  • Comparing lists of objects and update

    - by user2915962
    I have a view, passing a LIST of Originals to this method. Before the post happened, i changed some of the properties. I now receive the updated list as a parameter in my method and would like to update the database with these new values. [HttpPost] public ActionResult NewValue(Page model) { var ListOfOriginals = Session.Query<Original>().ToList(); //GETS the objects i want to update listOfOriginals = Model.Pages // Model.page is the new list containing the updated values RavenSession.SaveChanges(); return RedirectToAction("Index"); } When i debug, i can see that listOfOriginals gets the new values. The problem is that i dont know how to update the RavenDB whith these new values. I tried adding this: Session.Store(listOfOriginals) before the SaveChanges() but that resulted in an error. Maybe there is a much better way of doing this?

  • C#: Replicating keyboard shortcuts in textbox, how do I prevent the beep sound caused by alt key pre

    - by Michael Johnson
    I'm creating a routine that allows the user to replicate keyboard shortcuts into a textbox for 'custom keyboard shortcuts' customization, but everytime the alt key is pressed with another letter, it produces another sound. I'm capturing the keys in the textbox_keydown event to parse the modifiers + other keys into a readable Shift + A or Ctrl + Shift + B manner into that very same textbox. Should I be doing this in a different event like textbox_previewkey instead of textbox_keydown? How can I prevent the alt modifier key + a letter or number causing the Beep sound? the textbox is just a normal .net 3.5 textbox with the only edited properties of it being the ReadOnly property to false. Is there a better way I could re-do this? I'm currently just checking that if any modifiers keys are pressed and then + a-z or 0-9, then to go ahead and input the appropriately pressed keys into that same textbox like Shift + A or Ctrl + Shift + Y.

  • Flex - weird display behavior on large number of Canvas

    - by itarato
    Hi, I have a Flex app (SDK 3.5 - FP10) that does mindmap trees. Every node is a Canvas (I'm using Canvas specific properties so I needed it). It has a shadow effect, background color and some small ui element on it (like icons, texts...). It works perfectly until it goes over ~700 nodes (Canvas). Over that number it shows grey rectangles: http://yfrog.com/bhw2pj . If I turn off the DropShadowFilter effect for the Canvas, they are also gone, so I assume it's a DropShadowFilter problem: http://yfrog.com/2d9y8j . The effect is simple: private static var _nodeDropShadow:DropShadowFilter = new DropShadowFilter(1, 45, 0x888888, 1, 1, 1); _backgroundComp.filters = _nodeDropShadow; Is it possible that Flex can't handle that much? Thanks in advance

  • Retain Count Question: Some Guidance, Please

    - by yar
    [I'm sure this is not odd at all, but I need just a bit of help] I have two retain properties @property (nonatomic, retain) NSArray *listContent; @property (nonatomic, retain) NSArray *filteredListContent; and in the viewDidLoad method I set the second equal to the first (so now the retainCount is two, I think): self.filteredListContent = self.listContent; and then on every search I do this self.filteredListContent = [listContent filteredArrayUsingPredicate:predicate]; I thought I should do a release right above this assignment -- since the property should cause an extra retain, right? -- but that causes the program to explode the second time I run the search method. The retain counts (without the extra release) are 2 the first time I come into the search method, and 1 each subsequent time (which is what I expected, unfortunately). Some guidance would help, thanks! Is it correct to not release?

  • In what package should a "Settings" class be?

    - by Tom
    I've in the middle of building an application but found myself too easily creating new packages without keeping the project's structure in mind. Now, I'm trying to redo the whole project structure on paper first. I am using a Settings class with public properties, accessed as settings for several other classes around the project. Now, since this Settings class applies for the whole project, I am unsure if it should be packaged and if so, in what kind of package should it exist? Or should it be in the root (the default package) with the main application class? I've been thinking about putting it in my utils package, then again I don't think it really is an utlity. Any strategies on how to decide on such package structure for example for a Settings class?

