  • Persisting Session Between Different Browser Instances

    - by imran_ku07
        Introduction:          By default inproc session's identifier cookie is saved in browser memory. This cookie is known as non persistent cookie identifier. This simply means that if the user closes his browser then the cookie is immediately removed. On the other hand cookies which stored on the user’s hard drive and can be reused for later visits are called persistent cookies. Persistent cookies are less used than nonpersistent cookies because of security. Simply because nonpersistent cookies makes session hijacking attacks more difficult and more limited. If you are using shared computer then there are lot of chances that your persistent session will be used by other shared members. However this is not always the case, lot of users desired that their session will remain persisted even they open two instances of same browser or when they close and open a new browser. So in this article i will provide a very simple way to persist your session even the browser is closed.   Description:          Let's create a simple ASP.NET Web Application. In this article i will use Web Form but it also works in MVC. Open Default.aspx.cs and add the following code in Page_Load.    protected void Page_Load(object sender, EventArgs e)        {            if (Session["Message"] != null)                Response.Write(Session["Message"].ToString());            Session["Message"] = "Hello, Imran";        }          This page simply shows a message if a session exist previously and set the session.          Now just run the application, you will just see an empty page on first try. After refreshing the page you will see the Message "Hello, Imran". Now just close the browser and reopen it or just open another browser instance, you will get the exactly same behavior when you run your application first time . Why the session is not persisted between browser instances. The simple reason is non persistent session cookie identifier. The session cookie identifier is not shared between browser instances. Now let's make it persistent.          To make your application share session between different browser instances just add the following code in global.asax.    protected void Application_PostMapRequestHandler(object sender, EventArgs e)           {               if (Request.Cookies["ASP.NET_SessionIdTemp"] != null)               {                   if (Request.Cookies["ASP.NET_SessionId"] == null)                       Request.Cookies.Add(new HttpCookie("ASP.NET_SessionId", Request.Cookies["ASP.NET_SessionIdTemp"].Value));                   else                       Request.Cookies["ASP.NET_SessionId"].Value = Request.Cookies["ASP.NET_SessionIdTemp"].Value;               }           }          protected void Application_PostRequestHandlerExecute(object sender, EventArgs e)        {             HttpCookie cookie = new HttpCookie("ASP.NET_SessionIdTemp", Session.SessionID);               cookie.Expires = DateTime.Now.AddMinutes(Session.Timeout);               Response.Cookies.Add(cookie);         }          This code simply state that during Application_PostRequestHandlerExecute(which is executed after HttpHandler) just add a persistent cookie ASP.NET_SessionIdTemp which contains the value of current user SessionID and sets the timeout to current user session timeout.          In Application_PostMapRequestHandler(which is executed just before th session is restored) we just check whether the Request cookie contains ASP.NET_SessionIdTemp. If yes then just add or update ASP.NET_SessionId cookie with ASP.NET_SessionIdTemp. So when a new browser instance is open, then a check will made that if ASP.NET_SessionIdTemp exist then simply add or update ASP.NET_SessionId cookie with ASP.NET_SessionIdTemp.          So run your application again, you will get the last closed browser session(if it is not expired).   Summary:          Persistence session is great way to increase the user usability. But always beware the security before doing this. However there are some cases in which you might need persistence session. In this article i just go through how to do this simply. So hopefully you will again enjoy this simple article too.

  • Solving “The Select operation is not supported by .. unless the SelectMethod is specified.”

    - by anas
    In most cases, You will get that error when you are using a data source control(like ObjectDataSource) without setting it’s SelectMethod as data source for the DetailsView control. If you want to display one record in the detailsView control to allow the user to edit it, then you should set the SelectMethod for the DataSource control,otherwise the detailsView control will not be able to get the record from the underlying datasource. But what if you are only using the DetailsView for only inserting...(read more)

  • Using some kind of version control when working alone and with small projects?

    - by Roflcoptr
    Very often I'm working on small projects only for myself. I'm working on one machine, but recently I thought about using some kind of version control nevertheless. This would have some benefits as for example: I don't have to care anymore for local backup Mistakes can easily made undone History can be maintained But on the other hand it has also some drawbacks like for example: Additional resources required Time to setup, get used to it, etc. From your experience, is it a good thing to use revision control when your working alone?

