I need a handler....

I have two forms.
Lets call them FormA and FormB.

On formA I want a handler called NewRecipeLoaded..

When a certain button on FormB is pushed I want to raise an event on FormA
for NewRecipeLoaded.

I know on formB I want RaiseEvent NewRecipeLoaded.

But how do I declare this on FormA and how do I code the procedure?

Thanks for any help
