Extends in C# or VB.NET?

[tascien]

In java, you can do:

public class MyJButton extends JButton{
public MyJButton(){
}
}

then you can use this custom button as if it was a JButton...

Applet.add(new MyJButton());
same as
Applet.add(new JButton());

is it possible in C# or VB.net?

Question 2:

In vb.net i can do:

Dim ohttp As Object = Server.CreateObject("MSXML2.ServerXMLHTTP")
ohttp.Open ("GET","http://www.google.ca",false)
ohttp.Send()

But in C#, it says that Generic Object does not have 'Open' method?
what can i use?

In C#:
public class MyJButton: JButton
In VB:
Public Class MyJButton
Inherits JButton

In answer to question 2:

C# doesn't accept (I think it's called) late binding. So the object you
declare must expose the methods you want. I'm not familiar with
ServerXMLHTTP, but you'd have to do something like:

Object ohttp = Server.CreateObject("MSXML2.ServerXMLHTTP");
ServerXMLHTTP http = (ServerXMLHTTP)ohttp; // explicit cast
http.Send();
....

which has this specific example under the heading "OnStartPage and OnEndPage
Methods", about half way down the page. (Note: that this link will only work
if you have the documentation on your machine. Maybe someone has the actual
URL at microsoft?)
