Problems with DataReader and MySQL .NET connector.. Please Help!

[Teo]

Hi!!
I have been trying to fix an error I keep getting on my VB.NET code.
For some reason, I get an error saying "Invalid attempt to access a field
before calling Read()" everytime. As you can see in my code below, I created
the connection, connection string, etc and I opened the connection, executed
the reader and then called the datareader.read () before any variable
assignment below.
I keep getting that error and I don't know why! I am going crazy.
Please check my code below:

Dim login As String = txtlogin.Text
Dim pass As String = txtpass.Text

Dim strConn As String
strConn = "host=201.218.2 39.10; user id=acarsuser; password=xxxxx;
database=acarss ystem"
Dim conn As New MySqlConnection (strConn)
Dim SQLCode As String
SQLCode = "SELECT DISTINCT pilot_id,name, password FROM pilot WHERE name='"
+ login + "' AND password = '" + pass + "'"
Dim datareader As MySqlDataReader
Dim Cmd As New MySqlCommand(SQ LCode, conn)
Try
conn.Open()
datareader = Cmd.ExecuteRead er

datareader.Read ()

Dim userID As String = datareader("nam e").ToString
Dim userpassword As String = datareader("pas sword").ToStrin g
If userID = login And userpassword = pass Then
'Creo la conexion para notificar al DB que el piloto esta Online
Dim pilotID As Integer
pilotID = datareader("pil ot_id").ToStrin g
Dim strConn1 As String
strConn1 = "host=201.218.2 39.10; user id=acarsuser; password=xxxxx;
database=acarss ystem;PORT=3306 "
Dim conn1 As New MySqlConnection (strConn1)
Dim SQLCode1 As String
SQLCode1 = "INSERT INTO acars_pilot (pilot_id) VALUES (" + pilotID + ")"
Dim myCommand As MySqlCommand
conn1.Open()
myCommand = New MySqlCommand(SQ LCode1, conn1)
myCommand.Execu teNonQuery()
conn1.Close()
Me.Hide()
AcarsMain.Show( )
Else
'Aviso que el usuario no existe
MsgBox("The user and password you supplied is not on the system. Please try
again.", MsgBoxStyle.Exc lamation)
End If

conn.Close()
Catch ex As Exception
MsgBox("Connect ion to ACARS server Unsuccessfull. Please try again later." &
ex.Message, MsgBoxStyle.OkO nly)

End Try
\\

For some reason the data reader doesn't work at all.No records are returned
and I get no message as I have in the code.
Any suggestions?
Thanks,
Teo
