After much frustration I was able to update my data store via code only.
Using the data adapter was the only way I was able to set up all the objects
written in my code. Basically, I cheated by creating an adapter and then
copy, paste, modify it's code to suite my needs. This was the end result:
Private sub updateTable( )
Dim myData As DataSet
'Command is a form level oledbcommand object
Dim Adapter1 As New OleDbDataAdapter(Command)

I have written some code to manipulate data/records in a MASTER (order
header) and DETAIL (order details) tables.
What I have written is too extensive to post but essentially trying to:
1. Assign to a datarow (dr1) the first record of the MASTER table
2. Assign to another datarow (dr2) the second record of the MASTER table
3. If dr1.field1 = dr2.field1, then proceed, otherwise do stop
4. Assign to a third datarow (dr3) the first record...

Hi,
I have a large table. Normally, the user will need to see only the data
from the past two years, but sometimes, they will need to go back further.
I have a form with a datagrid, a DateTimePicker and a command button.
What I'd like is when the user selects a new date and clicks the button,
the grid would display data from the value in the datapicker through today.
I have it working, but only if I select everything in the data...

Hi all,
I am having a problem with my data adapter update command. I have
generated the data adapter in the IDE and then I built a dataset. The
dataset can get changed in the program and I would like to update the
database. I tried to do so using the update method of the data
adapter, but the table is not getting updated. While debugging I made
sure that the dataset has the correct value prior to calling the update
method. I think...

Hi All,

this I create a data table. Traverse in the original dataset & add
each row to created data table as it is through LoadDataRow method.

the row. After entire looping I fire the AcceptChanges method on data
table. After this I am trying to update this data back to database in

Hello,
I have a Dataset that I have table adapters in I designed using the designer

<System.ComponentModel.DataObject() attribute.
So, I drop a GridView on a webform and set its datasource to an

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp

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...
