I'm using boost::program_options and it suffers from the same as many other c++ libs, even std itself: It still uses C-style null-terminated strings, because nobody really likes the weak std::string. The method in question is: options_description_easy_init& operator()(const char* name, const value_semantic* s, con...
I'm using VS 2010, and I'm wondering how I can get my c++ program to read a file using standard input while debugging. I know how to do it from command prompt, but not when debugging. Basically I want it to read in a file with cin>> instead of me typing stuff - but in debug mode. ...
I have to program a simple threaded program with MFC/C++ for a uni assignment. I have a simple scenario in wich i have a worker thread which executes a function along the lines of : UINT createSchedules(LPVOID param) { genProgThreadVal* v = (genProgThreadVal*) param; // v->searcherLock is of type CcriticalSection* while(1) { ...

Hi, I want to see how my #include files be processed when Microsoft Visual Studio C++ compile it. As I remember, there is a compile option to inline all #includes and #define lines but I can't find it. I use MSVC 2005 sp1. Thanks. ...
I have a std::list of boost::shared_ptr<T> and I want to remove an item from it but I only have a pointer of type T* which matches one of the items in the list. However I cant use myList.remove( tPtr ) I'm guessing because shared_ptr does not implement == for its template argument type. My immediate thought was to try myList.remove( sh...
While making a little Pong game in C++ OpenGL, I decided it'd be fun to create arcs (semi-circles) when stuff bounces. I decided to skip Bezier curves for the moment and just go with straight algebra, but I didn't get far. My algebra follows a simple quadratic function (y = +- sqrt(mx+c)). This little excerpt is just an example I've y...
Is it possible to multiply a char by an int? For example, I am trying to make a graph, with *'s for each time a number occurs. So something like, but this doesn't work char star = "*"; int num = 7; cout << star * num //to output 7 stars ...
I've done all of the layouts and have most of the code written even. But, I'm stuck in two places. 1) I'm not quite sure how to set up the timer. Am I using it correctly in the gridwindow class? And, am I used the timer functions/signals/slots correctly with the other gridwindow functions. 2) In GridWindow's timerFired() function, I'm ...
Say for example i have the following code (pure example): class a { int * p; public: a() { p = new int; } ~a() { delete p; } }; a * returnnew() { a retval; return(&retval); } int main() { a * foo = returnnew(); return 0; } In returnnew(), would retval be destructed after the return of the funct...
Take the following code class A { }; class B : public A { }; class C : public A { int x; }; int main (int argc, char** argv) { A* b = new B(); A* c = new C(); //in both cases, only ~A() is called, not ~B() or ~C() delete b; //is this ok? delete c; //does this line leak memory? return 0; } when calling delete on...

Here is the code to add the Image to the ImageList: HIMAGELIST CreateToolBarImages(HINSTANCE hInst) { HIMAGELIST v_ImageList = NULL; // IMAGE_LIST v_Img; HICON h...

My question is what exactly is a subprogram and a method? Which one of them means a function, and what does the other mean? Thank you ...
It's late and I can't figure out what is wrong with my syntax. I have asked other people and they can't find the syntax error either so I came here on a friend's advice. template <typename TT> bool PuzzleSolver<TT>::solve ( const Clock &pz ) { possibConfigs_.push( pz.getInitial() ); vector< Configuration<TT> > next_; //error is ...
I need to do the following C# code in C++ (if possible). I have to const a long string with lots of freaking quotes and other stuff in it. const String _literal = @"I can use "quotes" inside here"; ...
Using a QListView, and QStandardItemModel, is it possible to display icons in the list view without displaying the associated text? QStandardItem is defined as so: QStandardItem ( const QIcon & icon, const QString & text ) So it seems to require a text string of some sort - I only want the icon displayed. If I use the following co...
