to refresh the data in the table so that the updated data is displayed
in the DataGrid. Here's how I am attempting this:

Hi,
If I want to programatically add rows to a DataTable, do I call
AcceptChanges per row? Or do I call AcceptChanges after all rows added?
TIA

I have pasted at the end of this message a small sample program I whipped up
to do some testing.
It's a form with a datagrid and two buttons. Each button clears the
dataTable that is the source of the dataGrid, and then adds five rows.
Button2 is the same as button1 just that it does this in a different thread

I fill a DataTable with search results, which take a very long time if
I first clear it. The values come from an object and I map them into
the corresponding table columns. I may have 65000 results. I iterate
through them, create a new row, fill it, and add it to the DataTable
for each interation. This works fine on the first search.

textbox and click a button and the results display in a datagrid. I
could use either dataset or datatable to read the data in then I make
the datagrid.datasource = myds.Tables(0) or mydt. Now what I want is to
be able to change the query and click the button again and get...

Ok this should be simple.
I made a form, added a combobox (for selecting items to edit, not for updating fields), several textboxes, a few checkboxes etc. On formshow it connects to my database, draws down the existing data, no problem. All the records in the datatable that were the result of a query, I could select from, and the other databound...

Running on VS.net 2005,
I am trying to copy rows from my datatable to another datatable in the same
dataset.
The schema would be identical.
I need to make the table name "forms" as I am passing this dataset to
function that expects a dataset with a datatable in it.

Good day Group,
I have a form with a datagrid and two buttons. On show button
datagrid is populated with a datatable and on
clear button datagrid is cleared. DataTable.Clear not only removes
all of the data from the DataTable, it clears the dataset as well.
Why datatable.clear sets dataset to 0 rows?
Thanks
Ian

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. ...
