  • jQuery - .Ready fires on div tag not in the page

    - by Anders Juul
    Dear all, I have implemented below function in a separate .js script file which I load in my main page (Asp.net mvc). The call back to server is rather costly but ok if specifically requested on the sub-page / content page on which my div tag needs to be filled. My problem is that the code runs on every page, including pages where the div tag is not present. How can I remedy my code? Any comments welcome, Thanks, Anders, Denmark jQuery("divStatWrapper").ready(function() { jQuery.getJSON("/Statistics/GetPointsDevelopment", function(json) { jQuery("#divStatWrapper #divStatLoading").fadeOut(1000); var jsonPoints = new Array(); jQuery.each(json.Points, function(i, item) { jsonPoints.push(item.PlayerPoints ); }); jsonPoints.reverse(); var api = new jGCharts.Api(); jQuery('<img>') .attr('src', api.make({ data : jsonPoints, type : "lc", size : "600x250" })) .appendTo("#divStatContents"); jQuery("#divStatWrapper #divStatContents").fadeIn(1000); }); });

  • Notifying view controller when subview touch events occur.

    - by Nebs
    I have a UIViewController whose view has a custom subview. This custom subview needs to track touch events and report swipe gestures. Currently I put touchesBegan, touchesMoved, touchesEnded and touchesCancelled in the subview class. With some extra logic I am able to get swipe gestures and call my handleRightSwipe and handleLeftSwipe methods. So now when I swipe within the subview it calls its local swipe handling methods. This all works fine. But what I really need is for the handleRightSwipe and handleLeftSwipe methods to be in the view controller. I could leave them in the subview class but then I'd have to bring in all the logic and data as well and that kind of breaks the MVC idea. So my question is is there a clean way to handle this? Essentially I want to keep my touch event methods in the subview so that they only trigger for that specific view. But I also want the view controller to be informed when these touch events (or in this case swipe gestures) occur. Any ideas? Thanks.

  • Using db4o with multiple application instances under medium trust

    - by Anders Fjeldstad
    I recently stumbled over the object database engine db4o which I think looks really interesting. I would like to use it in an ASP.NET MVC application that will be deployed to a shared hosting environment under medium trust. Because of the trust level, I'm restricted to using db4o in embedded/in-process mode. That in itself should be no problem, but the hosting provider also transparently runs each web application in multiple (load-balanced) server instances with shared storage, which I would say is normally a very nice feature for a $10/month hoster. However, since an instance of a db4o server with write access (whether in-process or networked) locks the underlying database file, having multiple instances of the application using the same file won't work (or at least I can't see how it would). So the question is: is it possible to use db4o in this specific environment? I have considered letting each application have its own database which is synchronized with a master database using replication (dRS), but that approach will most likely end up with very frequent bi-directional replication (read master changes at beginning of each request, write to master after each change) which I don't think will be very efficient. Summary of the web application/environment characteristics: Read-intensive (but not entirely read-only) Some delay (a few seconds) is acceptible between the time that a change is made and the time when the change shows up in all the application instances' data Must run in medium trust No guarantee that the load-balancer uses "sticky sessions" All suggestions are much appreciated!

  • Web-based clients vs thick/rich clients?

    - by rudolfv
    My company is a software solutions provider to a major telecommunications company. The environment is currently IBM WebSphere-based with front-end IBM Portal servers talking to a cluster of back-end WebSphere Application Servers providing EJB services. Some of the portlets use our own home-grown MVC-pattern and some are written in JSF. Recently we did a proof-of-concept rich/thick-client application that communicates directly with the EJB's on the back-end servers. It was written in NetBeans Platform and uses the WebSphere application client library to establish communication with the EJB's. The really painful bit was getting the client to use secure JAAS/SSL communications. But, after that was resolved, we've found that the rich client has a number of advantages over the web-based portal client applications we've become accustomed to: Enormous performance advantage (CORBA vs. HTTP, cut out the Portal Server middle man) Development is simplified and faster due to use of NetBeans' visual designer and Swing's generally robust architecture The debug cycle is shortened by not having to deploy your client application to a test server No mishmash of technologies as with web-based development (Struts, JSF, JQuery, HTML, JSTL etc., etc.) After enduring the pain of web-based development (even JSF) for a while now, I've come to the following conclusion: Rich clients aren't right for every situation, but when you're developing an in-house intranet-based solution, then you'd be crazy not to consider NetBeans Platform or Eclipse RCP. Any comments/experiences with rich clients vs. web clients?

