBL_Sample_Source=Source" }) public static MultiViewElement createEditor(Lookup lkp){     return new MultiViewEditorElement(lkp); } Result: Next, let's create a visual editor in the multiview component. This could be within the same module as the above or within a completely separate module. That makes it possible for external contributors to provide modules with new editors in an existing multiview component: @MultiViewElement.Registration(displayName = "#LBL_Sample_Visual", mimeType = "text/x-sample+xml", persistenceType = TopComponent.PERSISTENCE_NEVER, preferredID = "VisualEditorComponent", position = 500) @NbBundle.Messages({ "LBL_Sample_Visual=Visual" }) public class VisualEditorComponent extends JPanel implements MultiViewElement {     public VisualEditorComponent() {         initComponents();     }     @Override     public String getName() {         return "VisualEditorComponent";     }     @Override     public JComponent getVisualRepresentation() {         return this;     }     @Override     public JComponent getToolbarRepresentation() {         return new JToolBar();     }     @Override     public Action[] getActions() {         return new Action[0];     }     @Override     public Lookup getLookup() {         return Lookup.EMPTY;     }     @Override     public void componentOpened() {     }     @Override     public void componentClosed() {     }     @Override     public void componentShowing() {     }     @Override     public void componentHidden() {     }     @Override     public void componentActivated() {     }     @Override     public void componentDeactivated() {     }     @Override     public UndoRedo getUndoRedo() {         return UndoRedo.NONE;     }     @Override     public void setMultiViewCallback(MultiViewElementCallback callback) {     }     @Override     public CloseOperationState canCloseElement() {         return CloseOperationState.STATE_OK;     } } Result: Next, the DataObject is automatically returned from the Lookup of DataObject. Therefore, you can go back to your visual editor, add a LookupListener, listen for DataObjects, parse the underlying XML file, and display values in GUI components within the visual editor.

• StreamInsight 2.1 Released

  - by Roman Schindlauer

  The wait is over—we are pleased to announce the release of StreamInsight 2.1. Since the release of version 1.2, we have heard your feedbacks and suggestions and based on that we have come up with a whole new set of features. Here are some of the highlights: A New Programming Model – A more clear and consistent object model, eliminating the need for complex input and output adapters (though they are still completely supported). This new model allows you to provision, name, and manage data sources and sinks in the StreamInsight server. Tight integration with Reactive Framework (Rx) – You can write reactive queries hosted inside StreamInsight as well as compose temporal queries on reactive objects. High Availability – Check-pointing over temporal streams and multiple processes with shared computation. Here is how simple coding can be with the 2.1 Programming Model: class Program {     static void Main(string[] args)     {         using (Server server = Server.Create("Default"))         {             // Create an app             Application app = server.CreateApplication("app");             // Define a simple observable which generates an integer every second             var source = app.DefineObservable(() =>                 Observable.Interval(TimeSpan.FromSeconds(1)));             // Define a sink.             var sink = app.DefineObserver(() =>                 Observer.Create<long>(x => Console.WriteLine(x)));             // Define a query to filter the events             var query = from e in source                         where e % 2 == 0                         select e;             // Bind the query to the sink and create a runnable process             using (IDisposable proc = query.Bind(sink).Run("MyProcess"))             {                 Console.WriteLine("Press a key to dispose the process...");                 Console.ReadKey();             }         }     } }   That’s how easily you can define a source, sink and compose a query and run it. Note that we did not replace the existing APIs, they co-exist with the new surface. Stay tuned, you will see a series of articles coming out over the next few weeks about the new features and how to use them. Come and grab it from our download center page and let us know what you think! You can find the updated MSDN documentation here, and we would appreciate if you could provide feedback to the docs as well—best via email to [email protected]. Moreover, we updated our samples to demonstrate the new programming surface. Regards, The StreamInsight Team

• GCM: onMessage() from GCMIntentService is never called [migrated]

