How to search folders for files?
Author
Hail fellow programmers, I wrote a programming tool that opens a spefic file and changes all instances of one word with another word. It''s really useful when I wish to change an obscure variable name or change the style of my programming. Its works great but I must manually enter in the file name each time I want the program to edit a file. How can I arrange it so I can get my program to go search through a directory and its subdirectors and use its word exchange functions on, lets say all *.h, and and all *cpp. files in a named directory. I''m using msdev 6.0 and programming in c++. I''ve searched the forums for related topics, but to avail. I''m looking for an answer that uses some l337 c++ stream/file hack , or just the right win32 api call. Please no mfc! Thanks in advance

You can do this with FindFirstFile and FindNextFile. Here''s an example of how to list all files matching a given string (such as "c:\\something\\*.txt").
std::vector<std::string> findFiles(const std::string& match){ WIN32_FIND_DATA fileData; HANDLE hFind; std::vector<std::string> result; hFind = FindFirstFile(match.c_str(),&fileData); if(hFind != INVALID_HANDLE_VALUE) { do { if((fileData.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY) == 0) result.push_back(fileData.cFileName); } while(FindNextFile(hFind,&fileData)); FindClose(hFind); } return result;}

Thanks Beer Hunter By the way, are you using the STL in your example? I''m not familier with std::vector(..).

actually if your using msdev, you can just hit ctrl-shif-h to file and replace in all your project files. or sctrl-shift-f to search throught them.
the key mappings might be diffrent from vc.net but its all there. check it!

quote:Original post by xorjesusYes, it''s from the STL. std::vector represents a dynamic array (in this case, of strings). The push_back function increases the size by 1 and puts the given item (the filename) at the end. To read items from it, you''d do something like:

std::vector<std::string> files = findFiles("data\\*.txt");for (int i = 0; i != files.size(); ++i){ std::cout << files[i] << std::endl;}// ORfor (std::vector<std::string>::const_iterator i = files.begin(); i != files.end(); ++i){ std::cout << *i << std::endl;}This topic is closed to new replies.