  • Thrift,.NET,Cassandra - Is this is right combination?

    - by Vadi
    I've been evaluating technology stack for developing a social network based application. Below are the stack I think could well suitable for this application type of application: GUI -- ASP.NET MVC, Flash (Flex) Business Services -- Thrift based services One of the advantage of using Thrift is to solve scaling problems that will come in future when the user base increases rapidly. All the business logic can be exposed as a services using REST,JSON etc., This also allows us to go with C++ or Erlang based services when situation demands. Database -- mySQL, CasSandara mySQL can be used for storing the data which needs to be persisted. Cassandara will be used for storing global identifiers to the persisted data. Since Cassandara is also very good at scaling by introducing more nodes this will leverage Thrift based services as well. And also there is native support between Cassandara and Thrift Cache Server -- Memcached Any requests from Business Services will only talk to Memcached if any non-dirty data is required, otherwise there will be some background jobs that will invalidate the cache from database. The question is: Is the Thrift which is open-sourced one is production-ready? Is it the right stack for services layer to choose when the application (GUI) is primarily gets developed in ASP.NET and DB is mysql? Is there any other caveats that anyone here experienced? One of the main objective behind this stack is to easily scale up with more nodes and also this helps us to use Linux boxes, it will reduce our cost significantly Thoughts please ..

  • How to Global onRouteRequest directly to onBadRequest?

    - by virtualeyes
    EDIT Came up with this to sanitize URI date params prior to passing off to Play router val ymdMatcher = "\\d{8}".r // matcher for yyyyMMdd URI param val ymdFormat = org.joda.time.format.DateTimeFormat.forPattern("yyyyMMdd") def ymd2Date(ymd: String) = ymdFormat.parseDateTime(ymd) override def onRouteRequest(r: RequestHeader): Option[Handler] = { import play.api.i18n.Messages ymdMatcher.findFirstIn(r.uri) map{ ymd=> try { ymd2Date( ymd); super.onRouteRequest(r) } catch { case e:Exception => // kick to "bad" action handler on invalid date Some(controllers.Application.bad(Messages("bad.date.format"))) } } getOrElse(super.onRouteRequest(r)) } ORIGINAL Let's say I want to return a BadRequest result type for all /foo URIs: override def onBadRequest(r: RequestHeader, error: String) = { BadRequest("Bad Request: " + error) } override def onRouteRequest(r: RequestHeader): Option[Handler] = { if(r.uri.startsWith("/foo") onBadRequest("go away") else super.onRouteRequest(r) } Of course does not work, since the expected return type is Option[play.api.mvc.Handler] What's the idiomatic way to deal with this, create a default Application controller method to handle filtered bad requests? Ideally, since I know in onRouteRequest that /foo is in fact a BadRequest, I'd like to call onBadRequest directly. Should note that this is a contrived example, am actually verifying a URI yyyyMMdd date param, and BadRequest-ing if it does not parse to a JodaTime instance -- basically a catch-all filter to sanitize a given date param rather than handling on every single controller method call, not to mention, avoiding cluttering up application log with useless stack traces re: invalid date parse conversions (have several MBs of these junk trace entries accruing daily due to users pointlessly manipulating the uri date in attempts to get at paid subscriber content)

  • Are eCommerce platforms worth it for large scale systems?

