  • Opening a View with a Table without a NavigationController

    - by Ken
    Hiya, I'm pretty new to developing with Cocoa Touch/XCode and I came across a problem. I'm making a sort of RSS reader for a newssite and I have 5 views of tables navigated with 5 tabs in a TabBarController. If someone selects a newsitem I want another view to open showing the complete newsitem. My problem is that it won't work. This is my code: - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection(NSInteger)section{ return [[[self rssParser]rssItems]count]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{ UITableViewCell * cell = [tableView dequeueReusableCellWithIdentifier:@"rssItemCell"]; if(nil == cell){ cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"rssItemCell"]autorelease]; } cell.textLabel.text = [[[[self rssParser]rssItems]objectAtIndex:indexPath.row]title]; cell.detailTextLabel.text = [[[[self rssParser]rssItems]objectAtIndex:indexPath.row]description]; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; return cell; } - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { [[self appDelegate] setCurrentlySelectedBlogItem:[[[self rssParser]rssItems]objectAtIndex:indexPath.row]]; [self.appDelegate loadNewsDetails]; } And it calls this method in my delegate: -(void)loadNewsDetails{ [[self rootController]pushViewController:detailController animated:YES]; } Please tell me what I'm doing wrong. BTW I do not want to use a NavigationController, just the tabbar I'm using. Thanks in advance, Ken

  • UITouch Event Propagation To Background UIViews

    - by drewww
    I'm having troubles getting any UIView that's not the foreground UIView to receive UITouch events. I'm building an all-Core Graphics-app, so I'm not using any built in UIViews or IB or anything - everything is programmatically constructed and drawn into. Here's my view hierarchy: Root View Type A Container Type A View Type A View Type A View Type B Container Type B View Type B View Type B View The containers are just vanilla UIView objects that I create programmatically and add instances of Type A and B to when they're created. I did this originally to make hitTesting easier—Type A objects can be drag-and-dropped onto Type B objects. Type A objects receive touch events fine, but Type B objects (which are contained by Type B Container which is behind Type A Container) don't receive touch events. Both containers occupy the entire screen; they're basically just convenience containers. If I pull Type B Container to the front (eg [self.view bringSubviewToFront:Type B Container]) it receives events properly, but then the Type A Container doesn't get events. How do I propagate events from the view that's on top? Both views occupy the entire screen, so it makes sense that the top-most view is catching the events, but how should I get it to pass those events on to Type B Container? I could inject some code in the container that passes the touch events back to the main ViewController which can pass them on to Type B Container but that feels really messy to me. Is there a nicer way to not have the Type A Container stop propagation? What's the best practice here?

  • Wpf Mvvm ComboBox

    - by 2Fast4YouBR
    Hi All, I am new in the Wpf world, so I created a couple of views and all of them have at least one ComboBox, as I am using the MvvM pattern, I get my self re-typing all the time the same line of codes to fill the Combo and to get the SelectedItem (creating properties, privates for fill and other to get). Is there some kind of framework that can improve this part ? or hack/trick ??? as I see too much repetitive code... maybe I am doing something wrong, take a look: XAML: <ComboBox name= "cbDepartments" DisplayMemberPath="DepartmentName" SelectedValuePath ="PrimaryKey" ItemsSource="{Binding Path=Departments}" SelectedItem="{Binding Path=DefaultBranch,Mode=TwoWay}" > ViewModel: private Department defaultBranch; public Department DefaultBranch { get { return this.defaultBranch; } set { if (this.defaultBranch != value) { this.defaultBranch = value; this.OnPropertyChanged("DefaultBranch"); this.saveChangeCommand.RaiseCanExecuteChanged(); this.UserMessage = string.Empty; } } } private ObservableCollection<Department> departments; public ObservableCollection<Department> Departments { get { return this.departments; } set { if (this. departments!= value) { this. departments = value; this.OnPropertyChanged("Departments"); } } }

  • AlertDialog in if-stetement doesn't show()

