  • jQuery UI: Dialog button styling

    - by Peter Bridger
    Is there an easy way to apply CSS/icons to the modal buttons on a jQuery UI modal dialog box? If I include the HTML to display an icon with the button text, it shows the HTML as text rather than rendering the code. I'm guessing I could write some jQuery to find the button and overwrite the HTML with what I want, but I'm hoping there's an easier more direct way.

  • Avoiding mass propagation of properties and events for exposure to ViewModels.

    - by firoso
    I have an MVVM application I am developing that is to the point where I'm ready to start putting together a user interface (my client code is largely functional) I'm now running into the issue that I'm trying to get my application data to where I need it so that it can be consumed by the view model and then bound to the view. Unfortunately, it seems that I've either got a few structural oversights, or I'm just going to have to face the reality that I need to be propogating events and raising excessive amounts of errors to notify view models that thier properties have changed. Let me go into some examples of my issue: I have a class "Unit" contained in a class "Test", contained in a class "Session" contained in a class "TestManager" which is contained in "TestDataModel" which is utilized by "TestViewModel" which is databound to by my "TestView" .... WHOA. Now, consider that Unit (the bottom of the heiarchy) has a property called "Results" that is updated periodically, I want to expose that to my viewmodel and then databind it to my view, trouble is, the only way I can really think to do this is to perpetuate events WAY up a chain that say "I've been updated!" and then request the new value... This seems like an aweful way to do this. Alternatively, I could register a static event and raise it, and have the appropriate "Unit view model" grab the event and request the update. This SEEMS better... but... static events? Is that a taboo idea? Also, having an expression like: TestDataModel.TestManager.Session.Test.Unit.Results[i] Seems REALLY gross to have on a View Model. I know this all reeks of a bad design issue, but I can't figure out what I did wrong? Should I be using more singleton/container controlled lifetimes type objects? Register object instances with static helper containers? Obviously these are hard questions to answer without being intimate with the existing structure, but if you've run into situations like this, what did you do to refactor? Should I just live with this, add mass events, and propogate them?

  • A c# Generics question involving Controllers and Repositories

    - by UpTheCreek
    I have a base repository class which contains all the common repository methods (as generic): public abstract class BaseRepository<T, IdType> : IBaseRepository<T, IdType> My repositories from this base e.g.: public class UserRepository : BaseRepository<User, int>, IUserRepository I also have a base controller class containing common actions, and inherit from this in controllers. The repository is injected into this by DI. E.g. public class UserController : BaseController<User> { private readonly IUserRepository userRepository; public UserController (IUserRepository userRepository) { this.userRepository= userRepository; } My question is this: The base controller needs to be able to access the repository methods that are defined in the base repository. However I'm passing in via DI a different repository type for each controller (even though they all inherrit from the base repository). How can the base controller somehow access the repository that is passed in (regardless of what type it is), so that it can access the common base methods?

  • Setting synthesized arrays causing memory leaks using nested arrays

    - by webtoad
    Hello: Why is the following code causing a memory leak in an iPhone App? All of the initted objects below leak, including the arrays, the strings and the numbers. So, I'm thinking it has something to do with the the synthesized array property not releasing the object when I set the property again on the second and subsequent time this piece of code is called. Here is the code: "controller" (below) is my custom view controller class, which I have a reference to, and I am setting with this code snippet: sqlite3_stmt *statement; NSMutableArray *foo_IDs = [[NSMutableArray alloc] init]; NSMutableArray *foo_Names = [[NSMutableArray alloc] init]; NSMutableArray *foo_IDsBySection = [[NSMutableArray alloc] init]; NSMutableArray *foo_NamesBySection = [[NSMutableArray alloc] init]; // Get data: NSString *sql = @"select distinct p.foo_ID, p.foo_Name from foo as p "; if (sqlite3_prepare_v2(...) == SQLITE_OK) { while (sqlite3_step(statement) == SQLITE_ROW) { int p_id; NSString *foo_Name; p_id = sqlite3_column_int(statement, 0); char *str2 = (char *)sqlite3_column_text(statement, 1); foo_Name = [NSString stringWithCString:str2]; [foo_IDs addObject:[NSNumber numberWithInt:p_id]]; [foo_Names addObject:foo_Name]; } sqlite3_finalize(statement); } // Pass the array itself into another array: // (normally there is more than one array in each array) [foo_IDsBySection addObject: foo_IDs]; [foo_NamesBySection addObject: foo_Names]; [foo_IDs release]; [foo_Names release]; // Set some synthesized properties (of type NSArray, nonatomic, // retain) in controller: controller.foo_IDsBySection = foo_IDsBySection; controller.foo_NamesBySection = foo_NamesBySection; [foo_IDsBySection release]; [foo_NamesBySection release]; Thanks for any help!

