  • I'm creating my own scalable, rapid prototyping web server. How should I design it?

    - by Mike Willliams
    I'm going to create my own web server that focuses on scalability, rapid prototyping and the use of JavaScript as the server's scripting language, much like node.js. It will use a Model-View-Controller design pattern so a web application can support more concurrent users just by adding hardware -- and not having to redesign the software. Basically, I'm aiming to produce a framework that allows for fast and easy development of cloud applications without the need to write lots of boiler plate code. I've got some questions about this... How hard will it be to put MySQL in the cloud? How could I go about implementing this and make the resulting product free? Will I have to write my own engine or modify an existing one, if I do what should I watch out for? To make this scalable I need to adjust from one server to hundreds of servers this creates the requirement for the servers to be load balancing, how should I do this? If I balance based on the work load per server I would need gateway to handle all the incoming requests. Is it the right idea to have all the servers check into the gateway and update there status. By having the servers run through a gateway if the gateway dies all the incoming requests are ignored. I'm thinking that having all the servers maintain a list of each other, or at least a few I could rebuild the list of servers and establish a new gateway. Is it worth it? Or should I have a backup gateway that could switch out? Should I let the user choose? How should I pick which server handles the database and which handles the page serving? Should I spread the database so that queries are preformed on multiple servers? Which would theoretically improve performance. The servers would need to mirror the database at least once so that if a server goes down the database isn't corrupted. So this brings up writing another question, should I broadcast SQL queries so that all the servers can take a bit of the work load? If I do it that way wouldn't a query clog up the network so that other queries couldn't be preformed? What are my alternatives? Finally, is there a free solution already out there that might need a little modification that suits my needs?

  • Weird - "The EntityReference object could not be serialized" when serializing from an ASP.NET Web Si

    - by Mikey Cee
    I have an Entity Framework data model. Part of the model is a Customer entity. The web service provides a method to get a customer, and to receive an updated version of this customer to be persisted. To test this, I created a new ASP.NET web Application, (Solution Add New Project ASP.NET Web Application), then added a reference to my service reference using the standard Add Service Reference dialog. I then call the service using the following code: var client = new CustomerServiceClient(); var customer = client.GetCustomerByID(18); // get it customer.LimitDown = 100; // change it client.SaveCustomer(customer); // persist it Everything works as expected. Now, I do exactly the same thing, but this time with as ASP.NET Web Site (Solution Add New Web Site ASP.NET Web Site). I add the reference in a similar fashion and copy and paste the code above into the new site. But now I get the following exception thrown on the 4th line: System.InvalidOperationException The EntityReference object could not be serialized. This type of object cannot be serialized when the RelationshipManager belongs to an entity object that does not implement IEntityWithRelationships. Source Error: Line 2474: Line 2475: public SkyWalkerCustomerService.OperationResult SaveCustomer(SkyWalkerCustomerService.Customer customer) { Line 2476: return base.Channel.SaveCustomer(customer); Line 2477: } Line 2478: } Stack Trace: System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage(IMessage reqMsg, IMessage retMsg) +9475203 System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData& msgData, Int32 type) +345 SkyWalkerCustomerService.ICustomerService.SaveCustomer(Customer customer) +0 SkyWalkerCustomerService.CustomerServiceClient.SaveCustomer(Customer customer) in c:\Windows\Microsoft.NET\Framework\v4.0.30128\Temporary ASP.NET Files\testsite2\dd2bcf8d\f95604ff\App_WebReferences.fz4h7x7l.0.cs:2476 _Default.Page_Load(Object sender, EventArgs e) in c:\Users\Mike\Documents\Repositories\UWC\SkyWalker\TestSite2\Default.aspx.cs:17 System.Web.Util.CalliHelper.EventArgFunctionCaller(IntPtr fp, Object o, Object t, EventArgs e) +14 System.Web.Util.CalliEventHandlerDelegateProxy.Callback(Object sender, EventArgs e) +35 System.Web.UI.Control.OnLoad(EventArgs e) +91 System.Web.UI.Control.LoadRecursive() +61 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1966 Googling for this error returns very little.

