SQLReader SQLStored Procedure always HAS rows???? Don't understand Need Help

I have a stored procedure I am calling to return resuts if there any to a
sqldatareader.

The problem I am having is my code thinks it is always returning results...

the While rdr2.read always passes and the rdr2.has rows is true even
if the stored procdure returns no results.

I have tested this by runing the stored procedure manually and it shows NO
results.

What could be my problem?   Here is my simple code and stored procedure....

Thanks,


*******   Code


                Dim cmd As New SqlClient.SqlCommand("R_GetSiphoned")
                Dim rdr2 As SqlClient.SqlDataReader
                cmd.Connection = cn
                If cmd.Connection.State = ConnectionState.Closed Then
                    cmd.Connection.Open()
                End If
                cmd.CommandType = ADODB.CommandTypeEnum.adCmdStoredProc
                cmd.Parameters.Add("@Siteid", CStr(dtnew.Rows(i).Item(0)))
                cmd.Parameters.Add("@Date", CDate("1/1/2010"))
                rdr2 = sqlCmd.ExecuteReader()
                While rdr2.Read
                    If rdr2.HasRows Then
                        dtnew.Rows(i).Item(j + 1) = "X"
                    Else
                        dtnew.Rows(i).Item(j + 1) = "O"
                    End If
                End While
