I'm trying to get a C++ service to load an XML document from a MSMQ message generated by C#. I can't really change the C++ side of things because I'm trying to inject test messages into the queue. The C++ service is using the following to load the XML. CComPtr<IXMLDOMDocument2> spDOM; CComPtr<IXMLDOMNode> spNode; CComBSTR bstrVal; ...
Hello Is there a way to enforce STL container alignment to specific byte, using attribute((aligned))perhaps? the target compilers are not Microsoft Visual C++. What libraries, if any, provide specialized templates of STL algorithms which have specific explicit vectorization, e.g. SSE. My compilers of interest are g++, Intel, and IBM X...

Okay, I am writing a program that is doing some pretty heavy analysis and I would like to be able to stop it quickly. I added signal(SIGINT, terminate); to the beginning of main and defined terminate like: void terminate(int param){ cout << endl << endl << "Exit [N]ow, or [A]fter this url?" << endl; std::string answer; cin >> ...
Hello. I am using OpenCV library and I want to clone picture in separate function, but I cannot send address to the function IplImage* image = cvLoadImage( path, CV_LOAD_IMAGE_GRAYSCALE ); // loading is ok showFoundPoints(image); // -> here it shows errors ... //my function int showFoundPoints(IplImage*image) {...} And I got t...

Hi, I have taken a graduate level course which is just one big project - to write a DBMS. The objective is not to reinvent the wheel and make an enterprise DBMS to rival Oracle. Only a small subset of SQL commands need to be supported. Nor is the objective to create some fancy hybrid model DBMS for storing multimedia or something. It ha...
I'd like to use boost::array as a class member, but I do not know the size at compile time. I thought of something like this, but it doesn't work: int main() { boost::array<int, 4> array = {{1,2,3,4}}; MyClass obj(array); } class MyClass { private: boost::array<int, std::size_t> array; public: template<s...
As described here http://www.ddj.com/cpp/184401688 I do not have time to write this from scratch. Asked and not answered http://stackoverflow.com/questions/434961/implementing-ssl THE QUESTION IS: I am looking for some compilable working source code that implements MS SSPI (as alluded to in the thread above), procedural not OOP prefe...

hello I am trying to get a better idea of performance of virtual functions here is an example code: struct Foo { virtual void function1(); virtual void function2() { function1(); } }; struct Bar : Foo { virtual void function1(); } Bar b; Foo b.function2(); b.function1(); f.function2(); for each of three calls in the...
I found in one article saying "static_cast is used for non-polymorphic type casting and dynamic_cast is used for polymorphic type casting". I understand that int and double are not polymorphic types. However, I also found that static_cast can be used between base class and derived class. What does polymorphic type here mean? Some peopl...
I have a SWIG C++ function that expects a function pointer (WNDPROC), and want to give it a Python function that has been wrapped by ctypes.WINFUNCTYPE. It seems to me that this should be compatible, but SWIG's type checking throws an exception because it doesn't know that the ctypes.WINFUNCTYPE type is acctually a WNDPROC. What can I ...
I don't understand why the ABI is important context of developing user-space applications. Is the set of system calls for an operating system considered an ABI? But if so then aren't all the complexities regarding system calls encapsulated within standard libraries? So then is ABI compatibility only relevant for running statically link...

When running the following code and enter a number, it works fine. But when entering a letter, the program enters an infinite loop, displaying "Enter a number (0 to exit): cin failed." My intent was to handle the cin fail case and prompt the user again. int number; do{ cout << "Enter a number (0 to exit): "; cin >> number; ...
In C++, is there any way to query the type of an object and then use that information to dynamically create a new object of the same type? For example, say I have a simple 3 class hierarchy: class Base class Foo : public Base class Bar : public Base Now suppose I give you an object cast as type Base -- which is in reality of type Foo...
I know that COM provides resuability at binary level across languages and applications. I came to know that all components build based on COM have standard memory layout inorder to be language indepedent. I am not getting what is the meaning of "standard memory layout"? And What makes it language independent ? Any input is welcomed......
I want a class which takes two parameters in its constructor. The first can be either an int, double or float, so , and the second is always a string literal "my string", so I guess const char * const. Can anyone give me some compilable code which declares a simple class template as described and declares an object of that class? Than...
