  • How to combine mvc2 client side validation with other client side validation?

    - by Andrey
    I have a page using mvc2 with client side validation. The client side validation is provided by Microsoft Ajax mvc validation script. This does very well to validate all fields that are related to the model. I also have fields that are never sent to the server such as the confirm password value, and the accept agreement. For these fields i need pure client side validation. I created the javascript to do this, but am now having a hard time integrating the two validatiosn together. I was hoping that i could do something like add another error to an array, or set the page manually to not valid to make sure that the user cannot submit. Basically follow the same approach that i would with normal asp.net validation. I can't find anything like that. In all examples validators are discussed that are connected to parts of the model. What is my best approach here?

    - by Andrey Khataev
    I've found that in order to use PRISM's classes in XAML you need to import namespace in that way: xmlns:cal="http://www.codeplex.com/CompositeWPF" this way is new to me, so I wanted to know, how hyperlink could be alias of usual notation of namespace import? so the intellisence knows in which assembly it should search this component? Thanks!

  • Hibernate one-to-one mapping

    - by Andrey Yaskulsky
    I have one-to-one hibernate mapping between class Student and class Points: @Entity @Table(name = "Users") public class Student implements IUser { @Id @Column(name = "id") private int id; @Column(name = "name") private String name; @Column(name = "password") private String password; @OneToOne(fetch = FetchType.EAGER, mappedBy = "student") private Points points; @Column(name = "type") private int type = getType(); //gets and sets... @Entity @Table(name = "Points") public class Points { @GenericGenerator(name = "generator", strategy = "foreign", parameters = @Parameter(name = "property", value = "student")) @Id @GeneratedValue(generator = "generator") @Column(name = "id", unique = true, nullable = false) private int Id; @OneToOne @PrimaryKeyJoinColumn private Student student; //gets and sets And then i do: Student student = new Student(); student.setId(1); student.setName("Andrew"); student.setPassword("Password"); Points points = new Points(); points.setPoints(0.99); student.setPoints(points); points.setStudent(student); Session session = HibernateUtil.getSessionFactory().getCurrentSession(); session.beginTransaction(); session.save(student); session.getTransaction().commit(); And hibernate saves student in the table but not saves corresponding points. Is it OK? Should i save points separately?

  • Automate open dialog box

    - by Andrey M.
    Is there any way to automate a opening files with open dialog box on Mac OS? The application asks user to open files with the standard open dialog box. But I need open files automatically. The idea is to write script or a small application which will click the button in the target application to open dialog box and then somehow select files which I needed. But I don't know how can I do it. Any suggestions will be very appreciated.

  • Using of Templated Helpers in MVC 2.0 : How can use the name of the property that I'm rendering insi

    - by Andrey Tagaew
    Hi. I'm reviewing new features of ASP.NET MVC 2.0. During the review i found really interesting using Templated Helpers. As they described it, the primary reason of using them is to provide common way of how some datatypes should be rendered. Now i want to use this way in my project for DateTime datatype My project was written for the MVC 1.0 so generating of editbox is looking like this: <%= Html.TextBox("BirthDate", Model.BirthDate, new { maxlength = 10, size = 10, @class = "BirthDate-date" })%> <script type="text/javascript"> $(document).ready(function() { $(".BirthDate-date").datepicker({ showOn: 'button', buttonImage: '<%=Url.Content("~/images/i_calendar.gif") %>', buttonImageOnly: true }); }); </script> Now i want to use Template Helper, so i want to have above code once i type next sentence: <%=Html.EditorFor(f=>f.BirthDate) %> According to the manual I create DataTime.ascx partial view inside Shared/EditorTemplates folder. I put there above code and stacked with the problem. How can i pass the name of the property that I'm rendering with template helper? As you can see from my example, i really need it, since I'm using the name of the property to specify data value and parameter name that will be send during the POST requsest. Also, I'm using it to generate class name for JS calendar building. I tried to remove my partial class for template helper and made MVC to generate its default behavior. Here what it generated for me: <input type="text" value="04/29/2010" name="LoanApplicationDays" id="LoanApplicationDays" class="text-box single-line"> As you can see, it used the name of the property for "name" and "id" attributes. This example let me to presume that Template Helper knows about the name of the property. So, there should be some way of how to use it in custom implementation. Thanks for your help!

