  • Pure Front end JavaScript with Web API versus MVC views with ajax

    - by eyeballpaul
    This was more a discussion for what peoples thoughts are these days on how to split a web application. I am used to creating an MVC application with all its views and controllers. I would normally create a full view and pass this back to the browser on a full page request, unless there were specific areas that I did not want to populate straight away and would then use DOM page load events to call the server to load other areas using AJAX. Also, when it came to partial page refreshing, I would call an MVC action method which would return the HTML fragment which I could then use to populate parts of the page. This would be for areas that I did not want to slow down initial page load, or areas that fitted better with AJAX calls. One example would be for table paging. If you want to move on to the next page, I would prefer it if an AJAX call got that info rather than using a full page refresh. But the AJAX call would still return an HTML fragment. My question is. Are my thoughts on this archaic because I come from a .net background rather than a pure front end background? An intelligent front end developer that I work with, prefers to do more or less nothing in the MVC views, and would rather do everything on the front end. Right down to web API calls populating the page. So that rather than calling an MVC action method, which returns HTML, he would prefer to return a standard object and use javascript to create all the elements of the page. The front end developer way means that any benefits that I normally get with MVC model validation, including client side validation, would be gone. It also means that any benefits that I get with creating the views, with strongly typed html templates etc would be gone. I believe this would mean I would need to write the same validation for front end and back end validation. The javascript would also need to have lots of methods for creating all the different parts of the DOM. For example, when adding a new row to a table, I would normally use the MVC partial view for creating the row, and then return this as part of the AJAX call, which then gets injected into the table. By using a pure front end way, the javascript would would take in an object (for, say, a product) for the row from the api call, and then create a row from that object. Creating each individual part of the table row. The website in question will have lots of different areas, from administration, forms, product searching etc. A website that I don't think requires to be architected in a single page application way. What are everyone's thoughts on this? I am interested to hear from front end devs and back end devs.

  • going from closed-source to open-source [closed]

    - by mspoerr
    I am thinking of releasing the source code of my application (Freeware at the moment). It is written in C++ with VisualStudio 2008 and all used 3rd-party libs are free or open-source and platform independent. The idea to release the source-code is very old, but till now I did not want to show the code because I am not sure if it is nice/well designed (I am not a professional developer), but the application is growing and help would be very welcome, but I want to keep control... What do I need to consider? Is there any best practice for this scenario? The code itself is one thing, but there is much more like license, documentation, project settings, 3rd party libs, platform (Sourceforge, other?)

  • 401 Using Multiple Authentication methods IE 10 only

    - by jon3laze
    I am not sure if this is more of a coding issue or server setup issue so I've posted it on stackoverflow and here... On our production site we've run into an issue that is specific to Internet Explorer 10. I am using jQuery doing an ajax POST to a web service on the same domain and in IE10 I am getting a 401 response, IE9 works perfectly fine. I should mention that we have mirrored code in another area of our site and it works perfectly fine in IE10. The only difference between the two areas is that one is under a subdomain and the other is at the root level. www.my1stdomain.com vs. portal.my2nddomain.com The directory structure on the server for these are: \my1stdomain\webservice\name\service.aspx \portal\webservice\name\service.aspx Inside of the \portal\ and \my1stdomain\ folders I have a page that does an ajax call, both pages are identical. $.ajax({ type: 'POST', url: '/webservice/name/service.aspx/function', cache: false, contentType: 'application/json; charset=utf-8', dataType: 'json', data: '{ "json": "data" }', success: function() { }, error: function() { } }); I've verified permissions are the same on both folders on the server side. I've applied a workaround fix of placing the <meta http-equiv="X-UA-Compatible" value="IE=9"> to force compatibility view (putting IE into compatibility mode fixes the issue). This seems to be working in IE10 on Windows 7, however IE 10 on Windows 8 still sees the same issue. These pages are classic asp with the headers that are being included, also there are no other meta tags being used. The doctype is being specified as <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//" "http://www.w3.org/TR/html4/loose.dtd"> on the portal page and <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> on the main domain. UPDATE1 I used Microsoft Network Monitor 3.4 on the server to capture the request. I used the following filter to capture the 401: Property.HttpStatusCode.StringToNumber == 401 This was the response - Http: Response, HTTP/1.1, Status: Unauthorized, URL: /webservice/name/service.aspx/function Using Multiple Authetication Methods, see frame details ProtocolVersion: HTTP/1.1 StatusCode: 401, Unauthorized Reason: Unauthorized - ContentType: application/json; charset=utf-8 - MediaType: application/json; charset=utf-8 MainType: application/json charset: utf-8 Server: Microsoft-IIS/7.0 jsonerror: true - WWWAuthenticate: Negotiate - Authenticate: Negotiate WhiteSpace: AuthenticateData: Negotiate - WWWAuthenticate: NTLM - Authenticate: NTLM WhiteSpace: AuthenticateData: NTLM XPoweredBy: ASP.NET Date: Mon, 04 Mar 2013 21:13:39 GMT ContentLength: 105 HeaderEnd: CRLF - payload: HttpContentType = application/json; charset=utf-8 HTTPPayloadLine: {"Message":"Authentication failed.","StackTrace":null,"ExceptionType":"System.InvalidOperationException"} The thing here that really stands out is Unauthorized, URL: /webservice/name/service.aspx/function Using Multiple Authentication Methods With this I'm still confused as to why this only happens in IE10 if it's a permission/authentication issue. What was added to 10, or where should I be looking for the root cause of this?

