Body
I created a ATL windows less control and the class definition is like this: <pre><code> class ATL_NO_VTABLE CRSPClient : public IObjectSafetyImpl<CRSPClient, INTERFACESAFE_FOR_UNTRUSTED_CALLER|INTERFACESAFE_FOR_UNTRUSTED_DATA>, public CComObjectRootEx<CComSingleThreadModel>, public IDispatchImpl<IRSPClient, &IID_IRSPClient, &LIBID_axBanckleRSPClientLib, /*wMajor =*/ 1, /*wMinor =*/ 0>, public IPersistStreamInitImpl<CRSPClient>, public IOleControlImpl<CRSPClient>, public IOleObjectImpl<CRSPClient>, public IOleInPlaceActiveObjectImpl<CRSPClient>, public IQuickActivateImpl<CRSPClient>, public IViewObjectExImpl<CRSPClient>, public IOleInPlaceObjectWindowlessImpl<CRSPClient>, #ifdef _WIN32_WCE // IObjectSafety is required on Windows CE for the control to be loaded correctly public IObjectSafetyImpl<CRSPClient, INTERFACESAFE_FOR_UNTRUSTED_CALLER>, #endif public CComCoClass<CRSPClient, &CLSID_RSPClient>, public CComControl<CRSPClient> </code></pre> Then for some purpose I need to post message to the window. I tried to get the handle of the window in quite many ways and ALL of them failed: <pre><code> HWND CRSPClient::GetHwnd() { HWND hwndRet = NULL; // hwndRet = m_hWnd; //IOleInPlaceActiveObjectImpl<CRSPClient>::GetWindow(&hwndRet); //IOleWindow<CRSPClient>::GetWindow(&hwndRet); //this->m_spInPlaceSite->GetWindow(&hwndRet); //CComQIPtr<IOleInPlaceSite> spSite = this->m_spClientSite; //spSite->GetWindow(&hwndRet); //hwndRet = ::WindowFromDC(GetDC()); return hwndRet; } </code></pre> Anybody know be there any way to get the HWND? OMG I'm totally frustrated by microsoft's great ATL framework!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