  • Why is "Fixup" needed for Persistence Ignorant POCO's in EF 4?

    - by Eric J.
    One of the much-anticipated features of Entity Framework 4 is the ability to use POCO (Plain Old CLR Objects) in a Persistence Ignorant manner (i.e. they don't "know" that they are being persisted with Entity Framework vs. some other mechanism). I'm trying to wrap my head around why it's necessary to perform association fixups and use FixupCollection in my "plain" business object. That requirement seems to imply that the business object can't be completely ignorant of the persistence mechanism after all (in fact the word "fixup" sounds like something needs to be fixed/altered to work with the chosen persistence mechanism). Specifically I'm referring to the Association Fixup region that's generated by the ADO.NET POCO Entity Generator, e.g.: #region Association Fixup private void FixupImportFile(ImportFile previousValue) { if (previousValue != null && previousValue.Participants.Contains(this)) { previousValue.Participants.Remove(this); } if (ImportFile != null) { if (!ImportFile.Participants.Contains(this)) { ImportFile.Participants.Add(this); } if (ImportFileId != ImportFile.Id) { ImportFileId = ImportFile.Id; } } } #endregion as well as the use of FixupCollection. Other common persistence-ignorant ORMs don't have similar restrictions. Is this due to fundamental design decisions in EF? Is some level of non-ignorance here to stay even in later versions of EF? Is there a clever way to hide this persistence dependency from the POCO developer? How does this work out in practice, end-to-end? For example, I understand support was only recently added for ObservableCollection (which is needed for Silverlight and WPF). Are there gotchas in other software layers from the design requirements of EF-compatible POCO objects?

  • EF4 Generate Database

    - by shaneseaton
    Hi, I am trying my hardest to find the simplest way to create a basic "model first" entity framework example. However I am struggling with the actually generation of the database, particularly the running of the SQL against the database. Tools Visual Studio 2010 SQL Server 2008 Express Process Create a new class project Add a new Server-Database item (mdf) named "Database1.mdf" to the project Add an empty ADO.net Entity Model Create a simple entity (Person: Id, Name) Generate the Script selecting the Database1 connection created for me by visual studio Right click the script editor and select the "Execute SQL..." option Log in to SQLEXPRESS This is where is falls over saying it cant find a database name "Database1". The "problem" is that the SQL server has not had Database1 attached to it. I am 100% positive that Visual Studio use to attach a database to SQLExpress when it created a new database (Step 2). This appears to not be the case any more (even the beta of VS2010 did it). Can someone confirm this? or tell me how to get this to happen? Is there a way that I can modify the TSQL script to use an un-attached database. ie a file. I know I can use SQL Management Studio or sqlcmd to attach the database, but I would ideally like to avoid the solutions as I would like to see the cleanest method of just using visual studio. Ideal Solutions (in order of most prefered) Get visual studio to attach the newly created database Modify the generated SQL to point to file Thanks in advance.

  • using Autofac in a multi-layered architecture

    - by Kamyar
    I'm fairly new to the DI/IoC concept and would like to use Autofac in a 3-layered ASP.NET Webforms application. UI layer: An ASP.NET webforms website. BLL: Business logic layer which calls the repositories on DAL. DAL: .EDMX file (Entity Model) and ObjectContext with Repository classes which abstract the CRUD operations for each entity. Entities: The POCO Entities. Persistence Ignorant. Generated by Microsoft's ADO.Net POCO Entity Generator. I have asked a more general question here. Basically, I'd like to create an obejctcontext per HttpContext in my DAL. But i don't want to add a reference to DAL in UI or access to HttpContext in DAL directly. I guess this is where IoC tools come to play. The answer to my previous question is a very good example of using Windsor Castle. I'd like to use Autofac as my IoC tool and Don't know how to achieve this. (How to access DAL in application_start to register the component while I don't want to reference it in my UI, what are the proper references to be able to use DAL component in BLL with Autofac, Should I register BLL as a component with Autofac too) Sorry folks for not providing an explicit question and requesting a kind of working example, But I'm very unfamiliar to the whole IoC concept and I don't think I can achieve it to use in my current time-limited project.

