  • Keeping the DI-container usage in the composition root in Silverlight and MVVM

    - by adrian hara
    It's not quite clear to me how I can design so I keep the reference to the DI-container in the composition root for a Silverlight + MVVM application. I have the following simple usage scenario: there's a main view (perhaps a list of items) and an action to open an edit view for one single item. So the main view has to create and show the edit view when the user takes the action (e.g. clicks some button). For this I have the following code: public interface IView { IViewModel ViewModel {get; set;} } Then, for each view that I need to be able to create I have an abstract factory, like so public interface ISomeViewFactory { IView CreateView(); } This factory is then declared a dependency of the "parent" view model, like so: public class SomeParentViewModel { public SomeParentViewModel(ISomeViewFactory viewFactory) { // store it } private void OnSomeUserAction() { IView view = viewFactory.CreateView(); dialogService.ShowDialog(view); } } So all is well until here, no DI-container in sight :). Now comes the implementation of ISomeViewFactory: public class SomeViewFactory : ISomeViewFactory { public IView CreateView() { IView view = new SomeView(); view.ViewModel = ???? } } The "????" part is my problem, because the view model for the view needs to be resolved from the DI-container so it gets its dependencies injected. What I don't know is how I can do this without having a dependency to the DI-container anywhere except the composition root. One possible solution would be to have either a dependency on the view model that gets injected into the factory, like so: public class SomeViewFactory : ISomeViewFactory { public SomeViewFactory(ISomeViewModel viewModel) { // store it } public IView CreateView() { IView view = new SomeView(); view.ViewModel = viewModel; } } While this works, it has the problem that since the whole object graph is wired up "statically" (i.e. the "parent" view model will get an instance of SomeViewFactory, which will get an instance of SomeViewModel, and these will live as long as the "parent" view model lives), the injected view model implementation is stateful and if the user opens the child view twice, the second time the view model will be the same instance and have the state from before. I guess I could work around this with an "Initialize" method or something similar, but it doesn't smell quite right. Another solution might be to wrap the DI-container and have the factories depend on the wrapper, but it'd still be a DI-container "in disguise" there :) Any thoughts on this are greatly appreciated. Also, please forgive any mistakes or rule-breaking, since this is my first post on stackoverflow :) Thanks! ps: my current solution is that the factories know about the DI-container, and it's only them and the composition root that have this dependency.

  • Can I use UIRefreshControl with UICollectionViewScrollDirectionHorizontal?

    - by Dan Abramov
    You can add UIRefreshControl to UICollectionView (or any UIScrollView for that matter) by adding it to collection's subviews: UIRefreshControl *refreshControl = [[UIRefreshControl alloc] init]; [refreshControl addTarget:self action:@selector(handleRefresh:) forControlEvents:UIControlEventValueChanged]; [self.collectionView addSubview:refreshControl]; This doesn't work when collection view layout has UICollectionViewScrollDirectionHorizontal. I tried overriding layoutSubviews to put refresh control to the left, but it wouldn't track scrolling progress this way. Can I trick it into working with horizontal layouts?

