1. The (Overrides) appears so you can select an overridable method in the
right hand drop down and it will
 create the shell of the method you want to override.

For example, if I wanted to override the text property of my form I would
select overrides in the left hand drop down, then Text in the right hand
drop down, this would produce the following code...

Public Overrides Property Text() As String
        Get

        End Get
        Set(ByVal Value As String)

        End Set
    End Property

This method will now override the default(base) Text property of the form.

2. Base class events are different from overrides as they are the base
events of whatever object you are working with.  The overrides are the
methods etc.. Of the class that can be overridden.

It sounds to me like you should pick up a book on .NET programming so you
can learn the fundamental and powerful features of the framework.

1. Windows Form Event Handler

----------------------------------------------------------------------

Subject: Windows Form Event Handler

I have two questions and hope someone could help.
1. When creating a windows form event handler, I have to go to the Class 
Name Dropdown box to choose "Base Class Events" or "Overrides" then 
select the event from the Method Name dropdown box. But other controls' 
events, e.g., command button, are directly accessible without dealing 
with the base class. Why is the difference?
2. Between "Base Class Events" and "Overrides", what's the key difference 
other than the syntax? Which way is better and why?

Many thanks.
