This is a follow-on question to http://stackoverflow.com/questions/2748866/c0x-rvalue-references-and-temporaries In the previous question, I asked how this code should work: void f(const std::string &); //less efficient void f(std::string &&); //more efficient void g(const char * arg) { f(arg); } It seems that the move overload...
I'm looking for independent implementation of boost/tr1 shared_ptr, weak_ptr and enable_shared_from_this. I need: Boost independent very small implementation of these features. I need support of only modern compilers like GCC-4.x, MSVC-2008, Intel not things like MSVC6 or gcc-3.3 I need it to be licensed under non-copyleft LGPL compa...
I have in Visual Studio 2008 a .NET 3.5 C# project that uses a dll compiled from a C# project (let's call it dll A). Dll A is using on his turn some C++ libraries. The problem is that when I encounter an error while calling objects from dll A, the application just closes, without showing any error. But I need to know what's the problem,...

Yea this is a dumb question... However in both of my C++ classes we did not do this at all (except for native libraries: iostream, iomanip, etc.)... My question is can anyone provide a link that gives the general explanation of adding libraries to C++? I do realize what what #include means; it's just I have no clue on the linker/direct...
I'm thinking of creating a drawing program with layers, and using GDI+ to display them. I want to use GDI+ because it supports transparency. The thing is, drawing lines to the DC is very fast, but drawing directly to a bitmap is very slow. It is only fast if you lock the bits and start setting pixels. Can I draw to multiple DC's in my W...
I'm planning on learning 3d game development for the iphone using a 3d engine, but because of lack of tutorials for the iphone I was planning on using C++ game tutorials and making the necessary changes. The problem is that I've had limited success when searching for things such as 'c++ 3d fps tutorial ' I dont really get anything usefu...

My main problem is that I am completely overwhelmed and haven't got the slightest clue where I should be starting. I want to learn programming because I really enjoy ...
Hi all, in C++, when you define a function which takes one argument, you have to define the data type of that variable: void makeProccess(int request) However, I want to implement a function which takes different data types rather taking statically defined integer type. void makeProccess(anyType request) How can I design a procces...
I was just musing about the number of questions here that either are about the "big three" (copy constructor, assignment operator and destructor) or about problems caused by them not being implemented correctly, when it occurred to me that I could not remember the last time I had implemented them myself. A swift grep on my two most activ...
