  • How would this code be refactored to use jQuery?

    - by C.W.Holeman II
    How would this code be refactored to use jQuery? var lu = function luf(aPrefix){ switch (aPrefix){ case 'xhtml': return 'http://www.w3.org/1999/xhtml'; case 'math': return 'http://www.w3.org/1998/Math/MathML'; case 'svg': return 'http://www.w3.org/2000/svg'; case 'emleo': return 'http://emle.sf.net/emle020000/emleo'; } return ''; }; function emleProcessOnLoad(aThis) { var result = document.evaluate("//xhtml:span[@class='emleOnLoad']", aThis.document, lu, XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE, null); for (var jj=0; jj<result.snapshotLength; jj++){ var emleOnLoad = result.snapshotItem(jj).textContent; eval("var emleThis=result.snapshotItem(jj);" + emleOnLoad); } }

  • linq Except and custom IEqualityComparer

    - by Joe
    I'm trying to implement a custom comparer on two lists of strings and use the .Except() linq method to get those that aren't one one of the lists. The reason I'm doing a custom comparer is because I need to do a "fuzzy" compare, i.e. one string on one list could be embedded inside a string on the other list. I've made the following comparer ` public class ItemFuzzyMatchComparer : IEqualityComparer { bool IEqualityComparer<string>.Equals(string x, string y) { return (x.Contains(y) || y.Contains(x)); } int IEqualityComparer<string>.GetHashCode(string obj) { if (Object.ReferenceEquals(obj, null)) return 0; return obj.GetHashCode(); } } ` When I debug, the only breakpoint that hits is in the GetHashCode() method. The Equals() never gets touched. Any ideas?

  • jQuery Toggle with Cookie

    - by Cameron
    I have the following toggle system, but I want it to remember what was open/closed using the jQuery cookie plugin. So for example if I open a toggle and then navigate away from the page, when I come back it should be still open. This is code I have so far, but it's becoming rather confusing, some help would be much appreciated thanks. jQuery.cookie = function (name, value, options) { if (typeof value != 'undefined') { options = options || {}; if (value === null) { value = ''; options = $.extend({}, options); options.expires = -1; } var expires = ''; if (options.expires && (typeof options.expires == 'number' || options.expires.toUTCString)) { var date; if (typeof options.expires == 'number') { date = new Date(); date.setTime(date.getTime() + (options.expires * 24 * 60 * 60 * 1000)); } else { date = options.expires; } expires = '; expires=' + date.toUTCString(); } var path = options.path ? '; path=' + (options.path) : ''; var domain = options.domain ? '; domain=' + (options.domain) : ''; var secure = options.secure ? '; secure' : ''; document.cookie = [name, '=', encodeURIComponent(value), expires, path, domain, secure].join(''); } else { var cookieValue = null; if (document.cookie && document.cookie != '') { var cookies = document.cookie.split(';'); for (var i = 0; i < cookies.length; i++) { var cookie = jQuery.trim(cookies[i]); if (cookie.substring(0, name.length + 1) == (name + '=')) { cookieValue = decodeURIComponent(cookie.substring(name.length + 1)); break; } } } return cookieValue; } }; // var showTop = $.cookie('showTop'); if ($.cookie('showTop') == 'collapsed') { $(".toggle_container").hide(); $(".trigger").toggle(function () { $(this).addClass("active"); }, function () { $(this).removeClass("active"); }); $(".trigger").click(function () { $(this).next(".toggle_container").slideToggle("slow,"); }); } else { $(".toggle_container").show(); $(".trigger").toggle(function () { $(this).addClass("active"); }, function () { $(this).removeClass("active"); }); $(".trigger").click(function () { $(this).next(".toggle_container").slideToggle("slow,"); }); }; $(".trigger").click(function () { if ($(".toggle_container").is(":hidden")) { $(this).next(".toggle_container").slideToggle("slow,"); $.cookie('showTop', 'expanded'); } else { $(this).next(".toggle_container").slideToggle("slow,"); $.cookie('showTop', 'collapsed'); } return false; }); and this is a snippet of the HTML it works with: <li> <label for="small"><input type="checkbox" id="small" /> Small</label> <a class="trigger" href="#">Toggle</a> <div class="toggle_container"> <p class="funding"><strong>Funding</strong></p> <ul class="childs"> <li class="child"> <label for="fully-funded1"><input type="checkbox" id="fully-funded1" /> Fully Funded</label> <a class="trigger" href="#">Toggle</a> <div class="toggle_container"> <p class="days"><strong>Days</strong></p> <ul class="days clearfix"> <li><label for="1pre16">Pre 16</label> <input type="text" id="1pre16" /></li> <li><label for="2post16">Post 16</label> <input type="text" id="2post16" /></li> <li><label for="3teacher">Teacher</label> <input type="text" id="3teacher" /></li> </ul> </div> </li>

    Hello. I am using a ComboBox bound under a DataContext: <tk:DataGridTemplateColumn.CellEditingTemplate> <DataTemplate> <ComboBox ItemsSource="{Binding Source={StaticResource CategoriesCollection}" DisplayMemberPath="Title" SelectedItem="{Binding Category}" /> </DataTemplate> </tk:DataGridTemplateColumn.CellEditingTemplate> When the row is initiated the value of Category is null.

