频繁使用 Process32First 失败解决方法

频繁使用 Process32First 失败
实时刷新 进程列表。刷新个十几次后，Process32First返回失败

不知道是什么原因。

C/C++ code

fGetProcessList(){        m_list.ResetContent();    HANDLE hSnap;    CString strPath;    LPTSTR path = new TCHAR[MAX_PATH];    hSnap = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0);    PROCESSENTRY32 process;    process.dwSize=sizeof(PROCESSENTRY32);    BOOL bResult = Process32First(hSnap,&process);    while (bResult)    {        ZeroMemory(path,MAX_PATH);        for (int i=0;i<MAX_PATH;i++)            path[i] = process.szExeFile[i];        strPath = path;                m_listLog.InsertString(0,strPath );        bResult = Process32Next(hSnap,&process);    }    delete path;    path = NULL;    CloseHandle(hSnap);}
