How to completely import an Access database to OpenOffice? I don't mean data, because that's easy. I mean data, queries, forms, VB code and so on.
You can't import all these elements in OpenOffice, but you can use Microsoft Access databases from within OpenOffice program. In order to do this you will need to use ODBC. Check the official web page where you can find the full instructions. If you have problems, I suggest you contact the support team.
