Hello all,
I have a DataTable which I am building column by column and adding rows
after each new column. The DataTable columns match the columns in my
database table. I'm building the DataTable first and I then want to roll
through the DataTable while in memory checking for errors and then commit
the rows to my database table (btw this is in ASP.NET). Is it possible to
have data in a datable before attaching at DataAdapter? I'm a...

I have an ASP.NET/VB app that updates values in a DataTable over the
course of about 3 different pages. On the way out of the first of
these pages, I explicitly build the DataTable from values in a
DataGrid, and set the PrimaryKey of the DataTable to be the first cell
in the grid (which is a UserID value). I then store the DataTable in
a session object, from which it is retrieved for subsequent pages.
All this seems to be working fine.

Hi,
If I want to programatically add rows to a DataTable, do I call
AcceptChanges per row? Or do I call AcceptChanges after all rows added?
TIA

I should preface this by saying I'm new to the whole data scheme in .NET,
having in the past only worked with direct SQL queries. And I would still be
working with said queries if this were not already a complete application
using the "correct" data access methods. :)
Basically, our situation is this. Every second, our equipment logs a piece
of a "strip" of data, 32 records per second. Obviously in a strip that is
about 3 minutes long,...

When my webpage loads the first time, I fill my datatable with records from
the DB and display them in my gridview. Once it loads, the user clicks on a
button and add records to the datatable, which also show up in the gridview.
When "Finish" is clicked, I'll insert the records into the DB.
Question: What's the best way to display the datatable (with the records
from the DB and the records that the user added through the page) into the...

Hello
I'm a network technician in training and I need your help.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