  • Can't get tokens when using OAuth with LinkedIn API

    - by Angela
    Hi, was wondering if anyone can help me to get this basic OAuth implementation to work using the LinkedIn API: The output for the indexes oauth_token and oauth_token_secret are blank. The file I refer to in OAuth.php are a set of classes to help generate the token requests and tokens. That file is here: http://www.easy-share.com/1909603316/OAuth.php <?php session_start(); require_once("OAuth.php"); $app_token = "YOUR APP TOKEN GOES HERE"; $app_key = "YOUR APP KEY GOES HERE"; $domain = "https://api.linkedin.com/uas/oauth"; $sig_method = new OAuthSignatureMethod_HMAC_SHA1(); $test_consumer = new OAuthConsumer($app_token, $app_key, NULL); $callback = "http://".$_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF']."?action=getaccesstoken"; # First time through, get a request token from LinkedIn. if (!isset($_GET['action'])) { $req_req = OAuthRequest::from_consumer_and_token($test_consumer, NULL, "POST", $domain . "/requestToken"); $req_req->set_parameter("oauth_callback", $callback); # part of OAuth 1.0a - callback now in requestToken $req_req->sign_request($sig_method, $test_consumer, NULL); $ch = curl_init(); // make sure we submit this as a post curl_setopt($ch, CURLOPT_POSTFIELDS, ''); //New Line curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); curl_setopt($ch, CURLOPT_HTTPHEADER,array ( $req_req->to_header() )); curl_setopt($ch, CURLOPT_URL, $domain . "/requestToken"); curl_setopt($ch, CURLOPT_POST, 1); $output = curl_exec($ch); curl_close($ch); print_r($req_req); //<---- add this line print("$output\n"); //<---- add this line parse_str($output, $oauth); # pop these in the session for now - there's probably a more secure way of doing this! We'll need them when the callback is called. $_SESSION['oauth_token'] = $oauth['oauth_token']; $_SESSION['oauth_token_secret'] = $oauth['oauth_token_secret']; echo("token: " . $oauth['oauth_token']); echo("secret: " . $oauth['oauth_token_secret']); exit;

  • iPhone UIControl and Subview

    - by Jack Thompson
    I currently have a UIControl, which has a number of subviews (image, label). Unfortunately when I use addTarget etc. It doesn't detect touches on the subviews. [myCustomView addTarget:self action:@selector(touchedView:) forControlEvents:UIControlEventTouchUpInside]; Is it possible for the UIControl to detect touches on subviews or should i be approaching it differently.

  • Android Marketplace Error: "The server could not process your apk. Try again."

    - by jdandrea
    I have an updated apk - tested successfully on various devices and simulator instances - with the following manifest: <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.myCompany.appName" android:versionCode="2" android:versionName="1.0.1"> <uses-sdk android:minSdkVersion="3" android:targetSdkVersion="5" /> <uses-permission android:name="android.permission.INTERNET" /> <supports-screens android:largeScreens="true" android:normalScreens="true" android:smallScreens="true" /> <application android:icon="@drawable/icon" android:label="@string/icon_name" android:debuggable="false"> <activity android:name=".myActivity" android:configChanges="keyboardHidden|orientation"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> </manifest> When I post to Android Marketplace as an upgrade to my existing 1.0 app, I get the aforementioned ambiguous message: "The server could not process your apk. Try again." I've searched elsewhere for this message in hopes of finding out what might be happening, to no avail. (A popular suggestion is to move the uses-sdk element to the top of the manifest, but as you can see it's already at the top.) Clues welcome/appreciated. Update: I just tried to upload the same file again. Now I get a new message: The new apk's versionCode (2) in AndroidManifest.xml must be higher than the old apk's versionCode (2). The server could not process your apk. Try again. Soooo Marketplace did get my upgraded apk after all? (The very first accepted apk's versionCode was 1, so this update was of course bumped to 2.) Confused … Bumping it up to 3 and trying again. Surprise surprise, I get the original "could not process" error all over again. Going in circles. Hmm ... :( Nuther Update: If I exit and re-enter the Marketplace page, now it shows that the app has been uploaded! Except there's no app icon. Curiouser and curiouser ... and this is all happening with a cache-cleared (standards-friendly) browser to boot. So - do I trust the upload? Or start over ... with versionCode="4"? All I want is to get a solid "Upload successful, here's the icon, ready to publish" type of response.

  • I keep on getting "save operation failure" after any change on my XCode Data Model

