I have a class within a library, with no root namespace, firstone.dll:
namespace first
public partial class one
public sub fun()
[Code]....
Is there a way to extend the class in a separate dll and still have access to the original class? I don't want to inherit the class just extend it.
When you create a webpage in ASP.net, the codebase inherits System.Web.UI.Page Now when I extend the page object to check for SessionExpired for example, I create a new class and inherit from system.web.ui.page, and overwrite some functions. The problem then is that on each page, I have to replace system.web.ui.page with my custompage class. Is there a way to extend a class by adding methods or modifying its methods directly (e.g. add the sessionExpired check to System.Web.UI.Page) ?I'm using .NET 2.0
View 2 RepliesI have a base class which needs to define an enumeration:

- SomeEnum
I then need to create two derived classes from the base class and extend the values in the enumeration:

In C# or VB.NET can someone provide the syntax to do this?
I have to create an XML database for a class I'm taking, but I'm running into some problems. I'm trying to pack my data directly into the DOM using some classes I created and derived from the XMLDocument class, I'm trying to do it this way so I can easily manipulate the entries while the document is in memory and save them back to a file without having to mess around too deeply with the XMLDocument class. I'm running into some problems however when I try to typecast the elements I get from calling
Code:
XMLDocument.DocumentElement.Item
I assume that this is happening due to my derived class not being pushed into the DOM when a file is loaded, because it works just fine if I enter the data manually in code.
Code:
Option Explicit On

I have the same problem as this poster, however I am using a .net gridview and would like render my html to use the fix offered here.Using CSS to create table cells of a specific width with no word wrapping. EDIT I think I may be going about this all wrong, maybe you don't change the rendering by extending the BoundField, but rather add the properties to the boundfield then change the way the gridview renders its fields based on the properties of those fields.Which also leads me down the path of control adapters,

I'm writing custom code in VS2005 Reports (SSRS / Report Builder). The code is working fine, but I have to make absolute references to assembly classes. For instance:For Each m As System.Text.RegularExpressions.Match In ...Is there any way to alias the reference to System.Text.RegularExpressions.Match, so that I can reuse it in a concise manner? I know in PHP, you'd do it like this:
use MyNamespace\MySubNamespace\MyClassVerboseName as MyClass

MyClass->MyMethod();

I'm moving some stuff around in a program. How do I move a class (or enum, etc) to a different namespace? Right now I am getting 102 errors because even though VS can update name changes, I don't see how to get it to update a move to a difference namespace.
EDIT: Okay, to be more precise, I am moving a class up the namespace tree. So, not just a different namespace, but actually getting rid of the last namespace qualifier.
While going thru an msdn article, I found a reference to System.Query.Sequence class. But when I try to use it, I get error "Query is not a member of System"

Select New With {.Number = n, .OddEven = If(n Mod 2 = 1, "odd", "even")}

The above code is vb.net version of this code from msdn. So what is the correct namespace of this class? Or I'm missing something else?
I am attempting to use the My.Computer.FileSystem namespace in a WPF VB.NET usercontrol library. I get no Intellisense etc for this namespace. I imagine I need to add a reference but no amount of googling has fixed this and VS.
View 1 RepliesI've currently got a class that has a bunch of functions within it that I'd like to group up. I can't seem to find a way to do this, as the functions interact with the objects within the class (so I can't use a structure for example). Namespaces are only allowed outside of Classes as are modules. Let's say I have Class Foo. Inside Class Foo there are six functions, three that are logically grouped together and another three that are as well.
Class Foo
Public Function moneyFoo1()
Public Function moneyFoo2()
Public Function moneyFoo3()

this is what i want to do. I have a class library project into my solution. Into it i have a class. I want that class to be instantiated as soon as the solution starts.

Why is VS asking me to call the namespace twice if I use the "Imports" directive?I'm sure this has got something to do with VS2010 and the 4.0 framework.
In the code below, the namespace is called "Navigation" which I think is correct. Then I have a class called "Heading", which by definition is the direction a person/vehicle is truly pointing towards. I think that is also named correctly. In the code below, I have four things I have named:
_WhatToName1, WhatToName2, WhatToName3, and WhatToName4.
The value that gets passed in and stored is a double between 0 and 360 -- essentially the degree value from a circle. For WhatToName3 and WhatToName4, I have seen a lot of places that just use "value" as the name. Is that standard?
Namespace Navigation
Public Class Heading
Private _WhatToName1 As Double
Public Sub New(ByVal WhatToName3 As Double)
Me.WhatToName2 = WhatToName3

I am attempting to move a highly referenced class from one namespace to another. Simply moving the file into the new project which has a different root namespace results in over 1100 errors throughout my solution.Some references to the class involve fully qualified namescape referencing and others involve the importing of the namespace.
I have tried using a refactoring tool (Refactor Pro) to rename the namespace, in the hope all references to the class would change, but this resulted in the aforementioned problem.Anyone have ideas of how to tackle this challenge without needing to drill into every file manually and changing the fully qualified namespace or importing the new one if it doesn't exist already?

what websites, books or courses you guys suggest to use so I learn the fundamentals of programming. What is a class, method, namespace, private vs public. That leads me into .Net programming.

Is that possible to create a class in vb.net that is not in the default namespace of the project?
for example, say you have a project call sample1, then automatially IDE will have everything default to the Sample1 as your namespace root rather than under global, which is find for most case.but I want to create some classes that is directly under global namespace
I have a large web app in vb.net 4.0. Its default namespace is configured in its project properties. None of the root-level classes in our app are surrounded by namespace declarations. When I add a .asmx file to the root folder of the website, it compiles fine, but it doesn't work for some reason (already asked why in other topics). So to get it to work, I try to surround the class declared in the .asmx by a namespace declaration. As soon as I do this, I go from zero compiler errors to about a zillion. My app can't find ANYTHING in the root namespace. But I haven't changed any other files, only this .asmx file.
WHY is it behaving this way? How do I prevent it from behaving this way without refactoring the entire app? I would love to blank out the default namespace and add them explicitly around every root-level class, but I'm not sure that would fly with our release manager, and I don't even know if it would fix the problem.
