  • Permissions for Large Variables to Be Sent Via Stored Procedures (SQL Server)

    - by Joe Majewski
    I can't figure out a way to allow more than 4000 bytes to be received at once via a call to a stored procedure. I am storing images in the table that are around 15 - 20 kilobytes each, but upon getting them and displaying them to the page, they are always exactly 3.91 KB in size (or 4000 bytes). Do stored procedures have a limit on how much data can be sent at once? I double-checked my data, and I am indeed only receiving the first 4000 characters from the varbinary(MAX) field. Is there a permission setting to allow more than 4k bytes at once?

  • Render Order via HTML or CSS

    - by Bullines
    What is the best practice is in the case of altering the render order of elements on a webpage. For example, I have two DIVs that are to be displayed on a page: <div id="appleSection"> <!-- Apple DIVs, content, form elements, etc --> </div> <div id="orangeSection"> <!-- Orange DIVs, content, form elements, etc --> </div> Depending on user selection (perhaps by country or something), the order which the DIVs are presented to the user can differ. Certain conditions present appleSection above orangeSection, and for other conditions, their order is reversed. If the core logic of the page is the same regardless, is it a best practice to determine order on the server-side (perhaps via two pages that differ in the order of the DIVs), or is it more appropriate to have just a single page and use CSS to control whether appleSection is above orangeSection or vice versa?

  • Problem with passing folder path string to web service function via jQuery.ajax

    - by the_V
    Hello, I need to perform asp.net web-service function call via jQuery and pass asp.net application path to it. That's the way I'm trying to do it (code is located within asp.net page, e.g. aspx file): var d = "{'str':'<%=System.DateTime.Now.ToString() %>', 'applicationPath':'<%=GetApplicationPath() %>'}"; $.ajax({ type: "POST", url: "http://localhost/testwebsite/TestWebService.asmx/Test", data: d, contentType: "application/json; charset=utf-8", dataType: "json", error: function (xhr, status, error) { var err = eval("(" + xhr.responseText + ")"); alert(err.Message); }, success: function (msg) { } }); That's what GetApplicationPath method looks like: protected string GetApplicationPath() { return HttpUtility.HtmlEncode(Request.PhysicalApplicationPath); } And here is a header of web-service function which I'm trying to call: public void Test(string str, string applicationPath) Function call works well, but applicationPath parameter doesn't passed correctly. When I debug it I see that backslashes are removed, function gets "C:ProjectsSamplesmytestwebsite" instead of "'C:\Projects\Samples\mytestwebsite\'". How can I overcome this?

  • sending data to the server via port 5555 C#

    - by numerical25
    I am wanting to send some data to a server from a client application to the server via port 5555. I don't have a window's server. My question is if I purchase a .Net Framework hosting service. Would I be able to connect the client application to this server. and could I do it by sending a Post. I am new to this, so excuse me if it doesn't entire make sense. but I am looking for just some little direction. If someone could explain what port 5555 is used for that would be great.

  • Anyone plotting SO via code_swarm?

    - by Tim Post
    Is anyone working on something to render individual questions, or SO as a whole with codeswarm? If so, can you post a link to your work that transforms SO questions into revisions that codeswarm can understand (i.e. svn?) It would be really, really cool to see SO played (as a whole) via codeswarm, so I hope to not only ask if anyone is working it, but see if anyone is interested in trying to accomplish it. Augmenting that, will database dumps be made available? EDIT: Database dumps have since been made available :) Enough with user voice, is anyone doing it? If so, what VCS did you mock?

