I have a windows form that is bound to a datatable. In VB6
I could just update the field contents and it would be
updated in the database, however if I update the text
property of the control from code it is 50% chance that
the update will make it back to the dataset. If I update
the dataset instead of the form, it does not show on the
form.
Is there a method that should be used?

Suppose I add a new row to a table in a dataset, and then I use an
OleDbDataAdapter to add that new row to a SQL Server database using
OleDbDataAdapter.Update(), as in the following code:

dsLocalDataSet1.user_post.Newuser_postRow();
newRow.post_text = this.lblHiddenMessageStorage.Text;

Hi,
I have 1 dataset with 2 tables (Table1 as parent, Table2 as Child), 1 row in

update. But it also change the rowstate of the parent row from Added to
unchanged
When you try to save again parent row never get created in database. So
child update will fail again.
Please suggest what am I...

record to have the new parent ID. However when I do the update the changed
parentid in the child table fails to change. No error is given its just that

to be changed has a row...

I keep getting a concurrency exception the second time I make a change and
attempt to update a dataadapter. It appears this is by design, so there must
be something I can do to avoid it.
Example:
I have a dataadapter that contains one table with one row. I change the
value of the 'FisrtName' column in that row from Jack to John. I call

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:
