Seeing that Microsoft decided to take out the "Default" property of command buttons in the upgrade to .net, how do I set the default button without using "vb6." commands?

On a more general note, where can I find good information about the upgrade from vb 6 to .net? I have far too many questions that help and google can't solve to have to post out here every time, and anyway, it's certianly not the quickest way of getting answers (though it's quite useful).