  • L2S DataContext out of synch: row not found or changed

    - by awrigley
    The Problem I am getting a number of errors that imply that the DataContext, or rather, the way I am using the DataContext is getting out of synch. The error occurs on db.SubmitChanges() where db is my DataContext instance. The error is: Row not found or changed. The problem only occurs intermitently, for example, adding a row then deleting it. If I stop the dev server and restart, the added row is there and I can delete it no problem. Ie, it seems that the problem is related to the DataContext losing track of the rows that have been added. IMPORTANT: Before anyone votes to close this thread, on the basis of it being a duplicate, I have checked the sql server profiler and there is no "Where 0 = 1" in the SQL. I have also recreated the dbml file, so am satisfied that the database schema is in synch with the schema represented by the dbml file. Ie, no cases of mismatched nullable/not nullable columns, etc. My Diagnosis (for what it is worth): It seems to be a problem related to how I am using the DataContext. I am new to MVC, Repositories and Services patterns, so suspect that I have wired things up wrong. The Setup Simple eLearning app in its early stages. Pupils need to be able to add and delete courses (Courses table) to their UserCourses. To do this, I have a service that gets a specific DataContext instance Dependency Injected into its constructor. Service Class Constructor: public class SqlPupilBlockService : IPupilBlockService { DataContext db; public SqlPupilBlockService(DataContext db) { this.db = db; CoursesRepository = new SqlRepository<Course>(db); UserCoursesRepository = new SqlRepository<UserCourse>(db); } // Etc, etc } The CoursesRepository and UserCoursesRepository are both private properties of the service class that are of Type IRepository (just a simple generic repository interface). Sql Respoitory Code: public class SqlRepository<T> : IRepository<T> where T : class { DataContext db; public SqlRepository(DataContext db) { this.db = db; } #region IRepository<T> Members public IQueryable<T> Query { get { return db.GetTable<T>(); } } public List<T> FetchAll() { return Query.ToList(); } public void Add(T entity) { db.GetTable<T>().InsertOnSubmit(entity); } public void Delete(T entity) { db.GetTable<T>().DeleteOnSubmit(entity); } public void Save() { db.SubmitChanges(); } #endregion } The two methods for adding and deleting UserCourses are: Service Methods for Adding and Deleting UserCourses: public void AddUserCourse(int courseId) { UserCourse uc = new UserCourse(); uc.IdCourse = courseId; uc.IdUser = UserId; uc.DateCreated = DateTime.Now; uc.DateAmended = DateTime.Now; uc.Role = "Pupil"; uc.CourseNotes = string.Empty; uc.ActiveStepIndex = 0; UserCoursesRepository.Add(uc); UserCoursesRepository.Save(); } public void DeleteUserCourse(int courseId) { var uc = (UserCoursesRepository.Query.Where(x => x.IdUser == UserId && x.IdCourse == courseId)).Single(); UserCoursesRepository.Delete(uc); UserCoursesRepository.Save(); } Ajax I am using Ajax via Ajax.BeginForm I don't think that is relevant. ASP.NET MVC 3 I am using mvc3, but don't think that is relevant: the errors are related to model code.

  • Serious problem with WCF, GridViews, Callbacks and ExecuteReaders exceptions.

