  • Get dragged / saved items state back from Sql Server

    - by user571507
    Ok i saw many post's on how to serialize the value of dragged items to get hash and they tell how to save them. Now the question is how do i persist the dragged items the next time when user log's in using the has value that i got eg: <ul class="list"> <li id="id_1"> <div class="item ui-corner-all ui-widget ui-widget-content"> </div> </li> <li id="id_2"> <div class="item ui-corner-all ui-widget ui-widget-content"> </div> </li> <li id="id_3"> <div class="item ui-corner-all ui-widget ui-widget-content"> </div> </li> <li id="id_4"> <div class="item ui-corner-all ui-widget"> </div> </li> </ul> which on serialize will give "id[]=1&id[]=2&id[]=3&id[]=4" Now think that i saved it to Sql server database in a single field called SortOrder. Now how do i get the items to these order again ? the code to make these sort is below,without which people didn't know which library i had used to sort and serialize <script type="text/javascript"> $(document).ready(function() { $(".list li").css("cursor", "move"); $(".list").sortable(); }); </script>

  • ASP.Net MVC 2 is it possible to get the same instance of model(with slight changes) in HttpPost meth

    - by jjjjj
    Hi I have a complex entity User: public class User : BaseEntity { public virtual Taxi Taxi { get; set; } --> That is why i call it "complex" public virtual string Login { get; set; } public virtual string Password { get; set; } } where Taxi is a parent of User (Taxi has-many Users): public class Taxi : BaseEntity { public virtual string Name { get; set; } public virtual string ClientIp { get; set; } } BaseEntity consists of public virtual int Id { get; private set; } The problem occurs while trying to edit User [Authorize] public ActionResult ChangeAccountInfo() { var user = UserRepository.GetUser(User.Identity.Name); return View(user); } My ChangeAccountInfo.aspx <fieldset> <legend>Fields</legend> <% %> <div class="editor-label"> <%: Html.LabelFor(model => model.Login) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.Login) %> <%: Html.ValidationMessageFor(model => model.Login) %> </div> <div class="editor-label"> <%: Html.LabelFor(model => model.Password) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.Password) %> <%: Html.ValidationMessageFor(model => model.Password) %> </div> <div class="editor-field"> <%: Html.HiddenFor(model => model.Taxi.Name)%> </div> <p> <input type="submit" value="Save" /> </p> </fieldset> Post changes: [Authorize] [HttpPost] public ActionResult ChangeAccountInfo(User model) { if (ModelState.IsValid) { UserRepository.UpdateUser(model); return RedirectToAction("ChangeAccountInfoSuccess", "Account"); } return View(model); } But, the (User model) parameter has User.Id == 0 -- User entity had 5 before edit User.Login == "my new login" User.Password == "my new password" User.Taxi.Id == 0 -- User.Taxi entity had 3 before edit User.Taxi.Name == "old hidden name" User.Taxi.ClientIp == null -- User entity had 192.168.0.1 before edit Q: Is it possible not to mark all the fields of an entity (that should be in my UpdateUser) with tag "hidden" but still have them unchanged in my HttpPost method? e.g. not User.Taxi.ClientIp = null, but User.Taxi.ClientIp = 192.168.0.1 I'm using nhibernate, if it matters.

  • Does C++ have a static polymorphism implementation of interface that does not use vtable?

    - by gilbertc
    Does C++ have a proper implementation of interface that does not use vtable? for example class BaseInterface{ public: virtual void func() const = 0; } class BaseInterfaceImpl:public BaseInterface{ public: void func(){ std::cout<<"called."<<endl; } } BaseInterface* obj = new BaseInterfaceImpl(); obj->func(); the call to func at the last line goes to vtable to find the func ptr of BaseInterfaceImpl::func, but is there any C++ way to do that directly as the BaseInterfaceImpl is not subclassed from any other class besides the pure interface class BaseInterface? Thanks. Gil.

  • Why jquery have problem with onbeforeprint event?