  • SQLConnection.Open(); throwing exception

    - by flavour404
    Hi, Updating an old piece of software but in order to maintain backward compatibility I need to connect to a .mdb (access) database.

  • How to save http referer in rails

    - by TenJack
    I'm trying to save the site that a user came from when they sign up. Right now I have a before_filter in my ApplicationController: before_filter :save_referer def save_referer unless is_logged_in? session['referer'] = request.env["HTTP_REFERER"] unless session['referer'] end end Then when a user is created, it checks this session variable and sets it to nil. Sometimes this does not work and I'm worried there might be some unintended things happening with using session like this. Does anyone have a better way? Or some input perhaps? EDIT: This is the logic I am using to save the referer: def create @user = User.new(params[:user]) if @user.save_with(session[:referer]) .... end User def save_with(referer) self.referer = referer unless referer == "null" self.save end Is there any reason why this should not work?

  • Embedding Ruby, calling a function from C

    - by ThePower
    Hi, I'm writing an app that calls ruby code from c. I am having a little difficulty and wondered if anyone could point me in the rite direction. I currently have in my C. #include ruby.h main() { ruby_init(); rb_require("myRubyFile"); rb_funcall(rb_module_new(), rb_intern("RubyFunction"), 0, NULL); } My ruby file is in the same directory as my c file and is called myRubyFile.rb and contains a definition of the function RubyFunction(). This is a cut down of what I actually want to do, just making it more readable for others. I just require some feedback as to whether this is the correct method to call ruby code from my c file.

  • Force jQuery to accept XHTML string as XML?

    - by MidnightLightning
    So, as part of a baseline OpenID implementation in Javascript, I'm fetching a remote page source through AJAX, and looking for the <link rel="openid.server" href="http://www.example.com" /> tag in the head. I'm using the jQuery javascript library for the AJAX request, but am unable to parse out the link tags. Several other online sources talk about using the usual jQuery selectors to grab tags from XML/XHTML sources, but it seems jQuery can only get content from the body of an HTML document, not the head (which is where the link tags are; $(response).find('link') returns null). So, I'd either need to get jQuery to force this document into XML mode or otherwise get at the head tags. Is there a way to force jQuery to parse the response of an AJAX query as XML, when it's in reality XHTML? Or do I need to fall back to regular expressions to get the link tags out?

  • How does Linq-to-Xml convert objects to strings?

    - by Eamon Nerbonne
    Linq-to-Xml contains lots of methods that allow you to add arbitrary objects to an xml tree. These objects are converted to strings by some means, but I can't seem to find the specification of how this occurs. The conversion I'm referring to is mentioned (but not specified) in MSDN. I happen to need this for javascript interop, but that doesn't much matter to the question. Linq to Xml isn't just calling .ToString(). Firstly, it'll accept null elements, and secondly, it's doing things no .ToString() implementation does: For example: new XElement("elem",true).ToString() == "<elem>true</elem>" //but... true.ToString() == "True" //IIRC, this is culture invariant, but in any case... true.ToString(CultureInfo.InvariantCulture) == "True" Other basic data types are similarly specially treated. So, does anybody know what it's doing and where that's described?

  • nHibernate Criteria API Projections

    - by Craig
    I have an entity that is like this public class Customer { public Customer() { Addresses = new List<Address>(); } public int CustomerId { get; set; } public string Name { get; set; } public IList<Address> Addresses { get; set; } } And I am trying to query it using the Criteria API like this. ICriteria query = m_CustomerRepository.Query() .CreateAlias("Address", "a", NHibernate.SqlCommand.JoinType.LeftOuterJoin); var result = query .SetProjection(Projections.Distinct( Projections.ProjectionList() .Add(Projections.Alias(Projections.Property("CustomerId"), "CustomerId")) .Add(Projections.Alias(Projections.Property("Name"), "Name")) .Add(Projections.Alias(Projections.Property("Addresses"), "Addresses")) )) .SetResultTransformer(new AliasToBeanResultTransformer(typeof(Customer))) .List<Customer>() as List<Customer>; When I run this query the Addresses property of the Customer object is null. Is there anyway to add a projection for this List property?