    - by barjed
    Hi, I have this problem that is driving me insane. I have a project to deliver before Thursday. Basically an app consiting of three components that communicate with each other in WCF. I have one console app and one Windows Forms app. The console app is a server that's connected to the database. You can add records to it via the Windows Forms client that connectes with the server through the WCF. The code for the client: namespace BankAdministratorClient { [CallbackBehavior(ConcurrencyMode = ConcurrencyMode.Single, UseSynchronizationContext = false)] public partial class Form1 : Form, BankServverReference.BankServerCallback { private BankServverReference.BankServerClient server = null; private SynchronizationContext interfaceContext = null; public Form1() { InitializeComponent(); interfaceContext = SynchronizationContext.Current; server = new BankServverReference.BankServerClient(new InstanceContext(this), "TcpBinding"); server.Open(); server.Subscribe(); refreshGridView(""); } public void refreshClients(string s) { SendOrPostCallback callback = delegate(object state) { refreshGridView(s); }; interfaceContext.Post(callback, s); } public void refreshGridView(string s) { try { userGrid.DataSource = server.refreshDatabaseConnection().Tables[0]; } catch (Exception ex) { MessageBox.Show(ex.ToString()); } } private void buttonAdd_Click(object sender, EventArgs e) { server.addNewAccount(Int32.Parse(inputPIN.Text), Int32.Parse(inputBalance.Text)); } private void Form1_FormClosing(object sender, FormClosingEventArgs e) { try { server.Unsubscribe(); server.Close(); }catch{} } } } The code for the server: namespace SSRfinal_tcp { class Program { static void Main(string[] args) { Console.WriteLine(MessageHandler.dataStamp("The server is starting up")); using (ServiceHost server = new ServiceHost(typeof(BankServer))) { server.Open(); Console.WriteLine(MessageHandler.dataStamp("The server is running")); Console.ReadKey(); } } } [ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Single, InstanceContextMode = InstanceContextMode.PerCall, IncludeExceptionDetailInFaults = true)] public class BankServer : IBankServerService { private static DatabaseLINQConnectionDataContext database = new DatabaseLINQConnectionDataContext(); private static List<IBankServerServiceCallback> subscribers = new List<IBankServerServiceCallback>(); public void Subscribe() { try { IBankServerServiceCallback callback = OperationContext.Current.GetCallbackChannel<IBankServerServiceCallback>(); if (!subscribers.Contains(callback)) subscribers.Add(callback); Console.WriteLine(MessageHandler.dataStamp("A new Bank Administrator has connected")); } catch { Console.WriteLine(MessageHandler.dataStamp("A Bank Administrator has failed to connect")); } } public void Unsubscribe() { try { IBankServerServiceCallback callback = OperationContext.Current.GetCallbackChannel<IBankServerServiceCallback>(); if (subscribers.Contains(callback)) subscribers.Remove(callback); Console.WriteLine(MessageHandler.dataStamp("A Bank Administrator has been signed out from the connection list")); } catch { Console.WriteLine(MessageHandler.dataStamp("A Bank Administrator has failed to sign out from the connection list")); } } public DataSet refreshDatabaseConnection() { var q = from a in database.GetTable<Account>() select a; DataTable dt = q.toTable(rec => new object[] { q }); DataSet data = new DataSet(); data.Tables.Add(dt); Console.WriteLine(MessageHandler.dataStamp("A Bank Administrator has requested a database data listing refresh")); return data; } public void addNewAccount(int pin, int balance) { Account acc = new Account() { PIN = pin, Balance = balance, IsApproved = false }; database.Accounts.InsertOnSubmit(acc); database.SubmitChanges(); database.addNewAccount(pin, balance, false); subscribers.ForEach(delegate(IBankServerServiceCallback callback) { callback.refreshClients("New operation is pending approval."); }); } } } This is really simple and it works for a single window. However, when you open multiple instances of the client window and try to add a new record, the windows that is performing the insert operation crashes with the ExecuteReader error and the " requires an open and available connection. the connection's current state is connecting" bla bla stuff. I have no idea what's going on. Please advise.

  • SEO non-English domain name advice

    - by Dominykas Mostauskis
    I'm starting a website, that is meant for a non-English region, using an alphabet that is a bit different than that of English. Current plan is as follows. The website name, and the domain name, will be in the local language (not English); however, domain name will be spelled in the English alphabet, while the website's title will be the same word(s), but spelled properly with accents. E.g.: 'www.litterat.fr' and 'Littérat'. Does the difference between domain name and website name character use influence the site's SEO? Is it better, SEO-wise, to choose a name that can be spelled the same way in the English alphabet? From my experience, when searching online, invariably, the English alphabet is used, no matter the language, so people will still be searching 'litterat' (without accents and such). Edit: To sum up: Things have been said about IDN (Internationalized domain name). To make it simple, they are second-level domain names that contain language specific characters (LSP)(e.g. www.café.fr). Here you can check what top-level domains support what LSPs. Check initall's answer for more info on using LSPs in paths and queries. To answer my question about how and if search engines relate keywords spelled with and without language specific characters: Google can potentially tell that series and séries is the same keyword. However, (most relevant for words that are spelled differently across languages and have different meanings, like séries), for Google to make the connection (or lack thereof) between e and é, it has to deduce two things: Language that you are searching in. Language of your query. You can specify it manually through Advanced search or it guesses it, sometimes. I presume it can guess it wrong too. The more keywords specific to this language you use the higher Google's chance to guess the language. Language of the crawled document, against which the ASCII version of the word will be compared (in this example – series). Again, check initall's answer for how to help Google in understanding what language your document is in. Once it has that it can tell whether or not these two spellings should be treated as the same keyword. Google has to understand that even though you're not using french (in this example) specific characters, you're searching in French. The reason why I used the french word séries in this example, is that it demonstrates this very well. You have it in French and you have it in English without the accent. So if your search query is ambiguous like our series, unless Google has something more to go on, it will presume that there's no correlation between your search and séries in French documents. If you augment your query to series romantiques (try it), Google will understand that you're searching in French and among your results you'll see séries as well. But this does not always work, you should test it out with your keywords first. For example, if you search series francaises, it will associate francaises with françaises, but it will not associate series with séries. It depends on the words. Note: worth stressing that this problem is very relevant to words that, written in plain ASCII, might have some other meanings in other languages, it is less relevant to words that can be, by a distinct margin, just some one language. Tip: I've noticed that sometimes even if my non-accented search query doesn't get associated with the properly spelled word in a document (especially if it's the title or an important keyword in the doc), it still comes up. I followed the link, did a Ctrl-F search for my non-accented search query and found nothing, then checked the meta-tags in the source and you had the page's title in both accented and non-accented forms. So if you have meta-tags that can be spelled with language specific characters and without, put in both. Footnote: I hope this helps. If you have anything to add or correct, go ahead.

