  • PHP APC and Pecl upload progress returning false/null.

    - by Keyo
    This is a long shot. I believe this might be suhosin patch issue. Here is my php from codeigniter: public function uploadprogress($id) { if ($id) { header("Cache-Control: no-cache, must-revalidate"); header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); echo json_encode(apc_fetch('upload_'.$id)); exit(); } } public function uploader() { $this->load->view('myid/' . $this->router->class . '_uploader'); //phpinfo(); } script: <script type="text/javascript"> $(document).ready(function(){ var progress_key = $('#progress_key').val(); // this sets up the progress bar $('#uploadform').submit(function() { setTimeout(beginUpload,1500); return; }); function beginUpload() { $("#progressbar").progressbar({ value:0}).fadeIn(); var i = setInterval(function() { $.getJSON("/myid/videos/uploadprogress/" + progress_key, function(data) { alert('data'); if (data == null) { clearInterval(i); location.reload(true); return; } var response; eval ("response = " + data); if (!response) return; var percentage = Math.floor(100 * parseInt(response['bytes_uploaded']) / parseInt(response['bytes_total'])); $("#progressbar").progressbar({value:percentage}); }, 1500); }); } }); </script> Has anyone had strange troubles with this before? The upload key is the same on the view and the uploadprogress method. I've Tried apc and pecl upload-progress both return false or null. I wondering if it's just suhosin patch messing up everything?

  • NetBeans Tips and Tricks

    - by cdmckay
    I just saw an Eclipse tips & tricks post and was wondering if anyone had any tips & tricks for my IDE of choice: NetBeans. Here's a few I know and find to be useful: Removing a package: After you remove a package in NetBeans, it sticks around as a grayed-out package in your Project view. To get rid of that, switch to Files view and delete the directory. Alt-Insert (in Windows) opens up a Generate submenu at your cursor. A nice shortcut for quickly generating getters/setters (among other things). Selecting a chunk of code, right-clicking and then clicking "Refactor Introduce Method" will have NetBeans introduce a method, complete with arguments and return value. Of course you have to make sure the chunk of code only has one return value. Sometimes when you run a build and it crashes, the Java window sticks around at the bottom. I used to just click X until Windows let me End Task, but there's a nicer way to get rid of them. Click "Run Stop Build/Run" and NetBeans will close the window for you. It'll even let you close multiple applications at once. These may seem obvious to grizzled NetBeans developers, but I thought they might be useful for NetBeans newbs like me. Anyone else have any tips/tricks to share? Here are some from the comments: NetBeans allows for code templates. You can even add yours on the Code Templates tab under the Editor settings on the Options window. Some examples: Type sout and hit the tab key as a shorcut for System.out.println("") Type psvm and hit the tab key as a shorcut for public static void main(String args[]) {} Ctrl Shift C: Comments out the selected block of code. Alt Shift F: Formats the selected block of code. Ctrl E: Deletes current line. Ctrl Shift I: Fixes your imports, handy if you've just written a piece of code that needs a lot of packages imported.

  • How to change type of information for a Title column in SharePoint MOSS 2007 List?

    - by Ruba
    I created a calendar in SharePoint MOSS 2007 that is connected to my Outlook. I added a custom column “Person” to this list and the type of information in this column is: Person or Group. In SharePoint I can hide Title column and in Calendar View show this Person field as Month View Title. So I can see on the calendar who is working that day. Problem is in Outlook. It seems like Outlook doesn’t know a thing about custom fields. In Outlook I can see only Title and few other fields. I could rename Title field to Person, but I can’t change type of information that it contains. By default it is text field and no way to change it to Person or Group. If I could change those “default” column types, then I think my problem would be solved. I know it is possible. I created a custom list, but this list has also those “sticky” Title, Created By and Modified By columns that can’t be changed or removed. Maybe I have to create a custom list with some other program or code? Please help! Thanks in advance!