    - by Steffen Kern
    I have the following code: public void button_login(View view) { // Instantiate an AlertDialog.Builder with its constructor AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setPositiveButton(R.string.ok, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int id) { /* User clicked OK button */ } }); // Preserve EditText values. EditText ET_username = (EditText) findViewById(R.id.username); EditText ET_password = (EditText) findViewById(R.id.password); String str_username = ET_username.toString(); String str_password = ET_password.toString(); // Intercept missing username and password. if(str_username.length() == 0) { builder.setMessage(R.string.hint_username_empty); AlertDialog dialog = builder.create(); dialog.show(); } } I have an activity that includes the two EditText-Views and a button. When I click the button the shown method will be called. My problem: The AlertDialog doesnt show up! When I put the create and show at beginning like this: // Instantiate an AlertDialog.Builder with its constructor AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setPositiveButton(R.string.ok, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int id) { /* User clicked OK button */ } }); builder.setMessage(R.string.hint_username_empty); AlertDialog dialog = builder.create(); dialog.show(); // Preserve EditText values. EditText ET_username = (EditText) findViewById(R.id.username); EditText ET_password = (EditText) findViewById(R.id.password); String str_username = ET_username.toString(); String str_password = ET_password.toString(); // Intercept missing username and password. if(str_username.length() == 0) { } } Then the Dialog shows up. Any ideas why the dialog doesnt show up in the first place? Greetz, Steffen

  • XAML itemscontrol visibility

    - by Sam
    Hello, I have a ItemsControl in my XAML code. When some trigger occur i want to collapse the full itemsControl, so all the elements. <ItemsControl Name="VideoViewControl" ItemsSource="{Binding Videos}"> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <WrapPanel ItemHeight="120" ItemWidth="160" Name="wrapPanel1"/> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> <ItemsControl.ItemTemplate> <DataTemplate> <views:VideoInMenuView /> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> The trigger: <DataTrigger Value="videos" Binding="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type UserControl}, AncestorLevel=1}, Path=DataContext.VideosEnable}"> <Setter Property="ScrollViewer.Visibility" Value="Visible" TargetName="test1" /> <Setter Property="ScrollViewer.Visibility" Value="Collapsed" TargetName="test2" /> <Setter Property="WrapPanel.Visibility" Value="Collapsed" TargetName="wrapPanel1" /> </DataTrigger> When I add the last setter the program crashes. Without this last setter it works fine but no visibility change.... What is wrong with this code? What is the write method to collapse all the elements of a ItemsControl with a trigger?

  • How to use javascript-xpath

    - by Nirmal Patel
    I am using Selenium RC with IE 6 and XPath locators are terribly slow. So I am trying to see if javascript-xpath actually speeds up things. But could not find enough/clear documentation on how to use native x- path libraries. I am doing the following: protected void startSelenium (String testServer, String appName, String testInBrowser){ selenium = new DefaultSelenium("localhost", 4444, "*" +testInBrowser, testServer+ "/"+ appName + "/"); echo("selenium instance created:"+selenium.getClass()); selenium.start(); echo("selenium instance started..." + testServer + "/" + appName +"/"); selenium.runScript("lib/javascript-xpath-latest-cmp.js"); selenium.useXpathLibrary("javascript-xpath"); selenium.allowNativeXpath("true"); } This results in speed improvement of XPath locator but the improvements are not consistent. On some runs the time taken for a locator is halved; while sometimes its randomly high. Am I missing any configuration step here? Would be great if someone who has had success with this could share their views and approach. Thanks, Nirmal

  • Winforms MVP with Castle Windsor - DI for subforms?

    - by Paul Kirby
    I'm building a winforms app utilizing passive-view MVP and Castle Windsor as an IoC container. I'm still a little new to dependency injection and MVP, so I'm looking for some clarity... I have a main form which contains a number of user controls, and also will bring up other dialogs (ex. Login, options, etc) as needed. My first question is...should I use constructor injection to get the presenters for these other views into the main view, or should I go back to a Service Locator-type pattern? (which I've been told is a big nono!) Or something else? Second question...the user controls need to communicate back to the main form when they are "completed" (definition of that state varies based on the control). Is there a standard way of hooking these up? I was thinking perhaps just wiring up events between the main presenter and the child presenters, but I'm not sure if this is proper thinking. I'd appreciate any help, it seems that the combination of MVP and IoC in winforms isn't exactly well-documented.

