Add a subroute to multiple forms

[Surveillance]

I'm trying to find a way to add a subroutine to multiple forms in VB.net 2k5.

I'm instancing some forms as a property of a class and I need an event that triggers to handle their .dispose property.

I think that's the proper way to describe it. I'm a bit of a noob. Just in case that's not understandable, I'll break it down a bit more below.

I have a public class which contains "Public Myform as Object".
There is are a number of inherited classes which contain "Myform = new (appropriate form)".
When the instance of the form is disposed, I'd like to trigger an additional event.

I can go into each form and add the event, but to keep modification simple, I was hoping there was a way I could create a "handles Myform.dispose" from within the main public class, since it will be the same for all of the various forms that will be loaded.

Initially, I tried using "Public Myform as Form" but because the inherited classes have overloaded events which call properties of their specific form this doesn't seem to work.

Any suggestions?

What I've done is to add a public sub in a module and added a call statement to the .disposed handler of each of the forms in question.

It works well for consolidating the code into one place for updates, but I'm still looking for a way to add this code dynamically to the form from within the class if anyone has any thoughts.
