I'm using VB in ASP.NET, i would like to abort a class.
Best would be during the new member.
The result should be: Nothing
Is this possible?

What do you mean with 'aborting' a class?
If you mean setting an instance of a class to Nothing in the constructor of
that class... AFAIK that can't be done.

No. I'm almost positive new is always guaranteed to return an instance, or
throw an exception, no alternatives.

Oh, and by the way, it's a good thing that it can't be done, else you'd have
to check for null each time you used new...ugh..ugly code.
The solution, by the way, is to your a Factory. make the constructor
private, and then create a static (shared in vb.net) method:
public class product
private sub new
end sub
public shared function CreateInstance() as Product
if (whatever) then
return nothing
end if
return new Product()
end function
end class

Maybe you are right.
Similar:
A com interface should be possible to be recreated if it could be created
the first time.
(A short of guarantee/guideline which should be followed)
I guess it's no different for these kind of objects qua strategy.

Sorry, Edwin. It was an abortion joke. Tasteless, and probably meaningless
in Holland. Pay no attention to the man behind the curtain.
