仅在《主机性能监控之wmi 获取系统信息及内存性能信息》代码中添加一个函数

使用的结构体位为Win32_Process

class Win32_Process : CIM_Process
{
  string Caption;
  string CommandLine;
  string CreationClassName;
  datetime CreationDate;
  string CSCreationClassName;
  string CSName;
  string Description;
  string ExecutablePath;
  uint16 ExecutionState;
  string Handle;
  uint32 HandleCount;
  datetime InstallDate;
  uint64 KernelModeTime;
  uint32 MaximumWorkingSetSize;
  uint32 MinimumWorkingSetSize;
  string Name;
  string OSCreationClassName;
  string OSName;
  uint64 OtherOperationCount;
  uint64 OtherTransferCount;
  uint32 PageFaults;
  uint32 PageFileUsage;
  uint32 ParentProcessId;
  uint32 PeakPageFileUsage;
  uint64 PeakVirtualSize;
  uint32 PeakWorkingSetSize;
  uint32 Priority;
  uint64 PrivatePageCount;
  uint32 ProcessId;
  uint32 QuotaNonPagedPoolUsage;
  uint32 QuotaPagedPoolUsage;
  uint32 QuotaPeakNonPagedPoolUsage;
  uint32 QuotaPeakPagedPoolUsage;
  uint64 ReadOperationCount;
  uint64 ReadTransferCount;
  uint32 SessionId;
  string Status;
  datetime TerminationDate;
  uint32 ThreadCount;
  uint64 UserModeTime;
  uint64 VirtualSize;
  string WindowsVersion;
  uint64 WorkingSetSize;
  uint64 WriteOperationCount;
  uint64 WriteTransferCount;
};

添加函数为

 1 bool CMyWMI::QueryProcessInfo()
 2 {
 3     HRESULT hres; //定义COM调用的返回  
 4     IEnumWbemClassObject* pEnumerator = NULL;  
 5     bool bRet = false;
 6 
 7     try{
 8         hres = pSvc_->ExecQuery(  
 9             bstr_t("WQL"),     
10             bstr_t("SELECT * FROM Win32_Process"),  
11             WBEM_FLAG_FORWARD_ONLY | WBEM_FLAG_RETURN_IMMEDIATELY,   
12             NULL,  
13             &pEnumerator);  
14 
15         if (FAILED(hres))  
16         {  
17             throw exception("ExecQuery() error.");
18         }  
19 
20         while (pEnumerator)  
21         {
22             IWbemClassObject *pclsObj;  
23             ULONG uReturn = 0;  
24 
25             HRESULT hr = pEnumerator->Next(WBEM_INFINITE, 1,   
26                 &pclsObj, &uReturn);  
27             if(0 == uReturn)  
28             {  
29                 break;  
30             }  
31 
32             GetInfo(L"Caption",pclsObj);
33             GetInfo(L"Handle",pclsObj);
34             GetInfo(L"ExecutablePath",pclsObj);
35             cout << endl;
36 
37             pclsObj->Release(); 
38         }
39 
40 
41     }catch(exception& e)
42     {
43         cout << e.what() << endl;
44         if(pEnumerator != NULL)
45         {
46             pEnumerator->Release(); 
47             pEnumerator = NULL;
48         }
49         return bRet;
50     }
51 
52 
53     if(pEnumerator != NULL)
54     {
55         pEnumerator->Release(); 
56         pEnumerator = NULL;
57     }
58 
59     bRet = true;
60     return bRet;
