c++ - Destructor vs member function race again -

-
i've seen similar question: destructor vs member function race .. didn't find answer following. suppose have class owning worker thread. destructor of class can like: ~ourclass { ask_the_thread_to_terminate; wait_for_the_thread_to_terminate; .... do_other_things; } the question is: may call ourclass's member functions in worker thread sure these calls done before do_other_things in destructor? yes can. destruction of member variables willonly start after do_other_things completes execution. safe call member functions before object gets destructed.

this question has answer here: formatting doubles output in c# 10 answers storing double 2 digit precision 4 answers i don't know how remove tail of 0 on "double" conversion generic currency string in c#. this code double reddito = math.round(convert.todouble("12500,245"), 3); the expected result reddito = 12500.245 the real result reddito = 12500.245000000001 what matter? for currencies best use decimal type rather double. doubles , floats approximations of real number , can trouble financial calculations. recommended practice not test floats , doubles equality allow small tolerance around value particular reason.

C++: convert TCHAR array to std::string -

-
i want convert tchar array std::string . after searching internet, did way: tchar filename[260]; getprocessname( reinterpret_cast<dword>(processid), filename, max_path ); std::wstring tmpwstring( filename ); std::string result( tmpwstring.begin(), tmpwstring.end() ); std::cout << "the length of tmpwstring is: " << tmpwstring.length() << std::endl; this gives me tmpwstring of length 0 . however, pure coincidence, added sleep function before conversion, goes smoothly, , can conversion result properly: tchar filename[260]; ::sleep(500); getprocessname( reinterpret_cast<dword>(processid), filename, max_path ); std::wstring tmpwstring( filename ); std::string result( tmpwstring.begin(), tmpwstring.end() ); std::cout << "the length of tmpwstring is: " << tmpwstring.length() << std::endl; std::cout << "this resulted string: " << result << std::endl;
