I need a bit of a hand here. I was a connection to a live database.
It is being displayed in a data grid
I'm using a dataset to grab the changes.
Once the modifications are done, how do I send all of those changes to the
database.
If you know how to accomplish this, I could really use a hand.
thanks.

If i delete e record through the dataView ,the record is deleted in the
underlying dataset, but when calling the dataadapter.udate method the
database is not updated.(altough the record is deleted from the dataset )

I'm not sure that I entirely understand the purpose of the
AcceptChanges methon in a DataView. I added a new record to a DataView
and noticed that its RowState indicated it as being "Added". If I
execute the Update method on an adapter for the table that the DataView
is based on, the new record will indeed be written to the database. But
if I call AcceptChanges prior to executing the Update method, the
RowState for the new record is...

Hi Guys,
I have a situation where I have a grid loaded with data. It is not data
bound. Clicking an image opens up another form that allows the change of
the data in the grid.
Right now the changed data (1 row) is written to the DB and the whole
grid is reloaded from the DB which now incorporates the change.
My question is can I update the data in a data view? That way I can

Hi all,
does anyone know if I can create a dataview
from multiple datatables. My dataset is constructed
from four separate tables and then the relationships
are added that link the tables together. To make
data entry easier I would like to combine selected
columns from the four tables onto a single dataview that
could be used as the datasource for a datagrid
control. The distinct updates, insert ans delete

Is there a way to call DataAdapter.Update from a Dataview when I have no
reference to the DataAdapter?
i.e. The DataView is a class variable however the dataadapter is a local
variable in a sub procedure. From another sub procedure is it possible to
call a dataadapter.update or similar?
Psuedo code is as follows:
Dim _dv as dataview

In the past, I have filled a datagrid with data from an Access database
table using a data adapter and dataset, where I used the OleDbCommandBuilder
to have the program create the insert, delete and update commands
automatically for the dataadapter. I think those database tables had no
more than 10 or 12 fields. Then to save the changes in the datagrid to the
database, I simply evoked the dataadapter update command. No problems.

I keep getting a concurrency exception the second time I make a change and
attempt to update a dataadapter. It appears this is by design, so there must
be something I can do to avoid it.
Example:
I have a dataadapter that contains one table with one row. I change the
value of the 'FisrtName' column in that row from Jack to John. I call
..update on the dataadapter it goes through fine. Now I change that same
column in that same row...

Got a question about the side effect of DataAdapter.Update() and
DataTable.GetChanges().
Say I set up a DataTable and a DataAdapter in a class. Delete (Not remove)
a row in the data table and call the following method.
public void JobListDataTableFromAccessCommitChange()
{
System.Data.DataTable oChangeDataTable;

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
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...
