Files

You must use findfirst/findnext function.:

    struct ffblk  fileinfo;

    int done =!findfirst("*.*", &fileinfo, 0))
    while (!done)
        {
           .....
          done = findnext(&fileinfo);//next file
        }
 

Of couse 1-st line
 ine done = findfirst(..);

I don't know how to access the filename after to do that!

my code:

int done;
struct ffblk fileinfo;
done = !findfirst("*.*", &fileinfo, 0);

while (!done)
  done = findnext(&fileinfo);
 

I don't know how to access the filename after to do that!

my code:

int done;
struct ffblk fileinfo;
done = !findfirst("*.*", &fileinfo, 0);

while (!done)
  done = findnext(&fileinfo);

Win32 code to do this, say szDirectory is the directory you want to scan

char szCleanDir[MAX_PATH+10] ;
         char szSearchPath[MAX_PATH+5] ;
         WIN32_FIND_DATA fd ;
         HANDLE hh ;
         int ll ;
         BOOL bOK = TRUE ;

         /* Make sure dir has final slash */
         strcpy( szCleanDir, szDirectory ) ;
         ll = strlen(szCleanDir) ;
         assert( ll > 0 ) ;
         if ( szCleanDir[ll-1] != '\\' )
         {
         strcat( szCleanDir, "\\" ) ;
         }

         /* Generate search path */
         strcpy( szSearchPath, szCleanDir ) ;
         strcat( szSearchPath, "*.*" ) ;

         /* Do search */
         hh = FindFirstFile( szSearchPath, &fd ) ;
         while ( ( hh != NULL ) && ( bOK ) )
         {
         if ( ( fd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY ) != 0 )
         {
         /* it's a directory */
         char szSubDirectory[MAX_PATH+10] ;
         if ( strcmp( (char *)fd.cFileName, "." ) == 0 ) continue ;
         if ( strcmp( (char *)fd.cFileName, ".." ) == 0 ) continue ;
         strcpy( szSubDirectory, szCleanDir ) ;
         strcat( szSubDirectory, (char *)fd.cFileName ) ;
         printf( "Subdirectory '%s'\n", szSubDirectory ) ;
         } else
         {
         /* it's a file */
         printf( "File '%s'\n", (char *)fd.cFileName ) ;
         }

         bOK = FindNextFile( hh, &fd ) ;

         } /* while* /

         if ( hh != NULL ) FindClose(hh) ;

Sorry, man! I didn't explain. It's not for Win32, it's for DOS!

Okay - in VC.#include <io.h>

use _findfirst instead of FindFirstFile
use _findnext instead of FindNextFile
use _findclose instead of FindClose

change type of hh to a long
change tests on hh against NULL to tests against -1

change fd's type to struct _finddata_t

the filename is in the name member of this struct

attrib member of structure contains attributes of the found item (do bitwise tests)

e.g.
if ( ( fd.attrib & _A_SUBDIR ) != 0 ) { /* it's a sub dir */ }

    struct ffblk  fileinfo;

    int done =!findfirst("*.*", &fileinfo, 0))
    while (!done)
        {
          char *szFileName = fileinfo.ff_name;
          ..... you code
          done = findnext(&fileinfo);//next file
        }
 

how about something like this??

system("dir > Datafile.dat");

Merry Christmas!

lifeson , do you test my last comment? if it is OK, i can write
it as reply?
Happy new year!

A note about my solution and the findfirst/findnext functions.
The following are the 'modes' that can be passed to the findfirst function.  This is the file atrribute of the file.

#define FA_NORMAL   0x00        /* Normal file, no attributes */
#define FA_RDONLY   0x01        /* Read only attribute */
#define FA_HIDDEN   0x02        /* Hidden file */
#define FA_SYSTEM   0x04        /* System file */
#define FA_LABEL    0x08        /* Volume label */
#define FA_DIREC    0x10        /* Directory */
#define FA_ARCH     0x20        /* Archive */

Now, the code you have has the line:

done = findfirst("*.*",&ffblk,0);

The 0 in the above represents a 'normal' file.  To get a more complete listing of a directory's contents, you may want to mask the mode.
For example:

#define FA_LIST (FA_RDONLY|FA_HIDDEN|FA_SYSTEM|FA_DIREC|FA_ARCH)

Now, if you use FA_LIST like this:

done = findfirst("*.*",&ffblk,FA_LIST);

you will get a listing of everything in the directory, including sub-directories.  If you want to know what has been returned to the ffblk structure, check ffblk.ff_attrib and compare it with the #defines listed above.  If you don't want what is returned (maybe you are not interested in hidden files for example), you simply don't allocate a string to keep that listing.

Hope this helps.