  - by Shrikant

  I am implementing GCM (Google Cloud Messaging- PUSH Notifications) in my application. I have followed all the steps given in GCM tutorial from developer.android.com My application's build target is pointing to Goolge API 8 (Android 2.2 version). I am able to get the register ID from GCM successfully, and I am passing this ID to my application server. So the registration step is performed successfully. Now when my application server sends a PUSH message to my device, the server gets the message as SUCCESS=1 FAILURE=0, etc., i.e. Server is sending message successfully, but my device never receives the message. After searching alot about this, I came to know that GCM pushes messages on port number 5228, 5229 or 5230. Initially, my device and laptop was restricted for some websites, but then I was granted all the permissions to access all websites, so I guess these port numbers are open for my device. So my question is: I never receive any PUSH message from GCM. My onMessage() from GCMIntenService class is never called. What could be the reason? Please see my following code and guide me accordingly: I have declared following in my manifest: <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="8" /> <permission android:name="package.permission.C2D_MESSAGE" android:protectionLevel="signature" /> <!-- App receives GCM messages. --> <uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" /> <!-- GCM connects to Google Services. --> <uses-permission android:name="android.permission.INTERNET" /> <!-- GCM requires a Google account. --> <uses-permission android:name="android.permission.GET_ACCOUNTS" /> <!-- Keeps the processor from sleeping when a message is received. --> <uses-permission android:name="android.permission.WAKE_LOCK" /> <uses-permission android:name="package.permission.C2D_MESSAGE" /> <uses-permission android:name="android.permission.INTERNET" /> <receiver android:name="com.google.android.gcm.GCMBroadcastReceiver" android:permission="com.google.android.c2dm.permission.SEND" > <intent-filter> <action android:name="com.google.android.c2dm.intent.RECEIVE" /> <action android:name="com.google.android.c2dm.intent.REGISTRATION" /> <category android:name="packageName" /> </intent-filter> </receiver> <receiver android:name=".ReceiveBroadcast" android:exported="false" > <intent-filter> <action android:name="GCM_RECEIVED_ACTION" /> </intent-filter> </receiver> <service android:name=".GCMIntentService" /> /** * @author Shrikant. * */ public class GCMIntentService extends GCMBaseIntentService { /** * The Sender ID used for GCM. */ public static final String SENDER_ID = "myProjectID"; /** * This field is used to call Web-Service for GCM. */ SendUserCredentialsGCM sendUserCredentialsGCM = null; public GCMIntentService() { super(SENDER_ID); sendUserCredentialsGCM = new SendUserCredentialsGCM(); } @Override protected void onRegistered(Context arg0, String registrationId) { Log.i(TAG, "Device registered: regId = " + registrationId); sendUserCredentialsGCM.sendRegistrationID(registrationId); } @Override protected void onUnregistered(Context context, String arg1) { Log.i(TAG, "unregistered = " + arg1); sendUserCredentialsGCM .unregisterFromGCM(LoginActivity.API_OR_BROWSER_KEY); } @Override protected void onMessage(Context context, Intent intent) { Log.e("GCM MESSAGE", "Message Recieved!!!"); String message = intent.getStringExtra("message"); if (message == null) { Log.e("NULL MESSAGE", "Message Not Recieved!!!"); } else { Log.i(TAG, "new message= " + message); sendGCMIntent(context, message); } } private void sendGCMIntent(Context context, String message) { Intent broadcastIntent = new Intent(); broadcastIntent.setAction("GCM_RECEIVED_ACTION"); broadcastIntent.putExtra("gcm", message); context.sendBroadcast(broadcastIntent); } @Override protected void onError(Context context, String errorId) { Log.e(TAG, "Received error: " + errorId); Toast.makeText(context, "PUSH Notification failed.", Toast.LENGTH_LONG) .show(); } @Override protected boolean onRecoverableError(Context context, String errorId) { return super.onRecoverableError(context, errorId); } }

However I get the impression that the CPU got's hotter in average than without this file. What changes from 13.10 to 14.04 may be responsible for this? If this is a bug, for which package I should report the bug?

• Server.transfer causing HttpException

  I am developing a C#/SQL ASP.NET web application in VS 2008. Currently I am using the Server.Transfer method to transfer control from one ASPX.CS file to another ASPX file. The first time through, this works. But after control is transferred to this new file it encounters a condition: if (restart == false) { where "restart" is a boolean variable. After this statement it immediately transfers control back to the same ASPX.CS file and tries to reexecute the Server.Transfer method. This time it gives me the following exception and stack trace. Do you know what is causing this? I tried to read this but it didn't make much sense to me. System.Web.HttpException was unhandled by user code Message="Error executing child request for DataMatch.aspx." Source="System.Web" ErrorCode=-2147467259 StackTrace: at System.Web.HttpServerUtility.Execute(String path, TextWriter writer, Boolean preserveForm) at System.Web.HttpServerUtility.Transfer(String

• marshal data too short!!!

