Form Level Scope

When declaring / launching a new form a menu item, should the variable be set to module level rather than procedure, what is the best practice.

        _form = New ListForm()

or dim frm as form = new ListForm

if you do not need the reference to your _form from elsewhere then in the procedure, declare it local to the procedure
Mike Tomlinson

It might be useful to declare it at the form/class level if you want to keep an easy reference so you can allow only one instance of the form to be opened at any one time.

*They are others ways of doing this as well.
