Polymorphism question

edhc44 — Mon, 23 Nov 2009 20:22:25 GMT

Hello all. I'm developing a system where I'm gonna use inherited classes and polymorphism to control its state, however, I ran into a setback. In my model, all possible states are gonna be derived from a base abstract State class, since I want its behavior to change dynamically depending on which state it is (therefore, I won't need a ton of switches and if/elses; polymorphism works great in my case). The base class has a virtual method to access the database which is overriden by all derived classes, since diferent fields on the DB will be updated depending on which state the system is in.

But it's not all about system state. The system has an "Edit mode" and I want the system to have a different behavior regardless of the state it is when calling the method to update the database - this behavior is different from all states but it is the same no matter what state the system is. To make it clear, depending on what state the system is, a different set of fields will be updated in the database when submiting data, but in edit mode, I want ALL fields to be updated. Before calling the update method, I tried to check if the system is in this state and if it is, I tried to cast the object calling the updateData method to the base class and call its implementation, but it doesn't work and I read somewhere else that it's not the way to do it (unfortunatelly, they didn't say what IS the way). I wrote a very primitive system that mimicks the actual system workings to further clarify the problem:

File State.cs

    public enum SystemStatus
    {
        INITIAL, FINAL
    }

    public abstract class State
    {
        protected SystemStatus systemStatus;

        public virtual string UpdateData()
        {
            return "Update all fields.";
        }
    }

File StartingState.cs

    public class StartingState : State
    {
        public StartingState()
        {
            systemStatus = SystemStatus.INITIAL;
        }

        public override string UpdateData()
        {
            return "Update fields regarding the initial state";
        }
    }

File FinalState.cs

    public class FinalState : State
    {
        public FinalState()
        {
            systemStatus = SystemStatus.FINAL;
        }

        public override string UpdateData()
        {
            return "Update fields regarding the Final State.";
        }
    }

File Program.cs

    class Program
    {
        static void Main(string[] args)
        {
            StartingState startingState = new StartingState();
            FinalState finalState = new FinalState();
            State currentState = startingState;
            bool editMode = false;

            Console.Write(@"Currently the system is in its Initial State.
Press 'f' to go to the Final State or 'e' to go to Edit Mode.
Press return to call the Inicial State method
");
            switch (Console.ReadLine())
            {
                case "f": currentState = finalState; break;
                case "e": editMode = true; break;
                default: break;
            }

            if (editMode)
                //In Edit Mode, I want the system to update all data (use the base class method implementation)
                Console.WriteLine(((State)currentState).UpdateData());
            else
                //Else, I want it to use the implementation regarding the current system state (initial or final)
                Console.WriteLine(currentState.UpdateData());

            Console.ReadLine();

        }
    }

I don't thing using statements or namespaces are necessary to paste here and I added the enum attribute just so people don't think the only thing the derived classes in the actual system do is calling the updateData method.
Anyway, I thought of two possible solutions to this problem.
1) Instead of trying to cast the currentState object to the base class, create an instance of the base class and call the method directly. That doesn't work because the State class is not an actual State hence it would be stupid to instantiate it (I even made the class abstract);
2) Create a non-virtual method in the base class, an "UpdateAll" of sorts and leave the UpdateData to be implemented only by the derived classes. Then, upon checking if the system is in Edit Mode or not, I'd call the currentState.UpdateAll () and that would be it. I don't really have a problem in doing so but... Is it the right way to do it? If not, what's the best way to solve this issue?

Does web.config files in subfolders not support ?

Cybrosys — Mon, 23 Nov 2009 13:45:08 GMT

Here's a dilemma:

I am developing for a CMS (Content Management System) and the "modules/apps/widgets/..." can reference and add any dlls to their "module". The problem is that all the "modules" has to place their assemblies in the CMS' /bin folder of course, otherwise the IIS won't find them. So how can i avoid conflicting .dll names and third party control versioning hell (one modules uses v3 of a control while another uses v4 and depending on which module was installed last, that module's version of the .dll will overwrite the other one).

So i found out about:

    <runtime>
        <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
            <probing privatePath="" />
        </assemblyBinding>
    </runtime>

However, the modules can't modify the CMS' web.config file, all they can do is have their own web.config files with the above information that is placed in the module's subfolder, for example: /Custom/Modules/Blog/web.config

Here's the part that's upsetting, the above xml does not work unless it's in the CMS' web.config file, which renders it moot since the module's can't modify the CMS' web.config file...

The dream scenario would be that the /bin folder is always searched recursively when a .dll needs to be loaded, thus every module can create their own subfolder in the CMS' /bin folder.

