   Try
            Me.T_InventoryBindingSource.AddNew()
            Me.T_InventoryTableAdapter.Insert(iBarcode, iItemdesc, iRSP,      
                                   Val(iCount), CDbl("0"), "a", "a1", iItemcode)
            Me.T_InventoryTableAdapter.Update 
                                    (Me.SQL2005MobileDataSet.t_Inventory)

          
     Catch ex As System.Exception
             System.Windows.Forms.MessageBox.Show(ex.Message)
     End Try
