I am looking for a commercial-strength system that can provide me with product activation technology that is as convenient as possible for end users. Up until now I have been using the simplest system imaginable, where users get a key that is based on their name that they can use an unlimited number of times. This is more symbolic than anything else as users are able to pass their keys around freely, which they do. So I am wondering if there are any recommendations towards system that is well tested and widely used and works with C++ on Win32, but not cracked? I don't want to come up with a home made solution as I am no security expert, and do not have the time to learn the ins and outs of it.

I am developing a Windows desktop app, it allows users to create accounts and then login. Once logged in it allows them to interact with other users, and even has a chat box in a certain area. This app will eventually be ported over to android and ios(hopefully). Considering that it fetches quite a bit of information over the internet is C++ the most appropriate language to program it in?(i know quite a bit of c++, enough to make this) or should I use HTML5 or something else.
EDIT: For simplicity, essentially what I would like to know is. What is the EASIEST language to program an application in that will accept username/password and allow users to interact with one another. This program will also be accepting payments within it. I would like to use a language that is easily ported over to Android and IOS.
This is a question that doesn't really have a good answer. It's like asking what color you should paint the garden shed. There are many correct answers, and they are all subjective, and most likely based on the answerer's personal experiences.
If you have had experience with C++, then by all means go for it. C++ and it's related languages have the capability to create message windows and interact over the internet, so it is a good possibility for you.

I want to show a list of toll free and emergency numbers for different countries.
Is there any online API which provides me those numbers and regularly updates those numbers.
The list of Emergency numbers are available in wikipedia for all countries, but it would be nice if i can get those as a web-service.
Not Sure but i think you can use:
ro.ril.ecclist: list of valid Emergency Call Codes, for example, 911. Values are read from EF_ECC on the SIM and possibly supplmented by tables based on operator, network, or manufacturing code.

Since this post is over 3 years old now, I was wondering if anyone was aware of any open web services out there where live sports scores can be downloaded from.
Any demos or sample code would be great.
Thanks!
http://www.sportsdatallc.com/ is the best place I have found. They are expensive if you want realtime stats, but they have everything, and seem to be reliable.
If you want something free, then try ESPN APIs, but they do not yet offer score. They do offer team and player stats at the moment, however. I imagine they will eventually open up scores to the public.

I am new to cloud field, i want to know what it is from basic?
What are its advantages?
How it comes to use in real life?
Comparison with the existing technologies.
Cloud computing isn't a technology, it's a concept.
It means all your data (documents, photo's, music and even applications) is stored on a central server ('the cloud'). The advantage of this is that you can access your personal stuff from all your devices. If you want to listen to your music from a computer or some other device: no problem, since it's all 'in the cloud'.

I remember seeing some software applications demos before where they don't have any narration but just a background music played (no words, just the acoustic)...but i was never able to know the name of them. Any suggestions? It was pretty fast paced...or if you could kindly provide a link to some demo, I can try to search by voice...
Thanks
You might try http://www.ambientmusicgarden.com/. They have a lot of low-cost-royalty music which you can browse through based on several criteria. I first encountered them when the engineers at NASA did a really cool video montage of various launches and they used musci from there for their background.
