Hi, I've got a bunch of strings like: "Hello, here's a test colon:. Here's a test semi-colon;" I would like to replace that with "Hello, here's a test colon:. Here's a test semi-colon;" And so on for all printable ASCII values. At present I'm using boost::regex_search to match &#(\d+);, building up a string as I process e...
I'm writing a C++ static library that needs to be shared among several applications, one of them written in Perl. Unfortunately, I only barely know the core Perl language (I read the Llama book), and I'm not all that familiar with its libraries. How do you make calls to an external C++ binary from a Perl script? By Google search, I fo...
EDIT: This issue has been fixed by google in gtest 1.4.0; see the original bug report for more information. I've recently switched to gtest for my C++ testing framework, and one great feature of it which I am presently unable to use is the ability to generate JUnit-style XML test reports, which could then be read in by our hudson build ...
In ANSI C++, how can I assign the cout stream to a variable name? What I want to do is, if the user has specified an output file name, I send output there, otherwise, send it to the screen. So something like: ofstream outFile; if (outFileRequested) outFile.open("foo.txt", ios::out); else outFile = cout; // Will not compile bec...
I'm currently shopping for a FOSS parser generator for a project of mine. It has to support either C or C++. I've looked at bison/flex and at boost::spirit. I went from writing my own to spirit to bison to spirit to bison to spirit, each time hit by some feature I found unpleasant. The thing I hate most about bison/flex is that they a...
Yes, I do understand the difference between them. What I want to know is: why OVERRIDE a method? What is the good in doing it? In case of overload: the only advantage is you haven't to think in different names to functions? ...
Thank you guys so much for your help, this has been bothering me for a couple days. I am using Windows Vista, and writing my program in C++, using straight Windows API(no MFC). When I resize my window, the menu items flicker. My window class DOES NOT use CS_HREDRAW or CS_VREDRAW. I use double buffering for the CLIENT AREA, so the clien...
While porting a desktop application to windows mobile I've reached the following error: Error LNK2019: unresolved external symbol CompleteAuthToken referenced in function Reading MSDN it tell me that CompleteAuthToken is supported on Windows CE 2.10 and later and I should link against Secur32.lib, but adding that library didn't...
We're doing a great deal of floating-point to integer number conversions in our project. Basically, something like this for(int i = 0; i < HUGE_NUMBER; i++) int_array[i] = float_array[i]; The default C function which performs the conversion turns out to be quite time consuming. Is there any work around (maybe a hand tuned functi...
I have a question on C++ double dispatch. In the code below, I want the results from the second set to match the results from the first set. I don't know the actual type (unless I try dynamic_cast) but I do know that the object inherited from the BaseClass type. What is the most efficient (performance-wise) way to accomplish this? Aft...
I am trying to figure out how C and C++ store large objects on the stack. Usually, the stack is the size of an integer, so I don't understand how larger objects are stored there. Do they simply take up multiple stack "slots"? ...
I have stumbled in this phrase in the web: "C# is probably not the best choice for a system-level application like this. I believe plain C++ is much better here as you will need to do lots of low-level API calls." I was searching about security programs made using c#, like firewal, parental control, anti-virus, anti-spyware, etc. So, ...
Anyone have a link to what the C++ standard says regarding a compiler removing global and static symbols? I thought you weren't guaranteed that the compiler will remove global symbols if they're not referenced. A colleague of mine asserts that if your global symbols are included in the main translation unit, those symbols will not be re...
I would like to detect whether the OS I'm compiling on is Windows. Is there a simple macro I can check to verify that? ...
Suppose I have this in C++: void test(int &i, int &j) { ++i; ++j; } The values are altered inside the function and then used outside. How could I write a code that does the same in Java? I imagine I could return a class that encapsulates both values, but that seems really cumbersome. ...
In a visual studio C++ project, would MFC be faster than using the CLR? I'd specificily be using 2008. Oh and the reason I ask is because I have experience with .NET but not so much with MFC. I understand what MFC is but have never really used it much. ...
I need a smart pointer for my project which can be send to several methods as parameter. I have checked *auto_ptr* and *shared_ptr* from boost. But IMO, that is not suitable for my requirements. Following are my findings auto_ptr : When passed to another method, ownership will be transferred and underlying pointer will get deleted when ...
Hi, Using POSIX threads & C++, I have an "Insert operation" which can only be done safely one at a time. If I have multiple threads waiting to insert using pthread_join then spawning a new thread when it finishes. Will they all receive the "thread complete" signal at once and spawn multiple inserts or is it safe to assume that the thr...