  • Interception with Unity in Prism v2 for WPF (not working for me)

    - by Bobby Chopra
    I cannot get interception to work with Prism v2 (Oct 2009). I am trying to intercept the Setter for any Public Properties and then fire the PropertyChanged event if the property has changed. I can see that the code gets executed (by stepping through with the debugger or adding a debug point). However, the WPF Window controls that are bound to these properties do not get updated. If I subscribe to these events and print to the console, I can print out the property change notifications. So, if the View has a textbox, which updates the property on the ViewModel, then the property in the ViewModel gets updated. However, if a button on the view (implemented as a DelegateCommand) causes the property to get updated, then the textbox (TwoWay Binding Mode) that is bound to that Property is not updated even though the event is triggered and the console has printed out the information about which property was updated. Has anyone encountered this issue? Here is the sample WPF Application that I have written. Wordpress doesn't allow uploads of zip files, so I renamed it to have a pdf extension (rename the file to have a zip extension). Please let me know what I am doing wrong. Thanks in advance.

  • Is this a tableView issue or a CoreData Issue

    - by monotreme
    I have a CoreData-driven navigation app and I'm trying to figure out why It's crashing. I've got a hierarchy which is 3 view Controllers deep, all related by coredata relatioships, like this. TableViewA =relationship= TableViewB =relationship= TableViewC I'm honestly a novice at core data and I think my problem lies in the fetched results controller. I have one in TableViewA and another in TableViewB, and no matter how deep I go, the console always cites TableViewB's fetched results controller methods after a crash. Is this the problem? What's happening specifically is if I launch my app and drill down into the hierarchy of one record, let's call it Record1, I can delete sub records to my hearts content. Gone! no problem! But the second I go back to TableViewA and drill down into a different record, let's call that one Record2, and try to delete it's subrecords my app crashes, with the console citing this code from TableViewB as the problem. - (void)controllerWillChangeContent:(NSFetchedResultsController *)controller { // The fetch controller is about to start sending change notifications, so prepare the table view for updates. [self.tableView beginUpdates]; } When I go into the debugger, the specific method it always has a problem with is: if (![x.managedObjectContext save:&error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); } Just a confirmation of my idiocy with CoreData is all I'm looking for I think. Oh and how many ManagedObjectContexts should I have in an app of this type. I've been told I should have separate ones for adding content, which then should re-integrate into the main one. Is this true? Thanks!

  • asp.net Membership : Extending Role membership?

    - by mark smith
    Hi there, I am been taking a look at asp.net membership and it seems to provide everything that i need but i need some kind of custom Role functionality. Currently i can add user to a role, great. But i also need to be able to add Permissions to Roles.. i.e. Role: Editor Permissions: Can View Editor Menu, Can Write to Editors Table, Can Delete Entries in Editors Table. Currently it doesn't support this, The idea behind this is to create a admin option in my program to create a role and then assign permissions to a role to say "allow the user to view a certain part of the application", "allow the user to open a menu item" Any ideas how i would implement soemthing like this? I presume a custom ROLE provider but i was wondering if some kind of framework extension existed already without rolling my own? Or anybody knows a good tutorial of how to tackle this issue? I am quite happy with what asp.net SQL provider has created in terms of tables etc... but i think i need to extend this by adding another table called RolesPermissions and then I presume :-) adding some kind of enumeration into the table for each valid permission?? THanks in advance

  • 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!

  • How to split the story in indesing markup language

    - by BBDeveloper
    Hi All, I am learning indesign, I have a doubt in story splitting... I want to split the story if the same story is used in two different text frames, I am extracting idml file and getting the needed data. My question is, I have a single story which is used by two text frames (Threaded text), and these two textframes are available in two different spreads. Story.xml contains full story, half of the story is displayed in 1st textframe, next half is displayed in 2nd textframe and the same story ID is referred in both the textframes. Now I want to split this story into two, so I want to know that how much content of the story is added in 1st and 2nd textframe, I think if I find that how many characters or words or lines present in each textframe then it will easy to split the story. We can determine the word and character count using the following steps in indesign CS4 Place the insertion point in a text frame to view counts for the entire thread of frames (the story), or select text to view counts only for the selected text. Choose Window Info to display the Info panel. Is there any property or attribute in idml (xml files like prefrence.xml or story.xml or spread.xml) to find out the number of characters/words/lines of single textframe. Can anyone help me to solve this issue. Thanks in advance.

