i using boost::ptr_vector < class > , use store objects of class b : public class a. want able access class b objects in vector; how cast access? ideally, a should provide virtual interface allows access parts of b need. if need access actual b objects, need use dynamic_cast on reference yielded iterator container (you use static_cast if knew certainty iterator pointed @ b object): // create container , insert new element it: boost::ptr_vector<a> s; s.push_back(new b()); // reference element inserted: b& b_ref = dynamic_cast<b&>(*s.begin()); if wanted iterate on b elements in container (and skip on non- b elements), using combination of boost's transform_iterator (to convert each a& b& ) , filter_iterator (to skip on non- b elements in container).

i'm working on function takes filepaths , dices them smaller sections. for example, if input parameter "cd mypath/mystuff/stack/overflow/string", want able return "cd" "mypath", "mystuff", "stack", "overflow", , "string" in succession. while continually use "getchar", appending results ever-increasing string, stopping when getchar returns '/', feel there must more elegant way achieve same functionality. any ideas? you can use char * strtok ( char * str, const char * delimiters ); using / separator. an example here: http://www.cplusplus.com/reference/clibrary/cstring/strtok/ #include <stdio.h> #include <stdlib.h> #include <string.h> int main(int argc, char* argv[]) { if (argc != 2) { fprintf(stderr, "usage: %s path\n", argv[0]); exit(exit_failure); } char* saveptr = null; (char* str = argv[1]; ; str = null) { char *token ...

Two Flash questions -

what _level0,_parent , _root mean in flash? what's difference between absolute path , relative path? levels in flash base root element of everything. every level has associated _root element, base of attached movieclips, whether on stages or dynamically loaded. _parent previous element along element hierarchy. example, if _root has movie clip n loaded it, n._parent == _root . absolute path , relative paths mean exact same thing in os. relative path relative initial container clip. absolute path absolute os.
