    - by Kasun
    Hi, I try to convert text file to xml file using following code. But i get error in line 12. Could any one correct it and give me the correct answer. private void button1_Click(object sender, EventArgs e) { string[] lines = File.ReadAllLines("ex3.txt"); char[] ca = new char[] { '~' }; using (XmlTextWriter writer = new XmlTextWriter("ex3.xml", null)) { writer.Formatting = Formatting.Indented; writer.WriteStartDocument(); writer.WriteStartElement("Root"); writer.WriteStartElement("Header"); writer.WriteStartElement("H1"); writer.WriteString(lines[0].TrimEnd().Split(ca, 2)[1]); writer.WriteEndElement(); writer.WriteStartElement("H2"); writer.WriteString(lines[1].TrimEnd().Split(ca, 2)[1]); writer.WriteEndElement(); writer.WriteEndElement(); writer.WriteStartElement("Details"); for (int i = 2; i < lines.Length - 2; i++) { writer.WriteStartElement("D" + (i - 1).ToString()); writer.WriteString(lines[i].TrimEnd().Split(ca, 2)[1]); writer.WriteEndElement(); } writer.WriteEndElement(); writer.WriteStartElement("Footer"); writer.WriteStartElement("F1"); writer.WriteString(lines[lines.Length - 2].TrimEnd().Split(ca, 2)[1]); writer.WriteEndElement(); writer.WriteStartElement("F2"); writer.WriteString(lines[lines.Length - 1].TrimEnd().Split(ca, 2)[1]); writer.WriteEndElement(); writer.WriteEndElement(); writer.WriteEndDocument(); } } Thanks

  • Blob in Java/Hibernate/sql-server 2005

    - by Ramy
    Hi, I'm trying to insert an HTML blob into our sql-server2005 database. i've been using the data-type [text] for the field the blob will eventually live in. i've also put a '@Lob' annotation on the field in the domain model. The problem comes in when the HTML blob I'm attempting to store is larger than 65536 characters. Its seems that is the caracter-limit for a text data type when using the @Lob annotation. Ideally I'd like to keep the whole blob in tact rather than chunk it up into multiple rows in the database. I appreciate any help or insight that might be provided. Thanks! _Ramy Allow me to clarify annotation: @Lob @Column(length = Integer. MAX_VALUE) //per an answer on stackoverflow private String htmlBlob; database side (sql-server-2005): CREATE TABLE dbo.IndustrySectorTearSheetBlob( ... htmlBlob text NULL ... ) Still seeing truncation after 65536 characters... EDIT: i've printed out the contents of all possible strings (only 10 right now) that would be inserted into the Database. Each string seems to contain all cahracters, judging by the fact that the close html tag is present at the end of the string....

  • Active Directory login - DirectoryEntry inconsistent exception

    - by Pavan Reddy
    I need to validate the LDAP user by checking if there exists such a user name in the specified domain. For this I am using this code - DirectoryEntry entry = new DirectoryEntry("LDAP://" + strDomainController); DirectorySearcher searcher = new DirectorySearcher(entry); searcher.Filter = "SAMAccountName=" + strUserName; SearchResult result = searcher.FindOne(); return (result != null) ? true : false; This is a method in a class library which I intened to reference and use whereever I need this functionality in my project. To test this, I created a simple test application. The test occurs like this - Console.WriteLine(MyClassLib.MyValidateUserMethod("UserName", "Domain",ref strError).ToString()); The problem I am facing is that this works fine when I test it with my testapp but in my project, when I try to use the same method with the same credentials - The DirectoryEntry object throws an "System.DirectoryServices.DirectoryServicesCOMException" exception and the search.Filter fails and throws ex = {"Logon failure: unknown user name or bad password.\r\n"} exception. I have tried impersonation but that doesn't help. Somehow the same method works fine in mytestapp and doesn't work in my project. Both these applications are in my local dev machine. What am I missing? Any ideas?

