主要是使用KernelIOControl这个函数
CString GetSerialNumberFromKernelIoControl()
{
DWORD dwOutBytes;
const int nBuffSize = 4096;
byte arrOutBuff[nBuffSize];
BOOL bRes = ::KernelIoControl(IOCTL_HAL_GET_DEVICEID,
0, 0, arrOutBuff, nBuffSize, &dwOutBytes);
if (bRes)
{
CString strDeviceInfo;
for (unsigned int i = 0; i<dwOutBytes; i++)
{
CString strNextChar;
strNextChar.Format(TEXT("%02X"), arrOutBuff);
strDeviceInfo += strNextChar;
}
CString strDeviceId =
strDeviceInfo.Mid(40,2) +
strDeviceInfo.Mid(45,9) +
strDeviceInfo.Mid(70,6);
return strDeviceId;
}
else
{
return _T("");
}
}
