  • How does this Singleton Web Class persists session data, even though session is not updated in the p

    - by Micah Burnett
    Ok, I've got this singleton-like web class which uses session to maintain state. I initially thought I was going to have to manipulate the session variables on each "set" so that the new values were updated in the session. However I tried using it as-is, and somehow, it remembers state. For example, if run this code on one page: UserContext.Current.User.FirstName = "Micah"; And run this code in a different browser tab, FirstName is displayed correctly: Response.Write(UserContext.Current.User.FirstName); Can someone tell me (prove) how this data is getting persisted in the session? Here is the class: using System; using System.Collections.Generic; using System.Linq; using System.Web; public class UserContext { private UserContext() { } public static UserContext Current { get { if (System.Web.HttpContext.Current.Session["UserContext"] == null) { UserContext uc = new UserContext(); uc.User = new User(); System.Web.HttpContext.Current.Session["UserContext"] = uc; } return (UserContext)System.Web.HttpContext.Current.Session["UserContext"]; } } private string HospitalField; public string Hospital { get { return HospitalField; } set { HospitalField = value; ContractField = null; ModelType = null; } } private string ContractField; public string Contract { get { return ContractField; } set { ContractField = value; ModelType = string.Empty; } } private string ModelTypeField; public string ModelType { get { return ModelTypeField; } set { ModelTypeField = value; } } private User UserField; public User User { get { return UserField; } set { UserField = value; } } public void DoSomething() { } } public class User { public int UserId { get; set; } public string FirstName { get; set; } }

  • Shutting down a windows service that has threads

    - by Dave
    I have a windows service written in .NET 3.5 (c#) with a System.Threading.Timer that spawns several Threads in each callback. These are just normal threads (no Thread Pool) and I've set the IsBackground = true on each thread since I'm only going to be running managed code. When a user stops the service, what happens to all the threads? Do they die gracefully? I don't have any code that manages the threads via calling join or abort. Is it correct to assume the IsBackground = true is enough to assume the threads will be disposed and stopped when a user stops the service? What exactly happens when someone stops a windows service via the Service Manager GUI? Does it kill the process after it fires the OnStop event? This would actually be acceptable for me because I've built a separate mechanism that allows a user know for sure there are no threads before they stop the service. This is done via 2 WCF methods exposed from a ServiceHost that runs inside the Windows Service. There's one method to stop spawning new threads and another method to query how many running threads there are left. I'm just curious what happens if they skip those steps and just stop the service... It seems the IsBackground helps achieve this:

  • What is a Web Framework ? How does it compare with LAMP

    - by Nishant
    I started web development in LAMP/WAMP and it was logical to me . There is a Web Server program called Apache which does the networking part of setting up a service on port 80 ( common port ) . If the request is regular HTML it uses the HTTP headers to transport files .And if the request for the file is a PHP one , it has a mod_php with which Apache invokes the PHP interpreter to process the file and it gives back HTML which is again transferred as usual HTML . Now the question is what is a Web Framework ? I came across Python based website creation and there is Flask . What is a flask , how does it compare with LAMP . Further are DJango / Ruby on Rails different from flask ? Can someone answer me and also give some good places to read on these .Thanks for your answers in advance . Further is things like LAMP slower than the common FRAMEWORKS because they claimn easy deplyment fo web apps .

  • How realistic/easy is it to host our own web servers?

    - by morpheous
    It is increasingly looking like we will need to host our own servers, because we need modems physically attached to the server machines. I (think) we will need a T1 line to our office for starters. Dont know what else is involved other than the obvious redundancy and failover requirements. My questions are: Do we really have to do it our selves or can we find a service that allows the modems to be remote as well? If we have to host the servers ourselves, what are the steps (technical and operational) required?

  • JavaScript method to write to Microsoft Visual Web Developer Debugger?

    - by Josh
    I generally test my web apps with Firefox and use Firebug. I love Firebug. But when I'm testing JavaScript code in IE I use the debugger in Microsoft's Visual Web Developer 2008 Express Edition. I would love to have an equivalent to Firebug's console.log methods which would allow me to log messages to Visual Web Developer. Any way to log messages to the error list/messages list/output pane using JavaScript?

