I think that my first blog post would be useful for what you want to do. Although the post is about passing data between forms, the same ideas can be used for executing methods from one form to another. In your case, I think you should have a public method on Form1 that sets the enabled value of your CheckBox and the button handler on Form2 should call Form1's method.