  • OpenGL/Carbon/Cocoa Memory Management Autorelease issue

    - by Stephen Furlani
    Hoooboy, I've got another doozy of a memory problem. I'm creating a Carbon (AGL) Window, in C++ and it's telling me that I'm autorelease-ing it without a pool in place. uh... what? I thought Carbon existed outside of the NSAutoreleasePool... When I call glEnable(GL_TEXTURE_2D) to do some stuff, it gives me a EXC_BAD_ACCESS warning - but if the AGL Window is never getting release'd, then shouldn't it exist? Setting set objc-non-blocking-mode at (gdb) doesn't make the problem go away. So I guess my question is WHAT IS UP WITH CARBON/COCOA/NSAutoreleasePool? And... are there any resources for Objective-C++? Because crap like this keeps happening to me. Thanks, -Stephen --- CODE --- Test Draw Function void Channel::frameDraw( const uint32_t frameID) { eq::Channel::frameDraw( frameID ); getWindow()->makeCurrent(false); glEnable(GL_TEXTURE_2D); // Throws Error Here } Make Current (Equalizer API from Eyescale) void Window::makeCurrent( const bool useCache ) const { if( useCache && getPipe()->isCurrent( this )) return; _osWindow->makeCurrent(); } void AGLWindow::makeCurrent() const { aglSetCurrentContext( _aglContext ); AGLWindowIF::makeCurrent(); if( _aglContext ) { EQ_GL_ERROR( "After aglSetCurrentContext" ); } } _aglContext is a valid memory location (i.e. not NULL) when I step through. -S!

  • Launch User Control in a tab control dynamically

    - by Redburn
    I have a custom built menu system in which I would like to load user controls from another project into a tab control on my main project (menu control) User control Project : foobar Menu system Project : Menu The function to load them into the tab control: private void LaunchWPFApplication(string header, string pPath) { // Header - What loads in the tabs header portion. // pPath - Page where to send the user //Create a new browser tab object BrowserTab bt = tabMain.SelectedItem as BrowserTab; bt = new BrowserTab(); bt.txtHeader.Text = header; bt.myParent = BrowserTabs; //Load in the path try { Type formType = Type.GetType(pPath, true); bt.Content = (UserControl)Activator.CreateInstance(formType); } catch { MessageBox.Show("The specified user control : " + pPath + " cannot be found"); } //Add the browser tab and then focus BrowserTabs.Add(bt); bt.IsSelected = true; } And what I send to the function as an example: LaunchWPFApplication("Calculater", "foobar.AppCalculater"); But every time run, the application complains that the formType is null. I am confused on how to load the user control and curious if I'm sending the correct parameters.

  • Using Moq callbacks correctly according to AAA

    - by Hadi Eskandari
    I've created a unit test that tests interactions on my ViewModel class in a Silverlight application. To be able to do this test, I'm mocking the service interface, injected to the ViewModel. I'm using Moq framework to do the mocking. to be able to verify bounded object in the ViewModel is converted properly, I've used a callback: [Test] public void SaveProposal_Will_Map_Proposal_To_WebService_Parameter() { var vm = CreateNewCampaignViewModel(); var proposal = CreateNewProposal(1, "New Proposal"); Services.Setup(x => x.SaveProposalAsync(It.IsAny<saveProposalParam>())).Callback((saveProposalParam p) => { Assert.That(p.plainProposal, Is.Not.Null); Assert.That(p.plainProposal.POrderItem.orderItemId, Is.EqualTo(1)); Assert.That(p.plainProposal.POrderItem.orderName, Is.EqualTo("New Proposal")); }); proposal.State = ObjectStates.Added; vm.CurrentProposal = proposal; vm.Save(); } It is working fine, but if you've noticed, using this mechanism the Assert and Act part of the unit test have switched their parts (Assert comes before Acting). Is there a better way to do this, while preserving correct AAA order?

  • Masking FLV video in AS3 with PNG alpha channel.

    - by James Roberts
    Hey there, I'm trying to mask an FLV with a PNG alpha channel. I'm using BitmapData (from a PNG) but it's not working. Is there anything I'm missing? Cut up code below: var musclesLoader:Loader = new Loader(); var musclesContainer:Sprite = new Sprite(); var musclesImage:Bitmap = new Bitmap(); var musclesBitmapData:BitmapData; var musclesVideo:Video = new Video(752, 451.2); var connection:NetConnection = new NetConnection(); var stream:NetStream; function loadMuscles():void { musclesLoader.load(new URLRequest('img/muscles.png')); musclesLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, musclesComplete); } function musclesComplete():void { musclesBitmapData = new BitmapData(musclesLoader.content.width, musclesLoader.content.height, true, 0x000000); musclesImage.bitmapData = musclesBitmapData; musclesImage.smoothing = true; musclesContainer.addChild(musclesImage); contentContainer.addChild(musclesContainer); } function loadMusclesVideo():void { connection.connect(null); stream = new NetStream(connection); stream.client = this; musclesVideo.mask = musclesBitmapData; stage.addChild(musclesVideo); musclesVideo.attachNetStream(stream); stream.bufferTime = 1; stream.receiveAudio(true); stream.receiveVideo(true); stream.play("vid/muscles.flv"); } Outside this code I have a function that adds the containers to the stage, etc and places the objects in the appropriate spots. It sort of works - the mask applies, but in a square (the size of the boundaries of musclesBitmapData) rather than with the shape of the alpha channel. Is this the right way to go about this?