  - by Nitin Garg

  My application requires to keep large data objects in session. There are like 3-4 data objects each created by parsing a csv containing 150 X 20 cells having strings of 3-4 characters. My application shows this error- "marshal data too short". I tried this- Deleting the old session table. Deleting the old migration for session table. Creating a new migration using rake db: sessions:create. editing the migration manually, changing "text: data" to "longtext: data". running the migration using rake db: migrate. now when i open my application, i see this page- link text please someone help me, this is getting on my nerves!! other details of application-- In view "index.html.erb"- There is a link that makes ajax call to an action in controller, that action parses large csv file and makes an object out of it. this object is stored in session. ERROR LOG ` ArgumentError in Scoring#index Showing app/views/scoring/index.html.erb where line #4 raised: marshal data too short Extracted source (around line #4): 1: 2: 3: 4: <%= link_to_remote "get

• "Exception has been thrown by the target of an invocation" Running Tests - VS2008 SP1

  - by omatrot

  I'm using Visual Studio 2008 Team Suite and I'm unable to run tests and display the Test/Windows/Test Result Window. The result is a dialog box with the following content : "Exception has been thrown by the target of an invocation". Team Explorer has been installed after Visual Studio 2008 SP1. So I have re-apllied the service pack. Searching the web I found that this error is pretty common but unfortunately, the proposed solutions does not work for me. The problem was never analysed so I decided to give it a try : I reproduced the problem on a computer, attached the process with windbg and start with the basic investigations.

Any help appreciated. TIA. Olivier.

• ie7 innerhtml strange display problem

  - by thoraniann

  Hello, I am having a strange problem with ie7 (ie8 in compatibility mode). I have div containers where I am updating values using javascript innhtml to update the values. This works fine in Firefox and ie8. In ie7 the values do not update but if a click on the values and highlight them then they update, also if a change the height of the browser then on the next update the values get updated correctly. I have figured out that if I change the position property of the outer div container from relative to static then the updates work correctly. The page can be viewed here http://islendingasogur.net/test/webmap_html_test.html In internet explorer 8 with compatibility turned on you can see that the timestamp in the gray box only gets updated one time, after that you see no changes. The timestamp in the lower right corner gets updated every 10 seconds. But if you highlight the text in the gray box then the updated timestamp values appears! Here is the page: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html;

I have only seen this error in ie8 with compatibility turned on. If anybody has seen this before and has a fix, I would be very grateful. Thanks.

• Wikipedia API: list=alllinks confusion

  - by Chris Salij

  I'm doing a research project for the summer and I've got to use get some data from Wikipedia, store it and then do some analysis on it. I'm using the Wikipedia API to gather the data and I've got that down pretty well. What my questions is in regards to the links-alllinks option in the API doc here After reading the description, both there and in the API itself (it's down and bit and I can't link directly to the section), I think I understand what it's supposed to return. However when I ran a query it gave me back something I didn't expect. Here's the query I ran: http://en.wikipedia.org/w/api.php?action=query&prop=revisions&titles=google&rvprop=ids|timestamp|user|comment|content&rvlimit=1&list=alllinks&alunique&allimit=40&format=xml Which in essence says: Get the last revision of the Google page, include the id, timestamp, user, comment and content of each revision, and return it in XML format. The allinks (I thought) should give me back a list of wikipedia pages which point to the google page (In this case the first 40 unique ones). I'm not sure what the policy is on swears, but this is the result I got back exactly: <?xml version="1.0"?> <api> <query><normalized> <n from="google" to="Google" /> </normalized> <pages> <page pageid="1092923" ns="0" title="Google"> <revisions> <rev revid="366826294" parentid="366673948" user="Citation bot" timestamp="2010-06-08T17:18:31Z" comment="Citations: [161]Tweaked: url.

Why am I getting this crap in there? Thanks for your help

• HTML client-side portable file generation - no external resources or server calls

