Hello,
I´m sorry to bother, but i really need some help here.
I have this C code that when compiled into a libray for
the oldtimer Clipper, will give me the HD Serial Number
From Factory!, not the serial number tha is stamped
when you format the HD.
If anyone could translate this code to VB i´ll appreciated,
but if it´s not possible, then could be possible that you
can convert it to a .dll to have it working in VB?
Well hope this is possible...;))
Code:
CLIPPER USAGE:
Passed numeric int, 0 or 1 i.e. IDEHDSNUM( 0 ) or IDEHDSNUM( 1 )
Where 0 = First Hard Drive
Where 1 = Second Hard Drive
Will return a "0" string if nothing is passed or int is greater that 1
Clipper source example:
? IDEHDSNUM(0) // Display serial number of first IDE Hard Drive
? IDEHDSNUM(1) // Display serial number of second IDE Hard Drive
? IDEHDSNUM(3) // Returns "0" Character
*/
#include "extend.h"
char *getascii (unsigned int in_data [], int off_start, int off_end);
CLIPPER idehdsnum()
{
unsigned int dd [256]; /* Disk Data */
unsigned int dd_off; /* Disk Data offset */
int hd; /* Hard Drive number parameter (0 or 1) */
if ( (PCOUNT == 1) && (ISNUM(1)) )
{
hd = _parni(1); /* Assign interger parameter from Clipper for
the Hard Drive to be checked */
if( hd > 1 )
{
_retclen( "0", 1 ); /* Nothing greater that 1 allowed */
return;
}
while (inp (0x1F7) != 0x50); /* Wait for controller not busy */
outp (0x1F6, ( hd == 0 ? 0xA0 : 0xB0)); /* Get first/second drive */
outp (0x1F7, 0xEC); /* Get drive info data */
while (inp (0x1F7) != 0x58); /* Wait for data ready */
for (dd_off = 0; dd_off != 256; dd_off++) /* Read "sector" */
dd [dd_off] = inpw (0x1F0);
/* Return Hard Drive serial number as a string back to Clipper */
_retclen( getascii (dd, 10, 19), strlen(getascii (dd, 10, 19)));
}
else
_retclen( "0", 1 ); /* Send string of "0" back to indicate and error */
return;
}
char *getascii( unsigned int in_data [], int off_start, int off_end )
{
static char ret_val [255];
int loop, loop1;
for (loop = off_start, loop1 = 0; loop <= off_end; loop++)
{
ret_val [loop1++] = (char) (in_data [loop] / 256); /* Get High byte */
ret_val [loop1++] = (char) (in_data [loop] % 256); /* Get Low byte */
}
ret_val [loop1] = '\0'; /* Make sure it ends in a NULL character */
return(ret_val);
}

Saludos...;)

I don't think this can be done in VB. You will have to make a dll. good luck
