C++ - Change Dns Servers for all interfaces

I need a simple C++ program, it will change dns servers for all network devices. Registry key of dns server is: [HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Tcpip\Parameters\Interfaces\--device--\Nameserver] "NameServer"="8.8.8.8 8.8.4.4" Dns servers are: 8.8.8.8 - 8.8.4.4 Single computer may use more than one device. Please apply this changes to all devices listing after \interfaces\ directory. --- Events: --> First event is checking [login to view URL] if connection is successful or not. We will change dns server only if pc can't access to Youtube. Because, this program will published to Youtube-banned countries. Display the screen #1 while checking youtube connection. Youtube connection checking events: - try to connect [login to view URL] on 80 port. - find in html code "[login to view URL]". because youtube-banned countries will display a html code already, means of that is every connection will be successful. we must find a code what will displaying only on youtube.com. - if you see "[login to view URL]", connection is successful. if you don't see, isn't successful. --> if connection is successful, display screen #2 (look at attached file). ? ? Don't change dns server. --> if connection isn't successful, display screen #3. ? ? Ask to user if he want to change dns servers or not. --> if user clicks to yes, change dns servers and display screen #4. ? ? Ask to user if he want to reboot or not. --> if user clicks to no, display screen #5. Please note that, checking [login to view URL] connection must take 5 seconds at least. reason of this is, user must understand what happening. if it will not take 5 seconds, this screen will be displayed about 0.5 sec. only. Program title: Youtube Unban I need to recompile it with VS2008. Please send the sources compliatable with Visual Studio 2008. I attached everyting that you need. Thank you very much. ## Deliverables I attached the screens.
