Im in the process of building an Enterprise Application, I want to have the DAL & BLL in separate projects, one each. With a structure like this, what should i do with the Models folder in MVC'S Default Project?
View 3 RepliesI'm designing an enterprise web application interface based on an old system, and i planned to migrate the old frames layout to master page, but i noticed that if i use masterpages, the application users will be able to see the querystring or route path, and it could be a security issue. What is the best way to avoid this? Using frames? Masterpages with iframes as content? Masterpages with all PartialViews loaded by jquery?

View 3 RepliesI found a great control with example here for mvc It fulfills all my requirement but the problem is that it uses a js tree dll. Should I go on and used that example in my application? Do you people refrain from using 3rd party free dll in applications? How will I tell that it will not expire or not cause problem later on Forgive me if this is inappropriate question but thx in advance for any appropiate reply on this topic. just trying to get the point of view of you people on this
View 1 RepliesWe have a huge ASP.NET web application which needs to be deployed to LIVE with zero or nearly zero downtime. Let me point out that I've read the following question/answers but unfortunately it doesn't solve our problems as our architecture is a little bit more complicated.
Let's say that currently we have two IIS servers responding to requests and both are connected to the same MSSQL server. The solution seems like a piece of cake but it isn't because of the major schema changes we have to apply from time to time. Because of it's huge size, a simple database backup takes around 8 minutes which has become unacceptable, but it is a must before every new deploy for security reasons.
Currently the best idea we came up is buying another SQL server which would be set up as a replica of the original DB. From the load balancer we would route all new traffic to one of the two IIS webservers. When the second webserver is free of running sessions then we can make deploy the new code. Now comes the hard part. At this point we would go offline with the website, take down the replication between the two SQL servers so we directly have a snapshot of the database in a hopefully consistent state (saves us 7.5 of the 8 minutes). Finally we would update the database schema on the main SQL server, and route all traffic via the updated webserver while we are upgrading the second webserver to the new version.
also share your thoughts regarding this solution. Can we somehow manage to eliminate the need for going offline with the website? How do bluechip companies with mammuth web applications do deployment?
Edit 1 (2010.01.12):
Another requirement is to eliminate manual intervention, so in fact we are looking for a way which can be applied in an automated way.
Let me just remind you the requirement list:
1. Backup of database
2a. Deploy of website
2b. Update of database schema
3. Change to updated website
4 (optional): easy way of reverting to the old website if something goes very wrong.

I have my validation configuration stored in validation.config in my Business Object project. The config file is set to copy if newer

I've recently taken an existing ASP.NET 3.5 web forms application that was upgraded to .NET 4 last year (and has been running fine) and configured it to also run ASP.NET MVC3 following Scott Hanselman's blog post: Integrating ASP.NET MVC 3 into existing upgraded ASP.NET 4 Web Forms applications. It works well and I've successfully begun to introduce views based on Razor and the existing aspx pages continue to work.
The one thing that has stopped working, however, is a custom HttpHandler (our load balancer hits a specific address to ensure the application is available - the handler is for that address). The web.config has always declared the handler in the system.web section like this:
<httpHandlers>
<add verb="*" path="system/heartbeat.aspx"
type="My.Monitor.HttpHandlers.LoadBalancerHandler, My.Monitor"/>
</httpHandlers>
Now we're testing post-MVC3 and I'm getting an exception that reads:
The controller for path '/system/heartbeat.aspx' was not found or does not implement IController. I have defined a RegisterRoutes method in my Global.asax and that method is called from the Application_Start. Within RegisterRoutes I've got the IgnoreRoute declarations from Hanselman's blog:
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.IgnoreRoute("{resource}.aspx/{*pathInfo}");
which I thought was to prevent the Routing system from taking anything with an extension of .aspx. I can reproduce the issue in VS2010 as I debug, and the deployment environment is running IIS 6. What can I do to prevent the Routing system from trying to handle that address so the custom handler can do it's thing?
I just made my first MVC3 app, and I thought it would be fun to upload it to my web hotell. So I did a publish locally in visual studio and then transfered the published files to them over ftp. They have support for MVC3, so there shouldn't be any problems there. But what I get when I try to go the the page I get an 403 - Forbidden: Access is denied
I've tried to add the:

View 1 RepliesWe have a big classic ASP website, and we want to start writing new code in .net, (the website is way to big to rewrite 100% at this stage).
The old website uses session variables, will these still be accessible in the .net pages, and if not (which I suspect) is there anything we can do to make them accessible?
The new section is detachable, that is it is pretty much independent from the rest of the site so should be fine to write in .NET, it's just sessions which are important to us. Do we need another login page?
How bad practise would it be to ajax a local .net page which sets session info when they login to the old site? Can we copy session data this way?
I am looking to build a web application from the ground up. I have done a bit of research, however I just thought I would post here to see what kind of responses I get. I will give a brief description of the type of application I am trying to build. It will be a database web app for managing clients and financials of those clients. The application will need a secure log on system for approximately 160 end users, with the ability to change permissions for each user given their individual rights.
Depending on the type of user created they will have access to 1 of 7 unique application modules within the app framework. A data dictionary will be designed and created prior to starting the project as the 7 unique application modules will have common database fields and custom relationships. Based on this information, what asp.net tools, libraries or books would you recommend using?
I am building an application where I need to check/send a query to database every second. So, is there any way to do that??