  • Is it dangerous for me to give some of my Model classes Control-like methods?

    - by Pureferret
    In my personal project I have tried to stick to MVC, but I've also been made aware that sticking to MVC too tightly can be a bad thing as it makes writing awkward and forces the flow of the program in odd ways (i.e. some simple functions can be performed by something that normally wouldn't, and avoid MVC related overheads). So I'm beginning to feel justified in this compromise: I have some 'manager programs' that 'own' data and have some way to manipulate it, as such I think they'd count as both part of the model, and part of the control, and to me this feels more natural than keepingthem separate. For instance: One of my Managers is the PlayerCharacterManager that has these methods: void buySkill(PlayerCharacter playerCharacter, Skill skill); void changeName(); void changeRole(); void restatCharacter(); void addCharacterToGame(); void createNewCharacter(); PlayerCharacter getPlayerCharacter(); List<PlayerCharacter> getPlayersCharacter(Player player); List<PlayerCharacter> getAllCharacters(); I hope the mothod names are transparent enough that they don't all need explaining. I've called it a manager because it will help manage all of the PlayerCharacter 'model' objects the code creates, and create and keep a map of these. I may also get it to store other information in the future. I plan to have another two similar classes for this sort of control, but I will orchestrate when and how this happens, and what to do with the returned data via a pure controller class. This splitting up control between informed managers and the controller, as opposed to operating just through a controller seems like it will simplify my code and make it flow more. My question is, is this a dangerous choice, in terms of making the code harder to follow/test/fix? Is this somethign established as good or bad or neutral? I oculdn't find anything similar except the idea of Actors but that's not quite why I'm trying to do. Edit: Perhaps an example is needed; I'm using the Controller to update the view and access the data, so when I click the 'Add new character to a player button' it'll call methods in the controller that then go and tell the PlayerCharacterManager class to create a new character instance, it'll call the PlayerManager class to add that new character to the player-character map, and then it'll add this information to the database, and tell the view to update any GUIs effected. That is the sort of 'control sequence' I'm hoping to create with these manager classes.

  • What is the best .NET web development framework?

    - by tjjjohnson
    I'm looking for a framework to simplify the creation of a website with social networking features and plenty of custom functionality. I'm quite keen to use an ORM like nHibernate or similar for data access. Would DotNetNuke be a good choice? Or are there other options which are better. Added: I'm quite keen not to have to reinvent the wheel for the social network features like secure login, open id, friends etc.

  • Which datagrid to use for ASP.NET MVC2 project?

    - by Nick
    Hi, I am developing a commercial MVC2 app that requires a grid that has callback update in some form to support 10,000+ rows. It should also support relatively rich content (icons, multiline descriptions etc). Although it requires the usual paging/scrolling/sorting features it does not need support for grouping. So nothing that special. The commercial grids I looked at were Component Art (http://www.componentart.com/products/aspnetmvc/datagrid/) and Telerik (http://www.telerik.com/products/aspnet-mvc/grid.aspx) which both look pretty good but may be a little OTT for what I need. They are also $800 and $999 respectively (1 developer). I've also looked at jqGrid (http://www.trirand.net/download.aspx) and the grid from MvcContrib. These appear ok but for a commercial app I am concerned that these may be risky options - though could be wrong there. I'd really appreciate any views/exprience on either the above grids or perhaps you can suggest a better option/approach. FYI I am using EF4 and C#. Cheers

  • File extensions and MIME Types in .NET

    - by Marc Climent
    I want to get a MIME Content-Type from a given extension (preferably without accessing the physical file). I have seen some questions about this and the methods described to perform this can be resumed in: Use registry information. Use urlmon.dll's FindMimeFromData. Use IIS information. Roll your own MIME mapping function. Based on this table, for example. I've been using no.1 for some time but I realized that the information provided by the registry is not consistent and depends on the software installed on the machine. Some extensions, like .zip don't use to have a Content-Type specified. Solution no.2 forces me to have the file on disk in order to read the first bytes, which is something slow but may get good results. The third method is based on Directory Services and all that stuff, which is something I don't like much because I have to add COM references and I'm not sure it's consistent between IIS6 and IIS7. Also, I don't know the performance of this method. Finally, I didn't want to use my own table but at the end seems the best option if I want a decent performance and consistency of the results between platforms (even Mono). Do you think there's a better option than using my own table or one of other described methods are better? What's your experience?

