dotnet ado.net : Select and update
Hi all,
I'd like to do something that was very easy with ADO in VB6. I'd like to do a selection in one table and be able to search on the group of registers, update or even insert one new. This is possible to do in ADO .NET? How? Thank you in advance. Alejandro
Alenjandro,
Yes this is possible, however this newsgroup gives help, not complete code, that you can find in books or piece by piece on internet. The things you need are: a dataset/datatable a connection, a command and if you want to do it in an efficient way a DataAdapter By instance Bill has a nice book. It is so thick that you can use it as pillow, so you can sleep on it. When you read it, you will see it has more then the information you are asking for now. http://www.hitchhikerguides.net/ Cor "Alejandro" <alejandron@cibernos.com> schreef in bericht news:OBDUEHR9HHA.2752@TK2MSFTNGP06.phx.gbl...

Thank you very much Cor. I already know that books exist, but only I need a
small example. Does anybody know where I could find it or where I must ask?

Hi Alejandro
If you are after a basic example then these articles may be of interest: http://www.devcity.net/Articles/215/1/article.aspx http://www.devcity.net/Articles/240/1/article.aspx http://www.devcity.net/Articles/301/1/article.aspx They take you through the basics of ADO.NET and demonstrate how you can select and manage data from both an Access database and an SQL Server database.

Good articles, but I don't see any one that read and update (or insert) on
same selection. "David Jeavons" <djjeavons@gmail.com> escribió en el mensaje news:%23h5%23rNf9HHA.3916@TK2MSFTNGP02.phx.gbl...

Alejandro,
If you want to do the update easy like it was in VB6 then you can use the commandbuilder. samples on this site http://support.microsoft.com/kb/316758 Cor "Alejandro" <alejandron@cibernos.com> schreef in bericht news:eimqtFr9HHA.4200@TK2MSFTNGP04.phx.gbl...