  - by awashburn

  I have the following situation: I have set up a series of Cron jobs on an internal company server to run various PHP scripts designed to check data integrity. Each PHP script queries a company database, formats the returned query data into an HTML file containing one or more <tables>, and then mails the HTML file to several client emails as an attachment. From my experience, most of the PHP scripts generate HTML files with only a few tables, however there are a few PHP scripts the create HTML files with around 30 tables. HTML files have been chosen as the distribution format of these scans because HTML makes it easy to view many tables at once in a browser window. I would like to add the functionality for the clients to download a table in the HTML file as a CSV file. I anticipate clients using this feature when they suspect a data integrity issue based on the table data. It would be ideal for them to be able to take the table in question, export the data out to a CSV file, and then study it further. Because need for exporting the data to CSV format is at the discretion of the client, unpredictable as to what table will be under scrutiny, and intermittently used I do not want to create CSV files for every table. Normally creating a CSV file wouldn't be too difficult, using JavaScript/jQuery to preform DOM traversal and generate the CSV file data into a string utilizing a server call or flash library to facilitate the download process; but I have one limiting constraint: The HTML file needs to be "portable." I would like the clients to be able to take their HTML file and preform analysis of the data outside the company intranet. Also it is likely these HTML files will be archived, so making the export functionality "self contained" in the HTML files is a highly desirable feature for the two previous reasons. The "portable" constraint of CSV file generation from a HTML file means: I cannot make a server call. This means ALL the file generation must be done client-side. I want the single HTML file attached to the email to contain all the resources to generate the CSV file. This means I cannot use jQuery or flash libraries to generate the file. I understand, for obvious security reasons, that writing out files to disk using JavaScript isn't supported by any browser. I don't want to create a file without the user knowledge; I would like to generate the file using JavaScript in memory and then prompt the user the "download" the file from memory. I have looked into generating the CSV file as a URI however, according to my research and testing, this approach has a few problems: URIs for files are not supported by IE (See Here) URIs in FireFox saves the file with a random file name and as a .part file As much as it pains me, I can accept the fact the IE<=v9 won't create a URI for files. I would like to create a semi-cross-browser solution in which Chrome, Firefox, and Safari create a URI to download the CSV file after JavaScript DOM traversal compiles the data. My Example Table: <table> <thead class="resulttitle"> <tr> <th style="text-align:center;" colspan="3"> NameOfTheTable</th> </tr> </thead> <tbody> <tr class="resultheader"> <td>VEN_PK</td> <td>VEN_CompanyName</td> <td>VEN_Order</td> </tr> <tr> <td class='resultfield'>1</td> <td class='resultfield'>Brander Ranch</td> <td class='resultfield'>Beef</td> </tr> <tr> <td class='resultfield'>2</td> <td class='resultfield'>Super Tree Produce</td> <td class='resultfield'>Apples</td> </tr> <tr> <td class='resultfield'>3</td> <td class='resultfield'>John's Distilery</td> <td class='resultfield'>Beer</td> </tr> </tbody> <tfoot> <tr> <td colspan="3" style="text-align:right;"> <button onclick="doSomething(this);">Export to CSV File</button></td> </tr> </tfoot> </table> My Example JavaScript: <script type="text/javascript"> function doSomething(inButton) { /* locate elements */ var table = inButton.parentNode.parentNode.parentNode.parentNode; var name = table.rows[0].cells[0].textContent; var tbody = table.tBodies[0]; /* create CSV String through DOM traversal */ var rows = tbody.rows; var csvStr = ""; for (var i=0; i < rows.length; i++) { for (var j=0; j < rows[i].cells.length; j++) { csvStr += rows[i].cells[j].textContent +","; } csvStr += "\n"; } /* temporary proof DOM traversal was successful */ alert("Table Name:\t" + name + "\nCSV String:\n" + csvStr); /* Create URI Here! * (code I am missing) */ /* Approach 1 : Auto-download * downloads CSV data but: * In FireFox downloads as randomCharacers.part instead of name.csv * In Chrome downloads without prompting the user * In Safari opens the files in browser (textfile) */ //var hrefData = "data:text/csv;charset=US-ASCII," + encodeURIComponent(csvStr); //document.location.href = hrefData; /* Approach 2 : Right-Click Save As... */ var hrefData = "data:text/csv;charset=US-ASCII," + encodeURIComponent(csvStr); var fileLink = document.createElement("a"); fileLink.href = hrefData; fileLink.innerHTML = "download"; parentTD = inButton.parentNode; parentTD.appendChild(fileLink); parentTD.removeChild(inButton); } </script> I am looking for an example solution in which the above example table can be downloaded as a CSV file: using a URI the user is prompted to save the file the default filename is the name of the table. code works as described in modern versions of FireFox, Safari, & Chrome I have added a <script> tag with the DOM traversal function doSomething(). The real help I need is with formatting the URI to what I want within the doSomething() function.