  • Modifying UINavigation Bar Buttons in SubViews

    - by james
    I'm having trouble trying to modify the navigation bar in the subview portion of my application. self.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(add_Clicked:)] autorelease]; I have no issues modifying the navigation bar in any of my UIViewControllers classes. The simplified application class outline is as such: AppDelegate - UIViewControllerA (has a left and a right navigationBarButton) - Subview is displayed when a SegmentControl is selected. (Within the subview, I'm trying to modify the right NavigationBarButton that is displayed) [self.view addSubview:newControllerName.view]; Methods I have attempted: Trying to set self.navigationItem.rightBarButtonItem within my subview to a new UIBarButtonItem. Creating a pointer to UIViewControllerA within my AppDelegate. The UIViewControllerA contains a function setNavButton I wrote to set the rightBarButtonItem to a button. Then I am referencing the AppDelegate's reference to UIViewControllerA and attempting to call setNavButton. I included a NSLog call to see if that function is being called and it is executing but the NavigationBar isn't being modified. I'm trying to avoid having to push a UIViewController after the SegmentControl is clicked in UIViewControllerA so that I can simulate the SegmentControl as tabs. I'm not getting any errors during compile or run time. Anyone have any ideas?

  • Two-way data binding of controls in a user control inside a FormView

    - by Sandor Drieënhuizen
    I'm trying to perform two-way data binding on the controls in my user control, which is hosted inside a FormView template. FormView: <asp:ObjectDataSource runat="server" ID="ObjectDataSource" TypeName="WebApplication1.Data" SelectMethod="GetItem" UpdateMethod="UpdateItem"> </asp:ObjectDataSource> <asp:FormView runat="server" ID="FormView"> <ItemTemplate> <uc:WebUserControl1 runat="server"></uc:WebUserControl1> </ItemTemplate> <EditItemTemplate> <uc:WebUserControl1 runat="server"></uc:WebUserControl1> </EditItemTemplate> </asp:FormView> User control: <%@ Control Language="C#" ... %> <asp:TextBox runat="server" ID="TitleTextBox" Text='<%# Bind("Title") %>'> </asp:TextBox> The binding works fine when the FormView is in View mode but when I switch to Edit mode, upon calling UpdateItem on the FormView, the bindings are lost. I know this because the FormView tries to call an update method on the ObjectDataSource that does not have an argument called 'Title'. I tried to solve this by implementing IBindableTemplate to load the controls that are inside my user control, directly into the templates (just like I had entered them declaratively like in the code above). However, when calling UpdateItem in edit mode, the container that gets passed into the ExtractValues method of the template, does not contain the TextBox anymore. It did in view mode! I have found some questions on SO that relate to this problem but they are rather dated and don't provide straight forward answers. How do you think I could solve this problem? It seems to be such a simple requirement but apparently it's more like opening a can of worms...

  • How can I load a Class contained in a website from a DLL referenced by that website???

    - by Morgeh
    Ok so this is alittle bit obscure and I'm not sure its the best way of doing what I'm trying to do but here goes. Basically I have a Presentation Layer Dll in my web site which handles the Model View Presenter classes. The presentation layer also handles login for my website and then calls off to a web service. Currently whenever the presentation layer calls to a model it verifies the users details and if they are invalid it calls to a loginHandler which redirects the user to the login page. However I cannot dynamically load a new istance of the Login Page in my website from within my Presentation layer. I've tried to use reflection to dynamically load the class but Since the method call is in the presentation assembly it is only looking within that assembly while the page I want to load is in the website. heres the reflection code that loads the View: public ILoginView LoadView() { string viewName = ConfigurationManager.AppSettings["LoginView"].ToString(); Type type = Type.GetType(viewName, true); object newInstance = Activator.CreateInstance(type); return newInstance as ILoginView; } Anyone got any suggestions on how to search within the website assembly? Ideal I don't want to tie this implementation into the website specifically as the presentation layer is also used in a WPF application.

