  • Dependency Injection -Colloquial explanation

    - by nettguy
    Recently I was asked to express the DI in colloquial explanation. I answered : 1) I am going to a hotel.I ordered food.The hotel management asks me to clean the plates and clean the tables.So here i am a client,I am responsible for managing the service (Instantiating,executing,disposing).But DI decouples such tasks so the service consumer no need not worry about controlling the life cycle of the service. 2) He also asked is there any microsoft API follows DI ?.I answered (This was my guess) In WCF you can create a Proxy using ChannelFactory that controls the life time of your factory. for item (1) he said only 10% is correct for item(2) he said that is factory pattern not dependency injection. Actually what went wrong in my explanation (apart from my bad English) ? What is the real answers for those? I am waiting for your valuable suggestions.

  • MasterPage Page_Load hits before Grid_ItemCommand

    - by Raheel Khan
    I am using the session object to store success/error messages based on user actions. On each postback, the message is set on ItemCommend and retrieved on the Page_Load of the master page. Once retrieved, the message is deleted from the session. The problem is that the master page's Page_Load gets called before the ItemCommand gets called so the message does not show up until the next refresh or postback. How is this situation normally handled? Is there some other event we can code against?

  • A c# Generics question involving Controllers and Repositories

    - by UpTheCreek
    I have a base repository class which contains all the common repository methods (as generic): public abstract class BaseRepository<T, IdType> : IBaseRepository<T, IdType> My repositories from this base e.g.: public class UserRepository : BaseRepository<User, int>, IUserRepository I also have a base controller class containing common actions, and inherit from this in controllers. The repository is injected into this by DI. E.g. public class UserController : BaseController<User> { private readonly IUserRepository userRepository; public UserController (IUserRepository userRepository) { this.userRepository= userRepository; } My question is this: The base controller needs to be able to access the repository methods that are defined in the base repository. However I'm passing in via DI a different repository type for each controller (even though they all inherrit from the base repository). How can the base controller somehow access the repository that is passed in (regardless of what type it is), so that it can access the common base methods?

  • adding a token onto a webservice or wcf call

    - by duncanUK
    I have an httphandler which I am using to log the http soap request and response for each webservice that is called from my application as a comms log. i would like to inject a token ont he 1st call (possibly the 1st call to invoke the service that is being logged) and then be able to track all subsequent webservice calls run in the same context with this token so i can tie the subsequent calls back up to the original call. so for example. main webservice -> 2nd web service -> another web service [token] [token] [token] -> nth web service [token] I would like to inject the token on the first call to the main webservice (http handler checks if no token, add it), I would like to use the same http handler to intercept each call to the subsequent webservices and pass on the token if it exists already (the job of the httphandler is to log the in/out soap with the token to reference with. I have managed to inject the first token, but my problem is how do I add the token on the subsequent calls.. can I make it stick on the same context or session? My worry is that when we call a new webservice, we create a whole new proxy/http request which will not inhrit the token... or will it?! Ideally I would like it to persist on the http header as I am setting the token as a header at the moment? has anyone got any ideas or a better way of doing this? I would be most greatful for you comments!

  • Want to know about the best framework available for my app

    - by vamyip
    Hello, I am trying to design a new application which basically aims at providing biometric authentication services. What I want to do is that the app will present the user with an interface where the user can get his eye scanned for authentication. The most important feature I want to incorporate is that the user need not have a webcam, the app must be able to read the eye from the display device i.e. CRT or LCD screen itself. I want info about the best framework available for this. Once successfully tested, I am planning to provide it as a webservice. Any one who will help me will get a royalty from my income.

  • How can I access the value of a checkbox without a postback?

    - by Starwfanatic
    I have a radgrid controlling access to an application for users. There are two columns, a 'name' column and a checkbox 'access' column representing their current access permission. the checkboxes are populated from a database. I would like the to change the checkboxes to grant or deny access to the users I specify. Since there are alot of users I would like to make multiple changes and use a submit button to write the changes to the database. I do not want to postback with each checkbox change and wait for the page to "blink". My problem is that with the checkbox postback disabled, when I click submit, the value of the checkboxes are not registering the changes I make. I need a way to access the current client-side state of the checkbox or some workaround to accomplish this. Thanks in advance!

  • Using $.getJSON to perform cross domain request problem.

    - by Ahmed
    I'm using the following code to make cross domain request using $.getJSON, request completed but with errors, I cannot exactly detect what is the thrown error. Based on callback param of request value I route it to a certain method which retrieves required JSON data. $.getJSON("http://wthsrvr:45452/Handler.ashx/?Callback=DocumentReadStatus", { userID: vuserID, documentID: vdocumentID, format: "json" }, function(result) { if (result.readStatus == '1') { alert("ACCEPTED"); } else if (result.readStatus == '0') { alert("NOT ACCEPTED"); } else { alert(result.readStatus); } }); FYI: while development of this locally, everything worked fine, but after solution deployment to server and trying to do the same, I got that problem. Also, I tried the same functionality with web service, I got the same problem while calling web service from server. I'm using ajaxSetup to detect thrown errors. $.ajaxSetup({ "error": function(XMLHttpRequest, textStatus, errorThrown) { alert("textStatus: " + textStatus); alert("errorThrown: " + errorThrown); alert("responseText: " + XMLHttpRequest.responseText); } });

  • What is the best practice to segment c#.net projects based on a single base project