    - by codeflunky
    My company and I are building a new system for a relatively large client. We are going to be replacing their entire system, which includes some eCommerce aspects to it among many other things. It is not a typical public shopping site, and there are many things about the system (both back end and front end) that are quite different. Some of the people I work for are convinced that we should be using a third party product to implement the eCommerce pieces (shopping cart, catalog management). Their opinion is that it is a solved problem, and we shouldn't have to reinvent it. Given that direction, I have reviewed around ten different .NET based eCommerce platforms, and I struggle to imagine how we will be able to smoothly integrate any of them without a lot of friction. They are so all-encompassing that I feel like they are probably better suited for implementing simple shopping sites rather than larger systems that happen to have some eCommerce aspects to them. We have a really nice architecture planned for everything else (Entity Framework, ASP.NET MVC, etc.), and my gut is telling me that trying to introduce a third party platform will cause unnecessary fragmentation and difficulty. I would love to hear some opinions from people who have been there. Have you used a third party platform for eCommerce? Was it a typical shopping site or something different? Did you feel it was a help or a hinderance? Thanks.

  • LogonUser using LOGON32_LOGON_NEW_CREDENTIALS works against remote untrusted domain machine

    - by Jiho Han
    So between the two machines, there is no trust - they are in different domains. I've successfully connected to the remote machine using LogonUser API using logon type, *LOGON32_LOGON_NEW_CREDENTIALS*. I am able to retrieve the content of a directory using the UNC share, and create a file stream to "download" the file. So far so good. The only issue is that it seems, LogonUser fails unless there is an already open session. Let me clarify that. I found that the ASP.NET MVC page was not working this morning, specifically the page that retrieves the file list from this remote machine using LogonUser. I look at the log and I see in the stacktrace, *System.IO.__Error.WinIOError* above Directory.GetFiles call. I then remoted into the web server and tried to open the remote folder in the explorer using the same login/password used by the web site. It went through and I could see the files. I opened up the command prompt, type in net use, and I see that there is an open connection to the remote machine. Then I went back to the page and suddenly the page is working again. So, at this point, I am not exactly sure if the LogonUser is working as expected or not. If the call requires that a network connection opened first by other means, then this is certainly not satisfactory. Does anyone know what may be happening or suggest a workaround?

  • log4net affecting other projects which don't even use it

    - by Graeme
    I'm seeing something really strange happening with some projects I'm working on. I used log4net in an MVC web site and this was working great. I then was working on a totally unrelated Console application which uses the SharePoint API and as soon as I include the following line (other lines don't cause the problem) SPLimitedWebPartManager spWebPartManager = web.GetLimitedWebPartManager("http://blah/blah.aspx?PageView=Shared", System.Web.UI.WebControls.WebParts.PersonalizationScope.Shared); I get the following message in the console app log4net:ERROR XmlConfigurator: Failed to find configuration section 'log4net' in the application's .config file. Check your .config file for the <log4net> and < configSections> elements. The configuration section should look like: <section n ame="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" / > log4net:ERROR XmlConfigurator: Failed to find configuration section 'log4net' in the application's .config file. Check your .config file for the <log4net> and < configSections> elements. The configuration section should look like: <section n ame="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" / > I get this twice after a small delay. The delay is probably the request to get the web part manager from the page but I'm not sure why this log4net error is showing up in this project. I've gone through the code and bin folders etc. and found no trace of any log4net mentions. Any ideas why this might be happening?

  • Castle Windsor upgrade causes TypeLoadException for generic types

    - by Neil Barnwell
    I have the following mapping in my Castle Windsor xml file which has worked okay (unchanged) for some time: <component id="defaultBasicRepository" service="MyApp.Models.Repositories.IBasicRepository`1, MyApp.Models" type="MyApp.Models.Repositories.Linq.BasicRepository`1, MyApp.Models" lifestyle="perWebRequest"/> I got this from the Windsor documentation at http://www.castleproject.org/container/documentation/v1rc3/usersguide/genericssupport.html. Since I upgraded Windsor, I now get the following exception at runtime: Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.TypeLoadException: GenericArguments[0], 'T', on 'MyApp.Models.Repositories.Linq.BasicRepository`1[TEntity]' violates the constraint of type parameter 'TEntity'. Source Error: Line 44: public static void ConfigureIoC() Line 45: { Line 46: var windsor = new WindsorContainer("Windsor.xml"); Line 47: Line 48: ServiceLocator.SetLocatorProvider(() = new WindsorServiceLocator(windsor)); I'm using ASP.NET MVC 1.0, Visual Studio 2008 and Castle Windsor as downloaded from http://sourceforge.net/projects/castleproject/files/InversionOfControl/2.1/Castle-Windsor-2.1.1.zip/download Can anyone shed any light on this? I'm sure the upgrade of Castle Windsor is what caused it - it's been working well for ages.