  • Run ajax scripts on page with navigating with ajax?

    - by Oskar Kjellin
    I got a bit of an issue in my ASP.NET MVC project. I have a chat div in the bottom right corner (like facebook), and of course I do not want this to reload when navigating to all my navigation is ajax. The problem I am facing is that I use the following code on the top of the view page: <script type="text/javascript"> $(document).ready(function() { $('#divTS').hide(); $('a#showTS').click(function() { $('#divTS').slideToggle(400); return false; }); }); </script> The problem is that this code is only loaded with ajax and does not seem to fire? I would like to run all scripts in the newly loaded view, just as if I hadn't navigated with ajax. I cannot put this in the site.master as it only loads once and then probably the divs I am trying to hide doesn't exist. Is there a good way to run scripts in the ajax-loaded div?

  • NSTableView Drag and Drop not working

    - by macatomy
    Hi, I'm trying to set up very basic drag and drop for my NSTableView. The table view has a single column (with a custom cell). The column is bound to an NSArrayController, and the array controller's content array is bound to an NSArray on my controller object. The data displays fine in the table. I connected the dataSource and delegate outlets of the table view to my controller object, and then implemented these methods: - (BOOL)tableView:(NSTableView *)aTableView writeRowsWithIndexes:(NSIndexSet *)rowIndexes toPasteboard:(NSPasteboard *)pboard { NSLog(@"dragging"); return YES; } - (NSDragOperation)tableView:(NSTableView*)tv validateDrop:(id <NSDraggingInfo>)info proposedRow:(NSInteger)row proposedDropOperation:(NSTableViewDropOperation)op { return NSDragOperationEvery; } - (BOOL)tableView:(NSTableView *)aTableView acceptDrop:(id <NSDraggingInfo>)info row:(NSInteger)row dropOperation:(NSTableViewDropOperation)operation { return YES; } I also registered the drag types in -awakeFromNib: #define MyDragType @"MyDragType" - (void)awakeFromNib { [super awakeFromNib]; [_myTable registerForDraggedTypes:[NSArray arrayWithObjects:MyDragType, nil]]; } The problem is that the -tableView:writeRowsWithIndexes:toPasteboard: method is never called. I've looked at a bunch of examples and I can't figure out anything I'm doing wrong. Could the problem be that I'm using a custom cell? Is there something I'm supposed to override in the cell subclass to enable this functionality? EDIT: Confirmed. Switching the custom cell for a regular NSTextFieldCell made dragging work. Now, how do I make drag and drop work with my custom cell?

  • Castle Windsor Dynamic Property in XML config

    - by haxelit
    I'm trying to set the DataContext on ApplicationMainWindow which is a WPF window. When I set it up in the XML like so it leaves the DataContext null: <!-- View Models --> <component id="mainwindow.viewmodel" type="ProjectTracking.ApplicationMainViewModel, ProjectTracking" inspectionBehavior="none" lifestyle="transient"> </component> <!-- UI Components --> <component id="mainwindow.view" type="ProjectTracking.ApplicationMainWindow, ProjectTracking" inspectionBehavior="none" lifestyle="transient"> <parameters> <DataContext>${mainwindow.viewmodel}</DataContext> </parameters> </component> But if I do it this way via C# it works. _Kernel.Register( ... Component.For<ApplicationMainWindow>() .DynamicParameters( (k,d) => { d["DataContext"] = k[typeof(ApplicationMainViewModel)]; }) ); I'm instantiating my window like so: Window window = _Kernel[typeof(ApplicationMainWindow)] as Window; When I configure windsor via the xml config it leaves my DataContext NULL, but when I configure it via code it works like a charm. Do I need to use code to pull this off, or should it work via XML config ? Thanks, Raul

