I'm trying to teach myself C++, and one of the traditional "new language" exercises I've always used is to implement some data structure, like a binary tree or a linked list. In Java, this was relatively simple: I could define some class Node that maintained an instance variable Object data, so that someone could store any kind of object...
Any recommendations for gratis (i.e. free as in free beer) profilers which can be integrated with Visual C++ 2005? I'm using Very Sleepy right now (which is really nice), but wouldn't mind shifting if there were a better option. ...
I have a few classes with a few named constructors. When I inherit from them, how should I inherit the constructors? The problem is that they return objects of base class and not of the child class. Side question: can I use C++0x "using" to reduce the amount of boilerplate code? ...
What is the difference between c++ dynamic binding and java dynamic binding? ...
Hi, I'm trying to write mocks using amop. I'm using Visual Studio 2008. I have this interface class: struct Interface { virtual void Activate() = 0; }; and this other class which receives pointers to this Interface, like this: struct UserOfInterface { void execute(Interface* iface) { iface->Activate(); } }; So I try...
Hi, I've got an IE BHO plugin that sends out via a COM call the HTML of a page that was loaded in the window. // Note all error handling removed for readability :) STDMETHODIMP CPlugin::get_HTML(long lMaxSize, BSTR *pbstrHTML) { CComPtr<IDispatch> pDispatch; MSHTML::IHTMLDocument2Ptr pDocument2 = NULL; MSHTML::IHTMLDocument3Ptr pDocu...
I'm a longtime Visual Studio(from versions 6 to 2008) user that really like the editor and especially the debugger. Now I'm thinking of giving Linux a go, is there a IDE with similar, or better, capabilities out there? I'm also interested in recommendations for GUI libraries, c++ or c#. ...
How do I maximize the CPU usage for my application? I tried setting it to "Real-time" in the Task Manager, but there was no noticeable improvement - it's stuck at 50%. I'm working in Windows XP with Visual C++ 2005. ...
I am building a 32-bit C++ COM project on a 64-bit version of Windows 7. The #import looks something like: #import "C:\Program Files\Common Files\Microsoft Shared\CAPICOM\CapiCom.dll" The problem is, on x64, that directory doesn't work. If I change the path to C:\Program Files (x86)..., then the build works. But now it won't build on 3...
I'm looking for a library that could be used to manipulate audio files. Essentially what I would like to do is: Load an MP3/WAV file Get a 15 second clip of the file Overlay another MP3/WAV file ontop of it Render as a new MP3/WAV file ...
I'm porting over some code from one project to another within my company and I encountered a generic "sets_intersect" function that won't compile: template<typename _InputIter1, typename _InputIter2, typename _Compare> bool sets_intersect(_InputIter1 __first1, _InputIter1 __last1, _InputIter2 __first2, _InputIter2 __...
Why or how does the file __init__.py cause the python interpreter to search subdirectories for a module -- and why does the interpreter not honor this convention when invoked from C++? Here's what I know: Using strace on my program, I can see that the same python2.5 interpreter is being executed for both the interactive case and the ...
Can I use default arguments in a constructor like this maybe Soldier(int entyID, int hlth = 100, int exp = 10, string nme) : entityID(entyID = globalID++), health(hlth), experience(exp), name(nme = SelectRandomName(exp)) { } I want for example exp = 10 by default but be able to override this value if I supply it in the constructor othe...
Hi, I'm comparing the following code in C++ and C# and C# (Mono 2.4) seems to be faster. Is there anything wrong with the C++ code? #include <map> #include <string> #include <iostream> #include <ext/hash_map> #include <boost/any.hpp> int main() { //std::map<long, long> m; // hash_map is a little bit faster __gnu_cxx...
Hello, My friend have real Macintosh IIci, that uses Mac System 7.5.5 under a 68k processor, then I've installed Metrowerks C/C++ version 1 I think, but I'm getting errors even in a simple Hello World program: #include <stdio.h> int main(void) { printf("Hello, World!"); return 0; } I'm getting this error: ·· Link Error : Li...
All, I am trying to find a similar function to 'strstr' that searches a substring starting from the end towards the beginning of the string. Thanks ...
Hi! I wrote a little program, which is working like a ping command(i use ICMPSendEcho2), but it gives back a return value, not only a text message. Now I have only one question. How can I programmatically check if a hostname exist or not? I mean if i want to ping computerA, and i don't even have a computerA then it should say what the o...
I have a question regarding "best-practice" when including headers. Obviously include guards protect us from having multiple includes in a header or source file, so my question is whether you find it beneficial to #include all of the needed headers in a header or source file, even if one of the headers included already contains one of t...
Hello, I've ran into a problem when CreateInterfaceIterator does not return all interfaces for the device. When I open "USB Prober" it says there are 9 interfaces, but displays 14 of then counting Interface #1 - Vendor-specific Interface #1 - Vendor-specific (#1) as one interface. The problem is that CreateInterfaceIte...
In section 11.5.1 of "The C++ Programming Language", Bjarne Stroustrup writes: Like a member declaration, a friend declaration does not introduce a name into an enclosing scope. For example: class Matrix { friend class Xform; friend Matrix invert (const Matrix &); //.. }; Xform x; // error: no Xform in scope Matrix (*p...