    - by Cesar Lopez
    Hi all, I have the following function. $(function() { $(".sectionHeader:gt(0)").click(function() { $(this).next(".fieldset").slideToggle("fast"); }); $("img[alt='minimize']").click(function(e) { $(this).closest("table").next(".fieldset").slideUp("fast"); e.stopPropagation(); return false; }); $("img[alt='maximize']").click(function(e) { $(this).closest("table").next(".fieldset").slideDown("fast"); e.stopPropagation(); return false; }); }); <script type="text/javascript"> window.onbeforeprint = expandAll; function expandAll(){ $(".fieldset:gt(0)").slideDown("fast"); } </script> For this html <table class="sectionHeader" ><tr ><td>Heading 1</td></tr></table> <div style="display:none;" class="fieldset">Content 1</div> <table class="sectionHeader" ><tr ><td>Heading 2</td></tr></table> <div style="display:none;" class="fieldset">Content 2</div> I have several div class="fieldset" over the page, but when I do print preview or print, I can see all divs sliding down before opening the print preview or printing but on the actual print preview or print out they are all collapse. I would appreciate if anyone comes with a solution for this. Anyone have any idea why is this or how to fix it? Thanks. PS:Using a does not work either ( I assume because jquery using toggle) and its not the kind of question I am looking for.

    need help on passing data from an activity to an listactivity or listview for an android app. im having problems on passing data to a listview. what the app do is from addact class the user can input things to do and in the viewact class this will display the activies add by the user in listview public class addact extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.newact); Button btn1 = (Button)findViewById(R.id.btnsave); final EditText et1 = (EditText)findViewById(R.id.etactivity); btn1.setOnClickListener(new OnClickListener() { @Override public void onClick(View arg0) { Intent it = new Intent(addact.this, viewact.class); it.putExtra("thekey", et1.getText().toString()); startActivity(it); } }); } } public class viewact extends ListActivity { String addToDo =getIntent().getExtras().getString("thekey"); String[] toDoAct = new String[] {addToDo }; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.viewact); setListAdapter(new ArrayAdapter<String>(this, R.layout.viewact,toDoAct)); ListView listView = getListView(); listView.setTextFilterEnabled(true); listView.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> parent, View view, int position, long id) { for (int i=0; i < 2; i++) { Toast.makeText(getApplicationContext(), ((TextView) view).getText(), Toast.LENGTH_LONG).show(); } } }); } }

  • How to call a generic method with an anonymous type involving generics?

    - by Alex Black
    I've got this code that works: def testTypeSpecialization = { class Foo[T] def add[T](obj: Foo[T]): Foo[T] = obj def addInt[X <% Foo[Int]](obj: X): X = { add(obj) obj } val foo = addInt(new Foo[Int] { def someMethod: String = "Hello world" }) assert(true) } But, I'd like to write it like this: def testTypeSpecialization = { class Foo[T] def add[X, T <% Foo[X](obj: T): T = obj val foo = add(new Foo[Int] { def someMethod: String = "Hello world" }) assert(true) } This second one fails to compile: no implicit argument matching parameter type (Foo[Int]{ ... }) = Foo[Nothing] was found. Basically: I'd like to create a new anonymous class/instance on the fly (e.g. new Foo[Int] { ... } ), and pass it into an "add" method which will add it to a list, and then return it The key thing here is that the variable from "val foo = " I'd like its type to be the anonymous class, not Foo[Int], since it adds methods (someMethod in this example) Any ideas? I think the 2nd one fails because the type Int is being erased. I can apparently 'hint' the compiler like this: def testTypeSpecialization = { class Foo[T] def add[X, T <% Foo[X]](dummy: X, obj: T): T = obj val foo = add(2, new Foo[Int] { def someMethod: String = "Hello world" }) assert(true) }

  • Hibernate NamingStrategy implementation that maintains state between calls

    - by Robert Petermeier
    Hi, I'm working on a project where we use Hibernate and JBoss 5.1. We need our entity classes to be mapped to Oracle tables that follow a certain naming convention. I'd like to avoid having to specify each table and column name in annotations. Therefore, I'm currently considering implementing a custom implementation of org.hibernate.cfg.NamingStrategy. The SQL naming conventions require the name of columns to have a suffix that is equivalent to a prefix of the table name. If there is a table "T100_RESOURCE", the ID column would have to be named "RES_ID_T100". In order to implement this in a NamingStrategy, the implementation would have to maintain state, i.e. the current class name it is creating the mappings for. It would rely on Hibernate to always call classToTableName() before propertyToColumnName() and to determine all column names by calling propertyToColumnName() before the next call to classToTableName() Is it safe to do that or are there situations where Hibernate will mix things up? I am not thinking of problems through multiple threads here (which can be solved by keeping the last class name in a ThreadLocal) but also of Hibernate deliberately calling this out of order in certain circumstances. For example Hibernate asking for mappings of three properties of class A, then one of class B, then again more attributes of class A.