    - by Anthony
    Honestly, I can't word my question any better without describing it. I have a base project (with all its glory, dlls, resources etc) which is a CMS. I need to use this project as a base for othe custom bake projects. This base project is to be maintained and updated among all custom bake projects. I use subversion (Collabnet and Tortise SVN) I have two questions: 1 - Can I use subversion to share the base project among other projects What I mean here is can I "Checkout" the base project into another "Checked Out" project and have both update and commit seperatley. So, to paint a picture, let's say I am working on a custom project and I modify the core/base prject in some way (which I know will suit the others) can I then commit those changes and upon doing so when I update the base project in the other "Checked out" resources will it pull the changes? In short, I would like not to have to manually deploy updated core files whenever I make changes into each seperate project. 2 - If I create a custom file (let's say an webcontrol or aspx page etc) can I have it compile seperatley from the base project Another tricky one to explain. When I publish my web application it creates DLLs based on the namespaces of projects attached to it. So I may have a number of DLLs including the "Website's" namespace DLL, which could simply be website. I want to be able to make a seperate, custom, control which does not compile into those DLLs as the custom files should not rely on those DLLS to run. Is it as simple to set a seperate namespace for those files like CustomFiles.ProjectName for example? Think of the whole idea as adding modules to the .NET project, I don't want the module's code in any of the core DLLs but I do need for module to be able to access the core dlls. (There is no need for the core project to access the module code as it should be one way only in theory, though I reckon it woould not be possible anyway without using JSON/SOAP or something like that, maybe I am wrong.) I want to create a pluggable environment much like that of Joomla/Wordpress as since PHP generally doesn't have to be compiled first I see this is the reason why all this is possible/easy. The idea is to allow pluggable themes, modules etc etc. (I haven't tried simply adding .NET themes after compile/publish but I am assuming this is possible anyway? OR does the compiler need to reference items in the files?)

  • How to check which action method rendered the current view (from within the current view) ?

    - by Richard77
    Hello, I would like to know how to check which action displayed the current View (from the current view). For instance, to check if controller myController originated the rendering (I guess) I can write: <% if(ViewContext.Controller is myApplication.Controllers.myController)%> In fact, I want to use the same View model for 2 actions methods, like this: <% If( First Action rendered this view){%> // Display this <%} else {%> //Display that <%}%> Thanks for helping

  • Comparing Object properties using reflection

    - by Kumar
    I have two classes Address and Employee as follows: public class Address { public string AddressLine1 { get; set; } public string AddressLine2 { get; set; } public string City { get; set; } public string State { get; set; } public string Zip { get; set; } } public class Employee { public string FirstName { get; set; } public string MiddleName { get; set; } public string LastName { get; set; } public Address EmployeeAddress { get; set; } } I have two employee instances as follows: var emp1Address = new Address(); emp1Address.AddressLine1 = "Microsoft Corporation"; emp1Address.AddressLine2 = "One Microsoft Way"; emp1Address.City = "Redmond"; emp1Address.State = "WA"; emp1Address.Zip = "98052-6399"; var emp1 = new Employee(); emp1.FirstName = "Bill"; emp1.LastName = "Gates"; emp1.EmployeeAddress = emp1Address; var emp2Address = new Address(); emp2Address.AddressLine1 = "Gates Foundation"; emp2Address.AddressLine2 = "One Microsoft Way"; emp2Address.City = "Redmond"; emp2Address.State = "WA"; emp2Address.Zip = "98052-6399"; var emp2 = new Employee(); emp2.FirstName = "Melinda"; emp2.LastName = "Gates"; emp2.EmployeeAddress = emp2Address; Now how can I write a method which compares these two employees and returns the list of properties which have different values. So in this example I would like the result to be FirstName and Address.AddressLine1 .

  • Why wouldn't I be able to establish a trust relationship for a SSL/TLS channel?

    - by Abe Miessler
    I have a piece of .NET code that is erroring out when it makes a call to HTTPWebRequest.GetRequestStream. Here is the error message: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. I've read a few things that suggest that I might need a certificate on the machine running the code, but i'm not sure if that's true or how to do it. If I need to get a certificate, how do I do it? Code: var request = (HttpWebRequest)HttpWebRequest.Create(requestUrl); //my url request.Method = StringUtilities.ConvertToString(httpMethod); // Set the http method GET, POST, etc. if (postData != null) { request.ContentLength = postData.Length; request.ContentType = contentType; using (var dataStream = request.GetRequestStream()) { dataStream.Write(postData, 0, postData.Length); } }

  • How do I implement a Google Latitude check-in feature on Windows Mobile?

    - by Carnotaurus
    I hope this is the correct forum. I wish to write a mobile application (MVC 4 mobile app) that extends Google Latitude for Windows Mobile 7 (or version 8 when launched in November). However, according to Google's own website (see http://www.google.com/mobile/latitude/), the check-in feature is not supported on Windows Mobile. So, how would I implement such a feature (not so interested in the UI here) using the technologies that I have mentioned? EDIT The implementation needs to store check-in data against a Google Latitude account.

    I want to be able to add a parent column header to each pair of columns shown below. So I want it to look like this: Grand Total OnHand Available Anyone know a way to do this? I know you can group columns together but I'm wondering how I can apply a label to those groups. Alternatively, if theres no way to do that, I could just override the "Grand Total" display text. The only problem is I can't get it aligned above its correct columns.
