  • Load view when button is clicked in Xcodes Storyboard

    - by dooonot
    I just started to use Storyboard in Xcode. I have a starting view that has some buttons inside. Is there a way to load a special view when a button is clicked? I only found this workaround: -(IBAction)loadRegistration:(id)sender { // load registration controller UIStoryboard *storyboard = self.storyboard; RegisterController *svc = [storyboard instantiateViewControllerWithIdentifier:@"RegisterController"]; [self presentViewController:svc animated:YES completion:nil]; }

  • SilverLight 4 - How to have Buttons to switch between view in grid

    - by cvoeller
    I‘m trying to create a page with Silver Light 4, that is similar in functionality to the main page at the Silver Light Showcase website (http://www.silverlight.net/showcase/). Essentially I want to have buttons that change the view of the data in a Grid. One view might have just an image, another might have a smaller image with a smattering of data, and the third would be all the details. I wondering if anyone has a recommendation of how to achieve this?

  • Creating multiple objects of a view defined in the xml

    - by user362953
    I have to dynamically add a list of views (the views use RelativeLayout). Can I do this by specifying the view definition in xml and instantiate multiple objects off it? This gives the usual benefits of separating the view part from the code (for e.g., making it easy for the UI guys to alter things) or Is going the ArrayAdapter the suggested/only route?

  • Permission to view, but not to change! - Django

    - by RadiantHex
    Hi folks, is it possible to give users the permission to view, but not to change or delete. currently in the only permissions I see are "add", "change" and "delete"... but there is no "read/view" in there. I really need this as some users will only be able to consult the admin panel, in order to see what has been added in. Help would be amazing!

  • Animation in a table view cell

    - by theomen
    I'm not sure if it is possible to achieve, but my costumer wants that when user taps a table view cell, an animation of a UIView sliding from left to right is committed, leaving the content under the UIView visible. My concern is about how to trigger gesture recognizer added to the upper UIVIew for the animation and do not enter in conflict with didSelectRowatIndex: table view delegate method. Is it possible to achieve? Mant thanks!

  • Popping a modal view from anywhere in code

    - by ConfusedNoob
    Is it possible to 'pop' a view from any point in an iOS application. For example, I want an event to trigger a view sliding in (modal) and the event can happen at any time, on any screen in the application. Also, we'd like this to be something that can be included in other projects and would prefer them not to have to do anything special to these projects (other than wire in the referenced project).

  • Formtastic nested model form fields (Rails 3)

    - by elsurudo
    So here's the scenario: User: has_one :company accepts_nested_attributes_for :company Controller: @user = User.new @user.build_company View: <% semantic_form_for @user, :url => register_path do |form| %> <h2>User Information</h2> <%= form.inputs %> <h2>Company Information</h2> <% form.semantic_fields_for :company do |company| %> <%= company.inputs %> <% end %> <%= form.buttons %> <% end %> After scouring the web, this SEEMS like it should work. However, all I get are the user inputs. The "semantic_fields_for :company" block outputs nothing at all... Am I missing something here, or is this perhaps a Rails 3 bug to do with Formtastic?

  • ASP.NET MVC Model Binding

    - by Noel
    If i have a Controller Action that may recieve both HTTP GET and HTTP POST from a number of different sources with each source sending different data e.g. Source1 performs a form POST with two form items Item1 and Item2 Source2 performs a GET where the data is contained in the query string (?ItemX=2&ItemY=3) Is it possible to have a controller action that will cater for all these cases and perform binding automatically e.g. public ActionResult Test(Dictionary data) { // Do work ... return View(); } Is this possible with a custom binder or some other way? Dont want to work directly with HttpContext.Request if possible

  • ASP.NET MVC ,Maintaining Model State between Ajax requests

    - by Podders
    problem: On first full page request, my controller invokes an applicationServices Layer (Web Service Proxy to my business tier) in order to populate a collection of current services that is stored in my own controller base class property. This is then to be displayed within a view. Everything within the context of that controller has access to this "Services Collection". Now when i make further calls to the same action method via an AJAX Call, i obviously hitt a different instance of that controller meaning my services collection is empty. So other than re-getting the whole collection again, where would i store this collection so it gets persisted between ajax requests? Should i persist it as a seperate DomainModel Object, Session object?....as ViewData is not working for me obv. Excuse my MVC ignorance :) Any help would be greatly appreciated :)

