_rmdir

[willi808]

hi,

i must delete all files under dos (visual studio 1.5).
i use _rmdir but before deleting i must delete all file and i don't know how (without 'system'-instruction because it's a minimized dos version without these instructions).
can someone give a hint...

thanks

Hi,
try to use CStdioFile. like the following:

filepath = "C:\\test.ini"
CStdioFile delFile;
delFile.Remove(filepath);

i hope that it's solve your problem.

thanks

but this is not the solution.
i need it for 16bit under dos. there aren't such things like cstdfile or cfile.

sorry but thanks

again Hi,
i think you can use remove function :

#include <stdio.h>

int main( void )
{
   if( remove( &quot;crt_remove.txt&quot; ) == -1 )
      perror( &quot;Could not delete 'CRT_REMOVE.TXT'&quot; );
   else
      printf( &quot;Deleted 'CRT_REMOVE.TXT'\n&quot; );
}

yes i mean this.

but my biggest problem is to remove all files.
because i handle over the path (eg 'f:\progs\test') and then i want delete every file in the path (recursive).

void DelDir(char *argv1, char *argv2)
{
//argv1 is drive (eg 'f')
//argv2 is path (eg 'progs\test')

struct _find_t sfile;
int result;
char buffer[256], buffer2[256];

strcpy(buffer,argv1);
strcat(buffer,":\\"
strcat(buffer,argv2);

result = _dos_findfirst(buffer, _A_SUBDIR, &sfile );

while( result == 0 )
{
if(sfile.attrib & _A_NORMAL)
{
strcpy(buffer2,argv2);
strcat(buffer2,"\\"
strcat(buffer2, sfile.name);

printf("%s\n", &buffer2);

_chmod(sfile.name, _S_IWRITE);

strcat(buffer,"\\"
strcat(buffer,sfile.name);

printf("%s\n", &buffer);

remove(buffer2);

DelDir(argv1,buffer);
}

result = _dos_findnext(&sfile);
}
}

what is wrong. it don't delete all files from subdirectory how it should...

void DelDir(char *argv1, char *argv2)
{
struct _find_t sfile;
int result;
char buffer[256];

strcpy(buffer,argv1);
strcat(buffer,":\\"
strcat(buffer,argv2);

strcat(buffer,"\\*.*"

result = _dos_findfirst(buffer, _A_NORMAL, &sfile );

while( result == 0 )
{
printf("%s\n", &buffer);

_chmod(sfile.name, _S_IWRITE);

if(remove(sfile.name) != -1)
{
printf("%s delete successful\n", &sfile.name);
}
else
{
printf("%s not deleted\n", &sfile.name);
}

result = _dos_findnext(&sfile);
}
}

Hi,
the following program run OK on my pc.
probebly you must go to specific directory(_chdir)
and then delete files.

#include "stdafx.h"
#include <afx.h>
#include &quot;sys\stat.h&quot;
#include &quot;direct.h&quot;
#include &quot;io.h&quot;
#include &quot;iostream.h&quot;
#include &quot;string.h&quot;

void DelDir(char *, char *);

int main(int argc, char* argv[])
{
  DelDir(&quot;D&quot;,&quot;test&quot;);

  return 0;

}

void DelDir(char *argv1, char *argv2)
{
    struct _finddata_t  sfile;
    int result;
	long hFile;
    char buffer[256];              
    
    strcpy(buffer,argv1);       
    strcat(buffer,&quot;:\\&quot;);       
    strcat(buffer,argv2);

    _chdir(buffer);    
    strcat(buffer,&quot;\\*.*&quot;);

	hFile = _findfirst(buffer, &sfile );
    if(hFile != -1)
    {
      result = 0;
      while( result == 0 )
	  { 
        printf(&quot;%s\n&quot;, &buffer);
        printf(&quot;%s\n&quot;, &sfile.name);
            
        if(_chmod(sfile.name, _S_IWRITE) != -1)
		{
          if(remove(sfile.name) != -1)
            printf(&quot;%s delete successful\n&quot;, &sfile.name);
          else
            printf(&quot;%s not deleted\n&quot;, &sfile.name);
		}
        result = _findnext(hFile,&sfile);            
	  }
      _findclose( hFile );
    }
	else
      printf(&quot;no file founded\n&quot;);

	
}

thanks

i have also any other question.
if i have a long path name with a lot of files then i get a stack overflow.
what can i do i your mind?

 

[BEHZADTALA]

give me an example. how many files and how is
your path?

 

[willi808]

path:
f:\eb\ebooks\hacking\anleit~1\sortie~1\alles_~1\anti_t~1\htmlfiles before = 1851
files after = 1076

 

[BEHZADTALA]

i take the path
test\\f\\eb\\ebooks\\hacking\\anleit~1\\sortie~1\\alles_~1\\anti_t~1\\html
and 2575 files in html.
my program runs succesfull and deletes all files without
Errors.
Maybe you have problem with your Environment Setting.

 

[willi808]

can it caused by array's with the size of 256?

 

[BEHZADTALA]

No, idon't think. i suggest you go to

http://msdn.microsoft.com/library/

site and
search "stack overflow".
i am sure you find your answer.

[willi808]

thanks,
the size of my stack wasn't enough...
but when i reach the deepest path it stops deleting!?