  • What would cause ANY .NET application to crash immediately... except a project I create and Debug in

    - by blak3r
    My software recently got deployed to a customer who said that the application was crashing immediately after it started. After some initial debugging, the customer provided me remote access to one of the computers which was unable to run the application. I found that the crash wasn't specific to my application. Any application which depended on the .NET framework crashed immediately. Conveniently, Visual Studio 2008 was installed so I created a quick hello world application on it and clicked Debug. The application worked fine. But, then when I tried to execute the generated binaries in the /bin/Debug/HelloWorld.exe directory outside of visual studio it crashed. List of things i've tried (UPDATED): I checked that "Everyone" has Read&Execute permissions for c:\Windows. To test that the problem was with the .NET Framework (and not my application), I attempted to download Paint .NET on to the computers. The setup frontend crashed in the same manner. Performed a repair of the .NET framework as outlined in http://support.microsoft.com/kb/908077 (Boy was this fun and time consuming). No luck. Installed .NET 3.5 SP1 (before it just had .NET 3.5) Note: my application targets 2.0 so I did this more as a long shot... but i learned in the process that .NET 3.5 SP1 also updates the underlying frameworks. Ran Aaron Stebner's .NET Setup Verification Tool. This tool indicated that .NET was successfully installed. (I forget if i checked all the versions but at least 2.0 worked). Tested some mini hello world applications which were targeted for .NET 2.0 and .NET 3.5 and both crashed in the same way. Tried launching .NET apps via windbg cmd line. Doing this did allow me invoke my simple hello world applications. So, simple .NET hello world works when invoked by windbg or by launching via debug in visual studio... but doesn't if i try to execute it standalone. I created a dump file using WinDbg. It wasn't all that revealing to me.

  • Is it possible to access ASP.NET anonymous profile for a logged in user?

    - by Simon_Weaver
    The ASP.NET membership supports anonymous users and logged in users. If you call FormsAuthentication.SetAuthCookie(userName, createPersistentCookie); with a true for createPersistentCookie then the user will be logged in automatically when they revisit your site - even after closing the browser. If you don't enable this 'remember me' feature, then the anonymous cookie will still be around when the user visits your site again. I'd like to do be able to store information in the user's anonymous profile when they are logged in. i.e. I don't want them to remain authenticated on the site if they go away and come back, but I'd still like be able to track certain things - like perhaps a visitCount property in the anonymous profile. Is there any way to access a user's anonymous profile when they are authenticated. The two cookies exist so it should be possible. I don't want to reinvent half the wheel! ps. I realize that tracking is skewed if multiple users use the system but thats fine.

  • MVC.NET UpdateModel doesn't update inherited public properties??

    - by mrjoltcola
    I refactored some common properties into a base class and immediately my model updates started failing. UpdateModel() and TryUpdateModel() do not seem to update inherited public properties. I cannot find detailed info on MSDN nor Google as to the rules or semantics of these methods. The docs are terse (http://msdn.microsoft.com/en-us/library/dd470933.aspx), simply stating: Updates the specified model instance using values from the controller's current value provider. Well that leads us to believe it is as simple as that. It makes no mention of limitations with inheritance. My assumption is the methods are reflecting on the top class only, ignoring base properties, but this seems to be an ugly shortcoming, if so.

  • ASP.NET MVC, areas, routing and a controller factory.

    - by Kieron
    Hi, I've an interesting problem with some routing with an ASP.NET MVC app. I'm building a CMS and I've got a catch-all handler that takes the URL and checks to see if there's some matching content in a database. If so, it displays it, otherwise we get a 404. Now I've got all that working with some test data, I moved on to write a quick admin system. I thought I'd use some of the new Area functionality baked into MVC 2, so I've created an area called Admin with a controller called Home. Now however I have a problem of the default HomeController in the Admin Area is being returned when requesting the application root path. The problem is that there is no other HomeController for the 'root' application (the one hosting all of the areas), instead the root would be redirected to the my catch-all handler and populated from the database. So now the controller factory is returning the best matching controller, which it thinks is the admin area one, what I really need is for it to not match it at all - as it did previously. Apart from renaming the Admin HomeController to something else, is there another solution?

  • How do I repopulate the view model in ASP.NET MVC 2 after a validation error?