  • Authlogic with nested attributes and polymorphic associations

    - by ferparra
    Hi all! I'm having trouble with the following code: User < AR acts_as_authentic belongs_to :owner, :polymorphic => true end Worker < AR has_one :user, :as => :owner accepts_nested_attributes_for :user end Employer < AR has_one :user, :as => :owner accepts_nested_attributes_for :user end I'd like to create registration forms based on user types, and to include authentication fields such as username and password. I currently do this: UserRegistrationController < AC #i.e. a new Employer def new @employer = Employer.new @employer.build_user end ... end I then include User fields with fields_for. All views render fine, but here's the catch: I cannot build a User, it tells me :password is a wrong method, so I guess the authentication logic was bypassed. What should I do? Am I doing it wrong altogether? Should I drop polymorphic associations in favor of Single Table Inheritance? Whatever I do, I have to make sure it plays nicely with Authlogic.

  • How to explain to users the advantages of dumb primary key?

    - by Hao
    Primary key attractiveness I have a boss(and also users) that wants primary key to be sophisticated/smart/attractive control number(sort of like Social Security number, or credit card number format) I just padded the primary key(in Views) with zeroes to appease their desire to make the control number sophisticated,smart and attractive. But they wanted it as: first 2 digits as client code, then 4 digits as year year, then last 4 digits as transaction number on that client on a given year, then reset the transaction number of client to 1 when next year flows. Each client's transaction starts with 1. e.g. WM20090001, WM20090002, BB2009001, WM20100001, BB20100001 But as I wanted to make things as simple as possible, I forgo embedding their suggested smartness in primary key, I just keep the primary key auto increments regardless of client and year. But to make it not dull-looking(they really are adamant to make the primary key as smart control number), I made the primary key appears to them smart, on view query, I put the client code and four digit year code on front of the eight-zero padded autoincrement key, i.e. WM200900000001. Sort of slug-like information on autoincremented primary key. Keeping primary key autoincrement regardless of any other information, we are able keep other potential side effects problem when they edit a record, for example, if they made a mistake of entering the transaction on WM, then they edit the client code to BB, if we use smart primary key, the primary keys of WM customer will have gaps in their control number. Or worse yet, instead of letting the control numbers have gaps/holes, the user will request that subsequent records of that gap should shift up to that gap and have their subsequent primary keys re-adjust(decremented). How do you deal with these user requests(reasonable or otherwise)? Do you yield to their request? Or just continue using dumb primary key and explain them the repercussions of having a very smart/sophisticated primary key and educate them the significant advantages of having a dumb primary key? P.S. quotable quote(http://articles.techrepublic.com.com/5100-10878_11-1044961.html): "If you hold your tongue the first time users ask what is for them a reasonable request, things will work a lot better in the end."

  • Mimic CALayer shadow properties found in iPhone OS 3.2 for OS 3.1

    - by niblha
    The CALayer shadow properties like shadowOffset, shadowRadius, shadowColor are not available in iPhone OS versions below 3.2 and I'm wondering how I could mimic that functionality for use with 3.1 and below. I want to use this to be able to add drop shadows to UIViews in a clean way so that the shadows are drawn at layer level somehow, and not by drawing it in a view's -(void)drawRect:(CGRect)rect method which requires to shrink the actual views frame to accomodate for the shadow. (This shrinking approach have been proposed in the other UIView drop shadow related questions I found here on SO). I was thinking a layered approach would be cleaner. For example I tried creating subclassing CALayer to which I added a separate shadow layer as a sublayer, but then that would be drawn on top of whatever was draw in the drawRect: method of the UIView that had the main layer as backing layer. I've also tried implementing the subclass CALayer's drawInContext: something like this, - (void)drawInContext:(CGContextRef)ctx { // code to draw shadow for a frame the size of the layer's frame [super drawInContext:ctx]; } But then the shadow is still clipped to the current clipping bounding box of the context, which seems to be the layers own frame. I also had some idea of redirecting the drawing of the main layer to a sublayer, which would be placed above another sublayer which had the shadow drawn onto it. Then I would probably get rid of the clipping and the shadow would be farthest away. But I couldn't really wrap my head around how I would do that, and it doesn't really feel like a clean approach. Any ideas on how to go about this? Just to make clear how my UIView drop shadow related question is different from the other ones I found here on SO; I do not want to shrink the actual drawing frame of a UIView to accomodate for a shadow. I want it to somehow be on a separate layer in the background, whithout beeing clipped.

  • Best practice for structuring a new large ASP.NET MVC2 plus EF4 VS2010 solution?

