sql server - Update database using strongly typed DataSet -

-

i have database sql server 2014. made stored procedure selects several fields. until fine. returns datatable bind datagridview. problem when want update datatable. made stored procedure update. (my update works fine in sql server). reason when update visual basic, updated dataset not database! reason, looks not connect database.

i know can use sqlconnection.open() , sqlconnection.close() i'm working "disconnected ado.net" when call updatecommand, it's supposed connect directly database, didn't! doing wrong?

p.s. sorry bad english.

here part of code:

'initialize command command.commandtype = commandtype.storedprocedure command.commandtext = "dbo.update"  command.parameters.add(new sqlparameter("@idinventory", sqldbtype.int, 1, table.columns(0).caption)) command.parameters.add(new sqlparameter("@idproduct", sqldbtype.int, 1,    table.columns(1).caption)) command.parameters.add(new sqlparameter("@code", sqldbtype.nvarchar)) command.parameters("@code").sourcecolumn = "code"  command.connection = adaptater.connection  try     adaptater.adapter.updatecommand = command catch ex exception     msgbox(ex.message) end try