  • Iterative and Incremental Principle Series 4: Iteration Planning – (a.k.a What should I do today?)

    - by llowitz
    Welcome back to the fourth of a five part series on applying the Iteration and Incremental principle.  During the last segment, we discussed how the Implementation Plan includes the number of the iterations for a project, but not the specifics about what will occur during each iteration.  Today, we will explore Iteration Planning and discuss how and when to plan your iterations. As mentioned yesterday, OUM prescribes initially planning your project approach at a high level by creating an Implementation Plan.  As the project moves through the lifecycle, the plan is progressively refined.  Specifically, the details of each iteration is planned prior to the iteration start. The Iteration Plan starts by identifying the iteration goal.  An example of an iteration goal during the OUM Elaboration Phase may be to complete the RD.140.2 Create Requirements Specification for a specific set of requirements.  Another project may determine that their iteration goal is to focus on a smaller set of requirements, but to complete both the RD.140.2 Create Requirements Specification and the AN.100.1 Prepare Analysis Specification.  In an OUM project, the Iteration Plan needs to identify both the iteration goal – how far along the implementation lifecycle you plan to be, and the scope of work for the iteration.  Since each iteration typically ranges from 2 weeks to 6 weeks, it is important to identify a scope of work that is achievable, yet challenging, given the iteration goal and timeframe.  OUM provides specific guidelines and techniques to help prioritize the scope of work based on criteria such as risk, complexity, customer priority and dependency.  In OUM, this prioritization helps focus early iterations on the high risk, architecturally significant items helping to mitigate overall project risk.  Central to the prioritization is the MoSCoW (Must Have, Should Have, Could Have, and Won’t Have) list.   The result of the MoSCoW prioritization is an Iteration Group.  This is a scope of work to be worked on as a group during one or more iterations.  As I mentioned during yesterday’s blog, it is pointless to plan my daily exercise in advance since several factors, including the weather, influence what exercise I perform each day.  Therefore, every morning I perform Iteration Planning.   My “Iteration Plan” includes the type of exercise for the day (run, bike, elliptical), whether I will exercise outside or at the gym, and how many interval sets I plan to complete.    I use several factors to prioritize the type of exercise that I perform each day.  Since running outside is my highest priority, I try to complete it early in the week to minimize the risk of not meeting my overall goal of doing it twice each week.  Regardless of the specific exercise I select, I follow the guidelines in my Implementation Plan by applying the 6-minute interval sets.  Just as in OUM, the iteration goal should be in context of the overall Implementation Plan, and the iteration goal should move the project closer to achieving the phase milestone goals. Having an Implementation Plan details the strategy of what I plan to do and keeps me on track, while the Iteration Plan affords me the flexibility to juggle what I do each day based on external influences thus maximizing my overall success. Tomorrow I’ll conclude the series on applying the Iterative and Incremental approach by discussing how to manage the iteration duration and highlighting some benefits of applying this principle.

  • Connection Refused running multiple environments on Selenium Grid 1.04 via Ubuntu 9.04

    - by ReadyWater
    Hello, I'm writing a selenium grid test suite which is going to be run on a series of different machines. I wrote most of it on my macbook but have recently transfered it over to my work machine, which is running ubuntu 9.04. That's actually my first experience with a linux machine, so I may be missing something very simple (I have disabled the firewall though). I haven't been able to get the multienvironment thing working at all, and I've been trying and manual reviewing for a while. Any recommendations and help would be greatly, greatly appreciated! The error I'm getting when I run the test is: [java] FAILED CONFIGURATION: @BeforeMethod startFirstEnvironment("localhost", 4444, "*safari", "http://remoteURL:8080/tutor") [java] java.lang.RuntimeException: Could not start Selenium session: ERROR: Connection refused I thought it might be the mac refusing the connection, but using wireshark I determined that no connection attempt was made on the mac .

