        sqlUserName = "SELECT UserName,Password FROM UserName "
        sqlUserName &= " WHERE (UserName = @UserName"
        sqlUserName &= " AND Password = @Password)"

        Dim com As New SqlCommand(sqlUserName, Conn)
        com.Parameters.AddWithValue("@UserName", username)
        com.Parameters.AddWithValue("@Password", pwd)

        Dim CurrentName As String
        CurrentName = CStr(com.ExecuteScalar)
