C++: error when have private copy ctor with public assignment operator
Hi guys, Can one of you explain why the following piece of code does not compile? #include <iostream> using namespace std; class Foo { public: Foo() { cout << "Foo::Foo()" << endl << endl; } Foo& operator=(const Foo&) { cout << "Foo::operator=(const Foo&)" << endl << endl; } private: Foo(const Foo& b) { *this = b; cout << "Foo:...
SideBySide error on another computer with MSVC++ 2005 installed
I'm having some strange issues building and running a project on another computer. It's a side-by-side error. Usually the cause is that c++ redistributable is not installed on the machine etc. However in this case the project is compiled on that machine. MSVC++ 2005 is installed, the runtimes should be there (I installed the runtime ...
High CSwitch ("context switch") when using Boost interprocess code (on Windows, Win32)
Hi, I'm writing a multithreaded app. I was using the boost::interprocess classes (version 1.36.0) Essentially, I have worker threads that need to be notified when work is available for them to do. I tried both the "semaphore" and "condition" approaches. In both cases, the CSwitch (context switch) for the worker threads seemed very h...
C++ operator overloading, understanding the Google style guide
I am following a book to learn C++ (come from a python background). I've written this, which works: class CatalogueItem { public: CatalogueItem(); CatalogueItem(int item_code, const string &name, const string &description); ~CatalogueItem() {}; bool operator< (const CatalogueItem &other) const; ...
What's the meaning of (int&) conversion in C++
There are such code. float b = 1.0f; int i = (int) b; int& j = (int&)b; cout<<i<<endl; cout<<j<<end; Then the output of i was 1, and the output of 1065353216! It's a big surprise to me! So what's the truly meaning of (int&) conversion in C++. Any help or hints are very appreicated! ...
How to get the length of IStream? C++
Hello, I'm creating an IStream as follow: IStream* stream; result = CreateStreamOnHGlobal(0, TRUE, &stream); Then I have a CImage object that I save to this stream: image->Save(stream, Gdiplus::ImageFormatBMP); I need to get the size of bytes written to this IStream. How can I do this? There is no Length or something like this in...

Get a Win32 program request a debugger on startup?
Hello all, We have a C++ Win32 application which spawns, using Qt's QProcess (undoubtedly a wrapper for CreateProcess()), a secondary 'slave' program. Unfortunately, when debugging the system with Visual Studio 2008, the debugger does not autoamtically attach to the spawned process. I know it's possible to programatically trigger a de...

C++ program not moving past cin step for string input
I'm obviously not quite getting the 'end-of-file' concept with C++ as the below program just isn't getting past the "while (cin >> x)" step. Whenever I run it from the command line it just sits there mocking me. Searching through SO and other places gives a lot of mention to hitting ctrl-z then hitting enter to put through an end-of-fi...
Is it possible to use function pointers across processes ?
I'm aware that each process creates it's own memory address space, however I was wondering, If Process A was to have a function like : int DoStuff() { return 1; } and a pointer typedef like : typedef int(DoStuff_f*)(); and a getter function like : DoStuff_f * getDoStuff() { return DoStuff; } and a magical way to communicate wit...
What are some techniques or tools for profiling excessive code size in C/C++ applications?
I have a C++ library that generates much larger code that I would really expect for what it is doing. From less than 50K lines of source I get shared objects that are almost 4 MB and static archives pushing 9. This is problematic both because the library binaries are quite large, and, much worse, even simple applications linking against ...

How to Draw pixel data taken from the backbuffer back to itself ?
I'm working on a mobile application for Symbian 5th edition using OpenGLES. This application is a pretty standard 2D app, and I make no use of the DepthBuffer. I need to grab a snapshot of the display and then draw the very same snapshot back to the backbuffer. I'm using glReadPixels((GLint)0, (GLint)0, (GLint)nWidth-1, (GLint)nH...
