Hi,
I have a strange problem with my xml file. In the schema of this xml
file I have set one column to autoincrement. When I enter the data in
my xml file directly, the autoincrement-column gets its correct
values.
Now I want to add new data with the help of a dataset. I use the
following lines of code:

I have set a DataTable and one of the columns I set "AutoIncrement" to True.
I then populate the Table by setting the columns to values then add the row
to the table. I inadverently set the AutoIncrement Columns to different
values but didn't get any errors. Should I be able to set the value of an
AutoIncrement Column? I would have thought it couldn't be done as the column
value was set when a row was added.

context: vb6/ ado / .mdb format / jet 4.0 (not using Access - ADO only)
- creating tables via ADO (don't have access)
- all tables have a primary key (PK)
- many of the PK will become FK(Foreign Key) in other table(s)
- record entries will be made via ADO
I am soliciting opinions on the pros and cons of using AUTOINCREMENT
versus code generated GUID or LONG value

What is the diffeence bewtween a dataAdapter.InsertCommand and
dataAdapter.SelectCommand (and dataAdapter.UpdateCommand for that matter)?

da.SelectCommand.CommandType = Command.Text

Hello All, I could use some help on an error that is just now popping it's
head up.
Seems that the autoincrement numeric has hit 32,767. The autoincrement is
used in various locations in the database, but in this case (log sheets), we
have hit 32k log entries over the past 2 years.
Is there a simple switch to set the autoincrement from integer to long
integer?

I can read in an SQL table ("Person.Contact") from AdventureWorks and step through it one row at a time, but when I try to save a record, either one I'm inserting or one I'm editting, I get the following exception:
Incorrect syntax near ','. Must declare scalar variable "@ContactID".
Here's the code:

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...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Hello
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.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
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...
