  • ASP.MVC 2 RTM + ModelState Error at Id property

    - by Zote
    I have this classes: public class GroupMetadata { [HiddenInput(DisplayValue = false)] public int Id { get; set; } [Required] public string Name { get; set; } } [MetadataType(typeof(GrupoMetadata))] public partial class Group { public virtual int Id { get; set; } public virtual string Name { get; set; } } And this action: [HttpPost] public ActionResult Edit(Group group) { if (ModelState.IsValid) { // Logic to save return RedirectToAction("Index"); } return View(group); } That's my view: <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<Group>" %> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <% using (Html.BeginForm()) {%> <fieldset> <%= Html.EditorForModel() %> <p> <input type="submit" value="Save" /> </p> </fieldset> <% } %> <div> <%=Html.ActionLink("Back", "Index") %> </div> </asp:Content> But ModelState is always invalid! As I can see, for MVC validation 0 is invalid, but for me is valid. How can I fix it since, I didn't put any kind of validation in Id property? UPDATE: I don't know how or why, but renaming Id, in my case to PK, solves this problem. Do you know if this an issue in my logic/configuration or is an bug or expected behavior? Thank you

  • Using a helper method in a mailer that is defined in a controller

    - by Horace Loeb
    The helper method current_user is defined and made available as a helper in ApplicationController like this: class ApplicationController < ActionController::Base helper_method :current_user def current_user return @current_user if defined?(@current_user) @current_user = current_user_session && current_user_session.record end end My question is how I can use the current_user helper method in a mailer template (obviously it will always return nil, but I'm trying to render a partial that depends on it). Normally when I want to use helpers in a mailer, I do something like add_template_helper(SongsHelper), but since the helper is defined in a class instead of a module I'm not sure what to do

  • Optimizing encrypted column search

    - by Sung Meister
    I have a table called,tblClient with an encrypted column called SSN. Due to company policy, we encrypted SSN using a symmetric key (chosen over asymmetric key due to performance reasons) using a password. Here is a partial LIKE search on SSN declare @SSN varchar(11) set @SSN = '111-22-%' open symmetric key SSN_KEY decrypt by password = 'secret' select Client_ID from tblClient (nolock) where convert(nvarchar(11), DECRYPTBYKEY(SSN)) like @SSN close symmetric key SSN_KEY Before encryption, searching thru 150,000 records took less than 1 second. but with the mix of decryption, the same search takes around 5 seconds. What strategy can I apply to try to optimize searching thru encrypted column?

  • Safe non-tamperable URL component in Perl using symmetric encryption?

    - by Randal Schwartz
    OK, I'm probably just having a bad Monday, but I have the following need and I'm seeing lots of partial solutions but I'm sure I'm not the first person to need this, so I'm wondering if I'm missing the obvious. $client has 50 to 500 bytes worth of binary data that must be inserted into the middle of a URL and roundtrip to their customer's browser. Since it's part of the URL, we're up against the 1K "theoretical" limit of a GET URL. Also, $client doesn't want their customer decoding the data, or tampering with it without detection. $client would also prefer not to store anything server-side, so this must be completely standalone. Must be Perl code, and fast, in both encoding and decoding. I think the last step can be base64. But what are the steps for encryption and hashing that make the most sense?

  • 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.

  • 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!

  • 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?

  • 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.