  • Using ObservableCollection in ASP.NET

    - by Andrey
    I need to use functionality that ObservableCollection provides, in my asp.net app. My only concern is that this class is a part of WindowsBase assembly and I'm not sure if it's a good idea to include a windows assembly in a web project. Any ideas/comments? Thanks!

  • Does SQLite handle non-English locales out of the box?

    - by Andrey Tarantsov
    I have noticed that Google Toolbox for Mac replaces several SQLite built-in functions (LOWER/UPPER, LIKE, GLOB) with its own versions that handle string locales better. So, question to everyone who has SQLite experience: have you ever had any problems with non-English locales in SQLite? Does one really have to do something to properly handle non-English alphabets? What kinds of problems are expected if I use SQLite APIs as-is? (I'm going to use SQLite on the iPhone, but I guess it's the same across all platforms. I've been using Core Data previously and never had any problems, but this time I want to switch to non-ORMed db access.)

  • Writing a blocking wrapper around twisted's IRC client

    - by Andrey Fedorov
    I'm trying to write a dead-simple interface for an IRC library, like so: import simpleirc connection = simpleirc.Connect('irc.freenode.net', 6667) channel = connection.join('foo') find_command = re.compile(r'google ([a-z]+)').findall for msg in channel: for t in find_command(msg): channel.say("http://google.com/search?q=%s" % t) Working from their example, I'm running into trouble (code is a bit lengthy, so I pasted it here). Since the call to channel.__next__ needs to be returned when the callback <IRCClient instance>.privmsg is called, there doesn't seem to be a clean option. Using exceptions or threads seems like the wrong thing here, is there a simpler (blocking?) way of using twisted that would make this possible?

  • NHibernate: inserting additional calculated column

    - by Andrey Shchekin
    What would be your approach with NHibernate to do the following: When Comment is inserted into DB, and its property Text is inserted into column Text (due to a mapping), insert into column TextHash a hash of this property value. It seems trivial if I map TextHash, but how should I do this without mapping it? I do not need it in the domain model, its a DB-level optimization (I would use computed HashBytes if not for the length limit).

  • Code editor with autocomplete

    - by Andrey
    I need to create a code editor for my own simple language: className.MethodName(parameterName = 2, ... ) I've created the appropriate grammar and autogenerate parser using ANTLR tool. Now I would like to have an autocomplete for class, method, variables and parameter names. This list should be context dependent, f.e. for "class." it should display methods and for "class.Method(" - parameters. I was going to parse the text and display the list depending on in which node the cursor is. The problem is that for incomplete code like "aaa.bbb(" the parser produces an error instead of a syntax tree. Any idea how to solve this problem? Maybe I'm on the wrong way and I shouldn't parse code to display autocomplete?

  • What is a data structure for quickly finding non-empty intersections of a list of sets?

    - by Andrey Fedorov
    I have a set of N items, which are sets of integers, let's assume it's ordered and call it I[1..N]. Given a candidate set, I need to find the subset of I which have non-empty intersections with the candidate. So, for example, if: I = [{1,2}, {2,3}, {4,5}] I'm looking to define valid_items(items, candidate), such that: valid_items(I, {1}) == {1} valid_items(I, {2}) == {1, 2} valid_items(I, {3,4}) == {2, 3} I'm trying to optimize for one given set I and a variable candidate sets. Currently I am doing this by caching items_containing[n] = {the sets which contain n}. In the above example, that would be: items_containing = [{}, {1}, {1,2}, {2}, {3}, {3}] That is, 0 is contained in no items, 1 is contained in item 1, 2 is contained in itmes 1 and 2, 2 is contained in item 2, 3 is contained in item 2, and 4 and 5 are contained in item 3. That way, I can define valid_items(I, candidate) = union(items_containing[n] for n in candidate). Is there any more efficient data structure (of a reasonable size) for caching the result of this union? The obvious example of space 2^N is not acceptable, but N or N*log(N) would be.

