SQL Server 2008中的DMF可以极大程度地降低管理成本，不过今天在学习DMF的配置时，我几乎吐血加厥倒。
原因是DMF的策略可以提供策略组的功能，用户可以选择订阅某些组的策略，一般策略都是属于Default组，而策略管理员可以创建一些策略组，并将策略放置到组中，以便于DBA选择策略进行应用。不过我屡次尝试都发现创建的策略组是无法订阅的，因为订阅的Checkbox始终是灰色的，在经历了疑惑、焦躁、愤怒和无奈后，最终发现了这个问题的症结。
为了避免大家也经历这种和MM分手时相类似的心理历程，贴图如下：
1、打开策略组的定义对话框
2、定义策略组
3、千万记得横向滑动列表框到底，天晓得这个后面还有一列，只有取消了Checkbox，这个策略组才是可以手动订阅的，默认有点类似于组策略中的强制策略一样。诶，微软的Dev为什么不把这列放到前面呢?!看来易用性的细节是无处不在啊！

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