  • UNHCR and Stanyslas Matayo Receive Duke's Choice Award 2012

    - by Geertjan
    This year, NetBeans Platform applications winning Duke's Choice Awards were not only AgroSense, by Ordina in the Netherlands, and the air command and control system by NATO... but also Level One, the UNHCR registration and emergency management system. Unfortunately, Stanyslas Matayo, the architect and lead engineer of Level One, was unable to be at JavaOne to receive his award. It would have been really cool to meet him in person, of course, and he would have joined the NetBeans Party and NetBeans Day, as well as the NetBeans Platform panel discussions that happened at various stages throughout JavaOne. Instead, he received his award at Oracle Day 2012 Nairobi, some days ago, where he presented Level One and received the Duke's Choice Award: Level One is the UNHCR (UN refugee agency) application for capturing information on the first level details of refugees in an emergency context. In its recently released initial version, the application was used in Niger to register information about families in emergency contexts. Read more about it here and see the screenshot below. Congratulations, Stanyslas, and the rest of the development team working on this interesting and important project!

  • AJI Report with Nat Ryan&ndash;Discussion about Game Development with Corona Labs SDK

    - by Jeff Julian
    We sat down with Nat Ryan of Fully Croisened to talk about Game Development and the Corona Labs framework. The Corona SDK is a platform that allows you to write mobile games or applications using the Lua language and deploy to the iOS and Android platforms. One of the great features of Corona is the compilation output is a native application and not a hybrid application. Corona is very centered around their developer community and there are quite a few local meetups focused on the helping other developers use the platform. The community and Corona site offers a great number of resources and samples that will help you get started in a matter of a few days. If you are into Game Development and want to move towards mobile, or a business developer looking to turn your craft back into a hobby, check out this recording and Corona Labs to get started.   Download the Podcast   Site: AJI Report – @AJISoftware Site: Fully Croisened Twitter: @FullyCroisened Site: Corona Labs

  • CodeStock 2012 Review: Michael Eaton( @mjeaton ) - 3 Simple Things for Increased Productivity

    3 Simple Things for Increased ProductivitySpeaker: Michael EatonTwitter: @mjeatonBlog: http://mjeaton.net/blog This was the first time I had seen Michael Eaton speak but have hear a lot of really good things about his speaking abilities. Needless to say I was really looking forward to his session. He basically addressed the topic of distractions and how they can decrease or increase your productivity as a developer. He makes the case that in order to become more productive you must block/limit all distractions. For example, he covered his top distractions as a developer. Top Distractions Social Media(Twitter, Reddit, Facebook) Wiki sites Phone Email Video Games Coworkers, Friends, Family Michael stated that he uses various types of music to help him block out these distractions in order for him to get into his coding zone. While he states that music works for him, he also notes that he knows of others that cannot really work with music. I have to say I am in the latter group because I require a quiet environment in order to work. A few session attendees also recommended listening to really loud white noise or music in another language other than your own. This allows for less focus to be placed on words being sung compared to the rhythmic beats being played. I have to say that I have not tried these suggestions yet but will in the near future. However, distractions can be very beneficial to productivity in that they give your mind a chance to relax and not think about the issues at hand. He spoke highly of taking vacations, and setting boundaries at work so that develops prevent the problem of burnout. One way he suggested that developer’s combat distractions is to use the Pomodoro technique. In his example he selects one task to do for 20 minutes and he can only do that task during that time. He ignores all other distractions until this task or time limit is complete. After it is completed he allows himself to relax and distract himself for another 5- 10 minutes before his next Pomodoro. This allows him to stay completely focused on a task and when the time is up he can then focus on other things.

