Closing Form

I know how to create a New form, pass parameters, and show it, but how about closing it? What is the best way to do it?

To close a form?

Me.Close()
closes the form you are coding in.

F.Close()
closes a form that you have a reference to (where F is the name of the form variable you have declared)

Thanks Iceplug.

I was wondering if I had to use Dispose or anything else, but that seems to work fine. :)