  • Simple ASP.NET MVC Routing question

    - by Robert
    Hi there, I have two pages in my simple MVC App with two defined routes: routes.MapRoute( "Results", // Route name "Results/{id}", // URL with parameters new { controller = "Results", action = "Index", id = "" } // Parameter defaults ); routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Main", action = "Index", id = UrlParameter.Optional } // Parameter defaults ); I needed to have the results page load with just a product ID such as this: [MyDomain....]/Results/12345. But also the main page does a POST (using JQuery) to the Results Controller for updates using this route: [MyDomain....]/Main/Update along with a data bag. This works fine when I only have the "Default" route. But when I added the other "Results" route, all the POST calls to update are failing. Any ideas what I'm doing wrong??? Thanks a lot.

  • Dataset and Hierarchial Data How to Sort

    - by mdjtlj
    This is probably a dumb question, but I've hit a wall with this one at this current time. I have some data which is hierarchial in nature which is in an ADO.NEt dataset. The first field is the ID, the second is the Name, the third is the Parent ID. ID NAME Parent ID 1 Air Handling NULL 2 Compressor 1 3 Motor 4 4 Compressor 1 5 Motor 2 6 Controller 4 7 Controller 2 So the tree would look like the following: 1- Air Handling 4- Compressor 6 - Controller 3 - Motor 2- Compressor 7- Controller 5 - Motor What I'm trying to figure our is how to get the dataset in the same order that ths would be viewed in a treeview, which in this case is the levels at the appropriate levels for the nodes and then the children at the appropriate levels sorted by the name. It would be like binding this to a treeview and then simply working your way down the nodes to get the right order. Any links or direction would be greatly appreciated.

  • Need an advice for unit testing using mock object

    - by Andree
    Hi there, I just recently read about "Mocking objects" for unit testing and currently I'm having a difficulties implementing this approach in my application. Please let me explain my problem. I have a User model class, which is dependent on 2 data sources (database and facebook web service). The controller class simply use this User model as an interface to access data and it doesn't care about where the data came from. Currently I never done any unit test to this User model because it is dependent on an external web service. But just a while ago, I read about object mocking and now I know that it is a common approach to unit test a class that depends on external resources (like in my case). Now I want to create a unit test for the User model, but then I encountered a design issue: In order for the User model to use a mocked Facebook SDK, I have to inject this mocked Facebook SDK to the User object (probably using a setter). Therefore I can't construct the Facebook SDK inside the User object. I have to construct it outside the User object, and inject the SDK into the User object. The real client of my User model is the application's controller. Therefore I have to construct the Facebook SDK inside the controller and inject it to the user object. Well, this is a problem because I want my controller to be as clean as possible. I want my controller to be ignorant about the application's data source. I'm not good at explaining something systematically, so you'll probably sleeping before reading this last paragraph. But anyway, I want to ask if anyone here ever encountered the same problem as mine? How do you solve this problem? Regards, Andree

