I think this is the right group to post to, so here goes.
My problem is this, I cannot update the datarow to save my life. Been
on this for 2 days now, and still am no closer to figuring it out than I
was before. I'm basicly taking date from some text boxes, trying to put
them into a datarow and using that datarow to update the database, but
its not working. The btn_update is where I am sending the information
back to the addclient...

Hello,
I tried to update a row in a table by using the datarow and data
adapter. Unfortunately, it doesn't update.
I try finding that datarow and set it to "dr", I can see dr could be
just an instance of the row, but aren't linked to the table. Is that
why it doesn't update? If not, what is missing? Please help!!!

The .NET 2.0 documentation states the following:
When using a DataSet or DataTable in conjunction with a DataAdapter & a
relational data source, use the Delete method of the DataRow to remove
the row. The Delete method marks the row as Deleted in the DataSet or
DataTable but does not remove it. Instead when the DataAdapter
encounters a row marked as Deleted, it executes its DeleteCommand
method to delete the row at the data source. The...

by the user. The Form has a Label as well which shows the total cost
of all the items that are currently present in his cart. This the

I found this in MSDN:
"The BeginEdit method is called implicitly when the user changes the value
of a data-bound control; the EndEdit method is called implicitly when you
invoke the AcceptChanges method for the DataTable object."
But what about the other way around? If I call EndEdit is AcceptChanges
invoked?
Since trying some test code, it seems to be that way. I am still trying to

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,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....

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...
