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 just started with vb.net and try to use a tableadapter. I started with
draging my Pubs DB tables on the form so the dataset was created
automatically.
After I added a query with multiple tables and inner joins to one of the
adapters. displaying it on a Datagridview it also displayed me the
colummns (empty without values) not selected in the selectcommand.

I'm really confused here, and am wondering if someone knows what could
be the issue with my TableAdapter query.
A few months ago, I created a really neat program that has th ability
to search by a client account number. In the TableAdapter, I created a
new query called "FillbyAccountNumber". When I created this, I set up
the SELECT statement so that it selected all the fields I wanted and
then used the following WHERE clause:

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

XP & VB 2005 using the help files - followed instructions to use the
table adapter to delete a row from the database.
I step thru the table find the rows to delete and
issue a .Delete() and
after having done that for all the rows I want to delete
issue an AcceptChanges().
I get NO errors but the database is unchanged.
Google has several suggestions that seem very complex.
VB 2005 is supposed to be simple and direct - Not?
