Namespaces

Hi

I am trying to understand how namespaces work in VB.NET. The program works
partly, i.e. the first two writeline statements work. With the other ones I
get problems, VB doesn't seem to accept my Imports statements. Can someone
tell me what I am doing wrong is this program?

Imports System

Imports GeefMe = One.Eleven.Gimm e ' alias voor class

Imports EenEenEen = One.Eleven ' alias voor namespace

Imports One.Twelve

Namespace One

Namespace Eleven

Public Class Gimme

Public Function GimmeAnA() As String

Return "A"

End Function

End Class

End Namespace

Namespace Twelve

Public Class Gimme

Public Function GimmeA1() As Integer

Return 1

End Function

End Class

End Namespace

End Namespace

Class app

'Module Module1

Shared Sub Main()

Dim a As One.Eleven.Gimm e = New One.Eleven.Gimm e

Console.WriteLi ne(a.GimmeAnA)

Dim n As One.Twelve.Gimm e = New One.Twelve.Gimm e

Console.WriteLi ne(n.GimmeA1)

Dim b As GeefMe = New GeefMe

Console.WriteLi ne(b.GimmeAnA)

Dim c As EenEenEen.Gimme = New EenEenEen.gimme

Console.WriteLi ne(c.GimmeAnA)

Dim d As Gimme = New Gimme

Console.WriteLi ne(d.GimmeA1)

End Sub

'End Module

End Class

Before you can use Import to import a namespace, you must have a reference
to the assembly that contains that namespace. Do you?

That's what I finally did and it worked fine. But when I wrote the same code
in C# I didn't had to do that, that's why I was puzzled.

In the "empty classes as c structs?" thread, we've been talking in some detail about my proposed "generic objects" PEP. Based on a number of suggestions, I'm thinking more and more that instead of a single collections type, I should be proposing a new "namespaces" module instead. Some of my reasons: (1) Namespace is feeling less and less like a collection to me. Even though it's still intended as a data-only structure, the use cases...

What see sample that show xs:element where the xs namespace = http://www.w3.org/2001/XMLSchema However, I see another example with xsi: where xsi = http://www.w3.org/2001/XMLSchema-instance What's the difference here? Are there right and wrong namespaces? Is there a global list of the ones to use? Does the namespace even need to point at http://www.w3.org.....? Or is this just the accepted way?

Trying to get the hang of Namespaces. I have primarly developed in VB and am transitioning to C# and the .Net Environment. I have worked a bit with Java as well in school about a year or so ago. NameSpaces and Java Packages are similar in nature? In the dot net world, you are not able to pick out (import) a particulare "class" within the namespace - just the entire namespace. Is that Right? In Java, I would carve out a place on my...

Using 2.0 with Master Pages and a GlobalBaseClass for the content pages. I understand the easy part -- the hierarchical structure of a namespace naming convention -- but the 2.0 IDE does not write a signature for the developer and after getting a good start developing a 2.0 application I thought I should go through the code and start marking classes and with namespaces. I keep getting the following 'missing' error even when using a first...

I'm confused about the proper use and usefulness of namespaces. I beleive I understand the purpose is so the developer can put classes within namespaces to essentially organize your code. And I understand that you declare your intention to use a namespace within a page through the "Inherits" attribute. I know that using "Inherits" isn't absolutely necessary, it's just recommended so the developer doesn't have to type out the entire...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...
