首先，我试着尽可能的注释代码来节省你的痛苦…

代码说明：

First off, I tried to comment the code as much as possible to save you the pains I went through. These programs are pretty simple and are meant for demonstration purposes. As always, you should not put them into a production environment without full testing first! 首先，我试着尽可能多的解释这些代码来让你少走一些我走过的弯路。这些程序相当简单并且适合作范例。按照惯例，你不应该没有全面地测试就把他们置于开发环境中! 来源: http://www.codeguru.com/advancedui/ProcessMB.htm-First off, I tried to comment the code as much as possible to save you the pains I went through. These programs are pretty simple and are meant for demonstration purposes. As always, you should not put them into a production environment without full testing first! First, I am trying the tortuous path which many explanations these codes asks you little to leave as far as possible some I to pass through. These procedures are quite simple and the suitable cooperation model. According to the convention, you should not not comprehensively test on set them in the development environment! Origin:
