Hi,
Please follow the following Steps,

1. Projet menu -> Refences -> Select Microsoft ActiveX Data Objects 2.1 Library and click ok Button.

2. Use the following code,

Dim con As New ADODB.Connection
Dim rs As New ADODB.RecordSet

con.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\UserLogin.mdb;Persist Security Info=False"

con.CursorLocation = adUseClient

rs.Open "Login",con


<<Here, Your database access code>>


rs.Close
con.Close

Here,
D:\UserLogin.mdb -> DataBase Location
Login -> Table Name

Note:
After finishing database access code you must close RecordSet(rs) and Connection(con).

Take Care,
Bye... Bye...