  • SQLAlchemy introspection of ORM classes/objects

    - by Adam Batkin
    I am looking for a way to introspect SQLAlchemy ORM classes/entities to determine the types and other constraints (like maximum lengths) of an entity's properties. For example, if I have a declarative class: class User(Base): __tablename__ = "USER_TABLE" id = sa.Column(sa.types.Integer, primary_key=True) fullname = sa.Column(sa.types.String(100)) username = sa.Column(sa.types.String(20), nullable=False) password = sa.Column(sa.types.String(20), nullable=False) created_timestamp = sa.Column(sa.types.DateTime, nullable=False) I would want to be able to find out that the 'fullname' field should be a String with a maximum length of 100, and is nullable. And the 'created_timestamp' field is a DateTime and is not nullable.

  • RIA Services - Two entity models share an entity name

    - by Alex
    I have two entity models hooked up to two different databases. However, the two databases both have a table named 'brand', for example. As such, there is a naming conflict in my models. Now, I've been able to add a namespace to each model, via Custom Tool Namespace in the model's properties, but the generated code in my Silverlight project will try to use both namespaces, and come up with this, Imports MyProject.ModelA Imports MyProject.ModelB Public ReadOnly Property brands() As EntitySet(Of brand) Get Return MyBase.EntityContainer.GetEntitySet(Of brand) End Get End Property giving me this exception: 'Error 1 'brand' is ambiguous, imported from the namespaces or types 'MyProject.ModelA,MyProject.ModelB'. Has anyone had experience with naming conflicts like this using RIA services? How did you solve it?

  • How to create relationship between two tables with revisions using Entity Framework

    - by Chris Ridenour
    So I am in the process of redesigning a small database (and potentially a much larger one) but want to show the value of using revisions / history of the business objects. I am switching the data from Access to MSSQL 2008. I am having a lot of internal debate on what version of "revision history" to use in the design itself - and thought I had decided to add a "RevisionId" to all tables. With this design - adding a RevisionId to all tables we would like tracked - what would be the best way to create Navigational Properties and Relationships between two tables such as | Vendor | VendorContact | where a Vendor can have multiple contacts. The Contacts themselves will be under revision. Will it require custom extensions or am I over thinking this? Thanks in advance.

  • "Dynamic" java validation framework?

    - by pihentagy
    AFAIK JSR-303 is the standard bean validation system. I don't know whether it could do validations like this (I guess no): if an object has a deleted flag set, you cannot modify the object you cannot change the start date property, after the date is passed you cannot decrease some integer properties in the bean So how can I handle validations, which depend on the previous state of an object? I would like to solve problems like that in hibernate3.5 - spring3 - JPA2 environment. Thanks My solution was to mess with hibernate, reload the object to see the old state (after evicting the new object). This time I need some smarter solution...

  • Updating Silverlight with data. JSON or WCF?

    - by Alastair Pitts
    We will be using custom Silverlight 4.0 controls on our ASP.NET MVC web page to display data from our database and was wondering what the most efficient method was? We will be having returned values of up to 100k records (of 2 properties per record). We have a test that uses the HTML Bridge from Javascript to Silverlight. First we perform a post request to a controller action in the MVC web app and return JSON. This JSON is then passed to the Silverlight where it is parsed and the UI updated. This seems to be rather slow, with the stored procedure (the select) taking about 3 seconds and the entire update in the browser about 10-15sec. Having a brief look on the net, it seems that WCF is another option, but not having used it, I wasn't sure of it's capability or suitability. Does anyone have any experiences or recommendations?

  • Iterate over a dict or list in Python

    - by Chris Dutrow
    Just wrote some nasty code that iterates over a dict or a list in Python. I have a feeling this was not the best way to go about it. The problem is that in order to iterate over a dict, this is the convention: for key in dict_object: dict_object[key] = 1 But modifying the object properties by key does not work if the same thing is done on a list: # Throws an error because the value of key is the property value, not # the list index: for key in list_object: list_object[key] = 1 The way I solved this problem was to write this nasty code: if isinstance(obj, dict): for key in obj: do_loop_contents(obj, key) elif isinstance(obj, list): for i in xrange(0, len(obj)): do_loop_contents(obj, i) def do_loop_contents(obj, key): obj[key] = 1 Is there a better way to do this? Thanks!