  • Suggestions for entering mobile development -- pure iPhone SDK, Android SDK, Mono Touch or Titanium

    - by Tom Cabanski
    I am entering mobile development. I have been working primarily in .NET since 1.0 came out in beta. Before that, I was mostly a C++ and Delphi guy and still dabble in C++ from time to time. I do web apps quite a bit so I am reasonably proficient with Javascript, JQuery and CSS. I have also done a few Java applications. I started web programming with CGI and live mostly in the ASP.NET MVC world these days. I am trying to decide on which platform/OS and tool to select. I am concerned with the size of the market available for my applications as well as the marketibility of the skills I will pick up. The apps I have in mind would work on both phones and pads. Some aspects of what I have in mind will play better on the bigger screens that will be available on pads. Here are the options I am considering: Apple iPhone/iPad using pure Apple SDK (Objective-C) Apple iPhone/iPad using Mono Touch (C#) Android using pure Android SDK (Java) Multiple platforms using something like Titanium to generate native apps from web technologies (HTML, CSS and Javascript) Multiple platforms using HTML5 web applications that run in the browser (HTML, CSS and Javascript). Which option would you choose? Do you have a different suggestion? What are the pros and cons?

  • How can I write a clean Repository without exposing IQueryable to the rest of my application?

    - by Simucal
    So, I've read all the Q&A's here on SO regarding the subject of whether or not to expose IQueryable to the rest of your project or not (see here, and here), and I've ultimately decided that I don't want to expose IQueryable to anything but my Model. Because IQueryable is tied to certain persistence implementations I don't like the idea of locking myself into this. Similarly, I'm not sure how good I feel about classes further down the call chain modifying the actual query that aren't in the repository. So, does anyone have any suggestions for how to write a clean and concise Repository without doing this? One problem I see, is my Repository will blow up from a ton of methods for various things I need to filter my query off of. Having a bunch of: IEnumerable GetProductsSinceDate(DateTime date); IEnumberable GetProductsByName(string name); IEnumberable GetProductsByID(int ID); If I was allowing IQueryable to be passed around I could easily have a generic repository that looked like: public interface IRepository<T> where T : class { T GetById(int id); IQueryable<T> GetAll(); void InsertOnSubmit(T entity); void DeleteOnSubmit(T entity); void SubmitChanges(); } However, if you aren't using IQueryable then methods like GetAll() aren't really practical since lazy evaluation won't be taking place down the line. I don't want to return 10,000 records only to use 10 of them later. What is the answer here? In Conery's MVC Storefront he created another layer called the "Service" layer which received IQueryable results from the respository and was responsible for applying various filters. Is this what I should do, or something similar? Have my repository return IQueryable but restrict access to it by hiding it behind a bunch of filter classes like GetProductByName, which will return a concrete type like IList or IEnumerable?

  • Model validation with enumerations

    - by Robert Koritnik
    I'm using DataAnnotations attributes to validate my model objects. My model class looks similar to this: public class MyModel { [Required] public string Title { get; set; } [Required] public List<User> Editors { get; set; } } public class User { public int Id { get; set; } [Required] public string FullName { get; set; } [Required] [DataType(DataType.Email)] public string Email { get; set; } } My controller action looks like: public ActionResult NewItem(MyModel data) { //... } User is presented with a view that has a form with: a text box with dummy name where users enter user's names. For each user they enter, there's a client script coupled with ajax that creates an <input type="hidden" name="data.Editors[0].Id" value="userId" /> for each user entered (enumeration index is therefore not always 0 as written here), so default model binder is able to consume and bind the form without any problems. a text box where users enter the title Since I'm using Asp.net MVC 2 RTM which does model validation instead of input validation I don't know how to avoid validation errors. The thing is I have to use BindAttribute on my controller action. I would have to either provide a white or a black list of properties. It's always a better practice to provide a white list. It's also more future proof. The problem My form works fine, but I get validation errors about user's FullName and Email properties since they are not provided. I also shouldn't feed them to the client (via ajax when user enters user data), because email is personal contact data and is not shared between users. If there was just a single user reference on MyModel I would write [Bind(Include = "Title, Editor.Id")] But I have an enumeration of them. How do I provide Bind white list to work with my model?

