为了维护我们软件的人员的权益,目前,我们软件人员在保护小软件用的最多的办法是机器码,由CPU、硬盘、BIOS等序列号组成,网上发布很多类似的源码,但是,经我一段时间测试,有以下问题:
1、硬盘序列号在98下不稳定,序列号会变,比如网上出现频率较高,由于字数有限,我不全贴了:
......
begin
Result := ''; // 如果出错则返回空串
if SysUtils.Win32Platform=VER_PLATFORM_WIN32_NT then begin// Windows NT, Windows 2000
// 提示! 改变名称可适用于其它驱动器,如第二个驱动器: '\\.\PhysicalDrive1\'
hDevice := CreateFile( '\\.\PhysicalDrive0', GENERIC_READ or GENERIC_WRITE,
FILE_SHARE_READ or FILE_SHARE_WRITE, nil, OPEN_EXISTING, 0, 0 );
end else // Version Windows 95 OSR2, Windows 98
hDevice := CreateFile( '\\.\SMARTVSD', 0, 0, nil, CREATE_NEW, 0, 0 );
if hDevice=INVALID_HANDLE_VALUE then Exit;
try
FillChar(SCIP,SizeOf(TSendCmdInParams)-1,#0);
FillChar(aIdOutCmd,SizeOf(aIdOutCmd),#0);
cbBytesReturned := 0;
// Set up data structures for IDENTIFY command.
with SCIP do begin
cBufferSize := IDENTIFY_BUFFER_SIZE;
// bDriveNumber := 0;
with irDriveRegs do begin
bSectorCountReg := 1;
bSectorNumberReg := 1;
// if Win32Platform=VER_PLATFORM_WIN32_NT then bDriveHeadReg := $A0
// else bDriveHeadReg := $A0 or ((bDriveNum and 1) shl 4);
bDriveHeadReg := $A0;
bCommandReg := $EC;
end;
end;
if not DeviceIoControl( hDevice, $0007c088, @SCIP, SizeOf(TSendCmdInParams)-1,
@aIdOutCmd, SizeOf(aIdOutCmd), cbBytesReturned, nil ) then Exit;
finally
CloseHandle(hDevice);
end;
with PIdSector(@IdOutCmd.bBuffer)^ do begin
ChangeByteOrder( sSerialNumber, SizeOf(sSerialNumber) );
(PChar(@sSerialNumber)+SizeOf(sSerialNumber))^ := #0;
Result := PChar(@sSerialNumber);
end;2、同一机子98下与2000下硬盘或CPU序列号不同,有没有办法统一?谢谢各位提供帮助!

谢谢您的回答,光是CPU序列号,重复比例很高,我们一般再并上硬盘序列号,但是硬盘序列号一、在98下不稳定,会变;二、同一机子,98或2000下不同。请继续指教,谢谢!
你测试下看他们的在98下能否正确取出来。
to xixuemao():的确方法很多,但是类似很多,大多我测试过,98下不稳定。