  • Windows Embedded Forums

    - by Luca Calligaris
    Here are the forums about Windows Embedded: Windows Embedded Standard Windows Embedded Compact Platform Development Windows Embedded Compact Managed Application Development Windows Embedded Compact Native Application Development The first forum has been online for some time while those about Windows Embedded Compact have been welcomed by Olivier Bloch a couple of hours ago. As I discuss in the previous post the public MS newsgroups will close between June 1, 2010 and October 1, 2010, starting from those with less traffic. The embedded NG's will be probably close at the beginning of the period since, for some reasons I do not understand, they're not so popular as those devoted to, let's say, Office. The forums will substitute the newsgroups so prepare to switch over soon!

  • Context Issue in ASP.NET MVC 3 Unobtrusive Ajax

    - by imran_ku07
        Introduction:          One of the coolest feature you can find in ASP.NET MVC 3 is Unobtrusive Ajax and Unobtrusive Client Validation which separates the javaScript behavior and functionality from the contents of a web page. If you are migrating your ASP.NET MVC 2 (or 1) application to ASP.NET MVC 3 and leveraging the Unobtrusive Ajax feature then you will find that the this context in the callback function is not the same as in ASP.NET MVC 2(or 1). In this article, I will show you the issue and a simple solution.       Description:           The easiest way to understand the issue is to start with an example. Create an ASP.NET MVC 3 application. Then add the following javascript file references inside your page,   <script src="@Url.Content("~/Scripts/MicrosoftAjax.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/MicrosoftMvcAjax.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/jquery-1.4.4.min.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript"></script>             Then add the following lines into your view,   @Ajax.ActionLink("About", "About", new AjaxOptions { OnSuccess = "Success" }) <script type="text/javascript"> function Success(data) { alert(this.innerHTML) } </script>              Next, disable Unobtrusive Ajax feature from web.config,   <add key="UnobtrusiveJavaScriptEnabled" value="false"/>              Then run your application and click the About link, you will see the alert window with "About" message on the screen. This shows that the this context in the callback function is the element which is clicked. Now, let's see what will happen when we leverage Unobtrusive Ajax feature. Now enable Unobtrusive Ajax feature from web.config,     <add key="UnobtrusiveJavaScriptEnabled" value="true"/>              Then run your application again and click the About link again, this time you will see the alert window with "undefined" message on the screen. This shows that the this context in the callback function is not the element which is clicked. Here, this context in the callback function is the Ajax settings object provided by jQuery. This may not be desirable because your callback function may need the this context as the element which triggers the Ajax request. The easiest way to make the this context as the element which triggers the Ajax request is to add this line in jquery.unobtrusive-ajax.js file just before $.ajax(options) line,   options.context = element;              Then run your application again and click the About link again, you will find that the this context in the callback function remains same whether you use Unobtrusive Ajax or not.       Summary:          In this article I showed you a breaking change and a simple workaround in ASP.NET MVC 3. If you are migrating your application from ASP.NET MVC 2(or 1) to ASP.NET MVC 3 and leveraging Unobtrusive Ajax feature then you need to consider this breaking change. Hopefully you will enjoy this article too.     SyntaxHighlighter.all()

  • Compute Scalars, Expressions and Execution Plan Performance

    - by Paul White
    The humble Compute Scalar is one of the least well-understood of the execution plan operators, and usually the last place people look for query performance problems. It often appears in execution plans with a very low (or even zero) cost, which goes some way to explaining why people ignore it. Some readers will already know that a Compute Scalar can contain a call to a user-defined function, and that any T-SQL function with a BEGIN…END block in its definition can have truly disastrous consequences...(read more)