• Xml failing to deserialise

  - by Carnotaurus

  I call a method to get my pages [see GetPages(String xmlFullFilePath)]. The FromXElement method is supposed to deserialise the LitePropertyData elements to strongly type LitePropertyData objects. Instead it fails on the following line: return (T)xmlSerializer.Deserialize(memoryStream); and gives the following error: <LitePropertyData xmlns=''> was not expected. What am I doing wrong? I have included the methods that I call and the xml data: public static T FromXElement<T>(this XElement xElement) { using (var memoryStream = new MemoryStream(Encoding.ASCII.GetBytes(xElement.ToString()))) { var xmlSerializer = new XmlSerializer(typeof(T)); return (T)xmlSerializer.Deserialize(memoryStream); } } public static List<LitePageData> GetPages(String xmlFullFilePath) { XDocument document = XDocument.Load(xmlFullFilePath); List<LitePageData> results = (from record in document.Descendants("row") select new LitePageData { Guid = IsValid(record, "Guid") ? record.Element("Guid").Value : null, ParentID = IsValid(record, "ParentID") ? Convert.ToInt32(record.Element("ParentID").Value) : (Int32?)null, Created = Convert.ToDateTime(record.Element("Created").Value), Changed = Convert.ToDateTime(record.Element("Changed").Value), Name = record.Element("Name").Value, ID = Convert.ToInt32(record.Element("ID").Value), LitePageTypeID = IsValid(record, "ParentID") ? Convert.ToInt32(record.Element("ParentID").Value) : (Int32?)null, Html = record.Element("Html").Value, FriendlyName = record.Element("FriendlyName").Value, Properties = record.Element("Properties") != null ? record.Element("Properties").Element("LitePropertyData").FromXElement<List<LitePropertyData>>() : new List<LitePropertyData>() }).ToList(); return results; } Here is the xml: <?xml version="1.0" encoding="utf-8"?> <root> <rows> <row> <ID>1</ID> <ImageUrl></ImageUrl> <Html>Home page</Html> <Created>01-01-2012</Created> <Changed>01-01-2012</Changed> <Name>Home page</Name> <FriendlyName>home-page</FriendlyName> </row> <row xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <Guid>edeaf468-f490-4271-bf4d-be145bc6a1fd</Guid> <ID>8</ID> <Name>Unused</Name> <ParentID>1</ParentID> <Created>2006-03-25T10:57:17</Created> <Changed>2012-07-17T12:24:30.0984747+01:00</Changed> <ChangedBy /> <LitePageTypeID xsi:nil="true" /> <Html> What is the purpose of this option? This option checks the current document for accessibility issues. It uses Bobby to provide details of whether the current web page conforms to W3C's WCAG criteria for web content accessibility. Issues with Bobby and Cynthia Bobby and Cynthia are free services that supposedly allow a user to expose web page accessibility barriers. It is something of a guide but perhaps a blunt instrument. I tested a few of the webpages that I have designed. Sure enough, my pages fall short and for good reason. I am not about to claim that Bobby and Cynthia are useless. Although it is useful and commendable tool, it project appears to be overly ambitious. Nevertheless, let me explain my issues with Bobby and Cynthia: First, certain W3C standards for designing web documents are often too strict and unworkable. For instance, in some versions W3C standards for HTML, certain tags should not include a particular attribute, whereas in others they are requisite if the document is to be ???well-formed???. The standard that a designer chooses is determined usually by the requirements specification document. This specifies which browsers and versions of those browsers that the web page is expected to correctly display. Forcing a hypertext document to conform strictly to a specific W3C standard for HTML is often no simple task. In the worst case, it cannot conform without losing some aesthetics or accessibility functionality. Second, the case of HTML documents is not an isolated case. Standards for XML, XSL, JavaScript, VBScript, are analogous. Therefore, you might imagine the problems when you begin to combine these languages and formats in an HTML document. Third, there is always more than one way to skin a cat. For example, Bobby and Cynthia may flag those IMG tags that do not contain a TITLE attribute. There might be good reason that a web developer chooses not to include the title attribute. The title attribute has a limited numbers of characters and does not support carriage returns. This is a major defect in the design of this tag. In fact, before the TITLE attribute was supported, there was the ALT attribute. Most browsers support both, yet they both perform a similar function. However, both attributes share the same deficiencies. In practice, there are instances where neither attribute would be used. Instead, for example, the developer would write some JavaScript or VBScript to circumvent these deficiencies. The concern is that Bobby and Cynthia would not notice this because it does not ???understand??? what the JavaScript does. </Html> <FriendlyName>unused</FriendlyName> <IsDeleted>false</IsDeleted> <Properties> <LitePropertyData> <Description>Image for the page</Description> <DisplayEditUI>true</DisplayEditUI> <OwnerTab>1</OwnerTab> <DisplayName>Image Url</DisplayName> <FieldOrder>1</FieldOrder> <IsRequired>false</IsRequired> <Name>ImageUrl</Name> <IsModified>false</IsModified> <ParentPageID>3</ParentPageID> <Type>String</Type> <Value xsi:type="xsd:string">smarter.jpg</Value> </LitePropertyData> <LitePropertyData> <Description>WebItemApplicationEnum</Description> <DisplayEditUI>true</DisplayEditUI> <OwnerTab>1</OwnerTab> <DisplayName>WebItemApplicationEnum</DisplayName> <FieldOrder>1</FieldOrder> <IsRequired>false</IsRequired> <Name>WebItemApplicationEnum</Name> <IsModified>false</IsModified> <ParentPageID>3</ParentPageID> <Type>Number</Type> <Value xsi:type="xsd:string">1</Value> </LitePropertyData> </Properties> <Seo> <Author>Phil Carney</Author> <Classification /> <Copyright>Carnotaurus</Copyright> <Description> What is the purpose of this option?

