方法二：
Access 系统表 MsysObjects 包含了数据库对象列表。尽管未在文档中记载，你仍可通过查询它来获取你想要的。但是默认情况下无法操作系统表，必须手动设定权限收才能查询系统表。
请参考以下动画：如何获取对msysobject的操作权限

警告：不要修改任何ACCESS系统表，否则会出现不可意料的情况.
使用下列 SQL 语句来获取你想要的
查询:
SELECT MSysObjects.Name FROM MsysObjects WHERE (Left([Name],1)<>"~") AND (MSysObjects.Type)=5 ORDER BY MSysObjects.Name;
窗体:
SELECT MSysObjects.Name FROM MsysObjects WHERE (Left([Name],1)<>"~") AND (MSysObjects.Type)=-32768 ORDER BY MSysObjects.Name;
表:
SELECT MSysObjects.Name FROM MsysObjects WHERE (Left([Name],1)<>"~") AND (Left$([Name],4) <> "Msys") AND (MSysObjects.Type)=1 ORDER BY MSysObjects.Name;
报表:
SELECT MSysObjects.Name FROM MsysObjects WHERE (Left([Name],1)<>"~") AND (MSysObjects.Type)= -32764 ORDER BY MSysObjects.Name;
模块:
SELECT MSysObjects.Name FROM MsysObjects WHERE (Left([Name],1)<>"~") AND (MSysObjects.Type)= -32761 ORDER BY MSysObjects.Name;
宏:
SELECT MSysObjects.Name FROM MsysObjects WHERE (Left([Name],1)<>"~") AND (MSysObjects.Type)= -32766 ORDER BY MSysObjects.Name;