  • ASP.NET MVC Access model data in masterpage

    - by Paul
    I have created a UserSiteBaseController that gets commonly used data and sets the data to a UserSiteBaseViewData viewmodel in a method called SetViewData public T CreateViewData<T>() where T : UserSiteBaseViewData, new() { .... } I then create specific Controllers that inherit from the UserSiteBaseController as well as viewModels that inherit from UserSiteHomeViewData and can be created in the controller like so: public ActionResult Index(string slug) { Slug = slug; var viewData = CreateUserSiteHomeViewData<UserSiteHomeViewData>(); //If invalid slug - throw 404 not found if (viewData == null) return PageNotFound(); viewData.Announcements = _announcementsData.All(slug).ToList(); return View(viewData); } private T CreateUserSiteHomeViewData<T>() where T : UserSiteHomeViewData, new() { T viewData = CreateViewData<T>(); return viewData; } The UserBaseViewData holds data that needs to be use on every page so it would be great to be able to access this data from the Masterpage in a strongly typed manner. Is this possible or am I going about this in the incorrect manner?

  • Entity Framework with MySQL - Timeout Expired while Generating Model

    - by Nathan Taylor
    I've constructed a database in MySQL and I am attempting to map it out with Entity Framework, but I start running into "GenerateSSDLException"s whenever I try to add more than about 20 tables to the EF context. An exception of type 'Microsoft.Data.Entity.Design.VisualStudio.ModelWizard.Engine.ModelBuilderEngine+GenerateSSDLException' occurred while attempting to update from the database. The exception message is: 'An error occurred while executing the command definition. See the inner exception for details.' Fatal error encountered during command execution. Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. There's nothing special about the affected tables, and it's never the same table(s), it's just that after a certain (unspecific) number of tables have been added, the context can no longer be updated without the "Timeout expired" error. Sometimes it's only one table left over, and sometimes it's three; results are pretty unpredictable. Furthermore, the variance in the number of tables which can be added before the error indicates to me that perhaps the problem lies in the size of the query being generated to update the context which includes both the existing table definitions, and also the new tables that are being added to it. Essentially, the SQL query is getting too large and it's failing to execute for some reason. If I generate the model with EdmGen2 it works without any errors, but the generated EDMX file cannot be updated within Visual Studio without producing the aforementioned exception. In all likelihood the source of this problem lies in the tool within Visual Studio given that EdmGen2 works fine, but I'm hoping that perhaps others could offer some advice on how to approach this very unique issue, because it seems like I'm not the only person experiencing it. One suggestion a colleague offered was maintaining two separate EBMX files with some table crossover, but that seems like a pretty ugly fix in my opinion. I suppose this is what I get for trying to use "new technology". :(

  • How to clone a Model using Entity Framework and ASP.Net Mvc 2

    - by Picflight
    I have the following class: [MetadataType(typeof(PortalMetaData))] [System.Web.Mvc.Bind(Exclude = "PortalId")] public partial class Portal { public Portal() { this.Created = DateTime.Now; } } public class PortalMetaData { [Required(ErrorMessage = "Portal name is required")] [StringLength(50, ErrorMessage = "Portal name must be under 50 characters")] public object PortalName { get; set; } [Required(ErrorMessage = "Description is required")] public object Description { get; set; } } I have a corresponding Table in the database Portal I use the Portal table with a PortalController for the Site Admin to update the records in the Portal Table. I want another user with a different Role (AsstAdmin) to be able to update this table as well. To facilitate that I am thinking of creating a separate partial class that somehow links back to the Portal Model. This would allow me to display limited Fields for update by the AsstAdmin and I can display a different name for the Field as well. How can I accomplish this task? If I add the following class which inherits from Portal than I get an exception: Unable to cast object of type 'Project1.Mvc.Models.Portal' to type 'Prpject1.Mvc.Models.Site'. [MetadataType(typeof(SiteMetaData))] public class Site : Portal { public Site() { } } public class SiteMetaData { [Required(DisplayName = "Site Description")] public object Description { get; set; } }

