OracleConnection no need to open connection to query a stored proc

Question

I discovered something I would it strange today. As I was looking at my colleague code, I found that when whe query a stored proc, there's no need to open the connection before the instruction dataAdapter fill.
here's the example
Public Function getCodeBiensNi() As List(Of CodeBiensNi)
Dim CodeBiensNis As New List(Of CodeBiensNi)
Try
Dim cursCmd As OracleCommand = New OracleCommand("b240004k.get_bdm_code_biens_ni_2", connection)
cursCmd.CommandType = CommandType.StoredProcedure
Dim param0 As New OracleParameter
param0.OracleDbType = OracleDbType.RefCursor
param0.Direction = ParameterDirection.ReturnValue
cursCmd.Parameters.Add(param0)
Dim da As New OracleDataAdapter(cursCmd)
Dim ds As New DataSet
Dim unCodeBiensNi As CodeBiensNi
da.Fill(ds)
' loop through the data set and display each table/row/column
For Each dt As DataTable In ds.Tables
For Each dr As DataRow In dt.Rows
unCodeBiensNi = New CodeBiensNi With {.bcbn_code = dr.Item("bcbn_code"), _
.bcbn_description = dr.Item("bcbn_description").ToString, _
.bcbn_date_debut = dr.Item("bcbn_date_debut"), _
.bcbn_date_fin = dr.Item("bcbn_date_fin")}
CodeBiensNis.Add(unCodeBiensNi)
Next
Next
ds.Dispose()
da.Dispose()
param0.Dispose()
cursCmd.Dispose()
Catch ex As Exception
Throw New Exception("Erreur d'interrogation dans code biens ni. " + ex.Message)
Finally
End Try
Return CodeBiensNis
End Function
connection is a private member that has a valid connection string but that's not open. ie. I didn't issue open.
I even was on debug mode and all the time the state of connection is close.
Although it work for store proc, it didn't work for simple SQL query. If issue something simple like "select 'toto' from dual", if I don't open the connection it doesn't work, it raise a exception.
someone know why? I'm just too curious about that. Try to google it but i can't find the right keyword...

Hi Vishal,
Get the URL of the document you want to open.
There are various API/FM  of DMS available for this.
You can use ACFexecute UI elemnet for opening the document ( lIke PDF, word etc )  with this URL{ Available with NW Ehp 1}.
or you can try using LinktoUrl element.
Warm regards,
Atul