    - by Nick
    Hi, we are building a new web application using Microsoft ASP.NET MVC2 and Entity Framework 4. Although I am sure there is not one right answer to my question, we are struggling to agree a VS2010 solution structure. The application will use SQL Server 2008 with a possible future Azure cloud version. We are using EF4 with T4 POCOs (model-first) and accessing a number of third-party web-services. We will also be connecting to a number of external messaging systems. UI is based on standard ASP.NET (MVC) with jQuery. In future we may deliver a Silverlight/WPF version - as well as mobile. So put simply, we start with a VS2010 blank solution - then what? I have suggested 4 folders Data (the EF edmx file etc), Domain (entities, repositories), Services (web-services access), Presentation (web ui etc). However under Presentation, creating the ASP.NET MVC2 project obviously creates it's own Models folder etc and it just doesn't seem to fit too well in this proposed structure. I'm also missing a business layer (or does this sit in the domain?). Again I am sure there is no one right way to do it, but I'd really appreciate your views on this. Thanks

  • How Can i reload data in tableview in view controller in iphone

    - by Pugal Devan
    Hi, I am new to iphone development. I have created 5 buttons in the view. On clicking the buttons it navigates to the corresponding views. On clicking the "News" button it navigates and displayed the parsing details in the table view.(This table view, I have created View controller and added table view using Interface Builder and i have set all the properties.) and i go to another button and comes back to the "News" button, every time parsing will happened.How to avoid the multiple parsing when i come back to the button. i have tried this one and my code is, - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; static int i; if(i == 0) { NSString * path = @"http://www.AAAAAAAAAAAAAAAA.com"; [self parseXMLFileAtURL:path]; i++; } [self.newsTable reloadData]; } } Now the parsing is happened only time but the datas are doesnt displayed. My problem is the tableview doesnot reload. newsTable is the instance of the Tableview. How can i achieve this. Please help me out. Thanks.

  • UITableViewController not redrawing new cell text label after popViewControllerAnimated

    - by crunchyt
    I have a problemetic UITableViewController fails to redraw an updated cell after a child view is removed. Here's what's happening. After changing data in a child view, the parent view controller reloads the source data array and runs [tableView reloadData] via a PostNotification. After this triggers, I use popViewControllerAnimated to return to the parent UITableViewController (this pops the child view off the stack, and reveals the controller one level up). However, my updated data does not appear in the parent view controller! According to the debugger, the cell's label has been updated, but the visible label does not change. However, if I scroll-flick the table, momentarily moving the updated cell out of view, when it reappears the label is updated! I also try calling [tableView reloadData] via viewWillAppear but the issue still persists. Here is some additional info that may be helpful. I have a 3 views structured like this: 1/ SettingsViewController : UITableViewController 2/ -- UserView : UITableViewController 3/ ---- UserDetailsView : UIViewController <UIActionSheetDelegate> I am calling UserDetailsView from inside UserView as follows: UserDetailsView *userDetailsView = [[UserDetailsView alloc] init]; [self.navigationController pushViewController:userDetailsView animated:YES]; If I return to the top-most controller (SettingsViewController) and then load the problematic controller (UserView), everything is drawn correctly. It is only when returning from a child view that this issue occurs. Thank you in advance for your suggestions.

  • shouldAutorotateToInterfaceOrientation won't work!

    - by Dror Sabbag
    Hey. I've been writing my Universal application in portrait mode, and now after about 15 nib files, many many viewCotnrollers, i'd like to implement the shouldAutorotateToInterfaceOrientation and desing some screens in Landscape mode. adding : - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } to ALL of my viewControllers, does not do the work. During Debug, i see that this method is called, but it just won't work! not in the simulator, not in the device, not in Iphone, not in Ipad! i've searched some answers in the forum, and saw some advises to use: - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return (interfaceOrientation == UIInterfaceOrientationPortrait || interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation == UIInterfaceOrientationLandscapeRight || interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown ); } Didn't worked either, adding: [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications]; and [[UIDevice currentDevice] endGeneratingDeviceOrientationNotifications]; to my viewDidLoad and viewDidUnload respectively didn't worked either. I'm lost.. Any help will do! just one more info... all my Views are of type UIControl, as i needed the TuchUpInside to work. Appriciate your help.