  • Html.DropDownListFor() in Mozilla Firefox

    - by Andrey
    I'm rendering a drop down list using Html.DropDownListFor() extension. The markup I get is as follows: select id="NationalityId" name="NationalityId" option value="" /option option selected="selected" value="1"Estonian /option option value="2"Russian /option option value="3"Ukranian /option option value="4"Belorussian /option option value="5"Swedish /option option value="6"Dutch /option /select As you can see, option with value==1 is selected. But in Firefox 3.6.3 it doesn't display as selected, empty string (first option - value == "") is displayed instead. IE7 and Chrome render the page right - the option is selected. Does anybody know what is going on? How do I get this around?

  • MVVM (ICommand) in Silverlight

    - by Andrey Khataev
    Hello! Please, don't judge strictly if this question was discussed previously or indirectly answered in huge nearby prism and mvvm blogs. In WPF implementation of RelayCommand or DelegateCommand classes there is a such eventhandler /// <summary> /// Occurs whenever the state of the application changes such that the result of a call to <see cref="CanExecute"/> may return a different value. /// </summary> public event EventHandler CanExecuteChanged { add { CommandManager.RequerySuggested += value; } remove { CommandManager.RequerySuggested -= value; } } but in SL subset of namespaces there are no CommandManager class. And this is where I'm stuck. I haven't yet found an workaround for this in MVVM adoptation for SL (PRISM is so complex for me yet). Different simple HelloWorldMVVM apps don't deal with at all. Thanks in advance and sorry for my English -)

  • Multiblog engine for asp.net

    - by Andrey
    I know, different forms of this questions were asked on this site multiple times, but I haven't seen a single answer that would satisfy my need. I need a ASP.NET based blogging engine that wouul use SQL Server as a back end and allow multiple independet blogs in one app instance. I'm writing a community website for major bank and blogging is the piece I'm not sure about. Answers to other questions include a broad spectrum from BlogEngine.NET (doesn't support multiple blogs) to CommunityServer (a beast! blogging is just asmall piece of it). I don't want to install a full-blown CRM and just use blogging, I want a blogging engine. I don't mind to buy a commercial one but I can't find one. I'm pretty much stuck, and any ideas are highly appreciated!

  • What is the best practice for mvc2 confirm password field?

    - by Andrey
    I have asked a similar question recently but getting no answers i am taking a step back with a more broad approach. I am looking to create a confirm password field using asp.net MVC2 that works on the client. All my other client validation is done with MicrosoftMvcValidation.js by just adding the Html.EnableClientValidation(); call. Some of my considerations. Should the confirm password be part of the model object? Using that approach i have created server side validation by creating my own model binder. Are there any projects out there that have done this?

  • Dropdown sorting in django-admin

    - by Andrey
    I'd like to know how can I sort values in the Django admin dropdowns. For example, I have a model called Article with a foreign key pointing to the Users model, smth like: class Article(models.Model): title = models.CharField(_('Title'), max_length=200) slug = models.SlugField(_('Slug'), unique_for_date='publish') author = models.ForeignKey(User) body = models.TextField(_('Body')) status = models.IntegerField(_('Status')) categories = models.ManyToManyField(Category, blank=True) publish = models.DateTimeField(_('Publish date')) I edit this model in django admin: class ArticleAdmin(admin.ModelAdmin): list_display = ('title', 'publish', 'status') list_filter = ('publish', 'categories', 'status') search_fields = ('title', 'body') prepopulated_fields = {'slug': ('title',)} admin.site.register(Article, ArticleAdmin) and of course it makes the nice user select dropdown for me, but it's not sorted and it takes a lot of time to find a user by username.

  • Reducing a set of non-unique elements via transformations

    - by Andrey Fedorov
    I have: 1) a "starting set" of not-necessarily-unique elements, e.x. { x, y, z, z }, 2) a set of transformations, e.x. (x,z) = y, (z,z) = z, x = z, y = x, and 3) a "target set" that I am trying to get by applying transformations to the starting set, e.x. { z }. I'd like to find an algorithm to generate the (possibly infinite) possible applications of the transformations to the starting set that result in the target set. For example: { x, y, z, z }, y => x { x, x, z, z }, x => z { z, x, z, z }, x => z { z, z, z, z }, (z, z) => z { z, z, z }, (z, z) => z { z, z }, (z, z) => z { z } This sounds like something that's probably an existing (named) problem, but I don't recognize it. Can anyone help me track it down, or suggest further reading on something similar?
