' create a data adapter
Dim da As OleDbDataAdapter = New OleDbDataAdapter("Select * from Customers", myConnection)
' create a new dataset
Dim ds As DataSet = New DataSet()
----------------------------------------
right here is where it is throwing the error
' fill dataset
da.Fill(ds, "Customers")
--------------------------------------------
' write dataset contents to an xml file by calling WriteXml method
' Attach DataSet to DataGrid
DataGrid1.DataSource = ds.DefaultViewManager
End Sub
End Class

I do not have much experiece using Access in a VB.NET application as I usually use mySQL or SQL Server, but I am guessing that the problem lies in your connection string.

Check out www.connectionstrings.com to make sure that it is correct, and if so, the post back here with the actual exception you are receiving.
