I am attempting to create a simple recordset that would return the
number of duplicates that exist in a table with a single column. For
example if I had a table like the following:
ID Reference Amount
1 123456 1.00
2 123456 2.00
3 123 1.00
I would like to get the following result:

Hi,
I understand you must first remove the constraint. The following bit does
not work (where t is a DataTable). It gives a 'reference not set to an
object' error
t.PrimaryKey.Clear(t.PrimaryKey, 0, 1)
If t.Columns.Contains("MYKEY") Then
If t.Columns.CanRemove(t.Columns("MYKEY")) Then
t.Columns.Remove("MYKEY")

Using sample codes from msdn and code snippets from this group, I am
able to derive a custom listivew user control with column sorting and
up/down icons in the column header. It works fine except one small
problem.
Say column 1 reads "company name", when I click on the header it
becomes "company..." with an up icon on the right indicating the column
is sorted in ascending order. When I click on the 2nd column, the code
removes the icon...

Within the access environment, I have a table that I'd like to
-add a column
-place the record number of each record into that column
The autonumber is not working for me because I am importing a .txt file into access using a specification file. The table is created at this time. When these steps are performed by hand access prompts you with a ? to add an index / auto counter field. When I run this via a macro I have not figured out...

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'm a network technician in training and I need your help.
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...
