Looking at many books understand the truth of 80 and 20, in the face of reality, it is really cruel. I think a very simple control upgrade is busy for a afternoon. True laugh, many basic mechanisms for .NET's basic mechanism is still unclear, I am very confused, I don't know if these things should be included in the training. According to my personal experience, no one taught me, I have encountered problems, I think more, I don't know if I have given them to handle them, and I don't have a sense of independent solving problems. It is also my sorrow. So I decided to let them do it yourself from today, let them expose their own problems.