  • Web service performing asynchronous call

    - by kornelijepetak
    I have a webservice method FetchNumber() that fetches a number from a database and then returns it to the caller. But just before it returns the number to the caller, it needs to send this number to another service so instantiates and runs the BackgroundWorker whose job is to send this number to another service. public class FetchingNumberService : System.Web.Services.WebService { [WebMethod] public int FetchNumber() { int value = Database.GetNumber(); AsyncUpdateNumber async = new AsyncUpdateNumber(value); return value; } } public class AsyncUpdateNumber { public AsyncUpdateNumber(int number) { sendingNumber = number; worker = new BackgroundWorker(); worker.DoWork += asynchronousCall; worker.RunWorkerAsync(); } private void asynchronousCall(object sender, DoWorkEventArgs e) { // Sending a number to a service (which is Synchronous) here } private int sendingNumber; private BackgroundWorker worker; } I don't want to block the web service (FetchNumber()) while sending this number to another service, because it can take a long time and the caller does not care about sending the number to another service. Caller expects this to return as soon as possible. FetchNumber() makes the background worker and runs it, then finishes (while worker is running in the background thread). I don't need any progress report or return value from the background worker. It's more of a fire-and-forget concept. My question is this. Since the web service object is instantiated per method call, what happens when the called method (FetchNumber() in this case) is finished, while the background worker it instatiated and ran is still running? What happens to the background thread? When does GC collect the service object? Does this prevent the background thread from executing correctly to the end? Are there any other side-effects on the background thread? Thanks for any input.

  • Clean install of IIS 6 on Windows Server 2003 ignoring 'web.config'?

    - by Vario
    Hi, Any help with this would be really appreciated! As the title suggests, I'm running a brand new install of Windows Server 2003 and IIS 6 and I'm basically attempting to mirror a live web server onto a new internal development server, which runs the same setup. It's an ASP.NET site that relies heavily on URL rewriting (using Intelligencia). ASP.NET is set to run on v2.0.50727 on both servers. I've tried intentionally introduce syntax errors into the web.config and it just appears to be ignoring them completely, so given IIS 6 doesn't read the web.config, the rest of the site doesn't work at all (I get a 404 error, as a 'Default.aspx' doesn't exist since the web.config handles the default page rewriting). Having looked at the Application Mapping, '.config' files are set to use the default 'c:\windows\microsoft.net\framework\v2.0.50727\aspnet_isapi.dll' which exists. Is there anything else I may be missing? Thanks in advance.

  • Problem with impersonating a specific user in WCF service

    - by aJ
    I am having a WCF service hosted in IIS on WindowsServer 2008. This service needs to write to a shared folder present on another machine(Windows XP). The shared folder has write permissions for a particular user say "X" which is present on both the machines .i.e on the server where the service is running as well as the machine where the shared folder is present. The service runs under the NETWORK SERVICE account. For the service to access the shared folder I have added code to impersonate the user "X"in the service so that it gets the permission to write to the shared folder. Since I want to impersonate user "X" only when I run a particular section of code I have used the sample code. Even after the impersonation the service fails to write to the shared folder sometimes. It works sporadically. Whereas if I add tag in the Web.config file it works perfectly fine. <identity impersonate="true" userName="accountname" password="password" /> But the above is not desirable since it impersonates a specific user for all the requests. What I need is to impersonate a specific user only when I run a particular section of code. Also, the impersonation code works absolutely fine when the shared folder is present on another WindowsServer 2008. Could anyone give me ideas on what's going wrong here.

  • Anyone NOT using a Web Framework? Why?

    - by tom
    I'm well aware of the many reasons to use a web framework. I'm just wondering whether anyone out there is using absolutely no web framework whatsoever to develop their web projects. I would really love to know the reason(s) why you're not using a web framework. For the sake of this discussion, your programming language of choice does not matter. Some possibilities for discussion: You don't hide behind an ORM. You don't rely on any sort of templating system. You think MVC is a really nice TLA but lacks an essential vowel or two. No need for any additional javascript framework tomfoolery. You just write as much code as possible in your native programming language(s). Summary of reasons thus far: Language learning opportunities. Specific performance reasons (write-intensive transaction processing). Seeking more nuanced control over your data and applications (less abstraction). You're building your own framework! Prove to yourself that you can succeed (or fail) just like the big framework-building gurus. Integration issues with unpopular/legacy technologies (exotic databases or protocols come to mind). Big company, lots of code, no talent nor buy-in present to move to a web framework. Some frameworks really lock you in and cannot perpetually grow along with your needs. These few black sheep don't make it easy to jump outside of the framework, write some custom code, and easily jump back in. When you finally escape the asylum, you'll never look back.

  • Model View Presenter plus ASP.NET Web Service; where does the asmx live?

    - by Dirk
    I've been slowly transitioning from a traditional web forms architecture to the MVP pattern (Passive View). So far, it's been fairly easy to implement b/c the views I've dealt with have all employed a classic PostBack model. However, I've come across my first view that will refresh portions of itself via web services. I can't grok where the web service should live (Presenter I think) or how to expose that asmx end point to my View while still maintaining the clean separation of concerns/testability that MVP affords me. I've searched far and wide for some examples on how this might be implemented and have come up with nothing. Please help!

