Thread: Recursive search error

Hi. I'm trying to search all drives for files and have such code:

Code:

int main()
{
TCHAR szCurrDrive[] = L"C:\\";
  TCHAR szPath[MAX_PATH+1];
  DWORD i, dwDisksMask = GetLogicalDrives();

  for(i = 0; i < 26; i++) {
    if(dwDisksMask & 1) {
      lstrcpy(szPath, szCurrDrive);
      RecursiveSearch(szPath);
    }
    dwDisksMask >>= 1;
    szCurrDrive[0]++;
  }

/////

Code:

VOID RecursiveSearch(LPWSTR szPath) {
  WIN32_FIND_DATA fdFindData;
  HANDLE hFind;
  
  PCWSTR ext1 = L".xls";
  PCWSTR ext2 = L".xlsx";
  TCHAR * CONST lpLastChar = szPath + lstrlen(szPath);

  lstrcat(szPath, L"*");
  hFind = FindFirstFile(szPath, &fdFindData);
  
  if(INVALID_HANDLE_VALUE == hFind) {
      DWORD lastError = GetLastError();
      std::cout << lastError;

      system("pause");
    return;
  }

  do {
      if ((0 == lstrcmp((LPCWSTR)fdFindData.cFileName, L".")) ||
          (0 == lstrcmp((LPCWSTR)fdFindData.cFileName, L".."))) {
      continue;
    }
      lstrcat(szPath, (LPCWSTR)fdFindData.cFileName);
    if(fdFindData.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY) {
      lstrcat(szPath, L"\\");
      RecursiveSearch(szPath);
    } else {
        if (NULL != StrStr((LPCWSTR)fdFindData.cFileName, ext1) || StrStr((LPCWSTR)fdFindData.cFileName, ext2)
        
      {
        std::wcout<<fdFindData.cFileName<<std::endl;
        FoundFile(fdFindData.cFileName);
        
      }
    }
    
  } while(FindNextFile(hFind, &fdFindData));

  FindClose(hFind);
}

But receive ERROR_INVALID_NAME error. Where's the problem?
