I have a base class that has a specific parameterized ctor. I use it as the base for several concretes. These concretes have zero need to alter ctor behaviour, and thusly, I see no reason to define one. However, as you may guess, I get the "class has no ctor that takes 0 arguments" error on compile. Is there a keyword I can place on the base class ctor that will prevent the error? Or maybe another way around it? This is indenpendant on any ioc usage by the way. It's merely a set of objects that MUST take an argument, and it so happens, the base class handles everything that it needs. The derivations simply no reason to re-declare the ctor, just to pass it on to base();

Have an asp.net app with a local rdlc report based off an xsd dataset. Was working fine, but i needed to add another field, so I added it to the dataset through the designer (right click, add column) and then added the field to the rdlc report.
My problem is it won't compile - keep getting the error:
The Value expression for the textbox 'Description' refers to the field 'ShortDesc'. Report item expressions can only refer to fields within the current data set scope or, if inside an aggregate, the specified data set scope.
I've cleared the cache, deleted temporary internet files without luck.
So how do i get the new field to show up for the report?

View 3 RepliesI am confused about the constructor of ObjectContext
// Summary:
// Initializes a new instance of the System.Data.Objects.ObjectContext class
// with a given connection string and entity container name.
//
// Parameters:
// connectionString:
// The connection string, which also provides access to the metadata information.
//
// defaultContainerName:
// The name of the default entity container. When the defaultContainerName is
// set through this method, the property becomes read-only.
protected ObjectContext(string connectionString, string defaultContainerName);
I am not understanding the parameters clearly.
if a class has a private constructor then it cant be instantiated. so, if i dont want my class to be instantiated and still use it, then i can make it static. what is the use of a private constructor? Also its used in singleton class, except that, is there any othe use ? (Note : The reason i am excuding the singleton case above is because I dont understand why do we need a singleton at all ? when there is a static class availble.
View 8 RepliesI have a connection string defined in my web.config like:
<connectionStrings>
<add name="LibraryConnectionString" connectionString="Server=.SQLEXPRESS3;Database=Library;Integrated Security=true" />
Well...lI do not understand why when i drag-and-drop tables into a new DataClasses dbml it does not construct a default constructor specifying the connection string. I only have constructor with params like:
public DataClassesDataContext(string connection) :
base(connection, mappingSource)
{
OnCreated();
}
I do need a default constructor for LinqDataSource..
I have the following constrcutors within a Model and I want to click the create button on a previous view and pass the projectID in and call the second Constructor so I have the projectID on this view. Do I need to change the routing in someway to call the constructor with the parameter? -

I'm using Microsoft Unity. I have an interface ICustomerService and its implementation CustomerService. I can register them for the Unity container using the following code:
container.RegisterType<ICustomerService, CustomerService>(new TransientLifetimeManager());
If CustomerService has a certain parameter in its constructor (e.g. ISomeService1), I use the following code (I need to specify SomeService1):
container.RegisterType<ICustomerService, CustomerService>(new TransientLifetimeManager(), new InjectionConstructor(new SomeService1()));
No problems here. The problem appears when CustomerService class has two parameters (not one param as in the previous example) in its constructor (e.g. ISomeService1 and ISomeService2). It works fine when I'm using the following code: container.RegisterType(new TransientLifetimeManager(), new InjectionConstructor(new SomeService1(), new SomeService2()));The problem is that I do not want specify SomeService2() for the second parameter. I want to specify only first parameter - SomeService1(). But I get the error that I need to specify none or both of parameters. How can I specify only first parameter of constructor?
I've created a web service , which can a method to set the user credential using Microsoft.Web.Services3.WebServicesClientProtocol. The sample code is :

Public Sub ClientCredential1(Of TSecurityToken As SecurityToken)_

When I run the web service it gives this error: "Microsoft.Web.Services3.Security.Tokens.UsernameToken cannot be serialized because it does not have a parameterless constructor."
I have a Class called Repository for accessing (Read/Write to and from) Database.The projects that require access to the database create an object of Repository and pass the connection string as a constructor parameter for the repository to work for that particular project.
I have few methods in the Repository that i want to be available only if certain connection strings are passed. I don't want them to be available if some different connection string is passed.Is there any way I can accomplish that?I have never used method header technique, if yes, how can i use it? if no, please let me know if there is any other way to achieve my goal.
I'm very new to Visual Studio and I am getting this error when trying to update an Oracle table from Gridview using a tableadapter datasource. I've followed the instructions in my text very closely but am at a loss as to why this error is occurring.

this is the stack trace error I am getting. At this point, I'm a little clueless how to resolve it.
I am doing Music Store sample application.Here my code.

StoreController

Create.aspx
[Code]....
But when i click Save it show Error

when we declared as static then we will not create the object to call the static method. then my doubt is how is call the static constructor after creating the object?can you explain cleary?
View 1 RepliesWhat's the best way to handle exceptions that happen from within a controller's constructor?
All I can think of to do is use Application_OnError() or put a try/catch in my ControllerFactory.
Neither of these solutions seem ideal. Application_OnError is to broad - I have some non-mvc content in the site that has its own error handling. Using a try/catch block seems kinda hacky.
If I'm serving different content type -html/text/json/rss.... I would like to be able to handle the exception from within the action method instead of having to write all kinds of conditions to determine what kind of error message to serve.
I just struck upon a prime opportunity to further exhibit my MVC ignorance, by way of the following: How can one make use of a custom view model class that has parameters in the constructor? For example, a class that could intitialize various collections/properties based on an IPrincipal object passed in. I've come across several allusions to this scenario, involving a class inheriting DefaultModelBinder which overrides the CreateModel method, but have yet to find an example.

In my project I work with Entity Framework (LINQ to ENTITY). I only have ADO.NET Entity Data Model and a DAL (Data Access Layer). I also get the data due a WCFClientService. I have a gridview that needed to be exported in Excel.

Is there a way to convert the data in my gridview to a virtual DataSet?
