desprating!!!!!! 斑竹还有各位高手们请帮帮我！！

以下这个程序是关于在已有的文件夹里（new folder)的所有.txt文件的数据传到数据库之中，
每个txtfile的数据特征如下：
761526|ORIGINAL|2006-06-12|14:57:34|2T268765|26067|NO REG|CH276|STAGED|Order number 2T268765-1|
每个数据用"|"隔开。
传输完的文件之后转移到新的文件夹叫做"post archive" 我已经实现了运行一次就有一个文件的数据被读入数据库之中并且改文件夹的txt文件转移到新的文件夹（post archive）里面
但是我现在的程序不想让它有任何按钮，也就是说要是程序让它随windows一直运行，随时检测new folder里面有没有新的txt文件进来。如果有，就读取数据到数据库之中。如果没有就不运行。所以，“new folder”的文件夹必须随时保持更新。请各位高手们详细解答。可以的话帮我添加一下代码或者注释，真的非常感谢了。。。
以下是程序的代码，但是现在只是每运行一次只有一条记录被写入数据库，同时一个new folder的文本文件被转移到\“post archive\”的文件夹中，所以请帮忙添加可以自动不断的运行。使不断的数据添加到数据库中。
