  • How to set ActiveModel::Base.include_root_in_json to false?

    - by Mark L
    I'm using Rails 3 w/ Mongoid, (so no ActiveRecord). Mongoid uses ActiveModel's "to_json" method, and by default that method includes the root object in the JSON (which I don't want). I've tried putting this in an initializer: ActiveModel::Base.include_root_in_json = false But get the error uninitialized constant ActiveModel::Base Any ideas how I can change this? I changed the default directly in the source-code and it worked fine, but obviously I'd like to do it properly. The variable is defined at the top of this file: Github - activemodel/lib/active_model/serializers/json.rb From the docs: "The option ActiveModel::Base.include_root_in_json controls the top-level behavior of to_json. It is true by default."

  • Creating blob properties with Entity Framework 4?

    - by David Veeneman
    I am creating an EF4 model-first application with a WPF UI. One of the controls on my UI is a RichTextDocument, which outputs a WPF FlowDocument. I can either serialize the FlowDocument to a byte array, or extract its XAML markup as a string. I would prefer to use binary serialization, if I can. Here are my questions: If I serialize to a byte array, how do I specify an entity property as a byte array in the EDM Designer? If I extract a XAML markup string, can I specify that the EDM Designer create the corresponding database column as a nvarchar(max) column? As to the second question, I assume I could always manually edit the MyModel.edmx.sql file to change the data type from nvarchar(4000) to nvarchar(max) before executing it, but I would like to know if it can be done in the Designer. Thanks for your help.

  • MVC repository pattern design decision

    - by bradjive
    I have an asp .net MVC application and recently started implementing the repository pattern with a service validation layer, much like this. I've been creating one repository/service for each model that I create. Is this overkill? Instead, should I create one repository/service for each logical business area that provides CRUD for many different models? To me, it seems like I'm either cluttering the project tree with many files or cluttering a class with many methods. 6 one way half dozen the other. Can you think of any good arguments either way?

  • HTML5 video tag in chrome - wmv

    - by elcuco
    Hi Al, I need to make a page which displays a video. Firefox and and Opera support the OGG format, no problem there. Chrome is ... "stupid" and does not recognize OGG. Does Chrome on Windows know how to handle WMV? I already have them encoded, and no I cannot recode new videos since the media is limited in spaced (CDROM). My code currently looks like this (and not working in chrome) <video controls> <source codecs="theora, vorbis" media="video/ogg" src="video.ogv" /> <source media="video/x-ms-wmv" src="video.wmv" /> Please install a new browser, or just get out </video> Note that I am missing a codec entry, does anyone know what I need to put there?

  • Silverlight Project - Slide-in and out Panel - How?

    - by user118190
    I don't know what exactly this feature is, but I would like to simulate this in my Silverlight project. I am a C# developer and am moving to Silverlight and Expression Studio (Blend) for richer UX. Let's say I have some user controls and would like them to come into the screen (slide-in and out) as shown in the following site I found: http://www.templatemonster.com/silverlight-templates/28722.html On the menu, as one clicks on the menu item, the 'screen' slides to the left and then a new 'screen' slides in from the left to right. I really want to learn this stuff, but don't know what these 'features' are called? For example what are these 'screens' called in the xaml world? Also, what is the 'slide-in/out' called in the xaml world? Can someone point me to a good article/whitepaper? Thanks in advance for any advice.

  • Workaround for UpdateSourceTrigger LostFocus on Silverlight Datagrid?

    - by Dave Lowther
    I have a Silverlight 2 application that validates data OnTabSelectionChanged. Immediately I began wishing that UpdateSourceTrigger allowed more than just LostFocus because if you click the tab without tabbing off of a control the LINQ object is not updated before validation. I worked around the issue for TextBoxes by setting focus to another control and then back OnTextChanged: Private Sub OnTextChanged(ByVal sender As Object, ByVal e As TextChangedEventArgs) txtSetFocus.Focus() sender.Focus() End Sub Now I am trying to accomplish the same sort of hack within a DataGrid. My DataGrid uses DataTemplates generated at runtime for the CellTemplate and CellEditingTemplate. I tried writing the TextChanged="OnTextChanged" into the TextBox in the DataTemplate, but it is not triggered. Anyone have any ideas?