  • How to display image within cell boundary

    - by Jessy
    How can I place an image within the cell boundary? I mean without taking the space of other cell? In the code below, random cells were selected to display images. One image in one cell. The problem is that, the image seems to take other cells as well. ... setPreferredSize(new Dimension(600,600)); final int ROWS = 6; final int COLS = 6; final int IMAGES = 10; setLayout(new GridBagLayout()); GridBagConstraints gc = new GridBagConstraints(); gc.weightx = 1d; gc.weighty = 1d; gc.insets = new Insets(0, 0, 0, 0);//top, left, bottom, and right gc.fill = GridBagConstraints.NONE; JLabel[][] label = new JLabel[ROWS][COLS]; Random rand = new Random(); // fill the panel with labels for (int i=0;i<IMAGES;i++){ ImageIcon icon = createImageIcon("myImage.jpg"); int r, c; do{ //pick random cell which is empty to avoid overlap image in the same cell r = (int)Math.floor(Math.random() * ROWS); c = (int)Math.floor(Math.random() * COLS); } while (label[r][c]!=null); //scale the image int x = rand.nextInt(20)+30; int y = rand.nextInt(20)+30; Image image = icon.getImage().getScaledInstance(x,y, Image.SCALE_SMOOTH); icon.setImage(image); JLabel lbl = new JLabel(icon); gc.gridx = r; gc.gridy = c; add(lbl, gc); //add image to the cell label[r][c] = lbl; }

  • LINQ Datacontext Disposal Issues

    - by Refracted Paladin
    I am getting a Cannot access object: DataContext after it's been disposed in the below DAL method. I thought that I would be okay calling dispose there. result is an IEnumurable and I thought it was IQueryable that caused these kinds of problems. What am I doing wrong? How SHOULD I be disposing of my DataContext. Is there something better to be returning then a DataTable? This is a Desktop app that points at SQL 2005. Example method that causes this error -- public static DataTable GetEnrolledMembers(Guid workerID) { var DB = CmoDataContext.Create(); var AllEnrollees = from enrollment in DB.tblCMOEnrollments where enrollment.CMOSocialWorkerID == workerID || enrollment.CMONurseID == workerID join supportWorker in DB.tblSupportWorkers on enrollment.EconomicSupportWorkerID equals supportWorker.SupportWorkerID into workerGroup from worker in workerGroup.DefaultIfEmpty() select new { enrollment.ClientID, enrollment.CMONurseID, enrollment.CMOSocialWorkerID, enrollment.EnrollmentDate, enrollment.DisenrollmentDate, ESFirstName = worker.FirstName, ESLastName = worker.LastName, ESPhone = worker.Phone }; var result = from enrollee in AllEnrollees.AsEnumerable() where (enrollee.DisenrollmentDate == null || enrollee.DisenrollmentDate > DateTime.Now) //let memberName = BLLConnect.MemberName(enrollee.ClientID) let lastName = BLLConnect.MemberLastName(enrollee.ClientID) let firstName = BLLConnect.MemberFirstName(enrollee.ClientID) orderby enrollee.DisenrollmentDate ascending, lastName ascending select new { enrollee.ClientID, //MemberName = memberName, LastName = lastName, FirstName = firstName, NurseName = BLLAspnetdb.NurseName(enrollee.CMONurseID), SocialWorkerName = BLLAspnetdb.SocialWorkerName(enrollee.CMOSocialWorkerID), enrollee.EnrollmentDate, enrollee.DisenrollmentDate, ESWorkerName = enrollee.ESFirstName + " " + enrollee.ESLastName, enrollee.ESPhone }; DB.Dispose(); return result.CopyLinqToDataTable(); } partial class where I create the DataContext -- partial class CmoDataContext { public static bool IsDisconnectedUser { get { return Settings.Default.IsDisconnectedUser; } } public static CmoDataContext Create() { var cs = IsDisconnectedUser ?

  • Spring.net is not injecting chained base class properties!

