I need to use double data entry with an MS Access database. I have
read many arguments and reasons against this on this group but I have
to do this. I have seen various tips on how this can be done including
the use of queries but this hasn't worked satisfactorily. I have two
people who know Access just barely enough to enter the data so what I
really want is something like the msgbox function to pop up a window
whenever the person...

When I write 'double' data to the file, it seems working fine, but when
I read it later, it returns a eof when it encounters a particular
number even the file is not at the end yet. However, while I write a
different set of data, there is no problem to read it.
Attached is the file: try change the #define RANGE 1000 into 10000,
the code works when the number is 1000, and does not work when the
number is 10000.

Hello everyone,
I'm looking for some advice on whether I should break the
normalization rule. Normally, I would not consider it, but this seems
to be a special case.
I have created an "Outcomes Database" used to store response data
from measures/ questionnaires for a longitudinal health study. It is
essentially derived from Duane Hookom's Survey Database (thanks
Duane!!!), with many modifications added to fit the needs of my lab.

I'm building a bookings database for trucks that among other things
captures the TruckName, LoadDate, LoadTime, UnloadDate and UnloadTime.
Is there a simple way to prevent double bookings for any particular
truck so that when a new entry is being added, if the LoadDate and
LoadTime doubles up with an existing entry I can flag it to the user?

Hello All
I am using Microsoft Access 2003. I have an input form (Single Form) into which the clerk records appliance details. Some appliance details will never change, for instance the 'Make and Model'. Some details will need to be updated later on, for instance the location of the appliance. When updates are required, the user opens the update form (Single Form). The user is able to cycle through all records of appliances using this...

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...

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....
Now, this would greatly impact the work of software developers. The idea...
