Hi all, I've got a strange problem with a static variable that is obviously not initialized as it should be. I have a huge project that runs with Windows and Linux. As the Linux developer doesn't have this problem I would suggest that this is some kind of wired Visual Studio stuff. Header file class MyClass { // some other stuff he...
Hello All, I'm using BoundsChecker9.1 with visual c++. I have a class class Sample{ public: vector<AnotherClass> x; }; When I run my program the BoundsChecker tool reports all push_back() calls such as S.x.push_back(AnotherClass()) as memory leak.. Wouldn't all the elements in vector x will always be deallocated when the Sample clas...

Possible Duplicates: When to use new and when not to, in C++? When should I use the new keyword in C++? It seems like I could program something without ever using the word new, and I would never have to worry about deleting anything either, so why should I ever call it? From what I understand, it's because I would run out o...

I'm trying to optimize some bit packing and unpacking routines. In order to do the packing I need to calculate the number of bits needed to store integer values. Here is the current code. if (n == -1) return 32; if (n == 0) return 1; int r = 0; while (n) { ++r; n >>= 1; } return r; ...
Would it be smart to have a vector in an object with a list of pointers that point to it? This way when the object is deleted, it could delete all the pointers pointing to it to prevent a null-pointer exception? ...
I'm looking for a HashTable or Dictionary implementation in C++ that has similar functionality to the one in C#? Does the STL contain an object like this and how would I use it? ...
This is for the purpose of a client/server program. The client asks for some data off the server, and receives it. Upon receiving this data from a Boost socket on the client side, I handle this message in a static method called parse_message in a class called client_protocol. This method, given this specific data, will start a process o...

How do I setup/register a callback function, in C++, to call a function when there is data to be read from a queue?

Is there a way to make the compiler create the default constructors even if I provide an explicit constructor of my own? Sometimes I find them very useful, and find it a waste of time to write e.g. the copy constructor, especially for large classes. ...
I am attempting to create an overloaded unary - operator but can't get the code to compile. A cut-down version of the code is as follows:- class frag { public: frag myfunc (frag oper1, frag oper2); frag myfunc2 (frag oper1, frag oper2); friend frag operator + (f...
