Hey guy i have only just started using Vb.net and having a issue with connecting to a access mdb database

it looks like it connects ok but i am getting a "property item is readonly vb.net" when u try to access any of the records

        Dim rs As New ADODB.Recordset
        Dim sql As String
        Dim count As Integer

        sql = "select * from [pointers]"
        rs.Open(sql, cnn1, ADODB.CursorTypeEnum.adOpenDynamic, ADODB.LockTypeEnum.adLockPessimistic)

        rs.Fields("stockid") = stockn.Text + 1

and this is the connection i am using

Option Explicit On
Module Module1

    Public DBFile As String
    Public Source As String
    Public cnn1 As New ADODB.Connection
    Public ShowExt As Boolean
    Private HasAccess As Boolean

    Public Sub connect()

        Dim rs As New ADODB.Recordset
        Dim sql As String

        DBFile = Application.ExecutablePath()
        If Right(DBFile, 1) <> "\" Then
            DBFile = DBFile & "\"
        End If
        DBFile = "posit.mdb"
        cnn1.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source= " & DBFile & ";jet oledb"


        Exit Sub
        MsgBox(Err.Description & vbCrLf & vbCrLf & "Failed to 'connect to database", vbCritical, "Error")
        Resume DBSafe
    End Sub
End Module

You'll probably need to specify the correct property....

    rs.Fields("stockid").Value = stockn.Text + 1

Also, since the advent of .Net, ADODB has been replaced by ADO.NET. See here for an overview of ADO.NET -> http://msdn2.microsoft.com/en-us/library/h43ks021(VS.71).aspx

HI awolarczuk,

Here is a sample that has helped others.
I would not use recordsets, move to datasets (almost the samething)
