I have a destructor that performs some necessary cleanup (it kills processes). It needs to run even when SIGINT is sent to the program. My code currently looks like: typedef boost::shared_ptr<PidManager> PidManagerPtr void PidManager::handler(int sig) { std::cout << "Caught SIGINT\n"; instance_.~PidManagerPtr(); //PidManager is a...
Is there a C++ cross-platform library that provides me with a portable maximum integer number? I want to declare: const int MAX_NUM = /* call some library here */; I use MSVC 2008 unmanaged. ...
I guess this is very basic but since I'm learning .NET by myself, I have to ask this question. I'm used to coding in C, where you have to free() everything. In C++/.NET, I have read about the garbage collector. From what I understand, when an instance is no longer used (in the scope of the object), it is freed by the garbage collector. ...
I have an array of arrays that I want to pass into a DLL. I am running into the error "There is no marshaling support for nested arrays." I can pass a single array in fine but if I stack them up it fails. I need/want a "safe" way of passing in the array of arrays. private static extern int PrintStuff(string[][] someStringsInGroups, int...
I'm writing a C++ program that has a large number of classes. In my head I can visualise them as distinct collections. For example there's a collection of classes for reading and storing config data, and another collection for drawing a user interface with various widgets. Each of those collections could be neatly stored inside separate...
Ok, the context is some serialization / deserialization code that will parse a byte stream into an 'object' representation that's easier to work with (and vice-versa). Here's a simplified example with a base message class and then depending on a 'type' header, some more data/function are present and we must choose the right subclass to ...
I am trying to install a Levenshtein UDF for MySQL but I am having a ton of problems, I think mainly because of the lack of documentation for Macs. The specific UDF I am using is this one: http://joshdrew.com/mysql%5Flevenshtein%5Fudf-1.0.tar.gz and is done in C++. So far, I have gotten successful compilation using: g++ -Wall -bundle -...
I am trying to use the Microsoft Hierarchical FlexGrid (MSHFlexGrid) in a Visual C++ (VS 2005). I have the grid shown, and I can manually add data to the individual cells. However, according to online documentation I've read, I should be able to show the hierarchical nature of the data (hence MSHFlexGrid instead of MSFlexGrid) by defin...
I have a C++ class running in its own thread that needs to execute some javascript in a WebView that's part of a Cocoa app. I have the C++ app call a method in the Cocoa window's controller and it in turns runs the javascript, passing in the data. It seems to work part of the time, but crash a lot of the time as well (somewhere in WebVie...
Hi- I am trying to build a small program and I have my own library libfoo. I have a camera class that is calling a static function from my Vector3 class (i.e. crossProduct). My camera class and Vector3 class compile ok and are built into libfoo. However when I am linking like so: g++ -g -O2 -o test1 main.o -lfoo I get this: libfo...
I looked at Code::Blocks and it certainly looks great for c++ development, I like it's multiplatform capabilities (runs everywhere), but I wanted to get your feedback. Is it good/stable enough to be used in a professional environment? Thanks. ...
Hi, I am trying to build/run an old C++ system. I've already been able to built it in Ubuntu 9.10 with g++4.4 Now I'm trying to build in Ubuntu 8.04 with g++4.2. And I am getting the following errors: stringmap.h:353: erro: ISO C++ forbids declaration of ‘iterator’ with no type stringmap.h:353: erro: extra qualification ‘stringmap<_Tp>...
I want to view all traffic going out the USB, with the potential to block data transactions to/from the USB based on content policy. How would this be done? Any way to achieve this in C#, or is it more of a C++ type of problem? ...
I just downloaded the STL source code and I noticed all the definition for the STL template classes are included in the .h file. The actual source code for the function definition is in the .h file rather than .cpp/.c file. What is the reason for this? http://www.sgi.com/tech/stl/download.html ...
I would like to be able to convert between std::vector and its underlying C array int* without explicitly copying the data. Does std::vector provide access to the underlying C array? I am looking for something like this vector<int> v (4,100) int* pv = v.c_array(); EDIT: Also, is it possible to do the converse, i.e. how would I ini...
Hello, Im trying to build an array based, "Binary Search Tree" by following the algorithm at: http://highered.mcgraw-hill.com/olcweb/cgi/pluginpop.cgi?it=gif%3A:600%3A:388%3A%3A/sites/dl/free/0070131511/25327/tree%5Finsert.gif%3A%3ATREE-INSERT. ...using the algorithm I came up with the following code: void BST::insert( const data &aD...
I am trying to develop an IThumbnailProvider for use in Windows 7. Since this particular thumbnail would also be dependant on some other files in the same directory, I need to use something other than IInitializeWithStream to a path to work with, this being IInitializeWithItem. (Alternatively, I could use IInitializeWithFile, but that is...
Where can I get a sample code for merge sort a link list? ...
The classical unit testing is basically just putting x in and expecting y out, and automating that process. So it's good for testing anything that doesn't involve time. But then, most of the nontrivial bugs I've come across have had something to do with timing. Threads corrupt each others' data, or cause deadlocks. Nondeterministic behav...
Hello, So I have what is essentially a game... There is terrain in this game. I'd like to be able to create a top-down view minimap so that the "player" can see where they are going. I'm doing some shading etc on the terrain so I'd like that to show up in the minimap as well. It seems like I just need to create a second camera and s...