    I have designed Types as follow: class Cricket { string type; Team tm; public Team Team { get { return tm; } set { tm = value; } } public string Type { get { return type; } set { type = value; } } } class Team { string country; Players plr; public Players Players { get {return plr; } set { plr = value; } } public string Country { get { return country; } set { country = value; } } } class Players { string name; DateTime dob; int run; public string Name { get { return name; } set { name = value; } } public DateTime DOB { get { return dob; } set { dob = value; } } public int Run { get { return run; } set { run = value; } } } I have to get the following using LINQ techniques. 1) Youngest all data of the youngest player among all teams 2) Oldest Player of each team 3) The highest run scorer will receive Gold Medal,rest of the players of all team will receive Silver medal. (Please look at the GetPlayer() i have declared var Medal=new String[] {"Gold","Silver"} to associate the Medal ) public void GetPlayer() { var TeamMatrix = new Cricket[] { new Cricket{ Type="Twenty20", Team=new Team{ Country="England", Players=new Players{ DOB=Convert.ToDateTime("01/Jan/1989"), Name="Russel", Run=45}}}, new Cricket{ Type="Twenty20", Team=new Team{ Country="England", Players=new Players{ DOB=Convert.ToDateTime("01/Jan/1991"), Name="Joel", Run=56}}}, new Cricket{ Type="Twenty20", Team=new Team{ Country="Australia", Players=new Players{ DOB=Convert.ToDateTime("01/Jan/1990"), Name="Clark", Run=145}}}, new Cricket{ Type="Twenty20", Team=new Team{ Country="Australia", Players=new Players{ DOB=Convert.ToDateTime("01/Jan/1971"), Name="Bevan", Run=156}}} }; var Medal = new string[] { "Gold", "Silver" }; var tm = (from mat in TeamMatrix select new { mat.Team.Players.DOB }).Max(); Console.WriteLine("Youngest Age={0}",tm); } When I declare var tm = (from mat in TeamMatrix select new { mat.Team.Players.DOB }).Max(); I receive error atleast one object must implement IComparable. What is the actual way to complete the above three tasks? ( Tasks 1 ,2 ,3 are explained above). Thanks to all.

  • ASP.NET MVC - Html.DropDownList - Value not set via ViewData.Model

    - by chrisb
    Have just started playing with ASP.NET MVC and have stumbled over the following situation. It feels a lot like a bug but if its not, an explanation would be appreciated :) The View contains pretty basic stuff <%=Html.DropDownList("MyList", ViewData["MyListItems"] as SelectList)%> <%=Html.TextBox("MyTextBox")%> When not using a model, the value and selected item are set as expected: //works fine public ActionResult MyAction(){ ViewData["MyListItems"] = new SelectList(items, "Value", "Text"); //items is an ienumerable of {Value="XXX", Text="YYY"} ViewData["MyList"] = "XXX"; //set the selected item to be the one with value 'XXX' ViewData["MyTextBox"] = "ABC"; //sets textbox value to 'ABC' return View(); } But when trying to load via a model, the textbox has the value set as expected, but the dropdown doesnt get a selected item set. //doesnt work public ActionResult MyAction(){ ViewData["MyListItems"] = new SelectList(items, "Value", "Text"); //items is an ienumerable of {Value="XXX", Text="YYY"} var model = new { MyList = "XXX", //set the selected item to be the one with value 'XXX' MyTextBox = "ABC" //sets textbox value to 'ABC' } return View(model); } Any ideas? My current thoughts on it are that perhaps when using a model, we're restricted to setting the selected item on the SelectList constructor instead of using the viewdata (which works fine) and passing the selectlist in with the model - which would have the benefit of cleaning the code up a little - I'm just wondering why this method doesnt work.... Many thanks for any suggestions

  • How to validate xml using a .dtd via a proxy and NOT using system.net.defaultproxy

