#include "stdafx.h"
#include <iostream>
using namespace std;
#include <comdef.h>
#include <Wbemidl.h>

# pragma comment(lib, "wbemuuid.lib")

            << "Error code = 0x" 
            << hex << hres << endl;
        return 1;              // Program has failed.
    }

    hres =  CoInitializeSecurity(
        NULL,

        CoUninitialize();

    }

    // Obtain the initial locator to Windows Management
    // on a particular host computer.
    IWbemLocator *pLoc = 0;

    hres = CoCreateInstance(

    if (FAILED(hres))
    {
        cout << "Could not connect. Error code = 0x"

    );

    if (FAILED(hres))

        cout << "Could not set proxy blanket. Error code = 0x" 
             << hex << hres << endl;
        pSvc->Release();
        pLoc->Release();     
        CoUninitialize();
        return 1;               // Program has failed.
    }


    // Use the IWbemServices pointer to make requests of WMI.

            if(0 == uReturn)
            {
                break;
            }

            VARIANT vtProp;

            // Get the value of the Name property
            hres = pclsObj->Get(L"Name", 0, &vtProp, 0, 0);
            wcout << "Process Name : " << vtProp.bstrVal << endl;
            VariantClear(&vtProp);
        }
         
    }
 
    // Cleanup
    // ========

    pSvc->Release();
    pLoc->Release();     
    CoUninitialize();

    return 0;   // Program successfully completed.
}

整理之后：

WMIQuery test0;

test0.Initial();
if(!test0.WQLquery(0,0,teststr))teststr="查询失败";
else cout<<"teststr";

这句得到的是CPU名字根据上表查询。
