简单快速开发C\S架构程序用最简单的不分层最快的效率达到功能要求的例子程序FrmCommentAdd 添加评论的功能实现

其实系统里的所有的对象，就是加100个字段1000个字段，也是有描述不完的功能需要描述的，这时候我们其实还是希望有个可以对任何系统里的对象都可以进行评论的一个功能，这样任何想说明的，都能随时加个评论就可以了。这样方便系统里的多个用户之间沟通交流。其实很早就想做个这样的功能，但是由于一直没时间，就等到最近空了，才做了这个评论功能，打算对系统的所有的窗体都实现可以进行评论的功能改进。

程序里就用了SQLBuilder工具类的功能，代码编写简单，同时能支持多数据库的支持，将来有需要更换数据库时就不会头疼了。
