I'm planning to build "job search" website using (asp.net3.5 , c#, sql server2008,wcf,jquery,json,linq and Client-Side AJAX). my problem is that i want to build my project using the right architecture and i don't know how to do this? and should i use the design pattern too ?
So,I'm looking for online training that maybe help me to learn about the architecure and design pattern and how to use them in my website project?
I want to create a Online Exam site in ASP.NET .In that i want to display Test based on the Date and time and the user can take the test at the time set my the Teacher.
For Example:
Teacher want to take C Test for the Mid Semester Test and the test is schedule on 1 May 2010,then the test should appear on the test page on the 1st may only and the user should be able to take the test on the set time.
The problem is that if i use System time then user can change the system time and can take the test schedule in future.
So i want to know how can implement this thing.I have given many online test but dont know how they work out the time and date logic.
I want to make sure my theory of an upcoming project will work. Online ordering form for a restuarant. Order will be for pickup or delivery. no payment online. so gather order information and call web service which lives on a computer at the restaurant, this web service will log the order information into a file then send the order information to a ticket printer in the kitchen.
View 2 RepliesI need to build a page to test online video speed.
video will be uploaded in my webserver and there is no flash play in the server. I need to have two players. one is window media player, second is a flashplayer (prefer using google player)
Page layout:
Windows media player
report of speed testing
Flash player
report of speed testing
report requirement
1.length of video
2. total time that spend to load this video (dynamic is better)
3. average download and upload speed during playing the video
I am recently a layed off windows developer. It appears the only jobs available now are for web developers. I'm trying to learn this on my own but I think prospective employers might be more apt to hire a newbie if they have some accredited training.
Can anyone recommend some good online schools that have good asp.net training? I don't necessarily want another degree, just the training.
to find out online training or any kind of videos for WCF.
View 2 RepliesI am looking details on the internal working of asp.net architecture. The topics need to include the following:
Asp.Net Thread/Application Pools HttpRuntime HttpApplication - When and how it is set up How HttpContext is set up How objects can passed along the pipeline using HttpContext.Current.Items Why does modification of static variables requires locks in ASP.NET (advanced)IIS 7 Integration Mode
i want to create a centralised business or Service authendication architecture in .net. for example, we have a clients like c1, c2, c3, c4, ... etc. everybody logins seperatly as well as grouply. ie, if client "C1" logins [with login authentication] he can access c2 , c3, c4 also without login authendication. So its like a google. if we enters gmail account, we can access orkut, picasa like that.. i need the cetralised architecture.
And, client "c1" seperately asks seperately how will be the authendication architecture.
so give me the single solution for both these two scenarios. how will be the architecture for these two and how is the Data Base (Login) Structure.
recently i've studied on ADO.NET's Entity Model Framework and say 'wow' as ORM is one of the fevourite pattern i practice..but suddenly i've come to an ambiguous situation when i'm going to start. i usually follow the following 3-tier architecture..
1. UI Layer
2. BLL - business logic layer
3. DAL - Data Access Layer
a. DTO / DAO
b. Gateway (contains the sql query/stored procedure and connection with DB)
now when i'm going to use the Entity Model Design,where the DBML/ .edmx File should be placed? Because many a times i'm using the DBML file as DTO because of the mapped objects.. in the same time, sometimes DBML ( .edmx file in .NET 4.0) contains CRUD methods and stored procedured method as well as methods with different selection operations,- which should be in Gateway. so where the .edmx file should be placed !?!! IN DTO namespace !? or in Gateway namespace!
moreover sometimes there is no need for the BLL which breaks the rules of inter-layer-communication (UI > BLL > DAL.Gateway)! what makes me confuse is, what should be the ideal n-tier architecture when i'll use the ADO.NET Entity Model Design Framework
I am working on 3 tier architecture: UI, BL, DAL. In my UI i have following code for Asynchronous page processing:
[Code]....
But I want a database fetch operation to be performed in this asyncronous method. And due to 3 tier arch. i am unable to do this in UI Layer. Can anyone guide me that how can I implement Asynchronous processing in 3 tier architecture? Note: If you are going to place EndAsyncWork1 in DAL then show that how can I return a value back to UI layer from this function.
[Code]....
I want to know that What are the factors if we use methods on each .cs page for connection and executing query on each aspx code behind page rather then using BAL .
How our application get affected in terms of performance and speed or other way?
when we put our website on server after publish/compile in general approach (using query in C# code behind) rathor than using stored procedures?
then which logic is better and why ?
I have implemented the 3-tier architecture project; DAL, BAL, and presentation layer are three layers in it. I am going to implement the following scenario:
Presentation layer calls to a function in the BAL layer which returns 2 string variable, and in turn this function from BAL layer calls to a DAL layer function which also returns 2 string variable. How can I implement the above scenario?
I'm developing a n-tier architecture... I'm confused with handling exception in the layers... Is it a good practise to add a Exception Layer to the architecture.
View 3 RepliesI am a newbie to asp.net and work in a firm where the projects are quite small.
I was told by my manager that in a few weeks or so we would be getting a bigger project and I need to be well versed with Design Patterns and N tier arcihtecture.
I would really appreciate if someone could provide me some links and also drop me a few sentences on how this things are useful?
I am going to create the SAAS (Software as a service) Application. Can you please provide all the attributes that we have to consider in SAAS application (for example usability, pluggable architecture etc .. )
How architecture should be build for this project, provide sample architecture for SAAS application. This architecture should be easy to upload and upgrade or degrade the features. Error handling should be easy.
I am try to create architecture design for WCF service.
We have WCF service that we have to expose to third party so then can request with xml and get back xml response.
The wcf service should do the following:
- Accept the request call with xml
- Check xml against the schema
- Parse the xml
- Authenticate the incoming xml by username and password that will be in xml
- Send back the response
If anybody can let me know what kind of design I can use or is there any pattern available that I can take it and then extend it as per my requirement.

