c++ - find files in whole hard disk -


this question has answer here:

i have program searches files of particular extension in specific drive (i using windows), let it's "c:\" , print these files on console. want generalize program. want program search in partitions (drives) .. how can this.. function should use..here code sample

int searchdirectory(std::vector<std::string> &refvecfiles,                 const std::string        &refcstrrootdirectory,                 const std::string        &refcstrextension,                 bool                     bsearchsubdirectories = true) {   std::string     strfilepath;             // filepath   std::string     strpattern;              // pattern   std::string     strextension;            // extension   handle          hfile;                   // handle file   win32_find_data fileinformation;         // file information    strpattern = refcstrrootdirectory + "\\*.*";    hfile = ::findfirstfile(strpattern.c_str(), &fileinformation);   if(hfile != invalid_handle_value)   {         {       if(fileinformation.cfilename[0] != '.')       {         strfilepath.erase();     strfilepath = refcstrrootdirectory + "\\" + fileinformation.cfilename;      if(fileinformation.dwfileattributes & file_attribute_directory)     {       if(bsearchsubdirectories)       {         // search subdirectory         int irc = searchdirectory(refvecfiles,                                   strfilepath,                                   refcstrextension,                                   bsearchsubdirectories);         if(irc)           return irc;       }     }     else     {       // check extension       strextension = fileinformation.cfilename;       strextension = strextension.substr(strextension.rfind(".") + 1);        if(strextension == refcstrextension)       {         // save filename         refvecfiles.push_back(strfilepath);       }     }   } } while(::findnextfile(hfile, &fileinformation) == true);  // close handle ::findclose(hfile);  dword dwerror = ::getlasterror(); if(dwerror != error_no_more_files)   return dwerror;   }    return 0; }    int main() {       int                      irc         = 0;   std::vector<std::string> vecavifiles;   std::vector<std::string> vectxtfiles;     // search 'c:' '.avi' files including subdirectories    irc = searchdirectory(vecavifiles, "c:", "apk");   if(irc)  {     std::cout << "error " << irc << std::endl;    return -1;   }    // print results   for(std::vector<std::string>::iterator iteravi = vecavifiles.begin();   iteravi != vecavifiles.end();   ++iteravi) std::cout << *iteravi << std::endl;    // search 'c:\textfiles' '.txt' files excluding subdirectories   irc = searchdirectory(vectxtfiles, "c:", "txt", false);   if(irc)  {      std::cout << "error " << irc << std::endl;     return -1;  }   // print results   for(std::vector<std::string>::iterator itertxt = vectxtfiles.begin();     itertxt != vectxtfiles.end();      ++itertxt)      std::cout << *itertxt << std::endl;     // wait keystroke  _getch();   return 0; }

i'm no windows programmer looks have find out drives available in system , call function of them. see here how list of available drives on windows: enumerating available drive letters in windows

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
