Hello. The problem is as follows. Wrote applications one of the functions of which is a recursive directory traversal. When this application is launched on another computer with another language installed, it crashes with the message PROGRAM CRASH. Through a long search, I found that the problem lies in the names of files and folders containing Chinese characters. When the program reaches them, it crashes with the above error. How to add support for different languages ​​to a Visual Studio project? Tell me please. Already day I suffer with this.

WIN32_FIND_DATAW ffd; TCHAR szDir[MAX_PATH]; size_t length_of_arg; HANDLE hFind = INVALID_HANDLE_VALUE; DWORD dwError = 0; StringCchLength(dir, MAX_PATH, &length_of_arg); StringCchCopy(szDir, MAX_PATH, dir); StringCchCat(szDir, MAX_PATH, TEXT("\\*")); hFind = FindFirstFile(szDir, &ffd); if (INVALID_HANDLE_VALUE == hFind) { return 0; } do { try { if (ffd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY) { if (!(std::wstring(L".") == std::wstring(ffd.cFileName)) && !(std::wstring(L"..") == std::wstring(ffd.cFileName)))) { try { TCHAR directory[MAX_PATH]; StringCchCopy(directory, MAX_PATH, dir); StringCchCat(directory, MAX_PATH, TEXT("\\")); StringCchCat(directory, MAX_PATH, ffd.cFileName); //wprintf(L"%s: %s\n", L"Folder", directory); get_paths_arguments((STRSAFE_LPWSTR)directory, ctls, len); } catch (exception &ex) { std::cout << "EXCEPTION ON GET DIR NAME"; } } } else { if (ffd.cFileName != NULL) { TCHAR directory[MAX_PATH]; StringCchCopy(directory, MAX_PATH, dir); StringCchCat(directory, MAX_PATH, TEXT("\\")); StringCchCat(directory, MAX_PATH, ffd.cFileName); //wprintf(L"%s: %s\n", L"File", directory); ctls->catls[*len].name = (STRSAFE_LPWSTR)directory; *len = *len + 1; ctls->length = *len; //cout << hFind << endl; if (*len == (ctls->size - 1)) { std::cout << "CRITICAL SIZE OF PATHS STRUCTURE" << std::endl; FindClose(hFind); return 0; } } } } catch (char * str) { cout << "EXCEPTION ON GET_PATHS_ARGUMENTS: " << *str << endl; return 0; } } while (FindNextFile(hFind, &ffd)); FindClose(hFind); return 0;
  • Not enough in the question of your code, because I think the problem is not the lack of support for different languages, as it seemed to you - gil9red
  • Corrected. Completely all function code. There in the code were my pitiful attempts to catch exceptions. - Andrey Bespalov

Understood. The problem was that the return value of the StringCchCopy and StringCchCat functions was not checked. After I received the return value and compared it with S_OK, everything became good. The problem was apparently exceeding the maximum path length.
