namespace AjaxTest
{

	public class Customer
	{
   	[Ajax.AjaxMethod()]
    public Hashtable GetAddressFromEmail(string Email)
    {
      Hashtable address = new Hashtable();
      address["success"] = false;
      //string sConnString = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source='" + @"C:\Inetpub\wwwroot\AjaxTest\Sales.mdb" + "';";
      string sConnString = "Provider=SQLOLEDB; Data Source='localhost'; Initial Catalog='sales'; User Id='Test'; Password='test';";
      OleDbConnection conn = new OleDbConnection(sConnString);      
      conn.Open();
      StringBuilder SQL = new StringBuilder("SELECT * FROM tblCustomer WHERE Email = '");
      string safeEmail = Email.Replace("'", "''");
      SQL.Append(safeEmail + "'");
      OleDbCommand cmd = new OleDbCommand(SQL.ToString(), conn);
      OleDbDataReader dr = cmd.ExecuteReader();
      Boolean found = dr.Read();
      if (found)
      {
        address["success"] = true;
