Is there any way to generate all classes and interfaces as we create manually for 3-tier architecture...
Or do i need to generate manually...

Forms Data Controls :: GridView Bug With Interfaces?
Dec 6, 2010If you try to use a property as a column for a gridview where the value is coming from an implicitly implemented interface, the value will not be found and throw an error. Even if you pass in a List of the interface.DataBinding: 'Class' does not contain a property with the name 'Field'.
View 4 RepliesC# - EF4: Compex Inheritance With Interfaces?
Mar 17, 2011I'm using EF4 to generate a model. My architecture looks like this:
IMyEntity (custom interface)
-> MyEntity - EF generated class
IMyOtherEntity (custom interface)
-> MyExtendedEntity (Customn Partial class) : MyOtherEntity (EF Generated)
The first entity has a list of MyExtendedEntity. Is there any way I can bind this with the entity framework. I'm targetting ASP.NET and WPF. The main probnlem I have is that I need an ObservableCollection in WPF, while the EF generated class only has an EntityCollection which doesn't even seem to derive from ObservableCollection.

View 2 RepliesRecommendations For Abstract Class Vs Interfaces?
Dec 21, 2010From the following URL i got some doubts about the Recommendations for using Abstract class vs interfaces
[URL]
1. If you anticipate creating multiple versions of your component, create an abstract class. Abstract classes provide a simple and easy way to version your components. By updating the base class, all inheriting classes are automatically updated with the change. Interfaces, on the other hand, cannot be changed once created. If a new version of an interface is required, you must create a whole new interface. { Is there any example for this t ounderstand throughly ?} If you are designing small, concise bits of functionality, use interfaces. If you are designing large functional units, use an abstract class. If you want to provide common, implemented functionality among all implementations of your component, use an abstract class. Abstract classes allow you to partially implement your class, whereas interfaces contain no implementation for any members. { Is there any example for this t ounderstand throughly?
WCF / ASMX :: SSO Authentication Token And POX Interfaces
Jul 28, 2010We have a SSO authentication service that other externally facing web pages and services use to authenticate users. A user tries to reach a service, if no cookie is found containing an authentication token, they are redirected (HTTP 302) to the SingleSignOn authentication service. The auth service does it's work, and redirects the user (HTTP 302) to the original URL with their encrypted authentication token in the URL. Great. How can I invoke this from a WCF POX service? No SOAP here, just HTTP GET/POST with XML responses.
What I'm currently doing is, in each service method implementation method, checking the headers for the cookie. If the cookie exists, verify the auth token and process the request. If the cookie doesn't exist or the auth token has expired, then respond with:
[Code]....
That works, but isn't integrated with any of the WCF features, and requires me to manually code for a whole bunch of scenarios. Is there a way I could implement this using these classes:
[Code]....
or use some other means that checks each request to the service? I've been reading pages like: How to: Create a Custom Token, but I don't see how it applies to my needs. I'm looking into this because I have some time before my project kicks off, and I'd like to implement this project correctly and learn about WCF as much as I can.

WCF / ASMX :: Standardizing Interfaces To External Clients To Consume Wcf Services
Jul 9, 2010I have a build a new 3 tier application (Web,Application,Data tier). The application tier (middle tier) will host wcf web services. I build my service classes, define bindings , contracts etc which does the core business logic, data access and updates.
Now I have around 50 external clients who would want services from my application tier. But my problem is client A might send a flat file request, client B might sends a comma separated file request, client C might be a soap request. The requests further may be either real time or batch. My services may have to send data back to the caller either in a flat file.., xml or a soap response or other formats. The response might also be either batch or real time.
1)Is there a way to standardize the interface for all these 50 clients accessing my WCF services ?
2) If an external client sends a flat file via FTP (intended to serve as input to my service), how do I get this flat file data to hit my service. (Assuming that the legacy system is not service based and hence the external client just sends a file and is not aware of any services of the new system)
SQL Reporting :: Microsoft.ReportingServices.Interfaces.dll Missing For SSRS 2005?
Mar 11, 2010I am missing this DLL reference in c:program filesSQL Server90ToolsBinn. I'm assuming that this is because I didn't install the 2005 client. I installed all of the services for 2005, the database instance, reporting services instance, SSAS and SSIS. I installed the 2008 client though, not the 2005 client, and 2008 database instance.So I assume it's because I didn't install the client, but does something else give me this DLL? Another install or a SDK or something?

