Problem extending Object


I'm trying to add an extension to Object using VB. It shows up in the
intellisense for other kinds of reference objects, but not if the variable
is simply declared as Object.

It works without problems when I use C#, but not from within VB...any ideas
as to what is going on?

Imports System.Runtime. CompilerService s

Module StringUtils

<System.Runtime .CompilerServic es.Extension()_
Public Function eMyE(ByVal o As System.Object, _
ByVal sep As Char) As String
Return "1"
End Function
<System.Runtime .CompilerServic es.Extension()_
Public Function eMyE(ByVal o As System.Object) As String
Return o.eMyE(" ")
End Function
End Module
Public Class Form1

Private Sub Button1_Click(B yVal sender As System.Object, _
ByVal e As _
System.EventArg s) Handles Button1.Click
Dim b As String ' sender.eMyE doesn't show up in intellisense
End Sub
End Class
## and here it is in C#

using System;
using System.Runtime. CompilerService s;
using System.Windows. Forms;

namespace TestExtensionsC
public static class StringUtils
public static string eMyE(this object str, char sep)
return "1";

public static string eMyE(this object str)
{ return str.eMyE(' '); }

public partial class Form1 : Form

public Form1()
InitializeCompo nent();

private void button1_Click(o bject sender, EventArgs e)
string b = sender.eMyE();

I accidentally sent this to webmaster@python.org, so this could be a duplicate if "webmaster" forwards it to this list. :{ Hi, there. Thanks for any help that can be offered. I've been working with Python for a year or more now, but only doing simple extending in C/C++. I'm now attempting some embedding and several questions have come to mind.

I'm looking at the O'Reilly Programming C# book and I have a question about extending and combining interfaces syntax. It just looks a bit odd to me, the two syntaxes look identical, but how does C# know which is extending and which is combining? interface IStorable{ void Read(); void Write(object o); }

Hello all, i was just curious if anyone whos been playing with VS2005 could tell me... In javascript (and java??) you can alter the prototypes for an object in your project. I dont remember the syntax exactly, but basically you do something like: function String.prototype.mySplit(myArgs){...do something...}
