When an exception happens, as you know, it passes pContext to the SEH. Is there anyways to access the pContext in a Try/Catch? I guess I could have the exception class grab it when being initiated but that would only work for that class and not for every exception. ...
If it is known that an application leaks memory (when executed), what are the various ways to locate such memory leak bugs in the source code of the application. I know of certain parsers/tools (which probably do static analysis of the code) which can be used here but are there any other ways/techniques to do that, specific to the langua...

I am wondering how compilers on Mac OS X, Windows and Linux know where to find the C header files. Specifically I am wondering how it knows where to find the #include with the <> brackets. #include "/Users/Brock/Desktop/Myfile.h" // absolute reference #include <stdio.h> // system relative reference? I assum...
How do I get boost::bind to work with array subscripts? Here's what I'm trying to achieve. Please advice. [servenail: C++Progs]$ g++ -v Reading specs from /usr/lib/gcc/i386-redhat-linux/3.4.6/specs Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr /share/info --enable-shared --enable-threads=posix --di...
Dear StackOverFlowers, I've got a variable with a declaration that looks like boost::unordered_map< std::string, boost::unordered_map <long,int>, hashe::fnv_1a> _pl; I need to serialise this to a file and and deserialise later. Should I just do a nested loop or can i do something ultracool with boost::serialisation? Any help pointing...
I have the following code: #include <iostream> #include "boost/unordered_map.hpp" using namespace std; using namespace boost; int main() { typedef unordered_map<int, int> Map; typedef Map::const_iterator It; Map m; m[11] = 0; m[0] = 1; m[21] = 2; for (It it (m.begin()); it!=m.end(); ++it) cout << i...
I would like to convert a boost::asio::streambuf into a std::string. How do I do that easily? ...
Hi, I tried to do something like this: int& g(int& number = 0) { //maybe do something with number return number; } but it doesn't work. It has to be passed by reference. Thank you for any help. P.S. I think that "Related Questions" appearing once you type Title is a good idea, but I also think that they should be displayed only i...
I'm using XML to send project information between applications. One of the pieces of information is the project description. So I have: <ProjectDescription>Test & spaces around&some & amps!</ProjectDescription> Or: "Test & spaces around&some & amps!" <-- GOOD! When I then use Expat to parse it, my data handler gets ju...
What is the correct / appropriate English terminology for referring to the "current" object in C++. For example, say you are writing a comment in the body of the implementation of this: Thing Thing::operator+(const Thing& other) You have the variable name "other" to use for the other object, but what word / expression do you use to r...
I tried compiling the following code in Linux and VS 2008: #include <iostream> // this line has a ".h" string attached to the iostream string in the linux version of the code using namespace std; // this line is commented in the linux version of the code void main() { int a=100; char arr[a]; arr[0]='a'; cout<<"array is:"<<arr...
I'm making a firefox extension (nsACString is from mozilla) but LoadLibrary expects a LPCWSTR. I googled a few options but nothing worked. Sort of out of my depth with strings so any references would also be appreciated. ...
If you have a c++ project with several source files and you hit compile, which file does the compiler start with? I am asking cause I am having some #include-dependency issues on a library. Compiler would be: VC2003. ...
We have a mature Windows desktop application written in C++. The application's GUI sits on top of a windows DLL that does most of the work for the GUI (it's kind of the engine). It, too, is written in C++. We are considering transitioning the Windows app to be a web-based app for various reasons. What I would like to avoid is having...
I ran into a problem when calling std::partition on an empty container (std::list). std::list<int>::iterator end_it = std::partition(l.begin(), l.end(), SomeFunctor(42)); std::list<int>::iterator it = l.begin(); while (it != end_it) { // do stuff } If the list is empty, std::partition returns an iterator, that is not equal to l.end...
How can I interrupt a sleeping/blocked boost::thread? I am using Boost v1.33.1, upgrading is not an option. Thank you. ...
Assume I have a reliable UDP library, and want to tunnel arbitrary TCP connections over it. This is my current approach to doing so, but I feel that it may not be very efficient. Any suggestions are very welcome. Client establishes a reliable UDP connection to server. Client runs a local SOCKS5 proxy, which receives data from any app t...
