Events for a Form Created in Code

I have created a class which creates a form and puts a text box and buttons on it.  I've been able to hook up the buttons so that they work and can access the text box.  Now, what I need is to set up events for the form.  Specifically, I'm trying to set up the Resize event.  If I can understand how to do that, I assume that all the other events will be coded in the same manner.
This has all been learning experience for me.  I appreciate your help.
