[AccessD] OT: Modify the default event handlers to mimicthebehavior of VB 6 control arrays (VB .NET)

Exactly, that's what the Handles keyword is all about.  Delegation is
one of the new VB.NET features that opens up all sorts of possibilities.

Notice the argument list for the button click handler:
ByVal sender As System.Object, ByVal e As System.EventArgs

These standard arguments are used for all handlers.  Therefore, you
could create a single handler to handle your button click and a checkbox
click (and a textbox change for that matter!).

The Handles keyword serves as a nice tidy wrapper around the
System.Delegate assembly.  There are some cool things that can be done
through code, like dynamically assigning a method from one class (or
control) to be automatically handled by another classes method.

Hi Brett and John

Brett, thanks for clearing this up. I can see I have been victimised by
unreadable code as I - as you guessed - wearing my Access goggles read
Button1_Click as the event handler.

So this in the "reverse" of calling a sub from several events?
You specify a sub and specify - withing this - which events should call
the sub? Have in mind please, that I'm not familiar with neither
VB6 or dot Net.

Of course you are both right about WithEvents. However, sometimes you
just need to, say, have updating of a checkbox and clicking a button to
do the same; then I don't write duplicate code but move it to a sub
which I call from the relevant events.