  • Getting Android SDK WebView and TabWidget to play nice

    - by jdandrea
    I’m taking the HelloTabWidget Android example and trying two things: Moving the tabs to the bottom vs. the top (if that’s even desirable from an Android UI POV) Making each tab show a particular WebView in the space above I’ve got this for a layout (high level): <TabHost> <LinearLayout> <FrameLayout> <WebView/> <WebView/> <WebView/> <WebView/> <WebView/> </FrameLayout> <TabWidget/> </LinearLayout> </TabHost> Everything has a width/height set to fill_parent except for the TabWidget which has its layout_height set to wrap_content (and the layout_gravity set to bottom). First thing I noticed is that WebViews don’t show anything until all the parents have width/height set to fill_parent. However, once I do that, they fill the entire display, obscuring the TabWidget. Is there some other trick to making these two views play nicely together?

  • undefined method `build_users' with nested models

  • Could CouchDB benefit significantly from the use of BERT instead of JSON?

    - by Victor Rodrigues
    I appreciate a lot CouchDB attempt to use universal web formats in everything it does: RESTFUL HTTP methods in every interaction, JSON objects, javascript code to customize database and documents. CouchDB seems to scale pretty well, but the individual cost to make a request usually makes 'relational' people afraid of. Many small business applications should deal with only one machine and that's all. In this case the scalability talk doesn't say too much, we need more performance per request, or people will not use it. BERT (Binary ERlang Term http://bert-rpc.org/ ) has proven to be a faster and lighter format than JSON and it is native for Erlang, the language in which CouchDB is written. Could we benefit from that, using BERT documents instead of JSON ones? I'm not saying just for retrieving in views, but for everything CouchDB does, including syncing. And, as a consequence of it, use Erlang functions instead of javascript ones. This would modify some original CouchDB principles, because today it is very web oriented. Considering I imagine few people would make their database API public and usually its data is accessed by the users through an application, it would be a good deal to have the ability to configure CouchDB for working faster. HTTP+JSON calls could still be handled by CouchDB, considering an extra cost in these cases because of parsing.

  • TabHost NullPointerException in layout

    - by Chubbs
    I been following the Tab example provided by Google. I am trying to use the XML layout provided to setup a tab layout. I use this XML layout @ http://developer.android.com/guide/tutorials/views/hello-tabwidget.html <?xml version="1.0" encoding="utf-8"?> <TabHost xmlns:android="http://schemas.android.com/apk/res/android" android:id="@android:id/tabhost" android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TabWidget android:id="@android:id/tabs" android:layout_width="fill_parent" android:layout_height="wrap_content" /> <FrameLayout android:id="@android:id/tabcontent" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TextView android:id="@+id/textview1" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="this is a tab" /> <TextView android:id="@+id/textview2" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="this is another tab" /> <TextView android:id="@+id/textview3" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="this is a third tab" /> </FrameLayout> </LinearLayout> </TabHost> When ever I switch the Layout tab in the Eclipse layout designer I get a NullPointerException: null error inside my Eclipse. This happens also when I try to drag and drop a TabHost, and then a TabWidget into an empty layout file. What am I doing wrong ? this seems pretty simple.

  • Unexpected Html.EditorFor behavior in ASP.NET MVC 2

    - by NickLarsen
    I am getting some unexpected behavior from Html.EditorFor(). I have this controller: [HandleError] public class HomeController : Controller { [AcceptVerbs(HttpVerbs.Get)] public ActionResult Lister() { string[] values = { "Hello", "world", "!!!" }; return View(values); } [AcceptVerbs(HttpVerbs.Post)] public ActionResult Lister(string[] values) { string[] newValues = { "Some", "other", "values" }; return View(newValues); } } And this is my view which is intended to work for both of these: <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<string[]>" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> Lister </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2>Lister</h2> <% using (Html.BeginForm()) { %> <% foreach (string value in Model) { %> <%= value %><br /> <% } %> <%= Html.EditorForModel() %> <input type="submit" value="Append Dashes" /> <% } %> </asp:Content> And the problem is that when the post back is made from the view, it hits the correct action, but the text boxes still show the original hello world data while the foreach loop outputs the new values. It feels like something in ASP.NET is overriding my model values from updating the text boxes and they are just displaying the same old values. I found this issue while trying to learn EditorFor with an IEnumerable.