  • Starting out Silverlight 4 design

    - by Fermin
    I come from mainly a web development background (ASP.NET, ASP.NET MVC, XHTML, CSS etc) but have been tasked with creating/designing a Silverlight application. The application is utilising Bing Maps control for Silverlight, this will be contained in a user control and will be the 'main' screen in the system. There will be numerous other user controls on the form that will be used to choose/filter/sort/order the data on the map. I think of it like Visual Studio: the Bing Maps will be like the code editor window and the other controls will be like Solutions Explorer, Find Results etc. (although a lot less of them!) I have read up and I'm comfortable with the data side (RIA-Services) of the application. I've (kinda) got my head around databinding and using a view model to present data and keep the code behind file lite. What I do need some help on is UI design/navigation framework, specifically 2 aspects: How do I best implement a fluid design so that the various user controls which filter the map data can be resized/pinned/unpinned (for example, like the Solution Explorer in VS)? I made a test using a Grid with a GridSplitter control, is this the best way? Would it be best to create a Grid/Gridsplitter with Navigation Frames inside the grid to load the content? Since I have multiple user controls that basically use the same set of data, should I set the dataContext at the highest possible level (e.g. if using a grid with multiple frames, at the Grid level?). Any help, tips, links etc. will be very much appreciated!

  • codeigniter and OOP general question regarding calling functions, and the parent constuctor

    - by thrice801
    Ok so I have some gaps in my understanding of PHP OOP, classes and functions specifically, this whole constructor class deal. I use both Zend and CI but right now Im trying to figure this out in CI as it is less complicated. So all Im trying to do is understand how to call a function from a view page in code igniter. I understand that might go against MVC but Im working with an api and search results not from my database, so basically, I want to define a function in my class that I am able to call in one of my view pages.. and I keep getting "Fatal error: Call to undefined function functionname" error no matter what I try. I thought I just had to declare public function testing() { echo "testing testing 123; } but calling that from the view I get that error. Then I read something about having to go parent::Controller(); in the index of the class where the testing function also resides? But that didnt work either. Anyways, ya, can someone explain what I need to do in order to call the "testing()" function on one of my view pages? and clarification on the constructor class and what exactly parent::Controller() even does, would be much appreciated as well.

  • Front End Developer v/s PHP-MySQL Engineer

    - by user301943
    Hello, I want to decide which of this would be a more viable career option? I am ready to quit my current job and hence I am looking for new opportunity. Current job is maintainence and no more active development. My current role is of a PHP/MySQL Developer. I very well understand web-programming and am comfortable with RoR/Sinatra/Zend MVC/JQuery/JSON manipulation, etc. I understand MySQL InnoDB/MyISAM engine and how one differs from the other, etc. Basically, I could very well manage the deployment of a web-application end-to-end including configuration of Apache/Nginx servers, memcache,etc On the other hand, I am being offered a Sr.Front End Web developer that would require me to extensively write HTML/CSS crossbrowser/crossplatform compliant code. I very well understand XHTML/CSS/Box model etc. I would be working on Drupal for the management of websites. While I understand continuing to work on server-side technologies would always be a good career path, how would the role of Core front-end developer turn out to be? If I take this opportunity, will I eventually get a chance to focus onto UCD, HCI, Information Architect,etc. So are these kinda roles possible if I focus on front end development? No offenses to the Front end developers, just want to understand if this is something I want to gain a mastery over. I have 2 yrs of industry experience after graduating with a MS-Computer Science. Although, I have a CS degree, if I were to take uip serious front-end role; I could probably go back and take up some design/HCI/UI courses. Please advise.

