Hello, I generated a DLL in Visual from a C++ code. Dependency Walker sees 3 functions exported as C functions. I made an SCons project to do the generate the DLL, and 2 of the 3 functions are not seen as C functions. What makes a function seen as a or C++ function, without modifying the code ? It must be in the compilation/linking op...
class X { protected: void protectedFunction() { cout << "i am protected" ; } }; class Y : public X { public: using X::protectedFunction; }; int main() { Y y1; y1.protectedFunction(); } This way i am able to expose one of the function of base class. Doesnt this violate the encapsulation principle is there a specific r...
I am using the latest flash player and have a swf file served locally from my dev machine. In one container test app I am able to play the swf and make calls to it, but in my "Real" application the same code path results in com errors (basically it looks like the swf isn;' loading properly) Additionally this is made more challenging be...
Hi there, I am a programming student in my second OOP class, and I have a simple question that I have not been able to find the answer to on the internet, if it's out there, I apologize. My question is this: Is it possible have Boolean conditions in switch statements? Example: switch(userInputtedInt) { case >= someNum && <= some...
I'm running OSX 10.6 (Snow Leopard), Qt 4.6, VTK 5.4, and Cmake 2.8. I installed Qt, then VTK and Cmake. I configured VTK to use QT 4.6 (turned on VTK_USE_GUISUPPORT and VTK_USE_QVTK). The configuration and installation worked painlessly but if I run Cmake with Qt references the compilation fails during the subsequent make process becaus...
I have code that compiles fine with VC9 (Microsoft Visual C++ 2008 SP1) but not with GCC 4.2 (on Mac, if that matters). If I pile on enough qualifiers and keywords I can force it to work in GCC but this doesn't seem right. Here's a minimal code sample exhibiting my problems: template< typename N > struct B { typedef N n_type; ...
Possible Duplicate: Why does C++ compilation take so long? Hi, I searched in google for the differences between C++ and Java compilation process, but C++ and Java language features and their differences are returned. I am proficient in Java, but not in C++. But I fixed few bugs in C++. From my experience, I noticed that C++ a...
I am going to start a new C++ project that will rely on a series of libraries, including part of the Boost libraries, the log4cxx or the google logging library - and as the project evolves other ones as well (which I can not yet anticipate). It will have to run on both 32 and 64 bit systems, most probably in a quite diverse Linux enviro...
Hi, I want to test the rendering of a configured vhost before the hostname is set. Exemple : view the webpage "otherNameOfMySite" located at mysite.com if the dns entry "otherNameOfMySite" doesn't exist (but the apache vhost is set). My code : webvhost = new QWebView(); QNetworkRequest * request = new QNetworkRequest(QUrl("http://mys...

does C++ allow to initialize struct using initializer list, {}, if struct has a defined constructor? could not find an answer, but g++ does not seem to allow it. struct r { int a; }; struct s { int a; s() : a(0) {} }; r = { 1 }; // works s = { 1 }; // does not work ...
Do I need a mutex if I have only one reader and one writer? The reader takes the next command (food.front()) from the queue and executes a task based on the command. After the command is executed, it pops off the command. The writer to the queue pushes commands onto the queue (food.push()). Do I need a mutex? My reader (consumer) only e...
I have a design question. Is it better to define separate classes for SENDING and RECEIVING. Or, is it better to define a single Thread class? I like the idea of a single Thread class because it is easier to share a queue which can be locked by mutex. Design Option #1 (Separate): mySendThread = new SendThread(); // Have thread properti...
Hi, I'm wondering if anyone has any ideas as to how I can host the Silverlight ActiveX control in an MFC application. I have been able to find information on this online, but everything that I have found is related to ATL or C# and so far I have been unable to translate any of this into my MFC application: Silverlight Alternative Hosti...
I was looking for solving a LCS problem (Longest common subsequence) and I tried to make my own code in c++ by referring to the explanation and the pascal code given at wikipedia. My final result was this: #include <iostream> #include <algorithm> using namespace std; int LCS(int a[100], int b[100], int m, int n); int main() { int ...
Hi, I have a problem where I get an int as input at the wrong time in my c++ program, so I need to "put it back" on cin later. However the closest thing I can find to do this is the pushback function for istreams. This sadly is only for characters and using multiple characters seems to separate them. Is there a good way to put a piece...
I just came across this post and found a very elegant way of initializing maps http://stackoverflow.com/questions/138600/initializing-a-static-stdmapint-int-in-c/1730798#1730798 So i wanted to start a thread in which we can list such idioms. They surely make you appreciate the power and expressiveness of C++ ...
Hello C++ Gurus, I have been using stl vector a lot, and recently I asked this question to myself,,, "How is stl vector implemented" I had two options:- 1) Linked list:- and then making the api to feel like random access (overloading []) 2) using new for e.g. DATA *temp = new DATA[20]:- I believe they do sth like this but then ...
