I didn't say compiler should stop, interpreter should stop! It shouldn't be legal for same reason as these: Dim a As Integer = "string" Dim a As Integer = Null
It's type mismatch. Null is not same as zero. If you want to be able to give two different object references to same variable, use type object or variant. Also this is change in behaviour, since earlier you had to declare variable for multiple different objects as object. Dim a As Object Only then variable 'a' was able to be whatever; Class1, TextBox or Null. Sometimes I use object as parameter type so that I can use null to signify missing object, but then my code is made to handle nulls. So the biggest problem is debugging. Is there some standard for how this should be? Jussi On Fri, Aug 26, 2011 at 09:20, Caveat <gam...@caveat.demon.co.uk> wrote: > Why shouldn't it be legal?