• How to edit item in a listbox shown from reading a .csv file?

  - by Shuvo

  I am working in a project where my application can open a .csv file and read data from it. The .csv file contains the latitude, longitude of places. The application reads data from the file shows it in a static map and display icon on the right places. The application can open multiple file at a time and it opens with a new tab every time. But I am having trouble in couple of cases When I am trying to add a new point to the .csv file opened. I am able to write new point on the same file instead adding a new point data to the existing its replacing others and writing the new point only. I cannot use selectedIndexChange event to perform edit option on the listbox and then save the file. Any direction would be great. using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms;

• Null reading in stream images? Unable to start activity ComponentInfo

  - by lasmith

  I have reviewed a lot of similar questions regarding not being able to launch an activity but they don't seem to quite match my problem. I am working on a simple black jack game but its force quitting. I suspect there is a problem with loading up the card png images I have. Stepping through the debugger it crashes right while in the resetGame() function. I'm sure I am doing something dumb. My Logcat: 10-15 20:21:43.309: E/AndroidRuntime(2863): FATAL EXCEPTION: main 10-15 20:21:43.309: E/AndroidRuntime(2863): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.smith.blackjack/com.smith.blackjack.Main}: java.lang.NullPointerException 10-15 20:21:43.309: E/AndroidRuntime(2863): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2059) 10-15 20:21:43.309: E/AndroidRuntime(2863): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2084) 10-15 20:21:43.309: E/AndroidRuntime(2863): at android.app.ActivityThread.access$600(ActivityThread.java:130) 10-15 20:21:43.309: E/AndroidRuntime(2863): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1195) 10-15 20:21:43.309: E/AndroidRuntime(2863): at android.os.Handler.dispatchMessage(Handler.java:99) 10-15 20:21:43.309: E/AndroidRuntime(2863): at android.os.Looper.loop(Looper.java:137) 10-15 20:21:43.309: E/AndroidRuntime(2863): at android.app.ActivityThread.main(ActivityThread.java:4745) 10-15 20:21:43.309: E/AndroidRuntime(2863): at java.lang.reflect.Method.invokeNative(Native Method) 10-15 20:21:43.309: E/AndroidRuntime(2863): at java.lang.reflect.Method.invoke(Method.java:511) 10-15 20:21:43.309: E/AndroidRuntime(2863): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:786) 10-15 20:21:43.309: E/AndroidRuntime(2863): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:553) 10-15 20:21:43.309: E/AndroidRuntime(2863): at dalvik.system.NativeStart.main(Native Method) 10-15 20:21:43.309: E/AndroidRuntime(2863): Caused by: java.lang.NullPointerException 10-15 20:21:43.309: E/AndroidRuntime(2863): at com.smith.blackjack.DeckOfCards.<init>(DeckOfCards.java:17) 10-15 20:21:43.309: E/AndroidRuntime(2863): at com.smith.blackjack.Main.resetGame(Main.java:98) 10-15 20:21:43.309: E/AndroidRuntime(2863): at com.smith.blackjack.Main.onCreate(Main.java:67) 10-15 20:21:43.309: E/AndroidRuntime(2863): at android.app.Activity.performCreate(Activity.java:5008) 10-15 20:21:43.309: E/AndroidRuntime(2863): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1079) 10-15 20:21:43.309: E/AndroidRuntime(2863): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2023) 10-15 20:21:43.309: E/AndroidRuntime(2863): ... 11 more My androidmanifest: <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.smith.blackjack" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="11" android:targetSdkVersion="15" /> <application android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <activity android:name=".Main" android:label="@string/title_activity_main" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> Here is my Main.java package com.smith.blackjack;