  • Problem with ImageButton.setVisibility()

    - by Luis Lopez
    Hello guys! I'm having a problem when setting the visibility of two image buttons one on top of the other. The idea is to implement a play/pause control. The problem is that the only part where setting the visibility actually works is in the click listeners of the buttons. If I try to change it somewhere else nothing happens. Any idea why is this happening? Thanks in advance! playBtn.setOnClickListener(new OnClickListener() {//PLAY BUTTON LISTENER public void onClick(View v) { playBtn.setVisibility(ImageButton.GONE); pauseBtn.setVisibility(ImageButton.VISIBLE); mp.start(); }}); pauseBtn.setOnClickListener(new OnClickListener() {//PAUSE BUTTON LISTENER public void onClick(View v) { pauseBtn.setVisibility(ImageButton.GONE); playBtn.setVisibility(ImageButton.VISIBLE); mp.pause(); }}); final class SeekBarTask extends TimerTask { public SeekBarTask(int duration) { } @Override public void run() { if(seekBar.getProgress() = mp.getDuration()) {//IF SONG HAS FINISHED... pauseBtn.setVisibility(ImageButton.GONE);//THESE ONES playBtn.setVisibility(ImageButton.VISIBLE);//DOESN'T WORK mp.stop(); } else { seekBar.incrementProgressBy(100); } } }

  • ASP.NET Binding integer to CheckBox's Checked field

    - by Sung Meister
    I have a following ListView item template, in which I am trying to bind integer value to Checked property of CheckBox. IsUploaded value contains only 0 and 1... <asp:ListView ID="trustListView" runat="server"> <ItemTemplate> <asp:CheckBox ID="isUploadedCheckBox" runat="server" Checked='<%# Bind("IsUploaded") %>' /> </ItemTemplate> </asp:ListView> But ASP.NET complains that Exception Details: System.InvalidCastException: Sepcified cast is not valid Even though following code using DataBinder.Eval() works, I need to have a 2-way binding, thus need to use Bind(). <asp:CheckBox ID="isUploadedCheckBox2" runat="server" Checked='<%# Convert.ToBoolean( DataBinder.Eval(Container.DataItem, "IsUploaded"))) %>' /> How can I convert 0's and 1's to boolean using Bind()? [ANSWER] I have extended auto-generated type through partial class by adding a new property mentioned in the answer by Justin

  • 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?

  • How do I code a MVC3 Helper

    - by Mike Clarke
    I’ve just build my first Helper in MVC, it’s very basic and just displays a string where ever I use it. So it’s a .cshtml file in my App_Code folder, I think that is how it's supposed to be set up, with the following code in it, @helper DisplaySelect() { @:This text is coming from an helper class. } Now I am a wiz with helpers how do I make it do things. E.g.. say I want it to query the database and display something, I would normally do that work in my controller. How do I do that with helpers, do I create a helper controller and then treat the helper like a partial view??? Any help would be greatly appreciated. Cheers, Mike.

  • Eclipse plugin development for Eclipse

    - by Raven
    Hi, how do I start to develop a plugin for Eclipse? I need a tool which isn't out there yet for my further development... so my main concerns are: -How to add a perspective? -How to add menu items? -How to add a view into the "Show Views" menu? -How to add to the preference pane? -How do I get information, like * where is the workspace? * which files are open in the editor? * which projects are collapsed / expanded in the left projects view? * ..... -Which conventions (naming...) should I consider? -How to set up update site/deployment? Can you give me some hints, links, tutorials.... Dont get me wrong. I am using Eclipse RCP for developing stand alone apps for quite some time, so I am familiar with the techniques, but I never started to develop a plugin for Eclipse itself. Thanks

  • WinForms form freezes

    - by andrew
    On a form (F1) i have a button, from which if i create another form (lets call it F2) and show it there's no problem but i'd like to do something like this Some thread in my app is running a connection and listens for messages from a server. when a message arrives, my main form is registered to get an event that runs a function. From that function i'm trying to create and show the F2 type form (empty, nothing modified in it): it shows it but then it freezes my application. more exactly: public partial class Form1 : Form { public Form1() { InitializeComponent(); ConnectionManagerThread.getResponseListener().MessageReceived += Form1_OnMessageReceived; } private void Form1_OnMessageReceived(object sender, MessageEventArgs e) { Form2 f2 = new Form2(); f2.Show(); } }

  • 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...

