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

Hi all.
I am developing some web application in which I use datasets, which
were generated using dataSetDesigner. My dataset has a TableAdapter,
which has GetData method. Users of my application sometimes get timeout
while executing this GetData method.
I would like to increase CommandTimeout for this GetData method, but I
cannot find this property. How can I do that?

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'm using TableAdapter with .NET 2.0 and SQL 2005.
In SQL Database, a column's type is "float".
Default TableAdapter methods update, insert, get, etc. maps this
automatically to c# type "double"
Question- Why is it when I create a new SQL Query, Insert Method,
all of a sudden the tableadapter is calling the variable "float" when
the default Insert method to tableadapter it is "double" ? What is

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:

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
