Obtain the cpu id and the serial number of the hard disk.

1. Obtain the CPU ID

DWORD cdlgregister: getcpuid () <br/>{< br/> DWORD dwid1, dwid2, dwid3, dwid4; <br/> char szcompany [13]; <br/> pchar pcompany = szcompany; </P> <p> // DWORD dwcpu; </P> <p> szcompany [12] = 0; <br/> _ ASM <br/> {<br/> pushfd <br/> pushad <br/> // obtain the ID of the CPU <br/> mov eax, 1 // function no. <br/> _ emit 0x0f <br/> _ emit 0xa2 <br/> mov dwid1, eax <br/> mov dwid2, EBX <br/> mov dwid3, ECx <br/> mov dwid4, EDX </P> <p> // obtain the name of the CPU manufacturer <br/> mov EDI, pcompany // function no. <br/> mov eax, 0 <br/> _ emit 0x0f <br/> _ emit 0xa2 <br/> mov eax, EBX <br/> stosd <br/> mov eax, EDX <br/> stosd <br/> mov eax, ECX <br/> stosd <br/> popad <br/> popfd <br/>}</P> <p> DWORD dwresult = 0; <br/> DWORD dwtemp1 = dwid1 <12; <br/> DWORD dwtemp2 = dwid2 <8; <br/> DWORD dwtemp3 = dwid3 <4; </P> <p> dwresult = dwtemp1 + dwtemp2 + dwtemp3 + dwid4; </P> <p> return dwresult; <br/>}

2. Obtain the serial number of the hard drive C.

DWORD cdlgregister: getharddisknum () <br/>{< br/> char cvolume [256]; // <br/> char cfilesysname [256]; <br/> DWORD dwserialnum; // hard disk serial number <br/> DWORD dwfilenamelength; <br/> DWORD dwfilesysflag; </P> <p >:: getvolumeinformation ("C: // ", cvolume, 256, & dwserialnum, & dwfilenamelength, <br/> & dwfilesysflag, cfilesysname, 256); </P> <p> return dwserialnum; <br/>}
