How do I fix "sqlconnection is undefined"?

I was trying to rebuild a site and got the "undefined" error on a code-behind page. I guess I was in too much of a hurry. However, I have no idea where to start to fix the error. The "myCommand" statement receives the same error.  I use visual basic. Below is the code behind.

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim IDfromSession As String = (Session.Item("IDSession"))

        Dim myConnection As New SqlConnection("Data Source=vcnsql90.webhost4life.com;Initial Catalog=finaosms_membership;uid=************, pwd=*******************")

        Dim myCommand As New SqlCommand("uspGetTargetAddress", myConnection)
        myCommand.CommandType = CommandType.StoredProcedure

        myCommand.Parameters.Add("@LoginID", Data.SqlDbType.VarChar, 15)
        myCommand.Parameters("@LoginID").Value = IDfromSession

        Dim TargetAddress As String = myCommand.ExecuteScalar()

        Response.Redirect(TargetAddress, True)

        End Sub
End Class

Are you importing the proper namespace in you class:

"Imports System.Data.SqlClient"

In the top of page declaration, import below namespaces:
Imports System.Data
Imports System.Data.SQLClient
