Hello, I want to know if it is possible to end a for loop in C++ when an ending condition (different from the reacheing right number of iterations) is verified. For instance: for (int i = 0; i < maxi; ++i) for (int j = 0; j < maxj; ++j) // But if i == 4 < maxi AND j == 3 < maxj, // then jump out of the two nested lo...
What is the difference between the three functions and when to use them?? ...
I have an ISAPI extension DLL written in C++ using Microsoft Visual Studio 2003 running in IIS 5.1 on XP Pro. Whenever an _ASSERTE fires I just get a an empty message box with 'Error' in the title bar and Abort/Retry/Ignore buttons. What I don't see is any of the expression text from the _ASSERTE macro. I've traced into the runtime libra...
I am not familiar with this, and can use a kick start. I am using ATL (unmanaged C++) user control and would like to use the ShockWave ActiveX object. I need to know how to declare it so that I can set a property or call a method. For instance, if I could assign a variable to it, then I would like to call 'variable->LoadMovie()' I kno...
Lately all modern programming languages have a definitive web site to support, distribute, learn the programming language, as well as community forums, e-mail lists and so on. Java has java.sun.com, python has python.org, etc. However C/C++ does not seem to have such a site. Which site do you use, say in a document, to link for C or C+...
I just got handed an SDK made of C++ dll, lib, exe, and various .h files. I presume it is meant for C++ developers. The sample projects they provide with their documentation are all written in C++. I am able to spin them up with Visual Studio 8 (2005) and run them. They do control the device as advertised. However the project this nee...
Is there a way to make all character sequences UNICODE by default? For instance, now I have to say: std::wstring wstr(L"rofl"); instead, I'd like to say std::wstring wstr("rofl"); Thanks! Visual C++ 8.0 ...
I am storing objects in a buffer. Now I know that I cannot make assumptions about the memory layout of the object. If I know the overall size of the object, is it acceptible to create a pointer to this memory and call functions on it? e.g. say I have the following class: [int,int,int,int,char,padding*3bytes,unsigned short int*] 1) ...
I'm programming C++ with normal pointers, but I have heard about libraries like Boost that implement smart pointers and I have seen that in Ogre3D rendering engine there is a deep use of shared pointers. What's exactly the difference between the three, and should I stick on using just a type of them? Thanks. ...
Hi! Is there a pythonic way of reading - say - mixed integer and char input without reading the whole input at once and without worrying about linebreaks? For example I have a file with whitespace-separated data of which I only know that there are x integers, then y chars and then z more integers. I don't want to assume anything about l...
I'm examining the feasibility of porting an existing Windows MFC control to OS X/Carbon. My test bed is a C++ Carbon application generated using the XCode 3 Wizard. I'm looking for a quick way to dump some trace info to the debugger or the OS X equivalent of DbgView. On Win32 I'd use OutputDebugString() - what's the deal on OS X? Is th...
I tried to compile the example posted (http://stackoverflow.com/questions/412165/c-service-providers) and failed to VS8 VC9. I have little experience with template. Any suggestions? Tanks. These are the errors : dictionarystl.cpp(40) : error C2663: 'std::_Tree<_Traits>::find' : 2 overloads have no legal conversion for 'this' pointer dic...
I don't know why this is question is bugging me, but time after time I come back to the though - why not make websites in C++? So far I know of none (except a rumor about Yahoo). Most use PHP, Java or ASP.NET. Some are built on Ruby or Python, but even those are minorities. At the same time, looking at StackOverflow, it seems that C++ i...
InternalsVisibleTo is not working for my managed C++ projects, but it is for my C# projects. Any help would be appreciated. Here is a simplified layout. Project A - C#, has an internal property I want to access from B/C. Project B - Managed C++. References A. Project C - C#, references A. All projects are signed with the same key. Lo...
EDIT: I suppose I should clarify, in case it matters. I am on a AIX Unix box, so I am using VAC compilers - no gnu compilers. End edit I am pretty rusty in C/C++, so forgive me if this is a simple question. I would like to take common functions out of a few of my C programs and put them in shared libraries or shared objects. If I w...
I need to find out the CPU utilization of a service DLL. I have looked in existing samples and we can find CPU utilization for processes. I think DLL will be loaded by services.exe. So is it possible to find out CPU utilization by DLL. I am working in C++ on the Windows platform. ...
#include "iostream" #include "vector" class ABC { private: bool m_b; public: ABC() : m_b(false) {} ABC& setBool(bool b) { m_b = b; return *this; } bool getBool() const { return m_b; } }; void foo(const std::vector<ABC> &vec) { vec[0].setBool(true); } ...
I'm in need of a C++ (pseudo, i don't care) random number generator that can get me different numbers every time I call the function. This could be simply the way I seed it, maybe there's a better method, but every random generator I've got doesn't generate a new number every time it's called. I've got a need to get several random number...
Apart from method calls not being optimized, are there any other issues? A difference I have noticed is that default compiler generated methods (e.g. operator=) in the class appear either in the exporting dll (if dllimport is used by the client) or in the client binary (if dllimport is not used). In this latter case, it's almost as if ...
I have a pointer to pointer array. I am assigning each row in the while loop below and the printf inside the while loop shows each is assigned my id number 1-20. After, out side of the while loop I iterate through the array and every element is written with id 20? Any help is greatly appreciated. (FYI- I am using the Template2doc library...
