This is so bizarre I hesitate to post it, but I need to get this working.
My code looks like this...
Private Const cmdTestResourcesSel = "SELECT * FROM TResources" & _
" WHERE Scenario =
@Scenario"
Dim cmdstr as String
cmdstr = cmdTestResourcesSel

Hi,
Have anyone ever benchmark the TableAdapter performance compared to
DataTable's Load method? I found out that the DataTable's Load method is
about 10x faster than TableAdapter's Fill method.
I used the same SELECT query and DataSet (predefined), for both test.
For the DataTable's Load method, we first need to create a DataReader.

Dear Group,
When I add a DataTable to a Typed Dataset, and a TableAdapter to the
DataTable, I am able to create methods to send updates directly to the
database (GenerateDBDirectMethods), however when my TableAdapter Fill SQL
contains a WHERE clause which looks up a field from another joined table,
the Fill works perfectly, but I cannot Insert, Update or Delete using the
TableAdapter.
Does anyone know why this is?

On a form, I have a datagridview.
This datagridview is constructed on a dataset filled by a tableadapter.
The table adapter do very well what it must do when filling dataset.
Insertions, modifications and deletions functions very well in the dataset.
But impossible to transmit modifications in ACCESS database. Impossible to
WRITE in database.
Here is the code for data transmission from tableadapter to Access database

I've included the needed tables in the DataSource. Those tables that are
bound to controls I can workwith. But how do you get access to the
DataAdaptors that are not bound?
me.Dataset1.table is a table with no Insert or Update methods.
pll.DataSet1.table has the Row, ChangeEvent, and ChangeEventHandler.
It seems like it should be fairly straight forward to use the DataAdapter
without binding it to a control. How do you do this?

I have a question / concern regarding the new suggested way of creating a
data access layer in an n-tier application. Typically, a web application
specifically, using the SOA (Service Oriented Architecture) approach.
At various sites such as 15 Seconds
(http://www.15seconds.com/issue/050721.htm) they advocate using the
TableAdapter wizard to generate the data access layer.
Describing the TableAdapter wizard, here is a quote from the...

I am using the dataset wizard in VS 2005. I am not finding events which are
similar to events available in the regular xxDataAdapters like the
RowUpdated event in the TableAdapter class. Do I need to code these?

I'm not really sure how to ask this question because I'm still getting my
feet wet with data access and VB.NET, but here goes:
To start off with, I'm using VB 2005 Express to connect to an Access database.
I have a dataset in which a parameterized query returns the correct result
set in the forms of a tableadapter and a bindingnavigator. In other words, I
can perform my query and see that the tableadapter and bindingnavigator
contain...

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
Here is the code in...

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...
