Dear all,
I read many documents and article based on Interface, but
I am still blind with that and start to have no more hairs.
I try to clearly understand when should I create
Interface ?
thanks to clear my stupid mind

In a recent thread, RKC (correctly, I believe), took issue with my use of
multiple parameters in a Property Let procedure to pass dimensional
arguments on the basis that, although it works, it's not obvious how the
code works if you don't know the intricacies of the Property Let/Get
syntax. Likewise, I dislike (and code to minimize the use of) the VB/VBA
syntax of returning a value by referring to the function name as if it were

Hi
Straight to the point - I don't understand why System.Array derives
from IList (given the methods/properties actually on IList).
When designing an interface you specify a contract. Deriving from an
interface and only implementing some of it means something is wrong:
either the interface specification is wrong e.g. not minimal or the
derivation is wrong e.g. the type can't actually honour this contract.

Hi.. I was looking at interface, and I have a example in the docs i'll
paste below.. I'm not grasping what you would gain by using a
interface, does any one have a brief description of their benefit?
Thanks,

I have a question pertaining to the implementation of an interface's
contract, specifically why in some interfaces the InterfaceName.method is
required when other times just the Interfaces method name will work. For
example,
When using ICollection.CopyTo Method I can implement the CopyTo method as
follows (notice the interface name is omitted):
public void CopyTo(Array array, int index)
{

I am puzzled, what is the purpose of an interface? How does it work,
what i mean is how does the compiler treats this? Why when we talk
about separating user interface from business logic, an interface is
declared, what is it's purpose?
thanks,
BRAMOIN

I've got a good question about object-oriented programming, I hope I can explain it well enough. I'm creating a UserManager, which I'm going to inherit from so different applications can share common methods.
Public MustInherit Class UserManager
Public MustOverride Sub AddUser(usr as InternetUser)
End Class
Public Class InternetUser
Public username as string
End Class

I have a static event declared in a C++ ref class, that can then be handled
in a VB app. I'm trying to expose the static event through the interface
that the C++ ref class implements so the VB app can use the interface as
preferred. How do you expose a static event through an interface?
In the example below as coded, in a VB app I can access and use the general
method (MyMethod) if I declare my handle variable as an IMyInterface type....

These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
