i have program button, when clicked, executes sound located in download folder. question how execute sound on computer if path finding different. you need path file run it. if don't have path - have search it. pick base directory think file is. if don't know - whole drive. write recursive function search said folder recursively. test each file ever search condition is, i.e. file name, file hash, etc. for example: string searchforfile(string searchpath, func<string, bool> searchpredicate) { try { foreach (string filename in directory.enumeratefiles(searchpath)) { if (searchpredicate(filename)) { return filename; } } foreach (string dirname in directory.enumeratedirectories(searchpath)) { var childresult = searchforfile(dirname, searchpredicate); if (childresult != null) { return childresult; ...

i trying iterate through list , then, if object's plate number matches 1 given through parameters, , if toll (calculated in toll()) less or equal given cents, remove/erase object list. keep getting error list iterator cannot incremented , i'm clueless how fix it. void one_time_payment(string& plate_number, int cents) { // todo: rewrite function std::list<licensetrip>:: iterator it; (it = listlicense.begin(); != listlicense.end(); std::advance(it, 1)) { if (it->plate_number().compare(plate_number) == 0) { cout << "matching plate found" << endl; if (it->toll() <= cents) { cout << "can paid" << endl; = listlicense.erase(it); //error: list iterator cannot incremented } } } cout << "end of iterator" << endl; } this is, i'm guessing, not compile error rather assertion triggere...
