guidgen.exe tool. 2. Macro declare_interface _ declares the interface. The first parameter of the macro is the interface name, and the second parameter is the base class of the interface. The declare_interface macro is used to declare interfaces without the base class. 3. the macro stdmethod declares the methods in the interface. the return value of this method is hresult. pure is interpreted as "; = 0";, that is, this method is a pure virtual functi

DirectShow is a set of interfaces defined by Microsoft. It consists of different interfaces, such as ibasefilter and ipin. The relationship between these interfaces forms the DirectShow architecture. The DirectX SDK provides a C ++ baseclasses interface. These implementations are mature and complete, so we don't need to re-develop a class library to implement the dirctshow interface, just use it directly. DirectShow programming is filter programming. Different filters are implemented based on fu

levels of vibration function, and the larger the number, the stronger the adjustment capability. When the device has different levels of vibration capabilities, I can use the vibratenote structure for detailed settings. How can we start using the vibration function? The mobile phone SDK provides the vibrate function: Hresult vibrate (Dword cvn,Const vibratenote * rgvn,Bool frepeat,DWORD dwtimeout); It provides different amplitude, different frequency

3. For com_interface_entry_tear_off (IID, x), refer to the ATL routines beeper and commap. The purpose of using this macro is to put some rarely used interfaces in a single component for implementation.This component is created only when this interface is found, and is released when its reference count is reduced to 0. MeWe know that components in ATL are implemented through multi-inheritance. Every time an interface is inherited, the system willOne more virtual function table pointer. With thi

, it searches for this array to see if there is a factory class object that matches clsid. When it finds a matched CLSID, it creates a class factory object and returns the class factory pointer to cogetclassobject. Then the client can call iclassfactory based on the class factory pointer returned :: the createinstance method creates a component, and the class factory creates a COM component based on the methods defined in the array.The factory template contains the following variables:const WCHA
