I'm developing a Linux application that needs to save some sensible data in order to reload them when the machine reboot.
So I'm investigating on how to save somewhere my data and protect them.
(Obviously there will be always a possibility to crack it)
My goal is not to reinvent the wheel, so if there is a working solution, that's what I'm looking for.
Add a dedicated user for your application and set proper directory attributes. So other users can't see the directory and files, only root.
Use a simple scramble algorhythm just to make the file hard to read by a simple cat.
Never store passwords, and other sensible information in files.

How should i get it, by SVN?
Can i use Eclipse and its Subversive Team Provider add on to manage my changes?
Then if i make some changes how can i commit, who decide that my changes are friendly and good enough?
To be honest i want to try to contribute to some library, because of motivation that contribution provides me on learning C++ details.
I search and read a little about Boost, but i think it is too complicated to be a starting point.
Thus can you provide a path to start and become an open source library contributor?
Well, the very first step is to actually read the FAQ. That's always a good start.
Especially the "How can I contribute to development?" question.

I want to develope a firewall for Linux. I prefer C/C++ language.
Is there any simple sample code for writing a firewall?
Which libraries should I use?
Update: There are some firewalls for Linux, but I want develope a simple firewall for learning.
You can start by using the Netfilters API (http://www.netfilter.org/). I think it is a good starting point for packet filtering. I've worked a lot with this API in kernel space. I'm not sure if there is a library for user land, but I must tell you that it's pretty easy to develop something with netfilters in the kernel.
As an example, iptables use the netfilters API.

I am trying to make a standalone using c++.In my standalone I want it to track user's clicks,I mean which link does he/she clicks.I am trying to count how much time he/she uses a perticular site,like pageaddict(a firefox extension).
So any support..?
If you want to make a Firefox extension, you should be using JavaScript. In C++, you might make a sniffer, which could tell you from what site the packets you receive are from. But that would require quite a lot of knowledge and of time.

Here's what I am trying to accomplish.
I want program1 to create a shared memory segment where I store various arrays.
Then, I want program2 to read in the arrays and modify them.
This sounds pretty simple, but for some reason, I cannot find a single example online that shows how this is done. Every example I have found uses a single program (e.g the initialize, read and write are both done by program1).
If somebody can provide an example here, I'm sure this would be hugely beneficial for pretty much everybody that wants to use IPC in C++.
Boost.Interprocess has a guide for the impatient.

hey i need c++ program to edit windows registry
One good program is Regedit.exe. It is probably written in C++.
Qt has an excellent framework for editing registy - that is, QSettings. And for bonus points, if you happen to change your mind and go Linux, your code would still work, storing your data in .ini-style configuration files.
Take note that Qt is very fat for a C++ library, but also very functional. There's a crazy lot you can do with it. I also absolutely recommend it for GUI.
There are probably a thousand small C++ wrappers for registry access. Of course I wrote my own, too. See the class RegistryKey in my envvc program. It's only read-only access, but you'll get the idea.