  • ACL architechture for a Software As a service in Spring 3.0

    - by geoaxis
    I am making a software as a service using Spring 3.0 (Spring MVC, Spring Security, Spring Roo, Hibernate) I have to come up with a flexible access control list mechanism.I have three different kinds of users System (who can do any thing to the system, includes admin and internal daemons) Operations (who can add and delete users, organizations, and do maintenance work on behalf of users and organizations) End Users (they belong to one or more organization, for each organization, the user can have one or more roles, like being organization admin, or organization read-only member) (role like orgadmin can also add users for that organization) Now my question is, how should i model the entity of User? If I just take the End User, it can belong to one or more organizations, so each user can contain a set of references to its organizations. But how do we model the users role for each organization, So for example User UX belongs to organizations og1, og2 and og3, and for og1 he is both orgadmin, and org-read-only-user, where as for og2 he is only orgadmin and for og3 he is only org-read-only-user I have the possibility of making each user belong to one organization alone, but that's making the system bounded and I don't like that idea (although i would still satisfy the requirement) If you have a better extensible ACL architecture, please suggest it. Since its a software as a service, one would expect that alot of different organizations would be part if the same system. I had one concern that it is not a good idea to keep og1 and og2 data on the same DB (if og1 decides to spawn a 100 reports on the system, og2 should not suffer) But that is some thing advanced for now and is not directly related to ACL but to the physical distribution of data and setup of services based on those ACLs This is a community Wiki question, please correct any thing which you wish to do so. Thanks

  • Debugging Key-Value-Observing overflow.

    - by Paperflyer
    I wrote an audio player. Recently I started refactored some of the communication flow to make it fully MVC-compliant. Now it crashes, which in itself is not surprising. However, it crashes after a few seconds inside the Cocoa key-value-observing routines with a HUGE stack trace of recursive calls to NSKeyValueNotifyObserver. Obviously, it is recursively observing a value and thus overflowing the NSArray that holds pending notifications. According to the stack trace, the program loops from observeValueForKeyPath to setMyValue and back. Here is the according code: - (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context { if ([keyPath isEqual:@"myValue"] && object == myModel && [self myValue] != [myModel myValue]) { [self setMyValue:[myModel myValue]; } } and - (void)setMyValue:(float)value { myValue = value; [myModel setMyValue:value]; } myModel changes myValue every 0.05 seconds and if I log the calls to these two functions, they get called only every 0.05 seconds just as they should be, so this is working properly. The stack trace looks like this: -[MyDocument observeValueForKeyPath:ofObject:change:context:] NSKeyValueNotifyObserver NSKeyValueDidChange -[NSObject(NSKeyValueObserverNotification) didChangeValueForKey:] -[MyDocument setMyValue:] _NSSetFloatValueAndNotify …repeated some ~8k times until crash Do you have any idea why I could still be spamming the KVO queue?

  • JSP or .ascx equivalent for Scala?

    - by Daniel Worthington
    I'm working on a small MVC "framework" (it's really very small) in Scala. I'd like to be able to write my view files as Scala code so I can get lots of help from the compiler. Pre-compiling is great, but what I really want is a way to have the servlet container automatically compile certain files (my view files) on request so I don't have to shut down Jetty and compile all my source files at once, then start it up again just to see small changes to my HTML. I do this a lot with .ascx files in .NET (the file will contain just one scriptlet tag with a bunch of C# code inside which writes out markup using an XmlWriter) and I love this workflow. You just make changes and then refresh your browser, but it's still getting compiled! I don't have a lot of experience with Java, but it seems possible to do this with JSP as well. I'm wondering if this sort of thing is possible in Scala. I have looked into building this myself (see more info here: http://www.nabble.com/Compiler-API-td12050645.html) but I would rather use something else if it's out there.

