Normally when I use the Adaptor update function and it work fine but
sometimes I get a "duplicate entry" error after the merge. I believe the
problem is because the primary key is modified and the merge function is
unable compensate for this event. I see three possible solutions to this
problem. One being not to let them update the key which is not an option.
Two being to determine if the key has changed and refilling the entire
dataset...

A particular column in my Access DB table, and the associated datagrid,
cannot have duplicate string entries. I've selected "Yes (no duplicates)" for
the Indexed Field Property of this column in the Access table.
When I call update(), the DB gets updated but throws an exception saying, in

How do I handle this? How do I stop the ex.message being thrown?
I guess I...

Hi all,
Would someone be able to tell me the most 'graceful' way of removing
unwanted rows from a dataset based on a condition prior to update? OR,
resetting the rows all to unchanged after they are initally added to the
recordset.
I create a dataset, which begins empty after the initial .Fill.
Then I create several rows with some default information, leaving one

Still working out a few bugs in a survey program I'm writing. The way I
have it configured is as each survey is completed, the dataset is updated.
When the program is closed, the database itself is updated. However, when I
check the database table, there are some answers that are duplicated two and
three times.
Here are some snippets...

Hello,
How would I remove duplicate rows from a dataset after it has already been
populated?
What would be the best way to check each row and delete duplicates while
leaving at least one unique of the duplicate rows?
Any Ideas?

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