  I have this weird problem in java when trying to fetch records from MYSql database by using the limit function in the query. Not sure what went wrong or did wrong, this query is giving me a hard time. Issue - When I run this query through my java program it returns all the records and not limiting the records to 10 as given in the limit.

• Make @JsonTypeInfo property optional

  - by Mark Peters

  I'm using @JsonTypeInfo to instruct Jackson to look in the @class property for concrete type information. However, sometimes I don't want to have to specify @class, particularly when the subtype can be inferred given the context. What's the best way to do that? Here's an example of the JSON: { "owner": {"name":"Dave"}, "residents":[ {"@class":"jacksonquestion.Dog","breed":"Greyhound"}, {"@class":"jacksonquestion.Human","name":"Cheryl"}, {"@class":"jacksonquestion.Human","name":"Timothy"} ] } and I'm trying to deserialize them into these classes (all in jacksonquestion.*): public class Household { private Human owner; private List<Animal> residents; public Human getOwner() { return owner; } public void setOwner(Human owner) { this.owner = owner; } public List<Animal> getResidents() { return residents; } public void setResidents(List<Animal> residents) { this.residents = residents; } } public class Animal {} public class Dog extends Animal { private String breed; public String getBreed() { return breed; } public void setBreed(String breed) { this.breed = breed; } } public class Human extends Animal { private String name; public String getName() { return name; } public void setName(String name) { this.name = name; } } using this config: @JsonTypeInfo(use = JsonTypeInfo.Id.CLASS, include = JsonTypeInfo.As.PROPERTY, property = "@class") private static class AnimalMixin { } //... ObjectMapper objectMapper = new ObjectMapper(); objectMapper.getDeserializationConfig().addMixInAnnotations(Animal.class, AnimalMixin.class); Household household = objectMapper.readValue(json, Household.class); System.out.println(household); As you can see, the owner is declared as a Human, not an Animal, so I want to be able to omit @class and have Jackson infer the type as it normally would. When I run this though, I get org.codehaus.jackson.map.JsonMappingException: Unexpected token (END_OBJECT), expected FIELD_NAME: missing property '@class' that is to contain type id (for class jacksonquestion.Human) Since "owner" doesn't specify @class. Any ideas? One initial thought I had was to use @JsonTypeInfo on the property rather than the type. However, this cannot be leveraged to annotate the element type of a list.

• Routing audio to Bluetooth Headset (non-A2DP) on Android

  - by Jayesh

  I have a non-A2DP single ear BT headset (Plantronics 510) and would like to use it with my Android HTC Magic to listen to low quality audio like podcasts/audio books. After much googling I found that only phone call audio can be routed to the non-A2DP BT headsets. (I would like to know if you have found a ready solution to route all kinds of audio to non-A2DP BT headsets) So I figured, somehow programmatically I can channel the audio to the stream that carries phone call audio. This way I will fool the phone to carry my mp3 audio to my BT headset. I wrote following simple code. import android.content.*; import android.app.Activity; import android.os.Bundle; import android.media.*; import java.io.*; import android.util.Log; public class BTAudioActivity extends Activity { private static final String TAG = "BTAudioActivity"; private MediaPlayer mPlayer = null; private AudioManager amanager = null; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); amanager = (AudioManager) getSystemService(Context.AUDIO_SERVICE); amanager.setBluetoothScoOn(true); amanager.setMode(AudioManager.MODE_IN_CALL); mPlayer = new MediaPlayer(); try { mPlayer.setDataSource(new FileInputStream( "/sdcard/sample.mp3").getFD()); mPlayer.setAudioStreamType(AudioManager.STREAM_VOICE_CALL); mPlayer.prepare(); mPlayer.start(); } catch(Exception e) { Log.e(TAG, e.toString()); } } @Override public void onDestroy() { mPlayer.stop(); amanager.setMode(AudioManager.MODE_NORMAL); amanager.setBluetoothScoOn(false); super.onDestroy(); } } As you can see I tried combinations of various methods that I thought will fool the phone to believe my audio is a phone call: Using MediaPlayer's setAudioStreamType(STREAM_VOICE_CALL) using AudioManager's setBluetoothScoOn(true) using AudioManager's setMode(MODE_IN_CALL) But none of the above worked. If I remove the AudioManager calls in the above code, the audio plays from speaker and if I replace them as shown above then the audio stops coming from speakers, but it doesn't come through the BT headset. So this might be a partial success. I have checked that the BT headset works alright with phone calls. There must be a reason for Android not supporting this. But I can't let go of the feeling that it is not possible to programmatically reroute the audio. Any ideas? P.S. above code needs following permission <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS"/>