  • C++ Direct 2D How To Resize ID2D1Bitmap

    - by Nkosi Dean
    I'm making myself a simple GUI library for a game I'm making and each control needs to have a Bitmap to draw to when the control needs redrawing. When it does not need to be redrawn, it will have an already made bitmap ready to display to the screen. Since controls can be resized, this Bitmap also needs to be resized so the control can be fully drawn into it properly. How can I achieve this since it does not appear to be a Resize method to resize a bitmap, unlike an ID2D1HwndRenderTarget, which can be resized?

  • Replace CAPICOM with .NET, validate certificate

    - by Zaky
    Hi My component is responsible for downloading files from the server. As part of file validation I have used CAPICOM (SignedCode object) to validate if a certificate contains a specific string and call to Validate method of the SignedCode object. In case the file contains certificate without a requested string in the name, user was prompted if he trust this file. Since CAPICOM going to be deprecated by Microsoft, I need to implement these logic using .NET libraries. How I can get the same functionality using .NET libraries? Is there any example on the web? Thanks Zaky

  • [C#/WPF] Combo box Item source = ObservableCollection & I need a '-None-' dummy entry at the top

    - by James
    I have a combo box using an observable collection as a datasource and I want a "dummy" value of "None" as the first item in the box as it controls filters against other data sources. Other databound objects also use the same observable collection so adding a "None" value directly to the datasource is not possible as I dont want, for example, my datagrids having a "none" in them. Also I'd rather avoid filters to just remove the "none" value for those that do not use it, as I'd like the observable collection to direclty reflect the database data; if at all possible. I'd also like to avoid having one observable collection per databound control. What I'm really after is a was to put a, non data bound, first entry into a combobox while also having the item source pointed at an obervable collection. Thanks

  • WPF binding Ancestor

    - by JerryVienna
    Hi Experts, I have problems with bindings. I want to use a UserControl (Intellibox from codeplex) but I only get error messages in the output window. Basically I have window grid ... stuff ... usercontrol (self written) ... stuff ... usercontrol (IntelliBox) In the Output window I get following stuff: System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='System.Windows.Controls.UserControl', AncestorLevel='1''. BindingExpression:Path=ShowResults; DataItem=null; target element is 'Popup' (Name='IntelliboxPopup1'); target property is 'IsOpen' (type 'Boolean') The binding in the IntelliBox control is defined as follows: {Binding Path=ShowResults, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}} I guess there is a problem, cause the nesting withing usercontrols - how to I get this error fixed? Thanks!

  • DataTrigger to make WPF Button inactive until TextBox has value

    - by JohnB
    I want the Button control's property to be IsEnabled="False" until a value is entered into a TextBox in the Window. Code so far: <Button Content="Click Me" Name="ClickMe" VerticalAlignment="Top" Click="ClickMe_Click"> <Button.Style> <Style> <Style.Triggers> <DataTrigger Binding="{Binding ElementName=textBox, Path=Length}" <!-- or even: Binding="{Binding Path=textBox.Length}" --> Value="0"> <Setter Property="Button.IsEnabled" Value="false" /> </DataTrigger> </Style.Triggers> </Style> </Button.Style> </Button> Also, is it possible to have this Button control's IsEnabled property be based on 3 different TextBox controls all having values?

  • Java SWIFT Library

    - by jkl
    I'm looking for a Java library for SWIFT messages. I want to parse SWIFT messages into an object model validate SWIFT messages (including SWIFT network validation rules) build / change SWIFT messages by using an object model Theoretically, I need to support all SWIFT message types. But at the moment I need MT103+, MT199, MT502, MT509, MT515 and MT535. So far I've looked at two libraries AnaSys Message Objects (link text) Datamation SWIFT Message Suite (link text) Both libraries allow to accomplish the tasks mentioned above but in both cases I'm not really happy. AnaSys uses a internal XML representation for all SWIFT messages which you need to know in order to access the fields of a message. And you need to operate on the DOM of the XML representation, there is no way to say "get the contents of field '50K' of the SWIFT message". And the Datamation library seems to have the nicer API but does not find all errors. So does anyone know other SWIFT libraries to use?