  • Are self-described / auto-descriptive services loosely or tightly coupled in a SOA architecture ?

    - by snowflake
    I consider a self-described / auto-descriptive service as a good thing in a SOA architecture, since (almost) everything you know to call the service is present in the service contract (such a WSDL). Sample of a non self-described service for me is Facebook Query Language (FQL http://wiki.developers.facebook.com/index.php/FQL), or any web service exchanging XML flow in a one String parameter for then parsing XML and performing treatments. Last ones seem further more technically decoupled, since technically you can switch implementations without technical impact on the caller, handling compatibility between implementations/versions at a business level. On the other side, having no strong interface (diluted into the service and its version), make the service tightly coupled to the existing implementation (more difficulty to interchange the service and to ensure perfect compatibility). This question is related to http://stackoverflow.com/questions/2503071/how-to-implement-loose-coupling-with-a-soa-architecture So, are self-described / auto-descriptive services loosely or tightly coupled in a SOA architecture ? What are the impacts regarding ESBs ? Any pointer will be appreciated.

  • Web services or shared database for (game) server communication?

    - by jaaronfarr
    We have 2 server clusters: the first is made up of typical web applications backed by SQL databases. The second are highly optimized multiplayer game servers which keep all data in memory. Both clusters communicate with clients via HTTP (Ajax with JSON). There are a few cases in which we need to share data between the two server types, for example, reporting back and storing the results of a game (should ultimately end up in the database). We're considering several approaches for inter-server communication: Just share the MySQL databases between clusters (introduce SQL to the game servers) Sharing data in a distributed key-value store like Memcache, Redis, etc. Use an RPC technology like Google ProtoBufs or Apache Thrift Using RESTful web services (the game server would POST back to the web servers, for example) At the moment, we're leaning towards web services or just sharing the database. Sharing the database seems easy, but we're concerned this adds extra memory and a new dependency into the game servers. Web services provide good separation of concerns and fit with the existing Ajax we use, but add complexity, overhead and many more ways for communication to fail. Are there any other good reasons not to use one or the other approach? Which would be easier to scale?

  • How do I refer to a client_deploy.wsdd file that's in WEB-INF?

    - by Paul
    A basic question, but I can't seem to find the answer. I have an Axis-generated web service that also calls another web service (for which the stubs are also generated with Axis). It's deployed in weblogic 9.2 That called web service requires authentication. I've googled for the code to set up authentication. It requires that I set up a client_deploy.wsdd file which I've done, and added it to WEB-INF. I need to specify this flle to Axis. There seem to be several ways of doing this, including System.setProperty("axis.ClientConfigFile", "client_deploy.wsdd") or EngineConfiguration config = new FileProvider("client_deploy.wsdd"); but these aren't working for me. Is the issue the path for the client_deploy.wsdd file? How do I refer to a file that's at the top level of the WEB-INF directory? Googling tells me how to access it as a stream, but I don't want that, I need to pass a file name to these functions... Please point out the obvious that I have missed

  • I need to create a web service using .NET-- where should I start?

    Hi All I am trying to implement a feature. But I've never had anything to do with "Web Services" before, other than using them. I have a desktop application, and I want that application to be able to sort of "post" some information (i.e. email address, username, user-selected options (just plain text) etc) to an application or "web service" on my ASP.NET web server. Can somebody please guide me in the right direction? How would I accomplish this? Thank you :) Jason

  • Are There Any Other Web Programming Languages That Can Be Used Without A Framework Aside From PHP?

    - by Ygam
    Python needs a framework, so does Java (for the web). I don't know much about Ruby or Coldfusion. But is there another language out there for the web that can stand alone as it is without a need for a framework or without strict adherence to a design pattern (MVC and the likes) aside from PHP? BTW, the statement that Python and Java needs a framework to work with the web came purely from my readings on articles and books; I might be mistaken.

  • How to make web service methods return string value in lines format?

    - by Born To Learn
    How to make web service methods return string value in lines format? My web service method looks like this [WebMethod] public string GetSomeLines() { System.Text.StringBuilder builder = new StringBuilder(); builder.AppendLine("Line1."); builder.AppendLine("Line2."); builder.AppendLine("Line3."); return builder.ToString(); } But when I get the result from web browser or from delphi/c# consumer it will be like this: Line1. Line2. Line3. While I expect to see: Line1. Line2. Line3. I know may be returning a StringBuilder or String Array is an option here but I want to know if there is a way to make this with string result. Thanks for your help.
