我修改了问题



然后几乎可以肯定你的数据库是在早期版本的ACE或JET中创建的数据库引擎 - 以后的引擎无法打开某些版本。

检查数据库，并（在备份之后）使用Access或类似功能将其转换为最新版本。

Don't post this under Quick Answers - if you got the code from an article, then there is a "Add a Comment or Question" button at the bottom of that article, which causes an email to be sent to the author. They are then alerted that you wish to speak to them.
Posting this here relies on them "dropping by" and realising it is for them.

"i modifed the question"

Then it's almost certainly that your DB was created in an earlier version of the ACE or JET DB engine - some versions cannot be opened by later engines.
Check the DB, and (after backing it up) convert it to the latest version using Access or similar.