  • Obtaining reference to Class instance by string name - VB.NET

    - by Jeff Williams
    Is it possible using Reflection or some other method to obtain a reference to a specific class instance from the name of that class instance? For example the framework for the applications i develop heavily uses public class instances such as: Public bMyreference as MyReference = new MyReference Then throughout the application bMyReference is used by custom controls and code. One of the properties of the custom controls is the "FieldName" which references a Property in these class instances (bMyReference.MyField) as a string. What i would like to be able to do is analyze this string "bMyReference.MyField" and then refer back to the actual Instance/Property. In VB6 I would use an EVAL or something simular to convert the string to an actual object but this obviously doesn't work in VB.net What I'm picturing is something like this Dim FieldName as String = MyControl.FieldName ' sets FielName to bMyReference.MyField Dim FieldObject() as String = FieldName.Split(".") ' Split into the Object / Property Dim myInstance as Object = ......... ' Obtain a reference to the Instance and set as myInstance Dim myProperty = myInstance.GetType().GetProperty(FieldObject(1))

  • Huge AS 3.0 Export Frame

    - by goorj
    I am creating a very simple flash animation with no code or complex effects, just text and simple tweens (Flash CS5) But I have problems reducing the size of my swf. From the generated size report, it looks like it has to do with fonts and/or exported actionscript classes. The frame with AS 3.0 Classes is over 100K, and even though I am only using one fonts, the same characters are embedded/exported multiple times My questions are: Do embedding of mixed TLF/Classic text (or mixing other text properties, spacing/kerning etc) require the same characters to be embedded twice? Do text transformations on TLF text (rotation and different transformations not available in classic text) require embedding of ("internal") AS3 classes that will increase the size of the .swf? (even though none of these classes are explicitly used by me, there are no scripts in the fla project) I have tried removing all the text instances one by one, and at one point, the swf is reduced to only 5-6K, but I am not able to pinpoint exactly what causes the ballooning of the swf

  • Using asp.net mvc model binders generically

    - by Sean Chambers
    I have a hierarchy of classes that all derive from a base type and the base type also implements an interface. What I'm wanting to do is have one controller to handle the management of the entire hierarchy (as the actions exposed via the controller is identical). That being said, I want to have the views have the type specific fields on it and the model binder to bind against a hidden field value. something like: <input type="text" name="model.DerivedTypeSpecificField" /> <input type="hidden" name="modelType" value="MyDerivedType" /> That being said, the asp.net mvc model binders seem to require the concrete type that they will be creating, because of that reason I would need to create a different controller for every derived type. Has anyone does this before or know how to manipulate the model binder to behave in this way? I could write my own model binder, but I'm not wanting anything past the basic model binding behavior of assign properties and building arrays on the target type. Thanks!

  • PHP MVC correct usage

    - by Ratt
    What is the correct (recommended method) for passing information to a view in a MVC environment. Currently we use Zend Framework, where we write classes to handle specific things EG a Book class with a save and load method to retrieve info from the DB, which is called from a particular nameAction(). What I would like to know is what is the best way to pass this information to the view, in some cases we do $this-view-book_name = $book-getBookName(); and in other cases we do the following $this-view-book = $book; OR $this-view-books = Book_Manager::getAllBooks(); and then access the object(s) properties in the view. Information on-line suggests we try limit what access a view has to information, i.e pass them only what they need and in some cases people say its ok to pass stuff through as long as nothing is done to that information.

  • A pragmatic view on private vs public

    - by Denis Gorbachev
    Hello everybody! I've always wondered on the topic of public, protected and private properties. My memory can easily recall times when I had to hack somebody's code, and having the hacked-upon class variables declared as private was always upsetting. Also, there were (more) times I've written a class myself, and had never recognized any potential gain of privatizing the property. I should note here that using public vars is not in my habit: I adhere to the principles of OOP by utilizing getters and setters. So, what's the whole point in these restrictions?

  • Are view models used in rails?

    - by Valentin Vasilyev
    I'm starting to develop a small application in ruby on rails and many questions arise. I should say that I have about 1 year of experience with ASP.NET MVC and feel at home with models views and controllers. I've been using view models extensively (with the help of AutoMapper) and now wondering if view models are used similarly in rails camp. From various examples (rails casts mainly) I've gathered that it is common to either combine data from multiple models right in your view (which is frowned upon in ASP.NET MVC), or to use virtual attributes on models to obtain "missing" data. I know that business model should not be modelled after UI needs, for example there should not be a 'password confirm' property in your model, this should be a view model property. Rails virtual properties seem to violate this principle. How is it done in rails? Thanks.

