CR VS 2010 SQL query issue

Hi all

I'm facing a problem with my code.

Dim cr As New CrystalReport1()

Dim newCmd As SqlCommand

Dim conn As SqlConnection

Dim da As New SqlDataAdapter

Dim ds As New DataSet

Dim cr As New CrystalReport1

Dim MyConnectionStr As String = "Data Source=MyDB;Initial catalog=MyCat;Integrated Security=true;" ' providerName=System.data.sqlClient"

conn = New SqlConnection(MyConnectionStr)

Dim cmdText As String

cmdText= " SELECT customer.customer_name, customer.customer_tel, orders.order_stuff_name, orders.order_number" & _
" FROM hesabres.dbo.orders orders inner JOIN hesabres.dbo.customer customer ON orders.order_customer_id=customer.customer_id"

da = New SqlDataAdapter(newCmd)

da.fill(ds)

cr.SetDataSource(ds.Tables(0))

crystalviewer1.ReportSource = cr

conn.Close()

newCmd.Dispose()

if i run the query, let's say it returns 2 rows

I my CR veiwer, it shows 4 rows (duplicates 2 x 2),

if the query returns 3 rows, CR displays 9 rows (3 x 3) and so on 10 (10x10)....

How is it possible??

In my Dataset, the number of rows is always correct!

Do you have any idea?

Thanks in advance.