View 3 Replieshey folks I got a general question that maybe some of you can just weigh in. I developed an online store for a client and people place orders online for a food ordering place however I am trying to find the best way to have the orders show up for them at the store. Currently I am sending an email and an autoprint software prints it out which works most of the time but not good enough sometimes it doesn't print. Anyone had similar issues or have other alternative solutions you may have heard off? Like I said the site sends an email to the customer and the store's email account.

View 2 RepliesI was tasked to create 3 tier web application. However, i browsed through many books & tutorials. The examples are doing it using Object data source which my lecturers claimed that it is not 3 tier at all. Shouldn't be dragging any data source into deisgn view. Any comprehensive examples for me to take reference from?
View 4 Repliesi want to develop an application in asp.net using 3 tier architecture .
i know that there are three layers
Data layerBusiness Layer
Data Access LayerBusiness Logic Layer Presentation Layer. I am confused between Data Access Layer and Business Logic Layer.
In data access layer we develop the property classes and main class function which returns datasets, datatables and data reader to Presentation layer.
what is the use of Business Logic Layer ? what actually we do in Business logic Layer
?? we can pass data directly from data access layer to presentation layer ?
i am in the process of creating 3 tier architecture for ASP.net with Microsoft Studio 2005.
My architerture is as below

I have 2 question here:
(1).MSDN say that we should not have the namespace where its name is same with class name but it does not exlpain why.Does anyone know why? The msdn page is
http://msdn.microsoft.com/en-us/library/893ke618%28VS.71%29.aspx
(2). Business Logic Layer BLTable1 need to interact with Data Access Layer
DaTable1 , so i put the code: imports MyCompany.MyProject.DA. DaTable1 inside
BLTable1, so that i can have access to all the public shared method inside
DaTable1 in BLTable1 for example : DaTable1.Save()
But problem arise when BLTable1 want to use the public shared method in BLTable2 .
I have put the code imports MyCompany.MyProject.BL. BLTable2 inside BLTable1,but i need to
key in the class name twice only can access to the public shared method inside
BLTable2 for example :BLTable2.BLTable2.Save.