  • CGContext problems

    - by Peyman
    Hi I have a CALayer tree hierarchy A B C D where A is the view's root layer (and I create and add B,C and D layers. I am using the same delegate method `- (void) drawLayer:(CALayer *) theLayer inContext:(CGContextRef)context to provide content to each of these layers (implemented through a switch statement in the above method). At initiation A's content is drawn (A.contents) sequentially through these methods `- (void) drawLayer:(CALayer *) theLayer inContext:(CGContextRef)context -(void) drawCircle:(CALayer *) theLayer inContext:(CGContextRef)context where drawCircle does CGContextSaveGState(context); / draws circle and other paths here / CGContextRestoreGState(context); CGImageRef contentImage = CGBitmapContextCreateImage(context); theLayer.contents = (id) contentImage; CGImageRelease(contentImage); (i.e I save the Context, do the drawing, restore the context, make a bitmap of the context, update the layer's contents, in this case A's, then release the contentimage). When the user then clicks somewhere in the circle at touchesEnded:(NSSet*)touches withEvent:(UIEvent*)event delegate method I then try to paint the content of B by (still in touchesEnded:) CGContextRef context = UIGraphicsGetCurrentContext(); [self drawLayer:self.B inContext:context]; [self.B setNeedsDisplay]; the setNeedsDisplay call the delegate - drawLayer:(CALayer *) theLayer inContext:(CGContextRef)context again but this time the switch statement (using a layer flag) calls [self drawCircle:theLayer inContext:context]; with color red. The problem I am facing is that when -drawCircle: inContext: is called I get a long list of CGContext errors, starting with <Error>: CGContextSaveGState: invalid context and ending with CGBitmapContextCreateImage: invalid context I played around with making context the view's ivar and it worked so i am sure the context is the problem but I don't know what. I've tried CGContextFlush but it didn't help. Any help would be appreciated thank you

  • Appending data to NSFetchedResultsController during find or create loop

    - by Justin Williams
    I have a table view that is managed by an NSFetchedResultsController. I am having an issue with a find-or-create operation, however. When the user hits the bottom of my table view, I am querying my server for another batch of content. If it doesn't exist in the local cache, we create it and store it. If it does exist, however, I want to append that data to the fetched results controller and display it. I can't quite figure that part out. Here's what I'm doing thus far: Passing the returned array of values from my server to an NSOperation to process. In the operation, create a new managed object context to work with. In the operation, I iterate through the array and execute a fetch request to see if the object exists (based on its server id). If the object doesn't exist, we create it and insert it into the operations' managed object context. After the iteration completes, we save the managed object context, which triggers a merge notification on my main thread. At this point, any objects that weren't locally cached in my Core Data store before will appear, but the ones that previously existed do not come along for the ride. I feel like it's something simple I'm missing, and could use a nudge in the right direction.

  • Programatic re-evalutation of MVVM command's "can execute" state

    - by dzs
    Hello! I'm writing a WPF application using the MVVM pattern, based on the following article: WPF Apps With The Model-View-ViewModel Design Pattern I have two buttons on my View with the buttons' "Command" property bound (with data binding) to a given instance of the RelayCommand class (see "Figure 3 The RelayCommand Class" from the article above). The RelayCommand class has support for checking whether the given command can be executed. WPF automatically disables buttons whose command cannot be executed. Each of my commands (in the ViewModel class) start a background operation, and the command cannot be executed again until the background operation is finished. The RelayCommand instances have information whether the background operation is still working or it is finished. My problem is the following: after pressing the any of the buttons, the buttons automaticaly go disabled (which is OK) because the background operation started and the command cannot be executed until it is finished, but after the operation had finished, the buttons don't go enabled automatically because their command's "can be executed" predicate is not automatically reevaluated. The reevaluation can be manually triggered by having the application loose and regain focus (by pressing ALT+TAB). After doing this trick, the buttons get enabled once again. How can I programatically reevaluate the buttons' command's "can execute" state?