  • Implementing hoverIntent for Drop Down Menu (coming from click_event)

    - by stormeTrooper
    I've just recently started programming, I was hoping for some help. I have a drop down menu that was originally activated by click_event, however I want to now implement hoverIntent in order to make the menu drop. The issue I am having now is being able to use the menu, because whenever I invoke the menu now, once I leave the area that activates the menu, the menu closes. If you could explain to me like I'm five, I'd appreciate it, thanks :) The code I am using as follows: JavaScript: function setupUserConfigMenu() { $('.user_profile_btn').hoverIntent( function (event) { $('#user_settings_dropdown').animate({height:['toggle', 'swing'] }, 225); }, function (event) { $('#user_settings_dropdown').animate({height:['toggle', 'swing'] }, 225); }) } HTML: <li> <a href="<%= "#" %>" class="user_profile_btn" title="Your profile page"><%= truncate(current_user.full_name || current_user.name, :length => 28) %> <div class="arrow_down"></div></a> <ul id="user_settings_dropdown"> <li> <a href="<%= current_user.get_url(true) %>"> <%= image_tag current_user.get_thumb_url, :size => "30x30" %> <div> <%= truncate(current_user.full_name || current_user.name, :length => 40) %> <br> View profile </div> </a> </li> <div class="grey_line"></div> <li class="settings_list_item"> <%= link_to "Settings", edit_user_registration_path %> </li> <li class="settings_list_item"> <%= link_to "About", "/about" %> </li> <li class="settings_list_item"> <%= link_to "Logout", destroy_user_session_path, :method => :delete %> </li> </ul> </li>

  • Issue selenium code maintenance

    I want to group the common methods in one file and use it. For example, login to a page using selenium may be used in multiple times. Define that in class A and call it in class B. However, it throws null pointer exception. class A has public void test_Login() throws Exception { try{ selenium.setTimeout("60000"); selenium.open("http://localhost"); selenium.windowFocus(); selenium.windowMaximize(); selenium.windowFocus(); selenium.type("userName", "admin"); selenium.type("password", "admin"); Result=selenium.isElementPresent("//input[@type='image']"); selenium.click("//input[@type='image']"); selenium.waitForPageToLoad(Timeout); } catch(Exception ex) { System.out.println(ex); ex.printStackTrace(); } } with all other java syntax in class B public void test_kk() throws Exception { try { a.test_Login(); } catch(Exception ex) { System.out.println(ex); ex.printStackTrace(); } } with all syntax.

  • C++ constant reference lifetime

    - by aaa
    hello I have code that looks like this: class T {}; class container { const T &first, T &second; container(const T&first, const T & second); }; class adapter : T {}; container(adapter(), adapter()); I thought lifetime of constant reference would be lifetime of container. However, it appears otherwise, adapter object is destroyed after container is created, leading dangling reference. What is the correct lifetime? how to correctly implement binding temporary object to class member reference? Thanks

  • NHibernate + Cannot insert the value NULL into...

