I'm trying to copy production statistics to a test database and can't
set the column statistics for a VARGRAPHIC column to match what RUNSTATS
generated on production.
The reason code and some testing I did indicates that the length of the
low2key value is too long. It almost looks like the potential length of
data to be stored is being calculated on the length of the hex string;
without consideration that two bytes of the string...

My understanding is that GRAPHIC and VARGRAPHIC data types can store
text encoded in UCS-2 in a Unicode database (ie when it is created so
that CHAR is encoded in UTF-8).
What is the encoding of GRAPHIC in a non Unicode database ? I have not
found any documentation that explains this clearly.
Thanks

I'm implementing a UDP server socket from the system.net.sockets.socket
class. (no, I don't want to use the udpclient class)
I'm polling the socket in a thread, testing the socket.available property on
each pass.
With datagrams, does socket.available only advertise when there are complete
packets in its buffers?
What i mean to say is that if socket.Available > 0 then there will be at
least 1 whole datagram ready to be read? So, if less...

Hi,
I try to implement a reusable socket class to send and receive data.
It seems to work but I have 2 problems :
1) I rely on Socket.Available to detect that the connection is closed (no
more data to expect). Sometimes, Socket.Available returns 0 but the other
end of the connection did not close it !
2) This class will be used by many other classes so I have to use the

Problem: How can I code up a client side process to detect if the
network is available?
Synopsis: I am writing ASP.NET input forms for a Panasonic Tuff book.
The users will be walking around the plant with a wireless connection.
There are some pockets of non-connectivity. I've been tasked with
disabling the submit button on the form if the network is unavailable.
Possible solution: I can instantiate a timed process (VB.NET 2.0

Hopefully someone will be able to help.
I have written a stored procedure in C++ called from a Java test
harness to validate the graphic data types in C++ and their use.
I have declared the vargraphic input parameters along the following
lines
in i_vargraphic100 vargraphic(100)
and they are populated from String's in java.

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

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,...