  • Ruby page loading very very slowly - how should I speed it up?

    - by Elliot
    Hey guys, I'm going to try and describe the code in my view, without actually posting all the garbage: It has a standard shell (header, footer etc. in the layout) this is also where the sub navigation exists which is based on a loop (to find the amount of options) - on this page, we have 6 subnav links. Then in the index view, we have a 3rd level nav - with 3 links that use javascript to link/hide divs on the page. This means each of those original 6 options, all have their own 3'rd level nav, with each of their own 3 div pages. These three pages/divs have the input form for creating a record in rails, and then the other 2 pages show the records in different assortments. ALL of this code lives on one page (aside from the shell). The original sub nav uses a javascript tab solution, to browse through all of it... (this means its about 6 divs, which all contain 4 divs of function - so about 24 heavy divs). Loading it seems to take forever, although after loaded its extremely fast (obviously). My big question, is how should I attack this? I don't know ajax - although I imagine it'd be a good solution for loading the tabs when clicked. Thanks! Elliot

  • Source of UIView Implicit Animation delay?

    - by iPhoneToucher
    I have a block of UIView animation code that looks like this: [UIView beginAnimations:@"pushView" context:nil]; [UIView setAnimationDelay:0]; [UIView setAnimationDuration:.5]; [UIView setAnimationDelegate:self]; [UIView setAnimationWillStartSelector:@selector(animationWillStart)]; view.frame = CGRectMake(0, 0, 320, 416); [UIView commitAnimations]; The code basically mimics the animation of a ModalView presentation and is tied to a button on my interface. When the button is pressed, I get a long (.5 sec) delay (on iPod Touch...twice as fast on iPhone 3GS) before the animationWillStart: actually gets called. My app has lots going on besides this, but I've timed various points of my code and the delay definitely occurs at this block. In other words, a timestamp immediately before this code block and a timestamp when animationWillStart: gets called shows a .5 sec difference. I'm not too experienced with Core Animation and I'm just trying to figure out what the cause of the delay is...Memory use is stable when the animation starts and CoreAnimation FPS seems to be fine in Instruments. The view that gets animated does have upwards of 20 total subviews, but if that were the issue wouldn't it cause choppiness after the animation starts, rather than before? Any ideas?

  • Grouped UITableView Footer Sometimes Hidden On Quick Scroll

    - by jdandrea
    OK, this one is a puzzler. There is one similar post but it's not similar enough to count, so I'm posting this one. :) I've got a grouped UITableView with a header and footer. The footer includes two UIButton views, side-by-side. Nothing major. Now … there is a toggle button in a UIToolbar at the bottom for more/less info in this table view. So I build my index paths to delete/insert with fade row animation, all the usual ingredients, sandwiched between beginUpdates and endUpdates calls on the UITableView … and this works fine! In also happens that my footer can sometimes be pushed off past the bottom of the display. Here's where it gets weird. If I drag my finger up the display, scrolling the view upward, I should see that footer eventually, right? Well … most of the time I do. BUT, if I flick my finger up, for a faster scroll, the footer is missing. Even if you try to tap in that area - no response. However, if I scroll back down again, just to hide that footer (or rather hide the area where the footer would normally be), and then scroll back up, it's there once again! This only happens when inserting rows. If I delete rows, the footer stays put … unless of course it was already hidden and I didn't perform the aforementioned incantation to get it back. :) I am trying to trace through this, but to no avail. I suppose tracing through scroll operations is a bit of a crazy proposition! Perhaps some creative logging … suggestions, anyone? Or is this a known issue in 3.1 where row insert/deletes are concerned? (I don't recall seeing it until 3.1.)