View 7 RepliesMVC - Factor Repository Interfaces Based On Multi - Level Object Model?
Feb 15, 2011I've got a multi level dependency chain in my object model: An organization has the following children relationships:
Organization
.CompetitionGroups
.CompetitionGroups.Venues
.CompetitionGroups.Competitions
.Divisions.Games
.Divisions.Games.Participants
.Divisions.Games.Participants.GameSegments
.Divisions.SubDivisions...
.Divisions
.Teams
.Teams.Players
.Teams.Participants
.Teams.Participants.GameSegments
.VenueDates
This is just a glimpse at the object model, but it's focused on the complexity of the relationships and lists. What I can't really get is what's the best way to factor my repository interfaces, given the requirements to do a unit of work. For example, to create a game, you'll need a venuedate and two participants. Does that mean the GamesController should require an IGameRepository, an IVenueDateRepository, and an IParticipant repository? Should they be rolled into one repository?
Also, what about in the consumption cases? For example, to display a signle team's schedule, you'll need all of the Participants for that Team, all of the Games for that participant, and all of the GameSegments for the participant. If those are factored into individual repositories I can't see how you can do efficient queries. Does that mean you have Repositories specifically focused on different cases? for example:
public interface IScheduleRepository {
public ICollection<Game> GetScheduleForTeam(Team team);
// More consumption methods
}
public class ScheduleRepositry : IScheduleRepository {
public ScheduleRepository (ModelContext context) {
// Do stuff with context
}
public ICollection<Game> GetScheduleForTeam(Team team) {
return (
from p in context.Participants
where ((p.Game.VenueDate != null) &&
(p.TeamId == team.Id))
orderby p.Game.VenueDate.StartTime
select p.Game).ToList();
}
// more consumption methods
}
public interface IGameRepository {
public void AddGame(Game game);
// More crud methods
}
// Not showing games repository
public class GamesController : Controller {
public GamesController (IGameRepository gamesRepo,
IVenueDateRepository venueDateRepo,
IParticipantRepository participantRepo) {
// do stuff with repos here
}
[HttpPost]
public ActionResult AddGame(Game game) {
// Skipping validation logic
// this?
VenueDate = venueDateRepo.Add(game.VenueDate);
foreach (Participant p in Game.Participants)
{
participantRepo.Add(p);
}
Game = gamesRepo.AddGame(game);
// or this?
// how would the game repo know to persist
// the children elements? is that tight coupling?
Game = gamesRepo.AddGame(game);
}
// more consumption methods
}
My question is I don't yet understand to what degree factoring your repositories make sense based on a connected object model. I'd love to get some advice here.

Web Forms :: Get A List Of All Classes That Inherit From BasePage In The Web Application?
May 13, 2010I need to get a list of all of these webforms.
As the subject reads, how can i accomplish this ? All my webforms inherits from a class called "BasePage". It can also suffice with only getting a list of all the webforms in the application, regardless of base class since i can check inheritance later in code.
Reason i'm asking is because i'm building my menu and i'm implementing security enforced user visibility based on what pages there are in the webbapplication, and what roles each page demands, and display these to the user in the menu.
Using sitemaps are insufficient, i need to provide much more info for all the pages i have on my system.
Using this technique i can query my "PageProvider" for like:
GetAllPagesVisibibleToUser(MembershipUser user)
DoesUserHaveAccessToPage(MembershipUser user, BasePage forPage)
I'm also planning on implementing this technique on WebUserControls.
MVC :: How To Inherit Two Classes Using Page Directive
Aug 10, 2010I have been trying to find a way to declare two classes using page directive, but it seems like mvc framework doesnt support it.
I have got :
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<IEnumerable<ContactManager.Models.contact>>" %>
which shows the list of the contacts including edit delete and create option.
What I need to declare another model class which is FileRepository.cs for uploading files on the same page. In this case the page directive should be like:
2. <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<IEnumerable<ContactManager.Models.FileDescription>>" %>
Is there any way I can incorporate both into one as the first is coming from the database.

C# - Class Structure With LINQ, Partial Classes, And Abstract Classes
May 17, 2010I am following the Nerd Dinner tutorial as I'm learning ASP.NET MVC, and I am currently on Step 3: Building the Model. One part of this section discusses how to integrate validation and business rule logic with the model classes. All this makes perfect sense. However, in the case of this source code, the author only validates one class: Dinner.
What I am wondering is, say I have multiple classes that need validation (Dinner, Guest, etc). It doesn't seem smart to me to repeatedly write these two methods in the partial class:
[code]....
This doesn't "feel" right, but I wanted to check with SO to get opinions of individuals smarter than me on this. I also tested it out, and it seems that the partial keyword on the OnValidate method is causing problems (understandably so). This doesn't seem possible to fix (but I could very well be wrong).
C# - Can Base Classes See The Protected Fields Of Derived Classes

Map Model Classes To ViewModel Classes Or Aggregate Model Classes In ViewModel Classes
Dec 15, 2010I'm curious as to what people consider better practice, between duplicating model structure in the view model and using a mapping tool to move data between the two, or aggregate the model inside the view model, i.e. have a property on the view model class that is a reference to the actual model. Which is considered a better approach in general?