  • Animation of UINavigationController's UIToolbar

    - by Michael Waterfall
    When presenting a view controller that has toolbar items, is it possible for the toolbar to slide in with the view controller (i.e. slide in from the right) as opposed to it sliding from the bottom? In the view controller that is being presented, I've got the toolbar being shown within the -viewWillAppear: method, but the toolbar is being slid up from the bottom of the screen as opposed to it looking like it belongs to the view controller. - (void)viewWillAppear:(BOOL)animated { [self.navigationController setToolbarHidden:NO animated:YES]; ... }

  • Weird exception: Cannot cast String to Boolean when using getBoolean

    - by La bla bla
    I'm getting a very weird error. I have 2 activities. On both I'm getting the SharedPreferences using MODE_PRIVATE (if it matters) by sp = getPreferences(MODE_PRIVATE); on each activity's onCreate() I'm calling sp.getBoolean(IntroActivity.SHOW_INTRO, true) On the IntroActivity this works fine. But when I'm trying in the main activity, I'm getting this 10-12 04:55:23.208: E/AndroidRuntime(11668): FATAL EXCEPTION: main 10-12 04:55:23.208: E/AndroidRuntime(11668): java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Boolean 10-12 04:55:23.208: E/AndroidRuntime(11668): at android.app.SharedPreferencesImpl.getBoolean(SharedPreferencesImpl.java:242) 10-12 04:55:23.208: E/AndroidRuntime(11668): at com.lablabla.parkme.ParkMeActivity$2.onClick(ParkMeActivity.java:194) 10-12 04:55:23.208: E/AndroidRuntime(11668): at android.view.View.performClick(View.java:4084) 10-12 04:55:23.208: E/AndroidRuntime(11668): at android.view.View$PerformClick.run(View.java:16966) 10-12 04:55:23.208: E/AndroidRuntime(11668): at android.os.Handler.handleCallback(Handler.java:615) 10-12 04:55:23.208: E/AndroidRuntime(11668): at android.os.Handler.dispatchMessage(Handler.java:92) 10-12 04:55:23.208: E/AndroidRuntime(11668): at android.os.Looper.loop(Looper.java:137) 10-12 04:55:23.208: E/AndroidRuntime(11668): at android.app.ActivityThread.main(ActivityThread.java:4745) 10-12 04:55:23.208: E/AndroidRuntime(11668): at java.lang.reflect.Method.invokeNative(Native Method) 10-12 04:55:23.208: E/AndroidRuntime(11668): at java.lang.reflect.Method.invoke(Method.java:511) 10-12 04:55:23.208: E/AndroidRuntime(11668): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:786) 10-12 04:55:23.208: E/AndroidRuntime(11668): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:553) 10-12 04:55:23.208: E/AndroidRuntime(11668): at dalvik.system.NativeStart.main(Native Method) I made sure that I'm not putting a String somewhere in the middle with that same key Any ideas?

  • ASP.NET MVC - hiding id in URL?

    - by mcfroob
    I'm building a basic blog application just now, for viewing data I'm just using the default route, i.e. - routes.MapRoute ( "Default", // Route name "{controller}/{action}/{id}", new { controller = "Blog", action = "Index", id = UrlParameter.Optional } ); So that when you go to mysite.com/View/12 it displays the blog with id 12. I want to modify the URLs so that they look as follows: mysite.com/View/2010/06/01/this-is-the-title. I could have a URL mapping like - routes.MapRoute( "View", "View/{year}/{month}/{day}/{title}", new { controller = "Blog", action = "View" } ); But then I'm not passing the ID into the Controller action so I would have to search on the date and title which doesn't feel right. On the other hand, if I pass the ID in it will show up in the URL which isn't what I'm aiming for either. Is there any way to redirect to the URL I want in the controller action after passing only the ID in as a paramter, or to pass the ID into the a Map Route but hide it in the URL? Thanks for your help!

  • .NET MVC: How to fix Visual Studio's lack of awareness of CSS classes in partial views?