  • Error handling in Rails Controller for adding embedded Mongoid documents to Model

    - by Dragonfly
    I have a Item model that has embedded documents. Currently, the following comments_controller code will add a comment to the item successfully. However, if pushing the comment document onto the comments array on item fails, I will not know this. #this does work, but i do not know if the push fails def create comment = Comment.new(:text => params[:text]) @item.comments << comment render :text => comment end I would like to have something like this, but @item.comments << comment does not return true or false: #this does not work def create comment = Comment.new(:text => params[:text]) if @item.comments << comment render :text => comment else render :text => 'oh no' end end Nor does it throw an exception when the document push fails: #this does not work def create begin comment = Comment.new(:text => params[:text]) @item.comments << comment render :text => comment rescue Exception => e render :text => 'oh no' end end Thanks!

  • Objective-C memory model

    - by TofuBeer
    I am attempting to wrap my head around one part of the Objective-C memory model (specifically on the iPhone, so no GC). My background is C/C++/Java, and I am having an issue with the following bit of code (also wondering if I am doing this in an "Objective-C way" or not): - (NSSet *) retrieve { NSMutableSet *set; set = [NSMutableSet new]; // would normally fill the set in here with some data return ([set autorelease]); } - (void) test { NSSet *setA; NSSet *setB; setA = [self retrieve]; setB = [[self retrieve] retain]; [setA release]; [setB release]; } start EDIT Based on comments below, the updated retrieve method: - (NSSet *) retrieve { NSMutableSet *set; set = [[[NSMutableSet alloc] initWithCapacity:100] autorelease]; // would normally fill the set in here with some data return (set); } end EDIT The above code gives a warning for [setA release] "Incorrect decrement of the reference count of an object is not owned at this point by the caller". I though that the "new" set the reference count to 1. Then the "retain" call would add 1, and the "release" call would drop it by 1. Given that wouldn't setA have a reference count of 0 at the end and setB have a reference count of 1 at the end? From what I have figured out by trial and error, setB is correct, and there is no memory leak, but I'd like to understand why that is the case (what is wrong with my understanding of "new", "autorelease", "retain", and "release").

  • How to prepopulate an Outlook MailItem and avoiding a com Exception from the object model guard

    - by torrente
    Hi, I work for a company that develops a CRM tool and offers integration with MS Office(2003 & 2007) from windows XP to 7. (I'm working using Win7) My task is to call an Outlook instance (using C#) from this CRM tool when the user wants to send an email and prepopulate with data of the CRM tool (email, recipient, etc..) All of this already works just fine. The problem I'm having is that Outlook's "object model guard" is throwing com Exception (Operation aborted (Exception from HRESULT: 0x80004004 (E_ABORT))) the moment I try to read a protected value from the mailItem (such as mail.bodyHTML). Example Snippet: using MSOutlook = Microsoft.Office.Interop.Outlook; //untrusted Instance _outlook = new MSOutlook.Application(); MSOutlook.MailItem mail = (MSOutlook.MailItem)_outlook.CreateItem(MSOutlook.OlItemType.olMailItem); //this where the Exception occurs string outlookStdHTMLBody = mail.HTMLBody; I've done quite a bit of reading and know that my Outlook Instance (derived by using new Application) is considered untrusted and therefore the "omg" kicks in. I do have a workaround for development: I'm running VS2010 as Administrator and if I run Outlook as Administrator as well - all is good. I suppose this is due to them having the same integrity levels(high) and the UAC(?) is not complaining. But that just ain't the way to go for deployment. Now the question is: Is there a way to obtain a trusted instance of Outlook so that I can avoid this exception? I've already read that when developing an Office Add-In using VSTO one can obtain a trusted Instance from the OnComplete event and/or using "ThisAddin" But I "merely" want to start an outlook instance and preopulate it, and do not want to develop an Add-In since this is not the requirement. And to make it clear - I have no problem with pop ups informing the user that outlook is being accessed - I just want to get rid of the exception! So how can I get around this problem using code? Any help is highly appreciated! Thomas

  • Adapting existing HTML/Javascript model to Titanium's latest release (v 0.9)

