Hi
I posted a question recently regarding problems I am having getting a
value from a list box to use in a query. I got a lot of help, for
which I thank you and it's nearly working! But I need a little more
help on one more point.
This is what i've got. I have code that hunts for updated
appointments in a public folder based on the order that happens to be
open (code fires on an on open event) This works fine and updates my

I would be grateful if someone had a minute or two to review my hash
table implementation. It's not yet commented but hopefully it's short
and idiomatic enough to be readable. Some of the code (i.e. the
get_hash function) is borrowed from various snippets I found on the
net. Thee free function could probably need some love. I have been
thinking about having a second linked list of all entries so that the
cost of freeing is in proportion to...

Hi,
I'm using GCC. Please could you tell me, what is the maximum number of
array elements that I can create in C, i.e.
char* anArray = (char*) calloc( ??MAX?? , sizeof(char) ) ;
I've managed to create arrays using DOUBLE data types, but when I try
to access the array, the compiler complains that the number is not an
INT, i.e.

Is the code below valid? Generally a value must be accessed
through the same type it was stored as, but there is an exception
for data stored through a character type. I'm not sure if that
applies in this case though:
#include <limits.h>
unsigned foo(void) {
static const union {
unsigned char str;

Hi,
I have a question about converting some of the data in my dataset but leave some data the way it is.
I have a hash and if the key is present and the Value of the Hash equals B it should convert these number but if B is not present the data should remain the same.
my output is that all the data is converted not in the only the cases were B is present.
This is the script i have

Is there a typical way to create a dictionary (or hash table) with two
values, instead of one?
Currently, my data structure is TWO dictionaries, each with matching
and fully sychronized keys. This allows me to have one key with two
values (one value in each dictionary). This is ugly code as the
dictionaries could get out of synch (due to a bug or something).

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...
