In a program randomly generating 10 000 000 alphanumeric codes of 16
characters in length (Ex.: "ZAZAZAZAZAZAZ156"), what would be an
efficient way to ensure that I do not generate duplicates?
STL set, map?
Could you give me a little code example?
Thank you.

I need a program that generate 5 non-duplicates random number between 1-10
as string values store in an array.
Do anybody know of any good books or websites that explain how to generator
random numbers using asp.net? I know about the random namespace within .net,
but
I need a reference to some code that do the similar stated function above.
Plus If you have any coding practice ideas for the above defined project
please share them.

Hello all,
I am trying to generate random seeds for my simulations.
currently i was using srand(time(NULL); for this purpose.
But for confidence in my results i ran it using a script in a loop.
Since the time b/w execution is very similar, many simulation runs
resulted in exact same results.
Is there a better way of seeding the random number generator in c/c++

I'm building a web application using sqlalchemy in my db layer.
Some of the tables require single integer primary keys which might be
exposed in some parts of the web interface. If users can guess the next
key in a sequence, it might be possible for them to 'game' or
manipulate the system in unexpected ways. I want to avoid this by
generating a random key for each row ID, and have decided to use the
same approach for all my single key...

Howdy folks, was wondering if anyone could assist me in a better method for generating a alphanumeric sequence of 6 characters/digits. The method I am currently using gives me a random license plate number for a project I am working on. But I am unsatisfied with the results I am getting. Here is my current method, it works but like I said there has to be a better way of doing it.

int x = 6;

These are some "random" thoughts about generating random numbers in Visual Basic.
Wikipedia will give a better introduction than I, see http://en.wikipedia.org/wiki/Random_number_generator.
The key point is that you need to start the random number generator with a seed. Doing it in the form load with the number of milliseconds since midnight is an easy way to start.
The VB.Net version
This demo project will be as simple as I can...

What is the correct method for generating 2 independent random numbers?
They will be compared whether they are equal.
What about this method:
srand(time(0));
int r1 = rand();
srand(rand());
int r2 = rand();
bool f = r1 == r2;

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,...