  • Spell checker software

    - by Naren
    Hello Guys, I have been assigned a task to find a decent spell checker (UK English) preferably the free one for a project that we are doing. I have looked at Google AJAX API for this. The project contains some young person's (kids less than 18 years old) data which shouldn't allow exposing or storing outside the application boundaries. Google logs the data for research purpose that means Google owns the data whatever we send over the wire through Google API. Is this right? I fired an email to Google regarding the privacy of data and storage but they haven't come back. If you have some knowledge regarding this please share with me. At this point our servers might not have access to external entities that means we might not be able to use Web API for this over the wire. But it may change in the future. That means I have to find out some spell checker alternatives that can sit in our environment and do the job or an external APIs. Would you mind share your findings and knowledge in this regard. I would prefer free services but never know if you have some cracking spell checker for a few quid’s then I don't mind recommending to the project board. Technology using ASP.NET 3.5/4.0, MVC, jQuery, SQL Sever 2008 etc Cheers, Naren

  • Feasibility of using Silverlight for web and windows client with common code base for data intensive

    - by Kabeer
    Hello. Recently in a conversation, someone suggested me to make use of Silverlight if I am targeting a web client and a windows client for the same application. This will cut down my effort for supporting the contrast in both presentation layers. Mine is a product, that will be deployed in enterprises. Both web and windows clients are desirable. With the above context, I have few queries: Is it advisable to adopt the recommended approach and whether this approach is becoming a trend? Besides, some configuration & deployment tweaking, will this significantly reduce effort on the presentation layer? Is there a possibility that my future prospects (for this product) will resist Silverlight footprint? Will I be able to make use of the ASP.Net MVC pattern? Will there be any performance implication for the web client? Will Silverlight support incremental load of controls? If my back-end includes SSRS, will I be able to harness all its front end features with Silverlight? Will I be able to support additional devices with same code base in future? Mine is a very data intensive application from both, data entry and reporting perspective. Is it advisable to use 3rd party controls (like Telerik) for improved user experience and developer productivity? Are their any professional quality open source Silverlight controls (library) available? Further, I seek information of best practices in the context I shared above.

  • How to enable OutputCache with an IHttpHandler

    - by Joseph Kingry
    I have an IHttpHandler that I would like to hook into the OutputCache support so I can offload cached data to the IIS kernel. I know MVC must do this somehow, I found this in OutputCacheAttribute: public override void OnResultExecuting(ResultExecutingContext filterContext) { if (filterContext == null) { throw new ArgumentNullException("filterContext"); } // we need to call ProcessRequest() since there's no other way to set the Page.Response intrinsic OutputCachedPage page = new OutputCachedPage(_cacheSettings); page.ProcessRequest(HttpContext.Current); } private sealed class OutputCachedPage : Page { private OutputCacheParameters _cacheSettings; public OutputCachedPage(OutputCacheParameters cacheSettings) { // Tracing requires Page IDs to be unique. ID = Guid.NewGuid().ToString(); _cacheSettings = cacheSettings; } protected override void FrameworkInitialize() { // when you put the <%@ OutputCache %> directive on a page, the generated code calls InitOutputCache() from here base.FrameworkInitialize(); InitOutputCache(_cacheSettings); } } But not sure how to apply this to an IHttpHandler. Tried something like this, but of course this doesn't work: public class CacheTest : IHttpHandler { public void ProcessRequest(HttpContext context) { OutputCacheParameters p = new OutputCacheParameters { Duration = 3600, Enabled = true, VaryByParam = "none", Location = OutputCacheLocation.Server }; OutputCachedPage page = new OutputCachedPage(p); page.ProcessRequest(context); context.Response.ContentType = "text/plain"; context.Response.Write(DateTime.Now.ToString()); context.Response.End(); } public bool IsReusable { get { return true; } } }

  • Choosing a Java Web Framework now?

    - by hbagchi
    we are in the planning stage of migrating a large website which is built on a custom developed mvc framework to a java based web framework which provides built-in support for ajax, rich media content, mashup, templates based layout, validation, maximum html/java code separation. Grails looked like a good choice, however, we do not want to use a scripting language. We want to continue using java. Template based layout is a primary concern as we intend to use this web application with multiple web sites with similar functionality but radically different look and feel. Is portal based solution a good fit to this problem? Any insights on using "Spring Roo" or "Play" will be very helpful. I did find similar posts like this, but it is more than a year old. Things have surely changed in the mean time! EDIT 1: Thanks for the great answers! This site is turning to be the best single source for in-the-trenches programmer info. However, I was expecting more info on using a portal-cms duo. Jahia looks goods. Anything similar?
