When I call an unmanaged C++ code from my C# code, I seem to have some kind of a memory leak. The C++ reads data from a file using ifstream.read, and writes it to a Vector. This happens only after upgrading to Windows 7, doesn't happen on Vista, but if I use a version of the native dll that was compiled on Vista, it doesn't change anyth...
I'm looking for a way to reliably determine whether C++ code is being compiled in 32 vs 64 bit. We've come up with what we think is a reasonable solution using macros, but was curious to know if people could think of cases where this might fail or if there is a better way to do this. Please note we are trying to do this in a cross-platfo...
Hi! I need to get the result from pow(a,b) as an integer (both a and b are integers too). currently the calculations where (int) pow( (double)a, (double)b) is included are wrong. Maybe someone can help with a function that does the pow(a,b) with integers and returns an integer too? But here is the odd part: I made my script in Linux wi...
Hi! I have an IP address in char type Like char ip = "192.123.34.134" I want increment the last value (134). Does anyone how should i do it? I think, i should convert it to an integer, and then back, but unfortunately i don't know how? :( I'm using C++. Please help me! Thanks, kampi ...

I'm learning c++ and writing a binary search tree. The following is the code I wrote for my insert method. BSTNode * BST::Insert(const std::string & v) { BSTNode *n = !root ? root = new BSTNode(v) : Insert_Helper(v,root); if(n) size++; return n; } BSTNode * BST::Insert_Helper(const std::string & v, BSTNode *n) { if(!n->value.compar...
In java debugging a hung application is easy. You can take the memory dump of the application and use and use eclipse jvm dump analyser to see the status of the threads and where each threads were blocked? Does something like this exists for C++? ...
Hi all do you guys know of any programs which can be used to visualize error messages from gcc. I am imagining something which will allow interactively to collapse all those long template typenames, color code different parts of the error message and what not. ...

I have a class whose name is YourClass. And my problem is WHY compiler do NOT generate an error for following code? YourClass AMethod(){ return YourClass();} AMethod() = YourClass(); [In this case IN MY OPINION AMethod just return a value (I mean it do not have a l-value).] EDIT: If I can do that above why I can not do following int...
I am going to try to ask this question without supplying too much source code because all the relevant bits add up to a bunch. The key (I think?) objects involved are using namespace o2scl; typedef MSMTModel<TASensor,PosModel,target2d,ovector,ovector_const_subvector> TA_MSMTModel; typedef MPC_funct_mfptr<MSMT_InitialState,TA_MSMTModel...
I have two pointers to objects and I want to test if they are the exact same object in the most robust manner. I explicitly do not want to invoke any operator == overloads and I want it to work no matter what base classes, virtual base classes and multiple inheritance is used. My current code is this: ((void*)a) == ((void*)b) And for...
Apologies if I'm missing something really obvious, but I'm trying to understand how to write a custom front end and back end with Pantheios. (I'm using it from C++, not C.) I can follow the purposes of the initialisation functions (I think) but I'm unsure about the others: pantheios_be_logEntry, pantheios_fe_getProcessIdentity and panth...