    - by JohnIdol
    I am successfully injecting base class properties with spring.net with just a class that inherits from a base abstract class. Lets say Class MyClass : MyBase, and I am successfully setting a property like this: <object id="myInstantiableClass" type="myAssembly.MyClass myAssenbly" abstract="true"> <property name="MyBaseClassProperty" ref="anotherObjRef"></property> </object> Where MyBaseClassProperty is a property on the base class. Now I have another abstract class between the old base class and the instantiable class, and I am trying to set properties on both the abstract classes. So MyClass : MyNewBaseClass, and MyNewBaseClass : MyBaseClass. I have an additional property on the new base class (MyNewBaseClassProperty) and I am trying to inject it like this: <object id="myInstantiableClass" type="myAssembly.MyClass myAssenbly" abstract="true"> <property name="MyBaseClassProperty" ref="anotherObjRef"></property> <property name="MyNewBaseClassProperty" ref="someOtherObjRef"></property> </object> The property on the old base class is being injected but the one on the new one is not - and I am not getting an error or anything (so I am pretty sure my config is good), that property is just null! Any help appreciated! P.S. I am on asp.net (not MVC) but I don't think it's related.

  • Flash AS2.0 and JavaScript/jQuery (ExternalInterface) Communication

    - by abysslogic
    Hi there, Im trying to use JS to send data to my Flash AS2.0 music player with ExternalInterface, except there are no good tutorials or guides on ExternalInterface that I can find. I want to be able to change the current song in the player by clicking a JavaScript link, and on page / window load without clicking, play a default song. I dont need a super complicated answer on loading sounds in flash, etc., I am just having a lot of difficulties getting JS to send anything to Flash, and when I get that to work - would I need to put some if / else into the flash to determine if the link has been clicked or not? Thanks edit heres the code as of now: AS 2.0 import flash.external.ExternalInterface; ExternalInterface.addCallback('loadSong', null, flashFunction); function flashFunction (val) { extra = val; } JavaScript var flashObj = document.getElementById('VSPLAYER'); function loadSong(val) { return val } HTML <a href="javascript:loadSong('2')">Play song 2</a> <object id="VSPLAYER" type="application/x-shockwave-flash" data="vs_player.swf" width="280" height="90"> <param name="movie" value="vs_player.swf" /> <param name="allowscriptaccess" value="always" /> </object>

  • Broadcasting an intent to a specific component.

    - by Nic Strong
    I have an activity that is starting a background operation in another service. This activity receives various notifications from this service. As part of the intent I use to initiate the background operation I pass extra data with the context of my activity so the background service can broadcast intents back to me (the download service is a good example of this usage). So in the activity I use the following to attach the context: intent.putExtra(Intents.EXTRA_NOTIFICATION_PACKAGE, IntentTestActivity.this.getPackageName()); intent.putExtra(Intents.EXTRA_NOTIFICATION_CLASS, IntentTestActivity.class.getCanonicalName()); intent.putExtra(Intents.EXTRA_NOTIFICATION_EXTRAS, myContext); I register for the notifications in the activity: IntentFilter intentFilter = new IntentFilter(); intentFilter.addAction(Intents.ACTION_NOTIFICATION); intentFilter.addCategory(Intents.CATEGORY_COMPLETION); intentFilter.addCategory(Intents.CATEGORY_PROGRESSS); Intent intent = registerReceiver(receiver, intentFilter); In the background service I send notifications with the following code: void broadcastNotification(String action, String category, String packageName, String className, String extras, int operationResult) { Intent intent = new Intent(action); intent.addCategory(category); intent.setClassName(packageName, className); if (extras != null) { intent.putExtra(Intents.EXTRA_NOTIFICATION_EXTRAS, extras); } intent.putExtra(Intents.EXTRA_OPERATION_RESULT, operationResult); context.sendBroadcast(intent); } My problem is that the above broadcast will never be received. If however I comment out the line intent.setClassName(packageName, className); Then the broadcast is received. Is it a problem with my filter? Do I have to specify intents intended for a specific component? Or cannot I not use such fine grain control over the delivery of broadcasts. Thanks, Nic

  • Asp.Net Cache, modify an object from cache and it changes the cached value

    - by Glen
    Hi, I'm having an issue when using the Asp.Net Cache functionality. I add an object to the Cache then at another time I get that object from the Cache, modify one of it's properties then save the changes to the database. But, the next time I get the object from Cache it contains the changed values. So, when I modify the object it modifies the version which is contained in cache even though I haven't updated it in the Cache specifically. Does anyone know how I can get an object from the Cache which doesn't reference the cached version? i.e. Step 1: Item item = new Item(); item.Title = "Test"; Cache.Insert("Test", item, null, DateTime.Now.AddHours(1), System.Web.Caching.Cache.NoSlidingExpiration); Step 2: Item item = (Item)Cache.Get("test"); item.Title = "Test 1"; Step 3: Item item = (Item)Cache.Get("test"); if(item.Title == "Test 1"){ Response.Write("Object has been changed in the Cache."); } I realise that with the above example it would make sense that any changes to the item get reflected in cache but my situation is a bit more complicated and I definitely don't want this to happen.