  • How to convert Silverlight XAML to Resource dictionary in Silverlight 2

    - by Vecdid
    I am looking for the quickest and easiest way to combine two silverlight projects. Once has controls all in Silverlight XAML the other is template driven and uses a template based on a Silverlight resource dictionary. I am looking for some advice and resources on the best and quickest way to do this. One project is based on this: Silverlight Image Slider http://www.silverlightshow.net/items/Image-slider-control-in-Silverlight-1.1.aspx the other project is based on this: Open Video Player http://www.openvideoplayer.com/ I need to move the slider into the player, but the player uses a template and I just don't get how to merge the two as I do not understand resource dictionaries as they are applied to the player. We have completely gutted and made each proiject do what we want, but heck if I can figure out how to combine them.

    I am using Microsoft WPF datagrid. I have noticed a strange behavior with WPF datagrid DataGridTemplateColumn. When you use the templateColumn in the grid and the template column contains some controls when you tab from the previous column the focus is not automatically given to the first element declared in the template column. The foucs is initally set on the border of the template column and when we tab of once agin the focus goes to the first column. Any workaround for this issue. How can i set the focus to go the first element in the template column of the datagrid when i tab off.

  • MPMoviePlayerController fullscreen quirk in iPad

    - by hgpc
    I want to show a MPMoviePlayerController in a view controller and let the user toggle full screen with the default controls, like the YouTube app. I'm using the following code in a bare-bones example: - (void)viewDidLoad { [super viewDidLoad]; self.player = [[MPMoviePlayerController alloc] init]; self.player.contentURL = theURL; self.player.view.frame = self.viewForMovie.bounds; self.player.view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; [self.viewForMovie addSubview:player.view]; [self.player play]; } This works well until the user makes the video full screen, rotates the device and taps on the screen. The status bar is shown in the wrong position, as shown in the screenshot below. http://yfrog.com/5fimg0006ryp I'm working with the template Tab Bar Application for iPad. I've only added the viewDidLoad above, the view variables and an UIView in the XIB to show the movie player. What am I doing wrong?

  • iPad/iPhone duplicate view and resize?

    - by MidnightLightning
    I'm working on an app that is similar to a Presentation application (Keynote/Powerpoint) for the iPad, that will use the VGA adapter to present on screen. However, if the presenter is using the external display for the presentation, I'm wondering if it's possible to have a miniature version of what's on the external display show up on the main iPad display (along with the presentation controls, which will take up most of the screen). In other words, I'm looking for a way with the iPhone SDK to "bake" the contents of a View (which will contain various Images and Labels in various locations) to an image (or some other static storage), resize it, and re-display it in another view. It would need to be smaller (since I don't want the 1024x768 external display to completely overlay the iPad's main display, only a corner of it), and either live-updating (literally an instance of the other View, just scaled), or be able to be refreshed, such that when updating the external display, the "picture in picture" version of itself would be updated too.

  • WPF MVVM: TextBox and default Button binding does update too late

    - by Sam
    I've got a simple WPF dialog with these two controls: <TextBox Text="{Binding MyText}"/> <Button Command="{Binding MyCommand}" IsDefault="True"/> Now, when I enter some text in the TextBox and click the button using the mouse, everything works like expected: the TextBox will set MyText and MyCommand is called. But when I enter some text and hit enter to "click" the default button, it does not work. Since on hitting enter the focus does not leave the TextBox, the binding will not be refresh MyText. So when MyCommand is called (which works), MyText will contain old data. How do I fix this in MVVM? In classic code-behind I probably just would call "MyButton.Focus()" in the MyCommand handler, but in MVVM the MyCommand handler does know nothing about the button. So what now`?

