visual-c++-2010

While evaluating Visual Studio 2010 Beta 2, I see that in the converted directory, my vcproj files became vcxproj files. There are also vcxproj.filter files alongside each project which appear to contain a description of the folder structure (\Source Files, \Header Files, etc.). Do you think these filter files should be kept per-user, or should they be shared across the whole dev group and checked into SCC? My current thinking is to check them in, but I wonder if there are any reasons not to do that, or perhaps good reasons why I should definitely check them in. The obvious benefit is that the

I installed Open MPI 1.5.4 (64 bit) and I am trying to rebuild boost libraries (1.48) with bjam. I changed user-config.jam file, by adding using mpi line with explicit compiler path (although mpic++ is already in PATH environment variable): using mpi : "C:/Program Files (x86)/OpenMPI_v1.5.4-x64/bin/mpic++.exe" ; Then I tried to run from command prompt the following command: bjam toolset=msvc --build-type=complete --with-mpi --address-model=64 stage Unfortunately, the build process still needs more hints. Part of the error reporting looks like: MPI auto-detection failed: unknown wrapper

I hope some one can help me, i'm trying to create an int[400000000] (400 millions) array on my application using visual c++ 2010 but it generates an overflow error The same code runs on linux with g++. I need this because i'm working with large matrices. Thank you in advance. If you are using a 32-bit application then by default you have just 2GB of user address space. 400 million integers is about 1.5GB. You are very likely not to have this much contiguous address space. It is possible to force 32-bit windows to allocate a 3GB user address space for each process but this may just be a stop

I have the following: typedef std::function<void(const EventArgs&)> event_type; class Event : boost::noncopyable { private: typedef std::vector<event_type> EventVector; typedef EventVector::const_iterator EventVector_cit; EventVector m_Events; public: Event() { }; // eo ctor Event(Event&& _rhs) : m_Events(std::move(_rhs.m_Events)) { }; // eo mtor // operators Event& operator += (const event_type& _ev) { assert(std::find(m_Events.begin(), m_Events.end(), _ev) == m_Events.end()); m_Events.push_back(_ev); return *this; }; // eo += Event& operator -= (const event_type& _ev) { EventVector_cit cit

On Visual Studio 2010 under Windows 7, 32bit, unsigned long seems to be a distinct type from both uint32_t and uint64_t. See the following test program: #include <stdint.h> #include <stdio.h> template<class T, class U> struct is_same_type { static const bool value = false; }; template<class T> struct is_same_type<T, T> { static const bool value = true; }; #define TO_STRING(arg) TO_STRING_IMPL(arg) #define TO_STRING_IMPL(arg) #arg #define PRINT_SAME_TYPE(type1, type2) printf("%s (size=%d) %s %s (size=%d)\n", \ TO_STRING(type1), int(sizeof(type1)), \ is_same_type<type1, type2>::value ? "==" : "!