  • How do I Unit Test Actions without Mocking that use UpdateModel?

    - by Hellfire
    I have been working my way through Scott Guthrie's excellent post on ASP.NET MVC Beta 1. In it he shows the improvements made to the UpdateModel method and how they improve unit testing. I have recreated a similar project however anytime I run a UnitTest that contains a call to UpdateModel I receive an ArgumentNullException naming the controllerContext parameter. Here's the relevant bits, starting with my model: public class Country { public Int32 ID { get; set; } public String Name { get; set; } public String Iso3166 { get; set; } } The controller action: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Edit(Int32 id, FormCollection form) { using ( ModelBindingDataContext db = new ModelBindingDataContext() ) { Country country = db.Countries.Where(c => c.CountryID == id).SingleOrDefault(); try { UpdateModel(country, form); db.SubmitChanges(); return RedirectToAction("Index"); } catch { return View(country); } } } And finally my unit test that's failing: [TestMethod] public void Edit() { CountryController controller = new CountryController(); FormCollection form = new FormCollection(); form.Add("Name", "Canada"); form.Add("Iso3166", "CA"); var result = controller.Edit(2 /*Canada*/, form) as RedirectToRouteResult; Assert.IsNotNull(result, "Expected to be redirected on successful POST."); Assert.AreEqual("Show", result.RouteName, "Expected to redirect to the View action."); } ArgumentNullException is thrown by the call to UpdateModel with the message "Value cannot be null. Parameter name: controllerContext". I'm assuming that somewhere the UpdateModel requires the System.Web.Mvc.ControllerContext which isn't present during execution of the test. I'm also assuming that I'm doing something wrong somewhere and just need to pointed in the right direction. Help Please!

  • SQL Query - group by more than one column, but distinct

    - by Ranhiru
    I have a bidding table, as follows: SellID INT FOREIGN KEY REFERENCES SellItem(SellID), CusID INT FOREIGN KEY REFERENCES Customer(CusID), Amount FLOAT NOT NULL, BidTime DATETIME DEFAULT getdate() Now in my website I need to show the user the current bids; only the highest bid but without repeating the same user. SELECT CusID, Max(Amount) FROM Bid WHERE SellID = 10 GROUP BY CusID ORDER BY Max(Amount) DESC This is the best I have achieved so far. This gives the CusID of each user with the maximum bid and it is ordered ascending. But I need to get the BidTime for each result as well. When I try to put the BidTime in to the query: SELECT CusID, Max(Amount), BidTime FROM Bid WHERE SellID = 10 GROUP BY CusID ORDER BY Max(Amount) DESC I am told that "Column 'Bid.BidTime' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause." Thus I tried: SELECT CusID, Max(Amount), BidTime FROM Bid WHERE SellID = 10 GROUP BY CusID, BidTime ORDER BY Max(Amount) DESC But this returns all the rows. No distinction. Any suggestions on solving this issue?

  • JPA - Setting entity class property from calculated column?

    - by growse
    I'm just getting to grips with JPA in a simple Java web app running on Glassfish 3 (Persistence provider is EclipseLink). So far, I'm really liking it (bugs in netbeans/glassfish interaction aside) but there's a thing that I want to be able to do that I'm not sure how to do. I've got an entity class (Article) that's mapped to a database table (article). I'm trying to do a query on the database that returns a calculated column, but I can't figure out how to set up a property of the Article class so that the property gets filled by the column value when I call the query. If I do a regular "select id,title,body from article" query, I get a list of Article objects fine, with the id, title and body properties filled. This works fine. However, if I do the below: Query q = em.createNativeQuery("select id,title,shorttitle,datestamp,body,true as published, ts_headline(body,q,'ShortWord=0') as headline, type from articles,to_tsquery('english',?) as q where idxfti @@ q order by ts_rank(idxfti,q) desc",Article.class); (this is a fulltext search using tsearch2 on Postgres - it's a db-specific function, so I'm using a NativeQuery) You can see I'm fetching a calculated column, called headline. How do I add a headline property to my Article class so that it gets populated by this query? So far, I've tried setting it to be @Transient, but that just ends up with it being null all the time.