  • Django LFS - custom views

    - by owca
    For all those ligthning fast shop users. I'm trying to implement my own first page view that will list all products from shop ( under '/' address). So I have a template : {% extends "lfs/shop/shop_base.html" %} {% block content %} <div id="najnowsze_produkty"> <ul> {% for obj in objects %} <li> {{ obj.name }} </li> {% endfor %} </ul> </div> {% endblock %} and then I've edited main shop view : from lfs.catalog.models import Category from lfs.catalog.models import Product def shop_view(request, template_name="lfs/shop/shop.html"): products = Product.objects.all() shop = lfs_get_object_or_404(Shop, pk=1) return render_to_response(template_name, RequestContext(request, { "shop" : shop, "products" : products })) but it just shows nothing. When I do Product.objects.all() query in shell I get results. Any ideas what could cause the problem ? Maybe I should filter products with 'active' status only ? But I'm not sure if it can influence all objects in any way.

  • 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!

  • Apache deflate with chucked encoding

    - by hoodoos
    I'm expiriencing some problem with one of my data source services. As it says in HTTP response headers it's running on Apache-Coyote/1.1. Server gives responses with Transfer-Encoding: chunked, here sample response: HTTP/1.1 200 OK Server: Apache-Coyote/1.1 Content-Type: text/xml;charset=utf-8 Transfer-Encoding: chunked Date: Tue, 30 Mar 2010 06:13:52 GMT And problem is when I'm requesting server to send gzipped request it often sends not full response. I recieve response, see that last chunk recived, but then after ungzipping I see that response is partial. So my question is: is it common apache issue? maybe one of it's mod_deflate plugins or something? Ask questions if you need more info. Thanks.

  • My Core Animation block isn't working as I'd expect

    - by Alex Reynolds
    I have a UIView called activityView, which contains two subviews activityIndicator and cancelOperationsButton. These views are embedded in a XIB and wired up to my view controller. I have two methods that deal with activating (showing) and deactivating (hiding) these two subviews: - (void) enableActivityIndicator { [activityIndicator startAnimating]; [cancelOperationsButton setHidden:NO]; } - (void) disableActivityIndicator { [activityIndicator stopAnimating]; [cancelOperationsButton setHidden:YES]; } By themselves, these two methods work fine. To give this a bit of polish, I'd like to add an animation that fades these subviews in and out: - (void) enableActivityIndicator { [activityIndicator startAnimating]; [cancelOperationsButton setHidden:NO]; [UIView beginAnimations:@"fadeIn" context:nil]; [UIView setAnimationDelay:0.0f]; [UIView setAnimationDuration:1.0f]; [UIView setAnimationCurve:UIViewAnimationCurveEaseIn]; activityView.alpha = 1.0f; [UIView commitAnimations]; } - (void) disableActivityIndicator { [UIView beginAnimations:@"fadeOut" context:nil]; [UIView setAnimationDelay:0.0f]; [UIView setAnimationDuration:1.0f]; [UIView setAnimationCurve:UIViewAnimationCurveEaseOut]; activityView.alpha = 0.0f; [UIView commitAnimations]; [activityIndicator stopAnimating]; [cancelOperationsButton setHidden:YES]; } But the animations are not working — the subviews just show up or disappear without the parent view's alpha property having an effect on transparency. How should I write these methods to get the fade-in, fade-out effect I am after?

  • ActionScript 3 class over several files - how?

    - by Poni
    So, how do we write a class over several files in action script 3? In C# there's the "partial" keyword. In C++ it's natural (you just "#include ..." all files). In Flex 3, in a component, you add this tag: <mx:Script source="myfile.as"/>. How do I split the following class into several files; package package_path { public class cSplitMeClass { public function cSplitMeClass() { } public function doX():void { // .... } public function doY():void { // .... } } } For example I want to have the doX() and doY() functions implemented in another ".as" file. Can I do this? And please, don't tell me something like "a good practice is to have them in one file" :)

  • 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?