    - by Lanceomagnifico
    Hi, Someone else has already asked a somewhat similar question: http://stackoverflow.com/questions/1888887/validate-an-xml-file-against-a-dtd-with-a-proxy-c-2-0/2766197#2766197 Here's my problem: We have a website application that needs to use both internal and external resources. We have a bunch of internal webservices. Requests to the CANNOT go through the proxy. If we try to, we get 404 errors since the proxy DNS doesn't know about our internal webservice domains. We generate a few xml files that have to be valid. I'd like to use the provided dtd documents to validate the xml. The dtd urls are outside our network and MUST go through the proxy. Is there any way to validate via dtd through a proxy without using system.net.defaultproxy? If we use defaultproxy, the internal webservices are busted, but the dtd validation works.# Here is what I'm doing to validate the xml right now: public static XDocument ValidateXmlUsingDtd(string xml) { var xrSettings = new XmlReaderSettings { ValidationType = ValidationType.DTD, ProhibitDtd = false }; var sr = new StringReader(xml.Trim()); XmlReader xRead = XmlReader.Create(sr, xrSettings); return XDocument.Load(xRead); } Ideally, there would be some way to assign a proxy to the XmlReader much like you can assign a proxy to the HttpWebRequest object. Or perhaps there is a way to programatically turn defaultproxy on or off? So that I can just turn it on for the call to Load the Xdocument, then turn it off again? FYI - I'm open to ideas on how to tackle this - note that the proxy is located in another domain, and they don't want to have to set up a dns lookup to our dns server for our internal webservice addresses. Cheers, Lance

  • ListView item background via custom selector

    - by Gil
    Is it possible to apply a custom background to each Listview item via the list selector? The default selector specifies @android:color/transparent for the state_focused="false" case, but changing this to some custom drawable doesn't affect items that aren't selected. Romain Guy seems to suggest in this answer that this is possible. I'm currently achieving the same affect by using a custom background on each view and hiding it when the item is selected/focused/whatever so the selector is shown, but it'd be more elegant to have this all defined in one place. For reference, this is the selector I'm using to try and get this working: <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_focused="false" android:drawable="@drawable/list_item_gradient" /> <!-- Even though these two point to the same resource, have two states so the drawable will invalidate itself when coming out of pressed state. --> <item android:state_focused="true" android:state_enabled="false" android:state_pressed="true" android:drawable="@drawable/list_selector_background_disabled" /> <item android:state_focused="true" android:state_enabled="false" android:drawable="@drawable/list_selector_background_disabled" /> <item android:state_focused="true" android:state_pressed="true" android:drawable="@drawable/list_selector_background_transition" /> <item android:state_focused="false" android:state_pressed="true" android:drawable="@drawable/list_selector_background_transition" /> <item android:state_focused="true" android:drawable="@drawable/list_selector_background_focus" /> </selector> And this is how I'm setting the selector: <ListView android:id="@android:id/list" android:layout_width="fill_parent" android:layout_height="fill_parent" android:listSelector="@drawable/list_selector_background" /> Thanks in advance for any help!

  • jQuery datepicker returns "inst is null" error when loaded via AJAX

    - by Robert
    I'm loading content via an AJAX call into a table row added to the DOM on the fly. I'm calling the datepicker functionality in my callback function and the calendar shows fine. However, when I click on the date, I get an error: inst is null. Here's my code: $(document).ready(function() { $(".edit").live("click", function() { //Delete previously loaded edit row $("#tempEditRow").remove(); //Get the record id of the row to be edited var recordID = $(this).parent("td").parent("tr").attr("id"); //Add the new row to the document $(this).parent("td").parent("tr").after("<tr id=\"tempEditRow\"><td id=\"tempEditCell\" colspan=\"100\"></td></tr>") //Get a reference to the new row var container = $("#tempEditCell"); //Populate the container populateContainer("/wpm/includes/ajax_editApplication.cfm?id=" + recordID, container); }); }); function populateContainer(ajaxUrl, container) { //Populate the container $.ajax({ url: ajaxUrl, cache: false, success: function(html){ $(container).html(html); $('.datepicker').datepicker(); } }); } I've tried deleting the hasDatepicker class, deleting any references to the datepicker, etc. but nothing is working. Thanks in advance for helping!