    - by mybrokengnome
    I've got a MS-SQL database with a table created with this code CREATE TABLE [dbo].[portfoliomanager]( [idPortfolioManager] [int] NOT NULL PRIMARY KEY IDENTITY, [name] [varchar](45) NULL ) so that idPortfolioManager is my primary key and also auto-incrementing. Now on my Windows WPF application I'm using NHibernate to help with adding/updating/removing/etc. data from the database. Here is the class that should be connecting to the portfoliomanager table namespace PortfolioManager { [Class(Table="portfoliomanager",NameType=typeof(PortfolioManagerClass))] public class PortfolioManagerClass { [Id(Name = "idPortfolioManager")] [Generator(1, Class = "identity")] public virtual int idPortfolioManager { get; set; } [NHibernate.Mapping.Attributes.Property(Name = "name")] public virtual string name { get; set; } public PortfolioManagerClass() { } } } and some short code to try and insert something PortfolioManagerClass portfolio = new PortfolioManagerClass(); Portfolio.name = "Brad's Portfolios"; The problem is, when I try running this, I get this error: {System.Data.SqlClient.SqlException: Cannot insert the value NULL into column 'idPortfolioManager', table 'PortfolioManagementSystem.dbo.portfoliomanager'; column does not allow nulls. INSERT fails. The statement has been terminated... with an outer exception of {"could not insert: [PortfolioManager.PortfolioManagerClass][SQL: INSERT INTO portfoliomanager (name) VALUES (?); select SCOPE_IDENTITY()]"} I'm hoping this is the last error I'll have to solve with NHibernate just to get it to do something, it's been a long process. Just as a note, I've also tried setting Class="native" and unsaved-value="0" with the same error. Thanks! Edit: Ok removing the 1, from Generator actually allows the program to run (not sure why that was even in the samples I was looking at) but it actually doesn't get added to the database. I logged in to the server and ran the sql server profiler tool and I never see the connection coming through or the SQL its trying to run, but NHibernate isn't throwing an error anymore. Starting to think it would be easier to just write SQL statements myself :(

  • Silverlight Binding - Binds when item is added but doesn't get updates.

    - by dw
    Hello, I'm sorta at a loss to why this doesn't work considering I got it from working code, just added a new level of code, but here's what I have. Basically, when I bind the ViewModel to a list, the binding picks up when Items are added to a collection. However, if an update occurs to the item that is bound, it doesn't get updated. Basically, I have an ObservableCollection that contains a custom class with a string value. When that string value gets updated I need it to update the List. Right now, when I debug, the list item does get updated correctly, but the UI doesn't reflect the change. If I set the bound item to a member variable and null it out then reset it to the right collection it will work, but not desired behavior. Here is a mockup of the code, hopefully someone can tell me where I am wrong. Also, I've tried implementing INofityPropertyChanged at every level in the code below. public class Class1 { public string ItemName; } public class Class2 { private Class2 _items; private Class2() //Singleton { _items = new ObservableCollection<Class1>(); } public ObservableCollection<Class1> Items { get { return _items; } internal set { _items = value; } } } public class Class3 { private Class2 _Class2Instnace; private Class3() { _Class2Instnace = Class2.Instance; } public ObservableCollection<Class1> Items2 { get {return _Class2Instnace.Items; } } } public class MyViewModel : INofityPropertyChanged { private Class3 _myClass3; private MyViewModel() { _myClass3 = new Class3(); } private BindingItems { get { return _myClass3.Items2; } // Binds when adding items but not when a Class1.ItemName gets updated. } }

  • jQuery validate plugin radio with optional text

    - by timborden
    I'm trying to figure out how to validate a form element with a mix of radio inputs and a text input: <label>Question?</label> <input type="radio" class="mandatory" name="questions[1][]" value="1" />answer 1<br/> <input type="radio" class="mandatory" name="questions[1][]" value="2" />answer 2<br/> <input class="ignore" type="radio" id="questions[1][]" />Other (please specify)<br/> <input class="optional mandatory" type="text" name="questions[1][]" value="" /> I've figured out how to get the form to behave as expected (select and unselect) with the following code: $("input.optional").focus(function () { var this_name = $(this).attr("name"); $("input:radio").filter(function() {return $(this).attr('name') == this_name; }).attr('checked', false); $("input").filter(function() {return $(this).attr('id') == this_name; }).attr('checked', true); }); $(':radio').click(function () { var this_name = $(this).attr("name"); $("input").filter(function() {return $(this).attr('id') == this_name; }).attr('checked', false); $("input.optional").filter(function() {return $(this).attr('name') == this_name; }).val(''); }); I was hoping I could use the class "mandatory" to validate the mix of radio and text inputs: $("form .manditory").each(function () { $(this).rules("add", {required: true}); }); But it's not working as expected. With the radio (id="questions[1][]") selected, and the text input containing content, the form element is still flagged as invalid. Suggestions...maybe a better approach? Thanks in advance. UPDATE Sorry, I should have clarified that I'm using the validate plugin: $("form").validate({ ... });

  • jQuery - Need help stopping animation on click command.