Data Access Layer help

JBeckton — Sat, 21 Nov 2009 04:30:52 GMT

Trying to learn ASP.Net but becoming increasingly confused about data access.

Looking at building a web app with ASP.Net I could not imagine not using some sort of separation of my database code from my UI code at the least, I also prefer using a service or business layer. So I am really trying to focus on implementing these layers properly. I am just learning .Net so I am not interested in anything too difficult like an ORM and such.

The problem I am having is I read in many places that using datasets can lead to performance hits and the datareader is the most efficient way. But all the books, online tutorials as well as videos I have purchased all demonstrate using datasets and very little if any on just plain datareader implementations. I also just read an article that mentioned passing a datareader up through the layers of your app is not possible so one would have to serialize the reader results or use collections etc.. but data bound controls require either a dataset or a datareader object.

So if I am using a DAL and BLL can I use datareader? Unfortunately all the books and videos I have fail to explain in depth how to implement n-tiers and how they all communicate with each other.

As for the methods in my DAL; getProducts(), getCategories() etc... what datatype should they return? a dataset or a datareader? if I need a dataset can't i just create it in my BLL from the datareader that is passed up from the DAL?

If I use objectDataSource shouldn't that call methods in my BLL which in turn get the data from the DAL? if so what should my DAL return, a dataset or datareader?

and lastly, datasets seem alot easier to use and have more features that the datareader; are they really all that bad on performance?

A question of threading in my application

dogcow813 — Sat, 23 May 2009 22:12:55 GMT

First let me preface by saying I am a LAMP developer for 12yrs. I am new to .NET, I work in a LAMP shop but we need to use .NET to get this project working. Heres the situation, we have a windows program that can take a street address and return long/lat coordinates from it (geocode). It has an API in C. We wanted to take these methods and expose them as a webservice so our LAMP based applications can access them and we can access them in javascript. I've managed to import the unmanaged C functions into C# already and have a basic running ver of it. The problem is this.. the software limits you to only 8 concurrent API instances at one time. However, each API instance allows you to perform 32 concurrent geocode within that instance at once. So right now, I have it set up so each instance of the web service controls an API instance. It uses the threading.semaphore class so that if you call more than 8 instances at once, they have to wait until others finish ( or return a too busy error if timeout). My question is there a way to set it up so that we can use the full power of 256 concurrent searches (8 instance * 32 search threads) ? In case you are wondering, the software we're talking to through the API is designed for batch querying , we want to use it to just do 1 address at a time. Any help would be GREATLY appreciated.

VB.NET Class structure issue

nileshbs — Mon, 23 Nov 2009 08:03:58 GMT

Hello friends,

I have little doubt in class structure.

I have following tables

ChannelMaster (Id, Name, Status)

SubChannelMaster (Id, Name, Status, ChannelId)

Entity (Id, Name, Status, ChannelId)

SubChannel_Entitty (SubChannelId, EntityId)

What will be the Class structure for this? should I create classes for each table and add objects of reference classes (tables) or is there any another way?

thanks,

nilesh.

Generating and compiling C# code from within an ASP.NET application

davepl_ms — Fri, 20 Nov 2009 20:38:19 GMT

I have an ASP.NET 3.5 web application that generates, compiles, and invokes a method to evaluate some complex math equations. Works great on my dev environment, but on the deployment machine I am running into permission problems.

The first was the location of the compiler temp files, which I moved to the current folder and that fixed that. But now I am faced with w3wp.exe generating access exceptions when it tries to do the compile.

Short of locating everything on the machine that the compiler needs and granting the ASPNET account access to it, what's the best solution here? And if there is no better solution, how do I determine the canonical set of things that ASPNET needs access to? Obviously, I'm not thrilled with the prospect of cascading access too widely.

Thanks!
Dave

Swapping out a Data Access Layer

Freakish_05 — Sun, 22 Nov 2009 20:33:38 GMT

Hi Everyone,

A general achitecture query query really...

I'm creating a component that may have to use different types of datasource (i.e. SQL, XML) depending on the deployment sinario.

I've already written all the code for a SQL deployment and I've used the repository pattern in much the same way that Rob Conery did with his MVC Storefront tutorials.

Can someone please tell me how best to achieve this? I've tried refactoring the data access classes (mainly the repository stuff) into a separate assembly but because both assemblies (business logic and data access) need to know about the interface, I'm getting a lot of circular dependency errors in Visual Studio.

My thanks in advance for any contributions to this thread.

