Hi, I am trying to setup a development environment for Linux C++ application. Because I'm limited to my laptop (vista) which provides essential office applications, I want to program and access email, word at the same time. I'd prefer a local Windows IDE. SSH to a company linux server and using VI doesn't seem productive to me. Even usi...

I am building a CD ripper application in C++ and Qt. I would like to parallelize the application such that multiple tracks can be encoded concurrently. Therefore, I have structured the application in such a way that encoding a track is a "Task", and I'm working on a mechanism to run some number of these Tasks concurrently. I could, of ...
Hello I am about to start a new personal project. It aims to be a pretty big one so I thought it would be a good idea to keep some sort of CVS. I have also read lot of interesting stuff about unit testing and I would like to include some system that automatically builds the project and runs a series of test after each check in. The cha...

Also, entity objects may themselves expose access to other entity objects, again new copies of objects are created. I'm trying to find a caching solution. I'm looking for som...
I'm having some trouble with Visual Studio 2008. Very simple program: printing strings that are sent in as arguments. Why does this: #include <iostream> using namespace std; int _tmain(int argc, char* argv[]) { for (int c = 0; c < argc; c++) { cout << argv[c] << " "; } } For these arguments: program.exe testing on...
I've seen people use size_t whenever they mean an unsigned integer. For example: class Company { size_t num_employees_; // ... }; Is that good practice? One thing is you have to include <cstddef>. Should it be unsigned int instead? Or even just int? Just using int sounds attractive to me since it avoids stupid bugs like these (b...
I compiled the following code as a shared library using g++ -shared ...: class Foo { public: Foo() {} virtual ~Foo() = 0; virtual int Bar() = 0; }; class TestFoo : public Foo { public: int Bar() { return 0; } }; extern "C" { Foo* foo; void init() { // Runtime error: undefined symbol: _ZN3FooD2Ev foo = new TestFoo()...
In Visual C++ 2008 Express Edition when adding forms all of the default handlers for buttons, check boxes, etc go into FormName.h by default. So when I do this most of my handler code now goes in the header, then I switch back to the "Design View" to see the form designer. Once I have any reasonable size interface going back to "Design V...
I'm trying to do some classic C development in Visual C++ 2008 that will modify the characters of a string like so: void ModifyString(char *input) { // Change first character to 'a' *input = 'a'; } I'm getting a unhandled exception when I try to change a character. It seems like I could do this in Visual Studio 6 or using gcc, bu...

Hi. I have an assignment about fftw and I was trying to write a small program to create an fft of an image. I am using CImg to read and write images. But all I get is a dark image with a single white dot :( I'm most likely doing this the wrong way and I would appreciate if someone could explain how this should be done. I don't need the ...

I'm considering the use of C++ for a personal project. I would like to make it platform independent (no Mono please, since some platforms don't yet support it), and that's why I considered C++. I have one doubt, however. I've grown quite fond of C#'s attributes, and I would like to know if I can use something similar in C++. Also, is i...

Is there a standard or common way in C++ to handle static strings that need to be set by gettext()? Here is an example using the answer to Complete C++ i18n gettext() “hello world” example as a base just changing the literal hello world to a static char* hws and char* hw. It looks like hws is getting initialized to the default English t...
