I'm writing a small program with the OpenSSL library that is suppose to establish a connection with an SSLv3 server. This server dispenses a self-signed certificate, which causes the handshake to fail with this message: "sslv3 alert handshake failure, self signed certificate in certificate chain." Is there a way I can force the connecti...

I have ran the program through "Instrument" - Mac OS X memory leak applicaton and it find only some minor leaks - the memory leaked was a couple of hundred bytes and the program continuously grows. Wh...
I would like to write an application like a netstat - to show all the active connections and the open ports respectively. The problem is that I don't know how to do it - I've done some network programming but in general it was some simple server-client packet and simple TCP and UDP packets sending/receiving. I looked at the netstat cod...
Please view this image of the crash after I choose to debug it in MVS2010: http://i48.tinypic.com/dr8q9u.jpg Here's the Game.h header that shows the Game class structure, and in the picture you will see the offending method that's causing the access violation (setBot(botInfo * b)). class botInfo; // Forward declaration class Game { i...
I have created a maths library that operates via templates, it allows the user to specify the size and type of the array within a class which is then used to create a maths vector of any dimension up to four. As soon as I went to create a colour class, it struck me how similar the vector and colour class are. Is there anyway in which I c...
I am trying to use c++ in an iphone app. I added the line #include <cstring> in one of my files. I get "error: cstring: no such file or directory". What do I need to do to get it working?

Hi everyone, I would like to know what tools, frameworks or libraries you would use, to spread your C++ application across multiple machines. Im searching for a way to create a framework/environment, in which a master-server can hand many seperated Jobs to different seperated clients, who give back their result on a special Job. The res...
I'm going to create a utility with GUI that will run on Windows operating systems. It should require minimum (or zero!) amount of additional libraries, files or DLLs to run because it will be executed from an installer. Because of this, i don't want to use .NET for it will require user to install .NET Framework. I know today, most of Wi...
I'm having problem with vector, (in the usage of push_back) but it only appears when using additional g++ flag -O2 (I need it). #include <cstdio> #include <vector> typedef std::vector<int> node; typedef std::vector<node> graph; int main() { int n, k, a, b, sum; bool c; graph g(n, node()); c = scanf("%i%i", &n, &k); ...

Hi, i'm a little stuck on getting a plugin to work. I need it to take a "src" parameter but I can't seem to make it do this. So i've basically got the npsimple basic plugin. It's probably something really silly i'm missing Joe ...
I would like to write something like this, which cannot be compiled: std::vector<A> as; std::vector<B> bs( as.size() ); std::transform( as.beginn(), as.end(), bs.begin(), boost::lexical_cast<B> ); But this is not working, so I created a functor which is doing this for me: template<typename Dest> struct lexical_transform { templat...
I have this c++ program that is doing a simple ping on a specified ip address. I am not into networking so i'm just using the system() command in c++ to execute the ping from a shell and store the results in a file, that's easy. The problem is that i want some dots to be printed on the screen while the system() command is being execute...