  • Link to RSS/Atom feed, relative, doesn't work in Firefox

    - by Adrian Smith
    I have a weird problem. I generate a HTML page, hosted let's say at http://www.x.com/stuff which contains <head> <link type="application/atom+xml" rel="alternate" href="/stuff/feed"/> .. </head> The result is: In IE7 all works well - you can click on the feed icon in the browser and the feed is displayed In Firefox, view source, click on the linked /stuff/feed and you see the source of the feed, so that works as expected In Firefox, view the page (not source), then click on the feed icon in the address bar, I get an error that it can't retrieve the URL feed://http//www.x.com/stuff/feed So the problem is, that it's appending feed:// to the front of the URL and then taking out the colon : after the http. I understand that feed: is HTTP anyway so perhaps the adding of that isn't a big problem. But anyway, the fact is, that URL Firefox generates out of my <link> tag doesn't work. I have considered making the URL absolute, but I haven't found any evidence that those URLs have to be absolute, nor can I understand why that would be the case. And for various reasons it would be inconvenient in my code to generate an absolute URL. I can do it if necessary but I would prefer to see proof (e.g. specification, or Mozilla bug report) that it's necessary before making my code messy What do you think? Does anyone know of any evidence that the URL should be absolute? Or am I doing something else wrong? It seems such a simple/obvious tag, where nothing could go wrong, but I can't get it to work.

  • KendoUI Mobile switch and datasource

    - by OnaBai
    I'm trying to have a list of items displayed using a listview, something like: <div data-role="view" data-model="my_model"> <ul data-role="listview" data-bind="source: ds" data-template="list-tmpl"></ul> </div> Where I have a view using a model called my_model and a listview where the source is bound to ds. My model is something like: var my_model = kendo.observable({ ds: new kendo.data.DataSource({ transport: { read: readData, update: updateData, create: updateData, remove: updateData }, pageSize: 10, schema: { model: { id: "id", fields: { id: { type: "number" }, name: { type: "string" }, active: { type: "boolean" } } } } }) }); Each item includes an id, a name (that is a string) and a boolean named active. The template used to render each element is: <script id="list-tmpl" type="text/kendo-tmpl"> <span>#= name # : #= active #</span> <input data-role="switch" data-bind="checked: active"/> </script> Where I display the name and (for debugging) the value of active. In addition, I render a switch bound to active. You should see something like: The problems observed are: If you click on a switch you will see that the value of active next to the name changes its value (as expected) but if then, you pick another switch, the value (neither next to name nor in the DataSource) is not updated (despite the value of the switch is correctly updated). The update handler in the DataSource is never invoked (not even for the first chosen switch and despite the DataSource for that first toggled switch is updated). You can check it in JSFiddle: http://jsfiddle.net/OnaBai/K7wEC/ How do I make that the DataSource gets updated and update handler invoked?

  • rapid application developement tools for very basic GUI apps

    - by Jurij
    I know there are many RAD platforms out there. Infact there are so many that I'm having a hard time finding out which one fits me best. What I want is a RAD tool that would allow me to define a database data model (make DB tables) and then create (view and edit) forms for the various tables. Data input, updating and various queries should be easy and GUI should generate automatically. I'd like to add some additional functionality by coding (such as various complex calculations on the data). I'm a programmer so I'm willing to learn to use a more complete, full-blown RAD solution if you can point me to it (NetBeans and RubyOnRails being the two such frameworks that I'd would probably be high on the list). I'm currently doing Windows Forms logistics apps in .NET. I've actually developed a very crude and basic version of what I need, but I just know that there are solutions out there that are much better and I'd benefit by knowing how to use them. So in short, the basic requirements: * database based data storage (SQLite if possible) * very automated GUI creation * desktop based (as in: not a web app) * extendable by coding * used for creating simple data entry, view & query apps. So basically something like Oracle Forms or DotNetMushroom Rapid Application Developer. But for .NET and SQLite if possible.
