如何使用OLEDB或ADO连接获取Access DB的“扩展属性”

Question

I am trying to access MS-Access DB extended properties like Author,Owner, Last Modified Date, Last Accessed Date etc. using vb.net.

Please help me on this issue...

You can access/create/modify different types of properties.

at the database level

1. Some of them are specific to the Access database object / Access mdb file and can be managed through JET engine only / DAO database object. Please see the "createProperty" method in VBA/Access Help.
2. Some properties are available at the database level through the ADOX object, and can be accessed through an ADO connection, as long as the connection provider supplies these properties: dateModified and dateCreated should then be available at the table\\view\\proc level.
3. When manipulating DAO recordsets (not ADO ones), some extra properties are available at the recordset level, like "lastUpdated" or "lastModified".

At the file level

4. Some of them are specific to the fileSystem object, available with VB. They are available at the file level only
5. You can manage\\define extended properties at the file\\document level through the DSOfile object (please google for more details). Such object will allow you to add as many properties as needed such as "Title", 'Author", "Subject" , etc.

So, depending on the kind of property you need to access, these might not be available through an ADO connection.