    - by Mega Matt
    Hi all, This has been sort of an annoyance for me for a while. I make pretty heavy use of partial views in MVC, and am using Visual Studio 2008 to develop. The problem is that when I give html elements a class in a partial view (<div class="someClass">), it will underline them in green like it doesn't know what they are. I realize this is because I'm in a partial view, and haven't put link tags anywhere in that file for it to know where the CSS is (the link tags are in the main view that renders the partial view). The CSS still works fine on my site because the browser will render all views as one long html page anyway, but it's really annoying to look through my partial views and see all of my classes underlined in green. Is there a way that I can still tell Visual Studio that those classes exist somewhere, from the partial view? I figured there has to be a way to let it know, but am not sure what it is. Maybe a way to import the stylesheets from the parent view? Thanks for your help.

  • iPhone SDK 3.0 deprecation of UITableViewCell .text

    - by djt9000
    Came across an SDK3.0 deprecation that I am having a bit of trouble tryinig to figure out. If my declaration of @property (nonatomic, retain) UIImage *rowImage; does not work, nor @property (nonatomic, readonly, retain) UIImage *rowImage; and I @synthesize rowImage; Do I need to write my own setter because @synthesize will not properly handle this? cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:RootViewControllerCell] autorelease]; // Dpericated in SDK 3.0 // //cell.text = controller.title; //cell.image = controller.rowImage; // Using what the documentation says to use Error=== cell.textLabel = controller.title; Error=== cell.imageView = controller.rowImage; Error: Object cannot be set - Either readonly property or no setter found. Hope this makes sense, any help would be appreciated.

  • How Does a Login system generally work with OOP?

    - by fakingfantastic
    Sorry if this is a badly formed question, but I'm trying to make my web applications (using PHP) more OO. *EDIT* I'm developing the Framework myself */EDIT* Everything is great so far, I've made a Front Controller system that taps into a MVC system. The FC figures out what page you want, loads the specific page Controller (*EDIT* which extends an abstract Controller Object */EDIT*), which gets anything it needs from Models, and then calls the appropriate View. Very basic. But now, I need to make an admin section (quasi-CMS). How does a login system fit into the grand scheme of things? Do you set controllers as needing a login? If so, how? What If you only want certain views of a controller requiring login? Thanks in advance.

  • AngularJS - $routeParams Empty on $locationChangeSuccess

    - by Marc M.

  • Knowing which annotation is selected and accessing properties of it.

    - by kevin Mendoza
    So far my program can display a database of custom annotation views. Eventually I want my program to be able to display extra information after a button on the annotation bubble is clicked. Each element in the database has a unique entry Number, so I thought it would be a good idea to add this entry number as a property of the custom annotation. The problem I am having is that after the button is clicked and the program switches to a new view I am unable to retrieve the entry number of the annotation I selected. Below is the code that assigns the entry Number property to the annotation: for (id mine in mines) { workingCoordinate.latitude = [[mine latitudeInitial] doubleValue]; workingCoordinate.longitude = [[mine longitudeInitial] doubleValue]; iProspectAnnotation *tempMine = [[iProspectAnnotation alloc] initWithCoordinate:workingCoordinate]; [tempMine setTitle:[mine mineName]]; [tempMine setAnnotationEntryNumber:[mine entryNumber]]; } [mines dealloc]; When the button on an annotation is selected, this is the code that initializes the new view: - (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control { mineInformationController *controller = [[mineInformationController alloc] initWithNibName:@"mineInformationController" bundle:nil]; controller.modalTransitionStyle = UIModalTransitionStyleCrossDissolve; [self presentModalViewController:controller animated:YES]; [controller release]; } and lastly is my attempt at retrieving the entryNumber property from the new view so that I can compare it to the mines database and retrieve more information on the array element. iProspectFresno_LiteAppDelegate *appDelegate = (iProspectFresno_LiteAppDelegate *)[[UIApplication sharedApplication] delegate]; NSMutableArray* mines = [[NSMutableArray alloc] initWithArray:(NSMutableArray *)appDelegate.mines]; for(id mine in mines) { if ([[mine entryNumber] isEqualToNumber: /*the entry Number of the selected annotation*/]) { /* display the information in the mine object */ } } So how do I access this entry number property in this new view controller?

