Hi,
If I want to programatically add rows to a DataTable, do I call

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.

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.

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.

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.

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.