  • Seperating Javascript and Html, when dynamically adding html via javascript

    I am currently building a very dynamic table for a list application, which will basically perform basic CRUD functions via AJAX. What I would like to do is separate the visual design and javascript to the point where I can change the design side without touching the JS side. This would only work where the design stays roughly the same(i would like to use it for rapid protyping) Here is an example. <table> <tr><td>record-123</td><td>I am line 123</td><td>delete row</td></tr> <tr><td>record-124</td><td>I am line 124</td><td>delete row</td></tr> <tr><td>record-125</td><td>I am line 125</td><td>delete row</td></tr> <tr><td>add new record</td></tr> </table> Now, when I add a new record, I would like to insert a new row of html, but I would rather not put this html into the javascript file. What I am considering is creating a row like this on the page, near the table. <tr style='visble:none;' id='template-row'><td>record-id</td><td>content-area</td><td>delete row</td></tr> And when I come to add the new row, I search the page for the tags with the id=template-row , and then grab it, do a string replace on it, and then put it in the right place in the page. As long as the design doesn't shift radically, and I keep the placeholder strings the same, it means designs can be quickly modified without touching the js. Can any give any advice on a methodology like this?

  • Subscription Management with Merchant Account via API

    - by Josh
    I'm researching gateways/vendors that provide the ability to create subscription based transitions for merchant accounts. In other words, I want to allow customers to signup for a subscription for a website service that charges once a month. Authorize.Net has an ARB (Automated Recurring Billing) Module. The cost is cheap, $10 a month for the service, with unlimited subscriptions, and they have an API that allows XML or SOAP access to create, update and cancel. The LARGE negative of the service is that it doesn't have elegant way to obtain the current status of a subscription. They can send a daily email with an attached CSV file, or someone can login into the site and review statuses – neither is an enterprise solution. The parent company "CyberSource" has a "Recurring Billing Service" which implies a more robust solution, including API access to subscription information. I’m currently waiting for a sales call back on costs related to the service. I also looked at PayPal's Recurring Billing Service, but that appears to require that users are redirected to the PayPal site to signup for the subscription -- again, not an an elegant solution. Does anyone know of any other vendors/gateways that offer subscription service, that meet the following criteria: Vendor/Gateway must host the credit card number and be PCI compliant Have an API that accessible via a Web Service, Post over HTTPS or SOAP Have an API that allows querying the status of subscriptions and/or the ability to query for activity since a certain date. Thanks in advance for your suggestions.

  • search form in html/php via ajax

    - by fusion
    i've a search form wherein the database query has been coded in php and the html file calls this php file via ajax to display the results in the search form. the problem is, i would like the result to be displayed in the same form as search.html; yet while the ajax works, it goes to search.php to display the results. search.html: <!DOCTYPE html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <script src="scripts/search_ajax.js" type="text/javascript"></script> </head> <body> <form id="submitForm" method="post"> <div class="wrapper"> <div class="field"> <input name="search" id="search" /> </div><br /> <input id="button1" type="submit" value="Submit" class="submit" onclick="run_query();" /><br /> </div> <div id="searchContainer"> </div> </form> </body> </html> if i add action="search.php" to the form tag, it displays the result but on search.php. i'd like it to display on the same form [i.e search.html, and not search.php] if i just add the javascript function [as done above], it displays nothing on search.html

  • Loading GMaps via ajax

    - by Marco
    Hi to all, I'm loading a page containing a GMaps using the ajax() method of jQuery. The HTML page i'm loading is: <script src="http://maps.google.com/maps?file=api&amp;v=2&amp;sensor=false&amp;key=MY_API_KEY" type="text/javascript"></script> <script type="text/javascript"> $(document).ready(function() { if (GBrowserIsCompatible()) { var map = new GMap2(document.getElementById("map_canvas")); var geocoder = new GClientGeocoder(); geocoder.getLatLng("San Francisco, California",function(point) { if (point) { map.setCenter(point, 7); } }); map.setUIToDefault(); } }); </script> <div id="map_canvas"></div> After retrieving this page, I'm setting its contents to a div using the html() method. The map is not showed, while other pages containing scripts, loaded in the same way, are correctly shown. Is this a specific issue about GMaps, that doesn't allow to be loaded via an ajax request? Thanks

