主流程中加特殊逻辑可以用类封装

 // 把WMI的初始化提前，防止被GetHardwareInfo.dll，导致初始化失败
 CWmiInfo::GetInstance()->Init();

void CWmiInfo::Init() {  HRESULT hRes = CoInitializeSecurity(NULL, -1, NULL, NULL, RPC_C_AUTHN_LEVEL_PKT, RPC_C_IMP_LEVEL_IMPERSONATE, NULL, EOAC_NONE, NULL);  if (!(SUCCEEDED(hRes) || RPC_E_TOO_LATE == hRes))   return;

 hRes = CoCreateInstance(CLSID_WbemLocator, 0,CLSCTX_INPROC_SERVER, IID_IWbemLocator, (LPVOID*)&m_pWbemLoc);   ATLVERIFY(SUCCEEDED(hRes));

 InitNetDetector(); }
