Like remove all handler on the myButton.Click.
If you are defining the event yourself:
Let's assume that you defined the 'Foo' event. Then VB.NET will
generate a delegate variable called 'FooEvent' automatically. This
variable provides a 'GetInvocationL ist' method that can be used to get
all the handlers connected to the event. You can use the delegate's
'Remove' method to remove one delegate connected to the event after the
other.

No he's asking for a list of Handler associated with the instance of a class
so he do something like.
ForEach handler in object.MyHandle rs
removeHandler . . . . . . .

Sure, that's what my answer is about.

My answer shows how to determine the handlers added to an event.

I'm not sure I'm putting together your two posts correctly. What's
object.MyHandle rs in the above, I've never seen anything like that
before?
To the original poster, the short answer is that in the general case you
can't do this. You can't clear somebody else's invocation list (in this
case, the Button's invocation list). However, usually buttons only have
handlers on the current form and it's not too difficult to keep track of
those, so maybe that's enough for you.

I assume it's pseudo-code. Nevertheless, there is no such property.

Hi,
Anyone know how to remove a event handler that inherited from another form?
I have a base form, and there is a button with click event in the base form.
1 of my another form inherits this base form, and so the button is shown
with the click event, I want to remove that event without altering the base
form, is this possible?
