View 10 RepliesArchitecture :: What Basically Is Factory Design Pattern
Jul 17, 2010I visited this Link to study about Factory design pattern.http://wiki.asp.net/page.aspx/310/factory/ But i am confused about it still. What i understood is that we must use an Interface to define a class .In the interface we will give the prototype of functions and later on we will define it in concrete class. Is that simple concept is Factory design pattern ?
View 13 RepliesArchitecture :: Factory Patterns Implemented In .Net Framework?
May 17, 2010I am having troubles understanding the purposes of using Factory pattern, I understand Factory pattern uses Factory class that has methods to return concrete objects. But why don't I simply use new opertor to create concrete objects? Some articles suggest Factory methods could return objects of different concreate classes, I can do the same thing by using switch statement.
Also are there classes in .Net framework already implementing Factory pattern? I think that will give me a better ideas why it is useful.
WCF / ASMX :: Any Examples For Consuming Web Service Method By XML Parameters Using MVC?
Jan 18, 2011For example, we are going to consume web method GetEmployeeByQuery(ConnInfoXML, Query, RecordDetail), ConnInfoXML is login information in XML, Query is a SQL statement selecting records, RecordDetail is all records retrieved. All data are in XML format.
So how to write these parameters in XML to consume this web method and get all the information in XML, and then transfer XML to normal string format ?
Architecture :: How To Design A Centralized Business Or Service Authentication Architecture
Sep 22, 2010i 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.

Architecture :: Create architecture design For WCF Service?
Aug 10, 2010I 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.
Architecture :: WCF Service Be Used To Receive Data As Needed From A Remote Sender Or Service?
Feb 25, 2011I am not sure which approach I should use. I have a web application that needs to get/receive data from a third party application that is in a secure remote network. The data needs to be secure during transport. The data layers cannot be exposed and the databases will not talk to each other. The data will be received from remote application on demand, or will get at scheduled intervals.
I have looked at WCF, but not sure if this will work. Can a WCF service be used to receive data as needed from a remote sender or service? Is this a secure way of doing it? I have also looked at SFTP using some XML/XSLT, but I don't think this is the right way to go. In addition, some data may be transported from my web application to the remote application (mostly reports at first). What protocols are used to transfer data between HIPAA compliant applications?
Architecture :: DAL As Web Service - Adding A Service Reference To Project And Then Using The EF4 Context And Writing LINQ Queries Against The DB?
Feb 10, 2011I'm currently trying to work out the best way to build this web application, which will then be intergrated on other systems, such as WinForms, Intranets etc.
We hope to include the usual layers i.e. DAL, BLL, BOL and UI but I have been experimenting with Entity Framework 4 and WCF Data Services and managed to get something in place where I was using WCF as a gateway to EF4.
i.e. Adding a Service Reference to my project and then using the EF4 context and writing LINQ queries against the DB
e.g.[Code]....
Now with the current setup I would still need to write a DAL Class Library, that interacts with the Data Service, because as I said WCF Data Services only seems to be a gateway, I can't see where to put the code (above) in the Data Service and then how I could these methods.
My questions are: 1. How do I develop a WCF Data Service in such a way to allow this behaviour - I know how I could do it using ASMX web service, something like [Code]....
2. If I am to use WCF Data Services, how is serialization handled (if at all) - again I know how to do something in ASMX web services
3. Again, If I am to use WCF, how do I add Security and only allow my applications to access the web service - for obvious reasons
4. Would it be possible / logical to also include the Business Logic Layer into the web service?
Architecture :: Using Windows Service In Web Application?
Sep 10, 2010I wanna embed the windows service in the web application. I have seen few posts in the web. where they generate separate exe for the windows service and use it as an installable.
The same process i tried doing it but it threw an OS error in my server which is windows 2000 and didnt supported the executable.
However the website of mine runs fine in the same server. Thus i was thinking if i cd embed the same code in the web application.
Also, in my case the website of mine takes job for simulation. These jobs are taken for simulation execution and nearly takes 12hrs for completion and if they are not completed within twelve hours then they are supplied extra twelve hours to complete the simulation jobs.
The simulation executables are a series of executable and bat files.
The results of the simulation gets updated in the tables of MySql and hence are displayed to the user.

