View 10 RepliesI am starting an MVC application and designing the class libraries structure at the moment. I started off with the following class library structure as below.
[code]....
As there will be about 3-4 developers working on the project I thought it might be useful to split out each section of the application into their own class libraries so each developer can work on a different section without interferring with each other.
In our application we have 5 tabs e.g. Dashboard, Admin, Reports, Editor, Subscribers. Would it be wise to put each tab into its own class library like below.

i am new to WebServices, i have a ClassDataLibrary.dll which include classes like Users,Products,Articles...
i want to create a structure like this in my webService. as i saw the examples of creating web services the web methods written on the same page. but i got over 50 methods in dll and i want to share these methods with flash so flash user get data using my webService but it will be difficult to find the method he wants so i want to give my webService in a structure like:
Service1.Users // he will finds the methods about users
Service1.Products // he will finds the product methods
how could i do it ? is there any example or something to share with me?
I'm building an application where custom modules may be developed and "dropped in" to the system, where they can be picked up and utilized.
I'm building a forum module and have a user control to create a login/registration region. I plan on using a struct to store the user session data. However, i need this class structure to be shared between the forum module and the login/registration control.
Because the functionality is to be contained in the module's folder, i cant add any assemblies to the app_code folder.
How can i share a class or struct among two user controls?
I 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).
What is the difference between HttpApplication class and IHttpModule? Are they both same or different?
I see articles that mention the same events in both the classes.

View 1 RepliesWe are currently building a site in ASP.net MVC 2 and we have discovered that the URL's we have specified are not supported by MVC. This is what our developers are telling us anyway. I'd like to get feedback form this forum. My asp.net MVC knowledge is limited (I am an old school ASP 3 guy who hasn't programmed for years) but am trying to learn as much as I can so I can understand the limitations. say for example the app is a jobsearch site in the healthcare sector e.g. we would like the urls to be the following:
1. (non advanced searech) [URL]
2. (advanced search) [URL]
they are telling us that they need to send all parameters in the url even if they are blank so our example 1 here would not be possible. It would need to contain all of the possible advanced parameters in the search like this: [URL] most seaerches are basic i.e. looking for job in a location. but users have the optyion to do an advanced search also. The dev is telling us that we must send all params empty in the URL even in a basic search. Has anyone come across this limitation beforee and if so how did you combat it?

i have to build a ASPNET website on which some functionalities will be available to logged in users.I'm trying to understand the right thing to to in building my pages.
I've found the following code in Page_PreInit:
protected void Page_PreInit(object sender, EventArgs e)
{
if (Membership.GetUser() == null) //check the user.. Weather user is logged in or not
{
this.Page.MasterPageFile = "~/General.master";
}
if (Membership.GetUser() == "ADMIN") //check the ADMIN.. Weather ADMIN is logged in or not
{
this.Page.MasterPageFile = "~/ADMIN.master";
}
else
{
this.Page.MasterPageFile = "~/Member.master";
}
}
..but i don't' know if this is the right approach in designing an app.Is it right to switch at runtime Master page according to username/role?

I have inherited a piece of code that is a bit of a pig. It uses a cursor to loop through a list of stores and count customers.

Loops through the stores Insert a new record into the Destination Table Count up the new customers for this store Count up the returning customers to the store Update the new record with the totalsLoopThe code:

