Violation or not!?

Two difference scenarios:

1) Offensive player in their front-court catches a pass at the top of the key, he goes to swing the ball to the wing, but realizes a defender is in the passing lane. He tries to stop his pass but it slips out of his hands and spills onto the floor. He takes two small steps and picks the ball back up. Violation or play on? Does he still have a dribble?

2) Offensive player in their front-court dribbles at the top of the key, picks up his dribble, goes to pass to the wing but the defender is in the passing lane. Tries to stop his pass but it spills out onto the floor. He takes two steps and picks it back up. Double dribble? No call?
