Easy one: (?) how to kill instance of form class?

[Jim]

I was wondering if there is a way to completely get rid of a form instance, no matter who has references to it.

Suppose that I have a datatable on form frmList.
I show frmDetail from a button of form list:
dim f as new frmDetail
f.Show

Now suppose frmDetail adds a handler to a datatable that lives on frmList:
AddHandler dtList.ColumnChanged, AddressOf ccHdlr

Even If I put me.Dispose in frmDetail's closed event, changes to the datatable call the handler for the previous insantce of frmDetail. I thought my form was gone when I closed it, but it lives on through the handler.

I know I can remove the handler in frmClosed. I was just wondering how to really trash the form, even if some other objects have references to it.

You cannot do this. Whenever you do a AddHandler you should also do a ReleaseHandler (in this case in your form's Dispose) so that outstanding references will be removed.