    - by Keltex
    I'm using ASP.NET MVC 2 and here's the issue. My View Model looks something like this. It includes some fields which are edited by the user and others which are used for display purposes. Here's a simple version public class MyModel { public decimal Price { get; set; } // for view purpose only [Required(ErrorMessage="Name Required")] public string Name { get; set; } } The controller looks something like this: public ActionResult Start(MyModel rec) { if (ModelState.IsValid) { Repository.SaveModel(rec); return RedirectToAction("NextPage"); } else { // validation error return View(rec); } } The issue is when there's a validation error and I call View(rec), I'm not sure the best way to populate my view model with the values that are displayed only. The old way of doing it, where I pass in a form collection, I would do something like this: public ActionResult Start(FormCollection collection) { var rec = Repository.LoadModel(); UpdateModel(rec); if (ModelState.IsValid) { Repository.SaveModel(rec); return RedirectToAction("NextPage"); } else { // validation error return View(rec); } } But doing this, I get an error on UpdateModel(rec): The model of type 'MyModel' could not be updated. Any ideas?

  • Constructing an object and calling a method without assignment in VB.Net

    - by mdryden
    I'm not entirely sure what to call what C# does, so I haven't had any luck searching for the VB.Net equivalent syntax (if it exists, which I suspect it probably doesn't). In c#, you can do this: public void DoSomething() { new MyHelper().DoIt(); // works just fine } But as far as I can tell, in VB.Net, you must assign the helper object to a local variable or you just get a syntax error: Public Sub DoSomething() New MyHelper().DoIt() ' won't compile End Sub Just one of those curiosity things I run into from day to day working on mixed language projects - often there is a VB.Net equivalent which uses less than obvious syntax. Anyone?

  • LazyList<T> vs System.Lazy<List<T>> in ASP.NET MVC 2?

    - by FreshCode
    In Rob Conery's Storefront series, Rob makes extensive use of the LazyList<..> construct to pull data from IQueryables. How does this differ from the System.Lazy<...> construct now available in .NET 4.0 (and perhaps earlier)? More depth based on DoctaJones' great answer: Would you recommend one over the other if I wanted to operate on IQueryable as a List<T>? I'm assuming that since Lazy<T> is in the framework now, it is a safer bet for future support and maintainability? If I want to use a strong type instead of an anonymous (var) type would the following statements be functionally equivalent? Lazy<List<Products>> Products = new Lazy<List<Product>>(); LazyList<Product> = new LazyList<Product>();

  • Rewriting VB.NET Lambda experession as a C# statement

    - by ChadD
    I downgraded my app from version 4 of the framework to version 4 and now I want to implement this VB.NET lambda function statement (which works on 3.5) Dim colLambda As ColumnItemValueAccessor = Function(rowItem As Object) General_ItemValueAccessor(rowItem, colName) and rewrite it in C#. This was my attempt: ColumnItemValueAccessor colLambda = (object rowItem) => General_ItemValueAccessor(rowItem, colName); When I did this, I get the following error: Error 14 One or more types required to compile a dynamic expression cannot be found. Are you missing references to Microsoft.CSharp.dll and System.Core.dll? C:\Source\DotNet\SqlSmoke\SqlSmoke\UserControls\ScriptUserControl.cs 84 73 SqlSmoke However, when I downgraded the app from version 4.0 of the framework to 3.5 (because our users only hae 3.5 and don't have rights to install 4.0). when I did this, the reference to "Microsoft.CSharp" was broken. Can I rewrite the VB.NET command in C# using syntax that is valid in C# 3.5 as I was able to in VB.NET? What would the syntax be?

They can do this: <%= javascript_include_tag "all_min" %> ... and I'm stuck doing this: <script src="/public/javascript/jquery/jquery.js" type="text/javascript"></script> <script src="/public/javascript/jquery/jquery.tablesorter.js" type="text/javascript"></script> <script src="/public/javascript/jquery/jquery.tablehover.pack.js" type="text/javascript"></script> <script src="/public/javascript/jquery/jquery.validate.js" type="text/javascript"></script> <script src="/public/javascript/jquery/jquery.form.js" type="text/javascript"></script> <script src="/public/javascript/jquery/application.js" type="text/javascript"></script> Are there any libraries to compress, gzip and combine multiple js files? How about CSS files?
