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

arrays - Algorithm to find ideal starting spot in a circle -

-
so problem have been debating such: your given array of integers representing circle. then, have pick spot in circle start. place start, compare value @ array number of steps took there , if steps less or equal number, include in final set. find place start have elements in set. ex, a=[0, 1, 2] if start @ index=0, then: a[0]=0 < =0 0 included a[1]=1 < =1 1 included a[2]=2 < =2 2 included final set: {0,1,2} if start @ index=1, then: a[1]=1 > 0 1 not included a[2]=2 > 1 2 not included here loop around a[0]=0 > 2 0 included final set: {0} if start @ index=2, then: a[2]=2 > 0 2 not included, here loop around a[0]=0 < = 1 0 included a[1]=1 < = 2 1 included final set: {0,1} so in trivial case, starting position index=0 best position results in final set elements. brute force method of finding obvious, trying find more efficient method. attempts far have been examine trying find max intersect of viable starting ranges calculated each element in arr...
