Anonymity and Privacy / Re: VPN connection problem
« on: October 03, 2013, 01:01:48 pm »
I used Ultrasurf in old days, when it was not blocked. And also the same problem happened at that time too when it was not blocked. and i guess when i use vpn my ipaddress is changed and main server of my college logs me out when it finds different ip address .

Anonymity and Privacy / VPN connection problem
« on: October 03, 2013, 12:03:53 pm »
As most of the proxies do not work in my college .(Cyberoam is used in my college and everytime i access the internet , i have to login with my username and password ). So, I tried to use VPN . But now there is one more problem after every 10 minutes my connections are lost and i have to login again and again after every 10 minutes. So, tell me why do this happen? and what should i do so that i could connect to internet as long as i don't log out .

C - C++ / Re: problem with inheritence in c++.
« on: April 08, 2013, 07:20:06 pm »1. Also I don't see any correct class usage. I think you are expecting the class members to pop up in global namespace.I didn't get you actually. I have used object to call the member functions of a class at the last in void main same as above told by you. Am i wrong? If yes then tell me the right method.
2. That is wrong. Correct class usage is - MyClass myInstance; create a instance of the class. Then you would access the member function like this myInstance.memberFunction.

As for the error, I don't get the one you are talking about, what compiler are you using?
And yes, I fixed the "<*.h>" and "using * *;"

C - C++ / Re: problem with inheritence in c++.
« on: April 07, 2013, 09:25:05 pm »I tried compiling the program . Some of the errors were related to escape sequencing . Why would you do this ?I dont know about "using namespace std". I have never used . Can you please elaborate?
cout<<"\earth";
there is no \e escape sequence , a bunch of errors were like this .
Secondly
else(){} doesn't make sense to me
else if(){} is the correct way .
Third use#include <iosteam> not iostream.h
Fourth , use std::cout,std::endl,std::cin or "using namespace std;" before main .
Now I haven't run the program but it compiled properly , Nobody can help you with the inheritance problem or if the program behaves abnormally . You didn't mention what this program was supposed to do and what was the problem(after execution).
And p.s don't make a function inline when it is more than 3 lines of code , I see you've made a few functions inline which are like 30 lines long.
and i also dont know about inline functions, i got the inline function error many times but never understand what really it is?
