Summarize

Although spent a lot of time, but finally did not waste time, learned the knowledge. But obviously if I had known some of the knowledge of the underlying DLLs, it wouldn't have been a long time. Knowledge is efficiency. But it's a skill to be able to quickly understand your problems in a short period of time.
