ADOConnection not found

VB.NET
-----------------------------------------------------
I can't access to my access database via ado.net.
When I type in :
ADOConnection adoConnection = new ADOConnection()
the keyword ADOConnection is underlined, and can't be found!!
So, what shall I do?
to import something??
I've looked at so many examples of database accessing with ado.net in the internet, but nothing works!!
Perhaps you could give me some examples, how i could access to an access db called login, with one table 'login' and there i want to update the field username where id = 3, for example!!!
thx for your help!

First off, your syntax looks a bit like C++/C#; you can't declare variables like that in VB.Net. Can you?

Second, I don't know if there is an ADOConnection object in ADO.Net I've never seen it, but then again, I'm very new to .NET

The example below might start you off:

VB Code:

Imports System.Data.OleDb
Public Class DataAccess
 
 
    Public Sub test()
        Dim cnn As New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\test.mdb")
        Dim cmd As New OleDbCommand("SELECT * FROM tblPlayers", cnn)
        Dim da As New OleDbDataAdapter()
        Dim ds As New DataSet()
 
        'open the connection
        cnn.Open()
        'set the dataadapter command
        da.SelectCommand() = cmd
        'fill the dataset
        da.Fill(ds)
        'write out the data to prove that we did something!
        ds.WriteXml("c:\test.xml")
        'close the connection
        cnn.Close()
        'clear up all those objects
        ds = Nothing
        da = Nothing
        cmd = Nothing
        cnn = Nothing
    End Sub
 
End Class