  • Accessing Item Fields via Sitecore Web Service

    - by Catch
    I am creating items on the fly via Sitecore Web Service. So far I can create the items from this function: AddFromTemplate And I also tried this link: http://blog.hansmelis.be/2012/05/29/sitecore-web-service-pitfalls/ But I am finding it hard to access the fields. So far here is my code: public void CreateItemInSitecore(string getDayGuid, Oracle.DataAccess.Client.OracleDataReader reader) { if (getDayGuid != null) { var sitecoreService = new EverBankCMS.VisualSitecoreService(); var addItem = sitecoreService.AddFromTemplate(getDayGuid, templateIdRTT, "Testing", database, myCred); var getChildren = sitecoreService.GetChildren(getDayGuid, database, myCred); for (int i = 0; i < getChildren.ChildNodes.Count; i++) { if (getChildren.ChildNodes[i].InnerText.ToString() == "Testing") { var getItem = sitecoreService.GetItemFields(getChildren.ChildNodes[i].Attributes[0].Value, "en", "1", true, database, myCred); string p = getChildren.ChildNodes[i].Attributes[0].Value; } } } } So as you can see I am creating an Item and I want to access the Fields for that item. I thought that GetItemFields will give me some value, but finding it hard to get it. Any clue?

  • Prerequisites for Account management via an IPhone App?

    - by Icky
    Hello. I have been reading a couple of threads for this topic on this site. I want to create an App, which communicates with a server and has the following features: the User can create/manage an account on the server the App communicates with the server via a secure connection the User is updated about important news through messages From what I understood so far, I need to take care of the following: establish a secure connection with the server send account information(user data, password) to the server and authenticate the client side management and encryption of account data/information is handled by the server, so the App only sends data, the server stores/encrypts (no need for me to take care of anything) So far, I think, I have covered the most important features. I have read, that NSURLConnection can be used, to send the authentication data. But how is further communication ensured? And how is the encryption managed? Are there any useful tutorials on this, because this is the first time I delve into this topic, and any guidance is greatly appreciated! Also, if I have missed anything important (e.g. with managing accounts) please tell me.

  • Maintain order of messages via proxies to app servers

    - by David Turner
    Hi, I am receiving messages from a 3rd party via a http post, and it is important that the order the messages hit our infrastructure is maintained through the load balancers and proxies until it hits our application server. Quick Diagram. (proxies in place due to security requirements.) [ACE load balancer] - [2 proxies] - [Application Servers] or maybe [ACE load balancer] - [2 proxies] - [ACE load balancer] - [Application Servers] My idea was that I would setup the load balancers in active-passive mode, to force all messages to use one proxy, and then both the proxies would hit a second load balancer that would be configured in active passive to hit one application server. Whilst the above is not ideal, it does give me resilience, and once the message is in my app servers, I enter a stateless world, and load balance across both nodes of my cluster. However, I am concerned that even a single proxy could send messages out of order, perhaps if 2 messages are recived very close together, message 2 might get processed faster than message 1. Is this possible? Likely? Is there a simple open source proxy (MOD_PROXY?) that can be easily configured to just pass messages through it, and to guarantee to send the messages through in the order they are received. If so which, and finally links to how I should configure it would be great. In fact any links to articles around avoiding "out of order" messages using hardware would be gratefully received. Thanks, ps for those that are interested, the app is a java spring integration application currently on a appliation server.

  • CSS semantics; selecting elements directly or via order

    - by Joshua Cody
    Perhaps this question has been asked elsewhere, but I'm unable to find it. With HTML5 and CSS3 modules inching closer, I'm getting interested in a discussion about the way we write CSS. Something like this where selection is done via element order and type is particularly fascinating. The big advantage to this method seems to be complete modularization of HTML and CSS to make tweaks and redesigns simpler. At the same time, semantic IDs and classes seem advantageous for sundry reasons. Particularly, direct linking, JS targeting, and shorter CSS selectors. Also, it seems selector length might be an issue. For instance, I just wrote the following, which would be admittedly easier using some semantic HTML5 elements: body>div:nth-child(2)>div:nth-child(2)>ul:nth-child(2)>li:last-child So what say you, Stack Overflow? Is the future of CSS writing focused on element order and type? Or are IDs and classes and the current ways here to stay? (I'm well aware the IDs and classes have their place, although I am interested to hear more ways you think they'll continue to be necessary. The discussion I'm interested in is bigger-picture and the ways writing CSS is changing.)