    - by iamtheratio
    With a few of your help I was able to get the jquery I wanted to work flawlessly, except for one thing.. the animation doesn't stop when i click on the buttons. Scenario: I have an Image, and 3 buttons underneath labeled "1","2", and "3". The jquery will automate the click function every 4500ms and switch from 1 to 2, then 2 to 3 and continuously loop. However the problem is, if I manually click on a 1,2,3 button the animation does not stop. Any ideas how I could accomplish this? jQuery: var tabs; var len; var index = 1; var robot; function automate() { tabs.eq((index%len)).trigger('click'); index++; } robot = setInterval(automate, 5500); jQuery(document).ready(function(){ jQuery(".imgs").hide(); jQuery(".img_selection a").click(function(){ stringref = this.href.split('#')[1]; $(".img_selection a[id$=_on]").removeAttr('id'); this.id = this.className + "_on"; jQuery('.imgs').hide(); if (jQuery.browser.msie && jQuery.browser.version.substr(0,3) == "6.0") { jQuery('.imgs#' + stringref).show(); } else jQuery('.imgs#' + stringref).fadeIn(); return false; }); $('.img_selection a').removeAttr('id').eq(0).trigger('click'); tabs = jQuery(".img_selection a"); len = tabs.size(); }); I tried adding the below code, with a lot of help from this website, but to no avail.. CODE: jQuery(document).ready(function(){ jQuery(".imgs").hide().click(function(){ clearInterval(robot); }); HTML: <!-- TOP IMAGE ROTATION --> <div id="upper_image"> <div id="img1" class="imgs"> <p><img src="images/top_image.jpg" width="900" height="250" alt="The Ratio - Print Projects!" border="0" /></p> </div> <div id="img2" class="imgs"> <p><img src="images/top_image2.jpg" width="900" height="250" alt="The Ratio - In The Works!" border="0" /></p> </div> <div id="img3" class="imgs"> <p><img src="images/top_image3.jpg" width="900" height="250" alt="The Ratio!" border="0" /></p> </div> </div> <!-- / TOP IMAGE ROTATION --> <!-- TOP IMAGE SELECTION --> <ul class="img_selection"> <li><a id="img1_on" class="img1" href="#img1">1</a></li> <li><a class="img2" href="#img2">2</a></li> <li><a class="img3" href="#img3">3</a></li> </ul> <!-- / TOP IMAGE SELECTION -->

  • How to append() an element and set its style with css() at the same time with jQuery

    I tried: $('#canvas').append('<div class="tile"></div>').css({left: leftPos, top: topPos});, but that sets the style of #canvas rather than the appended element. I then tried: $('#canvas').append(('<div class="tile"></div>').css({left: leftPos, top: topPos}));, but that gives the error "Object <div class="tile"></div> has no method 'css'". How can I add the element and set its style at the same time?

    If I have an instance of a class that I store in a session I need to make it serializable. This class has a static variable, will this be serialized in every instance stored? The static variable is a reference to a cache containing a lot of data in the background. Will all of this data be serialized? If so, it seems preferable to make this variable transient and re-fetch the cache instance each time the instance is restored. Maybe not store the cache instance at all in the class. Will the constructor execute when a class is restored from a serialized state? if not is there any other method I can use to re-instate a transient variable?

  • NSXMLParser 's delegate and memory leak

    - by dizzy_fingers
    Hello, I am using a NSXMLParser class in my program and I assign a delegate to it. This delegate, though, gets retained by the setDelegate: method resulting to a minor, yet annoying :-), memory leak. I cannot release the delegate class after the setDelegate: because the program will crash. Here is my code: self.parserDelegate = [[ParserDelegate alloc] init]; //retainCount:1 self.xmlParser = [[NSXMLParser alloc] initWithData:self.xmlData]; [self.xmlParser setDelegate:self.parserDelegate]; //retainCount:2 [self.xmlParser parse]; [self.xmlParser release]; ParserDelegate is the delegate class. Of course if I set 'self' as the delegate, I will have no problem but I would like to know if there is a way to use a different class as delegate with no leaks. Thank you in advance.
