Architecture :: Use A C# Class Or A Interface?
Feb 3, 2011I have a block of SQL statements that I like to use as a sort of function.
I was thinking that I could make a class and inherit all of the master function, then add the parts that I need for other sections of the program in a sub class.
The problem is, up to this point I've been programming ASP .Net through visual studio, and it's kind of just programming behind controls. I'm not sure where to put the class/function/method/interface, or whatever we call it.
Of course you probably know that visual studio creates a bunch of partial classes when you do an ASP. Net application... so.. to get access to a function like object, across classes.. use an Interface?
Custom Server Controls :: Implementing An Interface From A Class Library In A Custom Control?
Jul 8, 2010I'm building an n-tier application, with the web client and the class library separate. I'm also using the factory pattern of development, using interfaces to act as containers for different objects they are associated with. The problem I'm expreriencing is that I declared a public interface class in the class library and I can create an instance of it in in my aspx pages but whenever I declare it in my custom control code-side, i get an error, like so:
Error 20 The type or namespace name 'IContentMaker' could not be found (are you missing a using directive or an assembly reference?)
notge that I have inherited the class library namespace using the 'using' keyword just in case you are wondering. My code is like so:
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using TQO_Classes ; //importing the class library project
public partial class PageContentMgr : System.Web.UI.UserControl
{
private IContentMaker _data; //this line throws the error, it works fine on aspx pages

View 3 RepliesHow To Use Web Class Library From A Windows Project
Feb 19, 2011I have a Web project in which I defined some methods to parse some webpages. I then save the retrieved data in a DB. Now I have run a lengthy operation(it may take 2 days) in which I continously parse webpage this way.
Can I use the webproject from a Windows project. If I try to add a refference to it it doesn't work. How should I do it? I have used until now an asp.net application, and done the calls to the parsing methods in the pageLoad event but after an hour or so the process stops.
WCF / ASMX :: Creating Class Library From Web Service?
Dec 17, 2010We are consuming third Web services.
Instead of using datatypes from web service proxy we need to create our own class which will take the values from web service output.
Since the web service data types are so much deep,we are facing lots of problems to create our cutom classes.
Is there any tool available to create classes directly from web services in ordered way....

C# - How To Add A Reference To A Web Application Project In An Associated Class Library
May 13, 2010I'm working on an internet application that has been set up as a web SITE project (I know...) in Visual Studio. I need to add additional features/functionality so have added a class library to the project and referred to it in the main web site project.
The issue now arises because I need to make use of core objects which live inside the App_Code directory in the web site project but this project doesn't appear to expose its DLL like web app/ code library projects do. Because of this I can't add a reference to the web site project in the class library to leverage the common site-wide code/objects.
I can't move the stuff out of App_Code so I'm looking for a way to refer to the website project dll from the new class library.
Asp.net - Moving Functionality To A Class Library Project ?
Mar 30, 2011I have a .net project whose part of the functionality is xls transformation. I now want to move that functionality away from the main project to a separate class library project.
I have no problems moving classes and accessing them, but part of the resources that I wanted to move were xslt files that define the transformations. Those files were originally located in the special asp.net folder: App_Data and then accessed using Server.MapPath(~/App_Data/XSLT/anXsltFile.xslt)
I wanted to move those files to that separate library as well, but not sure how to approach it, and how to access those files within the class library.

VS 2008 Adding Css File To Class Library Project?
Jan 10, 2011I have a custom gridview control which is a class library project.I want to be able to specify the css class for the gridview which I can do.But I also want to set a default css stylesheet to the gridview.

Configuration :: Accessing C# Windows Class Library Project DLL?
Jun 8, 2010I have one C# windows class library type project which has a web reference whose settings are automatically added in to settings.settings file( Webservice name, type, scope, value).
I also have one separate ASP.net project which has let us as suppose, one page with a button. When I click this button, it calls a method of referred DLL of previous project and control goes there.
When in that project, when control goes in to location where I use this web reference, it tries to get the URL of web reference from settings file and raises an exception - 'The current configuration system does not support user-scoped settings'.
So, What is the way for me to call a c# project having web service in a asp.net project ? This is really a source stopper for our development.
How To Make The Setting Works For Class Library Project In C# 2.0
Jan 29, 2010I am putting the setting under the property of one of my C# Class Library project for app setting:
EUCAccountService_ConnectionString
EUCTelcoDB_ConnectionString
In the development, it works nicely. Until I deported to production, I realise that the component that use those thing .. it just hang. I found that under BIN when it compiled dewaCorp.EUC.TelcoDB.Data.dll.config and open up that file and turn out nothing.
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
</configuration>
How to make this works? I thought by compiling it, it turned to some sort config file or something. But it didn't.
How To Access Session Object Outside The Web Project (class Library)
Oct 29, 2010I am implementing a custom membership and role providers where I need to store all the role/membership information in the user's session.
I am implementing these custom providers inside a class library project (different from the website project) and need to access the session in them. The idea is to store the role/membership related information in the session after retrieving them for the first time from the database.
When I try to access the Session using System.Web.HttpContext.Current.Session
I get this as a null object (Object reference not set to an instance of an object.
Why is the session turning out to be null?

Visual Studio :: Code Behind Page Not Recognizing Class Library Project?
Jun 11, 2010I've got an ASP.NET 4 web forms application I'm building in Studio 2010. The solution has two projects. A web forms application and a class library. I have added a reference to the class libraryr project in the web forms project, but when I go a code behind page in the web forms project, it does not recognize the class from the class library and throws the "type or namespace <class> could not be found ...." error. Adding a using <class library projec> does not work either as it does not recognize that.
What am I missing?
Folder / Contents Of Class Library Appearing In Website Project Of Web Application
Oct 8, 2010When I make an asp.net web application and add class libraries to the solution, the website project itself has a folder with the same name/contents as the class library.
Eg I make a web application called Test, add a project which is a class library, to the solution, called testAbc, and then there is a folder at the root of the website project called testAbc with the contents of the class lib.

Architecture :: Interface, Abstract Or Inheritance?
Oct 7, 2010I have a table which houses two entities. StaticProgram and DynamicProgram. There is one column in that table called ProgramType which determines if a program is of Type static or Dynamic. Though these two entities are stored in one table (I am guessing because the primitive fields for Static and Dynamic programs are exactly the same) but from a business point of view these are two VERY different entities.
So, I created two Classes StaticProgram and DynamicProgram. However, I donot want to create two seperate Data Access Classes because it is going to be the exact same code replicated twice. I tried creating a "Program" class as base class and inherited StaticProgram and DynamicProgram classes but down casting is not supported so I can't return a "Program" object from the data access class and cast it to "StaticProgram" class.So, what are my options? Can I create an IProgram interface and have StaticProgram and DynamicProgram implement that interface and have my Data Access class return IProgram?
