calling class instances and their methods

hi,

i created an instance of a my own class which has methods and all. now
i get an outside function called, which is unfortunatly not aware of
the instace at all (i don't control how this outside function is
called). but i would like to get access back to my instance and it's
methods.

is there any clean way of doing this ?

thanks in advance

I don't understand well. Do you want to call a method on your object,
from inside that external function? Can you modify its code?

Ummm... I'm not exactly sure what you mean by "an outside function", but
let's refer to that function as f(). Are you saying you want to re-implement
f() to use your new object but don't want to (or can't) change calls to f()?

If so, then you can either use a global reference to your new object if
it is the sort of thing you want to keep around between invocations of f()
(i.e., create your object somewhere and then save in a scope that f() can
access). Otherwise, you can simply instantiate your object inside of f() as
a local variable and use it.

If you mean something else, I guess you will have to clarify.

Hi, I don't get the difference between a struct and a class ! ok, I know that a struct is a value type, the other a reference type, I understand the technical differences between both, but conceptually speaking : when do I define something as 'struct' and when as 'class' ? for example : if I want to represent a 'Time' thing, containing : - data members : hours, mins, secs

Hi, I am a VB.net beginner, I do not know what are the major difference between Module vs Class. Could someone guide me when is the best situation to use Module or Class. I have no idea when should I use module or class, because no matter i use module or class, i always could get the results that are what i want. but just the declare and calling method is a bit different.
