I am developing a PHP-mysql database. It is noted that when the
browser window is refreshed the data is inserted again in the
database. unfortunately there is no unique keys that I can use to
verify the existance of the data, so as to prevent the multiple
insertion. Is there any other way to prevent it otherthan introducing
another field for this purpose and verifying its existance?
Regards,

Hello,
I am trying to build a dynamic set/list of data which should be sorted
as each element is inserted. The main criteria in this list is the
speed, the time it takes to insert a element, and the time it takes to
retrive it. Therefore I was wondering between STL Vectors, Maps, and
Set, what would be the most efficient way to do this, and how can it
be done easily.
Also, if I were to use STL Vectors, is there anyway that I can get...

Hello,
I have a report that returns a varying number of dollar amounts, depending on the date criteria that is entered. What I need to do is force a page break after 32 records and sum those 32. The next page should have remaining records up to 32 and sum those seperately from records on page one. What I've tried doing is putting a text box with =sum() in the page footer, but that gives me an error. Is there any way that I can do this? ...

Dear reader,
Is there some VBA code to place or remove a page break on the bottom of the
report header section?
In some cases only the header section of the report has to be printed in
that situation no page break is required and in other cases I need a page
break on the bottom of the report header section.

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...