How this is being done? Is this page is created while adding product itself?
I need to build a globalized web application, and I already have those resource files in the App_GlobalResources folder. My web application is built upon an N-tier architecture: DAL, BLL and Presentation are the layers, and we are using SQL Server 2008. We have decided that the database, BLL and DAL will always be operating using the en-US culture, but the culture in the Presentation layer can vary.
ASP.NET works with two culture properties: Culture and UICulture. There's an article in MSDN that states that a thread's UICulture determines which resource files ASP.NET picks, and Culture determines datetime/currency formating, etc.
So, to have a fully globalized application, I think I must set both Culture and UICulture, so that both Resources and datetime/currency formating are displayed using the same culture.
Then I thought I would set those culture properties (both of them) in the BeginRequest event in my web application, based on the user's choice, and that everytime a method in the BLL is called, it sets the thread's Culture property to "en-US" and, just before it returns, it sets the thread's Culture back to what it was before.
I'm building an Iphone application, which has to retrieve information from a database on a server.
I thought about building a C# web service on the server,so the Iphone app will send a http request to the web service and get the required data as a xml output. Are there any better alternatives? for instance: I never tried but heard about WCF, maybe it's better using it instead of the older xml web service technology?

i think this website is developed in flash with actionscript.I dont want to use Silverlight or Flash . what are the other options i have?
My new office project is based on an MVP design and is in VB.NET (.NET 3.5), using multiple libraries (like EntLib, internal corporate framework, etc.). The number of DLLs used as references is so huge (almost 50) that when I try to build/debug the application in VS2008, it takes almost 3-4 minutes to get the website running successfully.Wanted to know if there are any settings/areas which upon some modifications can help me reduce the build time? and what exactly can be the major reasons behind this long loading duration?

View 2 RepliesI am using Enterprise library for my data access. when I am running the application, at the CreateDatabase() statement I am getting this exception:
Microsoft.Practices.ObjectBuilder2.BuildFailedException was unhandled by user code Message="The current build operation (build key Build Key[Microsoft.Practices.EnterpriseLibrary.Data.Database, null]) failed: The value can not be null or an empty string. (Strategy type Microsoft.Practices.EnterpriseLibrary.Common.Configuration.ObjectBuilder.ConfiguredObjectStrategy,index 2)" Source="Microsoft.Practices.ObjectBuilder2"
Now, I googled a bit and I found that I have to place
<dataConfiguration defaultDatabase="LocalSqlServer"/>
but I don't know where. Is it the right solution? Also, at the time of installing enterprise library I didn't see any connection string statement? So, I wonder how it will take the connection string from web.config file. In the connection string section of my web.config file I have:
<remove name="LocalSqlServer"/>
<add name="LocalSqlServer" connectionString="Data Source=MSTR;Initial Catalog=USERDb;Integrated Security=true;" providerName="System.Data.SqlClient"/>
I wanted to get any feedback (put out a feeler) for how the enterprise library plays with linq-to-sql generated classes. I was considering using the validation handler to provide validation logic/display to the UI level. I am considering the caching handler, validation, and authorization handlers primarily.
View 1 Replies I have a question about validation. Basically how the MVC framework is setup it can use DataAnnotations. It calls TryValidate in a controller which does some other black magic, and poof, you have a ModelState with validation results. Now to extend this validation you can create a validator and then provide custom validation on both server and client side. Here is the problem... what if you dont want to hard code all of the validation in the classes? I would like to use what Microsoft has already provided in the Enterprise Library [URL]for validation. I will be using both DataAnnotations and configured rule sets. Of course I could just put the code in each action, but that is so 1999. As I see it the MVC framework falls short by not allowing us to use the config for such things. Why is the validation so specific for MVC? Why could it now have used the Enterprise Validation? I wrote my own abstract controller and put in Enterprise Library validation and it worked GREAT!!! So why am I here? Well, surly there must be a better way... do I really have to write my own controller abstract class to change the validation?
So if you think you know how to solve this problem, you must provide a solution that does this:
Uses DataAnnotations AND Configuration RulesCan validate the SAME in a console application (could really be any non-web app) and MVCI do see that MVC 3 adds a little more support for validation which was really needed. It supports IValidatableObject, which allows you to validate the whole Model... its nice, but now we have 3 ways to do that same thing... granted the former 2 (DataAnnotation on the class, and a Validator for the DataAnnotation) could not pass the error to the correct place in the view. Now if we could just support all of this validation in a place what any type of application could use it. In my use case I will run validation on the MVC app, perhaps some other apps, and on an ESB.
I'm trying to learn the Enterprise Library. I found this useful code sample to get data from a SQL database. But I tried to send data via a parameter. I'm also using the UPDATE, DELETE, and SAVE methods. Can you give me a similar sample? I'm using Enterprise Library 4.0.
