Alexander, I see that you are new here. I am happy to welcome you to this site and hope that you find much here useful. Also that you will be able to contribute much in the future.
However, it is considered bad practice to lock a question by posting an answer, see guidelines on https://www.experts-exchange.com/info/expertonly.html
especially when a satisfactory comment has already been posted. You give very little detail in your "Answer". Whilst using an access mdb is in some cases an acceptable technique, and DAO is a perfectly valid data access methodology.
The user may not wish to include the Jet engine and other components in the application. This adds a significant overhead to the footprint of the installed application and doesn't add anything over and above the functionality available using my method. Furthermore DAO will become obsolete in the future as Microsoft is likely to concentrate much more on the ADO technology as used in my example.
I would ask that you withdraw your "answer", feel free to add additional comments to this and other threads.

Should Alexander_Simons not withdraw his answer I would suggest that you reject it and ask for more information should my comment not be sufficient for you.

Your Code TimCottee doesn't work.
I have tried in another way, by using DATA objects, but if i run this code, it return an error
that the file doesn't exist, but it exist. In designermode i can do all perfectly, but in runtime
it occured always an error. (I am using DAO 3.6).
Maybe there is another option? I have to export data's into a DBF for older Programms,
maybe you know how i can make a DBF and make fields and insert data (it would be also possibility).
Data1.DatabaseName = "D:\Export\Kallg1.dbf"
Data1.Connect = "dBASE IV;"
Data1.RecordSource = "SELECT * FROM [KALLG1]"
Data1.Refresh
MsgBox Data1.Recordset.RecordCoun
MsgBox Data1.Recordset.Fields(0).

You have not said something about
ADODBC reference, with ADO 3.6 it doesn't work. First i have to remove reference to ADO 3.6 so the NEW statment works.
Thanks a lot.....

Now you can perform read/write/delete actions to the dbase4 tables by just using simple dao functions from vb to access the .mdb file !
