calling window.print() in another frame (on a different domain)

Question

Hello, I'm writing a c# web application. I have a framset that contains 2 frames: a header and a body. The header has a 'print' button where i want to print the content of the body. The problem is that when loading the body i set its source to a given URL, for example: document.all.body.src = "http://www.cnn.com"; when trying to print the body's contents i get an error - "document doesn't support this property or method" any idea? thanks, Dana
