if(ball.x>=SCREEN_WIDTH)
{
ball.dx =-ball.dx; // dx is the ball''s direction on the x axis
}

//bla...

if(ball hits paddle)
{
if(KEYDOWN(VK_DOWN)) // add downward spin
{
ball.dx+= ball.spin; // you don''t have to change ball direction, it was changed above ^
}
}

//bla, do this for the other directions, etc

Hope that helped

just flip the angle around, but thats a simple way...