  • Delegates in c#

    - by Jalpesh P. Vadgama
    I have used delegates in my programming since C# 2.0. But I have seen there are lots of confusion going on with delegates so I have decided to blog about it. In this blog I will explain about delegate basics and use of delegates in C#. What is delegate? We can say a delegate is a type safe function pointer which holds methods reference in object. As per MSDN it's a type that references to a method. So you can assign more than one methods to delegates with same parameter and same return type. Following is syntax for the delegate public delegate int Calculate(int a, int b); Here you can see the we have defined the delegate with two int parameter and integer parameter as return parameter. Now any method that matches this parameter can be assigned to above delegates. To understand the functionality of delegates let’s take a following simple example. using System; namespace Delegates { class Program { public delegate int CalculateNumber(int a, int b); static void Main(string[] args) { int a = 5; int b = 5; CalculateNumber addNumber = new CalculateNumber(AddNumber); Console.WriteLine(addNumber(5, 6)); Console.ReadLine(); } public static int AddNumber(int a, int b) { return a + b; } } } Here in the above code you can see that I have created a object of CalculateNumber delegate and I have assigned the AddNumber static method to it. Where you can see in ‘AddNumber’ static method will just return a sum of two numbers. After that I am calling method with the help of the delegates and printing out put to the console application. Now let’s run the application and following is the output as expected. That’s it. You can see the out put of delegates after adding a number. This delegates can be used in variety of scenarios. Like in web application we can use it to update one controls properties from another control’s action. Same you can also call a delegates whens some UI interaction done like button clicked. Hope you liked it. Stay tuned for more. In next post I am going to explain about multicast delegates. Till then happy programming.

    http://fmwdocs.us.oracle.com/doclibs/fmw/E10285_01/appslib7/web.1111/b31974/adding_security.htm#BGBGJEAH At design time, JDeveloper saves all policy store and identity store changes in a single file for the entire application. In the development environment, this is the jazn-data.xml file. After you configure the jazn-data.xml file using the editors, you can run the application in Integrated WebLogic Server and the contents of the policy store will be added to the domain-level store, the system-jazn-data.xml file, while the test users will be migrated to the embedded LDAP server that Integrated WebLogic Server uses for its identity store. The domain-level store allows you to test the security implementation by logging on as test users that you have created. looks like above part did went well with me, apart from following all instruction provided in doc, I need to create users from adminconsole in security-realms-Users and Groups sections to successfully login to pages.

  • Visio Architecture Diagram [closed]

    - by Mike
    I am using Visio to create an architecture diagram similar to the following Windows block diagram: Are there components available in Visio to make a diagram like this? I can do it manually by using the open/closed bar shape from Blocks and then adding the text as textboxes but it means I have to worry about sizing/offsetting text for each black box. Is anyone aware of whether there is some built-in shape already for this?

  • Looking into ASP.Net MVC 4.0 Mobile Development - part 2

    - by nikolaosk
    In this post I will be continuing my discussion on ASP.Net MVC 4.0 mobile development. You can have a look at my first post on the subject here . Make sure you read it and understand it well before you move one reading the remaining of this post. I will not be writing any code in this post. I will try to explain a few concepts related to the MVC 4.0 mobile functionality. In this post I will be looking into the Browser Overriding feature in ASP.Net MVC 4.0. By that I mean that we override the user agent for a given user session. This is very useful feature for people who visit a site through a device and they experience the mobile version of the site, but what they really want is the option to be able to switch to the desktop view. "Why they might want to do that?", you might wonder.Well first of all the users of our ASP.Net MVC 4.0 application will appreciate that they have the option to switch views while some others will think that they will enjoy more the contents of our website with the "desktop view" since the mobile device they view our site has a quite large display.  Obviously this is only one site. These are just different views that are rendered.To put it simply, browser overriding lets our application treat requests as if they were coming from a different browser rather than the one they are actually from. In order to do that programmatically we must have a look at the System.Web.WebPages namespace and the classes in it. Most specifically the class BrowserHelpers. Have a look at the picture below   In this class we see some extension methods for HttpContext class.These methods are called extensions-helpers methods and we use them to switch to one browser from another thus overriding the current/actual browser. These APIs have effect on layout,views and partial views and will not affect any other ASP.Net Request.Browser related functionality.The overridden browser is stored in a cookie. Let me explain what some of these methods do. SetOverriddenBrowser() -  let us set the user agent string to specific value GetOverriddenBrowser() -  let us get the overridden value ClearOverriddenBrowser() -  let us remove any overridden user agent for the current request   To recap, in our ASP.Net MVC 4.0 applications when our application is viewed in our mobile devices, we can have a link like "Desktop View" for all those who desperately want to see the site with in full desktop-browser version.We then can specify a browser type override. My controller class (snippet of code) that is responsible for handling the switching could be something like that. public class SwitchViewController : Controller{ public RedirectResult SwitchView(bool mobile, string returnUrl){if (Request.Browser.IsMobileDevice == mobile)HttpContext.ClearOverriddenBrowser();elseHttpContext.SetOverriddenBrowser(mobile ? BrowserOverride.Mobile : BrowserOverride.Desktop);return Redirect(returnUrl);}} Hope it helps!!!!
