DOC: FindNextFile Returns 0 for Last File Found

• The Microsoft Foundation Classes (MFC), included with:
  • Microsoft Visual C++, 32-bit Editions, versions 4.2, 5.0, 6.0

SUMMARY

The documentation for CFileFind::FindNextFile, CFtpFileFind::FindNextFile, and CGopherFileFind::FindNextFile in the Class Library Reference with Visual C++ is incorrect. The documentation states:

   Return Value

   Nonzero if successful; otherwise 0. To get extended error information,
   call the Win32 function GetLastError. 

   Return Value

   Nonzero if there are more files; zero if the file found is the last one
   in the directory or if an error occurred. To get extended error
   information, call the Win32 function GetLastError. If the file found
   is the last file in the directory, or if no matching files can be found,
   the GetLastError function returns ERROR_NO_MORE_FILES. 

MORE INFORMATION

The code below shows how to use CFileFind::FindNextFile to find every file in a directory.

Sample Code

   CFileFind finder;
   BOOL bWorking = finder.FindFile("*.*");
   while (bWorking)
   {
       bWorking = finder.FindNextFile();
       // Do processing here
   }
