  • COM Tip(1)

    一.AtlAdvise

    Creates a connection between an object's connection point and a client's sink.

    HRESULT AtlAdvise(
       IUnknown* pUnkCP,
       IUnknown* pUnk,
       const IID& iid,
       LPDWORD pdw 
    );
    pUnkCP

    [in] A pointer to the IUnknownof the object the client wants to connect with.

    pUnk

    [in] A pointer to the client's IUnknown.

    iid

    [in] The GUID of the connection point. Typically, this is the same as the outgoing interface managed by the connection point.

    pdw

    [out] A pointer to the cookie that uniquely identifies the connection.

    二.AtlUnadvise

    Terminates the connection established through AtlAdvise. 
    HRESULT AtlUnadvise(
       IUnknown* pUnkCP,
       const IID& iid,
       DWORD dw 
    );
    pUnkCP

    [in] A pointer to the IUnknownof the object that the client is connected with.

    iid

    [in] The GUID of the connection point. Typically, this is the same as the outgoing interface managed by the connection point.

    dw

    [in] The cookie that uniquely identifies the connection.

    三.COM_INTERFACE_ENTRY2

     
    Use this macro to disambiguate two branches of inheritance. 
    For example, if you derive your class object from two dual interfaces, 
    you expose IDispatch using COM_INTERFACE_ENTRY2 since IDispatch can be obtained from either one of the interfaces.
     

    四.CWinApp::RunEmbedded

    Call this function to determine whether the "/Embedding" or "-Embedding" option is present, 
    which indicates whether the server application was launched by a client application.

    五.CWinApp::RunAutomated

    Call this function to determine whether the "/Automation" or "-Automation" option is present, which indicates whether the server application was launched by a client application.