Recommendation System

valerio006 — Sun, 22 Nov 2009 17:49:59 GMT

I am creating a web system which recommends submitted articles that are on the database to the current logged in user...are there any sort of publications that you know of that can push me in the right direction when it comes to actually implementing this sort of thing? Right now the system just displays all articles from the database onto the front page, regardless of who you are logged in as. I have seen numerous algorithms and system archtictures, but when it comes to actually PROGRAMMING a recommendation system, I'm still rather clueless...any ideas?

Business logic layer

Mitja Bonca — Sun, 22 Nov 2009 13:03:55 GMT

I am learing programming for a bit more then 6 months, and recently someone told me my concept is not the best one, he proposed me that I rather split my code into business logic layer and data access layer.

And now I would like to ask someone if he can help me out on a simple example of how to do business logic for this example (it`s about library):

Database tables(Parameters):

1. Author (IDAuthor, Name, SureName)
2. Book (IDBook, IDAuthorFK, Title)

I would like to have methods:
1.1. Get author name and surename
1.2. Add new author (insert)
1.3. Update author
1.4. Delete author

2.1 Get books (returns all books)
2.2. Get book by author`s ID (returns a value by author`s ID)
2.3. Add new book
2.4. Update book
2.5. Delete book

How to create Business Entities in .Net.

NagarajuK — Thu, 19 Nov 2009 11:13:45 GMT

Hi,

I got a chance to design an architecture for a .net web application using .net 3.5. I started creating the architecture by defining the following three layers.

1. Presentation Layer.

2. Business Layer.

3. Data Access Layer.

Now, I need to create a common layer called "Business Objects"(Entities) where I need to create entities using classes.

Can you please clarify the following queries?

1. Should I create a seperate entity(class with fields and properties) for each database table(more than 100 tables are there)?

2. If I create entity for each database table, how can I get different columns from different tables using sp/select query?

Thanks in advance.

ASP.NET Shopping Cart Design - SQL Table or Session Variables?

BKirk — Mon, 16 Nov 2009 05:29:53 GMT

To date i have been using ASP Classic, SQL Server Standard 2005 and Dreamweaver as my web development tool of choice.

Now i'm moving into ASP.NET with VWD, SQL Server 2005 and want to replicate my shopping cart system as best i can.

I have been using the WebAssist eCart product for all my ASP Classic shopping cart needs which is incredibly powerful and flexible. Only problem is they don't have a .NET version so i've decided to build my own from scratch.

I was wondering the best approach for ASP.NET shopping cart design. I figure there are probably only 2 ways i'd like to go but not sure of the PROs vs. CONs?

1) SQL Table design for storing all current cart sessions (public or logged in); OR

2) Session State using Variables in current browser - This is how Webassist eCart was built which worked pretty good.

Is there are special way i can contruct a secure, highly functional and customisable shopping cart in ASP.NET using classes, sql tables? Or sessions?

High Volume Websites Strategies...

Mark DotNet Evans — Wed, 18 Nov 2009 10:02:00 GMT

Hi Folks, does anyone have any advice for designing high volume websites? All the sites I have done in the past have been relatively low demand sites so are there any techniques or considerations that I should be aware of when tackling this new website?

All my sites employ N-Tier OOP architecture and I try to minimise the work the asp engine has to do on a per hit basis (be that using ajax or just through data organisation) so I'm wondering what other things I need to consider?

Cheers

Hierarchical Roles

nick7272 — Fri, 19 May 2006 23:18:23 GMT

I'm having trouble coming up with a good way of handling roles in my application. I would like roles to have a hierarchy, such that if a user is in the role "Sargeant" he can do all the things a "Foot Soldier" can do.

For the purposes of my example, assume my role hierarchy is:

General
-> Lieutenant
    -> Sargeant
       -> Foot Soldier

Problems:

1. The .NET security framework doesn't support a hierarchy when it comes to controlling access to views. In order to give access to a view to all of my roles, in a web.config file I would have to list all of them. I would prefer to simply say "Foot Soldier" can access the view and assume that that implies that "Sargeant", "Lieutenant", and "General" can all access the view.

When dealing with this at the level of the domain it's not an issue. I can rewrite the IPrincipals IsInRole method to check whether a particular role is a child of another role. I'll be doing this at the service/business facade layer.

2. Where to store the hierarchy? I assume XML is the best for this purpose since once can easily define a hierarchy and XPath queries can easily tell me if a more specific is a child of a more general role. This is especially true if I have many branches to my role trunk. E.g.