  • How to call a method from another class that's been instantiated within the current class

    - by Pavan
    my screen has a few views like such __________________ | _____ | | | | | //viewX is a video screen | | | | | viewX | vY | | //viewY is a custom uiview i created. | |____| | //it contains a method which i would like to call that toggles |_________________| //the hidden property of this view. and when it hides, a little | | //button is replaced no the top right corner on top of viewX | viewZ | //the video layer | | |_________________| //viewZ is a view containing many square views - thumbnails. my question is, i dont know how to register for touch events so that it recognises any touch event on no matter which view the user touches the screen.. atm im handling the touch events for each view inside it. so all works well... however what im trying to do is that when the user taps anywhere else on the screen but on viewY, viewY should dissapear by calling that method in the viewY class. this viewY class is instantiated and has no xib file attached to it. the uiview is created progammatically in the viewY class. this whole class for viewY behviour is instantiated in viewX - the video view. my boss says add delegates.. although i have now clue how to do that... any help? is there anyway i can just make it really simple and be able to say REMOVE VIEW no matter which class im calling from? Also ive seen other people achieve this by using these funky arrows - ... <- etc.. although im not sure if thats what i need or how to implement such a thing. ah i think ive made my question quite complicated but i really mean it to be a simple one, and know it can be done in an easy way!

  • ServiceStack razor default page

    - by Tom
    Say I have 2 pages /NotADefault.cshtml /Views/Default.cshtml Question 1. Now I run it, page A always gets called implicitly as start-up default page no matter what I name it. Page B will only be called when I explicitly call localhost/View/Default. How do I make page B (the one in View folder) my default page? Question 2. I also have NotADefaultService.cs and DefaultService.cs. I give each page a Service class at the back. However, when page A is called NotADefaultService.cs never gets called. Only DefaultService.cs gets called when page B is called... My observation is that only the pages in the View folder will get their back-end service class working. Outside of View folder it doesn't work. Combining Q1 and Q2. How do I: Option 1. get the backend service class working under / root outside "View" folder? OR Option 2. appoint /View/Default.schtml as my default at start-up where the service class can be hit?

  • Spring+JSP url building best practices

    - by dotsid
    I wonder if there are any good practices for addressing Spring controllers in JSP. Suppose I have controller: @Controller class FooController { // Don't bother about semantic of this query right now @RequestMapping("/search/{applicationId}") public String handleSearch(@PathVariable String applicationId) { [...] } } Of course in JSP I can write: <c:url value="/search/${application.id}" /> But it's very hard to change url then. If you familiar with Rails/Grails then you now how this problem resolved: redirect_to(:controller => 'foo', :action = 'search') But in Spring there is so much UrlMappers. Each UrlMapper have own semantic and binding scheme. Rails alike scheme simply doesn't work (unless you implement it yourself). And my question is: are there any more convenient ways to address controller from JSP in Spring?

  • Random number generation in MVC applications

    - by SlimShaggy
    What is the correct way of generating random numbers in an ASP.NET MVC application if I need exactly one number per request? According to MSDN, in order to get randomness of sufficient quality, it is necessary to generate multiple numbers using a single System.Random object, created once. Since a new instance of a controller class is created for each request in MVC, I cannot use a private field initialized in the controller's constructor for the Random object. So in what part of the MVC app should I create and store the Random object? Currently I store it in a static field of the controller class and lazily initialize it in the action method that uses it: public class HomeController : Controller { ... private static Random random; ... public ActionResult Download() { ... if (random == null) random = new Random(); ... } } Since the "random" field can be accessed by multiple instances of the controller class, is it possible for its value to become corrupted if two instances attempt to initialize it simultaneously? And one more question: I know that the lifetime of statics is the lifetime of the application, but in case of an MVC app what is it? Is it from IIS startup till IIS shutdown?
