i want to use namespace and class so that when i want to change the name of my database, or user Id or password, i will only change in the namespace page, so that life will be much easy.here is a namespace creating for vb.net 2005

In VB.net we are creating different namespace level classes. For Example, DynamicPDF - Root NameSpace Test ,Report are two sub folders in side the sub folders some classes.

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 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?

View 2 RepliesThis 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 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()

I VB 2005 you can set the root namespace name of a project under the project properties. Where can I set this using VB2008?

Researching the error tells me that HTMLDocument isn't fully qualified. Isn't this fully qualified? If I change it to Microsoft.mshtml.HTMLDocument then it says it's not defined.

View 2 RepliesWhen you develop a class library that will be used by others, are there any guidelines on how you decide what namespace to put it under? I often find third party classes just use the company name as the root namespace but I was also wondering if it is frowned upon (or even possible) to add one of your own classes to an existing framework namespace.

Which is the best way to store global variables, in My.Settings or My.Namespace. The reason I ask is because I need to know certain boolean values if certain forms are open from other forms. At present I am defining Global Boolean variables in My.Application, which give the result I require.
View 3 Replies[URL] The jist of the problem is in fact that in the weka.classifiers.trees namespace you have the following members:

Lamentably VB .NET in VS 2008 does not seem to be smart enough to distinguish betweem the two (which is odd, because there is no such problem in VS 2003, or in C# in VS 2008) because of it's lack of case sensitivity. Or possibly because of the fact that ikvmc emits an assembly compiled for the 1.1 run time... I'm not sure. I'm also not quite sure how you would resolve this particular issue and given the time sensitivity of this project I do not have the time to learn C# or Java to an extensive degree.
As I say, I've got an application which I'll refer to as "AppName" (note the upper case 'A' and 'N') which, for example, attempts to reference "My.Application.Info.ProductName". Adding a breakpoint and putting a QuickWatch on that call shows the error:

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?
[Code]...
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?
View 4 RepliesI 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?

why use of namespace and use keyword and declaration of namespace
View 1 RepliesI'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?
View 5 RepliesI'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?

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.
