What are two Presidential ways you can veto the law?

He can veto a bill and he can "pocket veto" one. A pocket veto is when he does nothing and it sits on his desk for 10 days. At that point it is a veto. This is handy because the law maybe popular but he doesn't want to veto it, so he does nothing either way. In the last several years a third way has been used and that is a signing statement. The President signs the bill into law, but then signs a statement that it shouldn't be enforced. Bush did this with about 800 laws. I don't know if Obama has done any signing statements. This really got going under Clinton who did several hundred in his 8 years.
