In order to protect software from being copied without licence, I would like
to use something like a key, which fits only to the current system. The
serial number of the CPU or the current operating system would be
appropriate. However, I do not know how to retrieve the information.
Could you help?

Hi, below is example code which demonstrates a problem I have encountered.
When passing a number to a function I compare it with a string's size and
then take certain actions, unfortunately during the testing of it I
discovered that negative numbers were being treated as if they were > 0. I
compiled the following on mingw compiler/dev c++/windows xp.
If I replace string.size() for a ordinary number it behaves as expected? I

I wonder if someone has any ideas about the following.
I am currently producing some reports for a manufacturing company who work
with metal.
A finished part can contain multiple sub-parts to make up the finished part.
The sub-parts can also be made up of sub-parts and those sub-parts can also
be made up of sub-parts etc etc.
All parts are contained within the same table and I have a seperate table

Hi all
I'm deciding whether to use the PK also as an account number, invoice
number, transaction number, etc that the user will see for the respective
files. I understand that sometimes a number will be missing, which is not a
problem for my purposes I don't think, but how would it be negative? Can
randomly created PK autonumber fields be negative? Any way for a PK,
autonumbered, *incremented* to be negative?
TIA

Hello-
I have a database that uses an auto number field type that goes out of
sync periodically. My customer gets a "cannot add record, number already in
use" error message. I dump the records into a new table starting at auto
number 1, and sequentially up to about 20,000. Everything is fine for a
month or two, then the auto number field goes berserk again. Do you have
any ideas what the client may be doing to cause this problem, or is...

I save a number in the table and want to get that number again, but the
number I get has lower precision than I expect. For example, when I divide
10/3 I get 3.3333333333333335 if the variable is of type Double. But saving
this result into a table with a column of type Double decreases the precision
to 3.333333333333333 , so when I get this number and multiply it 10 I do not
get that exact number which is 10.
How can I solve this...

Hi everyone!
I'm sure my problem is pretty easy to solve but I've been working on it for a long and my my brain is not working correctly anymore.
I'm working with an AS400 and I mhave to do an "interface" in Access. It's like a little system to make a production plan. It must get information about part numbers, description, set where the part number belongs, quantity of part numbers that the set uses, stock number(this is a text value, it...

This is about a technique to find the mod of a very large integer with a normal small integer.
I recently encountered this problem when I needed to compute the modulus of a very large number with a normal integer. I needed this in a C++ program running on a 32-bit UNIX platform. The problem was that the number was 28 digits long and no native datatype in c++ could store a number of that size.
(Eg: 1088263455689473669888943602 % 380)

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,...
