Jak dostat info. z index.dat? – C / C++ – Fórum – Programujte.com

Mohl by mi nekdo prosim poradit jak mam nacist ze souboru index.dat adresy navstivenych stranek a cas navstiveni?
Zkousel jsem to tak ze jsem nasel string URL a pak jsem poskocil o 104 bytu a nechal jsem vypsat adresu viz. zdrojak nize.
Ale stim casem si nevim nejak rady, zkousel jsem to pomoci programu PASCO, ale nejak jsem nepochopil jak tam nacitaji ten soubor.

link na PASCO: http://odessa.cvs.sourceforge.net/odessa/pasco/src/pasco.c?view=markup
jinak tady je link na pdf, ktere popisuje strukturu index.dat: http://www.foundstone.com/pdf/wp_index_dat.pdf

Prosim poradte jak to mam udelat.

#include <tchar.h>
#include <stdio.h>
#include <stdlib.h>

#define BUFSIZE 32

int main()
{

FILE *f;
int c,zacatek;
char szIndexPath[BUFSIZE];

f = fopen("C:\\Documents and Settings\\xxx\\Cookies\\index.dat","rb");

//
/* Soubor je oteveren */
//
if ( f <= 0 )
{
printf("ERROR - Soubor index.dat nejde otevrit!\n\n");
}
else;
printf("OK\n\n");

while((c = fgetc(f))!=EOF) {
if( c !='U' ) continue;
if( fgetc(f) != 'R' ) continue;
if( fgetc(f) != 'L' ) continue;

zacatek=SEEK_CUR ;
printf("%d\n", zacatek);

//URL
fseek(f, 0x68-0x3, zacatek);
fgets(szIndexPath, BUFSIZE, f);
printf("%s\n", szIndexPath);

}
return 0;
}

PLSSSSSSSSSS poradte jak to mam udelat s tim casem

No ked najdes URL, posunies sa o 8 bajtov(za tvojim CASEom je to uz len 5 bajtov) dalej a nacitas dalsich 8 bajtov (cas).Potom uz len pouzijes na to tuto funkciu time_t win_time_to_unix ktorej das ako argument pole tvojich nacitanych 8mich bajtov.To je last Modified TimeStamp.Ak nacitas dalsich 8 bajtov tak to je Last Accessed TimeStamp.

//fcia ktora prevracia poradie bajtov

unsigned int bah_to_i( char *val, int size ) {

  int total;

  int i;



  total = 0;

  for ( i=0; i < size; i++ ) {

     total += ((unsigned char)val[i] << 8*i);

  }



  return total;

}



//funkcia ktora ti skovertuje tych 8 bajtov na cas

time_t win_time_to_unix( char *val ) {

   unsigned long low, high;

   double dbl;

   time_t total;

  

   char fourbytes[4];

  

   fourbytes[0] = val[0];

   fourbytes[1] = val[1];

   fourbytes[2] = val[2];

   fourbytes[3] = val[3];

 

   low = bah_to_i( fourbytes, 4 );

 

   fourbytes[0] = val[4];

   fourbytes[1] = val[5];

   fourbytes[2] = val[6];

   fourbytes[3] = val[7];

 

   high = bah_to_i( fourbytes, 4 );

 

   dbl = ((double)high)*(pow(2,32));

   dbl += (double)(low);

 

   if ( dbl==0 ) {

     return 0;

   }

 

   dbl *= 1.0e-7;

   dbl -= 11644473600;

   total = (double)dbl; 

   return total;

}

time_t UnixTime = 10(na-7) * nacitana_hodnota + 11644473600

To sn3d: Mohl by jsi mi jeste prosim poradit u funkce: ctime_r(); mi to pise ze neni deklarovany identifikator.
Jinak ten druhy zpusob by jsem rad vyzkousel, ale je problem v tom ze v programovani nejse moc zbehly (jak jsi urcite poznal :-) ), tak chci nejprve zprovoznit ten lehci zpusob a pak se zkusim vrhnoput na ten slozitejsi.

Niesom si isty ale myslim ze M$ nepozna fciu ctime_r.V M$ sa time_t musi skonvertovat na tm strukturu pomocou fcie localtime a potom mozes z nej ziskat text pomocou fcie asctime.

  tm* temp;

  temp = localtime(&accesstime);

  printf( "Time is: %s", asctime(temp) );

To sn3d:

Tak tu chybovou hlasku mi to uz nepise, ale spadne to u printf( "Time is: %s", asctime(temp) );, vypada to ze v accesstime je neco co tam nema byt,
asi spatne volam fci bah_to_i(), nebo win_time_to_unix() mohl by jsi prosimte poradit co delam zpatne.



int main()
{

FILE *f;
int c,zacatek,x;
char szIndexPath[BUFSIZE], cs[8];
time_t accesstime;
struct tm *temp;

f = fopen("C:\\Documents and Settings\\xxx\\Cookies\\index.dat","rb");



// Soubor je oteveren
if ( f <= 0 )
{
printf("ERROR - Soubor index.dat nejde otevrit!\n\n");
}
else;
printf("OK\n\n");

while((c = fgetc(f))!=EOF) {
if( c !='U' ) continue;
if( fgetc(f) != 'R' ) continue;
if( fgetc(f) != 'L' ) continue;

zacatek=SEEK_CUR ;
printf("%d\n", zacatek);

//CAS
fseek(f, 13, zacatek);

x=bah_to_i( cs, 8 );
accesstime=win_time_to_unix(cs);

temp = localtime(&accesstime);
printf( "Time is: %s", asctime(temp) );


//URL
fseek(f,88, zacatek);
fgets(szIndexPath, BUFSIZE, f);
printf("%s\n", szIndexPath);


}
return 0;




}

No na prvy pohlad:

       ...

       x=bah_to_i( cs, 8 ); //toto ej tu na co?Zbytocne, vyhodit

       accesstime=win_time_to_unix(cs); //kde nacitavas data do premennej cs??

       ...
