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.

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);
}
}

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

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

Both are actual VB operators.
