View 4 RepliesUsing A Response Object Within A Class Library
Dec 29, 2010My problem today is that I am having trouble shifting some functionality, that is being used in multiple applications, from the applications themselves to a class library I have started building. The issue comes in the fact the code was written to utilize Response objects as seen below...
[Code]....
This is all currently within a function called "DownloadDocument". I continue to have issues running any of the Response object functionality. I usually get the error saying, "Response is not available in this context", is there anyway to use a Response object in a class library file?

Why Use Reference Of Abstract Class To Create Object
Jul 22, 2010Why do we use the reference of abstract class (or base class) to create object of it's sub-class. eg: TextWriter is the abstract class for StreamWriter & StreamWriter.
TextWriter writer = new StreamWriter();
why can't we simply use :
StreamWriter writer = new StreamWriter();

What Happens With Unused Properties Of A Class When An Object Is Instantiated
Aug 5, 2010I am interested to know what happens with unused properties of a class when an object is instantiated?

C# - Sharing An Object Between Methods In Same Class (with Postback)?
Nov 19, 2010I have a user control with a number of methods. I also have a dataset object that I'm filling in one method, but I also need to access that same dataset (and the data in it) in another.
I am filling the dataset from some xml that I get from a webservice when someone clicks on a button. The data from the dataset is then bound to a listbox control. When someone selects an item in the list control (I have autopostback set to true on it) it then fires off another method and it's this method where I need to access the data in the dataset, but when I check the immediate window it's telling me that the dataset is set to null.
Where am I going wrong?

SQL Reporting :: Is It Possible To Use An Object (class) As A Datasource For A Rdlc
Mar 2, 2011When I create a report in my Visual Studio 2010 (SP1 Beta) Web Site and select New->DataSet ... from the Report Data window, the DataSource Configuration Wizard goes directly to 'Choose You Data Connection'.
In the desktop world the wizard first presents the 'Choose Your Data Source Type' wizard screen where I can select 'Object' as the type. In my case it skips this screen and goes directly to the 'Choose You Data Connection' wizard screen as if I had clicked 'DataBase' as my type. Note that I do have 'LINQ to SQL Classes' in my project.
I have reviewed the following link but it does not seem to in my case and I am using dbml rather than xsd:

C# - Access To An Object Created In Page From A Class?
Jan 18, 2010I have a page, Default.aspx, with its own code-behind file like this:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class _Default : System.Web.UI.Page
{
public int[] anArray;
}
What I'd like to do is access to "anArray" from a C# class (not tied to a page) declared in App_Code folder. What can I do?
Edit: As said in the first comment, I really apreciate your about refactoring my connection objects. However, what I'm really doing here is to rewrite an old PHP application in order to get comfortable with basic C# and ASP.NET, so this code will never go really live. So, I'm still intersted in a way (if any) to access an object declared in a code-behind code from a standard C# class.
Edit2: I removed the OdbcConnection object in order to focus to the real problem: how to refer to an object istantiated in a code-behind file from a C# class situated in App_Code?
ADO.NET :: Update Value Directly In Class Object Using Linq?
Sep 30, 2010I have a class object which is basically kind of hierarchy and looks like this when I convert that to XML.
[Code]....
So you can see that I have "objectComponent" which is kind of hierarchy and that hierarchy can be upto any level.
Now I need to update <quantity> value where <sku> = "SKU 2", remember this <sku> can be anywhere in hierarchy, so I need to update its <quantity> value where <sku> = "SKU 2".
So my question is how can I update that value using Linq query and specifically, I need that value to be updated in the actual object itself because I need to pass that updated object for furthur process.
In my c# code, there is only one class named "ObjectComponent" and that has all of these properties and "objectBundle" as array and the whole hierarchy starts from there.
how can I update value in this object directly?

C# - Get The Name Of The Class Without Instantiating Object Or Having A Static Method?
Feb 22, 2011I hate to see the name of the class used as a string parameter like "FileDownloader" in the code, and I would like to use something like this FileDownloader.Name(), where FileDownloader is name of the class.
Only problem is that I can't find out how to do that without instantiating object or creating a static method...
Is there a way to get a class name in .net without having the object instance and without creating a static method that returns the name of the class?
State Management :: Persisting A Class Object?
Nov 5, 2010I wish to persist a class object across postbacks by using a single session variable/object/whatever.
The class has about a dozen single variable properties; and about a dozen table properties; and several methods. The main table tracks rows of sporting event results. The web site will collect one row at a time for each postback. The data in the object's constructor is based on a dataset, but the data in the class will grow each time I do a postback so I don't want to loose the information in the class. The data isn't very big - it will fill a single computer screen.
Being new to programming I am thinking that I can store the dataset in the session but that would slow down the response time because I the methods would have to be called to refine the data - or maybe I can just store the entire class object in a session.