    - by Alan Neal
    In pre-0.9 versions of Titanium, one could simply specify an .html file (local or remote) in the tiapp.xml file and interact with it in the same manner as one would on a website. As of version 0.9, that is no the longer case. One creates their entire app dynamically. Unfortunately, this broke my previous implementation and, other than an updated Kitchen Sink, much of the new model and API calls are not covered in the documentation (e.g., createLabel). So, my question is this... What are the simplest steps for re-creating the previous effect (knowingly forgoing some of the advantages of the Titanium's latest approach if necessary)? My previous implementation was exactly as it functions on the website. The website has a single index.html file with no content other than links to JavaScript and style files. The document body's onload event called the first JavaScript function (located in the main script) and, from that point forth, the entire content was dynamically created. How can I set up the latest version of Titanium so that I am poised to do the exact same thing? BTW: Whereas I previously had the choice to keep the files local or remote, I don't believe that remote access (e.g., simply using the webView widget to point to the website) is viable. That's because pages displayed via the webView do not have access to most of the API. Since the iPhone and Safari browsers do not support the file input type, the only means for uploading files (something my app requires) is calling Titanium's function. Thanks in advance.

  • How to implement two way binding between an ActiveX control and a WPF MVVM View Model

    - by Zamboni
    I have a WPF application implemented using the MVVM framework that uses an ActiveX control and I need to keep the WPF and ActiveX UI synchronised. So far I can update the ActiveX UI when I change the WPF UI using the code at the bottom of the question that I got from the article Hosting an ActiveX Control in WPF and this question. But I cannot update the WPF UI when I make a change in the ActiveX UI. I suspect that I need to fire the PropertyChanged event from my ActiveX control but I have no idea how to do this or if it is even possible. The ActiveX controls I have written are in VB6 and MFC as I am just prototying at this time for the eventual integration of VB6 ActiveX controls in a WPF contaner application. Here is a code snipet that indicates the work done so far: System.Windows.Forms.Integration.WindowsFormsHost host = new System.Windows.Forms.Integration.WindowsFormsHost(); // Create the ActiveX control. AxTEXTBOXActiveXLib.AxTEXTBOXActiveX axWmp = new AxTEXTBOXActiveXLib.AxTEXTBOXActiveX(); // Assign the ActiveX control as the host control's child. host.Child = axWmp; axWmp.DataBindings.Add(new System.Windows.Forms.Binding("ActiveXStatus", (MainWindowViewModel)this.DataContext, "ModelStatus", true, DataSourceUpdateMode.OnPropertyChanged )); // Add the interop host control to the Grid // control's collection of child controls. this.activexRow.Children.Add(host); How to implement two way binding between an ActiveX control and a WPF MVVM View Model?

  • Cannot return view model after POST

    HI, I am trying to return a model after a POST but I receive the following error: Exception Details: System.InvalidOperationException: Operation is not valid due to the current state of the object. Line 29: public UsersModel getUser(Int32 id) { Line 30: return ( Line 31: from users in db.NUsers Line 32: join userSettings in db.NUsersSettings The code in the controller looks like this: [AcceptVerbs( HttpVerbs.Post )] public ActionResult Edit( NUsers user ) { //Other code that doesn't affect the error :) UsersModel userDetails = this.usersObj.getUser( user.UserID ); return View( userDetails ); } The getUser method looks like this: public UsersModel getUser(Int32 id) { return ( from users in db.NUsers join userSettings in db.NUsersSettings on users.UserID equals userSettings.UserID where users.UserID == id select new UsersModel { UserId = Convert.ToInt32( users.UserID ), Email = Convert.ToString( users.Email ), FirstName = Convert.ToString( users.FirstName ), LastName = Convert.ToString( users.LastName ), Language = Convert.ToString( userSettings.Language ), Phone = Convert.ToString( users.Phone ) } ).First(); } and finally the UsersModel if you think it is relevant: public class UsersModel { public int UserId; public string Email; public string FirstName; public string LastName; public string Language; public string Phone; public List<NLanguages> Languages; public UsersModel() { Models.Languages languagesObj = new Models.Languages(); Languages = languagesObj.getLanguages(); } } Any thoughts on what might be causing the error and what can I do to fix it?