  • How do I place widgets above and below a listview with Relative Layout

Thus far, it allows for a user to sign up for their own account, create posts, tags, comments, etc. I have just implemented the ability to use www.myapp.com/brandon to set @user to find by username and therefore correctly display the users information at each url. So when you go to www.myapp.com/brandon you see all Brandon's posts, tags, and comments associated with those posts, etc. Works great. I'm implementing this URL mapping through the routes.rb file by adding the following: map.username_link '/:username', :controller => 'posts', :action => 'index' And then just setting the @user variable in the PostController and corresponding views to find_by_username. Now the issue is this. Once at www.myapp.com/brandon when you click on a post title, it sends to myapp.com/posts/id without the username in the URL. How do I tell rails to replace the /posts with /username. Is it even possible to insert the user_username variable into this code? map.resources :posts, :as => [what goes here]

  • Navigating between pages in a Facebook Platform iframe application

    - by Jimmy Cuadra
    I'm working on a Facebook Platform application that runs in iframe mode, and I'm having trouble understanding how to navigate between pages within the app. Let's say the first page that is loaded within the iframe at my canvas URL is one.html. Within that page, there is a link to two.html that just changes the source of the iframe and doesn't reload the Facebook chrome. When I do this, all the Facebook fb_sig_* query string parameters that Facebook passes to the original page aren't included, and so two.html has no awareness of the connection to Facebook and no ability to make API calls to generate the content for the page. One possible solution would be to manually extract all the Facebook parameters from one.html and append it to the link to two.html myself. This seems really ugly and I figured there had to be a cleaner way. For reference, my application is written in Perl and uses the WWW::Facebook::API module as a client library. I didn't see anything in it that I can use to easily reconstruct the Facebook parameters for use with links in iframe apps. Another possible solution would be to store all the Facebook parameters in a session on my server on the first page load, and just use the values in that session on subsequent page views. But what happens if the data I've stored no longer matches what Facebook would have sent if it were a completely new request (i.e. something in the user's Facebook session changed)? Is there something obvious I'm missing? What is the standard approach to navigating between pages within an iframe app? Facebook's documentation is atrocious and I haven't been able to find anything that clearly explains how this works. I also realize this wouldn't be an issue with an app using FBML instead of an iframe, but my understanding is that iframe apps are now encouraged over FBML apps, though again this seems ambiguous since so much of Facebook's documentation is outdated and contradictory.

  • Linq to Entities and POCO foreign key relations mapping (1 to 0..1) problem

    - by brainnovative
    For my ASP.NET MVC 2 application I use Entity Framework 1.0 as my data access layer (repository). But I decided I want to return POCO. For the first time I have encountered a problem when I wanted to get a list of Brands with their optional logos. Here's what I did: public IQueryable<Model.Products.Brand> GetAll() { IQueryable<Model.Products.Brand> brands = from b in EntitiesCtx.Brands.Include("Logo") select new Model.Products.Brand() { BrandId = b.BrandId, Name = b.Name, Description = b.Description, IsActive = b.IsActive, Logo = /*b.Logo != null ? */new Model.Cms.Image() { ImageId = b.Logo.ImageId, Alt = b.Logo.Alt, Url = b.Logo.Url }/* : null*/ }; return brands; } You can see in the comments what I would like to achieve. It worked fine whenever a Brand had a Logo otherwise it through an exception that you can assign null to the non-nullable type int (for Id). My workaround was to use nullable in the POCO class but that's not natural - then I have to check not only if Logo is null in my Service layer or Controllers and Views but mostly for Logo.ImageId.HasValue. It's not justified to have a non null Logo property if the id is null. Can anyone think of a better solution?

  • Universal Authentication to Google Data API?

    - by viatropos
    Hey, I want to be able to have say 10 admin users store all their documents on google docs for a domain ('http://docs.google.com/a/domain.com'), and have everyone else be able to view them through 'domain.com/documents'. I'm just not certain how the whole authentication thing works in that case. Should I use OAuth? Or could I just use ClientLogin for say the root/global admin, and anytime someone goes to the site, they login as that? That works for personal docs, but it doesn't seem to be working for Google Apps. I would like it so the user has no idea they're accessing google docs, so I don't want them to have to say "Yes, Authenticate this App with Google", as seen in this Doclist Manager App. The app is basically: Admin stores a bunch of forms and documents User uses form and views documents the admin has posted ... so there's no need to access the user's Google Docs. But it seems like AuthSub and OAuth are addressing that instead... Thanks for the tips.