I have a large directory structure with JavaScript, images, etc. that depend on each other. I would like to encapsulate it all into a DLL so I only have to reference one thing and not have multiple copies of all these files across projects.
Because the files depend on each other, I'm thinking I can create an IHttpModule that registers a route to accept URLs such as /MyEmbeddedDir/subdir/file.js. Anything in MyEmbeddedDir would then be handled by a custom IHttpHandler that does the correct mapping. Each web application would then need to reference the DLL and add the module and handler to web.config. Does this seem reasonable?Also, is there an easier way to embed/reference the files than to set the build action to embedded resource and add [assembly: WebResource(...)] to each file (there are dozens!)?Edit: If I'm not using WebResource.axd then I shouldn't need to add [assembly: WebResource(...)]
I have a datatable which i get from the databasemanager class, and i would need to transform that data into a hierarchical structure
either binding it directly to a .net treeview control or in memory first .
i have an ID column, and a ParentID column.what i do not know necessarily is the parent ID to start with. so first thing to do would be to find out which node is the parent ID.
what would be best practice to loop over this table and make it hierarchical
BranchId ParentId ProductCount HasBranchChildren Name
0 NULL 48 1 Categories
1 0 20 1 CategoryA
2 1 10 1 CategoryA1
3 1 8 0 CategoryA2
4 1 2 0 CategoryA3
5 2 4 0 CategoryA1.1
6 2 6 0 CategoryA1.2
7 0 28 1 CategoryB
8 7 20 0 CategoryB1
9 7 8 0 CategoryB2
this would be an example datatable of course it will have hundreds of items, and it does not always start at the root node, its possible that with a request a certain subset of categories is requested, however i've talked with the database team and they will give me NULL on root nodes in the above example that would be element 0 in the table ....
Typically I would have ran with the traditional 3-Tier approach but after spending some time looking around at various options I've got an inkling that some kind of ORM might be a better fit and I'm considering nHibernate.However,I'm looking for some guidance on implementing nHibernate and more specifically how I would structure my BL and DAL in conjunction with nHibernate.With nHibernate I would create my Objects (or DTOs?) and use nHibernate methods for my CRUD interactions all in my DAL.But what I can't get my head around is the Objects defined in the DAL would be probably be better situated within the BL, i.e. where validation and other stuff can be performed easily, and I just use the DAL from the various ObjectFactory's / ObjectRepositories. Unfortunately it seems through the many articles I've read this isn't mentioned or skirted over and I'm a tad confused.What is the more accepted or easier method of implementation when using nHibernate in a 3 Tier system?Alternatively, what is the conventional method of exposing objects through the business layer from the data layer to the presentation?
View 5 RepliesI am trying to learn LINQ to entities, and am working out how to best structure my BLL layer. I have generated the entity model and have created a generic repository in my DAL that returns results as IList<T>. I initially created the BLL to also return
results as IList<T>:
public IList<DAL.Customer> SelectAll()
{ [code]...
Now I am working on the aspx page, and I can create an ObjectDataSource and configure it to use my BLL, but since I am returning IList, I can't sort since I am not using a DataView. I have seen some articles on the web for converting IList to DataView, but that seems like a lot of overhead for every query.My goal is to keep a clean separation between layers without making things overly complicated. I would like to know how others have done this, or maybe a link to a good tutorial that shows how to structure all three layers.

ASP.NET, web form model.Is there any sample code/site that demonstrate a couple samples for regular website patterns/ templates? Like if I want to use tab to switch between different pages, should I put the code in a single page or in different page, and treat each tab as a page.Or if in a search page (just a single search bar and button), should I display my result panel in same page using dynamically enable the result panel, or just to another page? I want to find a general design pattern/ template.
View 2 RepliesWhats the best way to return a tabular structure from an ASP.NET (2.0) web service?
It should be inter-operable with Java, Iphone App or any other platform.
EDIT: By inter-operable I mean the other technology/client should be able to consume it or deserialize it to their native types, instead of parsing response XML.
I want to structure my ASP.NET MVC 2 web application sensibly using Areas. The application consists of the two main parts Website which is the default part and Dashboard which administrates the site using a CMS. (Probably, more Areas will follow later on.)
How do I structure my project best? Should I ...
create the Area Dashboard and put the stuff belonging to the Website part into the main application folder or should I create both Areas Website and Dashboard?
Additionally, where should I place my Entity Data Model and the corresponding Repository classes that have to be accessed by both Areas?
I am using asp.net 3.5 and I am trying to create a project structure (asp.net web solution with UI/Business/Data access) which would be like a base and ready for any new projects in my team and all could use this standard structure only as a base(outer boundary) and they can expand the structure. Also adding on to it I wanted to include certain features like adding libraries of reusable code/functions, so that every team member could use functions from my library within this base structure. To summarize the above, I need to create standard .net project structure/framework/architecture with resusable code library included in it. How can I do this..
View 4 RepliesI'm building a site that can possibly have millions of users (yes ambitious!). Each user can upload an image or two for his/her profile. How would you architect the directories to support this type of thing? I was thinking of having a users subfolder off the root dir where each user will have their own sub-dir that corresponds to their userId created at registration time. I could then upload their profile pics to their corresponding sub-directory under the users dir. Seems straightforward but am I missing anything? Can I have a million sub-dirs under the user dir? NTFS supports it so my guess is YES.