  • How to fluent-map this (using fluent nhibernate)?

    - by vikasde
    I have two tables in my database "Styles" and "BannedStyles". They have a reference via the ItemNo. Now styles can be banned per store. So if style x is banned at store Y then its very possible that its not banned at store Z or vice verse. What is the best way now to map this to a single entity? Should I be mapping this to a single entity? My Style entity looks like this: public class Style { public virtual int ItemNo { get; set;} public virtual string SKU { get; set; } public virtual string StyleName { get; set; } public virtual string Description { get; set; } public virtual Store Store { get; set; } public virtual bool IsEntireStyleBanned { get; set; } }

  • How to use the LINQ where expression?

    - by NullReference
    I'm implementing the service \ repository pattern in a new project. I've got a base interface that looks like this. Everything works great until I need to use the GetMany method. I'm just not sure how to pass a LINQ expression into the GetMany method. For example how would I simply sort a list of objects of type name? nameRepository.GetMany( ? ) public interface IRepository<T> where T : class { void Add(T entity); void Update(T entity); void Delete(T entity); void Delete(Expression<Func<T, bool>> where); T GetById(long Id); T GetById(string Id); T Get(Expression<Func<T, bool>> where); IEnumerable<T> GetAll(); IEnumerable<T> GetMany(Expression<Func<T, bool>> where); } public virtual IEnumerable<T> GetMany(Expression<Func<T, bool>> where) { return dbset.Where(where).ToList(); }

  • Organizing Eager Queries in an ObjectContext

    - by Nix
    I am messing around with Entity Framework 3.5 SP1 and I am trying to find a cleaner way to do the below. I have an EF model and I am adding some Eager Loaded entities and i want them all to reside in the "Eager" property in the context. We originally were just changing the entity set name, but it seems a lot cleaner to just use a property, and keep the entity set name in tact. Example: Context - EntityType - AnotherType - Eager (all of these would have .Includes to pull in all assoc. tables) - EntityType - AnotherType Currently I am using composition but I feel like there is an easier way to do what I want. namespace Entities{ public partial class TestObjectContext { EagerExtensions Eager { get;set;} public TestObjectContext(){ Eager = new EagerExtensions (this); } } public partial class EagerExtensions { TestObjectContext context; public EagerExtensions(TestObjectContext _context){ context = _context; } public IQueryable<TestEntity> TestEntity { get { return context.TestEntity .Include("TestEntityType") .Include("Test.Attached.AttachedType") .AsQueryable(); } } } } public class Tester{ public void ShowHowIWantIt(){ TestObjectContext context= new TestObjectContext(); var query = from a in context.Eager.TestEntity select a; } }

  • How can I have 2 ADO access methods use the same Transaction?

    - by KevinDeus
    I'm writing a test to see if my LINQ to Entity statement works.. I'll be using this for others if I can get this concept going.. my intention here is to INSERT a record with ADO, then verify it can be queried with LINQ, and then ROLLBACK the whole thing at the end. I'm using ADO to insert because I don't want to use the object or the entity model that I am testing. I figure that a plain ADO INSERT should do fine. problem is.. they both use different types of connections. is it possible to have these 2 different data access methods use the same TRANSACTION so I can roll it back?? _conn = new SqlConnection(_connectionString); _conn.Open(); _trans = _conn.BeginTransaction(); var x = new SqlCommand("INSERT INTO Table1(ID, LastName, FirstName, DateOfBirth) values('127', 'test2', 'user', '2-12-1939');", _conn); x.ExecuteNonQuery(); //So far, so good. Adding a record to the table. //at this point, we need to do **_trans.Commit()** here because our Entity code can't use the same connection. Then I have to manually delete in the TestHarness.TearDown.. I'd like to eliminate this step //(this code is in another object, I'll include it for brevity. Imagine that I passed the connection in) //check to see if it is there using (var ctx = new XEntities(_conn)) //can't do this.. _conn is not an EntityConnection! { var retVal = (from m in ctx.Table1 where m.first_name == "test2" where m.last_name == "user" where m.Date_of_Birth == "2-12-1939" where m.ID == 127 select m).FirstOrDefault(); return (retVal != null); } //Do test.. Assert.BlahBlah(); _trans.Rollback();