    Role 1
       Role 2
          Role 3
       Role 4
          Role 5
             Role 6

I would want to say that Role 4 can do whatever Role 6 can do but not what Role 3 can do.

3. Relating users and roles. Roles must be represented as strings for the .NET security framework, but are classes in my application. Therefore, I've given each Role class a Name property. When I create my IPrincipal, I iterate through the User's roles and add each Role.Name to the IPrincipals private role collection. I'm not particularly happy that I have to represent roles in two different ways but I can't think of any alternatives.

Anyway, these are some of the problems I'm dealing with. Does anyone have any thoughts?

Creating methods on runtime with database-values

johannes.hiemer — Mon, 16 Nov 2009 22:07:15 GMT

Hi,

I got a question regarding dynamic method creation on runtime. My case looks like that: I have a database that stores different plattforms, each with different commands for doing the same thing in their enviroment. As an example for visualisation we take the method CreateUser().

Plattform 1: CreateUser(string username, string password, string birthday, string email)...

Plattform 2: CreateUser(string username, string password, string email, string birthday)..

Depending on the type of runtime I want to call one of those methods getting the method-heads from the database. The example above is quite simplified. There much more complex cases. The methods are webservices.

Is there any chance to that?

Thanks a lot for all ideas and help.

Access to page properties with bridge pattern

eniac0 — Thu, 12 Nov 2009 20:18:23 GMT

Hi, ok so title is cryptic, and yet i couldn't think of a better wording, allow me to explain.

I'm working on class that needs to provide the same functionality to two types of pages. To be specific, I have two sections in my application that are significantly different from each other but very close for a small part.

So, i created a base class and thought I'd just write a specific class for each that inherits. Both that doesn't do because we're in vb.net and the specific classes already inherits from a base class that THEY NEED to inherit from, a base class providing ground work for the specifics of the section.

So instead, I created an interface that matches the base call to be inherited from and made a bridge in the specific classes. following me ?

Now, i thought this was a done deal, everything compiles, i feel its actually beautiful as far as code can pretty. but it doesn't work. I'm not sure why but i believe i know why (but not sure what to do)

The error that i get is that the Session object does not exist when the base class tries to get the enumerator of the keys collection. I think its because the base class is not in the context of the page (since i simply do a _base = new BaseClass)

and, if I'm correct, what's the proper way to do this ?

Thank you so much.

Here's some code to help you understand, I've tried to reduce it only to what matters.

(its a bit lenghty but i try to give you bits of all the involved section)

Referencing a project from diffrent solution

Zcumbag — Mon, 16 Nov 2009 08:20:20 GMT

Hi,

I have a solution wich includes a SilverLight-project of mine. I want to somehow add a reference to this project (ie it's xap-file) from some of my asp.net projects that exist in other solutions. How would I do this? Can I register my SL-project as an assembly in my asp.net-project?

PS. I could ofcourse simply refernece its virtual path on my localhost, but that does not sound like a good solution, perticularly not when I want to deploy my asp.net solution.

Need Some Info from Ajax Programmers

geminizebra — Sun, 15 Nov 2009 22:03:40 GMT

Hi, everyone!

I’m working on an entrepreneurship project and my group needs your help in figuring out some of the details.

To give you the basic rundown of our project, our idea is to develop a new experience when shopping online. Instead of using the traditional, linear online storefront, customers will use a very user-friendly online web application (programmed with Ajax) to shop. We want to simulate the experience of physically shopping by having a layout of the virtual store in front of them. The most important thing is that the application needs to sync up to retail databases to show inventory availability.

Since many of you are programmers, I need information regarding the set-up and operations of this project. Even your best rough estimate would be incredibly helpful. If you could answer just one of my questions, I would be extremely grateful.

It’ll take quite a bit of server space to store the information within the application, but how much server space, bandwidth, etc. will be necessary to maintain this kind of application?
How would graphics, usability features, customization, and anything that makes the application more complex affect customer’s ability to access the application, affect the cost to maintain, etc.?
How long would it take to program and set up this kind of application?
How much would it cost to set this up?
How much would it cost to maintain this?Ajax looks like the best programming option, but is there another you think would work better?
How much would it cost to set up the actual website that would be hosting the application?
I know Google Maps uses something similar to this – would having the store in 3D be too much for it to handle?
If you have any extra information on cost, time, set-up, operations, etc., please let me know!

Thank you so much for your help! If you’re willing to talk to me a little more, explain how programming this would work or if you know anyone who I could contact to get more info, I would love the extra resource. Please just send me a PM and I’ll give you my contact info.

Thanks,

Hi there,

Cheers, WT.
