you do NOT 'execute' an MDB file.  You use your VB program to read the data from the tables, and to write data back to the tables, or to use the Queries in the Database.

PhilAI is way off base, as the Shell function has NBOTHING whatsoever to do with using an Access MDB from a VB program.

In you VB Program, you can use either of two Data Access Technologies:

DAO - Data Access Objects, uses the JET engine, and is design for use with Access Databases, but is OLDER and 'obsolete' technology.  Microsoft is phasing OUT the on going support for DAO

ADO - ActiveX Data Objects - Uses OLEDB to connect to almost ANY data source (including Access), is the newest technology, and is Microsoft's approach to Universal Data Access.

With ADO: (Add a REFERENCE to the ActiveX Data Library - Project/References)

    Dim cn as ADODB.Connection
    Dim rs as ADODB.Recordset
    Dim strSQL as String

    Set cn = New ADODB.Connection
    cn.ConnectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=<Path to your database>;"
    cn.Open

    strSQL = "Select * from YourTable"

    set rs = cn.Execute(strSQL)

as a simple Example of getting data from a Table in an Access Database.

Hi Kelvsat,

Don't hesitate, go with Arthur_Wood. He is absolutely %100 correct. And don't touch DAO, go with ADO.

Declaration:

Private Declare Function ShellExecute Lib "shell32" Alias "ShellExecuteA" (ByVal hwnd As Long, ByVal lpOperation As String, ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long

How to use,

0& can be Me.Hwnd if you are using the function in a form

Call ShellExecute(0&, "open", "E:\database\MHclients.mdb", "", "", 3)


This uses the file association with MDB to open the file in MS Access

You question is a little bit unclear, but one of the comments above should give you the hint.

Let me add, that you can do everything with a MDB file without any need for Access itself. VB uses the MS JET Engine or ADO (newer) to control a Access database. So you can create / delete any object (tables, queris), read / write any data, add / delete users and so on. No need for Access as shell. The only exceptions it, that you do not have access to the Access forms or reports without opening Access. But you can replace this by VB Forms and the included report designer of VB.