  • Generic type parameters using out

    - by Mikael
    Im trying to make a universal parser using generic type parameters, but i can't grasp the concept 100% private bool TryParse<T>(XElement element, string attributeName, out T value) where T : struct { if (element.Attribute(attributeName) != null && !string.IsNullOrEmpty(element.Attribute(attributeName).Value)) { string valueString = element.Attribute(attributeName).Value; if (typeof(T) == typeof(int)) { int valueInt; if (int.TryParse(valueString, out valueInt)) { value = valueInt; return true; } } else if (typeof(T) == typeof(bool)) { bool valueBool; if (bool.TryParse(valueString, out valueBool)) { value = valueBool; return true; } } else { value = valueString; return true; } } return false; } As you might guess, the code doesn't compile, since i can't convert int|bool|string to T (eg. value = valueInt). Thankful for feedback, it might not even be possible to way i'm doing it. Using .NET 3.5

  • Global WH_CBT hook DLL is loaded into some processes only

    - by kriau
    The main program calls the function SetHook in the wi.dll to install global WH_CBT hook. bool WI_API SetHook() { if (!g_hHook) { g_hHook = SetWindowsHookEx(WH_CBT, (HOOKPROC) CBTProc, g_hInstDll, 0); } return g_hHook != NULL; } I presume after installing global hook, wi.dll should be loaded into each process' address space. However wi.dll is loaded in to some processes only. For example, if I start Skype, MS Word I can see that wi.dll is loaded into these processes as well (using Process Explorer), however if I run Firefox, uTorrent, Adobe Reader then wi.dll is not loaded into these processes. I'm using W7 64-bit, main program and wi.dll is 32-bit, all programs mentioned here is 32-bit programs as well. Any ideas why that happens? Thanks in advance.

  • Databinding race condition

    - by Stephen Price
    I have a login form (using ChildWindow) and have implemented a Keyup event handler on the passwordbox. If the key is enter then it sets the ChildWindow ResultDialog to true. What seems to be happening is the databinding on the Passwordbox is not happening before the childwindow is closed so the Password property on my Login control is null. I've tried using KeyUp and Keydown, as well as using a buttonAutoPeer to invoke a click on the Ok button. I've also tried setting the focus to the OKbutton before setting the DialogResult (which closes the window). private void PasswordBox_KeyUp(object sender, KeyEventArgs e) { if (e.Key == Key.Enter) { if (UsernameBox.Text != userPrompt && !string.IsNullOrEmpty(PasswordBox.Password.Trim())) { this.DialogResult = true; } else { UsernameBox.Focus(); } } }

  • ASP.NET MVC Route Contraints with {ID}-{Slug} Format

    - by TimLeung
    I have a route like following, ideally I would like it to match: domain.com/layout/1-slug-is-the-name-of-the-page routes.MapRoute( "Layout", // Route name "layout/{id}-{slug}", // URL with parameters new { controller = "Home", action = "Index", id = @"\d+$" } ); But when I hit the url, I am keep on getting this exception: The parameters dictionary contains a null entry for parameter 'id' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.ActionResult Index(Int32)' in .... The above route will match the following though: domain.com/layout/1-slug or domain.com/layout/1-slug_permalink Seems like the hyphen that separates the ID from the Slug is causing issues.

  • Webreference vs servicereference. Why ony one works ?

    - by phenevo
    Hi, I've got two applications. One uses webreference to my webservice, and second use servicereference to my webservice. There is metohod which I'm invoking: [WebMethod] public Car[] GetCars(string carCode) { Cars[] cars= ModelToContract.ToCars(MyFacade.GetCars(carCode); return cars; } Car has two pools: string Code {get;set;} CarType Type {get;set;} public enum CarType { Van=0, Pickup=1 } I'm debuging this webMethod, and... at the end webservice throw good collection of cars, which has one car: code="bmw",Type.Van But... Application with webrefence receives the same collection and application with servicereference gets collection, where field code is null... Invoking servicereference: MyService myService=new MyService() Cars[] cars= client.GetCars(carcode); Invoking webservice: MyService.MyServiceSoapClient client = new MyServiceS.MyServiceSoapClient(); Cars[] cars= client.GetCars(carcode);

  • System.Net.WebProxy in .NET Client

    - by NealWalters
    I don't yet have a good understanding of how the network is set up at my current client, but here is my issue. The vendor has a normal URL, but it might be a leased line. I have a .NET program that calls an external .asmx service. If I go to IE, Connections, LAN Settings, and uncheck "Automatic detect settings" and uncheck "Use Automatic Configuration Sript", then the .NET program runs and access the web service fine. But then, to access internet again from the browser, I have to re-check the two boxes, and so on throughout the day while we are testing and browsing. I'm hoping to put some code like this in the .NET program to avoid us having to constantly change: if (chkUseProxy.Checked) { myclient.Proxy = new System.Net.WebProxy(""); } I tried null and empty string and so far not able to connect without errors. Is this possible, and if so, what might be the correct parms for the constructor? Or are there other objects or properties that would need to be set? Thanks, Neal Walters
