Hello all, Please suppose I have a function that accepts a pointer as a parameter. This function can throw an exception, as it uses std::vector<>::push_back() to manage the lifecycle of this pointer. If I declare it like this: void manage(T *ptr); and call it like this: manage(new T()); if it throws an exception pushing the pointe...
I want to learn c++ as I will be working on image recognition, etc. I have a few years solid experience in C# and I have made stuff with C# so I'm not lacking experience. What is a good book which will help me make the transition (I will still be doing C# as it is my main skill)? Also, would you agree that to be good at C++, a lot of e...

Now i'm tryting to do the same in linux, creating a .so fil...
I am trying to create a simple visualization of what my code does. I am making a Poisson-Disk-Distribution class to generate a set of random points in a bounded rectangular region. Basically, what it does is it randomly generates a specified number of points in the bounded region and makes sure that each point is at least a certain dista...

I am trying to use a global shell hook to listen for windows created and destroyed events, but it seems as though my program is only registering the destroyed event for the local thread. No creation events at all, and definitely not the global events that I think they should be. I have spent the last day scouring the googles as well as ...
Currently, I am using a type-safe enum class from Boost Vault : http://stackoverflow.com/questions/217549/which-typesafe-enum-in-c-are-you-using I found it is difficult to have a parent class pointer to refer to all enum class, due to Boost::enum is a template class : boost::detail::enum_base<T> I am using void fun(const boost::any& a...

I'm looking for a C++ library that can parse 32-bit and 64-bit Mach-O binary format. I don't need anything fancy, just a disassembly and splitting the file into its sections, so no decompilation, name demangling and so on. I know I can either rip open any existing disassembler or craft my own binary parsers using the format specificatio...

Just curious. If you had the time and inclination to create a programming language, what characteristics would it have? One language I would like to see would borrow as much from the syntax of Python as possible but compile to machine code that runs as fast as C or C++. ...

I have a COM function that should return a SafeArray via a LPSAFEARRAY* out parameter. The function creates the SafeArray using ATL's CComSafeArray template class. My naive implementation uses CComSafeArray<T>::Detach() in order to move ownership from the local variable to the output parameter: void foo(LPSAFEARRAY* psa) { CComSafeA...
