Bouncing Ball

I'm trying to make a shape (RedBall), bounce around inside a frame on a form but I'm not sure how to make the IF statement. Any help appreciated.

This is the code I'm using at the mo

    If (RedBall.Top < 2400 And RedBall.Left < 3960) Then
            RedBall.Top = RedBall.Top + 30
            RedBall.Left = RedBall.Left + 30
                If (RedBall.Top > 0 And RedBall.Left > 0) Then
                    RedBall.Top = RedBall.Top - 30
                    RedBall.Left = RedBall.Left - 30
                End If
    End If
