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

The simplest language to call COM components is, of course, C + +, but in some cases it has to be in C language. This article describes the methods for calling COM components in C language.To better understand C's approach, let's take a look at how C + + calls COM components.First, C + + modeStarting with Windows 7, the taskbar can display a progress bar, which is an example of this interface.ITaskbarList4 *ptaskbar = nullptr; HRESULT

Grid 2 ID3DXBuffer The ID3DXBuffer interface is a generic data structure. This interface has two methods. · LPVOID GetBufferPointer (); returns the pointer pointing to the starting position of data in the cache. · DWORD GetBufferSize (); return the cache size, in bytes. To ensure the versatility of this interface, this interface uses the void type pointer, which means that we must implement the data type to be stored. For example, the D3DXLoadMeshFromX function returns the adjacent information