  • Mapping one column in a table to multiple tables

    - by user1721814
    I am working on a new product development creating a WMS system. I have done it in past using ASP, VB, and other techniques where we did not hard code the mapping. But now i am working on it using MVC and entity frame work and i am stumped. How can i map one column in transaction table to a column in multiple tables. I have transaction table trans Transid orderref TType productid qty ....(More Columns) now the orderref will hold either Receiptkey, orderkey , movementkey, adjustmentkey and the TType column will tell me which type of transaction i am dealing with and based on that i would know which table to link further. Now how can i achieve this in Entity Frame work. This is the most important step. I have done this many times in my other languages but now using EF i am stuck. Please help. I have checked a lot online but i have not found it. I am new to MVC and entity frame work architecture. Any guidance would be highly appreciated. Ranjit

  • Do I have to implement Add/Delete methods in my NHibernate entities ?

    - by Lisa
    This is a sample from the Fluent NHibernate website: Compared to the Entitiy Framework I have ADD methods in my POCO in this code sample using NHibernate. With the EF I did context.Add or context.AddObject etc... the context had the methods to put one entity into the others entity collection! Do I really have to implement Add/Delete/Update methods (I do not mean the real database CRUD operations!) in a NHibernate entity ? public class Store { public virtual int Id { get; private set; } public virtual string Name { get; set; } public virtual IList<Product> Products { get; set; } public virtual IList<Employee> Staff { get; set; } public Store() { Products = new List<Product>(); Staff = new List<Employee>(); } public virtual void AddProduct(Product product) { product.StoresStockedIn.Add(this); Products.Add(product); } public virtual void AddEmployee(Employee employee) { employee.Store = this; Staff.Add(employee); } }

  • How to use different providers for Linq to entities?

    - by Anders Svensson
    I'm trying to familiarize myself a bit more with database programming, and I'm looking at different ways of creating a data access layer for applications. I've tried out a few ways but there is such a jungle of different database technologies that I don't know what to learn. For instance I've tried using datasets with tableadapters. Using that I am able to switch data provider rather easily (by programming against the interfaces such as IDbConnection). This is one thing I would want to achieve. But I also know everyone's talking about LINQ, and I'm trying to get to know that a bit better too. So I have tried using Linq to Sql classes as the data access layer as well, but apparently this is not provider independent (works only for SQL Server). So then I read about the Entity Framework (which just as Linq to SQL apparently has gotten its share of bashing already...). It's supposed to be provider independent everybody says, but how? I tried out a tutorial to create an entity data model, but the only providers to choose from were SQL Server/Express. Just for learning purposes, I would like to know how to use the entity framework with MS Access/OleDb. Also, I would appreciate some input on what is the preferred database technology for data access. Is it LINQ still after all the bashing, or should you just use datasets because they are provider independent? Any pointers for what to learn would be great, because it's just too much to learn it all if I'm not going to use it in the end...!

    Lets say I have Spring Framework App that is running on Tomcat and uses MySQL database: What would be the best solution in this instance that would allow for sociability (price/performance/integration time)? More precisely: What would be on the Web Load balancer box, and who should be the tomcat web server clustered? What would be on the Database Load balancer box and how should be the database servers clustered? And if at all possible specific technical integration links would be of great help.