View 11 RepliesArchitecture :: Validation, Service Layers And Testing?
Dec 23, 2010I have a quick question in regards to testing my validation. I have been looking through a few MVC examples and have noticed the 'Validating with a Service Layer' tutorial which is pretty nice. It discusses how to abstract your code out etc..My question is, that they have validation occuring in the service layer, if errors occur, the error + message then gets added to a model state dictionary.Now i want to test my model to make sure my business rules are being applied to it, but with this approach, for starters, the Validation method is not in the interface. Now, if the validation method was in the interface, during testing you would have to re-implement the validation on the testing side.Am i missing somthing? Where should your validation code go? I feel like it should go in the model, but then i have to track the errors on the model side.
View 1 RepliesArchitecture :: Web Service - File Download With MTOM?
Jan 18, 2011I have a web service I put together that has a custom soap header for the authorization (UserName and Password).I have a function currently that will allow a user to download a file from my site via a web service.I have integrated this download to the membership system of the site.They are using a vb.net front end client to perform the download.The files I download are around a meg in size.I would like to show the download progess of the file.I was going to setup MTOM and download the file in chunks.I am trying to get around the authorization of each "chunk" of data that I am sending down to the client.I do not want to hit my authorization process for all of these calls to the web service with the file offset.The authorization header works well for other functions I have put together for this web service.
They set a username and password and then call a function for specific data that I am making available via the web service.Is there an easier method to stream a file to a user and show the download progress of the file?I was going to generate a token and have that token passed per chunk,but I still have to go through my security process.Can anyone assist in the proper design of a webservice to stream a file with progress and passing credientials.

View 3 RepliesC# - How To Start With Entity Framework And Service Oriented Architecture
May 12, 2010At work I need to create a new web application, that will connect to an MySql Database.
(So far I only have expercience with Linq-To-Sql classes and MSSQL servers.)
My superior tells me to use the entity framework (he probably refers to Linq-To-Entity) and provide everything as a service based architecture. Unfortunately nobody at work has experience with that framework nor with a real nice server oriented architecture. This speficic project I'm leading will be long-term, meaning multiple years, so it would be best to design it the way, that multiple target plattforms like asp.net, c# wpf, ... could use it)For now, the main target plattform is ASP.net
So I do have the following questions:
1) Where can I read best what's really behind service oriented architecture (but for now beginner tutorials work fine as well) and how to use it in best practise?
2) So far I can't see a real difference between Linq-To-Sql classes and the information I've googled so far on the 'entity framework'. So, whats the difference? Where do I find nice tutorials for it?
3) Is there any difference in the entity framework regarding the database server (MSSQL or MySQL)? If not, does that mean that code snipperts I will stumble across will word database independent?
Architecture :: Using .asmx (web Service) Files Locally Within Web App As The Datasource?
Jan 5, 2011I have been wrestling with web services technology/techniques for part of 2010 - learning how to reate/consume/deploy... I have also been experimenting with third party web controls from ComponentArt. In some of the samples from ComponentArt I observed that they use .asmx files locally to populate their custom data controls (datagrids, comboboxes, treeview controls...). What is interesting (and a little bit confusing to me) is that in the ComponentArt samples they reference the web services directly within their controls in the markup. My question is if this can be done normally with controls that ship with Visual Studio (any version -- I have em all 2005, 2008, 2010). I ask this question because from VS I only know to reference web services by right clicking on the project in the solution explorer to add a web reference.
Here is the services tag used by ComponentArt
<Services>
<asp:ServiceReference path="FileExplorerTreeViewService.asmx" />
</Services>
Then in the property grid of a data control -- say a treeview control-- they reference the web service, and when the project is run -- the control is populated with data from the web service.
Do data controls from VS support this technique? My other question is if there is a benefit to using a web service as a datasource for a control and what is this benefit? What is the criteria for using a web service in this manner?

May 3, 2010I have an Interface that has its concrete class defined via a factory. Because of this I found no way to use the Interface tpye directly in my LINQ quesry so I had to use the concrete class types to creat a generic list. The LINQ query works but after calling.ToList() on the LINQ query result I get a List(of MyConcreteClass), but I need a List(of IMyConcreteClass). I have tried everything I can find: .Cast, Ctype, implicit casting, etc. but I always get back one of the (2) messages (depending on if I attempt to cast)message:
"Unable to cast object of type 'System.Collections.Generic.List`1[MyConcreteClass]' to type 'System.Collections.Generic.IEnumerable`1[IMyConcreteClass]'."
