Passing an address as an argument

[Just Me]

I have these three statements:

gFormCheckForCancel = New FormCheckForCancel

AddHandler gFormCheckForCancel.Cancelled, AddressOf UserCancelled

gFormCheckForCancel.ShowForm()



I'd like to move

AddHandler gFormCheckForCancel.Cancelled, AddressOf UserCancelled

to ShowForm()

and pass

AddressOf UserCancelled

as an argument of ShowForm()



But I don't know how.

Can someone tell me?

Hi,

Take a look at delegates

I know a little about them. I've even used MouseEventHandler in a similar
situation.
But do not know what to use here.


Thanks

I think I found how to do it. Seems
Public Event Cancelled(ByVal sender As Object, ByVal e As EventArgs)

creates a type CancelledEventHandler.



I still do not understand some things.

I believe Cancelled, as defined above, is a delegate, but

is it a class or a type.



Help sometimes seems to use delegate as a class and sometimes as a type.

I don't understand when a delegate is a class and when it is a type.



Thanks

Hi,

Declare a delegate sub and pass a variable of the delegate sub name.


public delegate sub MySub(byval Arg1 as integer)

dim MyAddressOf as new mysub(addressof theSub)
