>In my app, I have a borderless, captionless 'form' that serves as the background in the main screen of my app. This form (form1) contains a few read-only textboxes and the application logo. I'd like to be able to call the refresh method of this form (form 1) from another form (form2). I'm not sure how to do this - any ideas?

Have you tried form1.refresh

Whenever I want to know how to reference an object, I just set a breakpoint where i want the reference to be then poke around in the locals window of the debugger.
