Hi EveryBody:

I have some question that I hope some body help me to answer it :

Q1\ How can I Inherits two class inside one class ?

Q2\ How can I convert the fowwloing code from C# to VB.Net :

public event EventHandler ReadyStateComplete {
            add {
                Events.AddHandler(_readyStateCompleteEvent, value);
            }
            remove {
                Events.RemoveHandler(_readyStateCompleteEvent, value);
            }
        }

Q3\ What is equvelant to operater <> and operater "and" ?

Any help or redirection will be appreciated

1. You can't, you can only implement interfaces
2. Sry, not sure on that one...
3. You can use "<>" in VB. or you can use "Not" and =
if Not A = B then
3b. There is no equvilant ? in VB. you can look at iif(..) statements,
they are the closest.

You cannot. .NET does not support multiple inheritance on classes.

Check out 'Custom Event' in VB 2005. You can even add your own
implementation for 'RaiseEvent' there which is not supported in C#.

Both are actual VB operators.
