Hi,
I want to insert values into 2 tables Product_Table and Service_Centre_Table which are related to each
other by one to many relationship.Product_Table has S_Code which is primary key of Service_Centre_Table.
So first I am inserting values in the Service_Centre_Table.Before entering values in service centre table
I am checking if the details for that service centre already exist.If the details dont exist,only then the values
are inserted.Now,while entering values into Product_Table I am reading the S_Code value for the service centre from the database and then inserting it into the Product_Table.Values dont get saved to the Product_Table.I dont get any error.

 ElseIf ProductTypeComboBox.Text = "REPAIRED(INWARD)" Then
            Using sqlcon As New SqlConnection(My.Settings.Hardware_DatabaseConnectionString)

                sqlcon.Open()

                Dim sqlcmdscheck As New SqlCommand("SELECT count(*) FROM Service_Centre_Table WHERE S_Code=@scode", sqlcon)
                sqlcmdscheck.Parameters.AddWithValue("scode", Trim(ServiceCentreCodeTextBox.Text))
                Dim scount As Int32 = Convert.ToInt32(sqlcmdscheck.ExecuteScalar)

                If scount <= 0 Then
                    Dim sqlcmdv As New SqlCommand("INSERT INTO Service_Centre_Table([S_Name],[S_Address],[S_Cntct],[S_Cntct_Prsn]) VALUES(@sname,@saddress,@scntct,@scntctprsn)", sqlcon)

                    sqlcmdv.Parameters.AddWithValue("@sname", Trim(ServiceCentreNameComboBox.Text))
                    sqlcmdv.Parameters.AddWithValue("@saddress", ServiceCentreAddressRichTextBox.Text)
                    sqlcmdv.Parameters.AddWithValue("@scntct", Trim(ServiceCentreContactTextBox.Text))
                    sqlcmdv.Parameters.AddWithValue("@scntctprsn", Trim(ServiceCentreContactPersonTextBox.Text))
                    sqlcmdv.ExecuteNonQuery()
                    MsgBox("Data added to service centre successfully")
                End If