  • PHP/Java Bridge - Access Java objects in PHP

    - by Omer Hassan
    I have a Red5 application which defines some public Java methods. When I start the server, an object of the application class gets created. I am trying to call the public methods of the application class from PHP using the existing instance of the Java application class. So here's my Java application: public class App extends org.red5.server.adapter.ApplicationAdapter { public boolean appStart(IScope app) { // This method gets called when the application starts // and an object of this App class is created. return true; } // This is the method I would like to call from PHP. public void f() { } } From PHP, I would like to get access to the App object that is created and call the method f() on it. I have tried playing around with this thing called "context". So in the Java method App.appStart(), I did this: // Save a reference to this App object to be retrieved later in PHP. new PhpScriptContextFactory().getContext().put("x", this); And in PHP, I tried to access the saved object like this: require_once("http://localhost:5080/JavaBridge/java/Java.inc"); var_dump(java_is_null(java_context()->get("x"))); Unfortunately, the java_is_null() function in PHP returns true. I also tried saving the App object in a static variable of App class but when I access that variable in PHP, its value is null.

  • When can a == b be false and a.Equals(b) true?

    - by alastairs
    I ran into this situation today. I have an object which I'm testing for equality; the Create() method returns a subclass implementation of MyObject. MyObject a = MyObject.Create(); MyObject b = MyObject.Create(); a == b; // is false a.Equals(b); // is true Note I have also over-ridden Equals() in the subclass implementation, which does a very basic check to see whether or not the passed-in object is null and is of the subclass's type. If both those conditions are met, the objects are deemed to be equal. The other slightly odd thing is that my unit test suite does some tests similar to Assert.AreEqual(MyObject.Create(), MyObject.Create()); // Green bar and the expected result is observed. Therefore I guess that NUnit uses a.Equals(b) under the covers, rather than a == b as I had assumed. Side note: I program in a mixture of .NET and Java, so I might be mixing up my expectations/assumptions here. I thought, however, that a == b worked more consistently in .NET than it did in Java where you often have to use equals() to test equality.

  • Flex: FileReference and Image unhandled IOErrorEvent

    - by deux11
    The following code shows a button that allows you to select a file (should be an image) and display it into an image component. When I select an invalid image (e.g. a word document), I get the following error: "Error #2044: Unhandled IOErrorEvent:. text=Error #2124: Loaded file is an unknown type." I know I can pass a FileFilter to the FileReference:browse call, but that's beyond the point. My question is... I want to handle the IOErrorEvent myself, what event listener am I missing? private var file:FileReference = new FileReference(); private function onBrowse():void { file.browse(null); file.addEventListener(Event.SELECT, handleFileSelect); file.addEventListener(Event.COMPLETE, handleFileComplete); } private function handleFileSelect(event:Event):void { file.load(); } private function handleFileComplete(event:Event):void { myImage.source = file.data; } private function handleImageIoError(evt:IOErrorEvent):void { Alert.show("IOErrorEvent"); } <mx:Button click="onBrowse()" label="Browse"/> <mx:Image id="myImage" width="100" height="100" ioError="handleImageIoError(event)"/>

  • .net mvc pass dictionary data from view to controller

    - by Wei Ma
    A while ago, I was trying to pass a dictionary data from my view to my controller. And I was able to do so after googling on the net(remember it was one of scott hanselman's posts). The solution I had was something like <%for(int index=0; index<Model.Count(); index++){ var property= Model.ElementAt(index);%> <input type="hidden" name="<%="properties["+index+"].Key"%>"/> <input type="hidden" name="<%="properties["+index+"].Value"%>"/> <%}%> public ActionResult Process(IDictionary<string,string> properties) { doSomething(); return View(); } The code worked for awhile and then I did some refactoring and got rid of this chunk of code. Today, I ran into a situation in which I would like to pass a dictionary again. But no matter how hard I try, the properties parameter received by the action was always null. I tried the above code and <%for(int index=0; index<Model.Count(); index++){ var property= Model.ElementAt(index);%> <input type="hidden" name="<%="properties.Keys["+index+"]"%>"/> <input type="hidden" name="<%="properties.Values["+index+"]"%>"/> <%}%> Neither code worked. I googled again but couldn't find the post that helped me before. Can someone point out what I did wrong? thanks a million.
