I have further questions. I would truly appreciate if you could take time to answer them.

1. I have successfuly retreive the value of "pass" filed from csv file. Now I also want the value from the "name" field. How? 

    Dim email As String = tx_email.Text
    Dim name As String
    Dim password As String
    Dim path As String = Server.MapPath(Request.ApplicationPath) & "\data\"

    Dim con As OleDbConnection = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & path & "; Extended Properties='text; HDR=Yes; FMT=Delimited'")
    Dim command As OleDbCommand = con.CreateCommand()
    command.CommandText = "SELECT name, pass FROM wholesale.csv WHERE email = @email"
    command.Parameters.AddWithValue("@email", email)
    con.Open()
    name =
    password = command.ExecuteScalar().ToString()
    con.Close()

2. I want to use | character in seated of ,(comma) to separatre each filed in the csv file. The csv file looks as below

name | email | pass
Zuke Oshiro | info@msn.com | password01
Tom Black | info@yahoo.com | password02

I think I need to edit the following line.
Dim con As OleDbConnection = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & path & "; Extended Properties='text; HDR=Yes; FMT=Delimited'")

How?