  • Trouble getting PHP, Apache, and Zend talking to eachother (localhost)

    - by Joel
    Hi guys, I've searched through several other questions, but haven't found my solution. THe main reason is that I'm not even sure if I have all these things properly installed. I have a hosting account, and have always just deployed everything into the internets, but I'm finally trying to figure out how to get my desktop set up right for learning Zend Framework. I have Apache Server 2.2, PHP, And Zend Framework installed. I'm trying to do this tutorial: http://akrabat.com/wp-content/uploads/Getting-Started-with-Zend-Framework.pdf The problem is when I click on the link: http://localhost/zf-tutorial/public I get an Error 404. If I type in http://www.localhost I get "It Works!" in the browser. I'm thinking this means I have Apache installed correctly, but am not pointing correctly to the Zend tutorial? Thanks for any help!

  • Visual Studio compiles WPF application twice during build

    I have a WPF app in VS2008 that compiles twice during the build. The two CSC command lines are similar but with some differences.

However, when I go to %WINDIR%\assembly folder I cannot find the assembly I installed using the .NET Framework 4.0 gacutil. I've seen some posts saying the .NET Framework 4.0 has a separated GAC, but what I haven't found was where it is located. May someone to help me to check where can I see the Global Assembly Cache of .NET Framework, as it used to work on previous version (%WINDIR%\assembly)?

  • Slow SQL Sync with Microsoft Sync Framework on Mobile Client

    - by Malkier
    Hello, we are developing an application which uses MS Sync Framework to sync data between Windows CE 6.0 with SQL CE 3.5 SP1 Clients and an SQL 2008 Database. Our major problem is a slow sync time up to 1 minute for 15 tables which are totally empty. Here's a break down of our components: Server: Sql Server 2008 15 tables with activated change tracking WCF Service with endpoint for the mobile sync (uses Sync Framework 2.0) Client (Mobile) Windows CE 6.0 NET Application using Sync Framework for Devices (CTP 1) which starts the sync As I mentioned above, the sync takes up to 1 minute without any changes and empty tables. The mobile device is in its dock. This is a deal breaker for a production environment. Does anybody have any experience in this field? Is there a way to improve things? Thanks for any responses.

  • Php Framework Advice

    - by gnomixa
    I am looking for a lightweight php framework with the following qualifications: ability to write my own sql queries ( i simply don't trust CakePHP like method where the framework does your sql for you); ability to integrate Jquery easily; built-in templating, or relatively easy to introduce Smarty (or another templating engine) into it; MVC; fast Any advice/comparison? i have looked into CodeIgniter, Symfony and CakePHP so far. Symfony is slow, and CakePHP is too inaccessible ...so far my choice would be CodeIgniter. I played with it a bit, but i would like to hear more experiences. I am looking for a framework that will "enforce" organization of my app in a logical way - MVC seems like a great choice.

  • ObjectContext.SaveChanges() fails with SQL CE

    - by David Veeneman
    I am creating a model-first Entity Framework 4 app that uses SQL CE as its data store. All is well until I call ObjectContext.SaveChanges() to save changes to the entities in the model. At that point, SaveChanges() throws a System.Data.UpdateException, with an inner exception message that reads as follows: Server-generated keys and server-generated values are not supported by SQL Server Compact. I am completely puzzled by this message. Any idea what is going on and how to fix it? Thanks. Here is the Exception dump: System.Data.UpdateException was unhandled Message=An error occurred while updating the entries. See the inner exception for details.

  • How does one calculate CPU utilization programmatically ?

    - by Scott Davies
    Hi, I have a benchmarking program that calculates the time (in milliseconds and ticks), for a persistance to Entity Framework 4.0. Is there a way to calculate CPU load ? I am guessing that I would need to query Windows to find out my CPU frequency, how many cores, etc. Does this sound right ? If so, what part of the .NET framework relates to querying the system ? I am guessing System.Diagnostics ? Thanks, Scott
