c++ - Weird characters in a std::vector<TCHAR*> -

trying sub directories, , files in sub directories, , i'm passing std::vector reference function gets of directories. can cout cfilename inside function once returns main vector has weird characters.

currently have character set use unicode. when using multibyte print weird characters, prints nothing. vector have in (directories.size() returns value > 0)

can't think of else. question lol. thanks

in listdirectories() function

tchar subdir[max_path]; ... directories.push_back(subdir); 

subdir array local do ... while loop within function , lifetime ends every iteration of loop.

change std::vector<tchar*> directories; std::vector<std::basic_string<tchar>> directories; , code should work correctly. you'll make copy of directory name , add vector.

another alternative forget tchar stuff , use wide character versions of when dealing windows api.

std::vector<std::wstring> directories; wchar_t cdirectory[max_path]; ... hfind = findfirstfilew(buffer, &data);
