Default how Insert record into two tables

I have two tables, that is tblProduct and tblPacking.
i write a stored procedure two insert data in two tables which is:

CREATE PROCEDURE sp_add

@ProId varchar(50),
@Pro_Id varchar(50),
@Composition varchar(100),
@Our_Brand varchar(100),
@Generic varchar(100),
@Cat_id int,
@Pack_id int,
@Strength varchar(50),
@Pack_Type varchar(50),
@Qty int,
@Price float(8)
AS
Begin
Insert into tblProduct (Pro_Id, Composition, Our_Brand, Generic, Cat_id) Values (@ProId, @Composition, @Our_Brand, @Generic, @Cat_id);
Insert into tblPacking (Pack_id, Pro_id, Strength, Pack_Type, Qty, Price) Values (@Pack_id, @Pro_Id, @Strength, @Pack_Type, @Qty, @Price)
End
GO


and my code is:

Dim objConn As New SqlConnection("server=(local); uid=sa; pwd=; database=cheapbrandpharmacy")
If Page.IsValid Then
            Dim objcmd As New SqlCommand("sp_Add", objConn)
        objcmd.CommandType = CommandType.StoredProcedure
        Dim objParam As SqlParameter
        Dim int As Integer = 0
        objParam = objcmd.Parameters.Add("@Pro_id", OleDbType.VarChar)
        objParam.Direction = ParameterDirection.Input
        objParam.Value = "CBP-" & txtPro_id.Text
        objParam = objcmd.Parameters.Add("@Our_Brand", OleDbType.VarChar)
        objParam.Direction = ParameterDirection.Input
        objParam.Value = txtBrand.Text
        objParam = objcmd.Parameters.Add("@Composition", OleDbType.VarChar)
        objParam.Direction = ParameterDirection.Input
        objParam.Value = txtComposition.Text
        objParam = objcmd.Parameters.Add("@Generic", OleDbType.VarChar)
        objParam.Direction = ParameterDirection.Input
        objParam.Value = txtGeneric.Text
        objParam = objcmd.Parameters.Add("@Cat_id", OleDbType.VarChar)
        objParam.Direction = ParameterDirection.Input
        objParam.Value = txtCat_id.Text
        objParam = objcmd.Parameters.Add("@Pack_id", OleDbType.Integer)
        objParam.Direction = ParameterDirection.Input
        objParam.Value = txtPack_id.Text
        objParam = objcmd.Parameters.Add("@Strength", OleDbType.Integer)
        objParam.Direction = ParameterDirection.Input
        objParam.Value = txtStrength.Text
        objParam = objcmd.Parameters.Add("@Pack_Type", OleDbType.VarChar)
        objParam.Direction = ParameterDirection.Input
        objParam.Value = txtPack_Type.Text
        objParam = objcmd.Parameters.Add("@Quantity", OleDbType.Integer)
        objParam.Direction = ParameterDirection.Input
        objParam.Value = txtQuantity.Text
        objParam = objcmd.Parameters.Add("@Price", OleDbType.VarChar)
        objParam.Direction = ParameterDirection.Input
        objParam.Value = txtPrice.Text

        Try
                objcmd.Connection.Open()
             int = objcmd.ExecuteNonQuery()
                objcmd.Connection.Close()
        Catch ex As Exception
            lblMessage.Text = ex.Message
        End Try

        If int <> 0 Then
            lblMessage.Text = int & "Record successfully added."
        Else
            lblMessage.Text = "No Record is added"
        End If
        End If
    End Sub

but the record is not inserted in both of tables.
Plz tell me what is problem in my code, I have great stress.

hey there.. do you receive any error?? or it just not adding the record???

also.. if you get an error you are not reading it because you are using the same label to display the error and the result...

lblmessage will ALWAYS display "No Record is added" regardless if an error is thrown or not. The reason is because int will always be 0 because:

int = objcmd.ExecuteNonQuery()

ExecuteNonQuery does not return a result set (why you didnt get an error is beyond me) and, further more, you don't have any stored proce varlabies set to Output. I think maybe you were thinking of ExecuteScalar but, again, you aren't returning a value so ExecuteScalar would be pointless.

hth.