  • ASP.NET validation controls

    - by mehmet6parmak
    Hi All, I want to use Validation Controls but I dont want them to show their Error Messages when invalid data exist. Instead I'm going to iterate through the validation controls and show error messages inside my little ErrorMessage Control for (int i = 0; i < Page.Validators.Count; i++) { if (!Page.Validators[i].IsValid) { divAlert.InnerText = Page.Validators[i].ErrorMessage; return false; } } I'm doing this because i have little space to show the error message. You can ask why are you using validation control if you dont want to show them My asnwer is "I use them for validation logic they handle" I looked the properties of the validation controls and cant find something that wil help me doing this. Any Idea? Thanks

    I'm a complete newb to MDX / OLAP, "data warehousing" in general. I have the following MDX query and would like my results to display the month's number (1 = January, 12 = December). Luckily, the cube creator create a member property named "Month Number Of Year" When I try to run the query, I get the following... "Query (4, 8) The function expects a tuple set expression for the 1 argument. A string or numeric expression was used." Any suggestions for fixing this? Thanks!

  • JQuery Selector - Select this, not that?

    - by JasonS
    Hi, I have created a script which is surprisingly working. (I do not do much JavaScript) What I have is a load of images listed within a div. These images are hidden. JQuery gets the properties of the images and puts them into an array. When the body is clicked, the background image of the page changes. This works nicely. However, I now have a problem. There are several elements which I shouldn't change the background when they are clicked. Namely, navigation, footer and caption. How do I create a selector which makes the body clickable, yet ignores clicks on the above 3 div's?

  • Cannot edit ColumnDefinitions property in Visual Studio WPF application, ellipsis are invisible!

    - by SLC
    I have a window that looks like this: <Window x:Class="MyWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="My Title" Height="300" Width="300" ResizeMode="NoResize" SizeToContent="Height" WindowStartupLocation="CenterOwner"> <DockPanel> <Grid x:Name="MyGrid" DockPanel.Dock="Top" Margin="10"> </Grid> </DockPanel> </Window> Pretty simple. The instructions I am following suggest that if I click the item, the properties window will appear (it does), and then I can click ColumnDefinitions (which is a Collection) to bring up the Collection Editor and add some columns. However, the ColumnDefinitions property looks like this: The ColumnDefinitions ellipsis you'd normally press is gone, or invisible, or something. Any idea why?

  • Using colon syntax and variables in Sass

  • What is the algorithm used by the memberwise equality test in .NET structs?

    - by Damian Powell
    What is the algorithm used by the memberwise equality test in .NET structs? I would like to know this so that I can use it as the basis for my own algorithm. I am trying to write a recursive memberwise equality test for arbitrary objects (in C#) for testing the logical equality of DTOs. This is considerably easier if the DTOs are structs (since ValueType.Equals does mostly the right thing) but that is not always appropriate. I would also like to override comparison of any IEnumerable objects (but not strings!) so that their contents are compared rather than their properties. This has proven to be harder than I would expect. Any hints will be greatly appreciated. I'll accept the answer that proves most useful or supplies a link to the most useful information. Thanks.

  • Stack trace with incorrect line number

    - by adrianbanks
    Why would a stack trace show "line 0", but only for one frame in the stack trace? eg. ... at System.Data.SqlClient.SqlCommand.ExecuteDbDataReader(CommandBehavior behavior) at System.Data.Common.DbCommand.System.Data.IDbCommand.ExecuteReader() at My.LibraryA.Some.Method():line 16 at My.LibraryB.Some.OtherMethod():line 0 at My.LibraryB.Some.Method():line 22 at My.LibraryA.Some.Method():line 10 Background: I have an application that is failing with an exception, and is logging a stack trace to its log file. When the applciation was built, all assemblies were compiled with full debug info (Project Properties - Build - Advanced - Debug Info - Full), and so PDB files were generated. To help me diagnose where the error is coming from, I dropped the PDB files into the application's bin directory, and reproduced the exception. All line numbers for each stack frame look correct, with the exception of one which displays "line 0" as its source.