• MVVM load data during or after ViewModel construction?

  - by mkmurray

  My generic question is as the title states, is it best to load data during ViewModel construction or afterward through some Loaded event handling? I'm guessing the answer is after construction via some Loaded event handling, but I'm wondering how that is most cleanly coordinated between ViewModel and View? Here's more details about my situation and the particular problem I'm trying to solve: I am using the MVVM Light framework as well as Unity for DI. I have some nested Views, each bound to a corresponding ViewModel. The ViewModels are bound to each View's root control DataContext via the ViewModelLocator idea that Laurent Bugnion has put into MVVM Light. This allows for finding ViewModels via a static resource and for controlling the lifetime of ViewModels via a Dependency Injection framework, in this case Unity. It also allows for Expression Blend to see everything in regard to ViewModels and how to bind them. So anyway, I've got a parent View that has a ComboBox databound to an ObservableCollection in its ViewModel. The ComboBox's SelectedItem is also bound (two-way) to a property on the ViewModel. When the selection of the ComboBox changes, this is to trigger updates in other views and subviews. Currently I am accomplishing this via the Messaging system that is found in MVVM Light. This is all working great and as expected when you choose different items in the ComboBox. However, the ViewModel is getting its data during construction time via a series of initializing method calls. This seems to only be a problem if I want to control what the initial SelectedItem of the ComboBox is. Using MVVM Light's messaging system, I currently have it set up where the setter of the ViewModel's SelectedItem property is the one broadcasting the update and the other interested ViewModels register for the message in their constructors. It appears I am currently trying to set the SelectedItem via the ViewModel at construction time, which hasn't allowed sub-ViewModels to be constructed and register yet. What would be the cleanest way to coordinate the data load and initial setting of SelectedItem within the ViewModel? I really want to stick with putting as little in the View's code-behind as is reasonable. I think I just need a way for the ViewModel to know when stuff has Loaded and that it can then continue to load the data and finalize the setup phase. Thanks in advance for your responses.

• How to get attribute value using SelectSingleNode?

  - by Nano HE

  I am parsing a xml document, I need find out the gid (an attribute) value (3810). Based on SelectSingleNode(). I found it is not easy to find the attribute name and it's value. Can I use this method or I must switch to other way. Attached my code. How can I use book obj to get the attribute value3810 for gid. Thank you. My test.xml file as below <?xml version="1.0" ?> <root> <VersionInfo date="2007-11-28" version="1.0.0.2" /> <Attributes> <AttrDir name="EFEM" DirID="1"> <AttrDir name="Aligner" DirID="2"> <AttrDir name="SequenceID" DirID="3"> <AttrObj text="Slot01" gid="3810" unit="" scale="1" /> <AttrObjCount value="1" /> </AttrDir> </AttrDir> </AttrDir> </Attributes> </root> I wrote the test.cs as below public class Sample { public static void Main() { XmlDocument doc = new XmlDocument(); doc.Load("test.xml"); XmlNode book; XmlNode root = doc.DocumentElement; book = root.SelectSingleNode("Attributes[AttrDir[@name='EFEM']/AttrDir[@name='Aligner']/AttrDir[@name='SequenceID']/AttrObj[@text='Slot01']]"); Console.WriteLine("Display the modified XML document...."); doc.Save(Console.Out); } } [Update 06/10/2010] The xml file is a complex file. Included thousands of gids. But for each of Xpath, the gid is unique. I load the xml file to a TreeView control. this.treeView1.AfterSelect += new System.Windows.Forms.TreeViewEventHandler(this.treeView1_AfterSelect);. When treeView1_AfterSelect event occurred, the e.Node.FullPath will return as a String Value. I parse the string Value e.Node.FullPath. Then I got the member of XPath Above. Then I tried to find which gid item was selected. I need find the gid value as a return value indeed.