    - by Philip Schoch
    I started using Core Data for iPhone development. I started out by creating a very simple entity (called Evaluation) with just one string property (called evaluationTopic). I had following code for inserting a fresh string: - (void)insertNewObject { // Create a new instance of the entity managed by the fetched results controller. NSManagedObjectContext *context = [fetchedResultsController managedObjectContext]; NSEntityDescription *entity = [[fetchedResultsController fetchRequest] entity]; NSManagedObject *newManagedObject = [NSEntityDescription insertNewObjectForEntityForName:[entity name] inManagedObjectContext:context]; // If appropriate, configure the new managed object. [newManagedObject setValue:@"My Repeating String" forKey:@"evaluationTopic"]; // Save the context. NSError *error; if (![context save:&error]) { // Handle the error... } [self.tableView reloadData]; } This worked perfectly fine and by pushing the +button a new "My Repeating String" would be added to the table view and be in persistent store. I then pressed "Design - Add Model Version" in XCode. I added three entities to the existing entity and also added new properties to the existing "Evaluation" entity. Then, I created new files off the entities by pressing "File - New File - Managed Object Classes" and created a new .h and .m file for my four entities, including the "Evaluation" entity with Evaluation.h and Evaluation.m. Now I changed the model version by setting "Design - Data Model - Set Current Version". After having done all this, I changed my insertMethod: - (void)insertNewObject { // Create a new instance of the entity managed by the fetched results controller. NSManagedObjectContext *context = [fetchedResultsController managedObjectContext]; NSEntityDescription *entity = [[fetchedResultsController fetchRequest] entity]; Evaluation *evaluation = (Evaluation *) [NSEntityDescription insertNewObjectForEntityForName:[entity name] inManagedObjectContext:context]; // If appropriate, configure the new managed object. [evaluation setValue:@"My even new string" forKey:@"evaluationSpeechTopic"]; // Save the context. NSError *error; if (![context save:&error]) { // Handle the error... } [self.tableView reloadData]; } This does not work though! Every time I want to add a row the simulator crashes and I get the following: "NSInternalInconsistencyException', reason: 'This NSPersistentStoreCoordinator has no persistent stores. It cannot perform a save operation.'" I had this error before I knew about creating new version after changing anything on the datamodel, but why is this still coming up? Do I need to do any mapping (even though I just added entities and properties that did not exist before?). In the Apple Dev tutorial it sounds very easy but I have been struggling with this for long time, never worked after changing model version.

  • ASP.NET MVC Consume JSONResult in Bing Maps API

    - by rockinthesixstring
    I know there are a few topics on this, but I seem to be fumbling my way through with no results. I'm trying to use a controller to return JSON results to my Bin Maps functions. Here's what I have for my controller (yes it is properly returning JSON data. Function Regions() As JsonResult Dim rj As New List(Of RtnJson)() rj.Add(New RtnJson("135 Bow Meadows Drive, Cochrane, Alberta", "desc", "title")) rj.Add(New RtnJson("12 Bowridge Dr NW, Calgary, Alberta, Canada", "desc2", "title2")) Return Json(rj, JsonRequestBehavior.AllowGet) End Function Then in my script I have this, but it's not working. <script type="text/javascript"> var map = null; var centerLat = 51.045 ; var centerLon = -114.05722; var json_object = $.getJSON("<%: Url.Action("Regions", "Events")%>"); function LoadMap() { map = new VEMap('bingMap'); map.LoadMap(new VELatLong(centerLat, centerLon), 10); $.each(json_object, function () { alert(this.address); //this alert is returning "address is undefined" StartGeocoding(this.address, this.title, this.desc); }); } function StartGeocoding(address, title, desc) { map.Find(null, // what address, // where null, // VEFindType (always VEFindType.Businesses) null, // VEShapeLayer (base by default) null, // start index for results (0 by default) null, // max number of results (default is 10) null, // show results? (default is true) null, // create pushpin for what results? (ignored since what is null) true, // use default disambiguation? (default is true) false, // set best map view? (default is true) GeocodeCallback); // call back function } function GeocodeCallback(shapeLayer, findResults, places, moreResults, errorMsg) { var bestPlace = places[0]; // Add pushpin to the *best* place var location = bestPlace.LatLong; var newShape = new VEShape(VEShapeType.Pushpin, location); var desc = "Latitude: " + location.Latitude + "<br>Longitude:" + location.Longitude; newShape.SetDescription(desc); newShape.SetTitle(bestPlace.Name); map.AddShape(newShape); } $(document).ready(function () { LoadMap(); }); </script>
