如何用PB得到CPU或硬盘的号

如何用PB得到CPU或硬盘的号

在多cpu、多核中，会随机的获得不同的序列号。
这就为根据cpu序列号来制作注册机带来了很大的麻烦。
Windows2000/xp允许设置进程和线程的亲缘性。
换句话说，可以控制哪个CPU能够运行某些线程。
这称为硬亲缘性。
Windows提供了设置亲缘性的函数SetProcessAffinityMask。
使用它可控制获取指定cpu的序列号

#include "StdAfx.h" #include ".\puiddisk.h" #define _WIN32_DCOM #include <iostream> using namespace std; #include <comdef.h> #include <Wbemidl.h># pragma comment(lib, "wbemuuid.lib") CpuIDDisk::CpuIDDisk(void) { GetInfomation(); }CpuIDDisk::~CpuIDDisk(void) { } int CpuIDDisk::GetInfomation(void) { HRESULT hres; //步骤1：不是必须的，COM只须也只能初始化一次 hres = CoInitializeEx(0, COINIT_MULTITHREADED ); if (FAILED(hres)) { return 1; //初始化COM异常：注意，COM只须也只能初始化一次 } //步骤2：不是必须的，COM只须也只能设置一次 //Set general COM security levels hres = CoInitializeSecurity( NULL, -1, // COM authentication NULL, // Authentication services NULL, // Reserved RPC_C_AUTHN_LEVEL_DEFAULT, // Default authentication RPC_C_IMP_LEVEL_IMPERSONATE, // Default Impersonation NULL, // Authentication info EOAC_NONE, // Additional capabilities NULL // Reserved ); if (FAILED(hres)) { CoUninitialize(); return 1; // Program has failed. } //以上不是必须的，若已有“::COMInit();”，则要跳过 //步骤3： Obtain the initial locator to WMI IWbemLocator *pLoc = NULL; hres = CoCreateInstance( CLSID_WbemLocator, 0, CLSCTX_INPROC_SERVER, IID_IWbemLocator, (LPVOID *) &pLoc); if (FAILED(hres)) { CoUninitialize(); return 1;//Failed to create IWbemLocator object } //步骤4：Connect to WMI through the IWbemLocator::ConnectServer method IWbemServices *pSvc = NULL; hres = pLoc->ConnectServer( _bstr_t(L"ROOT\\CIMV2"), // Object path of WMI namespace NULL, // User name.

用外部函数获取比较方便。 比如：getcpuid.dll //函数声明 function long getcpuid() library "getcpuid.dll"  //范例： string cpuid cpuid=string(getcpuid())
