Default Extract data out from datareader

Hi

I have a problem here. I want to extract the details out for preparation to email these details out. However, when I use the datareader, everything turns weird. Below are my codes, please advice.

Dim selectedDate As DateTime
        Dim selectedCompany As String
        'Dim htmlcodes As String

        selectedDate = ddlDateCreated.SelectedValue
        selectedCompany = ddlCompany.SelectedValue.ToString

        MsgBox(selectedDate + " " + selectedCompany)

        Dim dbconn As OleDbConnection
        Dim sql As String
        Dim dbcomm As OleDbCommand
        Dim dataAdap As OleDbDataAdapter
        Dim ds As DataSet
        Dim dr As OleDbDataReader

        dbconn = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; data source=" & Server.MapPath("App_Data/DB.mdb"))
        dbconn.Open()
        sql = "SELECT ID, acct, number, FullName FROM table WHERE comp LIKE '" + selectedCompany + "%'" + " and DateCreated LIKE '" + selectedDate + "%'"

        dbcomm = New OleDbCommand(sql, dbconn)

        dataAdap = New OleDbDataAdapter(dbcomm)


        ds = New DataSet
        Try
                    Ã‚  Â
            dataAdap.Fill(ds)
            GridView1.DataSource = ds
            GridView1.DataBind()

            dr = dbcomm.ExecuteReader
            While dr.Read
                Dim account As String = dr("acct")
                Dim empno As String = dr("number")
                Dim name As String = dr("FullName")

                MsgBox(account + " " + empno + " " + name)
            End While

        Catch ex As Exception
            MsgBox("No records found for " + selectedCompany + " and of date " + selectedDate, MsgBoxStyle.OkOnly, "No Records Found")
        End Try

the datareader always ends with exception error even though there is a record existing in the data base.

Please advice me on which part of the codes I'm wrong in.
Thank you