  • Encryption Product Keys : Public and Private key encryption

    - by Aran Mulholland
    I need to generate and validate product keys and have been thinking about using a public/private key system. I generate our product keys based on a client name (which could be a variable length string) a 6 digit serial number. It would be good if the product key would be of a manageable length (16 characters or so) I need to encrypt them at the base and then distrubute the decryption/validation system. As our system is written in managed code (.NET) we dont want to distribute the encryption system, only the decryption. I need a public private key seems a good way to do this, encrypt with the one key that i keep and distribute the other key needed for decrpytion/verification. What is an appropriate mechanism to do this with the above requirements?

  • Where are the Entity Framework t4 templates for Data Annotations?

    - by JK
    I have been googling this non stop for 2 days now and can't find a single complete, ready to use, fully implemented t4 template that generates DataAnnotations. Do they even exist? I generate POCOs with the standard t4 templates. The actual database table has metadata that describes some of the validation rules, eg not null, nvarchar(25), etc. So all I want is a t4 template that can take my table and generate a POCO with DataAnnotations, eg public class Person { [Required] [StringLength(255)] public FirstName {get;set} } It is a basic and fundamental requirement, surely I can not be the first person in the entire world to have this requirement? I don't want to re-invent the wheel here. Yet I haven't found it after search high and low for days. This must be possible (and hopefully must be available somewhere to just download) - it would be criminally wrong to have to manually type in these annotations when the metadata for them already exists in the database.

  • UserControl Focus Issue - Focus() sometimes returns false

    - by Craigger
    I have a user control that behaves similar to a tab control. The tab headers are UserControls that override Paint events to make them look custom. In order to leverage the Validating events on various controls on our tab pages, when the user clicks on the tab headers, we set the Focus to the TabHeader user control. I've noticed that Control.Focus() returns false sometimes but the documentation does not say why Control.Focus() will ever return false other than that the control can't receive focus. But I don't know why. Here's what i see. If my TabHeader UserControl does not contain any subcontrols, and I call myControl.Focus() from the MouseClick event, focus returns true. If my TabHeader UserControl contains a subcontrol, and I call myControl.Focus() from the MouseClick event, focus returns false. If my TabHeader UserControl contains a subcontrol, and I call myControl.subControl.Focus() from the myControl.MouseClick event, focus returns true. Can someone explain this?

I want to find the parent node of the drop target. How do I do it?

  • How can I set initial values when using Silverlight DataForm and .Net RIA Services DomainDataSource?

    - by TheDuke
    I'm experimenting with .Net RIA and Silverlight, I have a few of related entities; Client, Project and Job, a Client has many Projects, and a Project has many Jobs. In the Silverlight app, I'm uisng a DomainDataSource, and DataForm controls to perform the CRUD operations. When a Client is selected a list of projects appears, at which point the user can add a new project for that client. I'd like to be able to fill in the value for client automatically, but there doesn't seem to be any way to do that, while there is an AddingNewItem event on the DataForm control, it seems to fire before the DataForm has an instance of the new object and I'm not sure trawling through the ChangeSet from the DomainDataSource SubmittingChanges event is the best way to do this. I would of thought this would of been an obvious feature... anyone know the best way to achieve this functionality?

  • JSF 2 equivalent of tomahawk subform

    - by digitaljoel
    I have an existing JSF 1.2 app that was a portlet running on glassfish v2. I'm converting it to a webapp running on glassfish v3. The app uses tomahawk subforms in several areas. Tomahawk has not been update for JSF 2, which is what ships with glassfish v3. We would like to update our app to JSF 2. Is there a JSF 2 equivalent to tomahawk's subform? I know one option would be to change all of the subforms to be ajax enabled and use the execute attribute to specify which controls take part in the form submission, but would like to make this as straight across as I can without modifying existing functionality if I can. So, lacking a tomahawk subform substitute, is there any way to specify partial form submission for non ajax events?
