Creating And Using Namespace?
May 25, 2010
I've googled for creation of namespaces and found some very useful examples, what these examples didn't have is how do I compile and implement my created namespace on my system so I can include it from my various applications.So for example, if I create a namespace to load a config file from my application path and insert it to an array, Do i need to include the namespace on any project I use or is there a way to make it part of my environment?

We are migrating our applications to VB.Net 2008 from Classic VB and I need to create a base namespace and business layer. My method of approach is going to be to visit our top BA and identify the common areas of our (Fixed Income) company and try to form a decent inheritence model with as much of the code in generics as possible. What's everyone's experience of doing this and also as a second part of the question, we are looking at incorporating Web Focus into the OLAP side, how would this affect the design of the corporate namespace and it's derivatives?

I need to read an xml document from a database record into an XDocument object in order for it to be deserialized. So that the deserialization will work, I need to apply a specific namespace to each of the level 1 elements. So XML looks a bit like this:

How do I prevent the blank/empty namespace being added to each child element of the element to which the required namespace has been applied?

This class is located in the namespace Acme.Infrastructure.Interface.A class with the same name EventArgs exists in the System namespace.In another project in my solution I have a class Acme.BusinessModules.MyModule.MyClass.When attempting to use the EventArgs class I have to fully qualify the class name or the compiler thinks I am using the System.EventArgs class.My understanding of namespace resolution was that the compiler would first look for the class in the current namespace, and then its parents. It seems that the compiler checks in System before it checks in sibling namespaces. Is it correct that System is checked before the sibling? Or is this behaviour caused by other issues (Imports order?)?

I've been developing a Vb.Net app lately, and I'm trying to make it as lightweight as possible (ie make the binaries as small as possible).I've done all the trivial stuff, but while browsing the binary with ILDasm, I noticed that it has a My namespace, with a lot of methods, although I don't use any of these in my program. It seems that there are default Get/Set methods for every form, and other methods.Or, can you show me a use case for the methods bundled by default in the binary? PS: I guess it's not going to make a huge difference in binary size: I'm just asking this out of curiosity; why would the compiler bundle useless methods in every binaries? Perhaps I'll learn that these methods are actually used somewhere under the hood.
PPS: Here's a minimal example:
Module Test
Sub Main()
End Sub
End Module

Using VB.net, I have a namespace which I'd like to rename for the future. However, I'd also like to keep the old obsolete namespace for a time to ensure backward-compatibility for our consumers for awhile. Is there a way in .NET to have two namespaces, one ordinary and one that merely is an alternative name for the other?

I'm trying to add the Compatibility.VB6 namespace in some of my VB.NET Programs (using 1.1 framework, 2003). It was added in one of my programs because of a migration wizard but i can only use these commands in that particular program. How would I add that to the others?

I am trying to work out an example from ".NET Domain Driven Design with C#", which contains a code example where you can see declared some attributes of type DelegateCommand. Now, I've tried googling it up, but I can't find its reference anywhere on MSDN (actually, I found this article, but not DelegateCommand's article itself). Is the DelegateCommand something that's part of WPF or is it just something created in the book?

I'm currently maintaining some old code for a company. As it would happen, the current app I'm modifying uses an older version of the in-house library (we'll call this Lib1.dll). They also have a new version of the library called Lib2.dll that improves upon the previous library in many ways.
Unfortunately, Lib2 is not backward compatible with Lib1. What's worse is that they both use the same namespace Product.Common.
How do I use Lib2 and Lib1 in the same project? Right now if I add references to both of them, VS tells me that certain classes are ambiguous (which makes sense, since they using the same namespace).
Basically, I need something like:
Imports Lib1:Product.Common.Class
I'm using VB.NET 1.1.

What should go into the top level namespace? For example, if I have MyAPI.WebLogic,MyAPI.Compression, etc. If I put classes into the top level namespace, am I violating the principle of encapsulation?

I'm working on a WCF service in VB. I was asked my DTOs are in différentas namespaces. Here's an example with two classes:
[Code]....
But when I come to do a test project to test my service, no namespace does not appear, and put my two classes are the same. The Intellisence going to my first class with the name Reply, and the second class with the name Reply1, while I wanted the same hierarchy with my classes. So I wonder if it is possible to do? I look forward to your responses.

I'm trying to set up a .NET 3.5 web service project in Visual Studio.

I have modified the MSDN example to reflect my problem. When using a namespace I can't get the document to validate as I would expect and when validating a document that doesnt have a namespace it validates regardless of whether or not it has an error in it or not.
Dim errors As Boolean = False
Private Sub XSDErrors(ByVal o As Object, ByVal e As ValidationEventArgs)
Console.WriteLine("{0}", e.Message)
errors = True
End Sub

I've added a new class1.vb file to my vb.net project containing:
Namespace MyFunc1
Public Class MyFunc2
Public Function Add(ByVal n1 As Int16, ByVal n2 As Int16) As Int16
return n1 + n2 ' Edited from: "Add = n1 + n2" (same thing)
[code]....
In form1.vb I thought I used to be able to call my functions with:
n = MyFunc1.Add(15, 16)
The error says "it's not a member".These also don't work as expected:
n = MyFunc2.Add(15, 16)
n = MyFunc1.MyFunc2.Add(15, 16)
n = Add(15, 16)
I thought for sure, this used to work:
n = MyFunc1.Add(15, 16)

I have a public class element from another namespace, called A, that I want to access and use in another namespace, called B. Namespace A and B are in different directories but are a part of the same project and solution. I try using the imports statement and referencing the class itself directly but it doesn't find it. Does anyone know what's wrong?
