Issues with classes again

Question

Hello again,

I have created a class, and two forms, and the "app" works like it should.  However, when I try to compile to a .dll it throws a Error  "Reference to a non-shared member requires an object reference".  This is exactly what Vulpes helped me with with an earlier project.  However, I just can't seem to get a firm grasp on using textboxes and other form methods and properties in another form.  I have attached the file for your reference.  Anf If someone could recommend a great way to learn(book, dvd, etc..) about how to use classes with multiple forms and their properties, I'd appreciate it.  I am bound and determined to learn how a class can be used on or with multiple forms.

Thanks,

Kevin
